Earlier, I posted about an iPhone 13 Pro Max that had a cracked BBPMU. Replaced the IC, reballed the sandwich & we got it fully working.
Then I had a 12 Pro Max that I posted about 2 days ago. It was a strange case. I was able to get it working in the iSocket jig but not when reballed. I reballed twice & still no service.
So I finally gave in & decided to do a bottom board swap, since the issue seemed to be the bottom board. My guess is that the pressure from the iSocket Jig pressed the sandwich together & allowed it to work, but when reballed, it didn't have that pressure to make the bottom board work.
And now it works! Too bad the phone is locked, so I can test with my Tmobile sim card.
I'm just glad to get this one off my workbench. It's been stressing me out the past couple days 😅
I do want to give @Dusten04 a shoutout for his reballing video. I learned some techniques to help with the reballing of these 12/13 series. I'll post his video in the comments.
What wins have you had so far this week?

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! ...
