This was an iPad Pro 9.7 that came in for "no power". After initial troubleshooting, we found the charging port was good, there were no shorts.
Battery was fully drained, so we boosted it up above 3.7V and we got it booting & charging... until it started bootlooping.
Once in a while, it'll fully boot again for a few min, freeze up & restart. Then goes to bootlooping, with apple logo only.
We tried a new tristar, known good parts, everything unplugged, but still all same behavior.
We also tried pressing down on the CPU to see if maybe it was CPU issue, but no change.
So i attempted an update & it failed with Error 9. But I would kick it out of recovery mode & it would go back to doing the same thing.
Since it had error 9, i figured maybe NAND issue.
I reballed NAND & BOOM! It booted & stayed on. It continued to fully function & I was able to recover their data from it.
After they received it, they confirmed it's still fully functional.
So I think it's safe to say, at least in this case, a NAND reball solved the attached panic log messages
AOP PREFETCH ABORT
and
AOP DATA ABORT
Have you ever came across this panic log?
If you have a Seek Thermal Cam, you're missing out if you don't have a VCC Seek Stand: https://www.vccboardrepairs.com/buy-seek-stand
Injured Gadgets just got these back in stock, so get them while you can!
It can take us a while to build these out sometimes, so they're sometimes out of stock for a while, but we're working towards always having inventory ready to build more as they sell out.
This stand makes using a thermal cam so easy. So much better than any other thermal solution on the market.
It allows you to get real close up (using my Macro Lens), and easily find where the short is coming from.
Plus it's hard free, so you can have your hands free to try to boot the device from DCPS, while having an image that is in focus & not moving around.
You can even record a video through the app, while you inject voltage into the short, so you can go back & see exactly which component was it that was heating up.
Save yourself lots of time by getting a Seek Cam, Stand & Macro Lens! ...
