i am struggling with the following issue and hopefully I find somebody who could help !
After I got a new battery for my nexus, it didn't boot or charge, so I thought the battery is broken. I contacted the seller and he sent me new one. For the time in between I just had my nexus running with my old battery.
So I got the second battery for replacement from the same seller, tried it and nope - didn't boot. I figured this one would be broken again and I tried to put my originally battery back into the phone but it would not run normally now either .
It only booted up a few rare times but the touch didnt work. Since then it only vibrates shortly when I try to turn it on. Afterwards there is nothing more though. Sometimes I can see the backlight bleeding but nothing more...
I changed my screen twice before and I didn't have any problems. So technically speaking I think I knew what I had to do.
Really frustrating. If you could share your ideas with me, that would be fantastic!
