AX3600 Dual Boot Original FW / OpenWRT

Installing and Using OpenWrt
1

Dear Forum,

thanks for your support so far, that's really great

I've heard that it's possible to toggle between Original and Open WRT with a command like:

root@OpenWrt:~# fw_printenv flag_boot_success
flag_boot_success=0
root@OpenWrt:~# fw_printenv flag_boot_success
flag_boot_success=0

with the opposite (0/1) it would boot the opposite.

fw_setenv flag_last_success 1
fw_setenv flag_boot_rootfs 1

But it doesn't

Any ideas what might be wrong?

ubiformat /dev/mtd12 -y -f /tmp/openwrt-qualcommax-ipq807x-xiaomi_ax3600-initramfs-factory.ubi -s 2048 -O 2048 
nvram set flag_boot_rootfs=0 
nvram set flag_last_success=0 
nvram commit

BTW is there any way to flash back the Original Chinese FW?

Thanks

you'd need to check the boot loader params for this, in worst case get serial access.

dd mtd13 to mtd12 (or the other way around) ?

The current version of openwrt unifies both partitions, so original firmware is lost.
If you want to return to original firmware, execute the unbrick instructions of the wiki.

THX @McGiverGim ,

okay this clarifies why it is not working.
Might this also work?

Back to MiWiFi

  1. download ubi firmware (1.0.17 or 1.0.67) copy to /tmp
  2. login ssh, flash firmware
    ubiformat /dev/mtd12 -y -f /tmp/xiaomi1.0.67.ubi
  3. set ubootenv
fw_setenv flag_last_success 0
fw_setenv flag_boot_rootfs 0

Now reboot, if you back to qsdk, login ssh set boot rootfs

nvram set flag_last_success=1
nvram set flag_boot_rootfs=1
nvram commit
