Need a solution from experts..

i have Z3 compact (D5803).

i have used it for a long time.

After installing "D5803_2157_Concept_6.ftf" via flashtool, my z3c lost network.
i have tried tons of methods:

1. i have flashed "D5803_4.4.4_23.0.A.2.93_TR.ftf", and rooted.
2. i have flashed "D5803_23.4.A.1.264_1289-4791_R2C.ftf" and rooted.
3. i have repaired the firmware via Sony PC Companion 2.1
4. i have repaired the firmware via Xperia Companion
5. i have tried installing twrp, when i try to install any custom rom, i get an error like this: "this rom is for d5803, d5833 etc etc... but you phone is differen"
6. i have tried this: http://firmwaremobiletools.blogspot.com.tr/2015/11/how-to-remove-pattern-lock-from-all.html
7. i have tried this: http://forum.xda-developers.com/z3-compact/general/guide-unlock-z3c-international-bands-t3091344

• So i can flash any ftf without any problem.
• But i can not install anything via twrp. (although i can install twrp)
• i can root roms without any problem.
• But phone can not connect to network..
• it always says "invalid card. emergeny calls only"
• - there is no IMEI problem..

Anyne have any solution for my problem?
Thanks...

- i have attached screenshots of *#*#service#*#* and *#*#info#*#*

Any help?

Have you tried cleaning the sim card?
Do you have a different sim card from another phone you can try?
There is also a hardware reset button next to the sim, have you tried that?
I looks like there is some sort of corruption in a system volume, looking at the error states listed.
What was the results from using PC companion to fix? any error messages?
Did you restore your TA partition? That would have been damaged in the flash to 6 concept.

Have you tried finding the right firmware for your country/provider via Xperiafirm, download it, make a tft from the file, then you know you have the correct baseband flashed.
Don't know what else to try, sorry.

Hello, thanks for the answer..
My z3c lost network, after installing "D5803_2157_Concept_6.ftf" via flashtool
I have tried cleaning the sim card.
I have tried different sim cards.
I have tried hardware reset button next to the sim.
After PC Companion, there was no error message.
I have tried all different ftf files for my country. (4.4 - 5.1 - 6.0 etc..)

No solution

Put a stock rom back on and send it back to Sony for repair
