I'm a noob, can you tell me if this is the right way to install ArrowOS with minimal gapps on a new X3 nfc? (haven't tried yet)

- unlock bootloader using https://en.miui.com/unlock/download_en.html
- get usb drivers from https://androidfilehost.com/?w=files&flid=322799
- install orangefox (why people recommend to use it instead of twrp?)
- flash A.11 european firmware (V12.0.7.0.RJGEUXM)
- flash latest ArrowOS
- flash nikgapps core
- wipe data in orangefox

Here are the instructions on how you should flash the new OSS Vendor ROM since most people here are confused:

- Flash latest TWRP by brigudav
- Flash Android 11 12.0.7 MIUI firmware
- Reboot recovery
- Format Data
- Reboot recovery
- Flash ArrowOS

OPTIONAL:
- Flash Magisk
- Flash Gapps (If you're on Vanilla build & If you want custom gapps)

- Reboot system

Download link:
- Firmware: https://xiaomifirmwareupdater.com/firmware/surya/stable/V12.0.7.0.RJGEUXM/
- TWRP: You can find it on 4pda but you need an account. I'm not allowed to share it, so you have to get it yourself.

This firmware is for NFC model as I'm not sure where is A11 firmware for non-NFC model. It can possibly work for non-NFC model, feel free to try.

@SkaboXD Interestingly the recommendation has always been to format data after flashing the ROM, because as it seems a ROM does not put anything into the data partition before first boot (may have to do with device encryption as well?). That's how I have done it so far, but I guess it should not matter if data is formated before or after flashing the ROM.

Tried this method and still the folders are encrypted in twrp :/

I've never used Arrowos before and I'd like to try the vanilla (non GApps) version. In Lineageos there are a non-google dialer and message apps, are there similar apps in Arrow too? thx.

fix safetynet test fail :
+ install latest magisk
+ install magisk hide props config from magisk
+ extract printlist.zip in your internal memory
+ then run on terminal / adb shell :
- su

- select 1 edit
- select f pick
- select 3 custom

- select y yes
- select y reboot
- done

    I have tried Migrate since my phone was rooted but had issues restoring the backup. The phone got into a bootloop, so I have been forced to set everything back up from scratch again
    Not good! I haven't tried Migrate yet, it was just presented to me as an option for the task at hands, so either someone comes up with a success story, or I will have to just try all three backup methods and find out for myself if any of these is going to work.

    Just now, I installed TWRP 3.5.2_10-2 (Brigudav) on my Poco X3 NFC ... then I flashed "Disable_DM-Verity_ForceEncrypt" ... and I have no issues with the TWRP reading files unencrypted.
    Why would TWRP (any version, same as any version of OrangeFox) have any issues if you have an unencypted device???

    This whole story is about decrypting the device from recovery if your device is encrypted.

    And yes, it is a very bad idea and NOT recommended at all to use an unencrypted device, because as said before, if you lose your phone and you have any sensitive or personal data on it, you are done!

    If you have unencrypted your device because someone told you that this is the solution for the current problems with device decryption on A11 + OSS vendor, you have been given extremely bad advice!

    Hello everyone,

    I saw that brigudav updated his TWRP version to 3.5.2_10-2.
    https://androidfilehost.com/?fid=14943124697586337627
    Did anyone try it yet? Does decryption with OSS builds work? (I don't have the time to experiment with the new OSS builds atm)
    After testing, I can affirm that TWRP 3.5.2_10-2 by brigudav cannot decrypt the data encrypted with Android 11 + OSS vendor.

    Ganesh, since you're here, any information on the TWRP encryption issue after the June 9 build?
    I'm yet in the process of figuring it out. I'm completely caught off-guard by this weird issue all of a sudden as there has been literally no changes been made to the device sources nor the rom source so at this point i'm not sure what's even causing it. I've also decompiled the twrp and went through its contents but everything looks fine and dandy in there.

    For now i would suggest to make use of Arrow recovery to meet the needs of OTA updates etc.

    I'm getting the error:

    assert failed: update_dynamic_partitions(package_extract_file("dynamic_partitions_op_list"))
    Updater process ended with ERROR: 1
    Error installing zip file

    Please can someone help! Tried formatting data multiple times
    Fixed in version twrp-3.5.2_10-4-surya

    Can you tell more about it?

    Can it decrypt the the data partition with A11+OSS vendor?

