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

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

please teach me the easiest way to relock bootloader
Thanks
done relock bootloader
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..

I'm guessing not as the only ta backup I have is from 4.3 and I've relocked my bootloader on both 4.2 and 4.4 using the only one backup without any problems
Your backup should work fine, I was on CM11 but decided to go back to stock yesterday. I restored my TA backup from 4.2.2. Effectively soft bricking the phone while relocking the phone and restoring my DRM keys, then immediately used flashtool to flash the global 4.4 update. All worked fine. On first boot it updated my NFC firmware which I believe is TA linked but its running perfectly now.
hi,
my camera stopped working after flashing a 4.4.2 stock based rom.
i am on ub but without Ta backup. The camera doesnt take pictures and cant focus. it was allright before udpate.
i even downgraded to stock 4.2.2 to see if its working but no, it is not
Any help? Or as i understand i lost my cam forever?
-EDIT-!! After playing around a long time at night, it started to work again on .290 ftf
idk what it was and what it was caused by.
But it seems that sony has problems with the 4.4 update in general.
thanks anyway
Edit2 - actually it is only working on 290. O.0 strange! as i upgrade to lower or newer firmware it stopps working.
Has anybody got an idea?
Good for you, I hear someone saying that there still a possibility, without TA, to lose the cam forever.
..and yes, KK have been reported with many bugs but not with the cam actually.
Good luck.

Well i think i will relock my BL and stay for stock. I hope i will be able to upgrade to 4.4 with camera feature. Because now it is only working on 290. ftf.
What the hell is that. Never happened before to me so strange
Thankx

Relock BL without TA do not have sense. It will not work anyway so try to keep .290 for now and soon a fix will come, or try the new KK when it will roll out, with new fixes.

So tell me exactly what did you do to repair camera issue? I'm now on RomAur v6.3 with unlocked bootloader and camera doesn't focus or take pictures... If I understood you correctly I'll have to flash C6903_14.2.A.0.290_Stripped.ftf and than C6903_14.3.A.0.681_Stripped.ftf all without TA(only TA? maybe I'll have to check something else?) using flashtool to made it work again? or do I have to flash original firmware or what?

Well, you missunderstood the Ta thing Did you make a TA-Partition Backup BEFORE unlocking the bootloader? If yes- Just restore it & you are fine.
If not, thats what you have to do/what i did to make it work.
First of all NOT STRIPPED ftf`s becasue it is only the kernel as far as i know. You have to download the whole original rom which is about 1gb.
+Edit. Do not exclude any options in Flashtool like Ta, kernel or anything else !!!! Just choose your ftf and flash!
First flash original 290. FTF with your branding (for me it was vodafone)
The camera should work there. If yes continue.
Flash original 681. ftf with your branding if possible.
The cam should work there too. If yes continue.
Now you are good to go, put your custom rom on SD Card-
Flash custom kit kat kernel/or stock with recovery
Boot into CWM and flash your Rom. Your Cam should work.

that's odd.... but I've flashed Xperia Z1 C6903 14.3.A.0.681 Commercial&Journalist w/o TA (before you told me that I should't exclude anthing) than I find out that the camera works and than I decided to flash DooMKernl v11 and RomAur 6.3 without any other steps and everything is working ok so far...

I think that I have the exact same problem (no autofocus, no picture/video, no TA backup and unlocked bootloader).
I know that there was camera issues with unlocked bootloader that was fixed by Sony at some point (maybe the .290 ?), it can be an explanation...
If I understand correctly I need to flash .290 ftf with flashtool, then kit kat still with flashtool ?
Will I still have a rooted phone after that ?
I'm glad I finally found someone with the same problem, and someone that managed to solve it !

Skip .290 and upgrade to KK directly. To keep Root you have to follow [NUT] instructions on his thread.

Ho but I am already on Kit Kat, and like LLars_PL I have camera issues. So I was wondering if I need to downgrade to .290 then reupgrade to KK, and if I'll still have a rooted handset, with working camera (JB or KK, as long as it's rooted with the camera working...)
Thanks anyway !
Edit : just saw that in [NUT] thread :
Camera problems?
You have 3 things to try to fix it, try them one at a time:
Clear dalvik-cache only;
Clear the camera app settings;
Do a factory reset in TWRP or PhilZ (this should keep your internal storage safe);
flash the ROM package again;
boot until you can test the camera;
If it works go back to recovery to restore a backup of data.

In this case I think is better to start from scratch as the downgrade is recommended with Full Wipe. Then you should downgrade to .534, Root it and Upgrade with another Full Wipe to KK. Clean installation should fix the problem.

I'll wait because the solution posted by LLars_PL seems a little less brutal, but if that or [NUT]'s solution doesn't work, I'll certainlly do that.

Downgrade to 534. Did not work for me
You dont need to root, just do it with 290.flash a original Kit kat ftf over 290.and then just Flash a Kit kat Kernel with cwm - Flash your custom Rom with root already

My wife has a completely stock (with original Sony ROM), installed the OTA to 4.4.2 and now the camera doesn't work.
Her phone is completely unmodified as it came of the box, sounds like I might have unlock it and install a custom ROM to fix what I can only assume is a bug with Sony's firmware update.
I suppose I should try contacting Sony support first, but phone/online support is usally mostly useless.
I've flashed the original 14.3.A.0.757 and now my camera is working again
Of course I lost the root (and the recovery ?!) so I need to sort this out now.
I've found that i have a weird problem with my Camera, the sound look like in mono when i listen to the sound, i've tried another app that just record sound and it's perfect, that make this only with the camera, any idea?

You can lock your bootloader by restoring the TA partition (assuming you made a backup) but you must go back to stock first, otherwise you'll get problems.
To get back to stock, download the correct ftf from here and flash it using flashtool.

when i'll get back to kitkat stock , what are the steps to follow to restore the TA partition that i have already saved????

Long story short, sent my phone away for warranty repair and it came back with 4.2.2 flashed on it. Never rooted it or modded it in any way. I wanted to update it back to 4.3 and from there eventually back to 5.1, however, the phone says that it's up to date - same thing with PC Companion. Tried to repair it via PCC and I also did a factory reset on it, both to no avail.
Is there any way to force the OTA update(unless I have to wait for X days) or is rooting and flashing the only way out of this? C6093, build 14.1.G.1.534, cust. no. 1276-1193.
Thanks in advance.

I am on mobile at the moment and hope
my search went correct. then you are on a branded swedish firmware from tele2.
Where are you from and what firmware was on your phone before you gave it to repair?
You can flash any firmware you want with the help of flash tool app.

You didn't have to unlock your bootloader to flash a firmware to your phone!
Did you backup your ta partition because unlocking your bootloader means you will loose your DRM keys?
