UPDATE 14/9/2013
I have managed to fix the problem!!!!
Found here: http://forum.xda-developers.com/showthread.php?t=2441854
What I did:
1-Flashed fresh uk generic 254 ftf. with full wipe. when done, confirm offline charging is working. WAIT FOR STARTUP CHECKPOINTS TO FINISH! and a big POWER OFF button will appear, Press it and phone will reboot. power off normally and check offline charging, if not try repair with SUS or PCC. ***VERY IMPORTANT! Confirm offline charging is functioning before going any further!***
2- Download vroot from link above, unzip it and run it, allow it to update.
3-Connect your SP to PC (maybe important? make sure PCC/SUS/flashtool are not running)
4-Click the ROOT button in VROOT - wait for confirmation - phone will reboot
5-you will now have root, but the superuser app is chinese.
6-Download Superuser by ChainsDD from playstore (superSU and cwm superuser caused rebootloop in my phone - ChainsDD did not)
7- open ChainsDD superuser app, chinese superuser will ask to grant superuser permissions - accept it
8- in ChainsDD superuser, go to info, tap to check for updates, then click update button - this updates superuser binary
9-uninstall chinese superuser app. i used titanium backup.
10- ENJOY YOUR ROOT WITH OFFLINE CHARGING WORKING!
I ACCEPT NO RESPONSIBILITY IF YOU MESS UP YOUR PHONE - THIS HAS WORKED FOR ME - IT MAY OR MAY NOT WORK FOR YOU.
Please press thanks! :good:
Ok, so some of us are unable to charge the phone while it's switched off after rooting, the phone turns itself back on.
There must be 1 common factor why this is happening. Let's try to find out what it is, and hopefully devs can help us.
Please report the following :
Is offline charging working:
Model number:
Bootloader locked/unlocked:
Bootloader unlock status (yes/no):
Simlock:
Rooting method:
Now, I don't know if any of the aforementioned are possible causes of this issue, but they could be.
Please keep the thread clean and simple, I don't want any arguments, or people saying it can't be this or that, I had enough of that when I was trying to prove that unlocking bootloader broke bravia engine in Xperia s. And it turned out I was right.
This is just a simple data gathering exercise to attempt to determine a common factor for this issue.
I have had this problem with both 245 and 254 fw.

This how make u can Offline Charging
If you already rooted on 2.254 Just try this , this is working good
Download latest firmware 12.0.A.2.245 then use flashtool for flashing your Xperia SP
Open Flashtool than do like this
Then turn on your phone
and wait for Battery Calibration , wait until finished then choose Turn off
Then try charge it, it will be offline charging
*Note : backup your data , this will be wipe all your data but not your root
I my opinion the offline charging problem can be due the face the we used the way around method for rooting.
I am also having this issue.

Well, it seems so far there isn't a common factor...
@zolaisugly, yours is working, did you start with a fresh/clean install? I.e. No user apps, nothing set up? Wonder if that's it?

Are you saying root 254 then flash 245 without kernel? so your running 245 fw with 254 kernel?? Or is that 245 a typo?

why should Battery Calibration wipe our data ? it just doesn;t make sense but i just want to confirm if it is inherent part of flashtool battery calibration.

Here's what i did when I got my Sp from 3 store UK. I was excited that there was updates available i was on .211 at first, but sad as no root or cwm available, but still updated to .257 using Russian ftf. (Then when available I updated to .245 this was after root and cwm were available) From this link http://forum.xda-developers.com/showthread.php?p=44550360
After upgrading then loaded all my apps and data etc,then came root using doomlord method,then installed cwm. I have deodexed using a deodexed ROM but still based on Russian firmware.
Maybe that is the key...use Russian ftf
I have not tried any of the mods posted here but do use the xframework and modules to get the phone how I like.
Guess I have been lucky as regards the offline charging,but not so lucky as i suffer with poor WiFi signal.
Sorry for the long ramble but just thought I would write the whole process of how and what I have done.

