My situation is similar to
, but even worse. Now, the V20 only gives the following responses after scrambled screen appear, at that time the modem port still active, so I use UPPERCUT + LGUP + H990DS20b.kdz try to update partition one by one, but I selelected aboot, kernel, and a few then press "go" accidentally. After such mistake, my V20 keep quiet. And only have respond.
Battery on, volume up ... black screen no respond no serial modem
Barrery on, volume down ... black screen no respond no serial modem
Battery on, power on .... virbrate for 1 second black screen, no further respond no serial modem
Batter off, plug in power show an icon with no battery, then icon disappear after install the battery.
try different combination of button, battery on, power plugin and out. Still can't show serial modem or Qualcomm device.
Did I hard brick my V20 and say good bye? Any other software and way to save my life?
Thanks in advance.
