[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] hatuja:
I needet a clean flash anyway, so i made a Backup of everything before the first try of flashing a new ROM.

Why exactly the Installation/Booting to ArrowOS didn't work, I dont know. It seems that at least TWRP is kind of incompatible with ArrowOS, because Wittus had exactly the same issue.

The process of flashing the ROM was fine with no errors and ArrowOS started to boot up. No Bootloop or something. Indeed, those "stuck at boot animation" problems are often caused by encryption issues, as i read on different FAQs around the internet.

Since kubersharma wrote that ArrowOS recovery is changing the encryption method for the new ROM release, it is very likely that this is the cause.

So yes, for me the solution was to flash ArrowOS recovery from kubersharma's post first. Then wiped/format all the necessary partitions again and finally sideloaded ArrowOS from within the ArrowOS recovery.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] solidamage:
Everytime I try to flash ArrowOS 12 I get partition data encrypted in TWRP... Tried now with orangefox, is the same thing, how can we work around this?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] dna99:
That's what happend to me too, I just updated my Android to Arrow just a week ago, a week later, again the same work. Thats why I can just recommend everyone to switch to ArrrowOS recovery. Unfortunately it's not as comfortable as TWRP

Thanks dev 😊

Im on Arrow os 11. Rom is great all rounder. On day 1 itself im in love with its features.

Will give detailed review after couple of days or in a month.

How to change fonts to our own?

Any theme manager supported? Like substratum or something? Sorry for noob question. I just know rom is based on asop and no idea about how to change themes and all...
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] dna99:
I can't confirm that, I use the same setting and I tried different fingers than the one programmed, the phone was never unlocked.

Hello guys!

What level of widevine do you have with Arrows v12: L3 or L1 ?

This is the only reason that makes me stay on Arrows v11 right now... I read somewhere in the thread someone experiencing L3 a while ago.

Thanks in advance.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Turbine1991:
This phone cannot capture great 720p, so I worry 4k probably isn't really worthwhile.

I made the mistake of updating to that terrible Arrow recovery. And now I'm stuffed. I thought it'd be based on TWRP or Orangefox. No cables seem to work for fastboot. But ADB works. =\
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] marianico1:
How long does it take to do the first installation? It takes several minutes to bootlop. I use orange fox

How is the installation process with this recovery?

With twrp and orange fox recovery I got bootloops. I used the Arrow recovery image a few posts back in this thread and it worked fine.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] dna99:
can you give more information? How much time passes between unlockings. Do you meen, that it just unlocks once with an unknow finger (after that passed time) and then it works correctly again?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] eduardozurita:
(Indeed, it was my girlfriend who discovered it. what she does is turn off the screen and immediately turn it on and quickly press her finger on the phone screen and that's how she manages to unlock it sometimes.)

(De hecho, fue mi novia quien lo descubrió. lo que hace es apagar la pantalla e inmediatamente la prende y rápidamente presiona con el dedo la pantalla del celular y así logra desbloquearlo a veces)

Hi

thanks for the great ROM.

Some remarks that may help others.

I installed the Vanilla Version and used BitGapps for Goo.. related functionality.

In this setup I had issues with the Location Service.

With the latest clean install :( I switched to NikGapps and this issue was solved.

Generally the battery life is really good. Well Done.

One final question to the developer:

Is there any outlook for the 2 specialty cameras to work. (Tele;Wideangle)?

Hi,

I wanna install ArrowOS on my Device and now nearly everything is prepared. The last Devices i rooted/Custom Firmware(d) are from pre Magisk Time so i am a bit confused. I didn't find any download Link yet. Do i have to use Magisk Manager after setup ArrowOS?

regards

Beltar
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] mauam:
Using magisk is optional. Install magisk always after the first boot, if you install it right after installing the rom, you'll get play store not certified.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Beltar89:
Thanks for this information. But i am still missing the Installer. I think there should be a Magisk.zip for Recovery.

What i am missing in this rom, i wanna set a charge limit for Battery. And what i read, for 48MP Camera i need some Magisk Module too.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Piaer:
But even after rooting with Magisk? After rooting I have L3 and can't find a way to get L1...

Or maybe there's a modified Netlifx app allowing to run media at FHD?

Hi,

yes i already decided for this Recovery. ClockworkMod seems already out of business and i read about the Problems with TWRP.

@Piaer Where did you get the Magisk installer? Did you patch Recovery like Magisk Manager told me? I would prefer to patch initramfs but Magisk Manager could not detect.

Beltar
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Piaer:
Hello Beltar,

I installed Magisk the old school way, which means via recovery.

The last method which is not recommended (Custom Recovery)

Installation

The Magic Mask for Android

topjohnwu.github.io

I don't know if it's important but I have clean installed the ROM and just after I have installed Magisk.

1. Get Magisk from official GitHub repo: Magisk v24.3 https://github.com/topjohnwu/Magisk/releases/tag/v24.3

2. Change extension from *.apk to *.zip

3. Install via recovery (I have used arrow recovery so I had to sideload the zip

4. It worked like a charm :)

I have managed to pass safety net:

Instruction (Passing Safetynet on Magisk-v24.1)

How to pass SafetyNet? - Xiaomiui.Net

Safetynet don't passing is problem for many users. Usually you can't download Netflix or some apps on Google Play Store. Bank apps can pop-up warnings even if

xiaomiui.net
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Beltar89:
Hello Piaer,

My fault, i didn't read until end -.-

Thanks for this help.

Safetynet Passed, Widewine still L1. (Even i don't care because the Screen is too small for watching Series in Anyway)

I installed Magisk not at Clean Rom, just add to latest ArrowOS after i already setup many things.

I added one Second Packages com.google.android.gms.policy_sidecar_aps to denylist

Now i will check about my missing features.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Beltar89:
Hi,

I am not Rappel but i have working gcam too.

All 3 Cams working without a Magisk Module. Just take care about preconfigs, in common they set wrong Cam ID and it will crash. I modifed Mi-9-Wichaya-8.1-Marian-v1, i could send you if you need.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Rappel_87:

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Beltar89:
Here is the Config. If you search the String you will find some Configs. There is one for Mi9 (should have similar Cams). I used that and just modified some Values at XML regarding the ID. Could not promisse perfect results, but at least all 3 cams are working.

thanks again for the information about gcam, magisk and the installation process.

I came from MIUI with locked bootloader. So first I unlocked bootloader, flash TWRP recovery and tried to flash Arrow OS recovery. But that only brought me to stock recovery.

So I went ahead, flashed TWRP, installed Arrow OS 12, flashed Arrow OS recovery and then Arrow OS 12 again. After that everything worked :).

Is it possible to do a full backup like in TWRP by using Arrow OS recovery or what can you recommend?

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] garlinack:
Thank you for this rom, it's exactly what I was looking for. I was on 11 (no gapps) getting high battery consumption, so I switched to 12 (gapps) and idle consumption is much better.

One feature I'm really missing from 11 is the ability to completely block an app's internet access. For example, I want to use gboard because it's awesome, but I don't want my keystrokes logged so in 11 I changed the app permissions so that it didn't have network access. Is there any way to do this in 12? I have magisk installed if that opens an avenue.

Thanks again.

Has anyone tested screen off FOD?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] bigbadwolf_pig:
Installed it last night and I think this rom almost perfect for my needs. The Vanilla is lightweight plus Nikgapps core. I love that the default browser is duckduckgo. For now would rate 4 out 5, just some missing things from quick settings.

What I want to see in the next update would be a volume tile and power button tile on the quick settings, so that I wouldn't wear out my phone's physical buttons.

I'm still using the 3 button nav, so I would like to see the invert option for the back button and switch apps button, the option to assign commands on double tap, long press on buttons and lastly the kill app when you long press back button.

I've install magisk and got root. Followed this method:

https://xdaforums.com/showpost.php?p=83545095&postcount=21

SafetyNet failed. But when magisk hide is enabled it passed.

Gcam works, used this as suggested by [MENTION=5401118]MrN1484[/MENTION]:

I'm not really sure if the FOD is working, because my screen was replaced and since I've updated to firmware ver. 12, FOD never worked regardless of what rom I install. It did work when my phone was still on MIUI 11 though. Everybody that has issues with FOD:

https://xdaforums.com/k20-pro/help/miui-12-fingerprint-unlock-defective-t4122135

Battery, I don't really know how to determine if the battery is good or not, but here's a screenshot:

Overall it's a great rom, especially for people like me who just like it bare bones but with a little customization. :D

*Update: Messaging app is acting up. SMS are delayed and sometimes I won't receive any messages at all even if my signal bar is full. Already reset APN, cleared cache and rebooted. It still has that issue.
