Hi guys is there a tutorial on how to restore my TA backup, i know you use the backup TA tool but not sure what to do
i have a backup TA zip file, and a TA img file.Do i have to be on stock firmware? rooted?
my bootloader is unlocked and rooted at the moment running eXistenZ 2.0
thanks.
What did you use to backup TA? I would hope that tool would allow you to restore it. If not you can restore it using flashtool, the option is under advanced >restore trim if memory serves me.
i used the TA backup tool, do i need bootloader locked or unlocked to restore TA backup?

Done it, flashed stock rom, rooted stock, used Ta backup tool to restore TA file, sorted...

Hi,
i upgraded to the latest Build 23.0.1.A.0.167 and lost root. I have done a TA partition backup on Version EURO-LTE_17.1.A.2.36.
My question is: If i flash a rootable ftf file with flashtool now, how is the TA partition affected? Could i proceed without losing the TA partions DRM information? Or should i restore the TA partition backup afterwards?
My plan is to downgrade via flashtool and a rootable ftf file. Apply root and upgrade to the latest firmware via recovery.
Thx in advance.
Solved. I didn`t know that as long as your bootloader is locked, the TA partition isn't affected.
So, I had my bootloader unlocked back when I was in kitkat (unsure whether I had version 4.4.2 or 4.4.4), but I had backed up my ta partition in case I wanted to relock the bootloader.
Fast forward to today, I am on lollipop (version 5.1.1) and I want to relock my bootloader. Note that I am on stock kernel.
Obviously enough, I have to restore my ta backup.
But I have some questions.
1)Do I have to downgrade to the android version the phone had when I took the ta backup, or I can simply flash the ta backup on my current android version?
2)During this procedure, does anything (such as data) get wiped?
3) Will I lose recovery during this procedure?

Click to expand...
Click to collapse
1. no
2. shouldent be
3. if you are using recovery for locked bootloader then no
A few days ago this was released: Universal TA partition backup
This means that we can retrieve the TA partition with a LOCKED bootloader!
In theory, then we can save the TA partition, root the M4 after UNLOCKING the bootloader, and then relock it by flashing the TA partition back.
If you were wondering about DM-verity, the M4 doesn't enforce that.
Someone confirm this?
Is no one seriously going to try this out? Fine I'll try it in my own time...
I tried it last week and it doesn't work, the backup file was 0bytes. Anyway you can make a TA backup using TA backup master with downgrading to Lollipop, root using the known exploit and then unlock the bootloader.
To root on MM you have to flash boot image, which requires unlocked BL and re-locking after that will result a boot-loop.
Check out the new version. It works now. TA Dumped ^^
The main problem is still there, flashing SuperSU from twrp doesn't work, so no way for re-locking the BL with root after that.
So I don't know if the title is confusing
The question is rather simple
Can I restore the backup taken while on LB and flash them back after unlocking my bootloader ?
It will work right?
Not for TA partition.
