Fritz!Box 7170 reboot loop, recovery

[arapax]

Hello,

Sorry, my German isn't that good so i rather speak english to make myself clear, i hope this is not a problem. The other day i was playing around with my old 7170 first trying to install OpenWRT on it, without succes and flashed it back to the orignal firmware using adam ftp and i could acces the original firmware again.

Somehow after repeating the procure a few times with different builds of OpenWRT i must have accidently touched something essential and now the modem starts booting, but after a while it shuts down a reboots again. My guess is that mtd3 and/or mtd4 are damaged. I hooked up a serial cable this is the printenv output:

When i try to recover with the recovery .exe file from avm it says the firmware is not compatible with the recovery firmware. Is there any way to find out if mtd3/4 are damaged and how can i recover them. I don't have any backup files of these partitions.

I can still ftp to adam ftp during startup so i can flash the mtd if needed. If you wish i can include a dump of the boot sequence from serial console.

Could anyone help me recover this box?

Try ruKernelTool. If you have changed some parameter recover will probably not work because a different setting is expected. The ruKernelTool will set those parameters correctly.

Hi after some issues with the network adapter in ruKernelTool i got it working with a hub in between the fritzbox and the pc to get the nic up. I flashed the router with the latest firmware using ruKernelTool and the box is back up and running. Thanx!
