Thanks for your efforts. I have bootloader 1.04 and using ROM VzW 3.3 I got the Error: 120 message (country code) after trying to load 6.1 and now I am stuck in bootloader. Time to search that issue and clear it.
First time flashing a phone but I have done other types of devices before eg motherboards, CD/DVD burners, cameras etc. But yes I am a "newbie" here.
Current ROM VzW 3.3, BL 1.04
Update 3/8: uni_exitbootloader did not work; still reading up.
