[DISCONTINUED][ROM][V2 08.12.2016] CyanogenMod 14.1 BETA (NMF26O) for SGP611/SGP621

[lowtraxx]

This ROM is discontinued. The successor of CyanogenMod is LineageOS which can be found in the corresponding Thread. The Downloads will be left here for the time being.

Disclaimer: Flash at your own risk! Backup your data before flashing! I am not responsible for bricked devices, World War III or your exploding cats!
Warning: The SGP611 images are not tested, but just built by me, as I do not own the device. But as the two devices are the same except for the 4G Modem, it should work. If not, please let me know.

About:
As my beloved SGP621 was just collecting dust, I decided to try porting Android 7.1 AOSP onto it. That worked well, so I moved on to CM 14.1
And voila, with a few tweaks here and there, it works (for the most part). But this is still considered BETA, so be warned and flash at your own risk.

What works:
- Display
- Sound
- WiFi
- 4G Data
- Bluetooth
- NFC (somewhat flakey)
- LED
- Magnetic Cover Sleep/Wake
- Double-Tap to wake

What doesn't work:
- FM Radio (It works, but only if Bluetooth is off and breaks if BT is on while Radio gets enabled)
- Camera (Taking Pictures works, but sometimes the camera is not able to connect. Taking a video crashes the mediaserver.)
- LiveDisplay is not working correctly
- Performance Profiles cannot be set (CM14.1 issue)
- You tell me

If your battery depletes rapidly, please disable NFC and check if it betters things. Then comment here, so I can look into it.

Flashing Recovery (This only applies if you do not have one already. If you do, go to the Flashing section below):
If you flash for the first time, you first need to download the CM recovery for your device from below.
To flash it, you need to put your tablet into fastboot mode (VolUp + plugging in USB-Cable) and then flash the recovery like this:

fastboot flash FOTAKernel recovery-scorpion.img

If you come from stock or from a ROM that does not support Recovery on the FOTAKernel partition, you also need to fastboot flash the boot image for your device before rebooting into recovery.

fastboot flash boot boot-scorpion.img

Flashing:
If you installed the recovery to the FOTAKernel partition then, while booting, get your device into recovery mode, by hitting VolUp multiple times once the LED flashes purple. Do so until it turns orange. (If you already have another recovery installed, boot into it.)
Now select install from adb sideload and from your computer issue:

adb sideload cm-14.1-(DATE)-UNOFFICIAL-scorpion(_windy).zip

gapps:
CM14.1 was tested with open gapps for Nougat 7.1 arm (nano confirmed working, others could be problematic)

Tips for better battery life:
I installed Naptime to trigger deep doze as soon as the tablet goes to sleep. I also enabled zzmoove cpu gov and noop scheduler in the kernel options. Because of the high display brightness. This leads to me getting standby battery consumption of around 1.2% per hour (measured with GSam Battery Monitor) which is nearly the same amount I got with stock.

damn, you're on fire hahaha. i'll be waiting for the SGP611 version.

Good work!!! Done it. Works fine until now. Will do more research in the morning. Anyway, there is an issue with Google Play. It says that my device isn't compatible with a lot of apps that I normally use. I flashed multiple variants of 7.1 Gapps. Which one did you use? What about build.prop? Or dpi? No idea. I will get back tomorrow with more feedback. Keep it up!

Please give an example of an app which does not work, so I can test and have a look in the logs. Below solution should fix those problems.

For anyone who wants to fix this without flashing the full fixed version. Please download attached file, enable root for adb and do the following:

adb push tablet_core_hardware.xml /sdcard/
adb shell
su
mount -o rw,remount /system
cp /sdcard/tablet_core_hardware.xml /system/etc/permissions/
chmod 644 /system/etc/tablet_core_hardware.xml
reboot

Your device should reboot then and all the capabilities should be available again.

SGP611 Version is up. Everyone who flashed the build for SGP621 please follow the instructions in my last post or flash the 1.0.1 version. Otherwise some apps from the playstore may not download/work.

Could you please try the fix described in the last post and report back if that eliminates your problems?

 

[Batyarap]

Thank you santa for the great surprise

 

[bogdaniux]

I have just flashed 1.0.1. The matter with Google Play is resolved. Kudos!

I had 3 crashes in 2h, while I was playing Clash of Clans. Always within a minute after waking the tablet from deep sleep. I tried to mimic the situation and get an adb logcat, but it doesn't crash while charging. Because it doesn't sleep. Do you think a logcat installed on the tablet could shed some light? Would that even remain logged after the crash?

There should be logcat apps in the playstore, that save the logs so you can review them afterwards. Could you also please try and disable NFC and see if that resolves the crashes? The only crashes I saw till now were all NFC related.

 

[bogdaniux]

The NFC setting is just blinking on and off continuously. I'll attach a logcat anyway. There are really a lot of NFC related errorshttp://cloud.tapatalk.com/s/5835b760cefb3/Log_2016-11-23_16-29-53.txt

You are amazing!

CM is working great only issue I've noticed so far is that live display isn't working but that's not a serious issue.

Keep up the awesome work:victory:

Update: Ignore this part I just found out its a problem in CM and not with this rom-Another minor bug, after disabling control ringtone volume in settings-buttons the volume keys still control the ringer volume when they should be controlling the media volume.

 

[nicke85]

OMG! I can't beleive that this rom exist for sgp611..Thank you, will try

This CM14.1's battery life is extremely good compared to AOSP.

I totally agree! Still, the tablet doesn't seem to sleep after charging. And, after disabling NFC, the tablet didn't crash anymore! Very happy about that!

At the moment I am looking into forwardporting an older version of the NFC lib, as it seems to have worked then. After that I will be examining the charging issue. To be clear, this happens if you USB charge while the device is on and once it reaches 100% the wakelock is kept? Do you use a Sony chagrger? Do you charge via USB or via Magnetick Dock/Connector?

It doesn't matter which charger I use, at least, apparently. I have a DK39 Sony dock, supplied by Aukey 3.0 Qualcomm fastcharger. All variants have the same result, even laptop USB charging. I didn't use my Sony charger in a while.

First of all, thank you for your efforts lowtraxx. I still love my Z3 tablet and the splitscreen function is a useful addition to the operating system.

It’s not really an issue with your rom itself, but with Android 7 in general. Google changed the way apps can request access to the external SD card. You could just edit a file in /etc/permission in the past, but that way doesn’t work anymore. I’ve only found a workaround using Xposed, which still hasn’t been ported to Android N.

Is there another way to achieve this? I’d like to keep the SD card as an external one, but I don’t think the ComicRack developer (my main usage for this tablet) will update the app anytime soon.

How may I contribute to get this rom running on top of the SGP-612 model (wifi 32gb)? By the way, many thanks for porting CM-14.1 to the Z3TC. This tablet is worth maintaining.

The only difference between the SGP-612 and SGP-611 is the storage so you could try flashing just system and boot without userdata (wipe internal storage and data in recovery first) or even flashing user data and then doing a factory reset if the wrong amount of available storage is shown (that works for nexus factory images) but I'm not sure if that will work.
