iPhone XR came in for no power.
After prompt to boot, I saw it jumped and hung at ~500mA. After removing the CPU shield, I found Hydra was lighting up under the Thermal Cam.
Since Hydra is pressed up against the CPU, it's a super risky job, because it's also underfilled.
So i made an oopsies... i ripped 3 pads under Hydra. I wish i would have taken more pics, but i was able to dig out the traces of those pads & run jumpers.
Then I installed tristar & now it hung at 200mA. Once again, I checked with thermal cam & found the chip next to it was shorted. Looking closer, I see where I nicked the IC & damaged it.
It's U6150 which it looks like it's called Gecko.
I pulled that IC and ripped another pad lol. What luck.
I was able to dig out that trace as well & ran the jumper.
I was able to find a replacement Gecko from an XS board, since it's not underfilled and installed it.
Now this XR is fully fixed!
Check out all the pics for reference.
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.

Hey guys! I'm so glad to finally get here. Thank you Jesse for the encouragement. Took me a minute but I'm here. I'm so eager to learn and grow. I have some experience with soldering etc, I can treat with obvious issues but there's something about diagnosing issues (especially with iPhones) that I have trouble with. I'm hoping this community can help with that.
Currently I have two iPhone 13 devices that need repair. One is stuck in recovery mode. A flash was attempted but there was an error during the process (Error 4013).
The other 13 does not boot or charge. It pulls 0.02A on the ammeter and I can feel both the back getting really hot. I tried this with two batteries. I also noticed that the wireless charging IC also gets very hot (338S00817) even when using a wired charger.
Remember I'm a noob so please....be gentle. Any help greatly appreciated. Thanks in advance!
A funny example of why board repair are still very human skills.
Someone posted in my Facebook group asking for help identifying a ripped pad on a PS5 fan connector. The connector had been torn off the board, and they wanted to know what signal the missing middle pad belonged to so they could run a jumper.
A commenter decided to let AI handle it.
They fed the photo into ChatGPT and got back a nice-looking annotated diagram showing all the pin functions. The problem?
It was completely wrong.
The AI labeled the missing pad as the TACH signal when in reality that pad is ground.
The scary part is that if you didn't already know the answer, the diagram looks convincing. It has arrows, labels, colors, callouts, and all the confidence in the world. Yet it still gave bad information that could send someone down the wrong path.
This is one of the reasons I don't lose sleep over AI replacing board repair technicians.
AI is incredibly good at summarizing information that already exists publicly. But in...
Had an interesting iPhone 16 Pro Max data recovery come in and wanted to see if anyone else has experienced this....
The phone came in heavily smashed and completely dead. After troubleshooting, I found a VDD_MAIN short. Once I cleared the short, I was able to get the phone booting again.
My original plan was to connect it to a PC and see if I could get the usual Stolen Device Protection prompt so I could proceed with the recovery. However, the phone wouldn't establish a USB connection.
After troubleshooting further, I eventually discovered the board had a sandwich separation issue, which explained why USB wasn't working.
Before digging into the sandwich repair, I started playing around with Stolen Device Protection just to see what would happen.
I noticed Stolen Device Protection was definitely enabled. Out of curiosity, I tapped "Set Up Alternate Appearance." Normally I'd expect it to immediately reject me since I'm obviously not the owner, but instead it actually looked like it wanted to proceed ...
