Hacking Feedback I fucked up my brother's switch

Hi

I wanted to install a mod chip on the v2 switch my brother was using. After disassembling, wiping off the thermal paste and turning on the switch, a blue screen appears.
Under the microscope, I can't see any damage caused by the cleaning.

Could you help me with this?

Why would you remove the heat sink, and thermal paste, then turn it on? Maybe you overheated, burnt up the chip.

A blue screen can be caused by a variety of things, including bga issue on soc, bad ram, bad emmc or even bad m92t chip.

I'd say start with the easiest one, unplug and reinstall the emmc module, it might got loose during the disassembly (although unlikely as it's glued to the metal shield underneath)

Also check traces near the cpu/ram shield, they might get damaged when you try to pry it off. Hope you didn't force it off as you'll bend the motherboard and might cause bga issues.

As for the heatsink it doesn't really matter, the soc barely gets hot when in bootloader/booting the system. I do it all the time after installing modchips, just plug in the battery/vol buttons and screen and do a test boot, see if it can train properly and boot to ofw

First, I need to buy an air gun. I'll try it, thank you so much

Learn the difference. An 'air gun' is a firearm, I think what you meant was a 'hot air station'.

You've probably overheated one or two things after you removed the heatsink or shorted out something. Leave everything to a professional if you cannot be confident fixing it up.
