Xperia Tablet Z 4.4.4 KitKat Rom - Pre-rooted - Includes Recovery
For SGP311 and SGP312 - Wiping is optional​

** DISCLAIMER: I AM NOT A DEVELOPER. I DO THIS AS A HOBBY AND SHARE MY FINDINGS IN CASE SOMEONE ELSE FINDS THEM USEFUL. **
** THIS WORKED ON MY DEVICE BUT IT MAY NOT WORK ON YOURS. APPLY AT YOUR OWN RISK **​

Requirements:

Flashtool 0.9.15.0 or higher
Rooted SGP31X (on any other previous Android version) with custom recovery (i.e. XZDualRecovery) installed.

Previous firmwares up to 4.4.2 can be rooted with towelroot.
If your current Rom doesn't have recovery, follow step 10 of this post: http://forum.xda-developers.com/showpost.php?p=53063218&postcount=14 with tablet in USB debugging mode (step 4 of the same post).

This works on locked or unlocked bootloaders and any customization.

This ROM is pre-rooted and comes with recovery. Other than that it is identical to stock rom.

SGP312 US_CA_PR https://mega.co.nz/#F!El8QnQxC!BlkadNT5FWGF3dLfCbD4mA

Use the link that matches your tablet model. You only need the zip and ftf files. The txt file is just the checksum if you want to verify that your download is error-free.

Instructions:

0- Backup before you start messing with your tablet!

1- Put system.flashable.zip in /sdcard of your tablet.

2- Keep SGP31X_10.5.1.A.0.283_VMo US_CA_PR_NoSystem.ftf on your PC.

3- Disconnect any USB cable that may be attached to your tablet.

4- Reboot to recovery. Preferably to TWRP, but you can make CWM work too.

5- Do not wipe anything.

6- Once in recovery, flash system.flashable.zip.

7- It is important to TURN OFF the tablet after this step.

8- Find and use the Power Off option in the recovery and turn your tablet off. In CWM based PhilZ Touch it is under "Power Options" -> "Power Off". In TWRP it is under "Reboot" -> "Power Off". If you see your tablet rebooting, force it to turn off by pushing the power and volume up keys simultaneously (or however else you can!)

9- Open Flashtool 0.9.15.0 (or higher) and click on the flash icon. Choose flash mode.

10- Navigate to where you have saved SGP31X_10.5.1.A.0.283_VMo US_CA_PR_NoSystem.ftf

11- If you do not want your any of your current data to be wiped uncheck all the items under the "wipe" section. My recommendation however is to wipe.

12- Now flash this ftf with your tablet in flash mode. To put your tablet in flash mode, hold the volume down button when it is off and connect with the USB cable to the PC.

13- Reboot. You are now on rooted 4.4.4.

Can I flash this on SGP312?

 

[nick2crete]

Kindly request if you could make also a flashable zip with any European rom

You can and it is not going to break your tablet but there are small differences between the two fimwares. I added a link for SPG312 too.

I can try when I have time. PM to me your model and your customization code.

Flashed and works good on SGP312
Thanks!

 

[nick2crete]

It worked perfect !
Thank you very much !

I wasn't going to update to 4.4.4 until you offered this solution. Swapping kernels,etc., re-rooting, reinstalling recovery was just more work than it was worth and had the potential to brick the device. Your approach is brilliant! Thank you very much.

However, I am not able to boot into recovery.

Thank you very much for the easy-to-follow instructions.

It worked perfectly on my SGP312. Fully rooted 4.4.4 Kitkat.

Working on 311

OP!!

Any chance that you can and will release a 10.5.1.A.0.283 deodex package for 311 / 312 versions / firmwares?

How is it performing for you compared to omni rom?

I wouldn't be able to compare it to Omni as I haven't used it. Actually, I havent used any AOSP 4.4.4 version. But I can say that 4.4.4 stock so far it has worked pretty well.

• There's no lag anymore in the options menu.
• Battery seems to last as much as it did on 4.4.2, but I'll update this info after some more testing.
• Stock launcher feels smoother, although I use Nova Launcher Prime.
• I haven't noticed any bugs for now. Perhaps the only thing is a quite short, recurrent distortion in the sound when playing music, but I had that issue in 4.4.2 as well. Haven't found any info on that.

I'll try to report more as I continue using it.

Tanks man for the feedback. Will you be re-locking the boot loader for the DRM xperia engine, is that possible?

I am really glad that we have this option available to us now

yep! it's possble with BackupTA.

 

[cantenna]

I'm surprised to hear there is occasional static sound with a stock ROM from Sony. Can you pleas elaborate as to the problem?

Also, if I follow this tutorial will it automatically relock my boot loader? I'd prefer to keep an unlocked boot loader until I have had opportunity to test drive.

I'm very pleased with my Omnirom ATM. Am curious to try though.

Thanks

Not completely related to the OP, but this is the first time I've upgraded a device that I had encrypted. Following all the steps, my device is now stuck in a bootloop. TWRP is unable to mount the encrypted partition w/ the passphrase I had set.

Anyone else experience this, or better yet have experience with this in general?

Sorry, I do not and I have not tried this ROM yet

I got my stock 4.4.4 rooted, but unfortunately not with this ROM. Below are my thoughts on what the problem may be.

system.flashable.zip only includes TWRP 2.6.*, which apparently has issues mounting encrypted partitions. These issues are solved in TWRP 2.7; can the OP update system.flashable.zip to include 2.7?

For those who still want to use this ROM, after flashing system.flashable.zip, I'd immediately install dual recovery before rebooting. I've not tested it myself but it's my theory for what will work.