Battery calibration is nothing to do with flashtool and it doesn't wipe data. When you flash a new fw the phone will go through a self test process, then come up with a screen with a big button saying POWER OFF and a little one saying use phone.

ok. Thanks. my thought exactly. we could just untick and tick the boxes of items we want to keep or wipe. Hopefully, there is a way to resolve this offline charging issue soon. I had the same problem but it is much less of a problem to me as I hardly power down my phone.

Hmm, it's not worked for me...
I first rooted when 257 was latest fw, which was ok - no offline charging issue, but nfc wouldn't work.
I then flashed the Russian 245 with flashtool (with full wipe) - which caused me to lose root, this is where I first got charging issue.
Repaired with sus and all good.
so I tried again, rooted by rolling back kernel to 257, using the doomlord method then back to 245 kernel, charging issue came back, I also had issue with nfc again.
I then repaired with sus and went back to 100% stock (Russian 245) and all was working ok, but no root.
Next, I went to a generic 211, updated to 245 with pcc (this was before 254 was available) rooted again by doom method, charging bug is back. But nfc ok.
Most recently I've flashed a UK generic fw but did ota update from 211 to 245, rooted by doom method again, bug is back. I've then updated to 254 with pcc as no ota notification, so I now have no root and no offline charging! Again, nfc ok.
I'll have a bit more of a tinker this weekend. Might start from scratch with my original Orange/ee fw and see how it goes.

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:

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.

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
Regards,

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.
I've used...

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.

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

Flashing from .757 gave me a bootloop. There are no more links to .290. Hmm...
I'm on ihackers 2.1 ROM android 4.3
rooted
unlocked bootloader
I wanted to go back to stock to C6902_14.2.A.0.290
I found the method but I'm not sure if this is the right way http://lionking853.blogspot.co.uk/2013/11/how-to-go-back-to-stock-firmware-on.html
and if it is the right way, after going back to stock ROM, will my phone unroot and relock again?
Can I just go ahead and do this or must I relock bootloader first?
please help me since I never done this before, only rooted and unlock that I did.
Thank you so much folks

I downloaded stock C6902_14.2.A.0.290 which is 4.3 it's the tft file
can I just flash it using flashtool? I want to wipe everything, no need to back up, I mean I want it to feel like a brand new phone. like factory reset.u know, and It doesn't matter about root or bootloader,

if you don't want to relock your bootloader then just go back to .290 with flashtool
ok

Thank you, I'll do that
done
I'm finally back to stock ROM and it's much faster than custom ROM
I think it is much more stable too.
I'm no longer rooted anymore but bootloader is still unlocked.
I'm happy now
You can install custom kernel & have root

If you have an unlocked bootloader, you will not be able to update using PC Companion. I didnt know all this **** were involved in Sony phones.
I had unlocked my bootloader a couple of days back, didnt know I had to backup my DRM keys and ended up losing my warranty. Now I cant even update my phone using the official updating method.
BTW... the recovery is bundled with the kernel, thats why people refer to it as flashing a kernel instead of recovery. I didnt know this until 2 days back.
Thanks

Thanks anyway but I found the method and my phone now relocked bootloader
If you do have a TA backup then you don't have to do anything else then restoring it on a stock rooted firmware..If you don't then use flashtool to relock it..
Revert back for more help..
Hit Thanks if I helped you..

If I am on a Locked Bootloader and on a rooted custom ROM, will Sony PC Companion detect my phone when the next update comes??
This is stupid. If you are in 4.3 (.290) with un-locked boot loader you cant update via PC companion or SUS.
I ended up going to 534 (4.2) via flashtool. Root it, restore TA backup and then use SUS to update. And flashing the latest 4.3 via Flashtool din work.
No PC Companion or SUS won't detect your phone.. You've to manually flash a valid ftf from Flashtool.. Then you can connect & update your phone through PC Companion or SUS..

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.
