How to install firmware MR600

Hello

I saw that the MR600V2 can be flashed with openwrt.
however there is no factory.bin file
I compiled ap51 under debian 11 but nothing happens in the router.
No change.

I saw that the gargoyle firmware (based on openwrt) offers a factory.bin file.
Can we patch it and switch to an openwrt version?
Can someone guide me?

Sorry for my english (french)

David

See https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=d9a3af46d8a1001223c2a327f449b7048d0fd5f6 for MR600 v2 installation instructions.

Where can I find more details on ap51?
destination ip address?
Which file to send?
Otherwise I'll switch to TFTP....

on the github page linked to ?

note TFTP requires serial.

no information on ap51 usage ....

???

What does this mean?

(Veuillez utiliser des phrases complètes.)

serial port only with TX/RX?

Please use full sentences.

Serial requires:

Tx <> Rx
Rx <> Tx
Ground/Earth <> Ground/Earth

(Merci de créer un nouveau message pour transmettre de nouvelles informations.)

trial and error ?
it can't be rocket science ...

and there's a man page - https://github.com/ap51-flash/ap51-flash/blob/main/man/ap51-flash.8

Don't work with ap51 ...
If i specified mac, same problem

I tried to reboot for enter en tftp mode, same problem.

I don't have now a serial port ...

that's the 2 option ? can't find it on the man page ...

you might want to try wireshark and log the traffic, see what IP the requests are coming from.

I have logged the trafficbut any information on port 69 UDP and TCP ...

I will find a serial port ...

I have found an serial port
The log and password found on the net is admin/1234 but i can't find root password ...

The command "setenv" don't work ...
tftpboot same problem

This router could be flashed really?

Cordially

You have logged in to the OS, not the bootloader.

The bootloader is only active for a short time after power on. When you first turn the router power on, you should see some messages on serial from the bootloader then it will pause on the line "hit any key to stop autoboot" or "Autobooting in X seconds." Hit any key at that point for the bootloader shell/CLI. If you don't stop the autoboot within a few seconds, it will go on and boot the OS, which is not what you want. You will need to cut the power and try again.

I thought ap51flash was only for RedBoot not Uboot. But that was a long time ago it may have changed.

Thanks for your response, but i have tested, same problem
i can't stop the bootloader
