Hey!
Z2 owners that like to mess around with their phones are prone to get f#ked. I was there and I faced the problem some of you probably did - a hard brick. There are a ton of tutorials on how to fix it, but I believe I found a new way that doesn't envolve resetting it. I have only tried with twice on my phone, so I'm really looking forward to know if it's universal!
Scenario - Your phone has a black screen. The notification LED is on. If you hold the power button it flashes the ZUK logo and it vibrates. If you identify with this scenario, go forward!
1 - To turn off your device (if you haven't already), press the power + volume up. The phone will vibrate, flash the ZUK logo, turn off the LED and turn it on again. Continue holding both buttons. When the LED turns off again, REMOVE your fingers from both buttons right away. If done correctly, it won't come back again and the LED will be off
2 - Hold both Volume Up and Volume Down at the same time. Connect to the computer. You should encounter your Fastboot mode (with your baseband and other info blank).
3 - Go to your email and redownload the bootloader unlocker. Yes, remember that file? Use it. You can use one of those unlock bootloader tutorials online, but if you know what you're doing, here's the command:
fastboot -i 0x2b4c flash unlock unlock_bootloader.img
4 - Right after that, run this other command
fastboot -i 0x2b4c oem unlock-go
That's it. You should be able to go to the recovery (flash it again just to be sure). Try it out and tell me how it goes.
not working...phone is gettin turned off...but holding up and down..then connecting is doin nothing..it just keeps on going on and off again
This method worked for me,thank a lot of,great trick

Had the same problem and first i went to download mode by following the the below link
https://zukfans.eu/community/threads/how-to-unbrick-zuk-z2-from-diagnostic-port-900e.2856/
then i downloaded the stock firmware and followed this guide
https://zukfans.eu/community/threads/how-to-unbrick-zuk-z2-from-diagnostic-port-900e.2856/
Both of them helped.:good::fingers-crossed: hope they work for you
Please tell me the process for recover from hard brick, because zukfans.eu is no longer available.

You are in Diagnostics mode, it's pretty useless, you need to enter in EDL Mode and try a flash with MiFlashTool
Use "fastboot oem edl"
I don't know if your phone can receive fastboot commands in Diagnostics, just try...
Can you please elaborate what have you done prior to the device brick? An informative answer requires an informative question.

What about keeping power and volume +/- pressed together for at least 10 seconds?
Too, connect the charger, maybe the battery is drained.
At least try these simple things before moving to complicated ones.

Another thing to try is this, connect your phone with your computer and run
adb reboot edl
You will not see anything in your phone, just black screen.
Open miflash tool and hit refresh. See if it recognizes the phone.

At least mi flash is recognizing the phone.
You can try with a different firmware, try with android 7 firmware.
P.s. now that I see better your phone is recognized as Qualcomm HS-USB Diagnostics 900E, it should be 9008
You should try to find the correct Qualcomm drivers...
I'm sorry you have to go through this.

fyi this doesn't go in this section
That's an EDL brick, pretty easy on the U's. Of course ADB is not gonna detect it, because that mode only has the EDL connection, no fastboot or adb or anything else.
Use djkuz's EDL Tool with an U package

Hi internet,
I obviously need help. I accidently bricked my 6T again and it seems to be permenant. I tried to used the MSMdownloadtool but the tool can't detect the device. And the device is in a Qualcomm CrashDump Mode. It shows Attempted to kill init! exit code=0x0000000b do_exit. I got to go but is there a way to fix this.

You can restore you device using fastboot rom. Search for oos 6t fastboot rom.. There are guides for installation.
P.S. It will give a whole bunch of error in the cmd during installation but don't interrupt the process as your device will be restored in the end
Use Mnm tool to fix your phone. It can fix hard brick devices and guidance is there how to use .
PS: this is not right place post next time post on Q/A section.
Hold all the buttons down till it shuts off, almost a full minute. Then get it to boot to fastboot, power off. Then start up msm, then while phone is unplugged and off, hold both vol buttons for a 4 count, then plug it in. Msm will day connected, hit start. Let it finish and reboot. that's all
Qualcomm crashdump is not the same as download mode, and will not work with MSM. You still need to put your device manually into download mode.

Hold down every button till it shuts off, then force reboot to bootloader, then select power off to make sure it's off. Then do as I instructed above to fix it. Sometimes u can just run a fastboot rom to fix it, or boot twrp and flash a rom. I do this multiple times a day sometimes.

Thanks everyone who replied. The whole thing started when I tried to update my TWRP the wrong way and I got nothing better to do. I was on 3.2.3-1 and the newest on the website (TWRP) was 3.2.3-2, but I flashed the image instead, into vendor. This got me into the Qualcomm CrashDump Mode and it kept on rebooting to it as well. There was no way that I was be able to use the MSMDownload tool to recover my 6T as the tool couldn't detect my device as it was connected as Qualcomm HS-USB Diagnostics 900E not Qualcomm HS-USB QDloader 9008.
I pressed all the buttons and got into FASTBOOT mode! Then I booted TWRP, luckily all my stuff isn't corrupted and I did a Nandroid backup beforehand as well. So, I just restored my Nandroid backup and voila I got my 6T back. Thanks again everyone

If your using windows search for device manager to see what your device is being detected as. Try and reboot if your device isn't Qualcomm HS-USB QDloader 9008. Once it shows that try and update the driver, but you'll need to be a admin. Have you installed Oneplus USB Drivers?

Help I can not get in to fastboot mode. Im stuck in Crashdump mode. Even when i power off the phone holding powerbutton down for a while it will powerup again and the unlocked bootloader warning window with "press power key to pause boot" will not react to any presses.
Also booting and holding down power+down will result in the same and go to crashdump mode.

Yeah it will. You have to have the software ready to go. As soon as it's in EDL mode and detected by PC, start the flash.
Thanks for your reply I'm coming from 6t which can be difficult to get out of edl.
