Ipad mini is stucking at apple logo with some digitizers

I had 6 ipad mini digitizer replacements with 6 success. I purchased the glass and digitizers wihout ic and home button flex. I am doing soldering under microscope. I have lot of experience about soldering. So first 6 repairs done with success. But 7th ended with disaster. Back light was gone since i didnt remove battery while disconnecting the LCD.

Ifixit answers helped me to fix backlight. I soldered the backlight fuse.

I have the backlight back.

But i figured out i have different problems to answer now.

I have 4 different digitizers in stock which is soldered by myself and tested previously on other ipad mini with positive results. Now if i use 2 of them on this particular ipad mini (backlight repaired one) it doesnt pass apple logo. It shuts down. The other 2 digitizer passes apple logo Works good on touch but acts weird after 1 minute especially when i try to close to frame.


1- why some digitizers (or ICs) doesnt pass apple logo and shuts down. Any similar experience.

2- does any short on ic soldering or home button soldering damage digitizer or ic. Is resoldering ok or i need a new digitizer and new IC.

3- why home button flex has 8 points solder. I know first one is ground and 2nd one is actual home button point. What are the rest functioning ? Is it doing anything on touch.

4- why my previously tested 4 digitizers failed on my last repair. Are there different ICs. Or different home button flex cables. Different type of ipad minis. Or different quality digitizers ? Any experience ?

7th repair failed. After 6 success. Customer is waiting for 1 week. I finally ordered a new digitizer whole assembly. Waiting for it and for your answers.

I dont want to quit reusing resoldering digitizer ICs..... Thanks

I think the problem might be in the OS.

You are apparently off to a normal start in the EFI stage but then something fails… what that might be is the "HD" could be damaged, or, more likely a damaged/corrupt OS.

Of late many macbook automagic shutdowns/white or black screens trace back to corrupted OS.

Try swapping the "HD" from one of the normal booting machines.

If this answer is acceptable please remember to return and mark it.

Unfortunately there is no HD in ipad mini. I dont think it has corrupted os since it is working fine with some digitizers.


Well it's not a HD perse with platters (it's a chip) but it performs the same function, I figure you're skilled enough to swap that component too. From what you seem to be saying the digitizers check out… that leaves a corrupt file in the OS as cause of the failure. Swapping the OS (chip) would confirm or deny that theory.
