I am trying to save a backup using TWRP before unlocking the bootloader. I have followed steps A.0 to A.22 but step 23 fails. When I try to enter into recovery, the phone enters into EDL mode. It happens both when trying the key combination or using "adb reboot recovery". I have an A2017U with the latest OTA update to date (B29). I am flashing the latest TWRP to date (3.0.3-0) and the custom one linked in the OP post. Both fail.

EDIT: I have found my issue. I wasn't flashing tenfar's signed version of TWRP 3.0.2-2 (http://d-h.st/dgWW). When using it then TWRP becomes persistent. The problem was a mismatch between the signature of the bootloader and Recovery images. Now I am able to do a TWRP backup of my system and I am now free for playing around with it.

NOTE: It would be very convenient to add a note in the OP guide reminding to disable the antivirus software, otherwise axon7tool wont work properly.

Hi All,

I have a quick question as I'm having problem booting into edl mode. After following step 14 my device reboots and appears it is off without the red notification light on. I was unable to recognize the device as stated in step 15 or continue to carry on with step 16, instead I received an error message "error: failure to connect". I can no longer restart my device and was only able to boot up again by going into recovery mode( holding down the volume up and power button"). I tried again and it is the same result. Please help, thanks!
[ZTE Axon 7 Guides, News, & Discussion] Oki:
Assuming you are using Windows, go to the device manager and ensure that when you plug your device in edl mode, it is identified in the device manager as QUSB_BULK without the warning signal.

If you have the QUSB_BULK with a warning icon then you need to install the Qualcomm usb driver.

If you obtain the Qualcomm HS-USB QDloader 9008 device instead of QUSB_BULK, then you have to use the zadig tool in windows. go to Options and activate List all devices. Then select QUSB_BULK in the drop down control at the top and WinUSB in the lower control. Then click on the button to replace the driver. After this, QUSB_BULK should appear in the Device manager and you should be able to execute axon7tool.

By the way, do not forget to deactivate the antivirus, otherwise axon7tool won't be able to transfer data.
[ZTE Axon 7 Guides, News, & Discussion] projectseahorse:
Hi Oki,

Thanks for the tip, it helped a lot! I followed the instruction and was able to reach until step 23 where I needed to verify successful installation of TWRP by holding the volume up and the power button down sententiously for a couple of seconds. When I do this, it does not boot into recovery, it just turns off the phone instead of going into recovery menu. Everything else works fine. Does this mean that the installation was unsuccessful? What should I do? Thank you so much for the help!

PS: I think I should also mention that my device is not unlocked, could that be the cause? I'm currently on build B29 and all the unlock guides I found uses build B20 so I 'm not too sure how to unlock a build B29, any tips on that issue will also be greatly appreciate it! Many thanks and thank you for your kind help!
[ZTE Axon 7 Guides, News, & Discussion] Oki:
I am also in B29, with an A2017U. I found the same issue as you. But actually the system was not off, it was actually switching to edl mode because the recovery partition has a signature that doesn't match with the signature of the bootloader. So, the only way to do it is by flashing a signed TWRP. So the only one I have found is TWRP 3.0.2-2-signed by tenfar. just rename to recovery.bin and flash it with axon7tool +w recovery. That recovery will allow you to backup your Data partition before you unlock the boot loader.

Consider also doing a backup of the internal sdcard before unlocking the bootloader since unlocking the bootloader will corrupt all the data in the sdcard.

Be careful of not modifying the system partition, otherwise you will need to place again the stock recovery and flash the signed OTA ZIP files to recover the phone.

Hi Oki,

Thank you so much, it worked! Now I'm able to access TWRP menu. I just have a couple more noob questions. can i directly install root via twrp without having to unlock BL first? If I can, can you kindly direct me to the right guide? Thank you so much!
[ZTE Axon 7 Guides, News, & Discussion] wimstefan:
Is there a similar description to achieve the same under Linux?
[ZTE Axon 7 Guides, News, & Discussion] Oki:
I want to try the promised root without unlocking the bootloader proposed here. The trick is to flash the boot.bin too. I can't tell you much more since I haven't tried it yet. Probably it would require to downgrade to B27. It is not difficult, but it takes time.
[ZTE Axon 7 Guides, News, & Discussion] projectseahorse:
Hi Oki,

Sounds like I'd be better off unlocking my BL first? I'm looking at this guide here and was wondering if I can unlock my B29 Axon 7 with the guide since it is intended for B20 or 27 software but I'm on B29. I'm super noob, any help would greatly appreciate it! Thank you so much!
[ZTE Axon 7 Guides, News, & Discussion] Oki:
I will try tenfar's method before unlocking the bootloader. Unlocking the bootloader (BL) is not reversible yet so it is not possible to return to a full stock configuration. I have always had unlocked BL and custom ROMs since 2002 and this is the first time I am trying to make things harder and try to get everything without unlocking the BL.

However, if you want to unlock the BL then the DrakenFX guide, the one you mention, is one of the fastest and very straightforward. However the method proposed by jcadduono in his AXON7 TWRP official thread is also an option. The required downloads are huge, but they will be very handy in case something goes wrong. I used them to return to fully functional phone after playing around with TWRP without patching also the boot partition.
[ZTE Axon 7 Guides, News, & Discussion] lafester:
You can relock and ota has nothing to do with unlock status.
[ZTE Axon 7 Guides, News, & Discussion] gregou:
Can someone post a guide on how to Re-lock bootloader and go back to stock ? (version A2017G)

I tried this and it didn't work (got stuck on DFU mode but i managed to reboot in TWRP somehow so i'm still unlock bootloader but at least, my phone still works) :

So i was unlocked with CM13 but not fully satisfied so i downloaded bootstack.zip and stocksystem.zip from B08 firmware made by DrakenFX. I flash bootstack, stocksystem, then i reboot my phone in bootloader mode (fastboot) and try : "fastboot oem lock" but the phone didn't reboot and get stuck in DFU mode directly...

Any idea ?

Quick question,

For the twrp 3.0.2 does it have a " install zip from sd card" option? I'm using the unlock kit mentioned in jcadduono's thread and following the instructions. I'm at the steps where I'm suppose to install zip files from the external SD drive. The instruction says to use the option "install zip from sd card" but I was unable to find this particular option. Instead, I tried install => install from zip and try to select the zip. after selecting the zip it says swipe to confirm flash and after I swiped, it started to run but then it says error. Can anyone offer any insight into any possible resolution for this problem? Thanks so much!

Yes there is a Linux variant of the axon7tool. Search for the thread of the guy who made it. There is a link posted also to the Linux variant. It is way more convenient to use considering you don't need to hassle with drivers as in windows.

After flashing the recovery trough EDL mode, I hold both Vol Up + Power Button and it shows the ZTE logo for a second and turns the screen off but with a red notification led. So my phone stays with a black screen and a red notification led, when I try to enter the recovery. Because my device was not able to be found in EDL, I used Zadiq and it did the job succesfully. Did anyone find a solution for that? I cannot boot into TWRP. My device: A2017G B03 Thanks in advance

Edit: I tried to restore my recovery-backup. I renamed recovery-backup.bin to recovery.img and executed the command axon7tool -w recovery in edl but the same result. Black screen with red led. Help would be much appreciated.

Edit: Solved with renaming TWRP from recovery.img to recovery.bin

My phone is the A2017U version on B27 fw, I have a few questions.

I already followed the root without unlocking bootloader guide, so I have TWRP installed (but not SuperSU, that won't install, so I have Superuser installed instead) and it is rooted.

1. Can I skip all the steps in A and start with the steps in B?

2. Do I need a different aboot.img for the A2017U model?

3. Is there a CM13 rom for the A2017U model or can I just install the A2017G rom?

Thanks.

next root left .

what to do?
[ZTE Axon 7 Guides, News, & Discussion] ValVK:
I will get my Axon 7 2017G and will unlock BL, set up TWRP and root it.

Just to clarify the full process and not to do something wrong:

1.Unlock BL as described in OP.

2.Setup TWRP. Since, here is official TWRP 3.0.3.0, can i do TWRP 3.0.3.0 it as in official TWRP thread http://xdaforums.com/axon-7/development/recovery-official-twrp-zte-axon-7-t3515715,

flash TWRP with fastboot? Or i must do it as described in OP here? If it must be as in OP, can (must) i use that 3.0.3.0 file for TWRP?

What is with no-verity-opt-encrypt-5.0.zip (latest version)? Must i flash it after install TWRP?

