Push the rom's zip to the SD card (optionally with gapps)
Wipe System, Data, Cache, Dalvik cache
Install the rom (+/- gapps)

From custom rom (CyanogenMod 13 or ResurrectionRemix-M):

Use flashtool with the lightened ftf below to update bootloader (only if you never updated to stock Android N. Be CAREFULL with flashtool, search correctly before use)
Flash the new TWRP (link below)

Tips

To use usb otg, just click on the “USB OTG” button in quick settings, this will enable the detection of usb devices for 30 seconds.
To boot into the new recovery you can press the vol- and power button at the same time with the tablet powered off. The touchscreen in recovery could make two or three seconds to works, don’t worry, it’s normal.


Thanks

Hello,

Thanks for releasing, I've flashed your new build and the WideVine DRM is working fine now. Good luck with getting the commits merged, hope this makes it to official status after your work to fix the last few broken items.

Anything left to fix at this stage? I see the camera is more or less fine, just a little perspective distortion in the camera app due to the preview window having the wrong dimensions which is very minor.

Thanks!

Read the lineage os blog post. Root is now an optional add-on so that users can use root-aware apps without installing root-cloaking software. Not difficult to install, just use arm64 from here: https://download.lineageos.org/extras

TWRP updated to 3.1.1-0

Can't install this package over newer build

TWRP updated to 3.1.1-0

lineage-14.1-20170517-UNOFFICIAL-karin.zip wont install with this recovery.

"Can't install this package over newer build" is the error message.

Can you upload a later dated rom or should I go back to the earlier TWRP?

This can be fixed by removing first line of the updater script.
Simply download the rom for your version, use you preferred zip tool to edit the file: META-INF/com/google/android/updater-script and remove the first line.

Thank you for the rom. At last it was released publlicaly. Everything works like a charm. Only mifare cards and stock lineage camera could be a little issue.

I've read where many users who have updated from Marshmallow to Nougat have experienced fast battery drain issues. Can anyone confirm this is not an issue with this ROM or that it has been resolved with 7.1.2?

No difference for me and I've been running nougat for a few months.

I should build a new version soon.
But in all cases you can also wipe ONLY the system partition before reinstalling the rom (I do it each time, even if not mandatory it's cleaner). You let your data partition unchanged so you will not loose anything.

Ok, so I'm ready to pull the trigger on this, but I have a few questions to be sure I do it correctly. I currently have a rooted Z4 with the custom AndroPlus kernel (it's on lollipop v6.x). So no custom rom, only custom kernel with root. So to follow this guide, I would use the flashtool with the lightened ftf, and flash the new TWRP and ROM, right? Or would it be better to just restore my tablet back to original factory state and then proceed from the beginning?

You need lightened ftp in case you have android 5/6 as twrp dosent work with old bootloader. If you have any version of noogat stock. No need of ftp. Also, it might be flashed trough androplus recovery.

 

[Jadog]

Perfect, thank you. Also, right now on AndroPlus I have the DRM Fix that emulates the DRM keys to allow for Sony's Image Enhancement. Will I loose that with this ROM?

Lineage dosent need any drm fix. It's only stock feature.

 

[myhrdak]

the rom i was waiting for. much better battery, especially in standby. i use the tablet only on special days
and till this day it loses 3% per day (using leandroid for flightmode while display is off).
with stock nougat i lost 10% per day.

Well that's even better! Seems like the perfect solution. And from what I understand I can get full root by installing SuperSU from here using the ARM64 version and installing via TWRP?

Am I required to have an OTG cable and attach a mouse to make any of this work? Or can it be done without? Thanks for the excellent support!
