I made a backup of mtd1 from my Redmi AX5 (Chinese) with nanddump tool, hope it is enough.

@love4life048 did you manage to revive your AX5? How did you brick it?

[love4life048]

I flash wrong firmware so my AX5 bricked :( I use your mtd backup to revive but the nand have a lots of bad sectors, I have to change the new nand. However I need full mtd backup (from mtd0, mtd1,…,to mtd18) to work with the flash memory prgrammer . Would you please help me one more time. Thank you very much!

The partition table of my Chinese Redmi AX5 (with the latest firmware 1.0.49 if relevant) is different from the one you sent and which is on the OpenWrt page. Maybe it's that of the global Redmi AX1800?

This time I used the script on this page that uses dd to make the backup. I had to edit the script and remove the mtd24,25 backup because they both led to error and canceled the whole operation, I think maybe it's because the partitions are mounted. I compared the checksum from mtd0,1,7 with the previous backups I made with nanddump and they are all the same so I think there is no problem. I hope it helps you.
