Hey there. I'm still working on backups and apps tests before I wipe my device (I've found out there's a lot of spread files to organize in my 128GB phone... Lol), but I think I'll finish and upload your file on the next couple days. Meanwhile I've read your OP from the guide's thread and I have some doubts. Could you clarify them to me please?

1. You've said OTA updates work after bootloader unlock but can't confirm on TWRP. So if I want to update the stock ROM I'll have to download the file and flash it everytime there's a new version, right? ZTE posts a link somewhere or do I have to wait for some user on XDA to upload it and share? TWRP flashes only custom ROMs or can I use it to flash the originals too?

2. Are there different versions of the same ROM? In one topic you mention a B13 EDL file... So is there a normal version which ZTE publishes and a modified version someone made just for the case of recovery via EDL?

3. Using your guide, in the future will I be able to change my chinese Axon to US stock ROM or any other custom ROM I choose? Or do I have to make other steps and read other threads to do so? If I install a custom one, is it possible to turn back to stock?

4. What may I have to do in order to secure myself from any failure? Do I have to make a nandroid, recovery and bootstack backups? Are these things only possible to do using TWRP?

Sorry for these basic questions, I don't want to bother you or anyone with noob stuff, but I still need to clarify them and you guys always have all these great knowledge. Thanks again for your patience and time! =)

Edit: a friend for other thread posted a link for the official ZTE releases: http://www.ztedevice.com.cn/support/...ED0C72D6046C78
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
1. If you want to update via official OTA, we need the stock recovery. I haven't tried updating thru twrp. Else, another method is to wait for someone to modify the ota for it to be twrp flashable.

2. Yes there are different versions. There's the official one which needs stock recovery, another one which is twrp flashable and another for edl using miflash program.

3. Once you have unlocked bootloader and twrp, you can flash any custom rom you want. Just read the the thread for each roms instructions. You can always go back to stock by restoring twrp backup if you have or flashing the files you have for number 2 above.

4. Full twrp nandroid backup is always the best. Or go back to stock again using number 2 methods.

Hope I answered your questions.

Lastly, please check your link. It seems truncated.

Thank you.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
Hi again. Many thanks! So far I don't have more questions. Later on today I'll follow your guide. Hope everything goes right so I don't have to bother you again. Lol

Oh, here is the complete link:

I had to break a line after support/ because it is truncating again. Do you know if ZTE publishes a similar page with stock US versions?
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
Hi there.

Backup worked! Hope it helps you. Here is the link from my Google Drive:

https://drive.google.com/drive/folders/0B1dRTaiOSxGZZ015dlQycWRVVUk?usp=sharing

If you can't access, please let me know. I'll move the files to another place next week, so if you can, download them for your computer, ok?

Now I'll try next steps of the guide. =)

Hope everything works fine.

Cheers

Edit:

Seems that step 7 went well, but when I reboot holding power + up, all that I get is the screen on the photo. And if I choose Recovery using volume buttons, it returns to the same screen... Any help?
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
try to do the step 7 again but after it starts to countdown, hold power button to restart. When the boot loader screen shows up, press volume to choose recovery.

OR when the countdown appears, hold power and UP buttons. when the phone restarted, release power but continue to hold up until it enters twrp.

BTW, Thank you so much for the stock boot/recovery files. I won't try them just yet until there's a new OTA.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
You welcome. Let me ask you, why do you need these files? You can only update OTA with them? And do you use a custom ROM in your phone or you're still with stock chinese?

I tried both methods you said and it always get back to that screen. One time when I selected Recovery from the list, it showed a black screen with the Linux penguin logo in the center and then turned the phone off. Do I have to roll back to Marshmallow in order to achieve this? If so, how can I do it now since the original bootloader with chinese characters seems to be gone?
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
I don't use custom roms, they're a lot buggy than the stock one i think. And yes, I can only update OTA using stock recovery.

Ok, try this command if this works.

"axon7root.exe -p COM# -b -r"

You can flash back the original boot and recovery usig the files you backed up. Just rename the current boot.img and recovery.img to anything else then rename your backed up files to stock.img and recovery.img. then use again the command "axon7root.exe -p COM# -b -r" to restore.

Or maybe you can explore the axon toolkit in the forums.

Else if it really goes wrong, you can always miflash back to b17 or b13MM.

Axon is really quite frustating at first when flashing/unlocking bootloader compared to other phones.

