If you are flashing your modem with some firmware and in between light goes off and your computer goes switched off, then modems firmware gets corrupt and during the update process it’s deny and after that you have only one solution is that either you have to repair your modem from service center.

How to fix ‘Different C version. Update is forbidden’ issues in Huawei Modem :

  2. Insert working modem H1 into your laptop / computer and wait for the dashboard to autorun and then close the dashboard / connection manager. Make fully sure that the dashboard is not running in background.
  3. Perform usual unlocking procedure like : The welcome window will come, then click on next -> It will Searching Device -> Start Update -> Warning window -> enter the flash password (generate a password with the IMEI of modem H1.).
  4. From here MOST IMPORTANT STEP gets start. After entering the password, disconnect your working modem H1 and connect modem H2 and press NEXT button. Now wait for the application to complete the flashing process. Now your modem will be detected and automatically flashed in 4-5 minutes.
