Requirements:
Flashtool 0.9.15.0 or higher
Rooted SGP311 (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.

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 SGP311_10.5.1.A.0.292_Customized_XXX.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 and wait for the white LED to blink 3 times (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 SGP311_10.5.1.A.0.292_Customized_XXX.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, make sure it is off, then hold the volume down button and then connect it with the USB cable to the PC.
13- Reboot. You are now on rooted 4.4.4, firmware 10.5.1.A.0.292.
Battery Drain Issues
Please note that, according to Sony, any firmware shipped with Google Play Services version 4.4.52 has a battery drain issue ( http://talk.sonymobile.com/t5/Xperi...-Drain-issue-Workaround-Fix/m-p/708273#M42303 ). This problem has been known since around June and surprisingly Sony has not updated the Play services in this firmware. To avoid battery drain please update your Google Play Services as soon as you are done flashing.
