Your 8mb flash probably isn't enough to fit a snapshot with luci.

8mb devices will be EOL:ed by Openwrt, when 23.05 retries.

FYI, 64mb isn't going to leave you a lot of headroom for additional applications once Openwrt have booted.

Plainly put, don't do it.

U-Boot downgraded from version 1.1.3 (May 26 2023 - 19:28:31) to 1.1.3 (Jan 20 2021 - 08:57:20)
How did this happen? tp_recovery shouldn't change u-boot.

9

It was a mistake when I retrieved the original frimware tp_recovery and then upgrade with different frimware V5 but my version router 5.30
can restore u-boot :frowning:

10

I found the same device mr200 5.30 Can I take a dump from him and flash on my device ?
