Android 2.3.3
Baseband 12.56.60.25U_26-10.04.03_M
Buildnummer 2.42.161.2
Softwarenummer 2.42.161.2
with this Guide http://forum.xda-developers.com/showthread.php?t=1178912
It works very well, but the last point doesn't work

CID incorrect! update failed!

Thanks

i dont know how reliable the automated goldcard maker is but the guide i used for my DZ had me make the goldcard manually. I recommend hexeditor
have you done your goldcard with the hexeditor?
please help me.. ;(
Use the goldcard windows program to only patch the "image you get from the website" to SD card.
Reverse your CID yourself like this:
First learn your SDcards CID:
open an adb command line and type:
adb shell cat /sys/class/mmc_host/mmc2/mmc2:*/cid
it will give your sdcards non-reversed "cid"
than reverse that CID like this:
Original:
AB CD EF GH IJ
YOUR REVERSED CID:
IJ GH EF CD AB
and use that reversed CID you made to submit to the website to get the image file to your email.
Than patch that image file with a goldcard helper program.
I did this and it worked!
Thank me with the button below if yours worked too
Hi, I have the same problem with same Desire Z firmware. Have you been able to find a solution yet?
