My computer always detects the device PIN, so I couldn't do this step as You described. Any sugestions?

i hope all this work but, i ve tried this as well.so i decided to take it to an engr. who said i will need to change the power ic but since i ve not been able to get the power ic

My Curve 8530 isn't stuck in a reboot loop..it gets to the carrier logo splash and freezes...in app loader it connects and shows the PIN, but won't finish connecting...freezes on "Read device service information"

anything else I can try?

I think you need to wipe your device at first !

my screen is completely black, when i tried using the apploader, it gives my pin but it wont erase it

i love this trewat and went throught reading all of the problems other are having and i nothing one other was having the same problem as me.
my 9550 screen is completely black, the light flashes red when battery is put back in or on the charger.
the phone work because lights on the button below are on and battery is high, becuase i checked it on another phone
and if i press the SAY A COMMAND bootton and say check battery, it reply battery is high.
a lcd/screen change did nothing for the problem.

i have done evething that i have read on this page and the 4 other more than twice...

is there anything else that MIGHT work?
