Yes, did it the same way. Worked in the end, but should be less trouble with the edl cable next time. But if development should stop here, I'll drop this phone. There is new hardware that is pretty interesting.

the procedure is the same, except for the fastboot unlock and firmwares

search for those in other threads

but beyond that, why do you need this? what's your issue?

Big iusse ?

I was on LOS 15, I went back to LOS 14 by TWRP backup , but after reboot, I couldn't enter pasword, so I tried to reset it by google manager, unfortunately I mistaknly did formatting instead of reset , so my phone stuck in loop , I couldn't enter recovery again, also when I enter EDL mode, the windows didn't show my phone as Qualcomm 9004 port.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bornlivedie:
does it show as DFU? post a picture

can you enter FTM? it's volume down + power

can you enter fastboot?

does the led blink a few times when you try to enter recovery?

if no to everything, then you will need to disassemble the phone or try your luck with a deep flash cable (never worked for me, worked for some)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] am2006:
…up
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bornlivedie:
FTM mode is factory test mode, the screen says FTM inside a white rectangle. It should be accessed when pressing down vol down + power

when you boot the phone, do yo see the ZTE logo then the bootloader unlock warning? if you see the warning, press vol down and chose fastboot, if not, try vol up and power and tell me what happens
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] am2006:
"ZTE powered by android" logo only what is shown, after that screen go black and LED blink 3 times, then shutdown, in both case vol up/down and power.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bornlivedie:

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bornlivedie:
Can you boot into recovery? if not, can you flash recovery?

In DFU or fastboot (bootloader) try with Axon7_EDL_Tool

Try to enter FFBM and try with Axon7_EDL_Tool

Any of those things should work. Maybe you will have more luck with FFBM and A7 EDL Tool

Hi, could I get some help, please? I have A2017U on B35 N and having issues. I seem to not have DFU or Fastboot. I can boot into system and stock recovery. Fastboot just reboots normally. Trying to use DFU + MiFlash results in the hello packet error. Thanks
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] AnonVendetta:
[MENTION=4515660]adriangb[/MENTION]: There's no reason you would want to boot into DFU, trust me, you don't ever want to get stuck there. You can't flash anything with DFU. EDL is what you want. DFU is a black screen and a red light that stays on and doesn't blink, EDL has a blinking red light. As for fastboot, ZTE removed access to it in the latest updates.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Dunka:
I updated to the Official Oreo Update, all in all I like Oreo but I am experiencing 2 issues. Android Auto and Bluetooth connectivity loss.

I never unlocked my bootloader, thought I'd stay stock, but I was wrong lol.

Has anyone who updated to Oreo able to EDL back safely?

It's been years since I played with my phones, so I am a little rusty.

I'm all set with Qualcomm drivers, device shows correctly in Device manager in Com 3 when I adb reboot to edl

Run edl (B19 Nougat Full), then flash the Fastboot unlock in Mifavor, then run the fastboot unlock commands?

Flash the lastest TWRP?.

no OS, no recovery, edl not working...

hey

i'm new here

so hello everyone

i write this post because i have no idea what can i do else....

i try every method i found on xda (without dissamble) and my axon 7 still have no os...

long story short

some time ago i flash lineage 14.1 using Axon7_EDL_Tool

everything was ok

but one day lineage updater tell me there is update to lineage os 15,1

but you have to use twrp

so i download update

put it to sd card

reboot to twrp

Wipe system,data and cache

everything like i read instruction

then i flash lineage 15.1 in twrp

but it stop - saying error 7

now i have no os, no twrp

and axon stop on "your device will boot in 5 second"

bootloader unlocked

usb debbuging on

i have win10 64b, win7 32b, win7 64b

I installed drivers for axon 7,

i bought deep flash cable

nothing helps.....
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] AnonVendetta:
[MENTION=9521592]wroclawiak[/MENTION]: It doesnt make sense that Lineage would erase TWRP. I flashed Lineage numerous times on different devices, TWRP stayed.

TWRP error 7 usually appears when the ROM installer checks your device asserts and finds that it isnt compatible. You probably have an old TWRP installed, get the latest version from twrp.me and flash it.

If you can get into EDL mode, then either flash the latest TWRP or a stock ROM EDL, it's up to you. Flashing stock ROM shouldnt be necessary if you dont plan on running stock, but i usually do so every once in awhile as a precautionary measure, to ensure that all partitions are kosher, and to update the baseline firmware and bootstack. You can boot into EDL via ADB, or by holding VolUp+VolDown+Power, then wait for a red light to blink/flash in upper left corner.

If the red light stays on then you are in DFU mode, nothing can be flashed in this mode. You will need to use the DFU MultiDL Tool, to transition from DFU to EDL.

Hi.

I'm trying to rollback from Lineageos 15.1 to Nougat b35, but I'm having issues doing so. When I flash the stock edl package through miflash, it flashes okay, nothing wrong happens, but when I boot the phone, it shows the ZTE logo, the 5 sec screen, then the screen goes black and the phone shutdowns. I can flash custom edl packages just fine.

