How I got the data from this overheating S22 Ultra

This came in for No Power.

After checking the battery voltage, I noticed the battery was fully dead, hence, it wouldn't boot. It was reading 0V.

I manually charged it with my DCPS by injecting 4.2V/2A into it until i reached above 3.2V

Afterwards, I plugged it into the charger & waited for the phone to charge it. After a few minutes, I noticed it was giving me a red triangle and it would stop charging.

But it was enough to power on.

I then noticed it would right away shut down after getting a message about overheating.

Physically, the phone was getting hot. I checked with the thermal cam & found no obvious component, like a shorted cap or IC, causing the heat. I just saw general heat that was possibly coming from inside the sandwich.

After, I realized that if i didn't plug in the charger, the phone wouldn't overheat or restart. Only when plugging in the charger.

So that lead to me to figure out a way to externally charge the battery, while it was connected to the board. This way, the phone will stay on & allow me to pull data wirelessly via WiFi.

I decided to get the Sunshine External Battery charger, since that will properly regulate the voltage & not risk overcharging the battery if i were to manually do it.

I decided to use the + and - from the iPad battery connector board for the Sunshine charger. I used 2 wires to solder directly to the battery connector flex.

Then I plugged in the Sunshine charger to charge the battery, while the device was booted.

Then I connected the phone to my PC via DEX. This allowed me to connect the phone to my PC & control it. I then connected the phone to my NAS server, so I can copy all the files the customer needed.

This took several hours to copy but was successful.

There was a ton of troubleshooting time that I spent on this, but this is the general high level process i took to get the data.

I hope you enjoyed this one!

Which Thermal Cam Do You Have?

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! ...

If you do consoles, you need this.

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.

Let me know below if you are already using an electric screwdriver 👇👇

iPhone 16 Pro Max – Hidden Board Crack (No Power → Data Recovery Case)

This one came in as a no power data recovery job. Customer said it died overnight, no prior damage, and Apple told them the board was done and data wasn’t recoverable.

Physically, the phone looks clean. No bends, no cracks, nothing obvious. I’m honestly not sure how the board ended up cracked, there’s no visible external damage that would typically cause this.

Here’s what I found 👇

Initial testing:

  • Able to boot with minimal setup (board + screen + battery + charge port)
  • Stuck at 5V, very low current draw (not charging)
  • No touch response
  • Boot current draw looked normal

Direction I took:

  • Focused on the touch issue first (since no touch = no data access)
  • Using an LCD aftermarket screen:
    • Got image
    • Still no touch
  • OEM/OLED behavior pointed toward a board-level display/touch issue

What I found:

  • While removing the shield over the display IC… found a board crack
  • Several display connector pins reading OL (open line)
  • Traces route from connector → PMIC / display IC ...
Can you spot the problem?

This is an iPad 10 that came in for No Image/No Backlight.

Within seconds of removing the shield, I saw the problem.

Can you? I'll post the close up shot later today in the comments 👀

Would You Be Interested in Private Repair Livestreams for VIP Members? (Vote on this)

I’m thinking about adding another perk for the paid members here in the community: private repair livestreams where we work through repairs and troubleshooting together.

The idea would be to do members-only livestreams where I could:

• Work on real board-level repairs live
• Walk through my troubleshooting process
• Interpret panic logs together
• Answer repair questions from members
• Talk through CPU swaps, tools, and techniques
• Explain why certain failures happen

It would basically be a more interactive way to learn, where you could ask questions while the repair is happening.

Before I start scheduling these, I want to gauge interest.

If you are a free follower:
👍 Please like this post if livestreams like this would interest you.

If you are a paid member:
💬 Please comment below if you'd like to see this and how often you'd want them (weekly, monthly, etc.).

If enough people are interested, I’ll start planning the first livestream. 🔧📱
