Step 6: Unplug your device, remove and re-insert the battery. Press and Hold down: "POWER + MENU + RED (End call) Keys until the "Custom recover image" screen appears
It may appear after the origonal Tmobile boot or between the android screen. If not remove the battery and try again.
Done, but this is where the process does not go further:
I press POWER+MENU+RED, the device shows first an unreadable mess (as ususal since 2.1 update), then Android screen and then T-Mobile boot screen, ending up by booting with previous version as if nothing has happened. It is only then that I leave the three buttons. I have repeated this operation many times but always with the same result: the device does not enter in Custom Recover Image screen but boots up as usual. Any idea?
I have never rooted the device nor done any other change except the 2.1 update which works normal.
The SD-card is 2 GB, the original one. I tried the operation also without the SD-Card inserted but the result is always the same.
