[Q] Unlock bootloader wipe TA partition ?

Hello.

Im abit new to the forum but here goes.

Ive read tons of posts everywhere and there aint any exact answers anywhere to find.

In the past ive never known about the TA and DRM so happy as i am i just unlocked the bootloader on all the phones and still happy. The latest phone is the Xperia Z1. It has been abit buggy to say the least but im hoping software updates will cure this.

Anyway, i rooted my phone and unlocked the bootloader on the .681 firmware and now i am on .757 firmware. Using Doomlords kernel. I thought id check if i could backup my TA partition after unlocking the bootloader. And from what ive read its suppose to be wiped when you unlock the bootloader.

Well it was no problem backing up the TA partion. All files were there and it came out with no errors. So the question, how is this possible ?

Aha, just wanted to sort things since ppl were saying that it was completely wiped when unlocking bootloader. And when I checked it wasn't.

Although, after numerous tests with the phone I can't understand what use the DRM keys is. Everything works just like it should without them.

Another question though. If I relock my phone with flashtool. What is the way to unlock it after? The official way won't work again I guess?

Ye updating with Sony software won't work nor the over the air update. But that's about it as I've seen.

But I remember on my Sony Xperia V that when I relocked it, then I could use Sony update again and I did so wiping everything before I sent that one to the repair shop. They repaired it and I got it back. All under warranty

The latest update .757 is really buggy, hope they fix it. Phone restarts sometimes when using the camera.
