I had to update the “uboot firmware” ITSELF, before I could flash the “Nand firmware” as the latter was failing everytime (I was in a infinite boot loop!) I found this reference to flashing the “uboot’s firmare” (192.168.1.1/uboot.html) ITSELF here: AR-750S Uboot recovery not working - #25 by kyson-lok .
That was successful and then i was able to flash the “Nand” firmware successfully.
NB. I did NOT have to use windows to flash the uboot firmware. I used firefox with gnu/linux.
Unfortunately, I flashed the (root/firmware/ar300m/nand/v1/openwrt-ar300m-ubi-3.024.img) and am wondering why I have no 5ghz wireless. The radio is not setup in the advanced part of the router GUI. Hmmm. Should I flash the version you suggest or can you supply a config that will set the system to default? Maybe, I should just add the radio1.network1 as the 5ghz. I must say that this is over my head already.
Is there a detailed tutorial somewhere?
Please advise. Thank you.
***EDIT: Changed firmware/ar300m/v1/openwrt-ar300m16-3.024.bin to root/firmware/ar300m/nand/v1/openwrt-ar300m-ubi-3.024.img
