I ran a snapshot of cyanogen for a while, but my phone refused to update to new versions. I got frustrated and installed the nocturnal GPE rom which worked fine for a few months, but recently would not connect to the networks. I attempted to run the factory reset command from TWRP, but the phone hung for an hour trying to erase the cache. Then when I restarted the phone, instead of seeing the boot screen for the GPE rom I had most recently installed, I saw the cyanogen boot screen.
I have had little luck reinstalling roms since then and also have some problems with the recoveries. I have to install CWM or whatever recovery I dont have installed to even get sideloading to work. I've installed the nocturnal GPE rom again, but when it gets to the screen to select English it just restarts without warning.
Right now I just want to know if it is possible to nuke everything but the bootloader and just start fresh from factory settings. I want the nightmare to be over!
I have done everything in this thread:
