axon7tool: Flash and backup boot/recovery using EDL mode

Note: This is an inherently dangerous tool. I have made every effort to make it as safe as possible. But there is always a risk of bricking your device. You assume all responsibility for the consequences. Proceed with caution.
Warning: To avoid bricking your device, NEVER write both boot and recovery in one session. ALWAYS write one partition, test, then write the other. This is why the tool will only write one partition at a time.
Warning: There are versions of TWRP for the Axon 7 that are known to erase your IMEI when doing a restore. Do NOT do a TWRP restore unless your are SURE that you have a good version of TWRP!
This tool will allow you to:
Backup your boot and recovery partitions.
Flash a boot or recovery image (including the signed TWRP image).
See following posts for operating system specific setup instructions.
Once your setup is complete, enter EDL mode:
1. Power off phone.
2. Hold both volume buttons.
3. Plug phone into computer.
4. For G models, you must "adb reboot edl" (see other threads).
Usage:
axon7tool <mode> <partition(s)>
Note: The tool name will vary depending on your operating system.
<mode> is -r for read, -w for write.
For read mode, <partition> is one or more of gpt, boot, recovery. Files will be created as <partition>-backup.bin
For write mode, <partition> is boot or recovery. File will be read from <partition>.bin
Examples:
To backup everything on Linux:
./axon7tool-1.5-linux -r gpt boot recovery
To write recovery on Win64:
Place file as recovery.bin
axon7tool-1.5-win64 -w recovery
Links to axon7tool:
axon7tool-1.5-linux (main)
axon7tool-1.5-linux (alternate)
axon7tool-1.5-win64.exe (main)
axon7tool-1.5-win64.exe (alternate)
Link to signed TWRP removed.
FAQ:
Q: Can you provide a signed boot image with root?
A: No. I do not have the ZTE signing key, and tenfar's images are not current.
Q: Can I have the source code for the tool?
A: No.
Q: Can you provide the programmer?
A: No.
Q: Do you accept donations?
A: No, all work is provided freely for community use.

Setup instructions for Linux:
1. Ensure your login user is in the "plugdev" group.
$ id
You should see plugdev in the list. If not, add yourself to the group and logout/login to take effect.
2. Ensure your udev rules are setup.
Create a file eg. /etc/udev/rules.d/qcom.rules that contains:
Code:
SUBSYSTEM=="usb", ATTRS{idVendor}=="05c6", GROUP="plugdev"
SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", GROUP="plugdev"
3. All done!

Setup instructions for Win64:
1. Download zadig from http://zadig.akeo.ie/
2. Put device in EDL mode.
3. Run zadig. Select the WinUSB driver. If you have installed the Qualcomm EDL driver, you may need to tick "Edit" and find the device in the list.
4. All done!

Questions:
1) Does the backup of boot and recovery partitions work like backing up through TWRP (if the recovery is already flashed to TWRP)
2) The signed TWRP image is by... ZTE?

1- No this doesn't work like backing up with TWRP, This tool is more powerful than Custom Recovery (TWRP), and you should be very careful on how to use it.
Like @tennear mention about try first by using -r (read) then just flash the sign TWRP.
I personally recommend just flash TWRP and DON'T mess with Boot image.
2- the Sign TWRP is not provided by ZTE, ZTE will NEVER release a Custom Recovery for us users.

1. The tool writes the raw partitions to your PC. Whatever you have in the partition is written out, whether it is stock recovery or TWRP or whatever.
2. The signed TWRP image is copied from the zip that tenfar provided in his post. I did not create it, and I cannot create signed images.

Forgive me my noobiness, but here’s a step-by-step-instruction list. Am I thinking right? I want to minimise the risk when I try your tool tomorrow.
Step 1: Enable Developer options in phone by tapping the build number
Step 2: Enable OEM Unlock in phone (is this needed?)
Step 3: Enable debugging (for adb)
Step 4: Connect phone to PC
Step 5: Download Zadig
Step 6: Install Zadig
Step 7: Open command in the folder in which you downloaded adb.exe (and the rest of the files that come with it) (Richt click while holding shift to get the option to open CMD in a folder)
Step 8: Enter the command “Adb Devices” to reassure your device is detected
Step 9: Enter the command “Adb reboot edl” to reboot the phone to EDL mode
Step 10: After phone has rebooted to EDL mode, run Zadig, select WInUSB driver and install it for your device
Step 11: Rename “axon7tool-1.5-win64.exe” to “axon7tool.exe”
Step 12: Download “axon7-2017u-twrp-signed.img” to the folder where axon7tool.exe is located
Step 13: Open command in the folder in which you have downloaded axon7tool-1.5-win64.exe (renamed to axon7tool.exe)
Step 14: Enter command “axon7tool -r gpt”.
Step 15: Enter command “axon7tool -r boot”
Step 16: Enter command “axon7tool -r recovery”
Step 17: Verify if the tool has created “gpt-backup.bin”, “boot-backup.bin”, “recovery-backup.bin”.
Step 18 (unsure): rename “axon7-2017u-twrp-signed.img” to “recovery.bin” ?
Step 19: enter “axon7tool -w recovery recovery.bin
Step 20: Wait for the command to finish
Step 21: Place the .zip file for Z.A.D. Mix7 or CM13 on your SD card via your PC or Axon 7. Also download Gapps.zip of your choice and place on SD card.
Step 22: Boot your Axon 7 to TWRP Recovery by holding the power button simultaneously with volume down (or is it volume up?)
Step 23: Perform a full wipe of Dalvik, Cache and Data in TWRP
Step 24: Flash the .zip of your custom ROM of choice in TWRP
Step 25: Flash the .zip of your Google Apps of choice in TWRP
Step 26: Perform a full wipe of Dalvik, Cache and Data in TWRP
Step 27: Reboot your phone, enjoy the custom ROM of your choice.
Is this the correct procedure?
I’m a bit unsure of step 18. Am I doing it right? Or do you need to unzip that .img somehow to find a recovery.bin file? Or do you need to get that file from somewhere else? Or do you need to rename “axon7-2017u-twrp-signed.zip” to “recovery.img”?
For Z.A.D. MIX7, I suppose you still need to flash a SuperSU version seperately? I heard in CM it's baked-in.
Thanks for the help.

@Controllerboy close, but not quite. I'll attempt to provide detailed feedback on your step by step list tomorrow. Time for sleep now.

The tool is "one shot". You can read any combination of gpt, boot, and recovery in one session, then the tool will restart the phone.

Yes, this is correct. Writing boot or recovery takes about 30 seconds. Then the tool will reboot your phone. Be sure to hold the Vol+Up button to reboot into recovery.

You cannot unzip an img file.
The TWRP image provided is just as tenfar provided for 2017u users. You only need to rename it to recovery.img for using the tool.
If someone has the 2017g TWRP file, I can upload and link it. The links in the tenfar post have been removed.

Folks who are able to use this new tool/method successfully, please report back with your variant. I can't test this myself, so I'm relying on some verification before I update the newbie guide to point here instead of tenfar's thread (which is outdated and no longer updated as tenfar is now inactive).

That is correct.
d-h.st seems to be down for the past few days. I guess it will come back at some point, and you can download the zip file to extract the recovery image. Or maybe someone else has a copy of it...

As far as u know TWRP is the same for every A7, sign or not.

Unpacking the TWRP image for A2017U, it says:
ro.product.model=A2017U
So this recovery seems to be specific to A2017U.
But unpacking the TWRP image for A2017 (China), it says:
ro.product.model=ZTE A2017U
Hmm, different but still A2017U.
I don't have the TWRP image for A2017G (yet), so I can't tell what it says. But given the above, and that the G and U models are almost identical, I am thinking the A2017U image will run on all devices.

No. I have not built the tool on Mac yet. I will try to do that soon.

I wouldnt say I was a newbie but how do you get the file to run. Even with Antivrus off, the computer just wont run it.
Thank you for the time and support.

The .exe file isn't meant to be ran on it's own. Double-clicking it won't do a thing. You need to use cmd (command) to execute commands to the file. If you look at my post on the first page of this thread, you'll get an idea of how the process works. But please don't follow my post as of now, since it's not detailed nor 100% correct yet.
It's my intention to try my luck tomorrow and I'll post a detailed and 100% correct step-by-step-process.

Excuse me for my ignorance, but how does this tool differ from tenfars tool? Beside not being able to write two partitions at the same time that is.

No need TWRP or O.F for rooting.
Root***:
1. Find or redownload the TGZ file for your current ROM or other rom.
2. Browse inside the zip file and find boot.img under the images folder
3. Copy this file to a temporary location in your PC first, and then transfer it to your phone
4. Install the desired version of Magisk app
5. Run the app and choose Install under Magisk
6. Choose Select and Patch a File, then select the boot.img that was transferred earlier
7. A process will run and create a new .img file in the same folder where the original one was
8. Transfer the new file to your PC in the same directory where fastboot.exe is located
9. Open a command prompt window in that same directory
10. Reboot your phone to fastboot mode and connect to PC, USB2.0 port. Check for connection by running command fastboot devices.
11. Run the command fastboot flash boot_ab magiskXXXX.img
Once it's completed, run command fastboot reboot and the phone should boot and be rooted.
***
This is the most common current method.
On some devices, vbmeta,disable-verity are required.

Writing 'boot_ab' FAILED (remote: 'This partition doesn't exist')
fastboot: error: Command failed
Can you help with that?
Do I have to open a new thread? I am new here. I just see your valuable post and seems the same scenario as OP except for the model number.
Also can you help me to provide these On some devices, vbmeta,disable-verity are required. if needed.

Question Redmi Note 10 5G can't install fastboot with miflash

Hey all.
I tried getting the Fastboot rom onto my phone but nothing works. I keep getting errors like **FAILED (Error reading sparse file)**
At this point I don't know what to do, I might go to Xiaomi to show them it and possibly get them to do something about it.
EDIT!!!:
I fixed it, changed folder name to x and worked. Thanks to NOSS8 for trying to help

Me for writing this guide
Please hit thanks if this method worked and bye!
EDIT:
Edit 1: Added TWRP 3.2.3.0 by Yashraj22

You can try flashing this rom: here
But i still haven't tested the rom yet.

That worked even with the newer version of the stock ROM still installed (2017-something).
What I did is I dumped the devinfo partition with https://github.com/bkerler/edl, edited it in the hex editor, flashed it back and then TWRP installed, booted and works.
LineageOS 17.1 works as well (except some minor things, like the FM Radio)
Thank you very much.

God it works great. Only the twrp flash step is the most confusing. I don't quite get it yet, but there's a way around it anyway. Root with kingo root then use oppo tools to flash twrp

can anyone help me with step 2
how to enter com number with this cammand dump_devinfo.bat
