Tried to upgrade to 175 tonight. Error occured during "Erasing Applications" Now I have a black/off screen, and a double flashing red LED. JLcmdr does not even show the blackberry to attempt a total wipe. HELP
Remove the battery for 30 seconds or so and replace it. While you are at it, if you have a micro SD card in the blackberry, remove it. Does the screen come on to display something, even a 507 error (hopefully).
If you just winged it with JL_CMDER and haven't looked at the FAQ linked at the top of the forum, take a look at
