I used the JL_Cmder program to wipe a BB handheld we've been having problems with.
I try to now reload both the latest OS and the previous OS from BB/Nextel's site and I keep getting the following error:
A fatal error has occurred while updating your device's software. Please try again.
Unable to communicate with the radio hardware. Please ensure that a charged battery is installed in the device and try the loading operation again. [P:0x0000000F]
It gets to the part where it's trying to connect to the bootROM and then displays the above... 3rd step in App Loader...
