I'm currently using the TP-Link TL-MR6400 v-5 router and have successfully installed the OpenWrt snapshot firmware. Here's the information about my current OpenWrt setup:

I've been attempting to upgrade to the stable release using the sysupgrade command, as Luci isn't working. However, I'm encountering an issue with the following output from sysupgrade:

I'm having trouble understanding why this is happening. I've even tried performing a factory reset, but it hasn't resolved the issue. I would appreciate any insights or solutions to this problem.

Did you try the release version instead snapshot?

3

Yeah, but I got the same output. I'm not sure where I'm going wrong.

Factory reset: umount /overlay && jffs2reset && reboot now

If that didn't work then try installing older version of OpenWrt until it get resolves

This doesn't solve the problem.

I will try doing this, but I don't know where to download the older version of OpenWrt firmware, would you please provide the link?

Sorry been busy. OpenWrt Firmware Selector add your packages and build the image online. It takes like few mins only.
