[FTF][4.2.2] Xperia Tablet Z (SGP321) 10.3.1.A.0.244 Global Unbranded

[lowtraxx]

I built the ftf with Sony Bridge and flashtool 0.9.11.0 and flashed it successfully. This is ONLY for 16GB Xperia Tablet Z LTE (SGP321). Other than that, no warranties.

How to root 244:
I am not responsible if you attempt this and something breaks

1. Flash 307 and root it
2. Back up the TA with tool from here
3. Unlock BL with Flashtool
4. Update to 244 with Flashtool
5. Boot from CM10.2 boot.img (Can be taken from any CM10.1 or 10.2 ROM or for your convenience from here) into recovery by selecting Flash -> Fastboot Mode -> HotBoot Kernel (Sometimes this does not work, if so unhide steps 5a and 6a otherwise continue)

5a. Flash CM10.2 Recovery in console with

fastboot flash boot boot.img

6. Apply SuperSu via update.zip (Superuser does not work as it seems to not support the new User Management feature permissions of 4.2.2)

6a. ReFlash 244 but without wiping data and excluding system partition from the flash

7. ReLock BL with Flashtool (This step may be unnecesarry, because the backed up TA relocks the BL as well)
8. Restore the TA from the backup

Its a little inconvenient, but it worked for me, and now I am rooted an still have all my DRM keys

I get this strange All checkpoints reached in the taskbar? Is it removable somehow?

Sorry as second reboot removed it.

You did not reboot the tablet once it told you so after the initial startup, didn't you
Just go to Settings -> Apps -> Currently running and kill the sony startup service. It will tell you its dangerous to do so, but do it anyway, as it is finished doing what it was supposed to do.

Can you make kernel as ftf to flash it separately in order flash it after rooted with older kernel.

I tried with the older kernel from the 307 ftf, but they are not compatible (Tablet will not boot) So rooting is a no-go ATM (unless your bootloader is unlocked) because there is no older 4.2.2 thats rootable for the Tablet Z.

so do i. Flashed kernel from 307 firmware. Got bootloop. Now flashing to 4.2.2 again.

This method is not working properly cause old kernel for smartphone was already for 4.2.2 and we don't have rootable kernel for tablet z.

I think it's easier to get root on .307 firmware, save it with OTA Root keeper and then update to 10.3.1.A.0.244 with pc-companion and restore root.

Yes it is, if you already are able to update via PC Companion. This is more meant for people that do not see the update and want to get it via ftf. Or are you able to update as soon as 244 was present on your device once?

Is this way can do with Locked Bootloader users?

the update is available for me via pc-companion from 05.08.13. As far as i understood pc-companion performs update without wipes, so all user information is untouched and therefore root can be saved.

yes.

Yes it is. See post #11

But if you stay unlcoked it should be even easier.

1. Get yourself a boot.img with attached recovery (CM 10.1 for example)
2. Use flashtool to fastboot the boot.img as temporary kernel (not flashing, just booting)
3. Press Vol Up to get into recovery
4. Flash SuperSU

Are there still reboots when you try to mount /system as rw with locked bootloader?
@lowtraxx: you don't need to relock the bootloader with flashtool because if you flash back your ta backup it is locked again. I'll also flash back my ta when the wifi version of the 4.2.2 update will be released. Now i am on cm10.1

Just tried a

su
mount -o remount /system
cd /system
ls -l

after 2 minutes still no reboot. So I guess it does not.
