IMEI and baseband missing - Sony Xperia ZL

My Xperia ZQ (C6503) was working until today, when I lost my baseband. I already tried flashing 4.2 and 4.3 stock, wiping data, restoring TA backup but nothing helped. Can someone help me please?

Did you try flashing it with flashtool, or just a zipped rom from recovery?
Try to find the FTF for your phone / carrier and flash it using flashtool.

[Q] Why do I always get bootloops?

Hi everyone,
I am new to flashing and rooting. I have rooted my Xperia S using bin4ry method (locked bootloader). I found CWM for locked bootloaders which use a .bat file to flash CWM.
I always get a bootloop by using that CWM. I got bootloop once, then I restored using flashtool. I gave a second try and I got bootloop again!!!! I got extremely annoyed. I was trying to install a flashable zip mod of Xperia T small apps.
I have wiped dalvik cache before every time I flashed. No luck.
Can anybody help me out?
Maybe the mod isn't for your system Version?

I m running 6.1.a.2.50. Where is it possible to get a bugless CWM?

I don't know. CWM for locked bootloader hasn't been updated for a good time.

How do other people with locked bootloader use CWM?

Don't worry, framework-res was the problem, not cwm.

You need a custom recovery. If u r rooted download freegee from the app store and install cwm recovery. You will have problems with touch with TWRP

It only does such if your bootloader is unlocked right?

I think, not sure, that it used to at Xperia X10 and Arc times. With S and beyond, I've been told it don't cause any problems anymore...

Yes.
You can easily flash stock rom with flashtool.
Is stock ROM the .ftf file?

Yes.
You may even take a backup in CWM before flashing CM 11 and then restore it so no need to flash through flash tool
Does the backup store in the SD card?

Half yes. Half no.
If you take cwm backup then you can simply restore it back to get your settings and apps back. Then if you want stock kernel flash kernel only through flash tool. So you have a stock ROM along with your saved settings.
When you want complete stock same as when You first started it then you need to Flash full stock ROM, wipe data and cache and relock bootloader.
