Here's my personal build of LineageOS 17.0 based on android 10. I don't want to make another thread since that's not required, i hope the developer doesn't mind this. If he does i'll remove it. I take no credits, all credits for device trees and everything go to [MENTION=5195210]gwolfu[/MENTION] and crdroid devs, i just fixed a few compile issues that's all. It uses Optimus Drunk kernel.

Everything should be pretty much working out of the box, i did test some stuff (cam/video/bt) didn't test it thoroughly so don't hold my word on this. when you open camera it will ask you for sdcard to be inserted but it works second time around. I suggest using DFE (non magisk) if you are decrypted, and use magisk canary 19.5 for root.

lineage-17.0-20191002-UNOFFICIAL-beryllium.zip

FOR GAPPS:

-Flash Rom/dfe/magisk

-boot

-flash opengapps beta

-boot, disable android setup app it will FC

-you can now sign in etc. It will work

why do lineage os updates not work anymore?

I tried to use the lineage os update setting (under system settings) and it does download the updates, but it does not install, when I click on install. It only starts TWRP but the install fails.

This happened to me for the last 20 released updates.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Largamelion:
Doesn't it say why it fails? I'm guessing you have to upgrade your firmware but it's hard to say if you don't give us more details.

I've run bbs for a while but I don't know what to change. My bad battery life doesn't come from poor standby, I think that has stayed pretty much the same as before updating. How do I tell what's draining my screen on time?

I want to switch to LOS. I'll be flashing the latest nightly and the DFE in OrangeFox recovery. I'm currently running 10.8.3.0 vendor and firmware from https://drive.google.com/drive/folders/1zGc3v1ahsN2dpkPppNAJJMDHKl8jnQmj.

Are these the best versions to be running?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] FordPrefect:
I do suggest to load firmware from here

https://xiaomifirmwareupdater.com/firmware/beryllium/

Not sure how reliable and trustworthy the Google drive link is.

The vendor part is included in the ROM as far as I know. So the latest nightly together with the newest firmware should be the best combination.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Lorog:

For me de LineageOs 17 build + Sphinx 3.1, is the best so far, no ghost touch (had them with previous LineageOs 16), perfect gboard keyboard (no lag), awesome battery, awesome performance, new gestures,....

I was a little afraid to upgrade....but since 2 days I realize is the best you can do :good::good:

Hello All,

I have tried to install LOS17 from this thread.

1. I wiped cache+system+data

2. Installed Firmware 10.3.7

3. Installed LOS 17

4. Installed Gapps

5. Installed DFE without magisk

6. Finally Magisk 19.5

now the phone boots to system and asking for password, after 10 secs it reboots into recovery. now TWRP also asking for password. not sure what I have done wrong here. Anyone can guide me?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
You were probably already encrypted and you didn't *format* data so it stayed encrypted.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] deathontheshore:
Yeah, I had that problem as well. Format data in TWRP and then installing LOS 17 solved this for me.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Astania:
Can you check if the 5Ghz hot-spot works?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Jeevan230497:
Thanks,

That resolved the encryption issue. but now the android setup is closing once the phone booted. I tried to disable the android setup app as suggested but disable option is greyed out. hence, it doesn't move to any other screen. anything should I do?

Edit: Flashing the latest gapps 20191006 resolved the issue. no more closing of android setup app. everything looks normal

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] digga50000:
Thanks for the rom. I installed the latest a few hours ago and must report that the touchscreen is still not fully fixed. However it's become better. Where the screen would be totally unresponsive to the point that I had to switch it off and on again (the screen) earlier, now it stays responsive. It still has glitches though. When I swipe up or down, there seems to be a horizontal line in the lower third of the screen which causes the notification bar to be pulled down. This almost never happens when I touch the screen very lightly, presumably using fewer touch-points, and always happens if I use more, pushing the whole thumb on the screen. Then it wildly fluctuates between the bar being pulled down and it dissapearing again. I will report again in a few hours or days, because in the past the problem only came after some hours or days. Btw the first time it occured I had already used the phone for months. Not sure if an update caused this, but the last time (and perhaps first time) I updated was the June 6. update.

I got an infinite boot animation after installing gapps in TWRP. So I wiped again (dalvik, cache, system, data), installed latest firmware then latest lineage os and now it boots again. But once I flash gapps it gets stuck again. So now I'm stuck without gapps.

What am I doing wrong? I selected the arm64, 9.0, nano so it SHOULD be the correct one.

edit: I think I accidentally flashed the android 10 firmware, now it boots with gapps.

The front cam on Poco F1 employs pixel binning, so the 20 MP sensor works effectively as a 5 MP sensor. Pixel binning is used to get much better low light pictures, without using larger sensors.

Hi.

I ran into some issues when trying to install LOS with Gapps. tldr: The freshly installed ROM is stuck at the boot logo for several minutes, after which it restarts to recovery.

It looks like the only ROM that boots on my Poco, is Lineage 16 without gapps. I have tried the latest (*091010) and older versions of Lineage 16 with several versions of opengapps (from the latest full to older nano versions).

As far as I know, I have flashed correctly, but maybe some of you can have some insight in it. I have TWRP 3.3.0.0 installed.

1. I format Data, 2. I advanced wipe everything. 3. When flashing, I tried to install via adb sideload, and also by adb push (after which I installed it from TWRP). The installs finish without any errors, and the phone boots into Lineage as intended. Unless I have any opengapps installed, in which case it just shows me the boot logo and eventually restarts into twrp.

Update: I managed to make it work. I installed the current MIUI ROM from Xiaomi, which apparently has a recovery included. After running the MIUI for the first time, I rebooted to recovery, and via "adb push" I reinstalled TWRP, LineageOS with MindtheGapps and Magisk.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
Do you have the latest firmware installed?

10.3.8.0.

Why not install everything via twrp rather than sideload?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] SergioTeddy:
There is a problem with latest LineageOs+OppenGapps instalation use MindtheGapps for now

Well, I've tried both ways. Since I wasn't exactly sure how each task is performed, I figured it can't hurt to try it both ways, maybe there is a difference to them.
