hello

my ZUK ist bricked with dark screen, no led and no reaction / vibration to keys.

when I plug it to a PC with usb, it is recognized as port 9008, but if I try to flash:

with QFIL I get saharaFail (rom image is in c:/z2 so path is ok...)

with MiFlash I get hello packet error.

Is it somehow related to driver? or EDL mode?

If I try connecting green and black wire from a USB cable, something happens but windows fail installing a driver...

So any hint is appreciated :)

none tutorial works for me other than cutting cable and short circuit. If your phone shows as diagnostic 900E or qusb_bulk than my friends only this video can save your phone as it saved mine. [YOUTUBE]

There is a

which

without

Take a wire and bend it, like it is shown in the picture (1).

1. Turn off the phone. If it is in a bootloop then go to 2.

2. Put wire on the second contact element from the left (2).

Plug it with a wire to PC (your phone must be already connected with a cable).

3. After 5 to 10 sec. unplug USB-cable with the wire. Remove the wire and plug the cable again.

4. If you are stuck on the boot, hold Power button and connect USB-cable with the wire to USB-port. The screen will be off and you will get EDL mode.

P.S. If you are afraid to connect USB-cable with wire to your PC or notebook you can do it with a charger which is connected to a wall plug.

My case :

youtube . com / watch?v=G_Sz1Fz1WQI

what do i do?

Edit : My device was recognized as cd/dvd driver ..

also, what do you mean by "extract to root on C"

also, where is qfilclick and how do i open it?

also, tell me how to open qpst or qfil i dont see them although i installed.

also, my device is not showing in both adb and miflash.

EDIT 2 : I got to know i'm stuck in "all auto test mode"

Even telling me the key combinations to reboot into normal or some other mode is appreciated.

I unbricked my phone successfully

I relocked my z2 plus bootloader without removing twrp. And my phone stucks into bootloops. The zuk loko appears and disappears.After a long time I did what I need to do.

First switch off your Phone. The led notification light should be off. Then connect it to pc. You see your phone stuck into bootloops. Don't press the power button. But regularly press the volume+ with volume-. Don't press it too long just press it intensively. If you get lucky you will succed to go to fastboot once. If you fail do it again. Trust me I'm oning this for 10 minutes then I succeeded. There is no website giving you the right method to do it.

After reaching to the fastboot connect it to your computer. Go to minimal adb. Open a command window and do the following commands.

1. fastboot devices

2.fastboot -i 0x2b4c flash unlock unlock_bootloader.img

3.fastboot -i 0x2b4c oem unlock-go

then boom you get your phone back. Don't relock your phone without flashing the recovery image of your stock rom. All the credits goes to the XDA team. What you need to open your mind for various solutions. I think i my case this is the only one solution otherwise I need to flash stock rom in the edl mode. Cheers !!!!!!

Success!!!!!!!!!!!!

[MENTION=294381]miju[/MENTION]12

Thanks man !!!!!!!

I really can't thank you enough. You don't know how many threads I visited and videos I watched just to get my phone back to life

but this was the best possible *tutorial*.

Though all of my data was deleted , but it's still better than a bricked phone :)

But consider it as a curiosity, my question (or me being a rookie with all this stuff :)) I really don't how my phone got bricked in the first place as I'm not into this custom rom stuff. All that happened was that the battery was really low , so I put it on charging and went for a nap then I woke up to this Bricked phone.

My phone was completely stock (no bootloader unlock,no root & no custom Rom)

Also as you said that you were trying to install a custom Rom .Do you think I should try a custom Rom as I find the stock UI boring and Buggy.(If yes which one is the most stable)

Again Thank You very much!!!

THIS WORKED FOR ME and my ZUK Z2 pro

Turn off your phone completely (press power long enough until no light on)

Press Volume up+down together, keep holding while you plug it with the USB cable to your PC

Release buttons once the cable is connected

You should now see fastboot screen coming up, you should be able to adress the phone with the "fasboot" command in the command line window (but adb won't work)

I needed this because: I had installed a custom rom, then TWRP and finally I relocked my phone, leaving it bricked. The only thing I had to do was sending the fastboot unlock command. And it worked perfectly!

I tried to install a custom rom by unlocking bootloader(successful) and installing twrp( failed and bricked). Was able to access bootloader and tried flashing twrp using all in one tool. It says success, but when i tried to boot into recovery it got stuck in zuk logo. So decided to use qfil and process went good. Detected as 9008 and no errors while downloading the file to the phone. Tried rebooting the device and it still got stuck in the ZUK logo. So I decided to flash again and it also was successful but now my device is not even responding. I am not getting any display, vibration, or LED notification. Any help is appreciated. ?

Thank you

Edit 1:

Should i download and try with ver 1.9.xxx version mentioned in the source. Im not sure if my pc will detect my phone as 9008 now. Will update after few hours.

Edit 2: Lucky phone was detected as 9008 and tried flashing 1.9.xx version(success) but resulted in bootloop at zuk logo(was rebooting every 15 secs)

somehow managed to get into bootloader and unlocked it using ALL IN ONE tool( success). Flashed again with 1.9.xx and turned on. Now bootloop is gone but stuck on ZUK logo. what should i do now?
