I'm trying from an hour with a jump cable, but the phone is always recognized as 900E...
Can be that it's don't turn off? (I press power button until the second "blink")
Can be that i haven't the right qualcomm driver installed?
Did you exactly followed the step?
May be green and black wire are not touched properly

If they are touched properly when you connect usb to pc, pc dont recognize until you will again untouch those two wire

Then it ll be recognized as 9008 mode

It might also be driver issue
Once uninstall and reinstall adb drivers and miflash

Then reinstall them.
Miflash installs all the necessary drivers itself

Well jump cable might be the problem too.
Buy a cheap usb c cable from market and then cut that cable and flash if you dont want to destroy original cable.

Follow exactly my procedure cuz it worked for me 3 times.
Just patience needed.

An easy solution is here:
1) Inititial state is: The phone is powered on and the white LED is on. The phone is not plugged into USB.
2) Hold power button for about ~7-10s until the LED turns off and keep holding power
3) The device will turn on again and shows ZUK Logo for a short time, keep holding the power button
4) You will see the white LED again and the display is black,
5) After ~5s (less time than in 2.), the white LED turns off again. As soon as this happens, release the power button and press and hold Volume Up for 5s
Your phone is now being turned off
I ) Press and hold Volume Up and Volume Down button
II ) Connect your phone to the computer with a type-c usb cable
III) Your Phone is now in fastboot mode (release the keys)
IV) Open terminal (cmd) and type

fastboot -i 0x2b4c oem reboot-edl


Congratulations! You are now in 9008 with neither removing the battery nor breaking down an USB cable

It's what i will do. But, there is another problem. I've charged the phone all the night. This morning i've tried method again. Everything is changed. The ZUK don't vibrate anymore. Just flash the led if i press power off button (Whit this timing: ~2s ~15s ~30s ...etc keeping it pressed)
It's not regognized from PC and if I connect the cable the led starts to blink. (on-off-on-off-...).
With the method of cable I have the same results. (After i disjunt the black and green it's start to blink)
Really don't know....
I'll try to disconnect battery, if i will be able to remove the back cover.

Thanks for support!!

Yeah..My Z2 was reanimated!! I just want to add something: I didn't turn the device off again after a failed try. For me it also worked to pull out the usb plug (from the laptop) and touching the two cables together again.. pushing the plug in again ..waiting for 4 seconds and voila..I was able to flah 2.3* version.

The phone was discharged, so it's blink when i put it in charge.
I've charged it.
I've tried to force the installation of Qualcomm drivers (device settings/update driver/select manually/chosed the driver, etc... This is what happen:

upload_2017-1-27_23-32-2.png
It says: "Windows has determined that the best driver for the device already installed."
Can be a cause of the failed recognizing?

EDIT: I've tried to delete and reinstall the driver. Same issues (?)
The FireHose configuration it's right.

Don't work for me. If I re-connect it without power off it's not recognized....

Apparently everyone has to find its own procedure ...! XD
In summary, for me it's this:

1- Uninstall all the drivers (QPST / Miflash / Zuk1.0.6)
2- Reinstall in order: Miflash / Zuk1.0.6
3- Switch off your phone by holding the off button until the second LED flah.
4- Connect the blue wire and green.
5- Connect your phone to your PC.
6- After 4 seconds disconnect the wires. (Black & Green)
7- It's again Recognize as 900E.
8- DO NOT unplug the cable from pc of phone.
9- Connect again green and black.
10- Then turn off the phone.
