I've used

adb -d shell get prop

Then you should get a long list of all the props, look for something about crypto, I received something about the crypto, this is what I found

[ro.crypto.volume.filenames_mode]: [aes-256-cts]

So I was sure it was a file based encryption, then I followed the guide and I complete the upgrade.

As for the guide, if your encryption is not FBE based you've to wipe your data

Hmmm ...

I flashed the recovery.img (LOS 21)

Rebooted into recovery.

Enabled adb

# adb devices
List of devices attached
2390113c recovery

# adb -d shell get prop
/system/bin/sh: get: inaccessible or not found

I just can tell that i did not encrypted the phone.

But when i choose a PIN for display lock, the phone encrypted
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] MadcapCries:
I'm sorry its

adb -d shell getprop
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] wowi63:
Ah, yes, it is

[ro.crypto.volume.filenames_mode]: [aes-256-cts]

LOS 21 did start!

I installed the new build. The notification LED does not work for me. It lights up in the settings section and while charging the battery, but when messages come, it does nothing. I've tried everything. Does anyone else have this error?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] wowi63:
I installed on my Poco F 1 LineageOS for MicroG 21. Mail-App is K9-Mail. I sent a mail for me and the LED does blink. But i had the same issue on LOS 20 sometimes.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] wowi63:
I think there is an error at https://wiki.lineageos.org/devices/beryllium/upgrade/.

I think "9. Click Advanced, then Enable ADB." should be before 8..

Otherwise i get these messages:

# adb devices
List of devices attached
215ad7b unauthorized

# adb -d shell getprop
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] WireShark87:
Well, it doesn't work with any of the messaging apps for me. I might add that when I go into the settings section and try the notification led settings, it randomly crashes LineageOS21-Settings. Only when the battery is charging or diving does the LED work properly. Otherwise it does nothing. I even tried to get it to work in Termux but nothing.

I don't think it has anything to do with this, but I'll write down that the built-in Android System WebView will continue to crash until I replace it with a downloadable one from the Playstore.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Squid84:
This on a clean flash? Formated data?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] WireShark87:
Yes, and I haven't even used the DFE. Android System WebView crashed under crDroid too, but I had no problem with the notification LED there.

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Abdel1993:
Fake news. Instagram can be downloaded on LineageOS via the Play Store and doesn't depend on Play Services Integrity. It has nothing to do with it.

I verified it just right now, with Instagram and Instagram Lite downloading and installing successfully.

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] blackby:
For all of you who did successfully manage to dirty flash, it this the correct procedure?

Given: TWRP-3.7.0-A12 with most current LineageOS 20 build and Magisk 27.0 running

install new TWRP version (V3.7.0-A12-V3 from https://www.pling.com/p/1346294/)

boot into TWRP

wipe dalvik/cache

install LineageOS 21 build

wipe dalvik/cache again

reboot

Did anyone happen to have Magisk installed and is it still working as expected after the upgrade to LOS21?

Hi, my only issue now is I keep getting slow charging when plugged in.

I had to turn the phone off so it could do fast charging.

Is there any setting i could configure to fix this?

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] HeroRicky_Games09:
When it happened the first time I thought it was a bug in my mobile data, when I got home I saw what happened.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] HeroRicky_Games09:
I'll give you a tip for future versions of LineageOS, within the profiles menu it is possible to configure some profiles to activate something in Cell such as airplane mode, Every time I get home I activate airplane mode, with this function it helped me a lot, but I think it would be interesting WHEN we disconnect from Wi-Fi for it to also do an action, Currently it is only possible to set one mode, if you want something more you need to create another profile and that is complicated.

Would it be difficult to develop something within this menu to do something leaving and entering a specific Wi-Fi?

I want airplane mode to be active at home but when outside it turns off on its own, is there a way to do that?

If there is currently a solution, what is it?

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Tremolo4:
Updated from 20 to 21 yesterday. Patched boot image with magisk and flashed as I always do. MindTheGapps sideloaded right after LOS.

Zero problems so far, thanks LOS team!
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Squid84:
Which magisk do you use? As my bank app detects official magisk, also do you need to reflash magisk after every update? Thanks
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Tremolo4:
I use official magisk, turn on Zygisk&DenyList, add banking apps on DenyList. And this module makes safety net pass for me: https://github.com/Displax/safetynet-fix

Edit: Use this instead: https://github.com/chiteroman/PlayIntegrityFix

Yes, I need to re-flash magisk every update. I've made a python script that automates it via adb. Instead of using an update-surviving non-official magisk variant.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Squid84:
Safety net is outdated now and not used, you need to pass device integrity.

The only magisk that could hide root for me was magisk alpha but I don't trust it.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] MarioRS:
Hy everyone, may I kindly ask for assistance...

I followed the upgade instruction below...

"Note: You can check if it’s FBE encrypted by running the following command: adb -d wait-for-device shell getprop ro.crypto.type. If the output of this is file, then your device is FBE encrypted!"

...but without result - nothing happened and adb did not react anymore.

Then I tried it with "adb -d shell getprop" which resulted in a long list, one of them was: "[ro.crypto.volume.filenames_mode]: [aes-256-cts]"

Does that mean, that my poco f1 is encrypted and I can proceed with the upgrade?

