on my side 192.168.1.1/32

Nope...@daniel's instructions said 192.168.1.254/24

Go back and re-read that thread.

Glad it worked out.

In would highly recommend that you bookmark these three posts of @daniel's from the other thread...they were the actual solution.

Orange light with Linksys e8450 after snapshot update

Orange light usually means that the bootloader didn't find anything usable in the flash and is hence falling back to TFTP. This can happen if you have flashed non-UBI sysupgrade image on a device which uses UBI or in any other way managed to kill even the recovery image stored in flash (not to be confused with failsafe mode, the recovery image allows to dual-boot into initramfs to flash or fix things in case the production image has been broken). failsafe mode is not available at this point, a…

Yes, as the installer has to replace everything to make UBI work from bottom up, it also comes with a replacement U-Boot loader built from source. I took that opportunity to do some things there the vendor loader doesn't (apart from supporting UBI): allow to trigger TFTP or booting into on-flash recovery by holding RESET button the loader now validates the complete image before booting it (vendor loader only validates kernel, but not the rootfs) include netconsole (needs to be setup in U-Boot…

You need to give you PC the IP address 192.168.1.254/24 as that's where the router will request the image from via TFTP.

ubidetach -d 0
insmod mtd-rw i_want_a_brick=1
mtd -p 0x200000 write /tmp/FW_E8450_1.0.01.101415_prod.img /dev/mtd3

For this to work you would also need to write the backup files. Writing only the vendor firmware alone cannot work. You will also need to revert back to the vendor preloader, U-Boot and devinfo (ie. /dev/mtd0, /dev/mtd1 and beginning of /dev/mtd3).

Dear @daniel , I don't have backup files, is there any possibility to go stock firmware for me?

[daniel]

The installer should have generated backup files, see

mkdir /tmp/boot_backup
mount -t ubifs ubi0:boot_backup /tmp/boot_backup

If you have re-run the installer after already having OpenWrt installed without copying these backup files off the device, what you will have is just a copy of the previous OpenWrt bootchain (rather than the vendor bootchain).
You can easily verify that using

hexdump -C /tmp/boot_backup/mtd3

If you see anyting related to UBI there, the backup files are of no use.
In this case, contact me via PM, I can share a copy of my backup files with you if needed.
