I assume you will have to downgrade aboot to get fastboot working again. This seems to be the same problem with the G variant using V1.2.0B02. On this version it is neccessary to downgrade aboot to version V1.2.0B01 as ZTE stripped important parts from it to prevent users from having fastboot. You might have to flash the fadtboot image as well.

Need a working Method For Converting Chinese Axon7 to US Axon7

I Have rooted and Unlocked Bootloader with Twrp Recovery.

Currently on B13 chinese Marshmallow

Please can i get proper method and working link :)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] deepasadish:
i am currently on 6.0.1 B29, locked bootloader, fully stock.

i am a little confused by the instructions in the OP.

if i simply flash:

<quote>

B19-NOUGAT_TWRP (Nougat 7.1.1)

This will install TWRP 3.0.4-1 and unlock fastboot operations while restoring B19-NOUGAT boot stack.

</quote>

will it take me to all required stuff for lineage OS (with unlocked bootloader)? i.e., after flashing that, i simply flash lineage via twrp. thanks.

edit - i guess to answer my own question, "unlock fastboot operations" is NOT the same as "unlock bootloader"

so, i have to first

<quote>

FASTBOOT_UNLOCK

This will unlock all fastboot operations, including OEM unlock and fastboot boot/flash.

WARNING: Unlocking your bootloader will erase all userdata on the device! Your device will be completely reset to factory defaults!

</quote>

flash that and then flash the B19-NOUGAT_TWRP and then lineage.

Can someone confirm. thanks.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Yanyan80:
Recently I had problem with my phone and I may tried something bad and brick my 2017U pretty hard. No fast boot, no TWRP, only red light. Luckily enough, I am still able to enter to the EDL mode. I've tried Miflash so many times with multiple computers and cables, all come with the same error message, "[4.51 COM4]:cannot receive hello packet,MiFlash is trying to reset status!" I've tried the older version of MiFlash still no luck. It will be greatly appreciated if someone can help me out. Thanks.

---------update-----------

Ha, I finally figured it out. when the error appears doesn't matter what port or cable you are using. It's the phone does not ack on the handshake. You will have to restart the phone and put back to the EDL mode. For the file, it needs to be unzipped. Select the unzip-ed folder, and flash. If error occur, you will have to restart the phone and put to EDL mode again, eventually it will establish the communication and then start flashing. My phone is back to life now.

You can also hold all 3 keys until the LED flashes, and then wait 3 seconds. That will reset EDL, which is kinda faster

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JeromeLeung:
Flash the B19 TWRP package. B25 doesn't let you into bootloader
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] zolo111:
So just flash it through bootloader "flash from sd" correct? Or Axon7 tools?

-"fastboot oem unlock"

-Install Universal Bootloader & modem.

-Then install LOS & gapps

Is this correct?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JeromeLeung:
Sorry I should have been more specific. Use miflash to flash the B19 TWRP package from the op. That should allow you to go into bootloader to run "fastboot OEM unlock" in terminal. After that just follow the directions to flash the ROM of your choice using TWRP

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JeromeLeung:
Pretty much all that. You can flash the B19 TWRP package instead of the full instead. It's a smaller download. Otherwise follow [MENTION=2586579]mwiley[/MENTION]'s guide here and you should be golden.

Maybe you can try the Axon7toolkit:

https://xdaforums.com/axon-7/development/tool-axon7toolkit-t3573108

Since your phone already has bootloader unlocked (custom ROM), you should first try to get TWRP recovery (latest 3.1.1-0 version https://eu.dl.twrp.me/ailsa_ii/ ).

Once TWRP is back, you are safe to flash stock or other custom ROM.

Hi,

I have A2017 (China) version with unlocked bootloader. And, I have downloaded B19-NOUGAT_FULL (Nougat 7.1.1) to flash via EDL mode. However, I am worried about the network because I saw some comments where people are saying they are not able to network after converting A2017 to A2017U.

Edit: I finally got it booted enough to turn on oem unlocking. It can see the file now, but it won't use it for some reason. Seems like I'll need to RMA it. :(

Edit 2: Finally got the stock recovery to flash the file and it still boot looped while it was doing that. Off to RMA it goes.

Bump here. Every attempted application of miflash ends me on this same problem. Inspecting the files, I see no flash_all or any other batch files in any of those listed here. Is there somewhere else these reside? I downloaded the miflash version listed here -- 2016.08.30.0

the batch file complaint maps to the radio button on the bottom of miflash, "clean all", "save user data", "clean all and lock" ask for different batch files but none are present.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jdaggar:
UPDATE: it looks like MiFlash cannot detect my phone in EDL mode. It detects it fine when it's running normally, but it can never find it after it boots into EDL. I've cleaned out all my drivers, re-installed the Qualcomm ones from the OP's link, but no love. I'll keep trying; I might try a clean VM or even install win7 on a random partition.

UPDATE UPDATE: I got it working. I think it was something related to previous use of Zadig that had the drivers in a twist.

Anyway, what I did:

1)While my phone was connected to my PC, I launched it into EDL mode as usual.

2)I went into my PC's device manager, found the phone where it was listed there. This should have been an indicator of trouble-- it was listed under generic USB devices instead of under Ports. This is about how it should look:

[IMG="Device Manager"]http://i.imgur.com/xoZD7q4.png[/IMG]

3) I right-clicked on what the phone -was- showing up as (again, it wasn't that above) and kept uninstalling it and clicking the checkbox to remove the drivers as well. Eventually, it worked.

I hope that helps someone.

For anyone having issues with MiFlash not detecting EDL mode, here's a pro tip.

Yesterday, I received my repaired phone back from ZTE so I immediately started to unlock again. Installed the driver, put device in EDL (both vol buttons + power). It continually showed up in device manager as android diagnotics device COM3. I forced the QDLoader driver install over it. MiFlash would still not detect, and I even tried another computer. Long story short, the device was not properly entering EDL mode using the button combination, even though it appeared to be.

Super easy way to make sure its in EDL:

1) Plug phone into computer

2) use the connect to PC software option for the usb connection on phone (or just enable adb debugging in developer options)

3) use the following command in ADB: adb reboot edl

4) Device will reboot and enter EDL without fail every time

5) ???

6) Profit

Flash an older build with MiFlash. The newer ones seem to have bootloaders that won't let you in if you're unlocked or something. Once you find a build that lets you into bootloader flash TWRP before upgrading to whatever the most recent build is for your model.

After installing twrp on my chinese axon 7 latest B16 I rebooted accidentally and now my phone gets stuck on the the ZTE logo.

I cant enter recovery as when I press volume up + power, it reboots a couple of times with the zte logo and nothing else.

Also when entering EDL mode the only thing my PC is showing in device manager is "Handset Diagnostic Interface(DFU) (COM6)". Before it was showing as "Qualcomm HS-USB QDLoader 9008" but no more, even after multiple reboots and installing the qualcomm drivers again.

Before when running "adb devices" in the CLI I would see my device but now nothing. and running adb reboot edl shows error: no devices/emulators found.

Also tried MiFlash but when I hit refresh I dont even see COM in the list, its just blank.