I can also remember I saw that penguin once before.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
Hi. Now it only boots to that error screen... What should I do? Use EDL to restore an old stock ROM? Could you please give me the instructions or point a link?

When you say "Just rename the current boot.img and recovery.img to anything else", where can I find these current files and how to rename them?

Another doubt I have is about bootstack. Is this the same as the bootloader? I see a lot of people making references to it, but I couldn't find a nice explanation on Google. Is this a system file?

About custom and original ROMs, it is sad because the Axon software team ripped off a lot of nice features of pure Android. Among many other things, I can't for example access screen saver (former daydream) when I put my phone in a dock to charge, one of the features I like most. I had to create a system setting shortcut using Nova Launcher to access this feature, and still I can only use the stock clock, although many options from other apps are available (nothing happens when I select them). The missing "Ok Google" voice search on any screen is another heartbreak thing I've discovered on chinese stock ROM. It is getting worse as in the last MiFavor 5 update it stopped working completely, even when I have the Google Search app or Android Auto opened, and sometimes it shows an error message while booting related with the %1$s string they use to this function. Also, after this last update, Google Play Service is very buggy and a lot of apps doesn't work anymore. I think I will roll back to B17 and wait for a new OTA or try Ressurrection Remix to see which bugs it has. Lol

Thanks for your help, friend. I am learning a lot! =)
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
Remember those files you uploaded for me? stock_boot.img and stock_recovery.img

Rename them to "boot.img" and "recovery.img" and put it in the folder where the axon7root.exe is. It may overwrite the current files there, so probably you may want to move the existing images to a folder first.

Then run the command:

"axon7root.exe -p COM# -b -r"

This will restore your original boot and recovery.

If this still doesn't work, message here and let's try another method to restore it.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
Got the following message this time: " Image load failed with status: 9". If I include the .img in the file name, get this one: "PblHack: Error - 4 device no response".

I am entering EDL mode holding Vol Up + Vol Down + Power and my phone is showing as ZTE Handset Diagnostic Interface (DFU) on COM port.
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
I think the problem is that your device isn't entering EDL mode. try doing the button combos again and see if it works. you should only see 9008 mode in device manager.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
It didn't work. I see the DFU message again.

How about I try to flash B17 via MiFlash in this DFU mode?
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
it won't work. miflash only uses edl mode. Can you verify if you can boot into fastboot? power + vol down.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
Booting in fastboot freezes on the ZTE blue logo screen with white Powered by Android message down.

I'll make a search here on XDA to see if there's someone with same situation.
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
try to see if the PC detects it as fastboot device. On the command prompt, type "fastboot devices".

if it detects, try these commands if they work:

fastboot flash boot "stock_boot_backup.img"

fastboot flash recovery "stock_recovery_backup.img"

if both files succeeded flashing, reboot your phone.

be sure to put the stock backup files on the same folder you started your command prompt.
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
I found something which hopefully helps. Just google translate this page.

IT IS BAAAACK!!! YEEEESS!!!!

Man, I was worried A LOT. I stayed all last night alone walking in circles saying to myself "you shoudn't have done this"... Lol

I was able to get it back to work following instructions on this post #31 https://xdaforums.com/axon-7/help/2017g-dfu-mode-investigation-t3511191/page4

Drained all the battery last night (but I think it's not related), connected USB today while holding Power + Vol Down, so the phone started and stayed on the blue ZTE logo screen (is this supposed to be fastboot mode?). So I openned command prompt and tried out "adb services", device showed up as "? device". Then I did a "adb reboot edl", the phone entered EDL and I followed your instructions to restore original files.

Thanks a lot for your time! Thanks God my phone is back!!
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
Glad to know that you're phone is back.

I hope you didn't get traumatized from the experience. ?
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
Yeah, I survived! :D

The screen it was booting was your custom recovery? The next step was to install TWRP from it?
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
The step using axon7root should install twrp. but that's where you got trouble with.

maybe try axon toolkit? it has an option to install twrp and unlock bootloader I think.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
I see. So the bootloader that was changed? Because when I hold Power + Vol Up, I enter a screen with many options in chinese. And when I tried your tool, I was entering a different screen with the items (power off, restart, fastboot, recovery...) all in english. And this is so much better to understand than the chinese original... :laugh:
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
The ones in chinese is the stock recovery. The ones in english is the bootloader menu where you can choose which to boot, whether recovery, fastboot etc.

Once you unlocked your bootloader, that menu in english will always be there on every boot for 5 seconds.

