I kinda wish we'd scrap all of the unlock and recover methods and just have all of the devs making threads to just resort to a Wugfresh tool like this. Any way to make unlock/locking/restoring/recovering hands off and safe would really help a lot of us out.

We could implement a bunch of backing up, signature verifications, and delays before steps occur so it's more foolproof and not have to rely on timing of key combinations and picking which file to use for whatever.

I'm planning to release a new version soon with support for adb backups in TWRP, restore to stock using TWRP, and an option to restore to B29 in edl for those who don't want B15.

Stay tuned :)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] wyrethewolf:
This does not seem to be working for me. When attempting to unlock the bootloader the application puts my phone into fastboot mode, and closes. ZTE Axon 7 factory nougat upgrade (B15). Have downloaded the MiFlash application as requested, but option 4 just places my phone into fastboot mode and then the application just exits.

Phone will now only boot to Team Win asking for a password (I didnt have a password set). Looks like my phone may be dead.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bkores:
[MENTION=1130079]wyrethewolf[/MENTION] The issue has been fixed. I'll upload the new version as soon as possible. For the time being if you are in TWRP you should be able to boot to system by pressing cancel on the decryption screen and then going to Reboot<System.

It was a tiny typo in the fastboot check which screwed up the entire script lol.

Thank you, I will give this a try. Thank you for checking in on this!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bkores:
New version is up! This should *hopefully* fix the application closing issue with the bootloader unlock option.

If you already have the toolkit, no need to download this one. It'll automatically be downloaded when you launch the toolkit.

Also if you get any errors of failing to close adb.exe during installation just press ignore. I've already fixed this for future releases.

It seems that there are some issues with the old build of wget (1.11.4) that is included in the package.

i replaced the wget folder with the single executable from eternallybored, 64-bit build 1.19.1 (only the exe is required) and voila! All worked well

https://eternallybored.org/misc/wget/

It may be an idea to update your wget to the newer revision for users not in the US.

Last post of the night - now I have the toolkit up and running:

1. I have an A2017 (Chinese) with 7.1.1 ZTE_A2017V1.1.0B11. Is it OK to perform a bootloader unlock on this build, or do I have to roll it back?

2. In the Restore instructions (bootloader unlock) it suggests flashing the files in C:\Axon7Development\Axon7Toolkit\miflash\B13 or B15 or B29. (depending on model) All folders are empty. Should these be auto populated, or do we have to manually download the relevant files?

Thanks!

Mike
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bkores:
1) Yes the bootloader unlock will work on any build

2)The toolkit will download the restore package at the time you use the restore stock option. If I provided all the packages the toolkit would be like 6 GB lol.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] mwarner:
Personally I had no luck getting a bootloader unlock on my 7.1.1 A2017 (Chinese) device. I had to roll back to Marshmallow, unlock the bootloader on that ROM (which has Fastboot installed), get an OTA back to 7.1.1 and then flash TWRP via EDL mode with axon7tool.

Whatever I did I could not get Fastboot working on a Nougat ROM, hence the need to roll back.

I went back to b10 from the German site, then was able to unlock my bootloader (it's simple and says it will reboot in 5 seconds if nothing is pressed).

I could keep my bootloader unlocked while updating to 7.0 (SD) 7.1 b01 (SD) 7.1 b02 (OTA)

However, whatever I do with the Axon7tool fastboot is never recognized, nor is a command prompt "fastboot devices".

I've gotten all of the drivers from the Axon7tool and the device, but nothing (dicoverd fine when booted into Android or in EDL). Is it actually a driver problem, or should I just adb flash TWRP onto it and go from there? Any suggestions?

Now I need some help. After unlocking and flashing TWRP I ended up at rebooting to boot screen. Next thing I did was the stupidest ever. I thought I had a working TWRP in an old folder, so I flashed it. Turned out to be a Marshmallow stock recovery that I used previously to restore to stock before 7.0 turned up. Only things left now are an old stock recovery that I can boot in, booting to sytem ends up in the boot logo.

Any great ideas??

