[Miscellaneous Android Development] WileyDigital:
My e739 wont boot into hboot. Originally it was rooted and s-off running CM7 (nightly) and the phone hadnt been used in over a year. I pulled it out to use it as a back up, but the phone would recognize a AT&T sim card however everything else worked just fine within the ROM. So I figure I would reload ROM. Then realized the recovery wouldnt flash any ROMS. I tried to flash a new recovery via ADB with no success. ROM manager was able to install a new recovery but I still had the same issue:

I have tried 2 different ROMs (including RUU, above) and I get nothing. Decided to take it back to stock and start over, but I couldnt get into hboot, manually or via ADB command. When I attempt it hangs on a black screen then reboots. I downloaded LG Mobile Support Tool and had it try and bring it back to stock. It was successful in upgrading but now when it boots, it bootloops on Tmobile splash screen and I still cant get into hboot. Any suggestions or thoughts?