3.Obtain root with flashable SuperSU from TWRP. Must i use only ver.2.65, or i can flash latest version of SuperSU .zip?

Thanks all in advance, i just want to do it right from first try...:)
[ZTE Axon 7 Guides, News, & Discussion] vavida:
I guess you just need to download supersu v2.65 and flash it with twrp.

Thanks OP!

Did it on my Axon7 A2017G. Didn't install CyanogenMod13 though, just finished installing TWRP, unlocking the Bootloader, then flashed SuperSU 2.65 through TWRP to get root. I want to stay stock. Everything work well so far!
[ZTE Axon 7 Guides, News, & Discussion] Dust2Dust:
Just follow the correct order from OP:

1. Flash TWRP with the provided files

2. Reboot to recovery

3. Unlock bootloader with the correct steps, maake one change though:

Correct steps are:

6) Type "adb push aboot.img /sdcard/" and hit enter

7) Type "adb push fastboot_unlock.img /sdcard/" and hit enter

after that the OP is fully correct.

Final step: flash super su 2.65 from chainfires website

Final step 2: Flash new twrp 3.0.3.0
[ZTE Axon 7 Guides, News, & Discussion] mariusfl0rian:
I managed to do it correctly, but I wanted to help the others a little bit because in The OP there was no space between the .img and /sd. Now the OP corrected it and there is a space. Thanks to him.

That question "is it possible to root without unlocking bootloader ?" interest me as well. Is it possible just to install TWRP as in guide in OP,

A2017G has no EDL mode. So why you descibe it in the turtorial ?
[ZTE Axon 7 Guides, News, & Discussion] Controllerboy:
Sorry man, but this is simply untrue. A2017G boots to: System, Recovery, Bootloader, FTM, EDL and DFU.

System mode accessible through normal boot. Recovery: power + volume up or "adb reboot recovery". Bootloader: via recovery or "adb reboot bootloader". FTM: power + volume down. EDL: "adb reboot edl". DFU: power + volume up + volume down or volume up + volume down while plugging in the USB cable.

A2017 and A2017U devices seem to lack the DFU mode, OR they never "get stuck in it" like some A2017G users
[ZTE Axon 7 Guides, News, & Discussion] bungie240:
This is strange...when you boot the phone hold the volume up and power and hold for a further 3 seconds after the ZTE logo appears then release both buttons, can't see why it won't boot to custom recovery if all the other steps worked!

I had a similar issue earlier today where the ZTE logo would appear then go off after 1 second and then red light, this was self inflected though as I managed to install custom recovery then do a back (step 25) then i tried to flash supersu to grant root which then gave me the same symptoms your phone is having.

I was able to restore my back-up and only then was my phone recognised as a device in the command window and was then able to unlock bootloader.
[ZTE Axon 7 Guides, News, & Discussion] tuiyaan:
I unlocked BL in B08

Edl mode exist in EU phone

But strange there is no led indication in edl

Here is what I did

Disabled antivirus

Adb reboot edl

Phone screen is off no led

Connect to PC and check in device manager

Qualcomm driver will appear under ports

Remove drivers and phone should appear as unknown drivers

Restarted phone and PC (I do it out of habit:))

Again hit adb reboot edl

Open zdiag tool and select winusb and install drivers

Close zdaig tool and open device manager under USB u should able to find Qusb bulk

Again restart PC and phone

Hit adb reboot edl

just check in device manager Qusb bulk should appear under usb

Now execute axon7tool command

Now axon7tool will execute without getting hanged or auto close

Just have patience and try different possibilities

I tried 20+times before axon7tool command worked

Edl will not have any led indication

Phone goes to edl mode but drivers is D problem

Keep trying hope this helps

Flashing TWRP works without any problem.

but now, i got the following problem, when i make this steps

8) adb shell dd if=/dev/block/bootdevice/by-name/fbop of=/sdcard/fbop_lock.img
9) adb shell dd if=/dev/block/bootdevice/by-name/aboot of=/sdcard/aboot_lock.img

i always get "permission denied".

So i tried it in TWRP with Sideload Windows (Win7 x64) can't find any Driver for A2017U, so i installed Universal ADB Driver from Kosh

but, when i try the Steps (8 & 9) it says "error: closed"
