[Xiaomi Poco F1 Questions & Answers] michalpal:
My pocophone with stock ROM (updated) got stuck in reloading MIUI (see the video: https://drive.google.com/file/d/1-J-0UauWOrKQ2K7A7z4iJcixmU5Um52r/view?usp=sharing)

I can unlock the phone but in 10sec it dies and reloads again. After a few loops, it automatically reboots into recovery menu. If I reboot the phone, it starts again.

Is there a way how to solve this without losing all my data? Thanks
[Xiaomi Poco F1 Questions & Answers] Logeswaran B:
First data backup was already enabled means ok. Or else you gonna lose data. Because wipe data and factory reset is the only solution to stop this. I also faced this and I did data reset by long pressing volume down+power button and choose wipe data method to power on the phone with Normal use. MIUI 12 has numerous bug and sucks at battery life. You need to charge 4 or more times or else forced to use ultra power saver. Idle battery drain 35%. Don't update MIUI12.

Off-topic, but related to the topic:

Has Xiaomi already released the COMPLETE version of the kernel source code for Poco F2 Pro?

If not, does anyone have any idea about why?
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] SebaUbuntu:
With Android 10 kernel sources Xiaomi did a mess

We're hoping for a not-so-broken kernel sources release for Android 11
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] Deleted member 10374985:
I was wondering...

Whenever Xiaomi releases a new MIUI Stock Rom. Xiaomi's programmers compile the Rom and the Kernel using the Device's Kernel source code.

So, why doesn't Xiaomi release the Kernel's source code that they use to compile their own Poco F2 Pro Stock ROM? Simples as that. No mess, no problem, and no delays. I'm totally sure that the Poco F2 Pro Kernel source code they use for compiling the Stock MIUI Rom is a fully workable one and not a messy one.

Do you agree with this point of view?
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] Gingernut78:
If they do it like that XDA developers will get to see all the dirty hacks they code into the kernel to spy on us.
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] SebaUbuntu:
Note: Build repushed with brightness fix, you can dirty flash it over previous 18.1 build
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] SebaUbuntu:
They use different kernel sources, with full git history

When they release a kernel to the public, what they do is simply cloning CAF kernel, deleting everything and copying current kernel over it, then pushing it

So it may happen that some files aren't "uploaded" correctly with this method

[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] trivi88:

I have been some time away from the ROMs world. Is magiskhide already a long term solution or is it possible to need regular updates whenever Google updates safetynet?
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] Shished:
Latest version of Magisk has support for Android11, so far there weren't much changes on the google's side so the development is rather slow.

Hi all,

just to say i try this rom as a daily driver. I haven't tried gpay with nfc yet , but i will soon.

Deep sleep and battery seems good. Urnyx gcam works ok.

I am a long time LOS user and like the vanilla AOSP feeling.

I am ready to follow the updates by sideloading when they will come.
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] mehiso:
No, I have not tried to install cr on this device yet.

The overload on features crdroid offers is nice for some but distracting for others. I am more of the second type for my daily driver. On my dev phones this is a different story.

On those I mostly use something more customizable.

So if you want more options for customisation, go for crdroid and if you need a reliable, more minimalistic Rom go for Lineage.

Love that we are getting official lineage builds now, that's awesome!

On a related note, I need some advice: I have been slacking a bit with updates and am still on 2021-04-01, firmware version 12.2.5.0. Should dirtyflashing this new build be possible, or should I try all updates since april in order? I assume a cleanflash should not be necessary to switch to the official builds, right? And at which point should I flash the firmware update to 12.2.6.0, if that's even necessary?

I actually wanted to update this morning anyway, but @SebaUbuntu 's website seems to be unreachable, I get an error 403 when using the ROM/Recovery download links.

