Suddenly, I can no longer flash my fritzbox 7530 (ipq40xx). I have created an image with a custom config in the squashfs. However, if I flash the fritzbox 7530, everything seems to work, but after a reboot everything is the same. I was not even longer able to boot via tftp into an initramfs. Any idea what I could try?
Can I somehow manually dd the image to the flash?
Never use dd on NAND flash, you need NAND aware tools for that (nandwrite, mtd, sysupgrade, etc.).

Thanks. I was able to use a vm and recover fritz!box os with the recovery tool. Afterwards, I flashed 19.07.7 and then 21.02 and everything worked. Than I flashed an image I created with imagebuilder (openwrt snapshot 21.02) with some config. Afterwards, I was not able to flash a different image. Now I recoverd again with the fritz!box recovery tool. I want to try 21.02 -> 19.07. However, I am not ble to start initramfs boot again.
I am on 21.02.0-rc3 with a FB 7530 so i don't know if this helps?
Here's my dmesg from 21.02.0-rc3 https://gist.github.com/francisuk1989/848df6e5b44d2e030ba9dfd36b7e3580
