[LolliPop][Prerooted flashable zip][23.1.A.0.690][Z2 tablet SGP511]

[Buggedout]

I'm having problems with this. For some reason I cannot turn off or restart the device without hard resetting it.

I get the circle rotating as if it want's to shutdown but nothing happens.

This isn´t normal behaviour of this device or firmware. Did you dirty flash? Perhaps easiest way to try fix this is make a backup of your data and reflash prerooted firmware with factory reset and wipes. Or you can try to find out which app/process is it that actually prevent your device to turn off or reboot.

Hi

Here is flasable zip file wich install latest ROM 23.1.A.0.690 which is LolliPop and region is customized NCB, latest stable SuperSu v2.46 and latest fully working Dualrecovery 2.89 for Tablet Z2 with read and write acces to system.

Make nandroid backup before flashing.
Install it by flashing whole zip file with custom recovery TWRP recommend.
Factory reset is to recommend.
Here is the link:https://mega.co.nz/#!YFRUjRDT!L4-3ytDDfA-FT1jJlFa6RwXy7p2mL5uf3MohigDU-5U

If you allready are in LolliPop firmware without working recovery you need to downgrade you firmware first to rootable firmware.
1. Download rootable .314 firmware here: https://mega.co.nz/#!kcxxjaLA!itErjRi2fYPPswal-c7XasF_lAvPKyY4GwEzY3xgHZ0 and flash it via Flashtool.
2. Root your device with tool you choose. (Dualrecovery installer option 3, Easy Root Tool, Giefroot or other).
3. Install SuperSu to your device from Play store if your root tool don´t do it.
4. Install Dualrecovery with installer if you haven´t allready.
5. Resume your KitKat nandroid backup with custom recovery.
6. Flash prerooted .690 firmware with custom recovery.
7. Before booting up wipe cache/dalvik cache.
8. Boot your device and you are done.

Weird. Works just fine here with Firefox and Chrome. Try with different browser.

Hi !
Thanks for your answer. I tried the last firmware you posted, but I have a little problem.
I'am on 4.4.2 (17.1.a.2.69) rooted and when i try to install any zip with teamwin recovery all works fine. The tablet reboot, I see the first screen of the install guide (where you choose the language), but even i tap on the screen , a pop-up appear "infortunatly the setup guide crashed" and reboot.
I made factory reset before flashing, wipe cache and dalvik cache. Downloaded the firmware too times (i'm sure it's ok), flashing the bootfix.
Maybe I miss something.
Sorry for this basic english

You could try to wipe dalvik/art cache, system, cache and data in twrp and then before rebooting flash new firmware again.
