Topic: Possible new device Lenovo F800 wifi external drive

The content of this topic has been archived on 6 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Maybe someone is interested - lately I bought Lenovo F800 wifi external drive for 50pounds
SOC: MT7620N
8MB Flash
64MB Ram
1TB sata disk connected I believe by sata-usb converter when working on wifi or usb3 when wired
4Ah internal battery which can be used to charge your phone
USB3, ethernet, wifi

Device runs linux out of the box - there is a possibility to login with telnet  user:root pass: 20080826
Tried to install openwrt build for hootoo tm-02 which flash partitioning is very similar and root password is the same, but I bricked the device - after that I opened it and found out that it's a different SoC. lenovo f800 is MT7620N and hootoo was Ralink RT5350F. I think it was the cause for bricking it. I managed to restore the original firmware with bus pirate and now its working with stock.

I found some time to play with the unit, maybe someone is interested.
Serial port is under the sticker when you remove the harddisk, looking from ethernet port there is GND, TX, RX 3,3V - 57600 baud and that's the uboot output and kernel boot messages:

The discussion might have continued from here.
