1 part i dont undestand is the fbop_lock.img where can i get that
[ZTE Axon 7 Guides, News, & Discussion] peramikic:
The step #6 is to backup your current fastboot image. first command creates the fbob file on your sdcard. Second command pulls it from the phone to your computer. Neither is a requisite to unlock but just a backup of current fastboot which gets flashed with new one in next step

fastboot is just not recognizing my device
[ZTE Axon 7 Guides, News, & Discussion] zukers:
I have question about [MENTION=1150948]Starvirus[/MENTION] method for A2017G B03, when sending files to SDCARD

this mean I have to download file TWRP_UnlockBootloader_by_DrakenFX.zip from first page unzip it and send only this one file fastboot_unlock.img to sdcard?

My second question is if after bootloader unlock can I flash this newest TWRP FlashFire ZIP SuerSU from this page?:

Hi,

I have ZTE A2017 Chinese unit. Can I still use this method to bootloader unlock?
[ZTE Axon 7 Guides, News, & Discussion] JKSurf:
Fastboot is not recognizing my device either.
[ZTE Axon 7 Guides, News, & Discussion] azam_:
You can do what I did. Go to device manager. Update driver. Then browse for ur preferred. I m sure there should be a different version. An older version of the same driver.
[ZTE Axon 7 Guides, News, & Discussion] JKSurf:
Yeah I just rolled back to previous driver in device manager. Success!
[ZTE Axon 7 Guides, News, & Discussion] celoxocis:
just to clearify this. this method works straight after one has used tenfar's method to patch the boot.img and recovery.img (twrp)?

or just use tenfar's method to patch recovery.img and keep stock boot.img?

Im on A2017U B27.

I have bootup TWRP and get the password screen everytime i enter TWRP.

I already did format data. After having setup the phone i still receive the TWRP password screen.

My guess is that i need to fix the TWRP decrypt issue before i can proceed to unlock the bootloader? Is that right?
[ZTE Axon 7 Guides, News, & Discussion] Random Username:
Hey, do I need B03 for this to work? I have B02 and an update to B05 is showing up. Never mind. I updated to B03.

I can't get axon7backup to work though. ADB works.
[ZTE Axon 7 Guides, News, & Discussion] nujackk:
Just use tenfar's method to install recovery. And as for the decrypt issue you should wipe all three. data, dalvik/art, and cache. ( in early days of twrp had to do this 3 times, so i would give that a try)
[ZTE Axon 7 Guides, News, & Discussion] celoxocis:

Hi guys, Is there any news if this way of unlocking the bootloader works with B29 update?
[ZTE Axon 7 Guides, News, & Discussion] clementinox:
it doesnt work on B29 just tried it on my device because I was expecting to return it maybe for an exchange.

Would flashing B27 aboot and fbop images fix this? [MENTION=3044858]DrakenFX[/MENTION]

If yes, would you happen to have the link or those files for A2017U ? thanks
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
If you updated using my B29 bootstack, you already have the fbop image, you need to reboot to bootloader and do the fastboot command. But first you need OEM Unlocking enable under Developed options

fastboot oem unlock

That will do a factory reset
[ZTE Axon 7 Guides, News, & Discussion] clementinox:
RIGHT!!! OMG I knew it would be something little. Im so dumb lol been trying this all night! That OEM toggle had the best of me, plus lack of sleep. Thanks Bro!
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
sorry for the delay,

if you update using my B29 TWRP flashable or if you did update to B27 using my old files , You already are good to go for unlock bootloader,

just make sure to enable OEM Unlock, then head over bootloader and proceed with the rest.

Hi all. Read trough this topic I still can't find anything about it. Maybe it isn't the best place to ask still I would like to know. After unlocking the BL of the G model, isn't it possible to flash the ROM of the U version but the Modem of the G version? No chance to has it work?
[ZTE Axon 7 Guides, News, & Discussion] Cyreld:
I've been a little out of the loop on unlocking lately, but are there flags that ZTE can check for warranty reasons?

