very big problem...
i've upgraded to the new os v.5.0, worked with it for a while, and for some reason (mainly, the carrier can't handle that os, so there's no sms), had to downgrade..
now, i don't know exactly what i was doing, but something went completely wrong :
(1) i have a bbsak, so i did an "system wipe" through that app (it's a low-level wipe).
(2) i've installed the original os which i got from my carrier into my pc.
(3) i've deleted the vendor.xml, and clicked the apploader file in the RIM folder.
(4) nothing's happening...
right now, i'm in the application wizard, dmi, and while starting the installation, it just pauses at "connecting to the device (ARM)" and the bold goes "reload software 507".
what should i do?!?
