thanks for your help
i created my own uyda file
and flashed
well this is my experience -
"followed the guide and got an error message and the flash didn't complete and the phone stuck on "Test mode"
removed the battery and then booted the phone. luckily it wasn't bricked
downloaded and installed another version of phoenix and tried the same procedure and got the same result
then again downloaded and another version of phoenix, installed, rebooted the PC, flashed. then got the same error message again. and phone hung on "Test mode"
finally gave up and accepted the fact that this phone can not be hacked or probably there is something wrong with my PC.
installed my usual signed apps. then just randomly i tried installing "virtual key" (i had that app from my 5800, don't know why i installed it, but i did and it got installed)... then i realized that even though the phone wasn't flashed successfully, the installserver was still "implanted" in my phone
so the nutshell of this story is -
even if your phone gets flashed "unsuccessfully", just recheck, coz it may actually be flashed correctly even after getting errors, before trying to flash it again
