Hello, I just received my Nexus 7 (2013) this past week. Build Number LRX22G 5.0.2 came with it out of the box. I've rooted it using CF-Auto-Root and Wug Fresh. Both went flawlessly and rooted the device without problems. But, when I try and install the newest versions of TWRP or CWM, I run into problems. They install, but when I'm in either interface, it says things like E: cache or mount problems. It also says No OS found, are you sure you want to reboot, etc...I've had to re-install the image from Google (Fastboot and ADB Android SDK, platform-tools) each time to get back to stock. I've tried installing TWRP through ADB, Flashify and Wug Fresh. The reason I really want TWRP is because I want to give some customs ROMS a try, especially CM12. I don't know what I'm doing wrong and have followed tutorials/videos verbatim. Is there a way to flash CM12 without TWRP or CWM? Is it a 5.0.2 problem that other people are having? Any help would be appreciated. I guess having stock android that's rooted wouldn't be the worst thing in the world if I can't figure this out.
