After doing hours of research, I was able to successfully get my phone rooted and TWRP installed (using the GooManager app). I had the AOKP d2vzw rom (milestone 1) downloaded and on my phone. I then tried to use GooManager to install the ROM. The phone rebooted into download mode, then gave an error message. I think I didn't properly unlock the bootloader.
After that, the phone wouldn't boot to a ROM at all. I've been trying to install stock ROMs using ODIN and was able to get the stock recovery back, but now all I can get to is the stock recovery and the Download Mode. Whenever the phone boots normally, I get the message, "System software not authorized by Verizon Wireless has been found on your phone . . ."
The biggest issue I've had is that it seem like nothing will install properly using ODIN. When trying to flash TWRP, it fails after NAND Write Start!!. When trying to flash a bootloader, it'll give a write/fail after aboot.
At this point, I'll be happy just getting it back to a working ROM. Any help would be appreciated.
