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.

[Q] TA Backup before 4.3

Hi, This is probably a really stupid question but....
I'm currently on .257 with root.
If I backup my TA partition on .257 then flash 14.2.A.0.290 and unlock my bootloader. ( I then plan to root with unlocked bootloader)
Will my TA backup still work if I ever want to lock the bootloader again? (even if it means downgrading to an earlier version to obtain root again?)
Thanks

As far as i know the ta partition (alltough the backup) have no firmware version. So I think it will be possible.

[Q] restore ROM Backup with TA Partition

Hello,
i have an Firmware Backup from the Stock 157 ROM with TA Patition (ta.emmc.win, ta.emmc.win.md5) on my SD Card. I made this before i unlock my device.
When i would restore this Backup, is the Bootloader closed after this, or would my device Hardbricked?

No one an idea?

My advice, try to lock the bootloader first (Be sure to be on stock .157 before relocking and backup your SD CARD) then after that, restore your backup stock .157. Everything should work fine since you'd just relock your bootloader, maybe it will erase some data, but in my case after i unlock or relock my BL, no data was loss during the procedure.
For the TA Partition, have you made any backup using this method or any backup TA tool? I can't assure you if the DRM keys will still be intact in the backup ROM.

Sure, an Backup is already present at my PC. That was the first thing that I have do with this phone. I ask only if it possible with this way. I mean I have read last year an post from Doomloard. But I can't find this post.

Good! Relock using flashtool, restore backup then check if there are any issues, then finally, restore the DRM keys, just to be sure..

I think it is better I flash an complete ftf file an relock then... I don't need this backup anyone... Thanks for help.

Okay, just check first if the DRM keys are still intact after flashing the ftf, then closed this thread after if the problem is solved. thank you!

if u want to unlock bl: use flashtool
if u want to relock bl: use TA tool [if and only if u did a back up using TA and b4 unlocking bl]
BE ON STOCK FTF

Restore TA Partition

Hello so i unlocked the bootloader and checked the bootloader status which was unlocked but before doing it i backed up ta partition of my device. And to test it i restored it and checked again and it was showing bootloader unlocked allowed yes.
So I went ahead and unlocked the bootloader again tried many custom roms in a year.
Now after a year I am trying to restore TA partition with the help of backup ta tool but somehow I am getting error in restoring it.
So all i am asking is there any manual way to do it except for the software??

Tell us which error you are getting?
Are you already back on stock?
My feelings are that maybe you need to be on stock bootloader or kernel to restore your ta partition.
How you searched the TA thread for a solution?
