This iPhone X came in for no power. At the initial inspection, I noticed that the whole housing inside was rusted out.
Then I noticed the sandwich was already separated.
Looking under the microscope, there had been a tech already in here working on it. There were a ton a capacitors that were removed from the board.
I noticed there was a partial short, pulling about 150mA before prompt to boot. Checking with my Seek, the heat was coming from under the shield next to NAND.
Removed the shield & noticed Acorn (U5600) was corroded, along with the ARC IC U5100.
Removed both since they're not needed for booting (for now) and short was gone.... but the phone was stuck in DFU mode.
Since this was an intel iPhone that's actually normal with top board only.
Since I wasn't sure if it was truly ready to boot, I decided to try an update.
It failed. It was like 11%, which is usually a bad sign. I tried iTunes flash, but forgot what code I got. But it seemed like a CPU issue at that point.
I checked with customer about attempting a CPU swap & customer approved.
So I went for it.
It took me maybe 2-3hrs in total to complete it, but it was successful.
I also ripped a pad, which was for Racer (touch), which I was able to rebuild the pad & get a Diode Mode reading back afterwards.
So stoked this was a win!
(and yes, the customer did just have about 5GB of data on the phone 🤷♂️ lol)
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.

Stop Guessing at iPhone Panic Logs
Panic logs can provide valuable information about why an iPhone is restarting, but identifying the actual cause is not always straightforward.
A panic log may point toward a charging-port assembly, proximity sensor, power circuit, missing sensor, damaged flex cable, or a board-level issue. The difficult part is knowing which component is responsible on each particular iPhone model.
That is why I created the VCC Panic Log Cheat Sheet.
Personally Tested and Verified Solutions
This is not a generic list copied from forums or collected from unverified posts.
The cheat sheet is based on panic logs and solutions I have personally tested and verified while repairing iPhones at VCC Board Repairs. It covers virtually every iPhone model and documents the parts, sensors, flex cables, and circuits commonly associated with specific panic strings and numerical values.
The goal is simple: help repair technicians diagnose restart issues faster and avoid wasting time or money replacing the wrong parts.

In case you haven't heard, I will be moving from Las Vegas, NV to Star, ID.
In my Las Vegas office, I had fully custom built workbenches for myself & my employee(s). But now it's time to go & tear everything down.
I'm really sad since these benches felt like the perfect layout! Or maybe I just got used to them.
I've attached some pics of what it looked like before & now that's all gone.
I do have some good news tho.... I recorded a detailed video of my office for youtube! I'll be posting that video soon!
Like this post if you want to see that video!
