I have bricked my linksys e8450 router and from retracing my steps I am mostly sure that I first flashed the dangowrt firmware:
openwrt-22.03.1-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery-installer to the router then via web browser luci flashed from the openwrt firmware selector page:
openwrt-23.05.2-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade
this bricked the router, upon connecting via serial port, trying to boot router first the router gives uboot options, after that, getting this:
NAND read: device 0 offset 0x2300000, size 0x2000
8192 bytes read: OK
[do_read_image_blks] Image format error,neither FIT image nor old image.
Bad Magic Number.
NAND read: device 0 offset 0x2300000, size 0x0
0 bytes read: OK
bootm flag=0, states=70f
Wrong Image Format for bootm command
ERROR: can't get kernel image!
MT7622>
Would using option 1 be the correct option to flash openwrt-22.03.1-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb from the dangowrt github page unbrick my router?

If I flash the wrong recovery image could it potentially overwrite the boot loader and make this worse and if so I assume there is no way to find out which version I originally flashed?
