Hello !

​

LineageOS is a free, community built, aftermarket firmware distribution of Android 10 (Q), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Reporting Bugs

• DO NOT Report bugs if you're running a custom kernel or you installed Xposed
• Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
• If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
• If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

Ok, the OP was updated right now with the links for download a very early test ... of course it's not be intended to be used, only for test and fun for the moment !

Thank you for your attention !

OK, installed with OpenGapps Micro; on boot, getting error 'Android System' 'There's an internal problem with your device. Contact your manufacturer for details.' This shows up over the 'Hi there' screen. I will try to continue the installation..

EDIT: It is not able to see wifi networks. I will skip and see what happens.
EDIT: Able to setup PIN; no option for fingerprint on setup.
EDIT: Booted Lineage, but still not able to see any wifi; at this point, I will stop testing.

Yes, I have the same issue after boot ... I guess it'll be fixed in the next update, it's nothing serious ... Just a Warning !

Also you can consult What's Working list from OP !

Anyway, thank you very much for confirmation that it's booted successfuly on BTV-W09 !

Thanks !

Actually you can install it only for fan or to explore what Android 10 come with ... as for moment almost all functions are still not enabled !

This is a big surprise for me. Never expect to see a custom ROM for this device. Time to try to unlock the bootloader. Lineage 17.1 is a great ROM. Thanks!

Project Status : WIP. So I guess we will not be able to get the camera working?

Yeah I know I read the short not working list haha.. And I can see that some didn't. Maybe make it bolder and bigger. XD

I used reverse tethering to get some kind of internet conenction. Installed some apps and I'm having fun. it's usable. Posting this comment from it now.

Chrome got some freezes. But the stock browser is working fine. For me if it's not soft rebooting every couple of seconds then it's usable. Job well done.

 

[Me,You,and Daigorou]

Amazing, because we can take modernity on our device thanks to you. I stay still EMUI, however I am glad that you give us great possibilities.

Thank you very much surdu_petru.

Hi !

Bluetooth & Audio fixed right now on Android 10 LOS 17.1 ... unfortunately, audio it works exactly like on Android 9 with the same issues .

 

[friedsonjm]

For root, https://download.lineageos.org/extras only goes through 16.0 Wouldn't this ROM require 17 ?

Link says 17.1.1 lineage-17.1.1-btv.zip but download file name is lineage-17.1.0-btv.zip ?

 

[surdu_petru]

Ok, sorry ... fixed !

 

[friedsonjm]

Booted... so far, same 'there is an internal problem with your device' error message immediately upon boot...
Still no connection to wifi, will restore back to 15.1 and wait for next version.
Thank you for continuing to develop this!

Do you flashed the same build of LOS 17.1 and do you expect it to go better than the first time ?

No, I booted the 2nd build, to see if there were any changes. Unless I'm confused and there was actually only one build?

I'm sorry once again that I wasn't explicit enough ... Usually I stated clearly New Update when a new release is out !
I'm working to fix WiFi before to release the second test and I hope to release the new update as soon as possible !
