I would like to revert to the original factory firmware that is also based on OpenWRT on a GL-B1300 device. Could you please tell me how I can do that?
If I uploaded the factory image in LuCI, I got the message:
"Image metadata not found Use sysupgrade -F to override this check when downgrading or flashing to vendor firmware Image check failed.
The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform."
I downloaded tftpd64 (Windows), set the ethernet connection's IP to 192.168.1.1 (I have tried 192.168.1.2 as well), placed a file called lede-gl-b1300.bin in the TFTP server's folder. I set the IP in the tftpd64 program. The router was powered off, and connected to my PC through a LAN port (not WAN). I tried starting the router while holding the reset button, I tried powering it on and then pressing reset, in all sorts of combinations. Still, no success.
I also tried the DD-WRT tftp utility. I set the server to 192.168.1.2, selected the file, and tried upgrading. Still, no success. After a few times, this utility wrote: "Erasing Flash... (It may take long time, please wait.)" So I could not do any further tries. I think I also tried 192.168.1.1 and 192.168.1.2 as the computer's IP address.
I also tried pressing the reset button, holding it and not pressing it at all.
I would describe the steps but they are more or less exactly as in the guide. The only problem I had is that the device wouldn't always be accessible at 192.168.1.1 or anywhere else, but after rebooting it and my computer a few times, I managed to get it working and I uploaded the .img firmware file, which worked this time.
Hi, I am sorry for not marking this topic and not noting that the problem I had became irrelevant.
@Nik, thank you for your help. @tmomas, I do not know if this method would work for me or not, because I do not want to flash the original firmware anymore. Shall I still mark it as a solution? How can I mark topics like this in the future according to the forum rules?
Initially, I had a problem with configuring VLANs in LuCI. For this reason, I wanted to flash the original firmware and return the router. But after that I found a solution on this forum. If someone's interested, you can find the solution adapted to this router here.
