Ok, I am pretty experienced with SBF'ing and such, but I have an issue here that so far I have been unable to fix. I have a couple of things I am going to try still, but wanted to get this going for other ideas. I bought a Droid X stuck at the bootloader screen. It says 30.04 ready to program so I thought a simple SBF would fix it. I have tried the .340 SBF using two different Windows 7 machines and RSDLite 4.9 with the same result. Error is 'Flash Failed ERROR: Phone: Error switching phone to BP Pass through mode" The RSD log is: "08:45:43, August 18, 2011 Line: 527 ERROR: AP Die ID: 22000201909b3a0a0000d8ff0100 08:45:43, August 18, 2011 Line: 534 ERROR: BP Die ID: 0000000000000000b55432890485 08:45:43, August 18, 2011 Line: 541 ERROR: AP Public ID: 6290a0df07eb32bbc306b1b51e5b150e239dab2c 08:45:43, August 18, 2011 Line: 548 ERROR: BP Public ID: 040000000500000002000000ffff00002d003289 08:53:19, August 18, 2011 Line: 1836 ERROR: Phone: Error switching phone to BP Pass through mode File: D:\GitProjects2\hdt_windows_flash\flash\code\flashdll\FlashOp.cpp Device ID: 0 08:53:29, August 18, 2011 Line: 719 ERROR: Phone: The "Motorola_Flash" Interface could not be found.

I get the whole error about cannot load cache/command/log which I know usually can be ignored. I have tried to flash a couple of different signed update.zip files (.340 and .596) and both fail. It just says error in update.zip after getting about halfway through the install process. Things still to try: Windows XP machine. Older version of RSD (4.7) Linux boot cd SBF ANy other ideas or suggestions? I will keep this updated as I find anything. I have done quite a bit of searching here and Google but nothing that has worked for me so far. Thanks.
