Up again :frowning:
It isn't hard to support MT 7628N if someone experienced tries it :frowning:

i hope there would be for this router..

Has three methods of attack.
one for telnet over netcat, telnet and other for ftp direct for filesystem.

Does anyone have the router to test if exploit works?

I tried it its working on firmware 2.9.217 and 2.14.45 and 2.8.51_INT
And SSH is working on 2.9.217 but I dont know the password
get the dev firmware 2.9.217 from here:

I Compiled Padavan from Prometheus for 3C

Sadly the rom I compiled isnt working
But I managed to install Breed Bootloader via telnet (Mi Wifi Nano Bootloader)
And installed Padavan precompiled for Mi Wifi Nano
Need to test all the features now

Any news on this device,
Did it worked?

Try run this exploit. it resets the root user's pw.
This exploit run over speedtest native of firmware.

Ok. This exploit worked? My english is very bad. Sorry.

Yes this worked flawlessly!
After I got access to telnet server, I installed breed bootloader (Only compatible is of Mi Wifi Nano)
DONT USE THE MINI BOOTLOADER USE THE ONE FOR NANO FROM BREED OFFICIAL WEBSITE
Mi Nano Breed Bootloader -> https://breed.hackpascal.net/breed-mt7628-hiwifi-hc5661a.bin
Instrcutions to install bootloader and Flash Firmwares->


Now for the firmware, I installed OpenWRT 19.07.2 (Mi Wifi Nano) using breed web
Its working, only problem is WAN and LAN1 Ports are interchanged so for internet I need to connect to LAN1, WAN port is working as regular LAN.

Firmware -> http://downloads.openwrt.org/releases/19.07.2/targets/ramips/mt76x8/openwrt-19.07.2-ramips-mt76x8-miwifi-nano-squashfs-sysupgrade.bin

I tried but I cannot even get telnet connection,
Please guide thanks in adv

I would like to do, but don't know how to do

Step by step guide

Did you try this?

Yes
I have ubuntu 20.04 and mi3c router attached to lan of miwifi 3c and wan attached to my main router,
I have tried on 2.8.5. And 2.8.27.

Do I need to install miwifi nano dev version first?
If yes how?

Edit

I was able to install openwrt on my mi3c as suggested above.

I should have warned you before but there are some problems
only 2 antennas are working (Mi Nano has 2) so the speed and signal strength might not be what stock offers.
Lan and Wan interchange.

Is there any way of going back to original firmware
Now you can work on openwrt for mi3c.
You can compile it.

Can u please explain how to configure router.
I have my main router which has rhcp running 192.168.2.1
I would like to adding my second router with 192.168.2.4 and rhcp to be managed by my first router.
Please guide me.
What wire tobe connected where?
Please guide

at last i got my router working,
signal are poor on openwrt, would like to suggest, dont flash it on mi3c.
it was too hard to configure than i though.
and yes only inner settings are changed, for wan and lan.
dont confuse yourself for physical changing cable on device.

Yeah, it was hard to configure it. Now waiting for some big guys to compile a proper OpenWRT or Padavan for this device. Hopefully someone notice.
