Upgrade iPhone Speed | Hardware speed up iPhone

Upgrade your iPhone speed | Speed up you iPhone by hardware modification


I'm sure from what you know or someone told you that the iPhone speed is can't be upgraded. But I'm saying the otherwise.
I'm NOT talking about software tune-up shit. I'm talking about the hardware upgrade just like a computer by adding more RAM, change CPU or SSD.


Today I would like to share how the speed upgrade is possible. But the works can be only carried by an expert like me.

Because I get the non-stop people asking me this kind of question -
"is it the bigger storage of the iPhone and lagger (slow) it will be?"
The answer is NO.
Because the speed of it is entirely up to the memory chip.
Exactly like you buying an SD card which has their own performance is stated.



And the memory chip of iPhones are using is called NAND flash. Sandisk, Toshiba, Hynix, and Samsung are the NAND supplier to Apple.

A lot of people expect all iPhone hardware is the totally same performance compare to the same model, but now I tell you it is NOT. That's why sometimes your friend iPhone run better than yours. Not only in term of speed. The cellular or network performance is also different. You never know what you buy. Different batch and location can have differences.   


So back into topic.
Apple is smart. Or I can say the supplier of NAND too. They use a lower grade of NAND which is slower.

Lower Tech = Cheaper Cost.

Below is the comparison of 32GB and 256GB NAND speed of iPhone 6S that is running PCIe


32GB NAND PCIe speed
32GB speed test



256GB NAND PCIe speed
256GB speed test

As you can see from above.
32 GB is running an average speed of 48 MB/s (384Mbps)
256 GB is running an average speed of 67 MB/s (536Mbps)

It's about 40% faster.

The photo I show is only the writing speed. The reading speed is much more but I want to keep the article short.

I'm not bothering to explain TLC and MLC different. Because what I'm doing today is to tell you that by changing the storage of the iPhone or iPad, the speed can be upgraded as well.

But please don't think the Toshiba is slower. Other brands are also slow if they are low capacity storage for iPhone and iPad. (16GB or 32GB)


AND
don't expect it's a very noticeable speedup. Because a lot of works are still depending on the CPU and the RAM especially when it comes to multitasking.

BUT
It's noticeable for video editing, loading a bunch of photos, compressing a file and sending, loading game time, backup and more...

Below photos are our daily job.

Have you seen 512 GB iPhone 6S selling in Apple?

Unlock iPad Apple ID Guide - iPad Pro 12.9


First of all, if you found any lost device, please return to owner.

If for some reason, you need help, but Apple doesn't help you.
Then you can find a PRO to do this. 



iPad Pro 12.9 4G
Tips: Cellular version of iPad and WiFi Version iPad does not unlock the same way.

and today my topic is "How to unlock an iPad Pro 12.9 Cellular version".

First, I let you know how Apple ID lock works, or I should say how activation server works.

The device locked status is not based on memory inside or the hardware. Means no matter how you reformat or reset the software, it's still unable to activate.
Because to activate, the server will check your device's IMEI, Serial Number and more. So it's their server that preventing you from unlocking it.

Method 1 - If you are a pro hacker, then hack their server, but I think the FBI will arrive at your doorstep. By the way, a few years ago they fired many Apple insiders that offer unlock under the table.

Method 2 - Why not we reprogram the IMEI and serial number to fool the server?
Yes. But as I said before, the server will check the information of the device, if it's not in their list, then it can't be activated. No random typing allow.  

But what if I have a legit IMEI and SN (Serial Number) which is from another device?
Yes, it will work if that SN is not in locked status, or we own that Apple ID.
But reprogram the IMEI is not possible. Because IMEI is stored in Baseband CPU which we don't have any tools to hack in. And it's purely hardware and unprogrammable.  
(Baseband CPU is a long story to explain, I might write another article for it)

But the SN is possible, as I said before in other topics, Apple doesn't own any factory to make Memory or Hard Disk - and the iPhone and iPad are using NAND flash memory.
This is why we can use NAND programming tools to re-write it. But only the SN can change.
If we just change SN, but the IMEI is still remaining same, the server will still be blocking you to activate.

It means only the device that has IMEI is iPads SIM card models 
(iPad cellular) or the iPhone.

So if we just reprogram the SN on iPads WiFi models, it can be unlocked. 

What about iPads Cellular version?
Easy, we just disable the Baseband (SIM card function) and then convert the iPad cellular to become a WiFi model. After that then change the SN, and it's done.

