Upgrade to Marshmallow or stay on Lollipop? - Xperia Z2 Tablet Q&A, Help & Troubleshooting

At the moment I am still, very happy, on my pre-rooted Lollipop stock ROM.
Is Marshmallow an improvement and should I upgrade?
If I upgrade, going back could proof to be difficult, so I ask here what are the experiences with Android 6 on the Z2 tablet?
Especially, how does the battery life of MM compares to LL?

[Q] are the OTA C6806 GPe updates still possible

Hi,
I recently got a new Z Ultra GPe as a replacement to my old one. I had OS version 5.0.1 before but the replacement I received is 4.4 and tells me that my phone is up to date. I expected I would get updates but that doesn't seem to be the case. Does anyone know if the OTA updates are still around and if I should be getting them by the normal method (rather then having to manually sideload)? For my needs I'm ok with a the non-rooted stock experience so I don't really want to deviate from that (and I don't really want to void my warranty as I have had to rely on that already). Any help is appreciated. Thanks.

I looks like the OTA was pulled (well no longer being pushed) just before Christmas. The 5.0.1 is a little buggy so I would stay on 4.4.4.
Also note that there is no safe way to revert to 4.4.x from 5.0.x unless you root on 4.4.4 and back up the TA.

Thanks, but I have 4.4 and not 4.4.4. Version 4.4 is super buggy and basically not usable. 5.0.1 was very usable in my opinion. If I can get from 4.4 to 4.4.4 that would be a great place to start. If I remember correctly there were three updates to get from 4.4 to 4.4.4.
If the OTAs are pulled, then why are phones with 4.4 being released into the users hands? I'll have to talk to google support about this. Is anyone else in the same boat I am?
Is only the 4.4.2 OTA not being pushed, or are all Z Ultra GPe updates not being pushed?
Thanks.

I'm not sure what ones aren't being pushed any more, but they were all still being pushed just before christmass. You could put 4.4.2 on a SD card and flash that from recovery and see if the 4.4.3 and 4.4.4 OTAs arrive, if not they are archived in the GPe section and I have copies here as well.
Either way I would root 4.4.4 and do a TA backup, it will give you many more options if you ever need to roll back for any reason.
Bugs of note on 5 are:
memory leak
some wifi issues for some users
I have micro hangs (may well be from the memory leak)
OK. Thanks. I am going to do the process here: http://forum.xda-developers.com/showthread.php?t=2761698 (different method but same result) to get to 4.4.2 and see what happens.

help for a good choice from newbie!!

Good evening to all forum..i've just bought this great tablet.
I did all the updates until you get to kitkat pero 'I read that consumes a lot of battery.
I would like some advice on how to fix it, if you go back to the previous update .... ... or put lollipop ??
Considering that I am a beginner and would like to make a few changes
greetings
The best version of android for this tablet is 4.3(SGP3xx_10.4.1.B.0.109),great battery life and really smooth. Lollipop just release yesterday so we have to test how it run for the moment.
Hello Borexz ... then back to 4.3 flashtool should I use?
Currently I also customization tim and I would take it off
Could you kindly tell the operations to do to get Android 4.3 Generic and where can I get the firmware right ?.
My model is SGP321
Best regards:good:
I have been using Lollipop and I must say that is the same or better than 4.3.I recommend just flashing lollipop,i downloaded from here and flashed with flashtool:

For now we have to wait for a version for the region, when will be available in XperiFirm.
Not everyone can use without risk of firmware for HK and TW.
I personally will wait for the recommendation of @najoor.
His great review "Xperia Tablet Z: The best stock firmware for power and performance" is impressive.

Marshmallow for s3 neo

Will be aveible marshmallow update for s3 neo?
Nothing official. If there are custom roms, they won't be based off of Samsung software and will be awhile before they're usable, much less stable (if ever).
Okey but will than a 6.0 update be aveible not offical?
Looks like there is still some development going on for your phone here on XDA, so most likely someone will try and make a version. When, and how well it works, depends on too many things to be able to predict at this time.

5.0.2 firmware dilemma

Hi all,
From the list of latest 5.0.2 firmwares on Sammobile which would be the best European firmware to flash my phone with? Preferably one without and carrier bloatware.
I'm currently on the latest UK BTU firmware but the battery life is shockingly bad.
Thanks.
My personal experience after testing lollipop is that any 5.0.2 version consumes more battery than any version of kitkat. Are you considering going back to kitkat along with a factory reset? Think of it.
Due to the security changes You cannot toggle mobile data (from widget, tasker, llama, power toggles) without rooting Your phone in 5.x.x. - because of that I decided to go back to Kitkat from Lollipop....funny, but true.
I don't want to go back to KitKat as I see this as a backward step really. All I want is a stable phone with good battery life (I know that's difficult on the Alpha though )
I was using 5.x.x for 2 months, it was stable just like KitKat. Battery life was worse, but I had mobile date enabled almost all the time, so can't really compare 1:1. For me, fact that You have to root phone just for ability to enable/disable mobile data from Tasker/Llama etc. was big backward step. I hope, that we will get Mashmallow soon (new permission system), but applications have to be updated to the newest Android SDK to work as described.

Still no Marshmallow ROM for OF1?

The battery drain of Lollipop is driving me crazy and since theres no way to go back to kitkat Im stuck with this so I wanna know if theres a way to update to marshmallow
There will be no way to go to marshmellow as there is no Sammy base to build on and there is no bootloader unlock.
Just go to Stang's Lolipop ROMs and get the modules which greatly helps with the battery drain.

even after sammy update all devices to marshmallow (S7, S6, Note 5, S5, etc.)?
Yes. They have dropped support for the s4. It's not that it can't run marshmellow so much as to get people to buy their latest phones.