Update: Flashed the 7.0 update from ztemobile.de through old recovery from SD, it is booting now but update to B02 is not working, I am stuck on B01 with unlocked bootloader and stock recovery. Trying to flash something from SD card is not allowed. Would it be possible to just use the lock bootloader option from axon7toolkit or will that brick my device ??? I did flash the unlock file with Miflash so fastboot is working. No backup this time

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
You mean that axon7tool never works? You need to get to EDL (with the phone completely off, hold both volume buttons [NOT power, only volume] and plug the USB on the phone [previously connected to the PC]). Then go to Device Manager and see if the driver is Qualcomm HS-USB QDLoader 9008, in that case right click, uninstall, delete driver software too. Hold all 3 buttons at the same time until the LED turns on or you see that device manager refreshes. Now you should see QUSB_BULK as an unknown device. if windows attempts to install a driver, cancel it. Download Zadig and install WinUSB driver. Now QUSB_BULK should appear under USB devices or whatever (at the bottom of the list, in English). Hold the 3 buttons again until the led turns on, and you're good to go: open CMD, and use axon7tool
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] ramnkc:
Mind to share out how you did the bootloader unlock step by step?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Grogros4:
Sure, here are the steps :

1) Check all your drivers using the 1 in the toolkit

2) Start the bootloader unlock procedure (make sure ADB / OEM unlock is toogled)

3) I had someissues with Miflash not recognizing my device : I went to the driver manager in Windows and delete the driver under COM and then unplug / plug my device to the PC several tome. After 5 minutes Miflash detected my device as COM 3

4) I hit flash and Miflash did its job smoothly

5) When I exited EDL mode my device rebooted and then I saw the screen asking for a passOrd. The toolkit wasn't able to detect my device as ADB.

6) I powered my phone off and turn it on FTM ( power + volume down )

7) Then the toolkit detected my phone and he applied the bootloader unlock and erase all my data. My device booted normally

I hope it helps, if you have any questions PM but keep in mind I'm not a developer​ ;)

TWRP, Xposed, and installing a new ROM

Hi, I used to root and play with ROMs on my old Samsung's..Note 3, S5, S4, etc. But haven't been playing with my ZTE AXON 7 until this toolkit came out. I used it to unlock the bootloader, and root the phone. Now I am trying to install a custom Rom, and then would like to install Xposed. I have tried this using the Toolkit, but whenever I select a Zip file, the program closes on my PC and nothing happens. I also tried to figure out how to boot into TWRP, but haven't figured how to do that either. When I get it into recovery mode, it is just in the stock recovery, and it won't let me select a zip file. Can anyone help me with this?

Thanks in advance! :)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] piet8stevens:
TWRP

Are you sure you have installed twrp? If you only have the recovery but no twrp, this is what you can do:

Once you have fastboot and an unlocked bootloader, you can do it manually yourself as follows:

a. Download twrp from here: https://build.nethunter.com/twrp/zte/twrp-3.0.4-1-ailsa_ii.img

b. Connect your phone to your PC and reboot to bootloader: adb reboot bootloader

c. check that you are ok: 'fastboot devices' should show your device.

d. Flash your downloaded twrp: fastboot flash recovery twrp-03.0.4-1-ailsa_ii.img

Now, when you boot to recovery, you should be in twrp. From there, you can wipe your phone and install the .zip from a custom rom from within twrp.

Good luck,

Piet
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] ColorfulPoland:
I handled the problem and unlocked the bootloader. Now I have a problem with rooting. I tried three options, I installed by TWRP two different zips with SuperSU, TWRP showed that everything ok, installed, but when the phone turned on, there was no trace of SuperSU and no root. The third way was axon7toolkit, he also showed that everything is ok, but after restart the system was still the same. It's a total of 14 hours, but I do not give up. But without your help, I may not be able to succeed. Please help.

In addition, a strange problem appeared. Suddenly, during installation of SuperSU zip by TWRP and axon7toolkit rooting the phone turns off. Previously there was no crashing.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] piet8stevens:
I successfully unlocked the bootloader but have a problem now. I am on A2017G B08, Android 6.0.1. Have not modified system. Installed twrp. I wanted to upgrade to Nougat, which as per the German web-site requires me to first update to B10. I received an OTA update to B10 but it refused to install with a message my phone is a different version or something like that. I tried to return to stock recovery, in the process eliminating twrp. Still no success. I then used your toolkit to relock the bootloader and now, after the startup graphics, the phone requests a password to start android. Any ideas? adb devices shows the device but as being offline. I can get to factory check mode and from there boot into edl by issuing adb reboot edl. But then I am stuck. When the phone is in edl mode, it shows up as Qualcomm HS-USB QDLoader 9008 on a com port. When I try to use miflash to unlock the bootloader again, it says "Receiving hello packet" and then "Missed hello packet, try to recover" and then nothing happens.

Thank you, Piet
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] gaijin1%:
That request for a password is a built in feature of Android when it detects suspicious activity like flashing back and forth. There is nothing you can do about it, except wipe your data and factory reset. This is why we make backups, but that doesn't really help when going back to stock with a locked bootloader. Recently did it myself as no custom ROMs are currently supporting Daydream properly. Huge pain in the ass for a security feature I didn't ask for, and no option to disable it.
