[ZTE Axon 7 Guides, News, & Discussion] Oki:
WARNING, THIS GUIDE WILL WIPE ALL THE DATA IN YOUR DEVICE.

!!! Whatever you do, it is at your own risk !!!
​

This procedure will unbrick any Axon 7, returning it to stock. It fixes any kind of brick as long as your hardware is not damaged. You can't damage your hardware using software so if you have a healthy unit, you can recover it from any flashing "accident".

1. GET THE SOFTWARE

You need a Windows PC, Windows 10 is highly recommended. Do this:

01. Install MiFlash in your PC. It includes the Qualcomm Snapdragon SoC drivers, nonetheless you can always install the latest drivers.

02. Download the EDL flashable stock firmware package for your model:

A2017 (China): B14_MIFAVOR5 Android: 7.1.1

A2017G (Europe): B10_NOUGAT Android: 7.1.1

A2017U (Americas): B35_NOUGAT Android: 7.1.1

03. Unzip the firmware ZIP file to a folder in your hard drive.

2. ENTER EDL MODE

Option A: USING THE REBOOT COMMAND

If you still have access to your system but not to recovery or fastboot, then you just need to install any terminal app, open it and at the app's command prompt enter:

reboot edl

. You device will reboot into EDL mode. Now you can safely plug your Device to your computer. In your computer right click in the Windows Start Menu icon and select Device Manager. Under Ports (COM & LPT) your device should appear as Qualcomm HS-USB QDLoader 9008 using a virtual COM port. If you can see it, then you can continue to the flash section, step 14. Otherwise, if you do not see anything or a DFU device, then you'll need to explore the next option.

Option B: USING THE BUTTON COMBO

04. Press the VolUp and VolDn buttons in your device and keep them pressed.

05. Now press the power button until the red LED flashes, it does it really quick. Then release the buttons, starting by the power button.

06. Plug the device to your computer.

In your computer right click in the Windows Start Menu icon and select Device Manager. Under Ports (COM & LPT) your device should appear as Qualcomm HS-USB QDLoader 9008 using a virtual COM port. If you can see it, then you can continue to the flash section, step 14. Otherwise, if you do not see anything or a DFU device, then you need an EDL cable.

OPTION C: USING THE EDL CABLE

So, you need to get a Qualcomm EDL cable. With it you can recover from any situation. I use this one, DrakenFX uses this other model. There are cables out there not working properly so do not try to save 4 or 5 bucks and get yours from a reliable source. Alternatively you can solder your own by following this guide. If you are in an emergency (or your patience threshold is very low) and have a thin wire around you, then you can follow this DIY hack video.

Do you already have the EDL cable? then follow these steps:

07. Connect your bricked Axon 7 to your PC using the EDL cable.

08. Press the EDL cable button and keep it pressed.

09. Press the Power button of your bricked unit and keep it pressed too.

10. Wait 20 seconds.

11. Release the power button.

12. Wait 10 seconds.

13. Release the button of the EDL cable.

Voilà, your device is now in EDL mode. The device manager in your PC, under the ports category, should detect it as Qualcomm HS-USB QDLoader 9008. Now you can proceed to the flash section. If this procedure doesn't work, then your unit could have a hardware problem. Your only hope is to dissemble it by following this last resort guide.

3. FLASH FIRMWARE

14. Open MiFlash in your computer.

15. Click Browse button and select the folder you created in step 03 with the stock firmware files.

16. Click Refresh button and your device will appear listed as virtual COM port.

17. Click Flash button and wait for a few minutes until it finishes. Note that the bottom options are not applicable.

18. Now you have a stock Axon 7. Your data partition will still have garbage data, so you should enter recovery by pressing VolUp while rebooting your device with the power button. Release VolUp only when you reach Recovery. Using Recovery do a Factory Reset of your device.

That was the last step. Hopefully now you have a fully functional stock Axon 7.

By the way, this guide can also be used to return to stock any working device for selling or service!!!!

Cheers!!!!