If so, then the iPhone can do?
No. Because if you disable it on the iPhone, then it's not a phone anymore. You lost the SIM function means you spoiled the phone. They won't let you activate a brick.


So back to the topic...
To unlock the Cellular version iPad Pro 12.9 4G

The first thing is we need to remove a resistor on the motherboard and that will change the iPad become a WiFi version.
How to convert iPad Pro 12.9 4G to WiFi

But don't restore it yet.


iPad Pro 12.9 4G logicboard
Take the whole board out of the housing.
Why? Because we need to remove the NAND to reprogram it.


iPad PRO NAND
Tips: Be careful removing the NAND IC, you sure don't want overheat affected RAM or CPU and end up unable to power on or 4014 error.  Only professional like me can re-ball the CPU and RAM.
So I advise you cut the shield that will absorb the heat away. Shield causing you to take longer time remove it.

After you removed the NAND, put into NAND programming tool to write a new SN, WiFi, and BT address. This 3 info will be verified by activation server. If one of it is incorrect or it doesn't come from the same device, then you will be still unable to activate. Remember, click unbind the WiFi too. 

Then solder the NAND back to the logic board. 

You think you're done?
No, not yet.
Because the Cellular model and WiFi model's WiFi chipset is not the same. 
The WiFi button will be grey out, WiFi cannot be turned on until we change a correct WiFi chipset for it. 



iPad Pro 12.9 WiFi IC code
So we need to buy the WiFi model's WiFI IC to replace it.
Tips: the chipset code end with 0045.

iPad PRO WIFI IC
Remove the WiFI IC is straightforward. You can heat this area very high temp.
Tips: But when you mount the new WiFi IC back, be sure use lower temp. Else the chipset itself will get shorted.
Finally, assemble the board and everything.
Connect into iTunes. Click Restore. It will download an iPad WIFI version firmware to restore.

Voila, it's done!
Tips: Always censored the SN. Because there might surprise people like my skill will use your SN. You'll be screw if you haven't log in Apple ID on it.


iPad remove iCloud
DONE !!
Click here for inquiry iPad unlock.

FAQs:
Q: Can I still update the iOS in the future?
A: Yes

Q: Can I use a new Apple ID after that?
A: Yes

Q: Will the "ex-owner" able to track it by GPS?
A: No. The whole device becomes a new device.

Q: Why they didn't block this kind of unlocking?
A: So far they won't. Because this method is very extreme and only the PRO with skill and tools can do it.

iPhone 7 Dead for no reason | iPhone Sudden Death Repair Article



How to repair sudden death iPhone motherboard


I still seeing countless of customers that iPhone been sabotaged by inexperience technician.
Many times they caused the customer more expensive to repair or either caused them to lost all the data memory.


I'm going to share a journey of how to repair a dead iPhone 7 that is fresh and nobody touch it yet.

This customer told us the phone suddenly off and unable to turn on anymore. Apple and other shop telling him is a motherboard problem.
Lucky he googled and decided to send it to much more experienced guy to do the works.  Thumb up!  :)

The well-prepared guy deserved good luck.


I love to repair this type of problem. Especially the phone becomes dead for no reason. Phone? Actually, I mean any model of smartphone.
But only meet condition below.
  • No hard fall
  • No liquid damaged
  • No third-party charger used
  • No modification of hardware
  • Just suddenly become dead for no reason.

I made a video on YouTube if you are lazy to read the article, you can watch the video instead.

Continue to scroll down for long article that with details, why and how.


The article has much more to say. If I make the video too long, no people have time to watch entire video.


                             


I love to repair this kind of case, ONLY when I'm the First-hand who fix it. 
Because - a lot of amateurs claim that they know how to repair the motherboard, but instead, they only know how to change the IC.
They don't know how to troubleshoot and would blindly change whatever IC that is related to power. Especially the "Power ic." 
Plus, some of them lousy soldering skill, they usually created a mess or more problem than it had. 


By the way... iPhone that suddenly becomes dead for no reason is usually because of a component failure. 


A component that is related to power.  
Might be an IC or small little thing like a capacitor. 
And most of the time, it is the capacitor.  


Because in term of lifespan:
 IC > capacitor





This is a capacitor that we see on a circuit board, inside TV or computer motherboard...
A capacitor has its own lifespan. It is just like a water tank, it will be broken if too old or overstress.

capacitor compare
Have you seen the bulging capacitors before? That's the problem. In the old days' people who repairing TV, they replaced a lot of these components that causing the TV malfunction.

Last time I fixed my Asus router by replacing faulty capacitors.
And my graphics card too.
You might wonder I can repair those too? Yes. for the sudden death issue, because most of the time I just need to fix the shorted components without a schematic.
But the iPhone uses a lot smaller size capacitor. As you can see, the red circle capacitors compare to my finger.
Some are tiny. Smaller than nose shit I can say.

So this kind of repair would be a simple job for me. But not for others...
In Malaysia, very few technicians are qualified to troubleshoot the iPhone motherboard problem.
Blindly changing parts or IC is those "fast repair shop" feature. Quick money.

Too bad that a lot of customers not knowing the difference between "fast repair shop" and "a specialist shop."

Louis Rossmann once said, "Mall shop" can't repair a thing. I bet the difference because I'm at the mall. LOL...   We should say never trust the "franchise repair shop," they just can't focus all the best technician in one place.
Best pros are always staying in one spot very long time.

Why not move into shop lot? I don't want the next morning open my shop and found out my roller shutter is half opened and inside is empty. You know what I mean in Malaysia.
The second benefit is the customers can wander around the mall while waiting. Easy parking and security...


Back to topic...

iPhone 7 motherboard shorted

 First step - Plug into Power Supply and read the responses.


When we haven't turn it on, it shouldn't be drawing any power.
And in this case, it's already drawing 0.8A when giving a good battery power which is 3.8v.
So this is the problem what we called "motherboard shorted"
For those who have some experience, they would think Oh yeah~ It's the VCC mainline shorted. Piece of cake.
But they found out the caps of vcc_main and batt_vcc have nothing short.
Example like this guy commented on my Youtube, screenshot below.



In my video, a pro can notice when the time I was giving the power slowly, the meter was showing the iPhone doesn't draw any power until reaching 1.8V. 

You can see the meter didn't rise until the 1.8V.

But once the power exceeds 2.0v above, the meter is showing immediately needle rising indicated something is drawing power.
To a much more experienced technician would already know something is tricky in this board.


That's why I said earlier, there are very few technicians that are qualified in the market.




Second Step - check for heated component 


If there is a water leak, the leaking spot will be cold.
But what if it's an electricity leak? Then the leaking spot will be hot.
Understand?

In the traditional way of repair, we will force it to continue to receive the voltage then use our fingers to touch the board every component one by one. To feel which one is hot and it's a problem.


But with a well-equipped guy like me, would immediately waste no time and to take out the thermal camera to scan it.
Screw the finger or rosin technique.

Found out one of the IC is very hot. 97℃ 

A normal guy would think: "Found the problem, let's change it!"

NO! HELL NO!! 

Please... A correct way to repair is to analyze what's that IC for and find out the reason why it becomes a problem which is our

Third Step - read the diagram


I know lots of shop in Malaysia keeping your iPhone for two months or longer and then failed to repair it. You know why? Because they can't find the real problem and the whole iPhone is already messed up by blindly changing IC.


Okay, let's open up the schematic of iPhone 7, check the location of the IC and zoom in to read the label of this IC.
It's called U2301.

You might ask where is the schematic.
You can download it here.



Once we know the name of the IC, press CTRL + F to search and type u2301. You will find this IC's diagram.
Here I'm not going to teach whole diagram reading here. I try to make this article short.
Watch the video if you are intereste
d.


From what we see in the diagram. This IC just to provide voltage to the other side.
According to what I read from this diagram, I understand this is one of the kick start systems that don't exist in the previous generation of iPhone. They called it Boost.

I'll try to explain noob version: Once the board detects the voltage is enough, this guy will make sure power stabled and pass it on to other few critical components.
Well, in every iPhone there is already have one similar IC. They added another one since iPhone 7.

So there is a high chance this guy is not the real problem.
Immediately we use a multimeter to check it's output circuit line.
How do we know where it goes out? By looking at the diagram, you will see "VOUT". Clearly, it means voltage out.
Then check those capacitors that on the bold line of VOUT.



The highlighted whole line is shorted. 


Fourth Step - How to check who is shorted in all those highlighted components?

Because there is only one component become faulty in this kind of sudden death issue.
The only way to find out is to give them exactly the voltage they need. By doing so, the real faulty component will take the heat itself.

First, we remove the IC that protecting them. Inside we make a jumper connect main voltage into this shorted line.

