Hi all, after trying to make some changes to my openwrt install on my RT3200 it seems I've mucked things up a bit. A few months ago I followed the directions on https://github.com/dangowrt/owrt-ubi-installer and everything seemed to go okay:
Apologies if this issue has been covered already in the forum, however I haven't been able to apply any of the given solutions correctly yet. Many thanks for any advice or ideas anyone can send my way.
If you used the old installer that doesn't update the ECC format of the factory partition, using a new build the 5 GHz radio will stop working because the factory partition is in the old format which is now not readable by new kernels. The fix for this is to run the installer again using the new version of the installer.
This model is supported in 22.03 release builds. I would use the 22.03 release build unless you really need something that is only in snapshots.
Thanks so much for the suggestion, I tried flashing linksys_e8450-ubi-squashfs-sysupgrade.itb but it seems like all the aforementioned problems persist.
Thanks guys, looks like I've got it figured out. First I booted into recovery mode by holding the reset button while turning the router on, then I first installed ubi-initramfs-recovery-installer.itb
from the github, followed by the squashfs-sysupgrade file. Looks like everything is now working smoothly.
