Hi guys I'm considering to purchase the Z1 beocz I lose my precious Xperia S a week ago :crying: (very very sad, really love it)
As I'm those type who will definitely root the device and probably unlock it some time later, I really care about the camera problem.
I read the the DoomLord thread which told us to backup the "TA" thing before unlocking the bootloader, so we can restore it and have the camera working again.
May I ask what the "TA" actually is?? how can I backup that thing??
So after I retore it, is the bootloader still unlocked??
If i screw up the TA thing, can I relock the bootloader and save the camera by the official repair function in Sony Update Service??
Sorry I'm noobish but plz explain these things to me thank you!!
BTW, are there something i should consider before i buy the phone?? Is it the right time to buy it??
thank you
Its a partition on the device called trim area.
There is a thread about backing it up and its very easy to do.
If you do not have a TA backup then relocking the bootloader will NOT fix the camera.
Also, do not restore someone elses TA it will hard brick your phone

How if I repair the phone with update service after relocking the BL?
And after I restore the TA, is the bootloader still unlocked??
I'm wondering if there's possible to keep both bootloader unlocked and the 20mp camera working...

Restoring TA relocks the bootloader
There is no way to have an unlocked bootloader and working stock camera
I'm getting a little confused!
After rooting + custom recovery + custom ROM, can I restore my TA to get the camera back? Obviously would like to keep root and the custom ROM.

Depends on whether the custom ROM requires an unlocked bootloader. Some custom ROMs don't need your bootloader to be unlocked. So that means you can still have root + custom recovery (which don't need unlocked bootloader) + custom ROM, and your bootloader is still unlocked and your camera is still working.
But if the custom ROM requires an unlocked bootloader, then restoring the TA will result in the bootloader being relocked, which means your ROM no longer working.
Someone correct me if I'm wrong.

Basically you can only use roms based on official firmware for now (and have a working camera) afaik. All the roms in the original development area (based on AOSP, custom kernels) required unlocked bootloader and as a result have a non-working camera.

Dear all,
I have one more noob question again.
I was use a tool name Backup-TA-9.8 to backup my Xperia Z1 DRM. If I unlock it boot loader I know that the camera will not work. But if I relock it bootloader and restore my DRM. Dose the camera will work well again?
Best regards,

But when relocking/restoring you will not be able to use those custom roms anymore (those not based on stock), just so you remember/know.

Small question, wouldn't it be possible to unlock, root (by pushing su binaries in a custom recovery and restoring stock recovery), and relock? No reason it wouldn't work imo, and I find this procedure faster than doing the downgrade, root, recovery, upgrade method

yes, but when you unlock you void your warranty, so unless you are planning on keeping an unlocked bootloader I reckon the extra minute it takes to downgrade etc... is worth it to keep your warranty
Also,
There is no such thing as a "stock recovery" on Xperia devices.
Also,
there is no need to install a recovery on the downgrade method if you do not want to.

No warranty here anyway.
I remember OTA-upgrading an Xperia Z, and that simply flashed a zip package in recovery. Why would there be no stock recovery?
And you need to install a custom recovery to do the upgrade, either that or copy files while the system is running, and I'm not sure how the latter would work without the system crashing at some point.

No.
Xperia devices have never come with a stock recovery accessible for the user.
Upgrading OTA means you do not flash it in recovery, you download the files Over The Air and then the phone upgrades itself.
No official upgrades are done in recovery, only custom kernels, custom roms or custom updates are flashed in custom recoveries

I know what OTA means, on previous devices with stock recovery, it simply drops you into recovery and does the flashing itself without the user ever having to touch anything. Same goes for wiping user data, it's done in recovery.
Whether the recovery is accessible to the user or not is another thing, and I didn't know about it, so thanks for that.

How do you do a TA backup on the Z1? When you do the TA backup before doing anything else you usually do not have root yet, so I wonder how to backup the TA......
Follow any if the several guides in the dev section on how to backup TA. I can see at least 2 guides on the first page

in which firmware u unlocked the bootloader and rooted the z1?
If you Unlocked your Bootloader when you was on JB 4.2.2 then you upgraded to KK 4.4.2 then that's the mistake...

no, i bought the phone with kitkat 4.4.2 on it
all what i wanted is to root the phone, while having the camera working at the same time
but not root and a damaged camera ..
help me out ?!
Something wrong here, i can confirm unlock bootloader on 4.4.2 can't stop camera function. (i unlocked my phone on kitkat firmware 757, all working fine)
I think you did not backup DRM keys too?

Something wrong here too, it not come out of box with Kitkat, so I presume you was thinking you have it but you don't.
If you brought it used then different story, but the story of the phone we don't know.
So I don't know how to help here as Unlock Bootloader on 4.4 do NOT Breaking the camera functionality.

