RAK7268CV2 erase and restore uboot recovery

Hello,

When I try to overwrite mtd2 and mtd3 to store certificates, I made a mistake and overwrote mt0 and mt1 from the bootloader.

Do you know a method to get me out of this situation?

I imagine that rak writes the flash memory from the factory serial, but with what method.

I have a dump of these 4 elements

mtd0:00030000 00010000 “u-boot”
mtd1:00010000 00010000 “u-boot-env”
mtd2:0000e000 00010000 “factory”
mtd3:00002000 00010000 “pst-data”

Thanks
