i will format correctly the post sorry i just felt tired because wasted all the day on it and feel exhausted
for example the usb stick gets recognized when i do a hit enter block info
(after installling drivers of course)i have all the steps done good except the #4 which fails to mount i do not know why
there is an story of another person with the same error https://forum.openwrt.org/t/mount-mounting-dev-mtdblock5-on-mnt-failed-invalid-argument/107927however i have not reboot since i have understood the reboot must be after the process, also added the wait 15seconds before mount just in case , but did not worked, my stick is detected in all the places except in
df
i suspect the post have errors because the steps in the video and in the post differ in small steps