Remove this U2301 IC


Then solder two points with a wire. This is what we called - Jumper.
After that, connect to the power supply and start slowly supplying voltage on it. It's still showing shorted but this time would be different. Because the original source of the problem will take the heat itself.

If you don't have the camera, no problem. Use your finger.
or rosin technique.
As I said before, 99% is the capacitor problem for "Sudden death issue".
Remove it and the problem will go away.
Replace it if you want, but you might think isn't that will affect the device working properly?
It won't for this line.
Example let says the house you living have many reserve water tank, and if one of it is removed, your home would still have the water supply from outside.
Understand? Your house's continuous water supply is from outside. Not the tank.
But take note of this - Depends on the diagram and the capacitor purpose. I only explain more details in my course.

Once we removed the problem capacitor...
See? It'll still work without it and the IC but...

Final Step

We still need to solder the U2301 IC back on it though.
Because if the same problem happens on this line, it might burn a hole on the motherboard.
 
Countless irresponsible technician out there, they seem don't care. Maybe their volume of repair is low and I'm a specialist that only repair Apple, with that much of volume devices repaired... so I had encountered second-time capacitor problem that really burnt a hole. 


All memory data is not affected. Done.

iPhone 5S error 4013 | Red screen reboot loop


Recently we repaired many iPhone 5S that having this kind of problem.

  • Red screen reboot loop
  • iTunes restored error 4013

    You can force it to enter to recovery mode. But it will end up with an error 4013 in the restore process.

After I read the report of the error, found out all of them are indicated NAND failed. (means memory hard disk failed. NAND is the flash memory in iPhone motherboard)
Well, I think this kind of problem is reasonable. Especially it happened to a heavy user using it ever since 2013, it's been 6 years.

First of all, I need to clarify that Apple iPhone is good in term of lifespan.
Of course, the battery is a consumable part that needs to be replaced after two years.
BUT a lot of peoples don't know that the memory hard disk actually has its own lifetime. "Example: a computer hard disk drive becomes dead itself."

Below photo is Google is the answer to memory lifespan.

 
See for yourself, Flash storage is 5-10 years depends on the write cycle.

To repair this problem, we just have to replace the NAND memory chip. But it will be a hard job for most amateurs out there because the technician must be well trained to prevent damaging to CPU which is on the other side of NAND.

I repaired a lot of other dealer's mess. It was supposed to change NAND job but ended up to rebuilding the CPU and SDRAM. They accidentally damaged the CPU in the process, then causing their customer to raise budget or argument.

5S NAND memory
A professional like me can remove the NAND safely. No damage to NAND soldering pads and CPU.

5S nand replacement
Original 5S Nand is black, I replaced a white one on it. Why?
As I said before, memory lifespan. Must put a new one, the old Nand is black and discontinued product.

Advise:
  • Always backup your old iPhone, you never know when it became dead. 
    NAND replacement = Memory data lost
  • Send to the true professional to repair this issue.
We can also upgrade to a bigger capacity if you have a bigger budget.

iPad Memory Storage Upgrade

This is iPad Mini 4. Owner wants to upgrade to 64GB


Don't tell me you have a 16GB iPad you are still using.
If so, then it's really painful that you need to keep deleting things for space.

Regret bought the low storage iPad?
No worry, we offer iPad memory upgrade service.


We can upgrade the storage for any iPad model.

The same iPad Mini 4 upgraded to 64 GB.
iPad Storage upgrades Price List 2019 2nd Quarter:
  • 32GB - RM 200
  • 64GB - RM 330
  • 128 GB - RM 400
  • 256 GB - RM 500

FAQs:

Q: Can I still update the iOS after upgraded the storage memory?
A: Yes. It doesn't have any side effect.
Q: How long it takes?
A: iPads are not like the iPhone, which can be done on the same day. It would require 1 to 2 days. Because open iPad is not just using screwdrivers, It needs some machine to open it.

Q: What about my data?
A: It needs to be format. Means all data will need to be erased and update into the latest iOS.


Q: Why just warranty one month after the upgrade?
A: Because we never know how the user uses their iPad. Not confident in how they take care of their iPad. They can even kill it with the wrong charger also. That's why we will check all function and inspect the whole device first so that we can eliminate potential problem too. Most parents give the iPad to kids.


But don't worry, let just say unfortunately it has a problem later and 1 month is passed. We will still do the repair for you FOC.
By the way, the warranty is cover on the motherboard only. Not the screen, buttons, or camera.

