Confirmed works fine. However, first lock can sometimes take a bit long, everyon having this issue should first wait for 5mn to make sure GPS data is properly updated etc. before thinking it is a bug.

Can confirm it takes a bit (at least when I'm using geolocation without networking/offline). I use GPS Test or My Location to "see" when lock is acquired

I beleive that this process will resolve many issues posted here.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Steini86:
Did a clean flash. So far I like the Rom and have not experienced major issues. A disadvantage of this rom is that the user has to install the safety net fixed himself. In the last week I had it two times over night, that the display does not turn on the next morning, had to do a hard switch off/on. Maybe the next kernel helps.

In this rom I am missing the traffic indicator in the status bar. I know that LOS only supports showing that in the center where the camera is which makes it kind of useless, but for example the other LOS builds did manage somehow.

Overall, very nice built. Thanks much!

Just did a Geekbench test LOS vs crDroid, LOS wins (html5 multi-core in particular is way better in LOS for some reason).
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] v44r:
What's the purpose of ro.debuggable=1? I understand it is the default value for LOS, but with that enabled RootBeer detects the phone as rooted (https://github.com/scottyab/rootbeer/issues/147) and an important app I need uses RootBeer and fails to start if it detects root.

I've mounted system rw in twrp (finally found how to do it, simply mount /dev/block/mapper/system /mnt/system) and changed it to ro.debuggable=0 and now that app works fine, but I'm curious as to what the consequences of disabling ro.debuggable are (could not find any info on google).
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] paradøx:
I wonder if that's the reason why an app I use also detects the phone as rooted (and it's not). I use magisk only for that single app...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] v44r:
Maybe; RootBeer is used by quite a few apps. I watched adb logcat while launching the app that failed and it was clear that RootBeer was the cause, complaining about ro.debuggable=1. I suppose it should be fixed by RootBeer, but since the bug I posted is >1 year old I wouldn't hold my breath. Setting ro.debuggable=0 is faster :) (must be done after every reflash, though).

Can someone comment on using Android Auto with LOS? I used Arrow OS and had problems, switched to PE and AA worked very well. So before I switch I just want to make sure that AA works.

Thank you.

I don't use AA but our dev said it works as long as you use the recommended gapps (mindthegapps, created by LOS devs)

Don't mess with latest version, it's useless.

Just use the 1.1.1... any "newer" doesnt change the fix a bit. Support for A12 (which we don't care on LOS 18.1) and this riru stuff, even useless.

"Are we there yet???"

Donkey (c) 😁

Hi! First of all, thanks for that and for bringing (almost) official LOS to X3 NFC, all of us!

Not asking for ETA, but do you have a rough idea of when next update will be available? Within a few days or some weeks, for instance.

I'm (and probably others) just about to flash LOS for the first time on my brand new X3 and as next release will need a clean install I'd like to know if better to hold a bit on apps install or not, to avoid lots of apps data backup/restore.

I've read the whole thread and I saw you were on vacation recently....so welcome back and have your time. But if you can give us your feelings would be nice! Thanks again!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] 007_Fahad:
Asking for suggestion, what kernal is best for gaming in this rom?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
Look on the download server, under test folder, the 10/09 build called "signed" , flash that one... Already signed with release keys. Its my daily driver so perfectly stable.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] wilsonhlacerda:
Oww! Nice! 3AM down here and going to bed, but sure tomorrow I'll finally unlock bootloader and flash it. Thanks!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] treebaard:
Thanks for your work, Gardiol. :)

question: I'm currently on sawamen's build, but if I backup /data and format, can I just restore that backup and expect things to work? Or are there risks in that?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
As long as you format data....

I would not just backup data partition but use some backup tool like migrate or titanium.

Backing up the partition will for sure lead to issues down the road.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] sturges:
So if we install this one we can just dirty flash when the official build is released? or is it too early to say

I'm going to make this change later on and just want to make sure. 1st step open twrp and flash the miui rom (2.5 or so gb). Do I boot into the system and run the setup of miui, or just clear dalvik and then follow the developer's procedure on page 1?

Thanks for your patience.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] paradøx:
Flash the miui rom (it already includes firmware), but don't do any setup, just reboot to recovery, wipe Dalvik and Cache, then choose format Data (where you have to enter "yes"), reboot to recovery and do the rest (flash LOS, do the initial setup, then flash gapps, magisk...)

You can use mi flash tool.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] jjcdennis:
Thanks for the help. In this case would I flash the full rom (fastboot) version of the firmware - 4.6gb 06/02/2021 and not reboot to system? Then boot into recovery and follow page 1 instructions?

I'm not familiar with this process, so I appreciate the help.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] paradøx:
When you flash the full rom you are updating the firmware and fixing the partition (but you don't need the rom itself, since you're going to replace it with LOS anyway). After that you just have to boot to recovery, and follow gardiol's instructions (wipe, etc.)

There won't be an official 17.1, with Android 12 around the corner @gardiol decided not to waste his time with A10 and moved efforts to A11 / 18.1 (soon to be official, review process is going well.)

Didgeridoohan said here his module takes care of fingerprint and spoofing model props "but, TO FULLY FOOL the bootloader check you'll also need USNF, which from v2.1.0 also will take care of the model prop spoofing".

So I was just about to wipe this phone and rebuild with Lineage and I see the following screen. I click on the Install button and a box with the chinese characters and OK pops up. I have tried many times and nothing seems to happen. Should I install the drivers manually via the .inf, or does the box mean that I have installed them? Confusing.

if you click install then the driver will be installed automatically.

As I mentioned in my note, when I click on the install button the window with the chinese characters pops up after maybe 10 seconds. I'm not sure if the drivers were installed or not.

We had a setback and surya will not be scheduled for official build anytime soon, kernel still needs to be reworked, so be patient for a few more days/weeks.

Meanwhile, on the download servers, under the "test" folder please find the builds signed with release keys! Download the "release" zips, not the "test" zips in that folder, the latter are still signed with test keys, if you don't want to clean flash right now.

[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
I would not wait for official. Flash one of my test builds, but one of the "release" ones! So you can enjoy the release keys instead of the test keys.

Weird thing is I got three applications with problems. One of them is Home Assistant Companion App (allthough the problem is located in one of their javascript files, pushed from the server...). The other two applications I replaced with better ones...

But Home Assistant say to go to the Bromite developer, The Bromite developer says to go to the Application Developer OR the Rom developer. And now the rom developer says it is Lineage OS? If so, I will go there.

Hi @gardiol thanks a ton for that. It is always good to have in the pocket an alternative of a previous stable Android version for device, specially 10=>11 with some substantial changes for apps.

By the way, can you please write to us your (flashing/wiping) advice, main steps in the 3 scenarios bellow? I have my thoughts although I'm not very experienced with Xiaomi, but it is always good to listen to developer themselves just in case. This may also help other people if written/linked in OP.

1 - currently in stock MIUI Android 11 => going to LOS 17.1 Android 10

2 - currently in LOS 18.1 Android 11 => going to LOS 17.1 Android 10

3 - currently LOS 17.1 Android 10 => going to LOS 18.1 Android 11

Thanks!
