Okay, so I've just run into a really annoying problem with CM7. I've been using MTDEV-CM7 since it's creation. Starting yesterday I started getting the "device not compatible" error in the play store when trying to install an app. Then I noticed that nearly every app said it wasn't compatible. Even ones that were already installed on my phone. There have been times in the past that I've come across this before. A reflash always fixed it before... Before trying a reflash I tried deleting the google play data, uninstalling updates, and even clearing cache & dalvik cache. All in every combination possible. Still had the issue. So I figured reflashing was in order. I factory reset, wiped cache, wiped dalvik, and and reflashed MTDEV-CM7 10/15. To my shock, I still got the same error on google play. Couldn't install any apps. Still said my device was not compatible. Weird. Thought maybe I didn't clear my caches right or something, so I repeated making sure to factory reset, clear cache, clear david, reflash. Same result. What?? Ok... Really weird. Thought I would flash the 09/26 build and give that a shot. Factory reset, wipe cache, wipe dalvik, flash. Booted this one up. Let play store update. Okay it appeared to fix it. I installed about half of my apps all fresh from the app store. I didn't restore anything from a backup. I thought maybe something in a backup might be causing the error. After about half of my apps were installed I rebooted my phone and went to install the rest of my apps. Now the problem is back. "app not compatible with your device" for nearly every app in the play store. I started over again and reflashed the 09/26 build. Same problem. UGHHH! I also tried to choose the apps in the play store on my desktop browser and have them install to my phone. This didn't work either. Now I'm just at a loss for what to do... I am certainly no newbie to flashing these ROM's to my phone. I've literally done i hundreds of times. I've gone back and made sure I was doing each step correctly and reflashed with the results being the same. Now I'm so frustrated I just don't know what to do... The gapps I'm using is: gapps-gb-20110828-signed.zip Does anyone have any suggestions for me? This is VERY frustrating!
