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:

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.

If you use flashtool to flash 4.3 ftf you will get problems like not having signal after flashing previous version (4.2) and the solution that worked for me is to reinstall software using SUS. After that I was able to get signal when flashing 4.2

Hi all,
Same problem here : upgrade to .290 and install the PAC ROM, the install is ok but no IMEI (so no connectivity). Is anyone know how to solve without losing the rom.
If I flash the original/stock ftf, it works again, but it's not the PAC ROM, so 1 win for 1 loss.
Thanks
Android 4.3 obviously changes something in the phone so that if you jump to another version it won't get signal or IMEI.
Anyway, the solution is simple.
Flash 290 and then 257. You'll get the signal and IMEI. If you want, you can go to 534 from 257 and then flash any ROM you want.
P.S: you don't have to flash 534, but you can do it if you want.
@Just2Cause
I unlock my BL so if I downgrade to 257, the camera will work or it will have the same "bug" as the 4.2 FW. after flashing to 257, do I need to stay on a 4.2 FW to keep the IMEI or can I flash the PAC ROM (which use a 4.3 FW) ?
Also, when I did the upgrade to .290 I use the sony companion app and it gave me no probleme (IMEI, call, sms was ok) it's specifically the PAC ROM that reset the IMEI. So I wonder what differs at low-level between the stock .290 and the PAC ROM, that can affect the IMEI
Tks
Download any .ftf (GENERIC is recommended) flash it using flashtool, and download the .ftf kernel for that specific ROM that you have flashed and flash it also using flashtool. i had the same problem downgrading from .290 to .534 i forgot to flash the kernel for .534 so i was stuck with IMEI 000000000.
Cheers

It's not the PAC ROM that resets your IMEI, I also got same problem when I downgraded from 290 to 534.
I'm afraid that you will lose camera (not sure, just maybe) after downgrading you will be able to install PAC ROM without any problem.
There must be something in Sony 4.3 firmware that needs to be ported to other ROMS so the camera gets fixed.
I got it working!
IDK if you guys have figured it out yourselves but here is what I did...
After unlocking my bootloader on .290 I flashed the latest nightly build of PAC-man. Same as you guys My IMEI number was 000000000.
So what I did was flash [NUT]'s .534 ftf for downgrading to 4.2.2 (found here: http://nut.xperia-files.com/files/C6903_14.1.G.1.534_[NUT].ftf.torrent) which brought back my IMEI number!
From there I rooted my phone again, flashed the boot.img for recovery, flashed the latest build of PAC-man and tada! Everything is working.
Flash the latest firmware(.757), flash doomlord's advanced stock kernel(not the main one), flash the rom of your choice from there that includes kernel (like PAC) and now it REALLY is working.

On nut.xperia-files.com there is no 534 rom for c6902 its only have c6903
Is it fine if i flash C6903_14.1.G.1.534_nut to my c6902...
I also have the problem with network. Not with this particular build, but with all AOSP roms. "Formatting boot, system, cache, data, and everything you see" will help my phone not recognizing (or invalid) sim? Are there network drivers I can flash from zip? Sorry for asking this, but I don't want to flash again and spend 3+hours figuring stuff out and then finding out later I can't call.. I need network to work as calling is what makes my device a phone, not a tablet. Help would really be appreciated.

My current rom in use: 14.3.A.0.757 (NUT). I start the process by flashing 14.1.G.1.534 (NUT) then adding root (Bin4ry) and dual recovery (NUT) before going to AOSP roms.
Model number - C6903
Sim card - Tmobile pre-pay.
Quote from a Thread in XDA:
01. if u are coming from stock to AOSP then Downgrade to 4.2 .534 FW having Root and a Recovery ( but i think if u downgraded to 4.3 .290 FW then also it will do the trick )
02. Follow the instruction in OP with the recommended instructions - "After 5th point in Recovery go to mounts and storage and then Format boot, format system, format catche, format data, format everything u see.. Except SDcard1 (ofc).. And then move to 6th point."
If u flash .757 before coming to PA or any other AOSP ROM's then u might have trouble
As u have already done Step 01 then do a Clean reflash again with step 02.. hopefully it will solve ur problems

Hi all.
Have run into a bit of trouble.
Tried to flash PAC Man rom (Unlocked bootloader, running rooted stock 4.4.2).
I did as instructions stated, went to flash ZIPS (including pac_honami-nightly-20140330.zip) from external SD card using TWRP, after wiping everything (except my external SD card).
Received an Error message stating 'Failed', in red. Something about system.
I did a reboot, now stuck on Sony logo and cannot access CWM or TWRP.
Would really appreciate any help. Arrrgh!
Thanks kindly.

