Nintendo Switch - Stuck in RCM Mode

This Switch came in for a damaged charging port. But I found it had some minor liquid damage across the board.

I cleaned it up with some iso & toothbrush & continued with the charging port replacement.

Replaced the port & saw it charging at 15V but only 0.5A

The battery was at 3.7V, so it should boot, but no image nor backlight on the screen.

I connected it to the PC and saw it was stuck in RCM mode.

To me, RCM mode sounds a lot like DFU mode on iPhones. And knowing how DFU mode works on iPhones, I figured the issue must be related to the NAND.

Upon further inspection, I found the NAND daughterboard had some corroded lines.

I scraped them out & diode mode on the traces near the NAND. Since those traces connect to the NAND, I should get a DM reading on them & I did. But after flipping the board over, the same line was OL.

This was a clear sign that the connections have been severed.

I ran the jumpers to the other side & that made the device boot & it was ready to go!

Check out all the pics for reference.

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.

🌟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.

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:
