I bought an used E8450 with Openwrt ubi allready installed but the problem is that i can't upgrade it.
I can ssh to the device upload a new image and run sysupgrade or upgrade from luci and it reboots but it still shows same snapshot version ( r17443-90e167abaa) as before the upgrade.
If i start it into recovery-mode that i haven't been able to use tftp to upgrade the firmware.
I do have an PL2303 usb>serial if needed but what image should i flash?
See the snapshot link in the hardware data -
I wondered if i should flash linksys_e8450-ubi-initramfs-recovery.itb, linksys_e8450-ubi-squashfs-sysupgrade.itb or the openwrt-mediatek-mt7622-linksys_e8450-squashfs-sysupgrade.bin that is linked from https://openwrt.org/toh/linksys/e8450
To recover the device since i can't upgrade like normal.
Based on that revision, I think that that it boots into the recovery OpenWrt instance of that UBI variant created by @daniel. Revision matches the recovery installer 0.5.3
You likely have kernel crash log files in /sys/fs/pstore directory. Delete those files manually from ssh console, or cold boot the device (power off).
You might also copy the contents of the files to here.
That sounds to be correct, i had no logs in /sys/fs/pstore directory.
It was using OpenWrt2020 theme but after i changed it to Dark theme (System>System>Language and Style>) then i was able to flash mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb to the device and restore my config backup.
