How to Flash openwrt on Samknows WB8+?

Hi everyone,

I have received a free samknows WB8+ which most possibly is an MTK 7621 cpu powered router with antennas. But however after searching online for openwrt support, I couldnt find any solution for flashing it. One close solution I got is

# Hacking the SamKnows Whitebox
The SamKnows Whitebox is a free router (TP-Link TL-WDR3600) provided by SamKnows to gather internet speed statistics. Ok that's great, but any person with a small amount of hacker's spirit will want to hack it to install some custom firmware to take advantage of the two gigantic antennas on the back, the USB ports and everything else.

## Step 1 : Debug mode
Root access can be obtained via a "debug mode" on the router giving you a direct root shell via telnet, amazingly simple.

* Disconnect the Whitebox from the internet.
* Connect your computer directly to the Whitebox via Ethernet to one of the four ethernet ports on the Whitebox.
* Configure your computer's IP settings to "Manual" setting the computer's IP address to `192.168.1.2`, the Subnet Mask to `255.255.255.0` and the Gateway to `192.168.1.1`.
* Turn off the Whitebox.

But trying it didnt help, also scanned the ports with NMAP, seems like they are all blocked out.

If anyone has a solution please let me know.

In any case if ttl helps, I am ready to go for ttl and mess around with it. But what type of ttl if anyone can give me pictures. It would be helpful thanks.

my SK-WB8+ pictures are attached with this.

According to the wiki page, installation is not very complicated, but requires a serial connection.

but my one seems to be WB8+ with Antennas would it work? also heard there needs some baud rate configuration how to do that? if i dont give a exact value, the terminal would not come properly right?

AFAIK they haven't figured out how to flash it.

yeah saw that post, but he is probably getting an encrypted response or something. It probably needs to be decoded. and I took pictures of the hardware and compared it with WB8 it seems to be same except for the antennas and some new heatsinks and spreaders.:

the board is the same, but this time, they added antennas, which is dumb and useless.

Flash here is the Winbond W971GG6NB-25 136pga

FCC ID: 2AGPP-SK-WB8V2

Maybe we need to make it boot to failsafe mode and debug with the serial ttl but I am not much of a expert.

did you read the other thread, and understood what the issue is ?

amirulandalib · July 8, 2023, 7:05am
