2018-10-02: It is my pleasure to announce, together with @Quallenauge and @matshias, the availability of unofficial LineageOS 16 builds for the Lenovo Yoga Tab 3 Plus devices (YTX703F and YTX703L).

2019-03-12: And now official lineage-16.0 builds as well!

Issues
  • Audio over Wi-Fi Display is transmitted at the speed of sound, instead of speed of light :)
  • Flashing over anything else (official Lineage 15.1 etc) is not supported - data wipe is required. Working on 2 migration packages: unofficial <-> official and 15.1 <-> 16.0
  • Double tap to wake (dt2w) does not work too well over long term and I don't recommend enabling it - only added to build per user request

Official Instructions


Migrating from Unofficial 16.0 to Official 16.0

  • Boot to TWRP
  • Install Lineage OTA zip
  • Install the provided migration-to-official.zip
  • Reboot from TWRP to system

Migrating from Official 15.1 to Official 16.0

  • Boot to TWRP
  • Wipe system partition. This step is critical. User data is not lost when system partition is erased.
  • Install Lineage OTA zip
  • If you had OpenGapps in 15.1, then you must install new OpenGapps for ARM64 for Android 9.0. If you didn't have OpenGapps in 15.1, you must not install any Gapps package.
  • Reboot from TWRP to system

Migrating from Official 16.0 to Unofficial 16.0

  • Boot to TWRP
  • Rename the provided migration-to-official.zip to migration-to-unofficial.zip
  • Install Lineage OTA zip
  • Install the renamed migration-to-unofficial.zip
  • Reboot from TWRP to system

Downloads


Changelog

  • 2019-02-04: fixed camera and sensors not working while data partition is encrypted and startup pin is required
  • 2019-01-27: added built-in support for root, fixed Wi-Fi Display (WFD) video (but not audio yet), fixed USB MTP mode, updated GPS HAL and blobs from bq bardock, updated Netmgr QMI DPM (Data Port Mapper) blobs from xiaomi daisy, fixed SELinux labeling for userstore partition which should solve Wi-Fi MAC issues for all YTX703F users, restarting qmuxd when userdata is encrypted, which should fix LTE for YTX703L users with data encryption
  • 2018-12-09: fixed alarms not firing, wifi tethering crashing, temporarily added back support for software dt2w

I know right? Maybe by the time the Lineage 16 bringup is over we can do something about it.

Can it be that the display is quite dark, even with 80% brightness, seems similar to the 15.1 update 2 weeks ago, where something with brigtness was no good.

I know, it´s a beta version now, but brightness should be a must to test the next 2 months....until official, thanks.

Is your issue that the display is dark despite being at max setting (a hardware issue), or rather that the automatic brightness control won't stay at max setting (a framework issue)?

sorry, but i did not understand very well your comments.

i wanted only to say, that comparing with my last installation 15.1 with 45% brightness, now with LOS 16 seems to me, that 45% brightness is much more darker than before, so i put it on 80% now to have the same. But sure battery will spend more ....

In the meanwhile i could install opengapps 9 nano, magisk 17.1 all with not any problems, i like it very much the new build, thanks a lot... will use it and test it...

concerning dolby atmos: with 15.1 i had successfully installed the dolby-atmos-axon7-oreo installed---do you think i can flash ist also now with the new build?

I mean: if you disable automatic brightness control, is the screen any brighter?
no, it´s the same.

for me is a similar issue as we had short time ago with 15.1 official rom, when @Quallenauge wrote this:

Thanks, there were some changes in the background made which changes the way how the brightness is controlled to achieve the battery save mode. Maybe there is some tuning needed (if possible).

Other issue: i tried to flash dolby atmos, but got boot loop, so i had to wipe once more all and flash the new build once more.

but could reinstall all my apps with my google account, installing opengapps nano 9 - great thing.

thanks for all

It is my pleasure to announce, together with @Quallenauge, the availability of early access release LineageOS 16 builds for the Lenovo Yoga Tab 3 Plus devices (YTX703F and YTX703L).
To the best of our knowledge, the hardware works and SELinux is in enforcing mode. However, as Lineage 16 bringup is not complete yet, many operating system customizations are not yet available and there might be various minor glitches in the SystemUI.
These builds are of BETA quality and are not intended for stable, daily use yet. Installation is "as usual" - non-specific instructions given intentionally to deter people that are expecting stable software from installing and then complaining about things that are irrelevant at this point.
The purpose of these early builds is to speed up development by figuring out the next top priorities. Today also marks the movement of Lineage 15.1 into maintenance, no-new-features mode, as we are now investing our efforts so that most of you can hop on 16 in the near future.

What works

Connectivity: WLAN, Bluetooth, LTE, GPS

What doesn't work or wasn't tested

Can't wait for it to become stable enough for me to use this. Sadly I can no longer spend much time testing and trying things out.
But you guys are doing great work. It's hard to believe such a unknown device is getting so much development and such a great little community and devs.

Cheers

At this moment I have only 2 main issues:

Display missing brightness (too dark)

Sound could be louder, don't want to go to 100 % volume

I don't know what you're seeing/hearing, but I'm telling you for sure that the backlight brightness fix from 15.1 was integrated in these buils. Also we changed nothing about audio.

Look, what I reported is my impression, no critics and only comparation to 15.1 build, nothing more.

I only want to help, right.

to be sure about my display i restored my Oreo 15.1 backup and then restored again my Pie 16 backup and i confirm that with Pie 16 i have to configure about 80% display rate to have the same clear display as with 40% on Oreo 15.1

I don´t know why, i have automatic display disabled in the 2 builds, so we have the same conditions.

Concerning sound: ok, the comparation was not correct, because in Oreo 15.1 i could use the dolby atmos tool which i had installed.

I will continue with Pie 16 because it is the future and i like it, principally closing open apps works so fine swiping up...

And sure, i hope the display setttings will improve and one day i can get my dolby atmos also installed in pie...:good:

Is there any chance for DT2W in this new Pie build?
These unofficial builds are only meant to exist until the Lineage 16 bringup is over and officials start shipping.
There is a 5% chance that my initial estimation is wrong and the touch panel really supports wake gestures at the firmware level. Now that I got a hold of a Synaptics datasheet, I can take some time and read the relevant registers to figure out whether that is the case or not. If it does, I'm glad to add it back. But if it doesn't, I hope it's understandable that I don't want to waste my time again by putting in and testing a temporary feature.
But by any means, do feel free to do that yourself if you want to, the community is not a single person or 2. Patches are here:
