I downloaded the files and try to put them in the router using tftp. But without success. I use the docs pointed to by the page you gave to me. I tried to change the interface to 192.168.0.69, I check that the tftp server is listening, but tcpdump does not show any thing which could show that the router tries to load anything.
So, I'm stuck there...
Do you know where I could find a working doc for this router?
I am new to this router AND to openwrt...
And this one is more sensitive for me, because I bought it for it's 4G but the different pages I saw tells to not change the default IP to 192.168.0.x because the 4G interface uses this one.
So it is unclear for me how to use tftp for this one. Form what I understand, it is supposed to come on my computer to read itself the file, I suppose the name should be mr6400v5_tp_recovery.bin.
I tried to put it also, but without success.
So, If you could give me some hints, it would really help.
