Z1 - no imei, no baseband

[quickstyler]

So I got this Z1 (C6903) from ebay and tried already everything imaginable...

Problem 1: NO IMEI + NO BASEBAND
Problem 2: Due to this... no wifi and reboots (reboots can be fixed by 4.3 firmware)

Of course I've already tried to flash C6902 firmware according to http://forum.xda-developers.com/showthread.php?t=2685880, but I'm quite sure it's a C6903 - see pictures of PCB and ID-Tag

- I flashed all [NUT] firmwares I got here - still no imei, no baseband.
- I downloaded according to the SI-Number the branded firmware (via xperifirm) - no success
- I flashed every firmware I got here on top of the branded firmware - no success
- I tried about ~25 different firmwares, every version, different regions or commercial - no success
- There is no TA-Backup, but checking it via *#*#SERVICE#*#* it seems to be ok (see pictures)

Anyone got any other ideas or the same problem? I read on some topics that the imei recovery when a correct firmware is flashed...like magic...but this doesn't happen to me.... Maybe someone can share some magic to me?

Hope this trick can help.
open build.prop by text editor.

ro.build.charcteristics=deafault
# end build properties
#
#system.prop for surf
#

Add your desire IMEI Number string as follows:

ro.build.charcteristics=deafault
ro.imei=123456789012345 (replace this with 15-digits of your IMEI)
# end build properties
#
#system.prop for surf
#

Reboot, *#06# to check if IMEI exist. If yes, reflash correct firmware to your phone.
