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] Tried to flash ROM, now stuck on Sony logo

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.

Here I am showing my ignorance. I followed the instructions here (http://forum.xda-developers.com/showthread.php?t=2478003).
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.

Relocking Bootloader Xperia V

Hi all, sorry if this has been posted somewhere else on XDA. I used Fastboot with the code that sony sent me a while back to unlock my Bootloader. What I want to do now is to lock my Bootloader again to update to the new official rom. I would however love to flash a custom rom, but can't find a detailed enough step by step guide as to how. Also flashing custom kernals sounds risky, not sure if it is though, being the reason why I have not flashed anything beyond the Botloader. Help would be greatly appreciated.

You can use official 4.3 without relocking your bootloader.

[Q] Unable to downgrade to .534 after mainboard change!

I have rooted my Z1 many times without problem, first downgraded to .534, root with Bin4ry's root tool, then flash the .zip file from recovery and flash stripped .ftf with FlashTool.
By rooting this way I can keep my bootloader locked.
A couple of weeks ago I had to send my phone for repairs when the call speaker gave up and they changed the mainboard (new IMEI).
After this I can not downgrade to .534 anymore! It will stuck at a bootloop, with only the Sony logo showing. Downgrading to .257 (the version after .534) is no problem though.
I have tried many different .534 tft-files, including NUT's.
Any ideas? Could this new mainboard be incompatible with the oldest firmwares? Sounds unlikely to me.
Thanks!

If it's incompatible with 534 then i'd be surprised, my guess is that it's a dodgy download and you should re-download the FTF file or an alternative and make sure it's the only thing that your computer is doing at the time, even check the MD5 checksum if it's available.
Are you flashing the full FTF file when downgrading and allowing for a wipe?
Only problem i've had when downgrading is losing the IMEI but after you've rooted , installed a custom recovery and installed a custom rom that'll come back anyway.

Which version of flashtool are you using currently? I've found that some firmwares just don't like the older flashtools.
What about different USB cables? Shouldn't make any difference but I thought I'd ask. I find it odd the way it'll work for newer but not older firmwares, perhaps someone else should chime in with an idea.
I'm all out, as this isn't something i've come across and everything i'd try myself i've told you.

Since I have always used Bin4ry's tool, I guess I have not noticed any thread about vroot being dangerous.

Right now I have .257 firmware flashed which is a 4.2.2.
I have tried to root with Bin4ry, vroot, Kingo, and [NUT]s recovery, but it is not possible.
Everywhere I look people say that it is a must to downgrade to .534 when rooting with a locked bootloader.
What have I missed?
Thanks,

257 was the first one that closed that exploit, you have to go back further.
I know you say 534 does not flash for you, but what error does flashtool give?

Thank you, I misunderstood an thought .257 was rootable too.
No error in Flashtool, flashes fine but is stuck on bootloop with Sony logo.
Tried .518, .526 and .534

make sure you do not exclude any part of the FTF and wipe everything,
Can you get a log from the phone?
Make sure you backup and clean your sdcard (So there is no trace of recovery files on there)

I have cleaned the internal sdcard and tried without external sdcard and simcard.
Don't think it is possible to get a log file from the phone while in bootloop?
If my new mainboard is incompatible with .534 and older, I guess other users would have the same problem?

Anyone who can HELP me because the Baseband lost!!!

I flashed the wrong firmware so that my phone can not use LTE now.
I mistakenly brushed into the ROM of the ROG phone I.
The result is WIFI works except LTE network.
I tryied flash any new ROMs.
Someone tell me that he can see the Baseband ID in 9008 mode.
So, any big boss can help me how can I find back my baseband?

Any other suggestion?