I bought it new from Sony with Kitkat on it in middle east -Dubai
The issue is being sorted via PM with me.
However, this is a synopsis.
The OP unlocked the bootloader on 4.4 - Camera works.
Then, instead of just flashing a custom kernel to gain root, the OP followed a guide for a locked bootloader to gain root. Once they downgraded to 4.2 the camera broke.
In order to fix this the solution is
1) Relock the bootloader (by restoring the TA partition if a TA backup was made, in this case not, or by using flashtool)
2) Use pccompanion to upgrade to latest FW
3) Re-unlock the bootloader by the official method (Or flashtool, if it was re-locked with flashtool)
4) Flash a stock based custom kernel
5) Install SuperSU from the play store.

I don't think so if you unlocked on 4.2
If you unlocked on 4.3+ it wont break anyway
try relocking the boot with flashtool, upgrading by pccompanion then unlocking again with flashtool

So I want to unlock my phone Bootloader and install a fresh AOSP 4.4
Mine current android version is 4.3 Jellybean ( 9.2.A.1.199) and on the sony bootloader unlock site when I insert the dial number it says "Root status ...... Allowed "
I rooted it today ( havent installed recovery buy I can do it later)
My questions :
Can my phone brick while trying to unlock the bootloader?
Do I need to download the latest version or the 4.1 version of android ?
All this I'm doing 'cus my 1 year warrantly has ended today so Why not ? :good:
Don't think the bootloader unlock procedure has much risk of bricking your phone... especially if you use the official Sony Bootloader Unlock method. But you may want to read up on backing up your TA before unlocking the bootloader.

I'd also suggest backing up your TA first. It's all in here: http://forum.xda-developers.com/showthread.php?t=2292598
If you unlock your bootloader, you lose your Bravia Engine. You can get it back when you lock bootloader, but only if you restore your TA. If you don't have this backup, BE is most likely lost forever.

So Now I only need to unlock my bootloader ?
Still one question :
Can I use my current version of android 4.3
EDIT : Unlocked the bootloader , put rom , gapps , wipped WORKING AS A CHARM
Thanks for the help !
And if I would like to restore to stock do I need to relock the bootloader ?

Nice!
If you want to get your phone back to stock, just flash a stock FTF. Flashtool does not require the bootloader to be relocked for that.
Unless you mean "stock" for warranty purposes, or selling the phone... then I guess I'd say yes to relocking the bootloader, after flashing a stock FTF (and also restoring the TA, of course)
Thanks 4 The Info )))
I used to own an Xperai Sola. Before unlocking the bootloader I didn't know that I had to backup the DRM keys so that I can get back the "Bravia Engine" and "Download music Info option for Walkman" after the bootloader was unlocked. The information that we can backup our DRM keys came 6 months after I unlocked my bootloader.
These are my questions:
On Moto G 2nd gen do we need to backup something similar like the DRM keys of Xperia Sola?
What function do we lose when we unlock the bootloader other than Warranty? Does OS/Android update still work?
Does re-locking bootloader takes the phone back to its previous unlocked state?
@Falcon G
@vinaybaboo
@bhavin192
2. You can update phone after unlocking bl if you don't make changes to OS i.e. Xposed etc.
If you update even you have made changes to OS your phone will go into Bootloop
3. Yes Re locking and flashing stock firmware takes it to locked state
@NWKENT can answer this Questions more clearly
I´m also with similar doubts. I came from Samsung-way of unlocking bootloader.
Just to ensure if get it right, If I just put root on device, I still be able to update original rom from Motorola ?
It´s a pity we can change anything with xposed (in order to keep upgradable), bcos it´s small things we get used to, and we miss on stock roms...
Thanks,

I guess if you wipe data and unnistall xposed and then flash stock recovery, you will be able to flash via OTA. No need to unroot

1. No you don't need any DRM keys
2. U lose nothing rather than your warranty. Ota works if you don't install custom recovery and change the kernel
3. The new locked state is different than the OEM locked one

Falcon G, thanks a lot for replying.
If the new locked state is different than the OEM locked one, then if a user wants to unlock the phone a second time, does he follow the same method he used to unlock the first time?
So, once the phone has been unlocked it is not possible to lock the phone to back to its OEM locked state?

Yes you will be able to unlock the device.
And no you cannot get back to the original oem locked state
So I unlocked(htcdev) and rooted(twrp) and now I wounder if I should re-lock for security? I read that the boot-loader could have an authorized os list. Since both the system and recovery are os's would a re-lock put twrp out of control?
Thanks
I'd like to know this also. Fortunately relocking seems to be easy.

Never relock with custom roms or custom recovery still installed on your phone, this will result in bootloop.
Only way to stop this bootloop will be to unlock again but unlocking the bootloader require the stock recovery to be installed.
So with custom recovery installed and bootloader relocked = bootloop = can't unlock again. You'll have to reflash the whole firmware in ruu mode to get back the stock recovery over the custom one and then you'll be able to re-unlock to stop the bootloop.
So short answer, don't relock when not 100% stock
Ich, thanks! Glad I asked first instead of taking the chance..
