All seems good so far but will keep an eye open for anything odd.
[Xperia Tablet Z Original Android Development] manicmarvin:
Running the 27th build on my pollux_windy since yesterday and everything is great...seems even faster than previous builds as well.

Have a great, well deserved holiday qsnc...you've earned it. Thanks
[Xperia Tablet Z Original Android Development] Teella:
Installed the 27th build. Did a factory reset and clean install. Can't boot into TWRP 2.8.5.0. The violet light comes on, but pressing the up volume does nothing.

I tried to reinstall TWRP via android terminal with

dd if=/sdcard/Download/rom/openrecovery-twrp-2.8.5.0-pollux_windy.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel

I also tried NRDUtils and no boot into TWRP. Any suggestions?

Edit:

I installed TWRP Manager from the playstore. It saw I had 2.8.5.0 installed, so I selected pollux_windy and version 2.8.5.0 and told it to install anyways. After a moment a message comes up saying installation failed, do you wish to reboot into recovery? I clicked OK and rebooted into TWRP.

Now rebooting and pressing the up volume works.
[Xperia Tablet Z Original Android Development] BlackAfghan:
I think this is related to the introduction of the new sensors's API. The detection of the volume key during boot, depends on the old drivers. Directly rebooting into recovery should work, however.

But it works with the EvoMix kernel? I included a fix for that.
[Xperia Tablet Z Original Android Development] Teella:
I flashed the EvoMix kernel at it works flawless :) awesome thx!
[Xperia Tablet Z Original Android Development] jimh:
I have been unable to get this installed on my 312.

I followed the steps in the CM wiki but even though Fastboot seems to work correctly and shows up the device I can't get the boot.img to flash. it always fails with a "command not allowed"

I managed to install TWRP anyway and flashed the boot.img that way but it would not boot into recovery then.

If I simply try and flash the CM rom from TWRP I get an error saying it is Pollux not Windy Pollux.

I tried following a couple of suggestions that you can edit this in the zip file but noting works for me.

Anyone got any suggestions?
[Xperia Tablet Z Original Android Development] InteliDroid:
This is because the bootloader must be locked. Did you flash stock lollipop?
[Xperia Tablet Z Original Android Development] jimh:
I unlocked the bootloader using Flashtool which appeared to work fine. Is there some way to confirm that the bootloader is unlocked?

Yes,

I have flashed Lollipop and currently have the pre-rooter one on
[Xperia Tablet Z Original Android Development] andyvdsteen:
Are you 100 % sure you flashed the correct recovery/ROM? There is a difference between pollux and pollux_windy.
[Xperia Tablet Z Original Android Development] jimh:
I'm certain that the dual recovery works OK because I was able to flash the pre-rooted Lollipop with it, no problems at all.

This same TWRP will not install CM though as it always gives the error message about Windy pollux and from what I have read I have to follow the CM wickie instructions and use their recovery via the Boot.img file.

I just can't get this to work.

TBH I would be happy to get it installed using either method but I'm obviously missing something?

In summary:

Tablet Z 312 = 32gb storage version Wifi only

Bootloader unlocked

TWRP working but will not flash CM due to Windy-pollux error

Unable to Fastboot boot.img file due to error message
[Xperia Tablet Z Original Android Development] Essentrix:
Anyone else have problem of program unable to access external SD card?

It's OK now. Had to edit the permissions file and now all good. It's only an issue with the latest ROM.
[Xperia Tablet Z Original Android Development] Teella:
I clean flashed the latest 12.1 since I came from the 12 nightly. External SD card no issues :)
[Xperia Tablet Z Original Android Development] Essentrix:
I had no issues accessing the SD card but did you try using an app with data stored on the external card? That's where I ran into an issue. As I said, changing the relevant permissions file fixed it. :)
[Xperia Tablet Z Original Android Development] Teella:
Yes and as I said no issues :D :)
[Xperia Tablet Z Original Android Development] Essentrix:
Glad it's working for is both... :)
[Xperia Tablet Z Original Android Development] mrjayviper:
am I able to lock my display to portrait like in cm11? thanks :)
[Xperia Tablet Z Original Android Development] Teella:
Oh I was wrong :) I was going through my titanium backs and saw I had SDCardFix by NextApp, I'm sure I ran it.

