iPhone 6 Touch ID Repaired

A customer came with an iPhone 6 which having Touch ID not working. But home key still works.
He already made appointment with me so that i could check and repair on same day.

Below are the steps how i teach my staff to repair.
As usual, must need to opened it and put under microscope to check.

  1. Check the home button flex. 
  2. Check the FPC connector for home button / Touch ID. (iPhone 6 is J2118)
    Measure the voltage by using multimeter.
    Other pins just measure resistance.

Flex is good, no broken..
BUT THERE IS A BURNT MARK under the home button.

Found the shorted capacitor. Need to replace it.
But better find out why... So continue to measure FPC connector which supply power to the Touch ID.

Found out 1.8 is over power.
Check the iPhone 6 schematic to find which ic is supplying the 1.8.
In diagram look for keywords PP1V8_MESA_CONN. Search where it leads.

Found it. It's U2100.
From the diagram you can see U2100 job is taking 3V and cutting down it's current to 1.8V and supply into FPC.
Mean this IC is not doing his job. Need to replace it too. (Some technician will just borrow a 1.8v from another spot and jumper to here. But i prefer teach my staff to repair it as original designed)

Replaced burnt capacitor on Home button flex and U2100 on PCB. Then Touch ID is resurrected.
By just using basic resource and schematic can do the job without problem.

Old iPhone 4S Repair Board

Don't think we don't have provide repair for old iPhones.

Even you send us the oldest iPhone 2G (1st Gen)
We still can do it...

This time a customer sent in a iPhone 4S which failure attempted repair from other shop.

After a brief checked on it. Found out the previous repairer replaced the Power IC.
And the iPhone still unable to power on.

By looking carefully at the board, the other side of Power IC is CPU. This is very heat sensitive area. If an amateur technician try to replace the Power IC with incorrect temperature or method, it will cause CPU problem. CPU problem will cause iPhone unable to boot up.

A5 SD RAM cracked
There is a cracked line on top CPU. Usually it happened because of other side too hot and this side CPU bloated
This A5 is iPhone 4S CPU. Actually CPU was below this A5. The Apple logo with A5 part is SD RAM which sitting on CPU.
Means there is two layer for this IC. 

So the problem is this top of CPU cracked and bloated. 
All i need to do is replace the SD RAM.

Honestly to tell you that iPhone 4S doesn't worth to repair since Apple stop giving new iOS on it. Unless you have some important data need to recover.

Yes.. This customer do have important data must need to backup. We quote him RM 250 to repair. Market value of iPhone 4S is about RM350 - RM450. 
It's consider fair price to him and me (worth of my time)

So we remove the SDram from our working iPhone 4S then reball it. Left is the one reballed.

Ready to mount on top of CPU. 

Done. Lucky all the data still remain. 
Forgot take picture. But we care customer privacy so usually we don't take photo of inside.
Happy customer collected this iPhone on same day. :)

How to read battery health and original?

Most user upgraded to latest iOS 11.3 or newer.
Inside come with new feature which is about reading battery health.

If your battery doesn't show maximum capacity, then you might have battery problem or either it's not original.

If below 70% is consider very weak. Should replace it.

However, it's best to use third party PC app to read the capacity and how many times it been charged cycle. 

Photo above is Chinese app which i forgot switch to English. Sorry.

It show this iPhone been charged cycle 707 times.
56% is battery health.

1587 mAh is the current maximum battery capacity it can hold.
2855 mAh is original designed max capacity.

In new iOS battery health check, you can only see battery health percentage. And it's not so details as PC app.

You never know the battery you replace on it is how new and actual capacity. If "they" put high grade battery, you won't know with this BETA of iOS battery health check.
(A low grade battery won't show maximum capacity.)

So the best way for end user to check is to download third party PC app to read it.
We are using iTool.

Photo above is the original battery that we replaced.
Since the new battery hasn't been fully charge, so it's 0 times cycle.
Health 100% (Health will become 99% if charged to full once)

As you can see. The battery current condition can hold 2865 mAh. Slightly higher than original design 2855 mAh. 
(It's normal since battery is made by chemical. So it would be + - 5% from factory designed.)

