hi friend,
i have a vth1550ch-s2 and i flashed it with the wrong firmware same as you,
The problem was caused by flashing:
DH_VTHX421H_MultiLang_SIP_V4.410.0000000.4.R.20200221.bin
instead of
DH_VTHX421L... which is for this device.
and know its bricked, i can get any connexion working on it in NCOM or Putty or tftp server only a black screen and the red led of the power on the device, plz sir did you found any solution because i saw you have being in the same probleme before me.
Thanks
