There could be multiple reason
Does that app restored with backup? If yes then try clearing data of app.
Also it can cause if it check for root, hide in magisk
It can be with GPAY fix, try removing and see
Initially it was restored from backup. I tried from a clean install same thing. I added it also to the Magisk exclusion list, same result.
I'll try GPAY fix tips then let you know.

Thanks for the new update and keeping Note 20 relevant. I'll cry when you decide to move on from the updates lol
Lol! At least for one year no plan to stop N20development.
By the way, I own S21Ultra & S22ultra both but my primary device is still N20Ultra

What files does it contain: "AP_Dr.Ketan....tar.md5"? I can't flash it because I have bin 4, and my imeis are not the original ones.


Recognized Developer / Recognized Contributor
My imeis were not patched, they were the original ones, they were changed when installing the rom, and I can't flash the BL.Ketan files, since my bin is 4, not 3.
Then you can ignore bootloader files
If you want to update to latest then first install stock rom and then flash this rom

    I tried to flash TWRP and got an Odin error. When I booted I got the same error as before. So had to start over and flash VH7 again. I'm staying on stock until Sept. rom. :(

    ETA for S11 (Sept base) : Before Next week end.

    Thanks for patience & support.
    I am aware of Sept patch but busy with other project, it may take little time to update.
    Sorry for inconvenience. Hope all of you can understand.

    Honestly, I could wait for 2 builds before updating. Security are not important to me 🤣. Enjoy your weekend.
    Thanks a lot, I would also like to say that I have been using your roms for years on may different Samsung phones and they are excellent!!! Thanks you again.
    So, Im coming from android 11 very stock with magisk and root done the "organic" way.

    I'm following every part of the tutorial and when I get to flash the BL, AP and CS from the tutorial on the last step (after flashing super.img and installer.zip) I get the same error, when flashing everything fails because phone is on binary 4 and the one i'm flashing is 3, flashing stops and phone gets soft-bricked. Flashing stock works without any problems to recover the phone.

    Should I just skip flashing the BL then?

    I've never touched IMEI and I don't think it matters where I am, carriers don't really care, I used to run a IMEI-less phone a few years ago without any issues.

    EDIT: Also, my phone is a 985F, My guess is I should NOT install the 986 kernel on installation setup, right?

    Yes, N985 bootloader files are old, just skip flashing it

    Dear friends
    Sorry for not available on xda since nearly 3 wks because of medical urgency. Now all good but still covid situation in my city is horrible (second wave) and becauses of pending work as well too much hospital workload, it may still take one or two weeks more to full come back on xda.
    Thank you everyone for support and patience.
    After some workaround found a way to use TWRP on A12, I am in touch with Ian regarding this for final fix and public release.

    Edit : Made backup of SB1 and worked like a charm, yet restore not tested though.