A high quality grade A battery usually between 2300-2600 only. 

Note: Even you bought new iPhone that come out from box freshly, it might be just 99% health and capacity is slightly lower or higher 5%

Read here if you looking for higher capacity battery:
From what we found in market so far, those higher capacity battery is scam. I have so many customer cheated by those. 
Higher capacity battery won't exist for Apple iPhone. Because Apple lab spent so much money to design the whole iPhone with maximum battery space and life. Who can beat their own product? Unless that someone has special technology which is unique and created by billion cost lab. And they selling those to you at cheap price? 

Replace your battery today while it's still under Apple offer this year. We always have stock to replace it just within 15 minutes.

iPhone 8 Home button Touch ID cracked

Yesterday a customer asked iPhone 8 home button repair.

We been repaired many home button with Touch ID for older models. But none of those are cracked on surface. Most of them are ribbon flex broken, or either water damaged which still success repaired.

If your case is like photo at below...

iPhone 8 Home button cracked
Surface of button is still possible to repair if Touch ID not fail.
If unable to record new finger print, then you are unlucky. The sensor surface is completely damaged and now so far there is no way to repair it. (Apr 2018)
  • Touch ID surface cracked - Can record new finger print - Can repair.

  • Touch ID surface cracked - unable to record finger print - Can't repair

  • Touch ID flex broken - Can repair as long you keep the original

  • Home button not working and Touch ID works - Can repair

  • Home button works and Touch ID not - Can repair if it's original button.
*If iPhone 7 or iPhone 8 Home button has problem, the iphone usually take longer time to boot up.

iPhone 5S Screen popping out

Many customers came here and asked how much to repair the screen.
This is consider very harmful to LCD screen..
The gap is getting wider day by day..

But we told them is not the screen problem. It's the battery bloated and pushing the screen out.
So by changing the battery, then the screen can be fit back.

There is some stickers on there. I believe he replaced it before..

Left old battery, right new battery

Lucky that LCD screen is working perfectly.

Closed the gap. This device can last another year again :)

iPhone 6 Water Damaged Repair

You should read this before you send water damaged iPhone to repair..

In our shop, we will open up and look how serious the damaged then we tell customer how long time we need to clean and check.
Yes.. just check only. Then we quote a price BEFORE repair.

What to do if your iPhone get water damaged accidentally?

  1. Turn off the iPhone if it's still on
  2. Do not try to charge it. (You might create more damage to board components by charging it)
  3. Try to dry it. Hair dryer can do the job. Don't worry about the heat. Blow on behind housing. Not the screen. If blowing on top of screen, LCD might get damage if too hot.
  4. Try to turn it on after cool down from drying process. 
  5. Still no luck? Then you have to send it for repair. As soon as possible. 
  6. Can turn on and everything works fine? Advise send to our shop for proper clean that prevent further corrosion damage.
DO NOT PUT INTO RICE. IT DOESN'T HELP. Use whatever method to dry it instead of letting rice to absorb it.

Below the is case if you didn't do proper cleaning and not soon enough.

iPhone 6 water damaged metal shield

We will remove all the shield and expose all the ic / chipsets to clean it. With proper cleaning PCB alcohol and machine.

  • Most of amateur technician didn't remove the shield to clean, because they don't know how to remove the metal shield and put back. After they cleaned only the surface and manage to turn on, it might appear more problem later.
Owner didn't send to repair at once. Corrosion growing all over around important components. Blame the rice myth.

After took all the shield off, you can see how bad water can be done on the component. 

This was the job done by outside shop. They didn't remove the metal shield, so there was still corrosion around the Baseband PMU. This problem is causing No Service and Searching for network.

This iPhone 6 has been sent to other shop before our hand. Owner paid RM200 for them to repair the water damaged. It was working for few days, after that he got problem with network and sent back to them but they end up couldn't repair it. They didn't refund!!

