Dear all,
I really should not post this, but i will do so.
I have unlocked bootloader to install CM 10.2 NIGHTlY. Despite of the so much warnings to backup your TA partition i did NOT backup it, because i thought "I never bought music so i have no DRM keys". Oh boy, was i so wrong to think that DRM keys are not only music related.
However: i was not happy with CM 10.2 and relocked bootloader with flashtool and reverted back to stock wit a FTF file.
For now: everything works fine.
Now my question, i see that my trackid is working fine, it recognizes music, so it works, also i still have the bravia engine option in the menu. So i am missing something here? I'm a lucky bastard who did not lose the DRM keys with unlocking the bootloader? How can i check if my TA partition is intact with all DRM keys?? Also OTA updates are working fine (yeah, of course its saying no update available, only there was 1 walkan app update available and i installed it success)

Drm keys have gone for good then, BE2 won't work on pictures. Track ID works on unlocked bootloader anyway
Edit: of you go into service menu and click on service tests then security down at the bottom you will see the top two are unknown error that is your missing Drm keys

You are correct, i see unknown error 2 times. So that means i will never get the functionality back then?

Nope they are gone your Drm keys are generated via your imei number at the time your phone is made, the only way is if you work on the production line of the Xperia Z and specialise in that with the software which is very slim and the imei number would most probably change which is illegal

I just want to ask that if I create a backup using TWRP or CWM before unlocking my bootloader. And after that if I want to relock it, will I get my DRM keys back if restore the backup which I created using TWRP or CWM?

After installing CM 10.2. Milestone1 I lost my IMEI on my Sony Xperia Z.
I backed up my user data, but not the system itself...
I read in another thread you have to restore the TA partition to restore the IMEI.
Now, without having a backup, is it possible to restore the TA partition?
And where in the file system is this partition located?
Thanks in advance
I'll keep it simple:
No back up = No restore (NO WAY AROUND IT!)

Your TA is gone for good, matey! I'm truly sorry for you, but there's nothing anyone can do about it.
A word of caution: if you tamper with your TA, you *will* irreversible transform your XZ into a (very stylish) paperwieght.
PS: TA has nothing to do with your IMEI
thats why forums like this exist so you can read everything you need to know before u start playing around.
before i rooted my 1st android i spent more than a week just reading and browsing bout it. now i know what i can do without makin paperweights
cheers
ps if u somehow manage to fry ur phone you might get new one (if unrepairable) but i wouldnt try it

You know, long time ago I used CM on a different phone and all went fine and smooth. Thus I did not expect any problems. Maybe using a CM nightly or Milestone may cause some higher risk... But, I was able to install CM from scratch and get my IMEI back. Sometimes I learn by the hard way, no pain, no gain Oh, I purchased Titanium backup yesterday, lots of people talk about this tool, they say it´s useful :laugh:

Incorrect. IMEI is stored inside TA partition. Flashing some ROM's may make it seem that it has disappeared, but it is still there. Just flash a stock FTF with Flashtool and it should come back. If not, TA partition may be corrupted, and unless a restore of an unccorrupted one can be achieved, then there is no hope

yay i got this file !
im using z3c on newest cm12.1 nightly.

i got my TA backed up when i got my fresh phone.
there MUST be a way to inject this.....
can anyone help?
NOTE: MODS, i know i could have used an existing thread for this, but i need the information in a proper way and maybe ask some repeated questions.
Hi guys,
I recently bought my first sony phone. Mighty impressed, i must say. Being an old HTC fan, i didnt expect i will ever make a jump, but this phone hooked me.
I have worked a bit for the development of HTC and some other phones, so i know what to look for and where to. Reading all the guides here, this is what i concluded if i want to safely unlock bootloader and flash some CM goodness. Please read my steps and let me know i am doing the right thing:
1. Root (via Doomlord thread guide. Flash old kernel, use exploit, then flash new kernel back)
2. Backup TA partition (for the precious BE2 and other magical SONY stuff)
3. Unlock BL the official or unofficial way, (as it doesnt matter because i can always relock it using TA backup , am i right???)
4. Flash CWM/TWRP etc and enjoy all the custom roms. (never look back)
Much appreciated guys. I will surely contribute with my own flavor of aokp once i get the basics correct. Not so soon.
Regards

The steps you described are the proper ones

One last question before taking the plunge.
What if i flash a generic stock FTF (for my c5303 ofcourse), but not caring about the branding, will that also be okay for OTAs or will i have to repair/update via PCC SEUS?
In other words, how do i know which branding stock ftf do i need? About Phone page doesnt have that info i think.
I am not worried about system partition or anything, but i want to make sure i have stock recovery of my phone which will guaranteed work when i get the 4.3 OTA.
for rest, ill root, flash CWM and nand backup all things.
btw, it was so so easier on HTC

You can restore you phone with SEUS also with Flashtool ofcourse.
It does not matter what kind of firmware you flash as long as it is an C5303 one. I had dutch Vodafone Branded and I flashed a Generic EU one without issue the updates will be provide by Sony and not vodafone (my case).

