I am running LGB .V7 without any issues. Today I started seeing a single black line left to right. I tried a program that flashes color at the pixels but to no availe. I called tech support at Verizon and they mentioned doing a factory reset. Not sure I can do that... so I reflashed Liberty .V7. Verizon mentioned that with my warrenty the screen was covered and to bring it back in. If I need to do that do I just SBF to 340....do the OTA update and they would not know I had been rooted? If SBFing from LGB to 340 is not correct, please let me know the best route.
