Hello list, tonight I decided to look a little at my the RAZR2 V8. It turns out that you can enter boot loader mode if you press and hold both the '*' and '#' buttons and then turn the phone on.
The screen will display: Bootloader A3.C9 (probably a version string) Battery OK OK to Program Connect USB Data Cable Connect the USB cable and the Display will show "Transfer Mode: USB". In this mode boot_usb can talk to the phone, but transfers don't seem to succeed (I just had to add the USB ID in boot_usb). boot_usb is able to upload the data, but at the end of the transfer the phone returns an error. Calling the kernel... TX: JUMPA0DE0000BA ( 02 4a 55 4d 50 1e 41 30 44 45 30 30 30 30 42 41 03) RX: ERR� ( 02 45 52 52 1e 8d 00) DONE The phone displays Critical Error: DEA1 So it is likely that the kernel has to be signed somehow in order to flash it. :-( Regards, Daniel Willmann
