After successfully flashing this ROM and gapps, get the latest magisk from the GitHub repo:

Download the apk and create a duplicate.
Rename either file so it ends with .zip and you should now have two files:

> Magisk-v25.2.apk
> Magisk-v25.2.zip

One of the files needs to be a ZIP, otherwise you can't flash it.

> If you can't see file extensions, you need to enable it under the Explorer (View tab at the top).

Reboot to recovery and flash the Magisk-v25.2.zip file.
If it doesn't automatically reboot to CherishOS, do it.
In the main screen it should appear a new app. If it doesn't, manually install the Magisk-v25.2.apk file.

It might prompt you for some needed patching, say yes. The phone will patch itself and reboot.

Then you'll be rooted.

LMK if you need more help!
Thanks for the detailed reply, but I had already figured it out by the time you replied. This post will be helpful for my future self once I forget how to do it since Im no longer as active as I used to be in these forums.

    how do I root this ROM? it seems like the latest magisk requires a boot img. Where do I find one?

    CherishOS is an AOSP based rom focusing on a Unique UI with many customizations.

    Known bugs
    - Loudspeaker is loud and creates some echo in calls
    - TWRP recovery does not decrypt internal storage with a pin set, this is TWRP's fault, but does not affect OTAs, cancel when prompted for pin it will say its incorrect. [fixed with latest twrp]
    - Offline charging animation does not work [FIXED in 3.5.2]
    - SIM2 mobile data does not work (for dual sim users) but the sim itself works fine [FIXED in 3.5.2]
    - gyro sensor creates a drift in some games [FIXED in 3.6]
    - requires flashing atomix zip for WPA2 hotspot to work (attached) < now included, needs test. [no longer required]
    - you tell me

    Please ensure T-virus-2.0 is installed before attempting to flash this rom! follow this guide here: https://forum.xda-developers.com/t/nokia-8-nb1-full-rom-installation-guide.4349525/

    ROM


    Recovery
    TWRP:

    The Zip installer is used for easier access when flashing roms, the img is there in case you have forgotten to flash the zip and have lost recovery.


    Flashing instructions

    Clean Flash:


    1. Take a full backup of both your data and internal storage as it may be wiped.

    2. Download the ROM from above link and flash the recovery zip

    3. Download the recovery zip of your choosing and flash it if not already on latest twrp.

    4. boot into recovery and either remove rom pin or wipe internal to have it accessible to copy rom zip over (due to the decryption bug) or just use external sd card to flash.

    5. flash the rom zip and recovery zip again right after the rom zip before rebooting , it will reboot you to recovery automatically in other slot. (optional) cherish recovery included.

    6. Flash any mods you may want

    7. run factory reset from recovery, or wipe /data and /dalvik if you don't want internal wiped.

    8. reboot to system and enjoy!

    (flashing Atomix zip is only needed if you flash the .img to fix hotspot, but not with the zip)

    Installing an OTA (Dirty flash):

    1. Download the ROM from above link

    2. flash the rom zip and recovery zip and let it reboot into recovery.

    3. wipe Dalvik cache only

    4. flash any mods you had previously flashed.

    5. reboot to system and enjoy!

    (flashing Atomix zip is only needed if you flash the .img to fix hotspot, but not with the zip)

    Can you please post a log? I have not seen this issue happen on my device even after 7 days without a reboot, i will investigate
    I updated to the new build on Thursday and it's been good so far- no freezes yet. Thanks for fixing the H/W lights!

    Anyways, I'll post a log if it happens again but so far so good.

    To anyone else reading, I currently have 0 issues with this ROM- much better than stock ROM which is stuck at Android 9👍

    GPS is fine, it sometimes wants to recalibrate though. I don't know about aptx-HD but aptx works. Minimum screen brightness feels better with "Extra Dim" setting on the rom. Overall pretty stable but you should be cautious if it's gonna be a big deal for you in case of a problem. I was personally restarting phone around once a week on original software but I am restarting it daily with ROM to make sure it doesn't act weird. PS: That HD audio settings became usable when you connect the device.

    build is updated, the only change is that the H/W lights for keys should now work.

    Happy flashing!
