Dear Sirs, please help me if it is possible to save my FRITZ!Box Fon. It is annex A with HWRevision 64. I have do this: echo "HWRevision 58" > /proc/avalanche/env echo "ProductID Fritz_Box_FON_AnnexB" > /proc/avalanche/env echo "annex B" > /proc/avalanche/env and after this i have try to use the recover firmware for annex B. The firmware upgrade finished fine but the router not have now any interface up (i canot connect via telnet ftp web. Also i canot ping the router ip). I have try to re-upload the annex A firmware but say that it is for other hardware version. It is possible to do a force upgrade with the annex a firmware so i save my router? Thanks for any help and happy new year.
