<SOLVED>[Q] TA backup with firmware 14.3.A.0.683 (Sony Xperia Z1 C6903)

kentexcitebot · Mar 31, 2014

Hi,

I'm trying to backup the TA on my Xperia Z1 (C6903) running the stock KitKat firmware (14.3.A.0.681). From what I understand though, you need root to backup the partition, but to get root, you need an unlocked boot loader. I've seen a few tools that roots without unlocking the boot loader, but I need to downgrade the firmware to at least Android 4.2.2. Downgrading requires an unlocked boot loader.

Are developers working on a root-and-unlock tool for 14.3.A.0.681? Is there already a tool out there?

Thanks in advanced. Sorry for my arrogance.

You do not need an unlocked bootloader to get root and or to downgrade. Although yes, you would have to downgrade to 4.2 to get root. Just use flashtool to downgrade and pick a software to root

Cool

Just a couple more questions. Any suggested 4.2.2 and 4.4.2 firmwares to flash (if you can, link them here)? To root 4.2.2, do I simply click on the unlock icon shown in link?

I've used vroot 1.7.3 english and everything installed fine. However, when I installed the Root Checker app from Google play it reads "Sorry, this device isn't properly rooted."

Here's what I did / planning, in order:

1) Downloaded C6903 14.3.A.0.681 Global 1277-2880_R5C
2) Downloaded 14.1.G.1.534 downgrade FTF [NUT]
3)Pasted the 2 FTFs in the Firmware Folder under Flashtool
4)Flashed 14.1.G.1.534 downgrade FTF [NUT] using Flashtool from Androxyde (latest version)
5)Installed vroot English (1.7.3)
6)Clicked on the Root button. Phones reboots twice
7)After phone first start I was greeted with an error message from "Kingsapp".
8)Installed Root Checker from Google Play
9a)"Not properly rooted" <-- I'm right here
9b)If "root successful", proceed to flash C6903 14.3.A.0.681 Global 1277-2880_R5C

I did some research and people are pointing everywhere, vroot, bin4ry's rooting method, 360 (can't install).
Did I lose my TA partition? My X-Reality goodies?
What am I doing wrong?

Okay so now you are still on .534 firmware right? Do you have usb debugging on?
And also try rooting with bin4ry if vroot doesn't work for you.
Don't worry, you won't lose x-reality unless you've unlocked your bootloader

"Su upgrade failed. Missing root permission"
Yes, I'm on the .534 firmware. USB Debug turned on.
I'll try bin4ry's root now.
Once I'm through TA backup, I just need to flash 14.3.A.0.681 Global 1277-2880_R5C?

If you still can't get root, try using nuts z1-lockdualrecovery installer and after flash nuts .681

I was able to root and deodex the Kitkat rom.

Xreality and other goodies working just fine.

Thanks so much