I'm just afraid to get rid of that sweet $80 screen repair, but I've been itching to unlock for over a month now.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
IF you have Unlock Bootloader, you can give it a shot.

I have use G and Chinese Rom with my U variant and works fine, just remember if you try using other variants roms, just flash BOOT + SYSTEM and you'll be fine.

nop, not that i know off.

if you do it the "Unofficial" way :silly: and need to do a warranty just relock the bootloader and do your RMA.

Has anyone had an issue with call audio? Since I unlocked bootloader on a2017u I haven't been able to hear or be heard during phone call. I have tried wiping and re-installing b27, b29 and even tried CM just for kicks. Everything else works fine though. Any help would be really appreciated.
[ZTE Axon 7 Guides, News, & Discussion] joeanca:
Hey, could you give me a little more direction on how to actually revert to original fastboot? I have the backup and want to lock back up. Since bl unlock I lost call audio.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
Unlock bootloader is not the issue here, I have Unlock Bootloader + root + copses + TWRP and no issue what so ever doing phone calls, they can hear me and I can hear them clearly.

Go back to TWRP, make a backup then wipe data-cache-dalvik. and try again.
[ZTE Axon 7 Guides, News, & Discussion] joeanca:
I just did that, and still nothing. I was thinking maybe some audio keys were lost or something while unlocking bootloader for whatever random reason. I thought so because I have so far flashed B29, B27, and CM, from twrp backups and flashables where everything seems fine except call audio which I know was working right up until BL unlock. I just wanted to try restoring fastboot for the sake of accounting for all variables but unsure on how to do it properly.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
Try this :

* Flash B29 Bootstack

* Wipe Data, Cache, Dalvik, System

* Flash B29 Stock System

See if that help with the issue, as I say before I not having call issues and literally just got a call from a friend and all good.
[ZTE Axon 7 Guides, News, & Discussion] xtermmin:
Question for whoever has RE-locked their bootloader:

When you boot into fastboot, does it list the status as "locked", or "relocked"?
[ZTE Axon 7 Guides, News, & Discussion] joeanca:
It says locked.
[ZTE Axon 7 Guides, News, & Discussion] xtermmin:
Good to know! Thanks! :)
[ZTE Axon 7 Guides, News, & Discussion] joeanca:
Still nothing. Can't think of another reason this may happen. Unless it is related to hardware but I doubt it cause between the time I had a call right before unlocking and noticed the bug shortly after. In any case I am not blaming anyone I really appreciate all your work and just want to sort this out.

edit: So I am fairly certain that it has to do with the dolby enhancements as even other sounds won't work unless I turn off the dolby on the status bar. Can you give me a hand on how to restore the bootloader backup? I am guessing my dolby enhancements might be in there.

edit 2: flashed b20 from the zte website on adb sideload and all is back to normal.
[ZTE Axon 7 Guides, News, & Discussion] Mart Son:
Yesterday I unlocked my axon 7 A2017G B03. In bootloader I could read the word `unlocked'.

After rebooting I was offered the update to B05, but could not install because of something mismatched. So I downloaded the full Rom from ZTE and installed it. Now I am again locked!

Why is it again locked? Maybe because I unchecked oem unlock in developers options before install? Sorry for my bad English.

[ZTE Axon 7 Guides, News, & Discussion] joeanca:
So finally got my troublesome b29 for a2017u working with root and call audio working *WITH UNLOCKED BOOTLOADER* this is very vague in terms of the links so anyone with more energy at this point is welcome to edit the links in.

- download the b20 zip file from zte

- download twrp3.2.2 from one of the other forums

- unlock bootloader

- flash stock recovery (I don't know where I found one)

- reboot stock recovery

- adb sideload update.zip (update.zip is the file from the zte support website)

- once you have booted and everything is good update from b20 using over the air updates downloaded from the phone to b27, then again to b29

- reboot bootloader and fastboot flash recovery nameofrecoveryfile.img

- vol up + power boots twrp.

