BSNL Broadband: problem in siemen C2110 modem after firmware upgrade

@Mixmax12345Firmware upgrade can noway harm your modem hardware, the problem has to be with your firmware software. few suggestions...1. Be sure your PC is virus free.2. sometime it takes longer to reset ...it happened in my case ... so try a few more times with 20 seconds or more.3. If that is successful first upgrade it with BSNL provided firmware then again upgrade it with latest firmware you got.
