Xiaomi mi router 3G flash memory

[Lenovomen]

Hello,

I have a super Xiaomi Router, which has broken due to an update. If I connect a USB TTL device, the recovery interface is unavailable. I'm not a serviceman, I don't know how to fix it.

How can I reprogram the flash memory?
Has anyone done this before?

You may be better served asking this one at Openwrt forums for a better level of support. Unless someone here has direct experience I don’t think you’ll get many answers.