[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] jmga:
So, it should be fixable by replacing these 3 files from the ones in the official firmware?

sm8250-common/proprietary/product/priv-app/HotwordEnrollmentOKGoogleHEXAGON/HotwordEnrollmentOKGoogleHEXAGON.apk

sm8250-common/proprietary/product/priv-app/HotwordEnrollmentXGoogleHEXAGON/HotwordEnrollmentXGoogleHEXAGON.apk

sm8250-common/proprietary/system_ext/framework/com.android.hotwordenrollment.common.util.jar

EDIT: Yes, it works! Although the process is a little painful (root needed):

1. Download latest fastboot ROM and unpack it.

2. Use simg2img with the super image.

3. Use lpunpack on the new image to extract system_ext and products partition images.

4. Use extfstools to extract these three files:

From product:

/product/priv-app/HotwordEnrollmentXGoogleHEXAGON (directory)

/product/priv-app/HotwordEnrollmentOKGoogleHEXAGON (directory)

From system_ext:

/system_ext/framework/com.android.hotwordenrollment.common.util.jar

5. Adb shell into the device and remount partitions as RW.

6. Copy the previous files/directories into their corresponding paths and overwrite existing files.

7. Remount partitions as read only.

8. Reboot device.

And just like that, Ok Google works, even with the display off.

I love how everyone got excited for an Official LineageOS release!

Now we can move on from ArrowOS's lack of device specific groups, old MIUI firmware base and troublesome compatibility with kernels other than stock.

We can move on from EvolutionX and its telegram fanboyism for a narcissistic and disrespectful maintainer.

I'm sure that same fanboyism is gonna leak onto here and I'll get the dodgy comments and DM's but you know what, I stopped caring once I realised there are other ROMs with far better maintenance and stability, maintainers and dev communication etc.

I do however absolutely love the suggestion as this LOS as a daily driver and CrDroid if you want the same stability but with loads of customisation.

I think that's awesome, I'm on CrDroid now!

Actual relevant post.
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] HK-47:
You can download the full firmware from the same website, but the 133MB file is all you need. Just flash it via ADB before flashing the LineageOS ROM. No need to reboot in between. Given the amount of time (and probably changes) from the January release you currently have to this official one though, you will most likely have to perform a factory reset (i.e. clear /data and /cache) to avoid a bootloop.

I used the unofficial builds until I noticed I was having a bug with apps apps showing images with a very low dpi, like Tachiyomi and switched to Xiaomi.eu.

I found an explanation here, any idea if this is fixed with the official build?

To test, install Tachiyomi and an extension like the Manga Plus one, and try to read any chapter : if the size is way too small, the bug is still here.

In case it is resolved I will go back to LOS : is there a way to do so without losing everything in the storage partition?

Hello!

How do you guys make your google contacts sync work? Which gapps do you use to make it work? Also, when I flash los and then I want flash back for example xiaomi.eu I get error 7 or error 1 always during installation. I have to use mi flash and flash fastboot rom and then twrp again to get up and running. Of course I did format data every time. Anyone has the same problem? I really want to use los but that thing with contacts holds me back...
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] iwanova:
Maybe he referred that Arrow OS still active and always updated, which is true. But I understand your point. It still need older MIUI firmware, While I don't really care about how it lagged behind in terms of Security, Performance, etc. It's really such a pain in the a** cause it's need a full MIUI firmware, even sometimes it's not booting into Arrow even though I installed the firmware based on the installation instructions.
[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] HK-47:

[Xiaomi Poco F2 Pro (Redmi K30 Pro) ROMs, Kernels, ] fr_jason:
Thank you for trying to clarify on the person's behalf.

I understand your frustration with flashing a full MIUI firmware.

When I was on ArrowOS, I was able to flash the updates via OTA, and that was perfect because it worked for months like that.

Until it didn't.

That's when I found that there was a lack of device specific support. In the xda thread you'd have to make your post and then wait for an eventual reply, if your post gets seen at all by the relevant parties.

Then in TG channels/groups, there is no specificity for your device, so you'd have to make sure to find the username relevant to the devs/admins that posted and/or responded the xda ArrowOS thread for lmi.

While responses there are faster (TG) without device specificity, your message get buried quickly, worse now with the stickers.

That is not only for ArrowOS but for many other ROM threads/groups as well.

On the other hand, I must say, if you don't really care for the extra customisation that CrDroid offers then go for ArrowOS, it's simple, clean, a decent daily driver and ArrowOS has given me the best battery duration of any ROM I've ever used, but this was an experience from January/February 2021.

For the booting issue;

What helped me a lot was using Pitch Black Recovery with the MIUI firmware indicated by the ROM post, and don't wipe cache/dalvik

For that guy @NOSS8 ;

ArrowOS is updated quite regularly indeed.

I think you misunderstood then that I wasn't talking about the ROM version but more so the firmware base it was built on, the MIUI firmware.
