Anyone else getting “signal 7” when flashing through TWRP? Even though it’s the A20 ROM it doesn‘t seem to like it for whatever reason

Edit: Fixed it by editing the “build-script“ file in the zip, now works properly, though Galaxy wearable and my watch is the most jank setup possible

thought i might ask, im also using the A205YN, but I cant actually get the ROM to boot unless i first flash an A11 based rom then move to this. what are you using if you dont mind me asking
Start with your stock rom then follow the steps in this forum also make sure you're using the official TWRP because it shows all the partitions you need to wipe. then once you've flashed it you have to make sure you flash dmverity. or usually whenever you get stuck in the bootloader you flash dmverity and it fixes it. You can download dmverity from here. https://zackptg5.com/android.php#disverfe

For release 2021-10-18 at A20e (SM-202F) everything works perfect except:

* No NFC.
* No FM radio app.
* The second SIM card works fine but it does not appear in the «SIMs» list (Settings > Networks & Internet > SIMs) so there are certain parameters that cannot be configured.

Thanks for your effort.

Your description says flash magisk (optional) - do you have any tip on how to do this as we do not have and likely will not get an official Android 12 firmware on this phone. So does that mean - no root for us?

The only minor inconveniences i found were
-Default Smallest width is at 411 dp while the stock on the a20e is at 360 or 380. It just makes everything larger.
-The boot animation is a bit too big and some of the end text is out of frame.
-The default wallpaper app that can be accessed from the home screen is not installed (could be a fault in my phone only).
Other than these few it stutters a bit sometimes but it could be the fact that we are trying to run Android 12 on a device that came with Android 9 at launch.

    Keen to try this. Anything not working? BT calls? NFC?
    Everything works. Except when I'm using USB DAC it can detect it but cannot output the media through it.

    I flash the dm-verity file right after I do a clean wipe. Then I flash the ROM, Google apps and Magisk.

    It works for me that way.
    didnt see this but ill try this now and lyk
