Hey, i just activated mine Google pay..
1. Make sure that Google Pay, Google Play services, and Google Service Framework are hidden in Magisk Hide
2. in Magisk download module "MagiskHide Props Config" and "Busybox for Android NDK"
3. download "Terminal Emulator" or "Termux" and open it
4. type "su" to grant superuser permissions
5. type "props"
6. type "f" for pick a certified fingerprint
7. type "26" for Samsung (or number for Samsung if they change it)
8. type "11" (Galaxy a50)
9. type "y" for instalation

reboot and thats it, you can test safetynet for "ctsProfile: true"

Hope it helps

Me ha funcionado. Gracias :bueno::bueno:

multidisabler.zip in twrp

multidisabler.zip in twrp

Same problem .
And some A50 phone can't use the multidisabler.zip.
This gives and error and is known with the author but no solution yet.
Tried different roms but they don't give locked error.
So something in the rom triggers it, noticed when you don't install the billing app the error comes later.

For the people who got the error like me and couldn't flash the multi disabler because of an error/problem with certain types of A50 phones.
Can try this modified version for the A50.
It work on my A50 from Thailand and I can now enjoy/test this rom without a problem.

    This new version does not have the RC version yet this is working, so skip steps number 5 onwards ..
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 1. Install TWRP Recovery BTC4 (Q Bootloader)
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 2. Download the ROM and copy it to your sd card.
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 3. Enter in Recovery and make wipes (Recommended Full wipes)
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 4. Install Rom follow the instructions of the Aroma Installer choose what you want to install then reboot now...
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 5. The rom will start ,configure and enjoy the ROM (If you don't want to install mods, you don't need to do any more steps)
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 6. Once the rom is installed, we have to break the signature security in Samsung system apps.
    Download the zip SyneXOS ROM RC + Stock for A50_xx - By Zonik
    Go to TWRP and select in the Aroma Installer the RC version, now reboot the phone you will have a nice bootloop do not worry this is normal, let it restart by itself, so that it is later patched with the signature of the Stock version, once it restarts you return to twrp..
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 7. Now we go back to Twrp and we are going to select the stock version, and with this we are going to patch and break the signature to reinstall the Mod version without problems
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 8.  The rom will start after flashing the Stock version, now you can go back to Twrp and flash the RC version without problems it will start
    [SIZE="4"][B][COLOR="RoyalBlue"]>[/COLOR][/B][/SIZE] 10.  After having done all these steps, it is no longer necessary to repeat it again if you want to return from one version to another through this zip with Aroma installer. Enjoy the Rom[/B][/CENTER]

    Pressing the THANKS button does give me some satisfaction/motivation ;)

    *As the name says it is a version for those users who choose to have a custom rom without any extra modifications, this version is not the same as my other stock version where I always added some mods, here there are no extra modifications, not has Rom control. Only a very clean and fast rom !

    *For users who love having the stock Rom
    *It has no mods for which the battery and performance will be a little better

    *If you love having the phone as much stock as possible then there are no disadvantages for you
    *If you want to have some extra options like Advanced Menu, rom control, and extra options this version is not for you


    *This is a version based on the pure stock version but with some extra modifications

    *For those users looking for a stock rom but with some extra features
    *Get new options that the pure stock version does not have

    *I think there are no disadvantages, maybe a little less battery when applying some mods (But this is something minimal)

    Note: It takes a lot of work to make these 2 versions, if you finish reading all this GREAT!!!
    So now you can decide which rom is for you !!

    Update SyneXOS v2.0

    Hi guys, I come with a new update and many news that you can see in the changes of the Rom.
    Immensely thank for the time and dedication to my great Testers @muhamet @RandomAJL @Fernando Sanchez @gabong that thanks to them the Rom has been improved in every detail.
    After v1.0 I started to work on a new update and offering OneUI 2.1 for this Device
    Without more to say here I leave you all the changes of the new version

    SyneXOS v2.0.

    > Rebase A51 libs and framework support to OneUI 2.1
    > General improvements
    > Changued model A50 to S20 for more compatibility in apps
    > The installation of the Rom is now faster and with Aroma Installer
    > It is no longer necessary to use the multidisabler zip,
    and the forced restart to start the Rom
    > Fixed some issues with security apps
    > Fixed scroll animation (Will improve performance in rom)
    > More Bloat Apps that were not working have been removed
    > Fixed Netflix
    > Maybe other things I'm forgetting to add

    Features Aroma Installer

    > Bloat Apps Menu

    -- Choose if you want to install or not Game tool,SounCloud,Samsung Billing,
    Samsung Bixby Routines, Samsung FM Radio, Samsung Galaxy Store
    Fine Lock + Extras

    > Extras Features
    -- Choose many functions like Clock App, NFC Service, DPI Feature,
    Sound Mode, OMC Features, Netflix Fix

    > Samsung and Google Menu
    -- Choose if you want to use Samsung apps or Google apps, both working very stable.

    Note1: Note : The phone is recognized as an S20, do not update the Camera does not work after the update, uncheck auto update camera, the rest of the apps you can update without problems

    Note2: The RC version is not recommended to use it in this version, so the link will be removed ...
    I have to work the mods based on this version, so I will come soon with news for this version ..
    Install the rom with full Wipes (Wipe internal memory is not necessary, but if you want to do it with this no problem, no dirty flash)

    That's all guys!
