Thanks,
 
I've opened the box and looked at the memory chip and googling it shows it is eMMC (Micron Part number 4QA98 JWA60).
 
I read everything multiple times, and the instructions for NAND say to first use the Erase option in Multitool, but this option doesn't work for me either (even if we assume mine has NAND), so im not sure how to progress from here.
 
* I apologize in advance if i overlooked or missed understand any of the instructions as English is not my native language
 

Hi @gnusmag45, I'm sorry you are having issues with your board. I hope the multitool still boots after you erased the flash
Unfortunately your board has an eMCP, which is a chip that contains both the eMMC and the DDR memory. I never had the chance to test a board with such chip by myself, so it is totally guesswork.
 
The multitool has a dtb which is usually very compatible because it does not use any "advanced" features of the board, and also uses lower operating frequencies to maximize compatibility at the expense of performance. Something does not work for your board although.
 
I edited the device tree of the multitool to provide more current strength to the eMMC pins and also some other configuration that may be of some benefical effect for your board.
 
This is the dtb: rk322x-box-emcp.dtb.
Put it in the root directory of the multitool, then edit the the file extlinux/extlinux.conf and change the existing rk322x-box.dtb with this rk322x-box-emcp.dtb.
Save the conf file and try again to boot the multitool. Check if after some reboots the flash memory is detected consistently, maybe make a backup to "stress" it and see if the backup is completed correctly, but don't install any armbian image yet.
 
I suggest you to first try to burn an Armbian image directly on the sdcard and boot armbian from sdcard. This may let you upload a full set of logs (via armbianmonitor -u) to the internet and let us inspect them before proceeding to install the image on the eMMC.
Also check if the eMMC is correctly detected within Armbian after some reboots: it is important that the kernel detects it otherwise even if you install Armbian on eMMC it won't boot anyway.

After 20 tries i finally managed to select the Erase option from the Multitool and it actually let me select the eMMC partition, but afterwards i restarted the box and now it doesn't boot anymore :/ wth

@gnusmag45
don't worry about english , me too I'n mot native.
Ok let' s see what @jock suggests about this emmc related problem
And PEOPLE don't forget to put a simple like  ( the heart icom ) to help good reputation of people here.

@gnusmag45 
read again the 3ad , all infos, you will see that  some boards came with NAND and not EMMC and I guess this is your case.
You should follow the STEP-NAND instructions instead and see if this fits to you
