[ROM][UNOFFICIAL][6.0.1][SGP712/SGP771] CyanogenMod 13 for Xperia Z4 Tablet [Alpha]

[andralex8]

Thanks guys! I'm up and running with CM13 now and I'm very satisfied with it!
I can feel it's an Alpha build though, not in any way bad as it's so far a very stable build it seems, but smaller things that need tweaking;
Wi-Fi seems unstable, and I can't use the tethering options or get them to work.
My biggest problem is OTG.. I haven't tried everything i need OTG for yet, but registering a USB stick is broken it seems. The USB drive reacts and shows a little LED light, but the tablet isn't registering it and I can't find the option to detect USB (like you could on stock ROM).
If anyone knows of a fix for the OTG, I would be happy.
Other than that I tip my hat to you dev! Very good work so far

Edit: I noticed after i flashed the ROM that my computer won't detect the tablet in fastboot mode anymore. Is this a common issue?

Thanks for the feedback!
OTG should work. There is no option to enable it like on stock because it's enabled by default. But maybe the tablet don't mount the key? Wich app do you use to browse the files? For me, simply insert an USB key works, I use ES explorer to browse the files.

I'm unable to download Google Play Movies since installing cm13 on my z4. Any fix for this?

I don't use Google Play Movies. I seem that other people already had the same problem on other devices, but I only made a quick search on google, so maybe someone already find a solution ? Did you find a solution ?

395.6MB Sep 18, 2016 | 07:58PM) but tablet do not have sound. What am I doing wrong
Thx

It seem that you made things correctly. Maybe you can try to wipe data (make a backup if you have datas to save). Or did you change any settings ?

Hi guys, having trouble connecting to and pairing the bk50 keyboard. Not getting a pin prompt and not seeing a successful connection created after several attempts. Lots of Bluetooth share error messages... Any tips to resolve? Was working fine for a month previously so unsure what changed, maybe a Bluetooth beacon spammed the service??

Update- yes it appears that bluetooth beacons can cause the bluetooth service to crash so much that keyboard pairing fails all the time. Moving physically away fixed it so not related to the rom, just another issue caused by Android's limited list of entries for known bluetooth mac addresses (the beacons are 'illegal' bluetooth devices which dynamically change mac to ensure they are always discovered as a new device, which fills the table and crashes the service once table is max size).

Thank you for the feedback and also for sharing the solution you find .

Thanks for your reply. I went back to stock. I can't live without Google play movies. Battery life has drastically improved as well.

Its mostly working but would it be possible to get regular (if not necessarily frequent) builds to cover the monthly Android security updates?

Yes, you're right, that what I initialy wanted to do but I forgot to do it for October. The November security update is not already released, so I will wait next week-end to make a new build to have this new mounthly update (I hope it will be release at the begining of the next week, then there is a small delay before included in cm source, so next week-end should be good).
Sorry for the increasing delay between builds, I was very busy (and I will also be very busy for at least till the end of the end of the year).

For other updates, I don't have the time currently to make a deep debug make a more working 1.3.3 kernel. So I let the 1.2.2 kernel for the moment.
Android N for Z4 tablet should be released by Sony by the end of the year, so the new kernel sources will be available and it should be easier to debug this 1.3.3 kernel by comparing the sources with the stock kernel (that what I did for OTG on 1.2.2 for exemple).

I use the app called File Commander. Other OTG functions work, like using a Dualshock 4, mouse or keyboard, weirdly enough..

you should try a newer version of the AndroPlusKernel. IIRR V38 is the minimum for 6.0.1 and V40 is working like a charm here (with original 6.0.1 from Sony for now)
I'll switch to cy13 later this month.

If other functions works, the usb key should works. Maybe the tablet don't mount the key? Did you try with an other browser ? Or in comand line?

I tried with the build-in CM file manager, but it does the same thing. I noticed as well that the android system doesn't show the USB key under the storage menu in settings.
Now you mention command line.. How would i do that? I have never fiddled much with the android terminal, if that's what you're referring to

Edit: is there a changelog for the recent update?

Update feels really good but speaker volume is still below average.

Try lsusb with and without the usb key plugged to see if the tablet detect the key. Did you try with es explorer too? The key is not shown for me nether in the storage settings, but I can access it, and it's not shown neither with the mount command, strange...

Only security update (update cm source code)

 

[andralex8]

New update !
Same modifications as RR :
- Increase max speaker volume
- Set the minimum brightness lower

Hey thank you very much for this mod.

I installed it to my tablet after the latest update to play around:
- Firmware: 32.2.A.5.11
- Androplus kernel v42 (I installed it with your TWRP)
- xposed-v87-sdk23-arm64.zip

I have seen so far two main issues:
- The MAC address is different every time the tablet is booted. This is a problem for the people like me, who filter MAC addresses on the WLAN router.
- The tablet is making a funny short noise more or less every minute, sometimes more often, like a *clack* on the speakers, similar to the default noise when pressing a keyboard key.

Any chance of a lineage port for 7.1.1?

Yes, more than that.
I will not tell too much, but I can already tell you that it will be better than the marshmallow roms .
We are working with other developpers wich are doing an incredible work for the Z4/Z5 platform that can be used for the Z4 tablet too.
The rom will be released when fully working (at least beta, no alpha version this time).

That's also the reason why I will not update the marshmallow roms in the futur, the next update should be nougat .
