I got the multitool to work again (reinstall stock Android) , and It recognize nand again, but i already tried Installing armbian using multitool (stepnand, i forgot to say before), tried with rkdevelop too (with 4mb stripped as i read on older posts), but no sucess
Installing It directly to sd card work well, but my old sdcard broke and the actual is only 4gb, and nand is 8gb
@fabiobassa @jock I'll atach the board photos, some logs about nand i got from rkdeveloptool and the stock ROM i used before below:
