Like an idiot, I accepted an OTA (4.4.2) while rooted with a custom recovery (Philz). I got stuck in a boot loop and proceded to run through the instructions here
(method 2) to get back to stock. I have tried several iterations of this using different stock images with the same result, I can't mount /cache or /data. In the end my phone tries to boot, but gets past the unlocked bootloader screen and flashes the android laying on its back with error written below. My bootloader is 30.B2. Oh yeah, I even tried to download an experimental Cyanogenmod and install it using the ADB sideload, but it failed because it could not access /data.
Any help would be greatly appreciated.
