How can I make sure if the bootloader was unlocked successfully? I don't want to install a custom rom and find out that I actually didn't have an unlocked bootloader.
1. Dial *#*#7378423#*#* .
2. Go to -> "Service Info" -> "Configuration"
3. If there is:
- Bootloader unlock allowed - Yes << this means that your Bootloader is Locked
- Bootloader Unlocked - Yes << this means that your bootloader is unlocked
4. Enjoy
remember that backup your TA partition could help you to save your DRM keys
I bought used Xperia Z1, and today went to service menu and noticed the bootloader is already unlocked.
This is I understand should be procedure:
TA backup > Unlock bootloader > Root > Downgrade
question is can I still do TA backup now? knowing it already came with unlocked bootloader ?
P.S.
ver - 4.3 .136
root - no, (no SuperUser seen)
DRM keys -> present
You can check DRM status

Type *#*#7378423#*#* on your phone and go to Service Test > Security, if you have [Unknown Error] instead of [Key OK] they are lost, to restore them the only way is to use Backup of your TA. If you have all [Key OK] they are OK!

simple answer is no
You have wiped your ta partition when unlocking
however, there is no need to unlock the bootloader to root, just follow the link in my signature
also, you need root to backup the TA
And I bet your bootloader is not already unlocked, they do not come like that
dial
*#*#7378423#*#*
goto service info and configuration. Post what the last line says
I bet it says
bootloader unlock allowed: yes
That means you are able to unlock it, but it is not unlocked yet
If it was unlocked it would say
Bootloader unlocked: yes

Thanks for replying I am new to Sony phones, coming from Galaxy world !!!
here is what I get in service menu for DRM keys and Unlock bootloader (attached pics)
so this is what I understand: it is unlocked bootloader,
I can root it
I can install custom roms etc.
but incase anything goes wrong, I cannot go back and install stock rom, or downgrade from 4.3 (currently) to 4.2.2 ? and claim warranty ...

yes, just flash XZDR kernel from here http://nut.xperia-files.com/
http://prntscr.com/3nnvhr
Just extract boot img, flash using fastboot, then enter recovery and flash the whole .zip to get wifi modules etc
Then flash SuperSU.zip from chainfire
http://download.chainfire.eu/420/SuperSU/UPDATE-SuperSU-v1.99.zip
then enter philz recovery, goto philz options and tick "fix root on reboot"
reboot to system and fix root.
All done.
Yes you can flash stock FTF files and yes you can downgrade, but there is no point.
You can downgrade but do take not that sometimes you lose your IMEI when skipping major downgrades for example when you're on android 4.4 and you flash a android 4.2 ftf you'll lose your IMEI. Workaround is you have to flash android 4.3 1st before android 4.2
Hello,
does someone know if a TA-Backup (and restore) would be possible, assuming there will be a method to root the XP with locked bootloader?

Yes, I know. Already did that in the past with my Z1c, Z2Tablet, Z3c ... But somewhere in the Z5 forum I read that it won't be possible, even when geeting rooted with a locked bootloader!? So maybe Sony changed something regarding TA partition and/or DRM storage?
Dear Community,
I recently decided to unlock my bootloader and so I backed up my TA partiton/DRM Keys and went ahead. Today, I reflashed stock marshmallow to get rid of my custom ROM, and I re-rooted so that I could restore my TA partition. I restored my TA partition via the Back-up TA v9.11 tool, that completed successfully, but I'm unsure whether my bootloader has now been locked, or if it is still locked. Does restoring the TA partition automatically re-lock the bootloader or is an additional step required?
My aim for the whole process was to lock my bootloader and flash the Concept software?
P.S. In my device config settings it now says 'Bootloader Unlock allowed: yes'.
Thanks in advance.