[Xperia Tablet Z Original Android Development] 3vilArt_:
i flash boot.img from this ROM .. and now my tablet won't start ,, it also seems not charging and my pc doesn't recognise it , even flashtool

My Tablet status when flashing the kernel :-

Unlocked bootloader

running on stock sony lollipop ROM

90% Battery

Thanks :)
[Xperia Tablet Z Original Android Development] scoobyjenkins:
Won't it go into fastboot mode? If it will, try flash the boot.img from last omnirom (doesn't matter if it's kitkat) to get TWRP recovery, then try boot to recovery with vol button press on boot, wipe and install. Maybe leave charger plugged in for a bit first, even if it doesn't seem to be charging, hopefully it will. You can use fastboot with flashtool.

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] 3vilArt_:
Nice! thanks for replying :) .. i charge the tablet for 3 hours and i saw the notfication LED lights up , with RED light . the red led light remains light up even if i detach the usb . still my flashtool wouldn't recognize the tablet . hmmm ..:crying:
[Xperia Tablet Z Original Android Development] scoobyjenkins:
Ok, try this. I've found if you hard reset when charger is plugged in, it turns off instead of rebooting (at least my Pollux_Windy does!) So, try pressing vol+ and power together for a second or 2 while plugged into charger, then unplug the charger and see if the led goes off. Then try hold vol+ while connecting to a PC and see if it goes into fastboot mode.

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] 3vilArt_:
Thanks ! your method work ! May god bless youuu :) :)

[Xperia Tablet Z Original Android Development] Electronic Punk:

Success :highfive: - copied CM12 zip & gapps zip to internal SD, flashed boot.img via fastboot, then installed zips via recovery. All done in about 5 minutes !

Just as I finished, all the power went off in my area - 900 homes cut off :eek: Back on now.

Thanks for your help :good: I'm obviously getting out of practice with my flashing...
[Xperia Tablet Z Original Android Development] Rox598:
Glad you managed it chap. Has to be said the way you have to do this stuff on Sony devices is a bit messed up when compared to other devices. (Although from what i've heard HTC can be more risky)
[Xperia Tablet Z Original Android Development] SnZ:
From the moment I saw CM I knew it will not work lol :). Omni is doing fine job and I'm starting to use more stable devices, because every time anything else is mostly play thing for a bit of time (also do not want ART).

Still, OP delivered very nice working ROM :).

I remember when my first play with HTC Sensation fresh from box resulted in hard-brick so I approve this :p
[Xperia Tablet Z Original Android Development] themono:
Just to echo others sentiments here, incredible ROM. Silky smooth. Great job.
[Xperia Tablet Z Original Android Development] moesus:
Google maps doesn't find my location. Weird, because other apps do.

Anyone else having this issue?
[Xperia Tablet Z Original Android Development] Electronic Punk:
Looking forward to giving this a go.

For anyone hunting, found the google apps for cm12 here:

https://s.basketbuild.com/gapps

Anyone got any screenshots to whet my appetite?
[Xperia Tablet Z Original Android Development] halomademeapc:
I cannot, for the life of me, figure out what I'm doing wrong here.

Coming from the AOSP 5.0 build, I did

adb reboot bootloader

(extracted the boot.img from the zip)

sudo fastboot flash boot boot.img

sudo fastboot reboot

Then when I try to enter recovery by mashing vol+, the light turns pink, then orange and nothing happens. The screen stays fully powered off and the recovery doesn't load.

If I flash the boot.img from the AOSP 5.0 build, I still can't enter recovery, though the ROM itself boots perfectly fine.

