Can't get S9 into download mode or recovery
 

I was flashing a new firmware into an S9 unfortunately the phone disconnected and did not finish, now I can not get into recovery or download mode, phone gets stuck in the "an error has occurred while updating the device software..." any help will be greatly appreciated.

you should force dowload mode and read pit file or reflash

Hi, how can I force download mode?

even in that present mode you can still flash it for as long as it is detected!!

Thanks, learned something new today. did not know u were able to do that, flashed and it is coming back to life.
