This iPhone 11 Pro came in recovery mode. Customer had already tried to restore it & was getting error 4041.
I had never seen this before, but was thinking maybe NAND due to the error being very close to Error 4014 & sometimes Apple changes things around with new iOS versions (16 in this case).
I tried a restore with 3u and failed at 19%, while the device would show a frozen spinning wheel on the screen, further validating my guess that it's NAND.
Replaced the 64GB NAND with a 128GB, but sadly, same results. It did not solve it.
I decided to check DCPS consumption & noticed during the restore, it was pulling +500mA, even after it had failed. This didn't look normal.
Check with thermal cam, I found PP_AVE_S1 had a short to ground. Wasn't sure what it was supposed to be, so I checked on a donor & it was .300 something, so definitely shorted.
Injecting 1V/1A to this line & found PMIC would heat up. Pulled PMIC & sure enough, short was cleared.
Then it turns out, the replacement PMIC, did not match the part# from the original. So the vendor who sold me a PMIC for iPhone 11, 11 Pro and 11 Pro max, was wrong.
343S00354 is for iPhone 11
343S00355 is for iPhone 11 Pro & Pro Max.
So always check the part# on the IC. Never trust the vendor's labels.
Anyway, replaced PMIC & the device failed at 12% on iTunes flash 😅.
Decided to try again & it flashed successfully! But no IMEI, as I was doing top board only.
Re-sandwiched it & restored one more time & we're fixed!
Too bad I don't have the iCloud info yet, so waiting on that. But all indicators point to a fully working phone
The lesson here is.. check DCPS (Dt880) consumption for any abnormal current draw, before jumping straight to NAND 😂
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! ...
Anyone who is doing game console repairs, knows how many screws you need to remove to access the motherboard.
Especially the PS5, with the 5,000 screws or so.
If you don't already have an electric screwdriver, GET ONE ASAP.
🌟 Cordless Screwdriver with T9 Bit: https://amzn.to/3E5duCj
🌟Extended T9 Bit: https://amzn.to/3c4YJac
It's rechargeable through micro USB and allows you to easily swap the tips out. You can also fold it to be straight or L shape.

This 15 Pro came in for data recovery. It came in smashed badly.
I split the sandwich & tested in the jig with a known good bottom board & all known good parts
But yet, it still restarted.
That means it had a board level issue causing it.
I found the panic log said the sensor array code was 0x80000
This was not a previously documented error code, so I had nothing to go by
Based on the backstory, I started checking everything on the board. Diode mode all the common connectors. But nothing.
Then I remembers the 14 Pros require the Gyro to work. Sure enough, rotation was not working
I found the Gyro IC & noticed it was loose
I pulled & it had some ripped pads.
Rebuilt the pads, placed the IC back & it worked! I backed up the data.
Since the Repair Wiki is not longer updateable, I will be posting the new panic logs I find on my Panic Log Cheat Sheet, only available to active members

Crazy recovery job I wrapped up this week on an iPhone 14 Pro Max that was mailed in all the way from Nebraska.
Customer told me the phone had been run over multiple times, and honestly, after opening it up, I thought this was going to end up being a no-fix. The phone was absolutely destroyed. The housing was twisted, the board was severely bent, and the damage near the NAND had me expecting the worst.
First thing I did was remove the board and inspect everything under the microscope. The bend near the NAND and CPU area was pretty extreme, which is usually a very bad sign on these newer iPhones. In many cases, once the board bends this badly, the CPU or NAND can crack internally and the data is gone for good.
Because the board was bent so severely, I couldn’t safely use my normal board heater setup to separate the sandwich board. I had to carefully use hot air instead and take my time through the entire process. Definitely one of those jobs where one wrong move could destroy the last chance at ...
