Hello there... Any solution you found? I am stuck with my zuk z2 in same situation ?? any help ?
I have a similar problem.
What caused the black screen? -
History:
I booted to test mode at 2.5.033 ST, the phone got stucked at this menue there was no way to get out. TWRP Restore to Nandroid bougt only black screen after 2nd vibration and ZUK logo.
I fixed the Test mode bug, by flashing the ZUI 1.9.104 ST Stock ROM via QPST.
After the phone was "repaired" I unlocked the bootloader, installed TWRP, made a nandroid backup of fully stock ROM and restored a nandroid backup from before the test mode problem.
The nandroid restore was successful, I rebooted the phone and it was "dead". Black screen, only rebooting (perioldy vibrating) there was no end, until the battery was empty.
I got no luck to reach any mode with tricky button pressing (vol+ pwr; vol- pwr; vol+ vol- pwr; usb in vol-) nor Windows detecting the phone. That's why I decided to remove the back glass cover, to got access to the battery.
Now I'm able to get the phone detected by my PC.
What I did: disconnect the battery, connect the phone to my computer, pressed the vol- button and connect the battery.
This made my PC able to detect the phone, but no I have an other problem. Windows only detects the phone as "unknown usb device (device descriptor request failed)". I don't know any way to install the driver....
Maybe anyone is able to help me or has any tip?
Thanks!
Cheers,

What id shown in unknown device.
Like ven_9102&dev_1234
Maybe with editing quallcom drivers for your device id, you can still install it.
and if luck qpst can recognize it as qualcomm debug mod

Alright bro, there is one method you can try.
http://zukfans.eu/community/threads/howto-flash-a-stock-zui-rom-zuk-z2-pro-z2121-only.57/
I assume your phone is a brick now. The only method you can use is the 9008 unbrick mode. (AKA QBST)
There are a few things you need to prepare before you save ur phone. U need to download the require application that the website provided above, after you set everything up,
make sure you download the latest 2.5 QBST rom,
http://bbs.lenovomobile.cn/z2pro/t554654/
Because ur phone wont be able to enter 9008 through software, thus u need to do the following.
1. Load the content XML fille,
2.Turn off your phone. After it's fully shutdown
3. press and hold the volume up button for 3 seconds
4. press power button while hold the volume up (press it for 0.5second and keep holding it)
5. after 0.5 seconds, plug in the usb right away
6. the QFIL tool should appear the Qualcomm usb QD loader
7. the download button should turn blue
8. flash it and wait for reboot

Thanks for your tip.
I followed your described procedure, but the phone will not be recocnized by the PC.
1st: I loaded QFIL XML file. (By the way this tut is made by me)
2nd: I disconnected the battery (The phone can't be turned off normally!)
3rd, 4th, 5th
6th: nothing happend!
7th: "-"
8th: "-"
The only way the phone will detected by the PC:
1st: disconnect battery
2nd: plug in USB (PC and Phone)
3rd: press VOL+ or VOL- or PWR button (doesn't matter which one)
4th: connect battery
5th: detected as "unknown usb device (device descriptor request failed)"

Yes, I did exactly you described. Sorry but this isn't working.
I don't know what I should do. Even a repair shop couldn't fix it.
Maybe I need to do this:

I will report the result.
OK. I made the deepflash cable.
After using it there is no difference between pressing one of the button combinations I recently mentioned (VOL+ or VOL- or PWR).
The phone will be detected as Unknown device. After intalling my modified driver to match the unknown ID, QFIL don't detect the COM Port.
Hello had the same problem, only with the difference that my battery was not completely discharged.
What has helped:
1 Start QFIL Tool
2 Press the volume +
3 Connect the original cable to the PC
4 QFIL Tool recognized the phone and I could play an original Rome.

