I've got a 806 router with two problems :
ROMmon corrupt and a bad IOS for the hardware.
I've resolved the first problem (ROMmon corrupt). I've download by xmodem a new one by the command xmodem -u.
Then, i'm trying to download now a good IOS image by xmodem too with the command "xmodem c806-o3sy6-mz.123-14.T7.bin" with Tera Term. When my router say :"Do not start the sending program yet...
device does not contain a valid magic number
dir: cannot open device "flash:
WARNING: All existing data in bootflash will be lost!
Invoke this application only for disaster recovery.
Do you wish to continue? y/n [n]: y
Ready to receive file c806-o3sy6-mz.123-14.T7.bin" I launch the upload with TeraTerm by : File|transfer|XMODEM|send.
The control panel stay at : Packet# : 128
Bytes transfered :0% and one minute later there is a time out. I don't understand wy the ROMmon image download worked and not for the IOS. Could you help me please.
Thank you by advance.