Somebody please tell me I'm missing something simple here.
[Xperia Tablet Z Original Android Development] Shanliang-:
Perhaps you can try flashing a boot.img from a CM11 build to access recovery, and from there install CM12 zips.
[Xperia Tablet Z Original Android Development] andymg350:
You could try xzdualrecovery it seems to work for me on cm12 but not aosp
[Xperia Tablet Z Original Android Development] halomademeapc:
tried that too, no dice.

I looked at the thread and they provide a zip. Any way to install this from fastboot?
[Xperia Tablet Z Original Android Development] Shanliang-:
I think the easiest way to go is flashing a stock firmware through Flashtools, then using the installer provided by the dual recovery in that zip (this zip to be precise). Then you'll have no problem accessing recovery. When I'm always having issues like yours, I'd do the flashing a stock firmware method and go from there when nothing else works.
[Xperia Tablet Z Original Android Development] Essentrix:
Nice snappy ROM; any way to add/delete toggles?
[Xperia Tablet Z Original Android Development] bjrmd:
I am currently on the latest rooted stock and have the dual recovery installed but still have a locked bootloader. Do I need to unlock the bootloader first to install this or can I just flash the zip from recovery?

Thanks
[Xperia Tablet Z Original Android Development] andymg350:
You must unlock your boot loader first as the ROM uses a custom kernel, flashing while still locked results in a soft brick I think?

But don't forget to do a TA backup first so you don't lose DRM keys
[Xperia Tablet Z Original Android Development] Lupin The Third:
No. There is no ROM for lollipop with that mod...
[Xperia Tablet Z Original Android Development] Essentrix:
Thx mate. Give it time I guess... ;)
[Xperia Tablet Z Original Android Development] Charsher47:
I had the exact same problem when coming from AOSP 5.0. I flashed every kernel and recovery I could get my hands on but either the recovery wouldn't load or it wouldn't let me flash anything useful. Only solution I found was to flashtool back to stock, fastboot flash the cm12 boot.img, wipe data, and install as usual.

HTH
[Xperia Tablet Z Original Android Development] halomademeapc:
I did the same thing to get it to work.

I was unaware that cm has their own recovery now. Is there any way to disable verification in it? Also, is su working for anyone?
[Xperia Tablet Z Original Android Development] Charsher47:
Just enable it in developer options :good:
[Xperia Tablet Z Original Android Development] halomademeapc:
Ooooohhhh that's much easier. I ended up flashing a cm11 boot.IMG then installing SuperSU using that recovery.

edit: set up twrp dual recovery. much better now.
[Xperia Tablet Z Original Android Development] andyvdsteen:
New pollux-build is up. Works fine for me. :)

Not sure if it is necessary, but I did a system-wipe first.

first real work done after a one month hiatus in mexico and cuba - cigar smoke's lifted...

builds for both devices are now up. this is probably the last testing build before i will activate nightlies, so give them both a spin. they include all of sony's lollipop goodness, many device config updates, and some more kernel updates.
[Xperia Tablet Z Original Android Development] Azazel Azay:
New build for pollux

Screen can be locked in portrait mode finally :) and home button is finally working in other user accounts :)
[Xperia Tablet Z Original Android Development] swayamprakash2001:
Have been testing this since the day of its release and everything works as expected and the device is rock stable. As good as stock. Waiting for the nightlies to start now.
[Xperia Tablet Z Original Android Development] qsnc:
Surprise!

Flash junkies will get their fix soon. This thread remains the main forum of development for both devices, and I will keep monitoring it. Also, I might post UNOFFICIAL releases to test out stuff before folding it into the official releases.
[Xperia Tablet Z Original Android Development] jee'sgalaxy:
Didn't you release 12.1 unofficial before? The 12.1 5/27 has been my main ROM for my pollux_windy. It is the best AOSP based ROM I have used for this tablet. Netflix never lagged like it did in your cm12 releases.
[Xperia Tablet Z Original Android Development] silvestah:
+1

Also: It seems as of today your wait is over - a nightly for 07/04 is available via the roms update function or http://download.cyanogenmod.org/?device=pollux_windy / http://download.cyanogenmod.org/?device=pollux :)
[Xperia Tablet Z Original Android Development] zeus2602:
Tested.

