Lifted Solder Pad

[olevonpopole]

Hi, I tried to install the Instinct NX modchip today and unfortunately lifted point D. Do you have any idea if I can still save it. I get very strange readings in diode mode as seen in the picture. Thanks for any advice

it's saveable but it's not an easy job. you need to reconnect the trace (visible copper close to the apu) with the via (in the middle of the pad/hole that is missing)

I tried but the hole takes no solder. Maybe with solder paste and hot air?

There is also a big chance of shorting because there is ground all around.

Guess my only real chance is reballing the emmc and solder a wire directly to the trace

Are you using flux?

Yes i do. But i feels like it doesn’t help at all here. The 1.1V reading i got is also strange, there should be no signal at all

take to a repair shop, that need a steady hand and knowledge, if you keep trying you will make it worst.

You need to fix the via either way. Right now the clk connection between apu and emmc is severed and your switch is dead.

Edit: I may have misunderstood. Either way, reballing and connecting a wire to CLK under the emmc is very difficult since the clk ball is on the inner side of other balls. You'll probably want to get a green MITM adapter. There are some people in the picofly thread who make custom ones, might be worth having a look