    Is this what the Changelog entries from 2021-05-13 concerning android_bootable_recovery were all about?
    Like i said the Arrow recovery is only intended for OTA updates with no extra features. You won't be able to access internal data as its posed as a security risk.
    I just installed this ROM, but my wifi does not work. Any suggestions?
    I have answered and added a few FAQ's to the original post. Those who are still having difficulties switching to OSS builds have to check them out.

    As for the NFC issues they have addressed in the latest builds.

    POCO X3 (NFC) (surya/karna)

    Note: These are enforcing builds. Safety net checks pass out of the box! No need to flash magisk modules, which might in turn break the integrity!

    Builds have been unified now under surya codename for both NFC and non-NFC variants

    Tip: Select OEM -> Device,choose Arrow version, choose build type: "GAPPS" or "VANILLA" to download.

    Latest Instructions for OSS builds (w.e.f 10/05/2021)
    If migrating from pre OSS builds
    • Flash the latest available MIUI 11 firmware. (Flash global or any if you can't find your region)
    • Download and copy arrow build to a OTG prendrive or sd card.
    • Now flash Arrow Vanilla/Gapps build.
    • FORMAT DATA. (You'll loose all your data!)
    • Reboot.
    Fresh install coming from MIUI
    • Flash latest available MIUI 11 if you aren't on it already.
    • Install any suitable recovery (mentioned below).
    • Download and copy arrow build to a OTG prendrive or sd card.
    • Flash latest Arrow Vanilla/Gapps build.
    • FORMAT DATA. (You'll loose all your data!)
    • Reboot.
    TWRP Recovery by @brigudav :
    Note: This build of twrp will support decryption on ArrowOS OSS builds.

    ArrowOS Recovery :
    Note: This is a very basic aosp recovery only intended for OTA installs. Do NOT expect other functionalities.​
    * Do not use with DFE or while unencrypted.​
    F.A.Q :

    1. My WiFi, bluetooth and network aren't working after updating to OSS build?
    A. This happens if you're still on the old Q firmware. Flash the latest available R firmware and then follow the above give steps to properly flash the rom.​

    2. Unable to update OTA's using TWRP?
    A. The current available recoveries are outdated and are no longer supported for OSS builds. To have a hassle free OTA experience use the above mentioned ArrowOS recovery.
    A. Two of the currently supported recoveries are mentioned above.​

    So i haven't been around here for a while, after looking at the recent posts many seem to be confused, blaming and do not understand on migrating to OSS builds. In the final MIUI vendor builds the OTA functionality was blocked in order to prevent users from directly updating to OSS builds as it will be needing a MIUI 11 firmware followed by a clean flash. The same has been notified in our device changelogs. Every step and preventive measures have been taken, there's only much i can do from my side in clearing things up. We have this forum and community in place to help each other out, so lets not be pointing fingers here!

    Here again i would like to make it clear with a simple guide on how to migrate onto OSS build!

    Note: This update will require a CLEAN FLASH (format data), so please backup everything beforehand.
    • Flash the latest available MIUI 11 firmware. (Region doesn't matter!!)
    • Now flash Arrow Vanilla/Gapps build.
    • FORMAT DATA. (You'll loose all your data!)
    • Reboot.
    Beware that the current available recoveries haven't been updated yet to support decryption for OSS builds at this point.

    Mission Impossible in all custom ROMs !

    1. Safetynet check the bootloader status and will automatically fail if magisk is not installed (Magisk Hide ON must be applied for this) !

    2. Furthermore, now you have to install the safetynet-fix module to make your banking apps working !

    3. Finally, you must hide Magisk Manager.apk with a random name too (Magisk Settings)
    To everyone, please STOP this misconception about having the need to flash magisk in order to pass safety net. Do read the OP I've clearly mentioned there's no need of a magisk or modules for safety net. Device is certified and passes safety net out of the box without need of any modifications.

    By improper usage of magisk and mods you're further complicating and breaking things when they're completely unnecessary which end up causing unrelated issues which you end up calling them rom source bugs ¯\(◉‿◉)/¯

    P.S : I'm not against magisk, but when you do prefer using modifications do ask yourself on your needs and if you're able to rectify the issues it might generate. Isolate yourself from magisk or any form of modifications to recheck and confirm the issue before making a bug report.

    Even dev says in dec the 3rd changelog that notification led was implemented, it still doesn't work for me :(
    I'm aware of the notification led issue, its interlinked to an sepolicy denial from vendor which is quite tricky to address it while we're using the prebuilt/stock vendor. For now you can assume it as a trade off for enforcing builds. I'm working on a fix, once we start a full transition towards an OSS vendor these issues will be more convenient to be addressed.
