Can I use the old vendor_boot.img file from this version https://lineage-21.0-20240605-nightly-alioth-signed.zip ?

As the latest version doesn't have this file it won't be a problem? Or is it better to wait for the next version, which will already contain this file. I want to do an update from version 20 to version 21.Currently I have https://lineage-20.0-20240501-nightly-alioth-signed.zip/

Follow wiki.

Update firmware then flash rom, gapps (if using) and magisk (if using).

I also made the step now! I'm dirty flashing my F3 continuously since late 2021 now, and it just keeps running :)

I decided to take the image from 5th of June to avoid any problems, in correlation with the (maybe) missing vendor_boot in the current build. Will OTA to the next build thats probably coming out the next days. Everything was running smooth except LSPosed needed to get switched to LSPosed_mod, since the official version is not maintained anymore and was crashing my Zygisk.

I tried to update from LineageOS 20 to 21 today, but it went wrong somewhere.

I tried to install lineage-21.0-20240619-nightly-alioth-signed.zip. Before, I updated my firmware as instructed.

After installing LineageOS, I tried to install MindTheGApps, but that failed with the error "could not mount /mnt/system". So I tried to just reboot, but it just booted into fastboot.

At this point I can't re-flash LineageOS 21; it just fails with errors like "error applying update: 63 (errorcode:kpostinstallmounterror)".

For now I re-flashed LinaegeOS 20, and that seems to be working, fortunately, although the GApps seem to be ****ed ("Google Play Services keeps stopping")

But how do I proceed to here to update to LineageOS 21? What did I do wrong?

Does flashing my unlocked international device running LOS 20 with the EEA ROM before updating to LOS 21 work or could it cause a bricked phone?

Congratulations! You can be assured the phone you have purchased is the official international version.

I flashed the EEA firmware (OS1.0.1.0.TKHEUXM), since I'm in the EU and I thought that is the version my phone is.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Lineeege:
Try the global version. My understanding is: international = gloabal. Maybe this does fix your problem. If that doesn't work, just leave MindTheGApps out of your system and wait for a future release fix.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Compizfox:
I looked it up and I definitely flashed the EU version on this phone before.

The problem isn't just MindTheGApps, I couldn't boot into Android at all after flashing LOS21.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] R!ffRaff:
Follow the instructions.

Did you have the correct firmware installed on the phone? Install the firmware stored in the instructions. I have been using 2 F3 with Lineage since I bought the phone. You can also install Gapps afterwards. Nikgapps offers different packages as Opengapps did back then.

Guys,

Don't make the same mistake I made by flashing the newest global firmware (1.0.3.). The phone wasn't able to boot up, so I tried to flash the previous firmware version from Recovery as I had done in the past when experiencing troubles with a newer version than what the maintainer recommended.

Except, this time, it was impossible to access Recovery...

So I tried to solve it by reflashing boot.img and vendor-boot.img, but I didn't get the Recovery back.

Long story short, I had to reflash every firmware partition from fastboot with all .img files from the previous firmware.

Hey guys,

just a heads up to everybody using workprofile:

I set up a workprofile with island long time ago. Now after migrating to Android 14 I casually unpaused the profile like I've done 100s of times before, but this time I hit an bug that turned my Android into an unrecoverable state. All Apps (Private + Work) would get denied all permissions (even wakelock, internet etc.) from the system (even tho granted in settings and everything) and therefore no apps with exception of the google and system ones would start anymore. I couldn't find anything related to this bug anywhere. Luckily I still got full access to the elsewise working phone and could do backups of everything via ADB, before I tried to flash the previous night build (just for the sake of trying) and got the device in a boot loop (now I also know it is not possible to return to an earlier build).

However, now I have a fresh Android install again, which is not the worst thing after dirty flashing for years! Tbh at some point I expected problem like this.

I have the issue now that the suggested replies for messages like "Thanks!", "I'm good" etc. are not showing up anymore. In the notification settings "Enhanced notifications" are enabled, but it wouldn't do anything. Does anyone know what else I do need to activate?