Another question: I understood, that I have to upgrade the recovery before updating to LOS21, right?

First step: https://wiki.lineageos.org/devices/beryllium/install/#installing-lineage-recovery-using-fastboot

Second step: https://wiki.lineageos.org/devices/beryllium/upgrade/

Thank you very much for explanation!

Best regards, Mario
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Tremolo4:
Yes, I'm aware. Some of the underlying checks are the same tho. The module I linked helps me pass everything except MEETS_STRONG_INTEGRITY which apparently none of my (banking) apps require.

Edit: Actually, some play integrity checker app now says it only MEETS_BASIC_INTEGRITY.

Maybe my banking apps are quite lenient. Maybe they only care about RootBeer, which is independent from play integrity.

Edit 2: I switched to this module: https://github.com/chiteroman/PlayIntegrityFix

And now it's back to MEETS_DEVICE_INTEGRITY.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Tremolo4:
`ro.crypto.type` should give a result...

You could try the Termux app, it has a getprop I think.

So just type `getprop ro.crypto.type` in a Termux terminal. It prints `file` for me.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] MarioRS:
Thank you, that worked: will try to update and hope for the best.

The corners of the top window are flat, the corners of the lower window are rounded. I use dark theme and would not have noticed that.

Does anyone know the following problem:

Bluetooth headphones connected during a phone call. Sometimes the microphone of the headphones is active (no noise for the other person from the rustling pocket) and sometimes, strangely enough, the internal microphone is active, so the other person understands me perfectly. This means I have to hold the cell phone in front of my mouth the whole time, when this happens. I can't say exactly when this happens. It seems to happen randomly. Is it a known problem that the selection between external and internal micro is a problem?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] MadcapCries:
In my experience, and I'm so sad to write that, audio, calls and microphone have always been a bad experience.

Low volume in phone speaker, bad microphone, the built in or the Bluetooth ones.

Listening to music was overall a good experience, it's just the phone / recording message experience a bad one.

I think that should be a Lineage os problem, not just a Poco F1
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] wblondel:
Hello,

Over the past few years, I've tried LineageOS multiple times. First with version 19, then 20, and now 21.

Unfortunately, I keep having the same problem: extreme lags for no apparent reason, terrible task-switching experience, apps not responding... When this happens, I reboot my phone and the phone is good again (until the problem comes back).

Before, I was using PixelExperience (now unmaintained) and I never had such problems. I recently went back to MIUI temporarily and I didn't have such issue either.

I don't know how I can debug this problem. I really like LineageOS but my phone being randomly unusable until I restart it is no fun 😅.

Could someone help me?

Thank you!

Is it possible to fix Play Integrity by any root method as of today? I was reading about the kernel blacklisting by Google
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Tremolo4:
Yes, except MEETS_STRONG_INTEGRITY.

With Magisk and this module.

Note that some apps check for other things than play integrity, such as "RootBeer".

Modules plural? I only use the one I linked.

Have you added your banking apps to the DenyList in the Magisk app?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Squid84:

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Mr. Almighty Cornholio:
What's the difference between Alpha and stable?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Squid84:
Alpha is a fork of official magisk. It's the only one that could hide root from my banking app, but these days I don't root I don't need it.

Hi there,

I'm currently configuring my new phone. And I have some older apps, that aren't available anymore in Google Playstore or I don't want to update them for several reasons.

They did install fine on my wife's phone (Oneplus 8T), but don't install on my Oneplus 12.

If I try to install the APK I get the error as seen in topic

"The app has not been installed because it is not compatible with your smartphone."

How can I bypass this check?

You're welcome.

The app makes it convenient to run adb commands from the phone itself. But if you're fine with your computer, then there is no need to purchase it.

Ok, now I failed (maybe finally) with the next task. I guess, with Android 14 they cut away old habits.

[OnePlus 12] TheMystic:
Is this a 32 bit app or 64 bit?

You'll need a 64 bit app for this method to work. If it is a 32 bit app, there may be other ways to install it, but I'm unaware of those.

too old apps with 32bit libs will not install, this phone is 64bit not backward compatible with 32bit apps, not sure if it is a SoC limitation or A14 limitation but I am pretty sure it will not work even with root, believe me I tried for several hours already with a different old 32bit app
[OnePlus 12] thevirgonian:
This is a bunch of BS. I specifically bought this phone because it is SUPPOSED to have Tango support that is supposed to support 32bit app backwards compatibility. Even though it was only a couple apps, I still miss them. Apparently it is only in the Chinese versions of the phone (maybe the Chinese ROMs). ColorOS, maybe. Anyway...they should allow this since they actually advertised it was a feature.
[OnePlus 12] JEANRIVERA:
Can you point to where it was announced as feature? Can you show proof of that?

Another thing? Are you talking about Tango app for video calls and live stream?
[OnePlus 12] TheMystic:
There was no announcement. It was expected that OnePlus would provide support like Xiaomi did with their Xiaomi 14 series.

Tango is a 32-bit to 64-bit Arm binary translator from Amanieu Systems. It bridges the gap between the 32-bit and 64-bit code, allowing old and incompatible apps to run on CPUs (and phones) that cannot execute such code.
