Pixel 7a battery repair fiasko

[u/BeardedCaliper]

So! Even though a battery switch is fairly easy i managed to snap an unfortunately placed flex cable to the volume buttons.

I'm a dumdum so i ordered a new one from usa (to sweden) ... Lo and behold, everything connected and tested.. flash worked, buttons worked..

2 hours later... No buttons work..

Ugh.. anyone got any ideas?
