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 👇👇

NEW VIDEO! Samsung S10 with CRAZY Water Damage

I was surprised this one was successful...

Hope you guys enjoy all the detail I provide in the videos!

FINALLY FOUND IT THEM! The Cleanroom Cloth I use for Reballing ICs

These cloths are amazing. They're soft but don't melt when you heat them.

They're perfect for reballing ICs. Just fold it in half twice & place the IC on top.

While you're reballing, the chip will sink down a bit & allow you to reball much better than if you were to reball on your workmat

Buy them here:
