First: did the DFU see a com port in the config?
You do have to select the com port manually.
Second: can you boot to FTM?
Third: try another Edl package, some Edl have to be installed as a backup restore not via a straight flashing.
thx for quick answer!
1 see pic pls, in DFU com4
2 no can not get to FTM
3 tried 3x another packages...see log/pic from ZTE EDL tool...

Use the latest MiFlash. I've been having trouble with EDL Tool lately. Maybe it'll work. z
I'm guessing the red LED turns off as soon as you connect MultiDL correctly?
Make sure Edl tool is in the root directory of you PC or laptop drive.
EG: C:\ or D:\ as per the instructions.
Make sure you run it as admin too.
If I remember correctly the full Edl package had to be placed into the appropriate folder as per instruction (via the tool) and on the post.
@Syberclone:
I have all as you write...in root, edl package is correct/about edl package edl tool says "success = tried 4different edl package for my phone"/
I´m convinced about a port problem, log from edl tool is:
15:47:25: INFO: User wants to talk to port '\\.\COM8'
ERROR
15:47:25: {ERROR: OpenPort:5198 Failed to open com port '\\.\COM8'
I´ll try another miflash but dont believe ...:-/
just used another PC with WIN7 and now.....CHEEEEERS!!!!!!
Thx to all!

which software did give you that error? MI Flash tool? the EDL tool?