The chinese recovery is what you need to replace with TWRP to flash things especially the BL unlock zip if you want to unlock your BL.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
Thanks for everything, man! I think I've learned all I needed. I will leave my phone stock to use my Daydream View that will arrive soon, and in future I will try again to unlock and root with AxonToolkit.

One last noob question that I've never found the answer: bootstack is a file related to a specific ROM to make it boot? Does every stock release have their own bootstack?
[ZTE Axon 7 Guides, News, & Discussion] Aj-jss:
Hey guys I've got a question. Does everything including the whole operating system be wiped and reinstalled when a full ROM is flashed on the same ROM?(for example installing B17 stock ROM(2.8GB) full ROM package on B17 stock ROM again)
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
From what I understood, it contains mostly boot image and boot related files.

Usually, they split the ROM into bootstack and system images.

If for example you are going to flash a US rom on a chinese unit, you'll only have to flash in twrp the system image.

If you flash the bootstack of that US rom, you'll probably lose signal or worst won't boot.
[ZTE Axon 7 Guides, News, & Discussion] rafabrasil85:
Wow, thanks again for all the knowledge! I've seen people loosing signal and having to flash a modem file from another ROM in order to make it work. Still have a lot to learn, but for now I'm done. Thanks and have a nice day!
[ZTE Axon 7 Guides, News, & Discussion] r00l3z:
so i have to go back to stock recovery, for the update to work right?

I went to stock recovery and installed from sd card, not sure where the double tap came from, just install from sd (Easy to find that option, it has a whole lot of chinese characters and sd in the middle) and the right option to install...

This update things don't work for no one Basta! Maybe the update file here is corrupt!
[ZTE Axon 7 Guides, News, & Discussion] spiwar:
Okay, I've got this all figured out, for those who still can't flash:

- You CAN'T flash through TWRP, the update files expects you to have stock recovery

- If your phone is encrypted, you CAN'T install the update using the phone's internal storage (internal sdcard), so you must copy the update file to an external SD Card to flash (If you don't have a SD Card just get one or borrow one from a friend)

So, quick walkthrough:

- Download the file

- Put it into your External SD Card, you don't need to rename it, it just needs to be in your external SD, not internal.

- Reboot into recovery mode (volume up + power button), you must have STOCK recovery.

- Ignore all the chinese ****, just select the one with the word "SD" on it

- select the file, update and enjoy Android 7.1

What does nougat bring that people are willing to go through all this hassle.

I wish they would introduce multiwindows, it's ridiculous that this phone doesn't have it.
[ZTE Axon 7 Guides, News, & Discussion] bornlivedie:
because the custom roms are very green?

problems with camera, sound, bluetooth, fingerprint sensor, general performance, battery, missing features, etc.

You can't really compare.

Multi window was first introduced with Nougat, and ZTE's Nougat update has multi window.

Also working on stock B15 and Bad Boyz.
[ZTE Axon 7 Guides, News, & Discussion] spiwar:
The updated bootstack is in the new chinese nougat.

If you are on twrp , flash B13 bootstack, links are a few posts back, so u can return to stock recovery

After that, follow my instructions (also a few posts back from here) to update to chinese nougat.

After that you have the updated bootstack and then you can flash twrp and then any other nougat roms you want

The process is very simple, should only take 30-1hr to complete

Those modem didnt work for me though, unjustified bootstack and the phone refuses to boot, draken's bootstack and it resulted in a soft brick (was able to recover with EDL)

Now with this new bootstack everything is working purrrfectly
[ZTE Axon 7 Guides, News, & Discussion] otaconremo:
I did try your steps restoring to b13 bootstack via twrp. but it gives me error status 8 upon installing nougat on the stock b13 recovery.

I solved it by flashing again to full b13, formatting data, then update to nougat.

I wonder why each of our units aren't behaving the same. using udevs LOS, I had no problems except for the shortcomings of LOS itself like the speaker. I even used it for a whole week.

But when I tried to flash stock nougat (chinese full or US with chinese N modem), they always gave me signal problems with my sim. Maybe my phone's problem isn't all about the modem rather the stock N system itself. Since it's okay with LOS.
[ZTE Axon 7 Guides, News, & Discussion] spiwar:
my bad, I forgot. I use miflash to flash full B07 (to recover from flashing N bootstack), update to full B13 and then proceeded to flash chinese OTA nougat (thru stock recovery with update placed in external SD). After that twrp and business as usual.