I assume the nightly .Zip I (tried) to flash was the kernel...(pac_honami-nightly-20140330.zip)?
The kernel should already be in the .zip so i don't think its a problem with the kernel. Just to make sure, check if there's a boot.img in the .zip file and are you on a c6902?

Hi guys. Sorry for the likely inane questions.
Is there anyway to get my IMEI back without reverting to .534 root, then getting to .290 root? I cannot download the .534 NUT firmware in time (it says it will be 3 weeks to download the torrent and I really can't wait that long...)
Can I just install a pre-rooted .290 firmware, given that my bootloader is unlocked?

If I remember correctly, I think you have to downgrade to .534 to get IMEI back or to the previous version before you flashed the pac rom. Download the stocks ftf from here instead of nuts

I did flash (after PAC's went awry) to .534, stock. That was when the IMEI was lost.
I did read somewhere that a locally branded firmware might get back IMEI.. Giving a .237 Netherlands firmware a try....
I hope I haven't bricked this phone...
EDIT: worked. IMEI back after flashing local firmware.
Man that was stressful!
Thank you for help guys. Really appreciated.
I have just purchased xperia z1 and has updated it to latest .757 and wants to root my mobile. May be this type of questions are already posted but i find some questions in my mind before rooting so I want too clear it out so that i may not be left with a bricked device
1. can the c6903 firmware be flashed on my c6902 without any problem ( such flash was not applicable on my galaxy ace and there was no any correct way, you are left with a bricked device, but I see only c6903 threads)
2. if so , can i flash the link of ftf on NUT thread (it is c6903 ftf----- else i have to go to ftf mega collection and flash c6902 IN ftf?
3. can the flash tool unlock and lock bootloader so that i get my warranty again ( will i loose root after locking bootloader ?)
4. does unlocking bootloader crashes camera? ( i think i read months before that 20,7 mp stop working)
5. if unlocking bootloader crashes camera shall i install Z1-lockeddualrecovery2.7.123-BETA.flashable.zip (8.47MB) from this site http://nut.xperia-files.com/ from flashtool ... if so plz tell how ..
6. how can i relock bootloader, if i unlock it?
7. what flashiing ftf withou ta means?
8. does flashing kernel, recovery and ftf are same ways i.e just put them in flashtool/firmware path and use "flash" button and follow flashing..(please do elaborate here, if u can add pics thanks). I read the noobs guide but it was for xperia x10.
9. After rooting-- flashing recovery-- all i have to do is wipe data, dalvik cache and install rom
10. i also got my back glass cracked due to my phone getting placed under my bed table while studying... i read many T&C of accidental warranty policy,, so is this reason a valid reason to get warranty,, how much will be the cost of changing back glass as accidental warranty is only 1 time useable..

Hello,
Recently I have started flashing custom roms on my UB C6903. Every time I flash a custom rom, I end up having no IMEI on phone, and thus cant connect to cellular network. I follow the following procedure:
Flash to stock .1.534.
Root
Fastboot flash boot.img
Flash custom rom from recovery
Tried with Dirty Unicorns and CyanHackers 5.0.2, and Pac-Man 4.4.4. All three end up having 0 as IMEI, or no IMEI at all. WiFi works fine. Rom appears to work fine aswell. My stock roms are T-Mobile branded, but my phone is unbranded and sim-unlocked.
Any help would be greatly appreciated.
Maybe you have the same problem i had !
take a look here :
http://forum.xda-developers.com/xperia-z1/help/losing-imei-lolipop-t3034831
hope that will help you
To follow up on this, it was a problem with my flashing routine. I ended up flashing 757, then Doomkernel for official roms, and then the 5.0.x rom of my choice. Full cellular capabilities are functional now.
To reply on your fix, Im using the C6903 model so the C6902 modem would not have done anything. It was the only result I got when I tried solving my issue. Either way, problem solved! Thread can be closed.
Wp ! for me i used the method indicated above and that worked for me
