ZTE Axon 7 Unbrick Guide ( QD-Loader 9008 EDL )


Stuck at boot logo? Or done anything wrong and your Axon 7 is hard bricked ( Qualcomm QD-Loader 9008 mode )? No sign of life? Or you just want to go back to stock ROM? Here is your guide..

Actually, I had written the guide before, many times indeed, here the latest that you can read and apply to your ZTE Axon 7 ( A2017 and A2017U ) , :

Here is the latest 32 & 64bit MiFlash that you can use in any Windows operating system higher than Windows 7,

Download MiFlash 32 & 64bit New Version

Here is your service ROM :

Unbrick ZTE Axon 7 A2017U A2017 QD-Loader 9008 EDL


If your phone is booting, use  “adb reboot edl” command to boot into EDL/9008 mode. If not, use key combination, while pressing both Volume + and Volume – keys plug the USB cable in. Or try pressing both Volume keys and Power key while USB cable is plugged in, you will get the port eventually.

Good luck ..

Hi, using your guide and trying to flash with MiFlash the AndroidBrick_ZTE_A2017V1.0.0B07 it stops in this part (of log):

I’ve no idea of what is or how to fix it. I think it’s a bad partition but no idea of how to format or something. I only have access to edl. Could you please guide me?

Hi! I’ve tried all of the methods. It seems that the brick is the hardest. Can you advice?

Hi, I got bricked my axon 7 after i tried to root it with locked bootloader. So now when i try to turn it on, it shows a logo for 2 seconds (blinks with the red diod) and then dies.
It detects by PC only in DFU mode and can’t be seen in ADB devices command window.
I’m able to force Qualcomm drivers installation. In this case Qfil can see the device, but can’t flash it anyway (Download Fail:Sahara FailSahara Fail).
Miflash can’t see the device at all.
Please advise how to unbrick it.

Thank you for your reply!
Yes, I did a various combinations of keys pressing, holding, pressing one after another, the only mode (not forced) is DFU. Which does not allow to access CMD as well.