Anything special I need to do to be able to flash the stock rom?

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
If you see the "Qualcomm HS-USB QDLoader 9008" driver on Device Manager, then yeah, you're stuck on EDL. The fastest way out is taking the phone apart and disconnecting the battery, then connecting it again; however you'll have to be very thorough or you might have other problems, e.g. your speakers might fail down the line (they'll fill with iron shavings and stuff unless you place the protective cloth correctly). The other way around this is draining the battery completely. I think other people taped the 3 buttons and left it a day or two, that might work. Or put it in the freezer, but I'm not too sure about that... At least inside of a ziploc of course.

After that, try power and Vol+ to enter TWRP, if you can enter it then solve the problem from there. Otherwise, it'll have to be EDL, but you should be able to fix it from there after this

Do NOT buy the oversize batteries! They'll be the nominal size, this is proven.

Your problem is not the ROM, you can't get offline charging because of the bootstack that you are using. can't help you on that, but [MENTION=8823286]runninghamster[/MENTION] probably can (AFAIK you can try DrakenFX's bootstack that says OfflineCharging-NOFASTBOOT for... pretty much what the name says. get it from the los download links)

Tested the links for the a2017u version and twrp. Seem to work. Use the blue download button. Disable java script for the page.

@jcadduono, can you please explain in layman's terms what verity matching means?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jcadduono:
it means the system image is signed with a verity tree on the end (for verification to ensure integrity ex. that it is not modified in any way)

so the verity matching EDL package will have a bit-perfect system partition flash which means it will boot even with a locked bootloader and verity enabled boot image because it is the exact same as manufacturer distributes. this way, it is also safe for OTAs to patch.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] gpz1100:
So like flashing a signed factory full firmware to a motorola device via fastboot.

I wonder why zte didn't go that route, making it more complicated than need be.

If all the files from the factory B29 firmware are extracted, will they flash via fastboot to their respective partitions?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Altomugriento:

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jcadduono:
Everything except system, I don't know if fastboot does support flashing all of those partitions however, I've never tried.

System is tricky because you have to flash a sparse image, but sparse images created from raw ext4 partitions don't contain the verity table.

I used a trick with the packages xml to make MiFlash flash a copy of the verity table to the right sectors, which fastboot cannot accomplish.

Package xml files are basically dd instructions, which makes them very versatile and limitless in opportunities.

sorry for my english.

the dfu mode is customized by zte .in compared with edl mode .there will need a auth with the dfu protocol ,

the firehose protocol is below :

pc send a command through com ,phone send back a hello packet ,pc send firehose programmer ,phone accept it to sram and execute it ,and enter firehose mode , the pc send command to phone with file followed ,firehose programmer write it to ufs emmc chip .... until all file send and write .

the dfu protocal needs one step more before phone send back hello ,it 's a auth file .i cant get it for now ,let me dig a deep further on the official flash tool in the following days .

i am still waitting someone to report that they fixed their bricked g modle with special cable.:(

i feel like it is my fault that they bricked their device .i must say sorry .and try to help them fix their device .

Please explain a little more:

I have A2017 (China). I want to get the correct system image, and flash it via EDL. I used this program http://www.stupdroid.com/2016/10/tool-systemnewdat-into-flashable-img.html which created two images: system.raw.img (6Gb) and system_new.img (4.4 Gb). Can I use system_new.img for flashing via EDL or I need additionally flash the system.verity_data.bin. How do I get the system.verity_data.bin on working phone (using dd)?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jcadduono:
system.raw = dd of system partition or output of sdat2img.py

system.img = ext2simg system.raw system.img

system.ext4 = simg2img system.img system.ext4

system.verity_data.bin = dd bs=4096 seek=(size of new system.ext4 / 4096) if=system.raw of=system.verity_data.bin

you still need to edit program4.xml for the actual offset to write system.verity_data.bin to, which is the (size of new system.ext4 / 4096) + system's sector start and also add for system's byte start (not / 4096)

Another option is to not include system.verity_data.bin if you don't care about OTA compat or verity, or you can change system to sparse="false" and attempt flashing system.raw instead. You will probably need to split system.raw into 2GB pieces and add more system entries to program XML at offsets because EDL won't handle raw data over 2GB or so. (Timeout writing)

OK, I need clarification on the above statement that both the B29 and B15 package come with b20 fastboot. Is this in reference to the packages listed below ( 1st post of this thread)?

It seems to me, that the B15-New_TWRP restores the B15-NEW boot stack. Secondly, why use another tool (tennear's tool) other than the Xiaomi MiFlash tool?

Maybe this is where people get hung up with their phones, using/combining tools and methods from other threads, that may introduce issues to the method in this thread.

If the MiFlash tool works out to be the "SwissArmy knife" for the Axon 7 (and possibly other models), I don't see a reason to complicate the flashing process any further.

If I am talking/writing out of my butt, my apologies.

Edit: Is the fastboot_unlock package (now also available as a separate package) based on B20_fastboot?
