[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Optimissimus99:
I have a question:

today I flashed build 20210313 (before I had an older build installed, probably late frebruary). For years, this was the first build that failed booting for me (Bootloop).

I didnt think of anything special and dirty flashed (downgraded) to the version before (0306).

After rebooting, lineage, but also TWRP do now ask to decrypt data. Even with my correct pin, it fails to do so.

(I think because the security patch level is now upgraded)

I think I had a very similar issue years before, back then updating to a newer rom fixed it up again.

However this was when Lineage was still decrypting on boot normally. It doesnt do that now anymore (not when it is working normally at least)

Is this correct? will version 20210320 (which hopefully will be built tomorrow) fix this issue?

Or can it be fixed otherwise? I dont necesarilly need the /data partition or a booting system, however I do need the /sdcard partition, as there are a lot of important files on it and my backups are kind of outdated.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Optimissimus99:
20210320 is out, but it didn't fix the error. So I suppose the internal storage encryption has nuked the files.

(default_password and the 4 digit login pin don't work)

Just so others don't make my mistake anymore:

- With Android 10, NEVER EVER do a downgrade to a previous security patch level or especially vendor.

it will destroy all data. They will not be accessible anymore, not even with a more modern "vendor" image.

with data, I mean EVERYTHING on the internal storage, also /data/media ("/sdcard on older phones").

I thought everything that could go wrong would be that it doesn't boot. That was a mistake.

I think this should be written everywhere, on the OP and in the lineage wiki/download page. Even after modding phones for almost 10 years I made this mistake, thinking I am safe by making a nandroid backup to the internal storage.

There are a few reddit / xda posts about this, but I only found them after hours of googling. So please, include this to places where it can be seen.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Largamelion:
For me the solution that has always worked when bootlooping is to flash the magisk uninstaller zip. I don't reboot very often (only when I run into issues) but when I do, 80% of the time the phone bootloops and the only way to get out of it is by uninstalling Magisk, booting the system and then reinstalling Magisk and my module (I only use ANX Camera).
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Optimissimus99:
that would have indeed most likely fixed the bootloop issue.

Well, for me, that was not the issue. The real issue was that downgrading the phone seems to permanently damage /data, including the internal storage, with no way to fix the issue.

With android 9, going back to the newest release fixed this. With Android 10, it doesn't. Your data are permanently lost!

This should be a big fat warning in the OP, as I didn't know that, and many other people probably don't know about it. It makes backups to the internal storage completely worthless
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Tremolo4:
The issue of erasing all data when downgrading security patch level comes up regularly in this thread. I fell victim to it as well around 1.5 years ago. (I lost only a week of data luckily, because I make out-of-phone backups before upgrading). A few pages back I posted a warning about it again.

As can be seen from your example, this is not sufficient. It is unreasonable to expect anyone to work through this whole thread to become aware of potential pitfalls. And this particular pitfall has quite severe consequences.

And it's so stupidly preventable as well. It's not like a bug that comes up unexpected. It is (as far as I know at least) expected behavior that one just needs to be aware of.

So, I very much agree with you, there need to be more prominent warnings about this, for example in the OP.

PS: When I encountered the issue I was on Android 9 and I did try upgrading patch level again so I cannot confirm that it's "fixable" there.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Optimissimus99:
That.

Maybe the zip installer should also check if the patch level is lower than the currently installed one, and warn the user that this will have severe consequences.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] ManyPhones:
Thanks for the description! I think, I had read about that method before, but I was not able to locate the files or I couldn't acccess them (I don't rememeber the details, in any case there was a mounting error for one partition - probably the encrypted one?).

In the meanwhile I re-installed everything from scratch, which took ages. I re-enabled Backup via Acronis mobile and Seedvault Backup to my Nextcloud, so I try to save as much data as possible (even though Seedvault does not successfully backup ALL apps).

For the next time: where exactly are those - above mentioned- files located?

Hi there,

Hello,

Thx for the ROM, and i go share my experience from a dirt upgrade from LineageOS 16

I have dirt installed lineage-17.1-20200209-UNOFFICIAL-beryllium.zip from LineageOS 16 stable, Magisk, and upgraded the firmware to the last.

The process is a little tricky, i made a backup first (don't wont lose the configuration of some apps), and don't go well on the first try.

The noticeable bugs that i find whose the complete freeze of some apps and cant play some games, after cheeking the logcat i find the issue was the sound related.

To fix it install Viper(follow this guide https://xdaforums.com/poco-f1/how-to/guide-to-viper-android-10-custom-roms-t3996829).

Now everything works fine, no noticeable bugs till now.

Have fun,

TZ

will there be an update with march security bulletin soon?

(And - if somebody knows anything - will LOS 17.1 be ever released as official? right know all devices are still unofficial, it seems a bit like the whole project is getting slower with every release. )

I am not asking for an ETA , but just out of curiosity about the LOS project in general. Back in the CyanogenMod days the nightlies often started 2 or so months after the AOSP release.

I'm still hoping for an answer to my original question.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] rsaeqxzp2dj:
I have a few questions and notes here..

I wish i could increase the number of qucksettings tiles, 3x3 is not enough for me, MIUI spoiled me :/ google didnt help me too, it looks like its not possible to increase this number without making manual changes in the code of SystemSettings or whatever component is behind this interface. Is it possible to just edit a file and done? or does it need some changes in the code?

I noticed that the "Show Bandwidth Usage" in the Status Bar menu is hidden, if you search for it you can see it, but you cant really access it. Why? i really like being able to see that. MIUI has it.

