[vitioc1997]

I have my innos phone for 5 months, and all worked right until today when i want to flash a new rom...
my stock rom was v1.1(Android 5.02)
i tried to update rom to v2.4 from the official innos site innos.com
from sd card and the process has stopped after a few moments...
after that i tried to update room to v3.0 from GizBeat and all was going right..
the operation was succesfuly and now when i try to start my phone , it's shows innos logo and nothing happen...
i can enter in recovery mode

How did you flash 3.0? SD or PC?

How did you flash 3.0? SD or PC?

i solved the problem, i installed ve v1.0 rom with QFIL and after that i updated to v3.0 and now all is working fine...
i had tried a lot of time to change rom with QFIL but the phone didn't boot up
and the port in QFIL was Qualcomm HS_USB Diagnostics 9091(COM4)
but i needed to be 9008 and the windows didn't install this driver...
i turned off the phone and i held volume up + volume down + lock key
and the phone did a short vibrate , the screen was black as turned off, and i connected to the pc and wow windows started install the RELINK HS-USB QLoader 9008(COM5) and after that i installed very easy the rom with QFIL
......
sorry for my bad english ))

In the future, you can also try "adb reboot edl" from adb command mode. edl mode (emergency download mode) is the mode that Qualcomm phones flash in.