Ps. Is now the battery cover (glass) broken?
No, I used a hairdryer, a razorblade, plastic tool and a suction cup to lift the backcover glass.
The glass is fully intact no damages.
You have good nerves. I would not have expected that.
But in the end, it does not matter if it does not start anymore.
Thank you again for your great instructions for playing and rooting the mobile phone.
I hope you get your phone back.
Mfg
Good and bad news
The guy unbricked the phone successfully, I received it today.
Now I have an other problem:
The phone is very very slow and laggy now.
The problem occurs everywere, Recovery, boot (the bootlogo laggs), booted System, also the test mode laggs now
Furthermore the sceen flickers sometimes and at the right side the sceen is mirrored sometimes.
Did anyone has an idea?
What I did today:
reflash through qfil

Hi m_atze, I am exactly in the same situation as You. After using deep flash cable method, I got "unknown usb device (device descriptor request failed)". Could You tell me what was the solution to unbrick the phone?
Hi All,
I tried to flash my phone from VZW firmware to unlocked firmware and my odin3b has been stuck on system.img.ext4.
I realized I hadn't installed the samsung drivers the first time around. I attempted to restart the phone as it was stuck on system.img.ext4 - following that my phone shows the screen:
"Software Update Failed Your device didn't update successfully. Use the Verizon Software Upgrade Assistant on a computer to repair your device and complete the update."
I'm unable to re-boot or do anything, when I hold power, bixby, volume down it presents me the warning screen before entering download mode. If I press Volume Up or Volume Down - I hit the same warning screen I typed up above. I am able to view the barcodes by pressing the bixby screen...
When I went back to Odin it still showed as "Added" when I plugged in the phone. I attempted the process again but it's still stuck on the same part.
Anybody have any suggestions of what I should attempt? I've been reading but have been unable to see any solutions.
Thanks for reading.
I Havnt played with the note 9 in terms of flashing or rooting as I have the SM-N960W Canadian Snapdragon version and there is no way yet. I've used Odin many times to flash and it can be fussy for a few reasons, I rooted my Galaxy S7 and nexus 5 and a few others. My tips would be....
First Uninstall Samsung driver.
Then Download "usbdeview" on your pc and Uninstall any previous USB connections labeled Android or Samsung or related, as this will allow you to start off as if it's a fresh connection.
Re-Install Samsung USB drivers, then....
Plug in Using stock OEM Samsung Note USB cord and wait for it to connect.
If no luck try a different USB port. USB 2.0 May work if your using USB 3.0 and it isn't.
Try a different version of odin, there are many, also running odin as administrator may help but not necessarily for sure.
If all this fails try on another computer or laptop. Make sure you only select the proper/necessary options in odin.
It sucks when things don't go as planned but that's the risk you take when you don't stay stock & update OTA. The steps I've written for you have fixed any issues I have ever run in to with odin & flashing but if yours was an incomplete flash and disconnected or interrupted mid way you may be stuck with an expensive paperweight I'm sad to say. Try contacting Samsung for proper odin version & odin settings, I wish you the best of luck. I am in no way a mobile phone technician but I've rooted many phones and always made it work. I hope you can too!
Best of luck!
flash back your official firmware to get back access to fone
if none of this works use smartswitch( it will reinstall drivers)
then tey again with odin 13.3 b using u1 firmware
also to get to dl mode power off the fone. if you have access to recovery ( reboot fone with vol down Bixby and power and quicly change to vol up bixy and pwr when you see it reboot)go there and choose shutdown phone. or let battery die and charge it for 10 mins and do while phone is off :
hold vol down and Bixby with one had and with the other plug the usb cable from rhe pc to fone.
The same problem happened with me. I wonder if anyone knows how to solve it?

Try your luck with different odin versions, different cable, different pc, different firmwares
As above first step Samsung USB drivers and Samsung USB cable .
I am unable to get my phone to load to download mode screen with warning screen. So I can root my phone. Only up and power and brisk takes me to recovery menu.
Tried
brisk and down and power then connect usb
Brisk and down then connect usb
None of these take me to the proper download mode screen. Can some please tell me what I am doing wrong.
Does Samsung Kies recognise theirs note 9 mines says device not supported.
I also getting message Connection problem or invalid MMI. How can I fix this