[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Luciano461:
Hi all. Just bought Poco f3 as a replacement for my beloved mi9t ( unfortunately the screen got completely smashed) . Mi9t on lineageos 20 was literally a perfect experience for me, no issues whatsoever and i love plain android experience. Poco f3 on lineageos 21 is giving me issues. Afaik ive installed everything correctly. New phone>updated to hyper os>unlocked bootloader>flashed everything like it says on the lineage website. Im running 2 sims, the first issue was unknown caller id, solved that by disabling VoLTE. Then Ive encountered an issue with my bluetooth earbuds ( jbl live pro + tws btw ). Everytime someone would ring me while im using buds I would get one signal and whoever is calling would get disconnected ( strainght to voicemail ). Ive solved that by disabling phone calls on my buds in bluetooth settings. I know its early days for lineageos 21 on poco f3 and ill wait for updates patiently. Anyone experienced similar issues? Is it bugs in the rom or perhaps I have done something wrong during the installation?

@althafvly Can we get Wireguard support? I see on Gerrit that there's a bunch of other Lineage devices where the maintainer has added support.

The userspace implementation of Wireguard has almost double the battery drain, and less performance according to Wireguard's tests when comparing to a kernel level implementation.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] althafvly:
It's already there in alioth. To use it, you need to root your device. Wireguard app requires root to work.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] duttyend:
Thanks a lot for your quick answer!

Yes, I'm using the latest update. It was working perfectly with the previous nightly build.

Is there some config file that could be deleted to 'reset' it?

Edit: it's working fine again after a reboot.

Thanks again @althafvly
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] :
Hey @althafvly appreciate your work on maintaining this device as always. One question though, is the reduction of status bar padding on the left side recently an intentional change? I prefer how it was prior.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] R!ffRaff:

[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] R!ffRaff:
which firmware or update do you mean exactly? for LOS you should use the firmware that the dev has specified. I have no problems neither with the firmware nor with the OTA update. LOS21 on the Poco f3 runs really smooth :cool:
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] sojok15610:
We installed latest and greatest firmware as any chad would do. But yes we don't have any problems with OTA or recommended firmware.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] R!ffRaff:
There is a good reason why a certain firmware should be used. In the case of a new firmware, lineages may also have to be adapted under certain circumstances. I don't see this as a mistake now. A new firmware does not make everything better either. Best example of OEM unlocking in HyperX OS. If you install a different firmware, you also have to reckon with the consequences. Your problem does not belong in this thread.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] sojok15610:
It was not a rom problem but a firmware so I think it belongs here. You can cry about it if you want.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] R!ffRaff:
what is your problem? @althafvly will already make a change if it is necessary and adjust it. I see no reason for this discussion just because you want to install the latest firmware. You can read about the requirements for the ROM in the instructions. What's your problem? Are you a liitle girl or a baby?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] samantas5855:
The dude's phone got bricked and you are attacking them? Flashing the latest firmware is something a lot of people do as it can help with signal issues as a last resort. The latest EEA (I don't know about the other regions, didn't try) is broken and creates issues. It hard bricked my device. This issue should be raised before other people's phones die too.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] R!ffRaff:
The instruction works. You have to extract the firmware and flash it. I have several F3 in the family and no problems. Why you just take a different firmware contrary to the instructions, I can not understand. It looks like you made another mistake. Also a change of the firmware from EEA to Global etc. is without problems. At that time, the China version always received the latest updates. This also works in Europe, only some tapes are not available (hardware). I've been doing this for quite some time and come from Cyanogenmod and for years at LineageOS on different devices from Xiaomi, Moto and Samsung.

If you have a problem, you should first install LineageOS according to the instructions. However, I would leave a different firmware and if so, then only if the DEV releases it. The other problems will be fixed or eliminated. There is no right to a specific firmware and the use is at your own risk.

I'm not sure if you are new to LOS, but nothing of what @R!ffRaff said is really wrong. I would guess that more than 90% of issues people have are down to not using the recommended firmware.

