[Q] SIM card not working after a downgrade.

Hello, I have a problem with my phone. I bought a used Xperia Z and it was overheating, so I decided to downgrade it to 4.4. I flashed the phone with a stock 4.4 rom, but after that the SIM card stopped getting detected. I used the PC Companion to update it back to 5.1.1, but the SIM card problem persists. What do I do? Is it SEMCboot related?

،maybe you hit the bottom of simlock.ta

No basband version, OTG not working, not receiving OTA updates.
I just dont understand why am having these issues
The phone is locked on the network, but sim is working( i have to pay a fee or they will cut off my IMEI) and wifi is working

Anyone?

Did you try it to update it with Xperia Companion in a PC? Maybe you can solve your problems with that.
Mine come with Lollipop and I update it with Xperia Companion to Marshmallow.

No sim card insterted after flash firmware with simlock.ta

My Z3+ is from Japanese Au carrier (model SOV31). It has been sim unlock with code. I just download latest firmware with XperiaFirm, create FTF file with flashtool with simlock.ta and flash the firmware by flashtool 0.9.19.3 without checking exclude simlock.ta
After flashing, My phone does not recognize any simcard. I try to flash stock, factory release firmware (lollipop 5.0) but it still no result.
Any way to fix this.
Thank you for your kind attention.

how to downgrade bootloader of A320FL please help

1. Incorrect place to ask
2. WHY DO YOU GIVE US YOUR IMEI XDDD. Now you are literally in danger if a hacker want to do something illegal with your IMEI.
3. You can't downgrade from Android 8 to Android 6.

1st. flash stock firmware for a320fl DUAL SIM
2nd. boot your phone, enable oem unlock
3rd. back to odin, flash stock 7.0 firmware *Choose the correct file
4th. enjoy your dual sim

This guy is silly of something he hasn't deleted the IMEI xDDDDD

[Help] Flashed verizon firmware on my Att Z2 force

Help Guys!
I know I am a dumb f**k but I accidently flashed xt1789-01 Firmware on my 04 Model.
I have IMEI and everything showing on my phone.
But my Sim isn't working for weird reasons. (It says the sim card isn't compatible with Verizon)
I wanna revert back to Att but it isn't as easy as upgrading to Pie on my Att z2 force.
It won't letme flash Att back on my att phone. It says wrong firmware (lmfao?).
I guess it says this because of the last update on att model was Oreo 8.1.
And the last one on Verizon was 9.0.
