Hi, I never root at unlocked bootloader before. May I know where you get the SU.zip and root binaries as well BusyBOX. Any issue on CWM recovery after you restore back the TA?
new firmware arrived for xperia z c6603 (update 05/14/13)
- Thread starter elroy944
- Start date
SuperUser.zip can be found on this forum, please search for it. (use Chainfire version)
BusyBOX from play.
CWM can be reinstalled after rooting.
TA backup must be done before BL unlock, root is required.
Open terminal:
Type SU, hit enter
Backup: dd if=/dev/block/mmcblk0p1 of=/sdcard/ta-backup.img
Restore: dd if=/sdcard/ta-backup.img of=/dev/block/mmcblk0p1
TA img will be saved on SD.
And..playing with TA can hard brick your phone.
I tried it two times and everytime i got a softbrick (refuseboot) after restoring TA.
I think its caused by the Advanced Stock Kernel.
How you have done it?

You need to backup TA before unlocking BL for the 1st time.
1. Root is required on the current device, 434ver, terminal emulator too.
2. In terminal type SU, grant access in the popup window.
3. Type dd if=/dev/block/mmcblk0p1 of=/sdcard/ta-backup.img
"Backup: dd if=/dev/block/mmcblk0p1 of=/sdcard/ta-backup.img"
"Restore: dd if=/sdcard/ta-backup.img of=/dev/block/mmcblk0p1 "
4. Copy ta-backup.img on the computer too (please check MD5, i never did this but it's important)
5. Flashtool: flash new ROM (i didn't turned on my phone after this but it doesn't matter)
6. Unlock BL with FlashTOOL
7. Flash AdvancedStockKernel (i've used the one provided in link even if it was for 434)
8. TurnOn the phone, press vol- until CWM will pop.
9. Flash SU.zip
10. Open FlashTool again, select the new rom but uncheck everything except KERNEL
11. On your phone you have the option to reboot system (CWM menu), do it and press V-
12. Flashtool will start flashing the kernel
13. Start the phone, open terminal and use restore ta in terminal:
dd if=/sdcard/ta-backup.img of=/dev/block/mmcblk0p1
You will have the new room with root and BL locked again, BE&DRM intact.

Exactly, when TA is restored only stock kernel will work.
Yes.
But you can root it again if you can unlock BL and rerwrite TA back.

Hi, need your favor, last question, I had backup my TA in previous .434 firmware. It is same as current .253 firmware right? In-fact now version .253 also cannot backup due to no root right.
One more question.
Will it brick my device if I update, because i got root and CWM installed?

First you can't even restore it as there's no root for 253.
Secondly, Do not ever try to restore different fw backups to avoid any bugs technical difficulties.
If you have a locked bootloader, you can update and you will loose root and cwm.
Unlocked bootloader, you won't even be able to update until you relock it.
So both options you can't brick your phone.
OK finally its not a good way.
Root is broken with this method.
TRWP freezes and i cant copy files in root directory without automatical reboot from the phone.
Tried it 3-4 times this way, tried superuser insteed of supersu, but there are still this problems.
I've used SuperUser.zip and CWM not TRWP.
After booting up i've installed SuperSU and uninstalled SuperUSER.
I got 3 or 4 reboots when trying to uninstall some bloatware like sonyselect but after that everything is running fine.
I tried BOTH, CWM, TRWP, SuperSU and SuperUSER, but all the same bugs.
On 434 with Root (Superuser) i havent any reboots, all have worked fine.
With this setup i cant flash Docomo Statusbar without getting a bootloop.
