Beelink GT1 standard 2/16 bricked, can't boot to LE from SD card, have UART log

without more info what i would suggest would be to find the original beelink firmware for that box and start by restoring it and start over...

Usually the bl31 message pertains to ATF issues which could be a couple of different things but 1st i'd restore the box to the proper firmware to get the proper file pieces back into their bootloader and once that works be a lot more careful about what you try to flash to the box...

Head over to Coreelec, try one of their images, installing it to sd card.

Sounds like beelinks original bootloader is still not fully restored...

you'd need to check and see via the shell/serial console if its still giving you bl31 grief with the CE as well... my quess is that it is...

Try going to the maintance level of the box on boot up and tell it to clear all the flash area's and then retry reflashing Beelinks proper firmware and see if it can get you back into at least Android...

Without more info its hard to say for sure but my quess is when the original bootloader got patched to do the dualboot thing its knocked the ATF stuff out and theres still remnants of what was altered via the "boot scripts" that are interferring with trying fully restore Beelinks actual firmware when flashing... It may require manually via ssh trying to fix up the bootloader pieces...

I can see from your 1st post and log that its loading a kzaq kernel and a gxm-q201 dtb so after trying the CE thing i would check again asn see if kzaq's kernel is still the active loader and if so then the beelink's not restoring properly.(not unless beelink's actually using kzaq's kernel in the their uboot) as well i was under the impression the S912's used a gxm_q200 derivative dtb...

heres the thing tho... any uboot thats right for the box should work with NON-Android but trying to restore and run the Android meant for that box means the boot loader has to contain Beelink's signed ATF portions of the bin files to work...

Sorry i can't be more of a help but hopefully some of what i said will help point you in the right direction...

Ok, thanks.

Here is CE log, is anything you can see from it?

Do You know any commands that I can use to "going to the maintance level of the box on boot up and tell it to clear all the flash area's" ?

CElog.txt

You are trying to boot with wrong p212 dtb, this will not work. (Probably the GPU is broken.) You can run store init 3 in the uboot terminal and try to burn the uboot onto the sd card to boot from it instead of from the internal bootloader partition, but I do not think it helps.

This command full erases all eMMC.

First, try in the UART console to run the command "defenv" and then the second command "saveenv". This will reset all variables to their original state. After that, you can try to write the regular firmware via USB Burn Tool.

After that, you can normally activate the multi-boot and run the LE from external media and install in eMMC without the risk of killing the TV box.

This is already done by the aml_autoscript. Also burning via ABT would execute the "flash erase" (init 3) and thus completely remove the uboot environment from emmc, so running from devenv would actually make no sense

Did you try with disconnected UART ?

I have the same box and never experienced such a problems. Now with clean flash can you get to android recovery ?
