Apple Certified Technician? ACiT

"We are Apple Certified iOS Technicians. Anyone can be one too."
Get a Tech ID and then pay $20 take and pass the SVC-19, then the Apple Certified iOS Technician (ACiT)" 
Apple Certified iOS Technician, certified by Apple. It is easy to do, open resource, and frankly--quite dumb. It's just an online exam. 

Truth about Apple Certified Technician

It's so hilarious seeing some repair shop showing this so-called ACiT Apple Certified Technician to the customers.

"Pandai cari makan."

I tell you the truth.
Even for the Apple Technician that working inside the center, they can't repair the job I do every day such as 
motherboard problem and data recovery.


One of my reason that not want to be authorized Apple Service Center because they DO NOT allow us to repair anything that beyond screwdrivers can do. Especially soldering.

They only allow screwdrivers job to replace parts. Such as Battery or LCD replacement.
If a bigger problem then needs to requests a replacement of the same model which all the memory data can't be saved.

This is not a real repair.

I'm more like "True Repair Art" instead of "Replacement Art"

In the end, I just wanted to say...
Apple Certified Technician NOT helping

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 question:
"Is it the bigger storage of the iPhone and it will be lagger (slow)?"
The answer is NO.
Because the speed is entirely up to the memory chip.
Exactly like you buying a memory SDcard that have many different brand and speed.



And the memory chip of the iPhone is called NAND flash. As I said many times before, Apple doesn't make storage. They take the supplies from Sandisk, Toshiba, Hynix, or Samsung.

I know you guys 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's iPhone run better than yours. Not only in term of speed. The cellular or network performance is also different. You never know what you bought. Different batch and location can have differences.   


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

Lower Tech = Cheaper Cost.

Below is the comparison of 32GB and 256GB NAND.
The speed test is exactly the same as the iPhone 6S with A9 CPU and running PCIe.
I can say it's under a fair test. 


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 this article short.

So 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.

Please don't think the Toshiba is slower. Other brands are also slow if they are the low capacity storage type (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 to send, loading game time decrease, transferring between PC, 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 | Unlock ID iPad


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.



Methods to Unlock Apple ID / Bypass Activation


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...

How 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 !!


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.
