@blue-wavenet - Yes, I did flash the ‘clean’ version - I guess that is wrong.
@kyson-lok - Sorry for being so ignorant about this, but I did read the readme.txt in https://www.gl-inet.com/firmware/ar300m/ and it seems to say something different:
Nand firmware is in “nand” folder. Normally what you use is in this folder.
All other folders is for Nor firmware. For example, “v1” is our stock firmware for Nor flash and “tor” is the tor firmware for Nor flash.
Also, when I try to flash a file from the v1 folder I get the message:
The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.
Could somebody please point me at the ‘exact’ file I need to flash to recover my router?
Thank you in advance.
Edit: I did try this file: https://www.gl-inet.com/firmware/ar300m/nand/v1/openwrt-ar300m-nand-2.264.tar but it still does not have the normal UI, only luci.
