You have to reflash main FW.

i tryed to flash main fw but same it hangs on Waiting acknowledge...
So i try to change phone color to brown --> cruiser says changed but when i re attach i can see its red
so i tryed to change phone color with tp... but when i changed the phone color i cant flash main fw or raw fs cause cruiser says repair erom but repairing erom impossible .. am i right?

i try all combinations but i cant get the phone alive...

v9.66 tested ..... still same problem...:eek:

all senario caught on;

The phone contains recovery certificate!
You MUST repair EROM!
Phone hardware initialized OK

Sorry, no EROM is available for this phone.

will erom for this phone be avaible soon?:confused:

flash db2010 erom browncid49

already tried;

after flashing erom;

Sony Ericsson phone detected.
Phone CID: 36
Phone color: Red
Flash certificate: A1_DB2010_36_RED
Trying Red CID36 flash applet...
Sending applet prologue...
Trying CID16 recovery applet...
All threads terminated.

cruiser cant detect phone normally so i use tp and change cert. to red49 but phone dead always...

and by the way the file with k750i extension is;
DB2010_EROMRed36_signed_by_Brown36.erom2
i flashed with that file
you are saying brown49 only file with brown49 is;
DB2010_W810_EROMBrown49_signed_by_Brown49.erom4

its for w810, thanks anyway...

I have the same problem as you.. hangs at Waiting for acknowledge and if use a testpoint says no erom available so can't repair.

Seems a problem that is spreading. Hopefully a solution is found soon :confused:
