I'm getting an error when I try to install BB 0.6.2.1 and I haven't seen anything similar. First of all I have a rooted DX running android 2.2.1 and stock kernel. After going into bootstrap, creating a backup wiping data and cache (2-3x each) I tried to install. Here's what I see on screen:
Installing System Files...
Symlinks and Permissions...
Flashing 800 MHz kernel...
assert failed: write_raw_image("/tmp/boot,img","boot")
E: Error in /sdard/FRG83DV0621.zip
I should I also note that I downloaded the zip onto my computer and then transferred to ROOT of SDCARD with USB.
Thanks for your help.
