How to flash firmware without ssh/telnet, new branch

Hello everyone, I bought a router named Mosslink YC1801 which has hardware similar to Z Router ZR-2660, but it does not have ssh or telnet function and now I want to flash openwrt to init openvpn server. Can you help me??

Hi,

Without opening case to possibly disqualify device as soon as possible:

is there casual dmesg output from bootup in logs?
one would need ram size, flash (mtd and ubi) layout, identify soc, wired and wireless network.
Show the place where you can download firmwares.

Is the router website full of "openwrt" and "luci" strings? Maybe we can work out some deep links to get ssh.

Post in English, add Chinese original if you do not understand translation.
Also check ImmortalWrt, they sometimes run ahead of Openwrt supporting China market devices.

Please, can someone help me to build new firmware for this router?

You have to at least start porting work from documenting the device.

how would that work, in your reality, when

  • you own one, we don't
  • there's no usable info provided, to even start looking at it

https://openwrt.org/docs/guide-developer/add.new.device

This router does not support telnet or ssh

So?

There's usually serial, you're going to need it down the road anyway.

Please help me to determine serial pin

Can we get to see OEM firmwares upgrade site?

Maybe RX and TX are labelled on the other side of the board? Then you can also photograph the ICs.

I don’t know like you😂

OK, try to get the info out of OEM web interface, serial console will be needed anyway to backup and restore OEM firmware once you start programming the device. We are not yet there.

I flash firmware openwrt with zr2660 and it runs ok

that's brave ...

You did not share info to confirm devices are identical..