Hold vol down+bixby for a few seconds then connect usb to pc.
Kies only for old phone like note 3/S5. Newer phones need Smartswitch
I have tried many times and watched YouTube tutorials I cannot seem to get my phone into that mode. Maybe my phone is faulty.
Are you sure your phone is a genuine Samsung phone?
I installed android 12 beta on my Mi 11 ultra. Did not like it and wanted to install global. Installed TWRP, wiped data and instead of rebooting in twrp, I tried to enter fastboot mode via adb. The phone screen turned black. Now it is not showing in ADB, not detected by Mi flash tool, not enetering fastboot mode and not entering recovery. When I connect it to computer, there is this connecting sound but soon it is followed by disconnecting sound. Not even getting the charging screen. In the device manager on Windows, there is this Qualcum HS-USB QDLoader 9008 (COM9) when the phone is connected via USB cable to PC.
Anyway to restore any firmware on it? It is a CN version, star, has bootloadder unlocked.
EDL time? Or even worse? Is it paperweight now?
EDL time I think.

Believe me, this is reassuring. I'm happy to settle on EDL instead of paperweight... For EDL does the phone need to be opened, back cover removed and then that magic short circuit or is there a way to get it done without opening the phone?

Don't worry. When mine was EDL flashed the guy asked me to download a specific miflash version that he had the link for and the ROM of choice to be flashed. I connected the phone to the PC, he connected, asked me to put it in to EDL mode ( he will explain if your not sure) and done his stuff using TeamViewer with control of my desktop. Once finished, just rebooted when asked, all done.
need mi auth to flash
How do you put the phone in EDL mode?
can you get your phone on fastboot?

Hold both vol up and down while powering up or adb, adb reboot edl or fastboot, fastboot oem edl . You will see edl drivers load on your PC.
Thank you guys for your replies. I got it fixed and now it is rocking again. If anybody faces the same issue, please see details below.
Diagnosis: EDL mode
Signs and problems: Completely dead phone. Black screen. None of the buttons or their combinations work. Volume down plus power, volume up plus power, Both volume buttons, All three buttons. None of these worked in this EDL mode. In fact, the only sign that this phone was "alive" was the Qualcomm driver showing in the device manager when the phone was connected to a PC. There was this yellow sign even on the Qualcomm driver and the official Xiaomi flash tool failed to detect the phone due to the Qualcomm driver malfunction. Got the Qualcomm driver working (the yellow sign on the driver name icon in device manager) by disabling windows driver signature check. After this the phone was detected by the official Xiaomi flash tool. When I tried to flash the official and stock CN ROM, it did not allow me and gave the error "you are not authorized to download". Took the phone to Xiaomi service, they refused as the phone was of another region. They did not know any unofficial paid solution. Took it to local technicians. They tried but failed (ultimate multi-tool, some other tool they called as "aqua" did not work.
Treatment: Searched online and found a YouTube channel (
). Paid USD 35 and got it flashed via TeamViewer. I just sat anxiously (praying that he must not be a scammer...). He did some magic and successfully flashed the phone with the original CN ROM with the boot loader unlocked. I then was able to install the global version via fastboot as usual.
Thanks again for the free support I got here. Obliged and stay blessed

I tried this method today and it wasn't successful. It appeared he flashed it with his auth code, but it still doesn't power on. I'm so bummed because DHL won't touch the phone for less than $151 (risk of it being sent back) because seller wants me to lie and say it's a gamepad when DHL has precautions on phones being sent back, etc. requiring importer certificates.
My phone was acting strange on 3rd day: wasn't detecting charging USB cable overnight, would only charge wirelessly. I manually rebooted a bunch of times, then it detected the USB charging and would charge. About that time I updated to Miui 13 OTA update (Chinese /EN Rom) and noticed it was rebooting randomly in my pocket asking for PIN (not getting notifications) . Again got no USB charging through cable.
I was doing a bunch of vol up/down and Power and rebooted into safe mood. Rebooted again after things were 'ok' and little while later, the phone was OFF and never came back on again.
Did I put it into EDL and brick it this way? I Never flashed anything through USB until I tried the 35eur paid service dude.
Happy to see that is being fixed.
Wish it had fixed mine. Unfortunately, it didn't . Was refunded