In saying all that, people are free to try another firmware for whatever reason they like. Some people have issues they want to fix and others just want the latest available everything. People like to tinker.

They shouldn't be stopped from asking for help on the forum, but they should be prepared for a few salty posts and zero help from the dev :)

Hi all, I have a Poco F3 128GB for daily work on LOS 21. Works great, and after following https://wiki.lineageos.org/devices/alioth/fw_update/variant1/ it worked even better, Fingerprint Reader etc.

Now I have a second Poco F3, and I would like to clone it from the first one.

The first F3 hat no Google, no Magisk but various aps and 4 users installed.

There is no TWRP installed, rather the LOS Recovery V21.

The second F3 still has MIUI installed, just getting the bootloader opened.

Any best practice?

Hi.

Anyone have a working screen breathing for notifications?

or similiar mater always on display?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] noraj1137:
I bought a POCO F3 with STOCK EU ROM and made all the updates (13.0.4).

Then I successfully rooted it using magisk.

I played around a bit with MIUI (first time I'm not on stock AOSP) and I didn't like all the adsware and stuff so I tried to debloat it using Universal Android Debloater. But even done with debloating I was not satisfied with MIUI.

So I decided I did all this for nothing and decided to flash LineageOS.

Then I successfully flashed LineageOS 19.1 + GApps.

My question is : now how can I root LineageOS using magisk?

All previous Lineage rooting guides are obsolete because they used the ZIP flash version from TWRP or stuff like that but no more Magisk zip is provided for v24.3, the only supported way is patching boot.img and flashing it via adb (what I did for rooting MIUI at first).

But now that I'm on LineageOS what does it change? Should I extract boot.img from lineage-19.1-20220528-nightly-alioth-signed.zip and using payload dumper again and do exactly the same thing as for the stock ROM? Or is there so special precautions to take to keep GApps working, or avoid messing with A/B partition system etc.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] noraj1137:
If you are on stock MIUI just apply all update from OTA in system settings when you are on the last MIUI 13.0.x.x update then flash LineageOS last version. No need for third-party xiaomifirmwareupdater. Yes it will first offer you to update to 12.5.8.0 then to another update and so on until 13.0.x.x, you can't jump over directly to 13.0x.x.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Doomkopf:
You can actually still flash magisk using a recovery. You take the Magisk-v24.3.apk file from github, just rename that to Magisk-v24.3.zip and flash it :D If you want to read more on it, click on "installation instructions" on magisk's github page (under "useful links"). On the bottom of the page, it tells you how to install magisk using custom recoveries (basically I just repeated whats written there)
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Doomkopf:
You dont need to be on the lastest MIUI to flash LineageOS. you just need to have the latest firmware installed before booting LineageOS ^^ You can have that by just flashing the firmware part, not whole MIUI
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] fikrillah:
thank you for your anwaer. so, a file from this link is suffice?

even though i already installed lineage, i just want to be sure for future reference, is it ok to flash android 12 firmware form stock android 11?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] fikrillah:
Hi, it's me again.

I had a defective touch sensor by factory, and i the defect is less noticable on MIUI 13, on MIUI 12 (I only ever used the earlier version) the defect is more noticable, as much as on recent version of lineage. I'm just asking if the devs know or can do something about this.

A bit off topic, but is it normal to have an inaccurate touch on this device? Has anyone experienced the same? At least I don't have this problem in my older device. It ticks me off

In the meantime, I'll try to claim my warranty, hope it'll be a accepted as I don't see any explicit mention of software modification in their tos
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Doomkopf:
Yes, exactly. But I recommend checking out the telegram channel of LOS alioth, and using the command "#firmware". It tells you what version to use in your region

I don't know what you mean by the second paragraph. When using Android 11, you should not use Android 12 firmware. But if you plan on flasing an Android 12 rom, you flash Android 12 firmware, regardless what you had installed before :)
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Doomkopf:
I sometimes have this problem too, but I use a screen protector. Do you use one? Could be the issue. Also, I noticed it getting worse when it's hot.