- flash the Superuser2.65 provided in this thread.

Hope this helps anyone who has had the same trouble I had with call audio after trying to get up to b29
[ZTE Axon 7 Guides, News, & Discussion] xtermmin:

Hello guys, I wanted someone here to confirm if what I understood is right or not before I start unlocking and rooting, right now I am on completely stock MiFavor B29 so the only way to get my phone unlocked and rooted is to revert back to B20 by using the Updat.zip from ZTE_USA website, then taking the OTA updates till B27 and afterwards start to unlock the bootloader by following the instructions from the method in OP then take the Updat to B29 by flashing the 2 files BootStack and System+Boot and the final step is to flash SuperSU 2.65. Is that right?

Thanks in advance guys.

But in which mode do I get the portnumber.

When the phone is running I only see in the win10 adb interface but there is no new comport.
[ZTE Axon 7 Guides, News, & Discussion] *mj13*:
Wait I just realized what you are discussing is tenfars's tool for flashing recovery, but you are in the unlock bootloader thread....

What are you doing at this point? If it's installing the recovery with a currently locked bootloader go to that thread and read, there is a different method to getting the phone into the correct mode from the U variant. I don't recall offhand but it's discussed there. After you have twrp installed your can then proceed to this thread to unlock the bootloader
[ZTE Axon 7 Guides, News, & Discussion] Mart Son:
Hello,

before I start again with the whole procedure of unlocking bootloader I want to ask if anybody unlocked the A2017G and updated from B03 to B05 and it's still unlocked. In my first try I relocked my device by flashing the full rom B05, because the OTA update showed an error though I flashed the stock recovery.

TIA

Mart

[ZTE Axon 7 Guides, News, & Discussion] Cyriex:
I'm in a similar situation

I just received my new Axon 7 and would like to confirm the same thing. Only difference is I have not even gotten into it yet to apply any updates. I bought it from newegg with US warranty, and there have been absolutely no changes made by me thus far. My end goal is to have TWRP, root, ad block, titanium, and xposed with "stock" OS. If I need BL unlock, as I believe I do, then Id like to avoid giving ZTE notice through their official route.

Also I was wondering if that whole password issue with the encryption would be avoided if no screen lock code is chosen beforehand, or am I totally off track here?

Thanks for all your hard work guys! :good:
[ZTE Axon 7 Guides, News, & Discussion] `SBR`:
yes this will work.

or

as you're already in B29 you can try this approach as well.

1. Download the DrakenFX Stock B29 TWRP files (bootstack and System Files) . put it in SD Card as unlocking will Wipe internal storage.

2. OEM Unlock in Developer Options.

3. Flash the TWRP Recovery using Tenfar method.

4. Go to recovery Flash the Bootstack (and system files is optional as you;re already in B29)

5. Go to Boot loader and unlock the Bootloader using the fastboot command

6. it will ask for option use the vol button to unlock it. it will wipe the internal storage. (makesure you have the backup of important files)

7. go to TWRP, do a format of DATA, to get rid for Encryption Issue.

you need to have unlock to have root in B29. if you're unlocked there are no encryption issue, make sure you wiped the Data from TWRP after unlock.

I have the same configuration of boot (B03 EU) and system (B29 US). Apart from not being able to access Dual SIM settings I also have trouble setting custom ringtones or notifications - they don't show up in sound setting drop down. Also can't move/modify any system files, - it seems that despite the bootloader being unlocked the system remains read only. Even if I choose r/w in Root Explorer. Other than that didn't notice any other glitches.

Perhaps it's worth trying B05 boot + B29 system combination. I'm planning to try that.

yes you can relock the bootloader, keep in mind you'll loose everything in internal storage.
[ZTE Axon 7 Guides, News, & Discussion] azam_:
could you give me a link to follow?

1* reboot via adb or manually

2* using fastboot lock bootloader

fastboot oem lock

3* DONE expect to WIPE Data - Internal Storage, so SAVE anything important from such storage (internal storage)

P.S. SDCard will be safe.
