[ROM] CyanogenMod 12 (pollux/SGP321) - unofficial

[pandaball]

CyanogenMod 12 for Pollux/SGP321

This is built for the Xperia Tablet Z with mobile data. If you have a Xperia Tablet Z that has wifi only, please look at this thread.

No support, no warranty, nothing. This is a build I made for myself that I'm sharing to XDA. Development only questions. Normal Q&A go elsewhere. No ETAs. I will ask for any posts that ask about anything mentioned in this post to be deleted (eg. "why is recovery not working")

Working:
- Wifi
- Sound
- Screen brightness
- Touch
- Bluetooth
- Gyroscope
- Camera
- NFC
- Microphone
- Data
- Deep Sleep

Not working:
- Games seem to be slightly unstable and crash if too many things happen
- GPS. Use the high accuracy setting to find location.
- Flashing from sdcard in recovery

Update #1: Data is fixed in 20150113 version. I know the about screen still shows 20150111 as the version, but it's updated.

THIS IS NOT DAILY DRIVER QUALITY. EXPECT THINGS TO BE BROKEN.

Download: cm-12-20150113-UNOFFICIAL-pollux

Flashing the ROM from sdcard does not work. I tested adb sideload and it works. Reboot to recovery and select adb sideload when applying the update. On the computer, navigate to a folder with adb and run "adb sideload <path to zip>". The rest is automagic.
You will also need a gapps package.

Credit goes to FXP and the numerous code authors on review.cyanogenmod.org, whose commits I have cherry picked for this build.

Great work thanks

You note instability on games,,, is it terribly bad or fairly uncommon? Data, Gps and recovery either don't matter or can be worked around, but games are probably 30% of my tab use.

Thanks

Admittedly, I only tested on a very limited selection of games. It seems to crash on Angry Birds Transformers if you tap on too many coins at once, but it seems fine on other games. Noted instability anyway because I can't be sure if it's because of ART or GPU libraries, since this build does use the mako L preview adreno blobs. I also noticed slight frame rate drops on other games, but the games themselves did not crash. Admittedly I don't use my tablet that much for gaming, so I put gaming under not working out of an abundance of caution.

When we can expect that data is working? Tomorrow i try this rom...

Thanks, will give it a try soon anyway, as soon as I have some time to mess about with Roms.

There's always nandroids and titanium backup anyway

Now

Data has been fixed.

 

[mattman83]

Installed now on the new version (don't use data but why not have the latest) and games seem ok at a quick glance. As you same slightly lower framerate probably due to old blobs but no instability so far. Will keep an eye on things.

All else good so far, about 1.5hrs in.

I cannot install it

Hello, I've tried to install this rom via sideload and also via normal zip flashing and the result was an error message "Warning: No file_contextsThis package is for device: SPG321, pollux; this device is a yuga.
E: Error in /sdcard/0/cm-12-20150113-UNOFFICIAL-pollux.zip
(Status 7)
Installation aborted".
I cannot understand this, my tablet is an xperia tablet z with LTE not a yuga, I'm running CWM-based Recovery v6.0.3.5. How could I solve my problem?

Your ROM identifies itself as a yuga. Either flash a proper pollux ROM, change ro.product.device/ro.build.product to pollux in build.prop or remove the asserts in updater-script. You can also ask the maintainer of the ROM you use (nicely) to fix the build and change ro.product.device/ro.build.product to pollux.

PS. not recommended to mess with asserts in updater-script or change ro.product.device/ro.build.product unless you're 100% sure the tablet you're using is a SGP321. Messing with the asserts to make this flash on anything other than SGP321 may result in bad things happening.

Thank you, I've changed kernel and successfully installed the rom. The only thing that i've to signal you is that I still have problems with data!

Could you screenshot about tablet > status? Blank out things like IMEI as they're personally identifiable. Could you also toggle airplane mode on and off so that the modem is reset?

 

[Toxozoz]

I've tried to reset the modem, but nothig has changed. Tablet seems to recognize the SIM, but is not able to start the modem.
