Nexus 7 2013 is stuck on Google screen. i just had and when i first booted it fooling around with a custom rom(cyanogenmod) that for some reason did not have android market/google play store. I then decided i wanted to return it to stock and at first for some reason I have a MAJOR hassle with downloading the drivers. Reguardless of the drivers the nexus 7 either becomes unknown device, other, or Android Phone. I have downloaded them from source, mirrors, Wugs,Nexus toolkit. Whenever i even attempt anything with Wugs Kit, it just says some error about ADB and if not that Fast boot. I tried installing fastboot and ABD and also tried this application called Minimal ADB and Fastboot but got similar results. I attempted it to restore to stock rom with MANY different types of tutorials including copying and pasting then to cmd and use the "flash-all.bat" command. All it would ever do is crash whenever it got to fastboot.exe. Also there is another issue with Android SDK when i attempted to use it to resolve this. It was just very confusing on how it operated because i did not understand the directions as well as the driver issue. I also attempted Unified Android Toolkit but it could not recognize my Nexus 7 as a device (driver problem again).This is very VERY frustrating because it will not work for me. i just want to get my nexus back to stock then root again without a custom rom. For some reason my computer recognizes it as an android phone and will not let it register as anything else even with correct build file. i can no longer access usb debugging because in one of the many tutorials it said to: clear cache. divalk cache, wipe data, format data, format system, etc. you get the point. I have NO IDEA how to fix this i have been at this for at least 6 hours straight. Please can somebody help me resolve this i do not know what to do anymore and it is VERY important that i get this fixed. It is really stressing me out.