Regarding the battery usage, i've noticed that even with my phone idle the battery consumption was always 32mAh, in MIUI this value could get under 24mAh, i think this phone has a high bogomips perhaps? i manually changed the CPU clock trying to reduce this usage with no luck, disabling sensors didnt help. The extreme minimum i got was 52mAh with my screen on, but my phone was super damn slow. Any tips how to make it consume less power than 32mAh?

I'm not sure how long it takes for the battery to adjust to my usage, and btw does this even happen? I have heard in some places that newer versions of Android use AI to tweak the battery usage (and i almost laughed at it because the term "Artificial Intelligence" is a huge hype nowadays lol, just wondering if they are going to say "blockchain" one day xD) but i'm not really sure.. The overall battery usage seemed worse, but i didnt test it for too long, so its not a fair comparison.

Now the notes, here is a small list of differences i noticed when comparing Lineage 16.0 to Lineage 17.1:

Minimum screen brightness seems to be correct, in LOS 16.0 for some reason it was too bright (i had to manually change it from /sys/class/backlight/...)

Menus are easier to find (battery stats for example)

h265 encoding is working

Video recording seems pretty smooth, although i did not find any app that could record at 60fps :/

Slowmotion recording works

Thats everything i noticed with 1 day of usage, i've reverted my phone back to MIUI as everything i had there is kinda important for me lol. But it was a nice experiment, i want to move to LOS in the future because i dont trust xiaomi that much, poco launcher is always trying to send some suspicious data to chinese servers as i've seem in NetGuard.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] N!co:
Ok, after less than one week i was ready with MIUI, tried to flash LOS again and it worked this time. :)

I think the reason it did not work last time was that in TWRP it was enabled to install TWRP app or To keep system read only.

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] rolandow:
I keep getting the error: 7 error when trying to flash the lineage 17.1 rom. This is the procedure I tried many times.

In TWRP, menu Wipe, Advanced Wipe, I select Dalvik, cache, system and data. Then I go back to the wipe menu and choose Format Data and confirm with yes.

Then I install beryllium-V11.0.4.0.QEJMIXM-10.0-vendor-firmware.zip.

Then I install lineage-17.1-20200209-UNOFFICIAL-beryllium.zip. This gives me error 7, with above that "xiaomi.verify_modem() failed to read current MODEM".

What am I doing wrong? The phone is new, and I already unlocked the bootloader. It says so on startup.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] pmcmm:
It seems you are doing everything right, that's what i did and it worked... Did you try other roms? Perhaps go back to miui and try again without format data?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
You shouldn't flash vendor/firmware - just firmware only.

If it was me I'd revert to the latest stock MIUI Q using miflash and start afresh.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] N!co:
I had the same last week. I had to flash firmware firmware 9.6.20 once,to be able to flash lineage.

After that i could flash the 11.0.4 again and could flash any rom after that.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] rolandow:
Eventually I got it working. First of all I edited a script inside the rom, as stated in the video that was posted here.

Basically you unzip the lineage rom. Then go to META-INF, com, google, android. Then edit the updater script with notepad as stated in the movie. I only removed the assert line that had something with the modem in it, for me this was the second line. I left all the other asserts there. Then zipped all the files again.

Then I did the exact same procedure. This time the lineage rom would flash. Then after that I had to NOT use Magisk 20.3. Because if I do that, Lineage booting image shows, a long time, and then TWRP was booted again. I did not try Magist canargy yet, because I'm not even sure if I need root. I was happy that it finally worked.

I hope other people get it working this way as well :).

Awesome news! Never expected to go so fast. Thanks for sharing!
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] knowledge@heart:
That is totally not the case.

Official MIUI has quite a few features that Lineage does not have. Still we have Official Android 9 Pie on Lineage.

For a ROM to become official, it should fulfil the device charter published on the lineage website.

So basically, every lineage feature should work properly to get that official status.

Regarding IR cam. It is not a part of LineageOS features. On pie, it was made possible because GAPPS and GooglePlayServices allowed smart lock and face detection through IR.

You can search it up. Google has removed faceunlock from Android Q. So Lineage does not have to get that working.

As long as LineageOS features keep working without bugs, nothing can stop Poco from hitting the "Official" status.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Largamelion:
Exactly what I was thinking. Face unlock has never been a LOS feature, it's always been a GAPPS feature so it should never be a showstopper. It's not such a big deal anyways since it wasn't really secure.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] :
LOS always most promising Rom

Keep support it
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] knowledge@heart:
Exactly. I used it on MIUI for the first 2 minutes. And then i rooted my device and flashed Lineage. I never tried it gain. The fingerprint scanner is better, quicker and more secure.

Google may bring back IR face unlock via Gapps in the future. But LOS is unrelated in this context.

Don't be so entitled.

Battery life on a 2 year old device is something very much subjective. I love my battery life on Unofficial Lineage 17.1, whereas your use case may be different and you might find the battery life disgusting.

Plus battery degradation is a factor we have not even considered here.

As for your DMCA thing, every xiaomi device had its builds stopped. Not all xiaomi devices have the IR sensor, still their builds were stopped. Please read before you trouble the devs. And more importantly, he already clarified that "it had nothing to do with beryllium". That should have been the end of the story.

Do not expect devs like [MENTION=455439]bgcngm[/MENTION] to spoonfeed you things. [MENTION=455439]bgcngm[/MENTION] is already doing great by supporting our device.
