iPad Boot Loop & Charging Issue After Repair – Now Stuck on Apple Log

Hey everyone,

I need some advice on fixing my iPad after a repair that seems to have made things worse. Here’s what happened:

1. My iPad’s digitizer FPC connector got damaged, so I took it to a repair shop.
2. The repairman "fixed" it, but after getting it back, I noticed a 3-minute boot loop issue. The iPad would restart every few minutes and wouldn’t charge properly—it showed the charging symbol but wouldn’t gain any battery.
3. I told the repair guy about the issue, and he asked me to return the next day. When I came back, my iPad was fully charged and working fine, so I took it home.
4. I used the iPad normally for over 24 hours, including charging when low and using it until low battery. Then suddenly, while at 80% battery, it turned off and restarted at 26%. After that, the boot loop started again.
5. Now, the iPad is stuck on the Apple logo and won’t boot into iOS at all.

• Boot Loop (previously 3-minute cycle, now stuck on the Apple logo

* Battery percentage jumps (e.g., 80% → 26%)

* iPad charges, but percentage doesn’t increase

* Worked fine for 24+ hours after repair, then suddenly shut down

* Now won’t boot past the Apple logo

• Loose battery connection (maybe not reconnected properly during repair)
• Battery is faulty or not calibrated properly
• Power Management IC (PMIC) issue (damaged during repair?)
• Bad soldering on the FPC connector (could be causing a short circuit)
• Corrupt iOS software (caused by power instability?)

• Force Restart (no change)
• Charging for extended periods (no real progress)
• Letting it drain completely and recharge (didn’t help)

I don’t trust the repair guy anymore, so I’m trying to diagnose the issue myself before finding a more reliable technician.

• Should I try DFU mode and restore it using iTunes/Finder?
• Could this be purely a software issue, or is it definitely hardware-related?
• If I open it up, what should I check first?

Has anyone dealt with this before? Any advice would be greatly appreciated! Thanks in advance.