We opened up and found out they haven't done cleaning properly. This damage we need to quote a Network ICs repair and cleaning service.

Display IC corrosion. Owner is lucky that this iPhone still displaying fine. Pretty sure it will fail later if i leave it alone.

We have to make sure no other problem appear later. Found out display IC was also got corrosion and it's on the way to hell. We better replace it to prevent display problem later. Need to charge display IC repair too.

This won't be end up expensive repair if send to right place at first. Usually IC repairing can be avoid if done a full cleaning. Of course need to repair as soon as p
ossible, don't miss the soonest timing.

iPhone water damaged and the it's still can turn on? Recommend to let us do the cleaning job for just RM80.

iPhone 7 Plus Camera glass broken

iPhone 7 plus camera glass replacement
iPhone 7 Plus Camera glass replacement

We done a lot iPhone 7 Plus camera glass replacement..  but not many for iPhone 7. I guess it's design fault.

The part might be cheap. But workmanship we need to charge higher. Because we have to guarantee won't cause any damage in the process.

Story: One time there was a dealer nearby accidentally damaged the screen in the process, then he needs customer to pay for LCD screen in order the iPhone works again. They argued and ended up customer bring it to our shop repair.. 

Case like this won't happen in our shop. Usually we completed the job without damaging other function. But let say if we really accidentally damaged something, we pay for it, not customer. 

We need to go through all these parts. Make sure all screws put back exactly same spot. 

Before we process this kind of repair, we must test all the function. Make sure the iPhone all working correctly. Anything happen in the process, we need to bear the consequence.

iPhone 7 Plus camera glass repair
Done. Test all function again..

Bunch of iPhone 6S error 6

In this one week, we already got four case of iPhone 6S that having error 6 restore failed in iTunes.

the other two are repaired and collected.. 

Four 6S customers have one thing in common. They didn't buy from Apple Store. Two refurbished by Apple, other two are third party with Grade A housing.

Two of them are not bought as new. It's refurbished by third party. Housing is not original. HDD been upgraded from 16GB to 64GB.
I suspect it's the new iOS update killed their nand HDD. Because some people their upgrade method are missing something and wasn't complete. Now the new IOS 11.3 or 11.2.x will verify few more things and  then block these suspicious iPhone. But we still able to repair it and avoid the same problem again.

Other two, their 6S been failed to repair before. Then send to our place. Lot of missing parts, some screws, wifi and gps antenna, lcd metal cover, even LCD is not working.
So this two end up with very expensive price to repair.
This two 6S suffer heavy drop damaged before. Problem only appear when he upgrade iOS.

iPhone 6s restore error 6 nand
When the problem started, it's just having Apple logo reboot loop. When try to restore, it will failed like this. Error 6. Then every time turn on, Apple logo then blank and stuck into DFU mode.
If you having this problem, be sure send into right place for repair. Amateur only causing more damage on it.

iPhone 7 Plus Screen replacement

All working fine except cracked on top

iPhone 7 Plus screen broken
Screen broken or glass cracked? Little cracked on ear speaker area

Done. Color, pixel and touch sensitive completely the same.

Good as new!

Just now we done one repair iPhone7 Plus screen and i just found out customer don't know much about screen repairing and why there are so many different price out there

In today topic we share to you all about screen repairing information. You are in right place if you are surveying option to repair/replace any model iPhone screen.

Before you repair the screen, then you should read this.

Two methods in the market.

Method 1
Replace the whole LCD panel which come with glass and touch digitizer.
Very easy to repairer. By just using screw drivers to complete the job.

Usually you see outside dealer offering REPAIR WITHIN 30 MIN.  QUICK JOB.
This is their method to repair your screen.

but BEWARE, there are few option for LCD also.
I list down those keywords that Malaysia dealer usually say.

Original - Everything color, touch sensitive, glass material which is gorilla glass that hard to scratch.

OEM - This is very confusing me, since OEM stand for Original Equipment Manufacture. Mean it's still original. But i don't know since when, the Malaysia dealers saying OEM parts mean high quality, not ori. In computer world, OEM mean parts ori that without box, not sell in a good packing box or not mean for sell at retails.

So i would add another.

OEM Grade A - A very high quality compatible part that can match up with OEM. But in our Shop, OEM parts we sell are still Original Parts but it's been refurbished, renew, recondition. LCD and tocuh still the same, but glass been replaced or polished as new. 

NOT ORIGINAL - A low quality compatible screen made by unknown manufacture. Touch sensitive is effected (Very noticeable if you gaming with iPhone). Pixel should be the same in recently 2018. Color is slightly darker or brightness not so great as original.
Also is the most problematic one.
Might burn your display IC, end up no matter what LCD you put in, it won't display anything, just blank, and computer still can detect or phone still can ring. (If you have this issue, send to us)

SECOND HAND - Used parts that disassembled from other iPhone.

Method 2
Replace the glass only.
Cheaper than replacing an original LCD.
But only can do this if your LCD display still ok and the touch no problem.

LCD and touch sensitive will not be effected since the glass is outer layer which can be separate cut by special machine. Next step clean all glue and pieces, then apply the glass by another machine. Last step is put into a machine that vacuum out the air bubble that still stuck between glass and LCD.

This is very time consuming that estimate work 2 to 3 hours between. If the dealer said 30 min or less, i'm sure he replaces the whole LCD. Why not use your own lcd if it's still fine? LCD also have life time, be sure using your own one.

iPhone 7 Plus display issue
If display got problem, can't do glass change. Need replace the LCD 

Why not put the tools out front? Unless they don't have the skill or machine.

iPhone SE From Pahang Customer

Got a call on Sunday noon. He asked for urgent repair of his iPhone SE. He came from very far and needs to go back. Expect me to repair his iPhone SE which been sent into Apple Center and failed to repair.

This Customer said: My iPhone suddenly off and unable to turn on. Never drop it or water damaged. Been sent to Apple Center, they told me is logicboard problem. They can only offer me a replacement of whole device, but i need my data! Hope you can save my data. I don't care about the god damn warranty.
And i been to few repair shop, they tried with new battery and still the same. 

Recently keep taking a lot iPhone 5 SE repair. Most of them are are logic board problem which is shorted itself with no reason. I can't say is design fault, it's more likely component not lasting or quality issue.

Ok, should be easy job. Let's start. 

A proper way to check is
  1. Unplug the battery, connect the iPhone into Adjustable Power Supply. 
  2. Prepare to read how much power the iPhone is drawing from power supply. Just look at Amp meter.
  3. Slowly raise the voltage.
    In normal working condition of iPhone SE, when we adding the voltage, the Amp meter should not having motion that showing the iPhone is drawing power. Since we didn't press turn on, it should stay 0.
    Proceed to step 4 if OK
  4. Stop at 3.7 - 4.0v which is battery level. Finally, press one time at the power button to see how it reacted by reading Power Supply Amp Meter.
    Press one time for self check. Normal condition : 0-100mA then drop back to 0.
    If Ok, then Hold 2 sec longer to turn on. 
So now you know only the amateur put in new battery to check your iPhone.

We just don't simple put on new battery and try turn it on. It might do more harm if something is shorted inside. Power Supply is the most basic repair tool needed.

Shorted.. IC or capacitor? let's hunt.
Confirm something shorted.
  1. Test his LCD screen with our working iPhone. Make sure it's working and no more add up price after we done repair the logicboard. 
  2. Quote an exact price and how long time we need to repair it. (In this case, i told him one hour)

UMT board, oh shit...
This iPhone SE everything in so new condition. No scratch, no dent mark, no trace of water damaged.
Hopefully it's not the board inside copper layer problem. I wonder who was the manufacture of this iPhone SE.
UMT, uh oh...  Why it's so bad? I'm not telling the story today. :p

Put some dry flux powder, connect Power Supply and turn. Found you!

30 minutes later, customer return with drinks to watch our repair process. Voila, he is surprise that we already done repair and testing all function by calling his phone.
