I rooted my 7015A a while back and installed the android app market. All worked great for weeks. I noticed the other day that it stopped working--got the notorious "download unsuccessful" error and spent the day trying to fix it. I researched and tried all the fixes, but none of them fixed my problem. I reset the device to factory and then reloaded a "fresh" back up (the state after it was rooted and before I started goofing around with it). I installed gapps from the zip, started it, it ran the update and I tried installing apps and I still get the "download unsuccessful" error. Any suggestions?
