Nexus 7 left behind, but not forgotten!
Il Mio Problema
I was one of the many Nexus 7 tablet owners that bought the tablet from a source other than Google, and I was abandoned by Google once my tablet was soft bricked by an update. I tried like !&&* to get my tablet repaired, but no one had any clue what to do. It had been about a year and a half. Still had my tablet in a drawer, didn't get rid of it, and I'm glad I didn't. Recently did some more intensive searching online and found a post with some interesting ideas, so I decided to give this little tablet one more try. I purchased a used, but working motherboard from iFixit! And thanks to their tutorial, I'm writing this account from my Nexus 7!
La Mia Riparazione
The repair went flawlessly! I was nervous because some of the screws were so small, I didn't want to break anything. I took my time, drew a template of the area of the tablet I was working on, with all the screw locations, and that helped me keep it all straight.
Il Mio Consiglio
My only advice is to remember how Google treated us when there was a problem, and don't support a company that abandons it's customers when there's a problem. I had a Nexus 5, and this Nexus 7 tablet. Needless to say, I got rid of my Nexus 5 phone for a Samsung Galaxy phone.