Q: I have another question...
A: No problem, feel free WhatsApp to me and ask. CLICK HERE

iPhone Unable to Activate Repaired

Since the latest iOS 12 released, I see a lot of iPhone that having this problem.

Unable to Activate
Your iPhone could not be activated because the activation server cannot be reached. Try Connecting your iPhone into iTunes to activate it, or try again in a few minutes.

If this problem persists, contacts Apple Support.
It only happens on iPhone 6, 6 Plus, 6S, 6S Plus, 7, 7 Plus, 8, 8 Plus, and newer model. 

                       
It is definitely a hardware problem if the solutions below you already tried. 

  • Restore again in iTunes
  • USB cable activate with iTunes
  • Another internet or WiFi router
  • Another SIM with available Cellular Data
  • Another day (Might be server down, right?)

All methods tried and still not working? Frustrating huh? 

Are you getting this message in PC?
It actually means some information on your iPhone could not be obtained. That's the real reason, but not details enough.
  

No worry! It can be repaired. Logic board problem for sure.

Because Apple added new rules into their activation server again.

"All encypted communication chipset must be verified."
Also means if one of it failed, then it won't let you activate. 

I remember last time iOS 11, they added new rules in server to check WiFi and Bluetooth address match with Serial Number of the device. So that any modification on those would be banned and not allow to activate. Each device is using a unique address for the network component. I also believe it's a license issue too.

Back to the topic, to fix this issue. I need to open up and inspect the logicboard's network chipsets. One of its malfunction would cause this problem. Repair it then problem gone.

Easy for me, but not every technician is qualified to do so. If you're interested to learn how and why, please take our full course of Advanced iPhone Logic-Board Repair. 



iPhone unable to activate repaired
Problem solved!


Photo might be fake, huh? How about a video instead?

Damaged iPhone Data Recovery - iPhone 6 Plus Bent


 Heavy damaged iPhone 6 Plus sent in our shop...
The owner kept it many years until now found a true specialist to recover the data.
 

When the logic board bent like this, I'm sure the iPhone won't able to turn on.

In condition bent like that, most technician would tell you that the motherboard is spoiled. 
They are right.
The board might be spoiled. But the memory chip not broken, right?


Yes...
As long I see the three important IC is not broken then I can still save the memory data... or even fully repaired it. 


Let's me explain some details.

In the current era, all iPhone IC chipset (integrated circuit) are using BGA (Ball grid array).
They are bound on the board with solder balls.


Not this type anymore. So that your iPhone can be designed smaller.

The photo above is a macro shot at beside of a BGA IC that bound on the motherboard. Those are solder balls joint.

So in closer look... those IC failures because of crack.
So now you understand why I said it still can be repaired.
As long as I see a few "important" IC are not broken yet.

How to check?
I need to inspect those parts by microscope and let you know the chance of success repaired.

Your processor is also known as CPU. Without it, your data is unable to decrypt.
 Do you know there is news that the FBI is also unable to hack or bypass the passcode of suspect's iPhone.
They even ask Apple to unlock it but they decline and said it's not possible.
It's against their policy and product design.
   


And this two.


When I see these 3 parts are good condition.
All I need to do is just transplant them into a good motherboard.

So I just moved this 3 parts into a working motherboard, it should able to turn on.


After a few hours of surgical works. Done!
All data remain the same as before accident happened.
Hmm.. very old iOS. 8.3? indeed a very long time ago...
Tips:

The hardest part always is the CPU. Not many people in Malaysia can do it.

Having the equipment to repair, doesn't mean having the skill. 


Reball CPU is very complicated works.
Choose a technician to carry this job is just like choosing a doctor to open your brain or heart.

Microscope photo shot that I repaired this iPhone.
If you see those balls in your iPhone CPU, means it's been repaired before.
iPhone that no repair before is unable to see those BGA joints because Apple Black Glue sealed around it.


Someday I might write what procedures to repair the CPU. It is too many steps which normal technician couldn't do or no waste time to train on this.


They don't know what heat that won't harm the CPU.
They don't know how to remove CPU safely and not breaking its point.
They don't know how to rebuild the SDRAM because it sits on top of the CPU.
They don't know how to perfectly reball CPU hundreds of balls with balance same size.
... a lot more they don't know.

even they know.. they need to practice...
Master the heat of their machine.
Master their blade so it won't damage the CPU in the removal process.
Master the massive reball skill.