Maybe 1 issue with Multiuser. [MENTION=759062]cm12[/MENTION]->i was able to config Names and Pictures for multiple users. [MENTION=759062]cm12[/MENTION].1->i am not able to access it: User not found, when i touch the profile.

Ok, i didn`t test the rom, most of the time..., i started to play kingdom rush.^^ ;) But hey, it`s running very smooth in this rom. :)

Good work.

When connect power cable boots automatically

After updating from cm12 to cm12.1 when I connect the power cable it starts automatically and also with the power cable is connected it doesn't power off but restarts again. The only way to powet off with the power cable connected is to press vol+ vol- and power button. Everything works fine with the power cable not connected.
[Xperia Tablet Z Original Android Development] qsnc:

edit: no nightly for 07/21, i've fixed the problem, so service will resume tomorrow.

is anybody having trouble with gps on plollux? when i start any gps app tablet just reboots :-?
[Xperia Tablet Z Original Android Development] MikeViller:
gps on windy pollux is not locking fast and when it does it's only on 1 satellite.... at cm12.1 startup is was really good even as a device only .......
[Xperia Tablet Z Original Android Development] xperiaatic:
attached logcat file, started "GPS Status & Toolbox" ttps://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2 and reboot ...

it seems to be related to lte-modem because reboots occur only when mobile-data/internet is active.

tested also cm11 and 10 and no such kind of problems so hardware should be ok.

as per my first post: we are talking plain CyanogenMod here, nothing else. and even within that topic, this thread is for device specific problems only. porting a camera app (or any app for that matter) is not and never will be within the scope of this thread, nor will it ever be my field of interest, sorry :)
[Xperia Tablet Z Original Android Development] xperiaatic:
GPS is fixed in cm-12.1-20150805-NIGHTLY-pollux.zip thanks a ton :good:

but also one question - is there any alternate/compatible recovery for this ROM that can make full ROM backup?
[Xperia Tablet Z Original Android Development] qsnc:
youre welcome!

there are plenty of ways to do that. the cyanogen recovery serves one purpose only though: to be a recovery :) you can still do "backups" with it if you know how to use adb and the linux shell (dd for example). i realize thats not very comfortable for the average user, and you might be better off using alternate recoveries/apps for that, but support for those is outside the scope of this thread, as its neither device specific nor a supported scenario within cm, sorry.

honestly, i have been developing for pollux for years now, and never had the need to do a backup of the data or system partition. if you stick with cm and dont brick it by some crazy experiment, you should be fine either way ;)
[Xperia Tablet Z Original Android Development] Rootk1t:
you can flash TWRP to FOTA partition.

[Xperia Tablet Z Original Android Development] qsnc:
as for the kernel - please don't post random questions because you think it will help. the kernel is properly maintained and updated, in many parts far beyond the original 3.4 series.

that is not an official changelog. check the log on your tablet for the proper changes. you can also nag the guys from cmxlog to fix up their device dependency tree... in any case, none of all that belongs here, i am afraid
[Xperia Tablet Z Original Android Development] astrovale:
I think I need some help! Since a few nightlies ago I didn't have this problem. Then I flashed what I think was the 23/08 one and suddenly I've lost Google store and continuously get the message that Google services crashed.

[Xperia Tablet Z Original Android Development] phillipssat:

How is battery drain and performance on this ROM? Huge difference from stock 5.1.1?
[Xperia Tablet Z Original Android Development] Rootk1t:
Not huge. Performance om CM is a bit faster according to Antutu benchmark (+/-25000), battery drain depends on build you are using, but it is not bad.
[Xperia Tablet Z Original Android Development] qsnc:
my pollux_windy is consistently above 26000 on antutu and comfortably beats sony's stock - but it will depend if you use f2fs, for example. however, benchmarks are not really representative for the user experience you get, and especially since all the cpu and io scheduling changes, cyanogenmod is so far the smoothest software i've seen on the fusion3 hardware. not ringing my own bell here ;)
