Urgent! Sim Card not valid after flash!

I was trying to flash the new 4.3 Rom and somehow I have managed to make the sim card unfunctional. even after going back to 4.2.2 the phone always says that the sim card is invalid. I have a TA Partition backup.
I really need the phone. Thats what you get when you are playing around.
Why is the sim functionality gone? Anyone experienced the same?
Ok its because I lost the IMEI number. Nice one some people on the board had the trouble too after upgrading.

Had the same problem rerolling to older versions.. but i think its the regional code from the file.
Flash a version near/from your region and the sim card will work properly again.

It also happened to mine while I'm trying to root on 4.3. I downgraded to 534 after unsuccessful of rooting on 4.3. Then I lost IMEI and showed sim card is invalid. Fortunately I made my original 270 ftf for back up. I flashed 270 again and I got back IMEI and working sim card. I also found in other thread that if you want to downgrade 4.2.2 from 4.3 you need to flash exclude baseband. If not you will get that IMEI and sim card error. Try to update 4.3 and downgrade 4.2.2 exclude baseband if you don't have original back up like me. Good luck !!! :good:

You a need a functional TA backup to do it.
Downgrade to the version where you did the TA backup through FTF then you can see your IMEI again.

Ok I'm running 4.2.2 I want to know is there a way to back up my phone my bootloader is locked.
I have root but I didn't install custom recovery. I want to try 4.3 but I want to make sure I can come back to 4.2.2 without loosing imei.thanks

Thank you for your advice but in my case I didn't need to backup and restore TA to get back IMEI and working sim card. I'm just flash my stock 4.2.2 ftf that I backup before and everything is working fine now (both IMEI and sim).

As per reply from 4.3 rooting thread, you can downgrad 4.2.2 from 4.3 without losing imei but you need to exclude baseband when you flash 4.2.2. :highfive:

It should be ok with just exclude baseband. If not wipe all data on phone.

I tried to downgrade to 257 I used flashtool it flashed but remained on 4.3.now I can't use flashtool everytime I select a ftf it says can't open. Is it because it's a custom rom.please help.I tried different ftf even a 4.3 stock ftf.

Try to restart your computer. If not OK, uninstall and reinstall flashtool. Try to redownload ftf as well. Good luck buddy.

I've also encountered the same problem after having downgraded from 4.3 to 4.22 with the intention of installing a custom rom.
I got so far as flashing a generic uk 4.22 ftf, rooting, backing up ta partition and trying to install dual recovery for LB but after a few attempts only TWRP would install and not CWM which is what I needed to install the rom and so decided to go back to stock and try again some other time.
Only now I have this Invalid Sim message and can't find a way to get my phone working as a phone again, this thread has mentioned a number of fixes but as I had to flash an old ftf first in order to root and continue, my backup ta was done after this problem surfaced and I do not have a copy of my original ftf so it would seem that what you guys tried won't work for me, anybody have any ideas?
Any help would be greatly appreciated...

If you don't have your original FTF doesn't matter, download from here http://forum.xda-developers.com/showthread.php?t=2469191 the unbranded generic FTF and flash it to stock. Your phone will working back fine.

That did the trick, ta very much. Still having the same problem when I try to downgrade again though, I am going from .290 to .257 (I read somewhere that you have to go via .257 to reach the rooting promised land of .534) but still get the Invalid Card notice. I have done full factory resets, enabled USB Debug, ticked unkown sources, excluded baseband and not but no joy.
Seems a bit odd to me but there must be something I am missing... any ideas? All my firmware is generic UK btw.

If you are doing this to reach the .290 rooted like here http://forum.xda-developers.com/showthread.php?t=2572988 doesn't matter too, because you will update anyway so if you get some issues in downgrade state forget about that and complete the process. The update to .290 should fix them. Are you getting this problem on rooted .290?

I am trying to install the Criskelo rom ( http://forum.xda-developers.com/showthread.php?t=2560068 ) I got as far as installing dual recovery but I could only get TWRP working not CWM so stopped there and back tracked thinking I was doing something wrong. Not sure if the issue I have now would be fixed upon installing the rom, couldn't figure out why CWM wouldn't install and as the Invalid Card was the only other known issue I figured something went wrong in the downgrade process and have been working at that since...