Used sony update service to repair my phone,
Its back to unrooted stock 254
i think twrp messed something up.
Is it recommended or CWM only works?
on my old phone, twrp was more reliable.
There is something fishy with sony mobiles.
I know the modding stuff is more safe due to flashtool being always available for the rescue, however common stuff such as unlock, TA, recovery and etc are much too complicated for the newcomers.
even being n RC for porting TWRP to two htc phones didnt help me there.
Stuff dont work the first time.
In my case, the problem was,
flashtool worked the second time for flashing 254 kernel
doomlord kit worked the second time for rooting (i really dont know why, but it wasnt related to kit, something up with usb debug n permissions)
installing CWM didnt work the first time as well, (not the fault of installer, rather first time fails coz u give SU permissions just then, so something is missed, 2nd time, the SU permission is already there, so it works)
and ROM flashing almost always needs wipe dalvik/data/cache etc otherwise you might mess something up...
Its a lot safer if i see it one way, because these steps are more foolproof, but on the other hand, a lot more complicated, then say HTC or samsung phones. especially as i havent unlocked my BL so being cautious at every step.
Anyways, all things are fine now, using existenze ultra and enjoying it every bit.
Will step more carefully now on, using above as experience. Thanks all. This thread is closed until i have another problem

Official or Unofficial, you lose the DRM keys + BE2 on unlocking BL.
Only method is backing up a TA partition BEFORE unlocking... then when you have unlocked and restore the TA partition, the BL gets LOCKED and all DRM+BE2 are back working.
OK I understand but I didn't take backup before unlocking bootloader so I have even lost drm keys forever
but what if I installed custom rom will I get back BE2?

Nope. It will just be a placeholder. You need those drm keys for BE2

Frankly, you dont need to backup your stock rom... just use the backup n restore app to make backup of all important stuff. it will be stored on SD card...
Then do whatever you want... when you want to return, just lock the bootloader, run sony update service and you will be back to stock...
Someone confirm what i wrote above...

I am sorry I forget to thank you, I have already hit thanks button but I have to mention it here @NexusPrime
Hi peeps.
I was rooted a while back. Had problems with phone freezing mostly when using camera.
Sooo i unrooted, relocked bootloader and then used the Sony update to repair. So ive been on .757 pure stock and i got more problems with that, touchscreen was weird from time to time. It rebooted once a day and it didnt matter wich task i was doing it seems (when rooted it only happened during use of camera and mostly AR effects). So now i became random reboots.
Well i rerooted now and now i can use the AOSP brower again(thank god for that) and most things i wanna have working are working. Havent tested it for that long yet when rerooted but keeping fingers crossed that it will work like it should. Possibly some random reboots wich i dunno whats causing them.
But isnt it strange.
I was wondering about something though. Scrolling seems not so smooth when rooted, but that might be placebo kicking in.

I was wrong It worked just as bad with rootaccess now. So I repaired the phone again with Sony update.
I just wanna get rid if this phone now, it gives me me a headache!!!

if you get reboots on Custom Roms with Custom Kernels, well, it's not strange to me, it happen many time, BUT if you get random reboots on Stock, then I will should be worry about it. For all the other reasons you have to have them less on stock, if you really still have all this issues then I will replace it via warranty. I heard some Xperias was not fixed with any Firmware.
Well that's just it. I have reboots on stock rom with stock kernel. Usually once every day. I can't get rid of it. I've repaired and repaired and it is still the same.
Here is the funny part, the warranty of the phone expired one month before I even bought it when I was in touch with Sony. I have abit of an argue with my retailer atm since he says it's software related. And im saying I wanna return it. And get either money back or a new working phone.

Reflash stock rom via flashtool. It sounds like your just repairing the device. Do factory reset and flash stock rom.do a back up first.

That isn't anything to do with rooting m8, how you flash your phone and what you flash onto your phone, the apps you use or don't use and your actual habits you have, these are some of the things which cause random reboots and problems for the most part, the other is bad luck and hardware issues.
Particular devices did have some rebooting issues, I myself haven't had one in a long time so i don't get them at all, whether i'm on a custom rom or an AOSP rom, I do get the occasional slow down but there isn't a phone out there or PC for that matter that never slows down at any time.
What I would say to do is to clean up your internal and external memory and download a tried and tested rom, lets say monxified 6.0.3
Go back to 534 and re-root, install a custom recovery and flash that bad boy (don't forget to perform a full wipe, factory, cache and dalvic) use a full FTF to fill in the blanks using flashtool (avoid flashing system and TA , exlude wiping with flashtool) Do not restore using recovery either.
Don't flash a custom kernel either, just let the system boot and see how it runs, install one or two apps (not a massive restoration using titanium) Avoid xposed for now and reboot the phone.
See if you can leave it like that for a while and see if you get any random reboots.
Do it by the numbers methodically and you should be fine
Good luck
How do I wipe everything with flashtool.
Last time I rooted I flashed 681 with flashtool. Had strange reboots then aswell.
Let me say this, I have unlocked the bootloader and I do not have backup on my TA. Wouldn't older roms then 681 mess up my phone? Bootloader is relocked with flashtool and I ain't rooted and I don't have CWM installed anymore.
So easiest way to clear the phone would then be? And I want to use Stable Sony rom.

Yes, this is what I meant, just click on Wipe Data, Appslog and Cache. Still not a full format of your system partition but this is what it do to make a clean installation.
Well I did that a few days after I received my phone. I had the same problems back then. I actually did just that one hour before making this post aswell. Hoping it would work good, which it didn't.
If the phone would have been in my possession a little longer I would run it over with my car. Now it's quite new so I won't do that but I'm really tired of it and it's so boring have to send it to my retailer for repairs and w8 forever. Then when I get it back. I BET that they only will flash new software and test it for five min and ship it back and it will still have the same problem.

I was thinking rolling back to 4.3 though to see if that would be more stable. Noticed that, if the phone don't reboot in a day wich it normally does then the touch is acting weird instead.
And last night I stopped it from rebooting, I pressed the power button to turn of screen when it frooze and that cancelled the reboot. But after that I noticed some apps with camera didn't work.

I do miss the emoji keyboard, but that's about it. Know if it's possible to get that on 4.3?
Phone feels alot faster on 4.3, the camera reacts faster and tbh the pictures look better. No problems so far, hoping it will work. Battery time is also ALOT better!
