Hi everyone,
I've got this new router and, long story short, followed Hoddys guide and installed latest OpenWRT 23.0.4.
I installed the kernel file and upon login I get this warning:
System running in recovery (initramfs) mode.
My guess was to install a sysupgrade found in the same page as kernel, but it bricked the device that got stuck in an infinite reboot.
Debricked, Hoddys again, this time with a chinese version of the firmware.
Got back on OpenWRT, same problem.
It seems that I had the same problem. A chinese version made into an international one. Once I've unbricked it and uploaded the linked solution above, it worked fine.
