I dont know if anyone can help with this but there goes. I fiscally changed the NAND chip and now I need to flash it with bootloader and possibly more things (?) - I has 64GB, I tried to boot from SD card Multitool, but does not work, if I remove the chip, Multitool opens so something is needed to do with the NAND (?)
EDIT: I managed to start Multitool and look at the UART, here is the output:
The last 3 lines I think say that the NAND was not recognized? Maybe there is a way to "format" it by command line? (I know is not that simple)
root@multitool:~# [ 7.306662] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
[ 7.742795] vendor storage:20190527 ret = -1
[ 8.408590] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
EDIT 2: I think mmcblk0p1 is partition of the SD card, not anything to do with the Nand, more possible that is something mentioned on the firsts lines of the boot from SD.
