Hello fellow members…
I just wanted to tell you thanks to everyone’s help I was able to fully recover the AR300M!
I basically had to flash the dump kindly provided by @misujr ,and then slowly work out all the “partitions” of both NOR and NAND to make it as new. Did not need to follow this method…the serial console was enough.
I can dig in the detailed explanation if needed, but basically the most important thing to say is that I found preferable to flash all the sections through TFTP and serial console, since the UBOOT UI has some quirks here and there. Specifically, both NAND and ART flash did not execute properly, via 192.168.1.1 and 192.168.1.1/art.html It is a bug with the size of files (at least for the NAND fw)
I found a little confusing the scripts in the uboot console, but in the end they worked. Surely, you need to rename the files in the tftp server to match exactly the ones in the scripts. In particular, the script that flashes the ART section is not really well documented, and I ended up issuing commands when a script was provided, but nonetheless I succeeded.
If you need further details, just ask me in a reasonable timelapse. I’ll try my best to explain properly, and give back what I received!
Thank you all, again. I mean it. This is a great forum and community, as much as owrt forum!
Keep up the good work.