The update kernel of the Criskelo it's a .290 so probably it will fix this issue but if you flashed the recovery and you get only TWRP working and not CWM i don't know how this happen. There is 1 way to boot in TWRP and another one to boot in CWM.

[Q] SIMLOCK - Xperia Z1 C6903

Hi,
I was trying to install the deodexed version of 4.4.2 Stock rom for my C6903
But it stuck at SONY logo,
so i flashed the older 4.2.2 FTF (C6903_14.1.G.1.534_1276-4314_R2A.ftf)
And now my phone is SIMLOCKED what the hell.
It did not have a simlock before, because in Belgium they don't do that.
Is there a way to get rid of it without unlocking bootloader to get full control of device kernel and ****...
FYI - I have a TA Backup of a working 4.2.2 and also of a working 4.4.2, might that help me getting rid of the simlock?
Thanks in advice

So now i did restore the TA Backup i had for 4.2.2
And guess what my imei number is gone,
and still no network ...

IMEI will come back if you flash a 4.3 or 4.4 FTF
SIMLOCK should have nothing to do with flashing FTFs
Try and flash a FTF from your original phone and try again

I had the same problem, it happen when you flash a different FTF for your region, I updated to 4.3 and it disappear.
...btw if you execute a Factory Reset maybe it will fix the problem.

Dude, this is exactly what happened to my z. I think it's an inherent flaw in the Z's hardware!
That baseband is dead, it can't be fixed!!! Srry bro

so if you are in kk 4.4.4 baseband cant be fixed just by flashing only Baseband from a previous rom like JB in flashtool? so is now a dead phone? cant baseband file be moded to avoid restart or disable using the damaged hardware?

[q] XPERIA ZR unknown baseband and blank imei help!!

Hi! I need some help my Xperia ZR c5502 4.1.2 got Unknown IMEI and baseband after flashing …
With no backup
ONLY ftf build 10.1.1.A.1.310 is working but always no Wifi and Signal I read some threads that it's because of the unknown baseband and IMEI
This is some things I tried
Unlock/relock bootloader root and install cwm recovery
tried Flashing Different Xperia ZR FTF with even Different Country using flashtool still no luck always got stuck in Bootloop
Wipe date/cache/partition No luck
Repair with PC Companion still no luck stuck in bootloop
Is there any other possible way to fix IMEI and baseband without bringing it to the repair center?
Any more suggestion?

Did u unlock bootloader? and while relocking, did u do it properly? DRM keys and TA partition restore?
And why are you still on 4.1.2? did you try 4.2.2 or 4.3 or 4.4.2 roms for your specific region?
I think you might have lost DRM keys or TA

I'm stuck @ 4.1.2 tried other 4.1.2 but only 10.1.1.A.1.310 build is working on my phone other build always ends up in bootloop
tried 4.2.2 or 4.3 or 4.4.2 all stuck in bootloop.
Yes I lost my lost DRM keys and TA because of flashing without backup
Is there a possible way to restore it without backup?

Sorry mate. you cant get back DRM and TA once u lost it. its different for every phone.
Check the service menu: dial *#*#7378423#*#* (i.e. *#*#SERVICE#*#*) and choose 'Service tests' > 'Security'. If your DRM keys are okay, both MARLIN and WMLA will show up as [Key OK]. If they are erased, they would show up as [Unknown Error].
DRM keys are unique for each device, so they are not contained in any firmware download. Once they are erased, there is no way to get them back, unless you made a backup of the Trim Area (TA) before unlocking your bootloader.
---------- Post added at 10:34 AM ---------- Previous post was at 10:27 AM ----------
You should have researched before unlocking the bootloader. But thats history.
What you can do now is flash any custom roms. Check ZR android dev section. there you will find some custom roms based on 4.4.4 which needs to be flashed on unlocked bootloader :good:
sorry for your loss

Now I learned my lesson always backup >.<
Thanks! I tried intalling some custom 4.4.4 ROMS and it worked my WIFI is now working even with still UNKNOWN IMEI and Baseband much better than before with no WIFI now my only problem is the NO Service ON Simcard >.<

My guess is that as you have lost DRM and TA, IMEI is showing unknown. Thats why your operator is rejecting the service even though you have inserted sim card. try some other custom roms n kernels. :good:
