[Q] Xperia SP 4.3.3 Root Keeping DRM Keys - General Questions and Answers

I have an Xperia SP currently running 4.1.2 rooted, bootloader locked.
My aim is to upgrade to 4.3.3 and root, for which i will have to unlock the bootloader. To do so I need a TA partition, for which again, root is required.
So, my question is that is it okay if I take a TA Backup now [in 4.1.2] and then upgrade OTA and unlock bootloader, root and then restore the 4.1.2 TA backup onto 4.3.3 in order to restore DRM keys and Relock the bootloader?
Has anyone done this?
is it safe?

[Q] Backup TA @ Android 4.2.2

As far as i know there is no way to gain root on 4.2.2 without unlocking my bootloader.
I want to backup my TA so i guess i need to go back to 4.1 (via Flashtool) then gain root through motochopper then backup my TA. Than go back to 4.2.2 again and than unlock my bootloader in order to gain root on 4.2.2
Can somebody confirm if this works and does somebody have a ftf file with 4.1 Jelly Bean?

Flash 4.1.2(there are some ftf in general tab) then root, backup your TA partition,unlock it and then probably you will get bootloop,just flash 4.2.2.Then use what method you want to root 4.2.2(like flashing .zip or manual push)

Thank you!
EDIT
I can succesfully confirm that i have root on 4.2.2 with a locked bootloader!

No
Unless you made a backup before unlocking the bootloader you have lost your DRM keys forever.
Relocking the bootloader and Re-flashing a new ROM (even from other countries) wiping all (data, dalvik, etc) worked for me, tried this on my Xperia SP and Xperia Z2. Because the new TA partition is included on most firmwares...
Try to flash a 4.4.2 ROM (or any locked bootloader rootable), to be able to backup your new TA partition...
OR
Try this method :

Incorrect.
The DRM keys are NOT included in any FTF. If they are lost they are gone for good.
There are some methods about that partially restore some of the functions that require on DRM keys, but they are not 100% the same as having the keys
There is no point backing up the TA once you have unlocked.

I am running CyanogenMod now and need to go back to factory software (locked bootloader with the TA restored). I have got an old firmware (4,4,2 Android), but it includes the TA. I already made a TA backup myself, but what to do: flash the stock ROM with the TA and than restore my backup or should I not flash the firmwares' TA but only restore my TA?

Restore the TA and flash a stock FTF with flashtool before you reboot.

Lollipop - Unlocking bootloader and rooting

Hi
I am on the newest firmware (5.1.1) and i want to unlock bootloader and then root my M2. So... Should i return to 4.3.3* (KK or JB) to unlock bootloader? After UBL i can use tutorial for root (i saw it here) or i have to make some other steps?
*i saw info that its better when we unlock bootloader on JB/KK because of partitions (???).

Help needed to reset back to Stock

Hi
I am running Xperia Z5 (E6653) unlocked bootloader, Stock MM (32.1.A.1.185), modified stock kernel (only added SuperSU, TWRP, DRM Fix).
Is there any way I can go back to stock Lolipop (stock MM will also work).
Edit: What steps do I need to restore TA partition and relock the bootloader?

you can use flashtool to download a firmware (XF icon) and from there you can flash a stock kernel and presumably you could use the tools you used to backup your TA to restore your TA which would lock your bootloader

PLS HELP Rooting Xperia Z5 [LB]

Hey!
How can I root my Z5 which has a LOCKED BOOTLOADER. I don`t want to unlock the phone, did that with my Z2 and wasn`t worth it until the final Android Version has arrived.
Specs:
Z5 E6653
32.2.A.0.305 / R9C STOCK
Locked Bootloader
No Recovery
you only can get not full function root with LB, but you can use it to backup your TA.img, then you can unlock your BL, when you want drm back, you just restore them
