Hello, after flashing my A20e (A202F) is stuck either at the start at the Samsung logo or after it boots all I get is a lighted black screen. I tried restarting the phone several times and I tried installing this custom rom 2 times. After installation I am never able to get back into TWRP.

I suspect I may have a problem with the custom Eureka kernel, because I tried a few custom roms for A20e based on the Eureka kernel and I always have the same problem. Moreover, I never had this problem with GSIs (which do not have a kernel).

So, each time I tried installing this rom or a rom based on the Eureka kernel I started from the custom rom, phone unlocked.

Afterwards, I installed with Odin (in the AP field) TWRP, as I did with other GSIs, did a clean wipe (cache, dalvik, data, system) and then flashed your rom and rebooted to system. A second time after flashing I rebooted to TWRP, then rebooted to system, but the same result, basically a soft brick.

Apart from this custom rom, I also tried the following:

Could you please tell me if I need to do some additional steps in order to solve this?

For example, was I required to root the phone with Magisk before flashing the custom rom? At least with the latest version of the stock rom Magisk is not able to patch boot.img. I remember that with an older version of the stock rom I was able to root with Magisk, but I don't remember if it was Android 10 or 11...

For bricked devices or in boot loop

To go to download mode

Normal method
1. Turn off phone
2. Hold down both volume keys
3. Plug in computer

Bootlooping
1. Plug in to computer
2. Hold down both volume keys

For a difficult phone
1. Connect usb to computer but not to phone
2. Hold down all 3 keys
3. When it buzzes release power and quickly plug in usb to phone.
It might take a few times to get it right.

If it's REALLY BAD
1. Wait for the battery to completely run down and use normal method.

Once in download mode you can flash the stock rom.

    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.
