Hello,
I was wondering, is that a good idea to unlock my bootloader? I like to try new things with my phone and such
All opinions are welcome.

i am also in a similar situation like you. backup your TA partition first before you unlock, to re-enable the DRM features if u wish to relock the phone. now i dunno if the sync with my gmail account alone would restore all my app data,contacts etc. so for that i also make their backup using android backup utility or pc companion from time to time.(u must know once u unlock the BL u will have the internal memory wiped )

AFAIK, TA partition is where all ur DRM keys are stored. U can backup and restore the TA partition using Backup TA utility. (search on google/xda)
Warning: don't restore another Sp's TA partition as it will hard brick your phone.

Use the search function. And if you unlock the bootloader always keep a copy of your TA partition.

it is possible to lock it without a backup, is your camera not working anymore ?
You can try flashtool, BLU option tries to relock it if it's unlocked, theres a good chance you will brick your device!
Have fun

Are you sure this is good and/or informative advice? I thought a locked bootloader not finding valid keys in the TA will refuse to ever function usefully again - no boot, no fastboot, no flashmode, nothing, totally bricked, and no way to convert it back to unlocked and get your phone back.
I would like to know if I am wrong about any of that. And... it seems that I was:
** Correction - it is Ok to relock the bootloader without having the pre-unlock data in the TA partition
** Flashing in data from any other TA partition (some other phone) seems certain to brick the phone though.

I've never read about those damages but I read things like the known camera bug.
I unlocked my Z1 on .290 - the Sony release which fixed the problem (4.3). I flashed a Recovery and rooted it with it and my device is working like it was with a "untouched" ROM.
That's all I know.
We could wait for a dev to answer deeper questions.

Yes this absolutely fine and is what I did with my Z1, ie do not unlock until after the 290 update is applied - you will see that advice on the Sony unlock website. However if you want a TA backup you need to do that before unlocking as the unlock process will wipe the keys, and you also need root in order to make that copy. (let me know if I am wrong about that)
My process was to root on earlier firmware, copy the TA, update to .290, then unlock. After unlocking full root on .290 is easy with a custom kernel and everything is good: unlocked, rooted *and* working camera.
But you *will* need a copy of the pre-unlock TA partition to regain any of the functions that use the DRM keys if you decide to relock the bootloader later.
It is impossible to get the DRM keys back, and there is no gain from relocking without them, all you're doing is locking down the bootloader without enabling BIONZ, etc, but you can certainly run a stock system if you want.

Hello, yesterday I downgraded to rooteable 4.2.2 rom in order to backup TA partition. Once I had backup, I updated to 4.3 (290) and unlocked bootloader, then flashed recovery. With recovery was easy to flash superSu. Now I have "stock" rom with root and unlocked bootloader, but I realized that x-reality wasn't warking anymore (because of the DRM keys loss).
I tried to recover TA partition, but I caused a soft-brick, wich I only could solve flashing a 290 ftf through flashtool, but I lost root. My question is: It is possible to have root and DRM keys (TA partition restored)??
Thank you very much.

So, apart from losing x-reality and some Sony apps functionalities (which I dont care). Do you lose something else? I heard about losing bionz processor, but camera still works, then I dont know how far this is true.
The incompatibility problem of root and restored TA partition, is because flashing recovery (which modifies kernel) or supersu.apk it self?
Thank you VERY much!
You loose bionz, but not x-reality. I unlocked my bootloader and I have x-relity enabled.
Some ROMs won't have working camera, for example: android 4.4 KitKat ported from xperia z ultra GPe, and some other ROMs.

I can see that the x-reality option is still on menu, and you can enable/disable it, but it doesn't work. Before, I could see in the first second of picture showing how x-reality improves the image (its an effect that can be seen with the naked eye), this is not happening now. By the way, its for sure that bionz stop working? How could I take pictures without it?
Thank you

Not sure about bionz, but I guessed it as I had the x-relity option enabled. I can't tell if it works or not as I don't have camera (I'm using ported 4.4)
It would be nice of someone confirmed it.
Correct me if i am wrong.
Bionz is a service which improves the pictures after a shot, isn't it ?
Bionz and X-Reality are things u can't detect that easy like "oh that effect is from X-Reality" or something else.
I thought the main reason for not working cameras on other roms was that the dev's didn't apply those 4.3 changes :S

Bionz it's a image processor that includes xperia Z1, it process the pictures taken instead the cpu. I dont know if it's easy to detect if it's working or not. But in the case of x-reallity it's very simple, when you open a picture in Sony gallery app, you can see how the picture "improves" quality in the first second. It is no so evident in all pictures, but can be detected by a naked eye, as I do.
My only doubt is about bionz processor, I already know that I loss x-reality. But I want to be SURE if bionz processing is also lost. I want to have full root (with unlocked bootloader), and have bionz enabled. I dont care x-reality or Sony apps.
Thank you very much

Not true. If you have a TA backup, install .290, unlock bootloader, install a recovery, root, reflash stock boot partition, restore TA partition, you will end up with a booting, rooted, .290 installation.

If I received unlock code from Sony, unlocked phone via official way, than relocked bootloader and restored TA is there any way that service will detect if bootloader is relocked?

I think sony is only able to see especially if your request code!! but the operator does not see it because he lacks experience lool he does not know the word bootloader!
why this issue ??

I dont't think so, because you can request the code and never use it. Restoring TA brings the phone back to state like it was never unlocked. Nobody can tell if you unlocked bootloader or not. If you relock bootloader via flashtool instead via restoring TA backup, then they can tell you relocked it because your DRM keys will be missing. You are safe.

4 Install official firmware from here: http://forum.xda-developers.com/xperia-z/general/stock-xperia-z-c6603-10-5-0-230-central-t2759584

No is the simple answer.
I don't know if they have the tools to check such things, but they most probably will only check if official fw == 1 &if bootloader lcoked == 1.
I normal language: They will only check if you have official fw and if your bootloader is locked.
ok
is it normal that the "TA backup" is 160 kilobytes? i did a backup sometime ago.. but 160kb is not really much.. i thought it would be 800mb or something

hi, my z1 has a broken vibration motor. My phone is in warranty so i want to send it to repair. my bootloader is unlocked but i can re-lock it and i also have ta partition saved.
so can i send the phone without re-lock the ottloader or can i have problem with warranty?
if i have to relock it, can i relock it simply with flashtool o r i have to re-flash the ta-partition?

I'd give u a tip bro
Back up your current TA too with BL unlocked and save it in your pc, then restore your ta which is made before the first time u unlock bl, then flash a stock ftf and u go to sony.
When u get your phone back, get restore your ta from unlocked bootloader again, then u immediately have your phone unlocked again

u may unlock it yourself again, it will work as u expect but this way of unlock wipe your data and would take a bit more time
using the ta trick wont wipe it and it just takes 2 second, u dont have to type the unlock code bla bla bla

Is your bootloader unlocked? Is your phone C6902? Why in the world would you want to flash antiquated 4.2.2, especially if your bootloader is unlocked. The unlocking guide specifically states you have to be at least on 4.3 in order not to lose camera. If your phone is C6902 and you flashed C6903, you have a wrong baseband.
No. You can't use another phone's TA backup, unless you want to brick your phone.

I am not familiar with SOL23, but if your bootloader is locked, there is no permanent damage. You just need to re-flash the original firmware for SOL23. Try to repair it with Sony flashtool...
You have to restore your phone to original, then, if you want to unlock bootloader, do a TA backup, so that you can restore DRM function in case you would want to relock. If you unlock without backing up, you will lose your DRM key forever...
