[ROM][OFFICIAL] LineageOS 14.1 for Nexus 9 (flounder)

[tibere86]

Anyone figure out build.prop edits that will allow the Nexus 9 to play 1440p YouTube videos again? My maximum resolution option is 1080p. Ivebtried Vanced YouTube, but that didn't work.

Hi,
I have created a new profile for my better half a couple days back. Strangely enough, when I go to google play store with her profile, it says device is not play protect certified (or rather does not say anything about certification) whereas the device is certified when I check under my profile. The google play store version is the same on both profiles, 16.6.26-all. No certification means that I had to download an ancient version of netflix app for example.
Any ideas how the same tablet can be both certified and not at the same time and how to resolve this Schrödinger's tablet situation? Thanks!

Schrödinger's tablet... LoL
Are you using magisk? You may have to enable it for other users. In magisk settings for your main account. Not completely sure, I haven't used a 2nd account on mine in a long time.

I'm not using magisk as far as I know. Play Protect has worked for the first account without needing any extra actions.

@razorloves Thanks, for the work! I've tried to install the custom rom from latest original rom. Unlocked bootloader, installed twrp, installed latest posted linage (from here) and installed gapps nano 7.1/arm64. However, I don't get over lineage boot logo, even after ~45min. I know first boot takes time but this seems too long. Any advice how to debug, or did I forget to flash something? Thanks in advance!

Edit: Flashed everything once again...works flawlessly. Anyways, thanks for the efforts!

@razorloves thanks for keeping these builds alive. The N9 is showing its age however is still good to browse around

New builds available with September security patches :good:

IMPORTANT NOTE: I disabled forceencrypt. So this rom will no longer automatically encrypt the data partition if it's not encrypted.

Hey, awesome! I have always wanted to try my tablet without forceencrypt. I would have to do a complete wipe and fresh install for it to be not encrypted anymore though, right?

no. just format data.
if you want to switch without losing anything, do a twrp backup with just data selected. then copy all your stuff in /sdcard to a pc. format data. copy everything back to tablet. then in twrp restore the data backup you made.

Thanks, works perfectly! The tablet feels significantly more responsive without forceencrypt.

Is it possible to make this build to pass RootBeer (github) checks? Some streaming services have started to use RootBeer to check for root access and they won't start.
Triggers:
- /usr/bin/su
- build.prop: test-keys strings
- build.prop: userdeubg strings
This is probably too much to ask, but I mainly use this tablet to media and reading so maybe others might have seen this issue as well. Anyway consider it, I know some people will use su so probably this idea isn't best suited for everyone but just throwing it out there.

Unencrypted nexus booting up as writing this. Thanks for the update and keeping this device alive!

- if you want to get rid of su, just flash the su addon remover in first post.
- i would have to sign the rom with private keys to remove the test-key strings, and i'm not doing that.
- all lineage builds (including official) are userdebug, so userdebug strings are not going to be removed or changed.

so, just use magisk, like what was suggested to you a few months ago when you asked this question.

or, just fix it yourself by opening the build.prop file with a text-editor and changing the test-keys and userdebug strings.

Thank you for your builds, razorloves!

I just updated my Nexus 9 from one of the final official LineageOS builds with December 2018 security patch to your new build with September 2019 security patch without any issues!

Holy bazingas, Batman! A ROM with 2019 security updates on this long forgotten (by Google) Nexus?!

It must be christmas!

It's not everything updated. The vendor partition is still that by Google in 2017.

I just bought an N9 for my son and decided to build my own from cm-14.1 source for security updates, only issue I am getting is vendor image mismatch (I'm running LTE).

Then I stumbled upon this. Are you still using the vendor img from post #2 (I flashed to test since stock is still complaining)? Does your ROM have the same issue too?

 

[mrk2815]

If all the parts of the rom are updated what is the difference between all that and the vendor partition from 2017. i dont get . can

yes.
no.
sounds like you did something wrong with your build.
you can get help with building on our irc channel, like mentioned on the wiki rom building page.
