My iPhone starts rebooting after 20-30 minutes or use after restoring its IOS every time.

Its battery health is 91%

I ordered a set of Logic Board and Touch ID for my iPhone 6s from China (AliExpress)

It worked for about 25-26 days perfectly without any problem.

After these days it started rebooting and getting stuck on Apple Logo.

To fix this I even tried to restore its IOS (11.4).

After restoration iPhone started and worked for 2 hours initially.

After that same problem again.

It is not even jailbroken.

1 day I was trying to solve this issue and I got an error while restoring it (Error Code 2009 on PC and 4014 on my MacBook Pro) both errors were on iTunes.

after that I tried to restore it using 3U Tools.

It successfully restored and worked for 2 days but after that same problem started of rebooting and getting stuck on Apple Logo.

1 day I opened my iPhone and checked the Logic Board and I found it was Water Damaged from Circuit area where Audio IC, 338S00120 Power Management IC, etc are present

I Cleaned it Properly using Alcohol and give some it some heat at that particular Circuit using a heat gun.

And after that I tried to restore my iPhone and it Success Fully restored and worked perfectly for 4 days now.

But again now it is showing same problem and this time it shows error 9 once on my MacBook Pro but after that I used 3U Tools and restored it and again tried to restore it using iTunes using my MacBook Pro and this time no error while restoring but that old rebooting and Apple Logo Stuck problem is still here.

I am very much frustrated now of this.

Can anyone please help me to solve this problem permanently.

Thank You!

Best Regards!

If I understand correctly, both the original and the replacement logic board have the same reboot issue?

If that is the case, then something other than the logic board is causing this issue. If you have already tried a new battery, then try disconnecting only one peripheral at a time, like the cameras, sensors, lightning port. If the phone starts working properly with one component removed, then you will have found the culprit.

No Sir,

Its original logic board is iCloud locked, there is no other problem in that logic board!

Hello,

I would say you have to try it in a different housing, even with a different home button, to make sure nothing is causing this issue and it is indeed a board level failure.

In which case you will have to have it replaced from the seller, if that is an option.

Otherwise, a micro-soldering technician might be able to repair it for you. Occasional boot-looping is tricky but I have successfully diagnosed and repaired a few and have a pretty good idea what may be causing this, if it is indeed at board level - just saying it can be fixed but is definitely not a DIY repair, as it may require something like Codec chip re-balling or replacement.

Thank You Sir,

Firstly I will try to return it to the seller and get a new one!

It it is not possible then I will surely get it to a micro-soldering technician!
