New Router from china with mt7981 and mt7976 6 antennas

For Developers

Device mediatek,mt7981-spim-snand-rfb-wr3000k
I got i new router from china named like above its originally named only wifi6 ax3000, i asked them to install latest openwrt but they installed snapshot version, so i got many problems setting up v2raya library. It has about 300 mb of total space on which i wanted to install v2raya, but unfortunately df -h command which i used to see partition shows me this :
"
root@OpenWrt:/tmp# df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 13.3M 13.3M 0 100% /rom
tmpfs 240.4M 13.9M 226.4M 6% /tmp
/dev/ubi0_2 23.3M 672.0K 21.4M 3% /overlay
overlayfs:/overlay 23.3M 672.0K 21.4M 3% /
tmpfs 512.0K 0 512.0K 0% /dev
"

So is there any way to enlarge or repartition to make /overlay bigger than 23.3Mb because v2raya is about using 42mb which i have in other partition ( /tmp)
I would tell any necessary information about this router and what it has.

If needed i have a rt809f and rt809h programmer to write flash with programmer, I'm new to openwrt and don't fully understand everything, usually do mistakes, please kindly understand me))

6

That isn’t a genuine OpenWrt revision number so this image is something they have built themself.

Is there anyway for us to build another latest openwrt with v2raya and openvpn included ?

8

Have you looked in the ToH on the webbpage if OpenWrt support the device?

9

Yes, it supports Openwrt , mt7981 support openwrt firmware. Even latest firmware it supports

10

Then it is pretty much just to download, install and rock-n-roll with what you want to do.

But it is probably easier to use stable release instead of snapshot if you want to install packages since the packages for snapshot only work for about 24h or until the next snapshot is build.

11

What if i use backup and upload all necessary firmwares from router and send here , will you look what can i do with them?

12

At least, can you help me to flash it to latest openwrt version or to build new openwrt firmware for this router?

13

one antenna is fake, most likely

14

This statement is based on what ?

Your device isn't running vanilla Openwrt, so no, it doesn't "support Openwrt".

I'm not sure, maybe i forgot to correctly plug one antennas plug, but here is 6 antennas and 6 plugs as well

16

I'm not sure it's Vanilla or something other , but here is written openwrt wireless freedom, snapshot..... etc

Many companies take OpenWrt and then heavily modify it for their own router devices. This is possible because OpenWrt is free and open source. Just like you could create your own custom adaptation of Hamlet or Macbeth any public domain literature if you wanted. What results is no longer the work of the original author(s), it is a derivative work that is "based on" the original (aka: a fork).

In the case of what you have there, it is a fork that was customized by the manufacturer of that device. The vendor probably did not contribute their modifications back to the official OpenWrt project, so we have no idea what they changed/added/removed. As such, it isn't possible to support it here.

Well great thanks for explaining me , i didn't knew it , i will complain to Chinese about this.
As a request, let's get back to my main issue, how can i make repartition and rearrange space in the router not bricking it, i have a second one too for my friend which i didn't give because we both wanted to use v2raya vpn on it, so let's make everything possible to install v2ray on it, i installed v2ray - core - mini but couldn't install luci - app- v2ray because dependencies like iptables-mod-tproxy i can't download, please understand me, in our country turkmenistan, internet is very badly censored , when i enter command opkg update it's only saying connection error because or country restrictions, can anyone send me iptables-mod-tproxy.ipk please?

19

That is a question for the vendor. Again, because we don't know what they changed, we can't give advice with any confidence. What we know about official OpenWrt might or might not be the same on your device and might even cause you problems.

Not from the official OpenWrt repos insofar as it won't be compatible. You are welcome to download the source code and compile it yourself assuming you can get a copy of the vendor's SDK (which will be required for this).

How to do it ?

21

It's okay if i brick it, i will use programmer and just write firmware from second router if i will brick it, now i just need iptables-mod-tproxy for luci
