[ROM][12.0][cepheus] ArrowOS [Twelve][STABLE][OFFICIAL][2021/10/31] by Lamjiidii1

I tried this ROM too, but I have problems connecting und staying to Wi-Fi. Is this a Android 12 thing because on 11 I have no problems

Try different firmware, reflash rom with full wipe, I'm using eea fw with no issues with 5GHz WiFi

Is there a way to remove the gesture bar below?

Use this recovery 11.3
wipe system dalvik data and cache
flash Arrow os
Then flash firmware, I used 12.5.1.0 eea u can also use 12.5.4 china
I also formatted data partition cuz of encrypted partition on miui
Then reboot and wait 5 min to boot
Enjoy

Thank you very much for your suggestion!
I just have a question: why flashing MIUI firmware AFTER flashing ArrowOS?
They're even a different Android version: MIUI 11 Arrow 12

I can confirm that this works smoothly so far, I didn't flash firmware at all,
I formated data before and after install rom,
battery seems same with 11 but will come back on this,
gpay works
in general very snappy, good job dev

Firmware is just a drivers

Thank you very much, I thought it was the complete MIUI firmware!
Furthermore, modding on Xiaomi devices isn't very intuitive anymore these days...

Hello,
First of all thanks you for this rom i'm using it for half a dayy for now and no major issue, i was scared about phone freezing or rebooting for m'y alarm clock but all went fine.
Just a small question, is it possible to disable 180° rotation? It's an annoying comportement inherited from MIUI.
Another question to users did someone manage to use Android 12 pixel launcher?

All OS 12 SP1A roms have the same telephony error:

java.lang.NoSuchMethodError: No virtual method isDataAllowedInVoiceCall()Z in class Landroid/telephony/TelephonyManager; or its super classes (declaration of 'android.telephony.TelephonyManager' appears in /system/framework/framework.jar!classes3.dex)

And there really is no such method in the framework. In SPB4 and SPB5 there is

@lamjiidii1 Do you have plan to add Face Unlock feature please?

 

[wallef.]

This custom rom is this good, without many bugs or errors. But the fingerprint didn't work and Battery is a little high on its expense.Otherwise ok for now.Thank you very much

@lamjiidii1 Fingerprint doesn´t work when I want to use it for unlock/authentificate app.

Sorry fingerprint is working but finger icon is about 1-2 centimeter lower then real fingerprint sensor...

For me it works, I just flashed the rom, did not root.

For me it works, I just flashed the rom, did not root.

I do only flash too (no root, no magisk....)I see only screen with text and fingerprint icon, but fingerprint "is not acitvated" I have GAPPS version. Phone unlock is working only app unlock is not working...

Fingerprint is working , try changing firmware

 

[djzelee]

Fingerprint is working , try changing firmware

I am using this version (12.5.1.0 Europe):

Xiaomi Firmware Updater

The ultimate script that provides firmware packages for Xiaomi devices.

xiaomifirmwareupdater.com

and it doesn´t work for app unlock/authorize.... It works only for phone unlock...
Which one is OK?

 

[MarcinXDA]

It doesn't pass signature spoofing on my phone. Clean installation vanilla, no root, memory not encrypted.
What can I do to enable signature spoofing?

Wait, you can flash the Firmware via TWRP? or connected to PC.

You have to flash them for the rom to work properly.

Flash the firmware on TWRP right??
