There was something odd about the OP file. It had a file which was not in the manifest and the footer on the zip was invalid. This one is proper (full sig file). This would not be possible to replicate without the private signing key. There might be a tweak in the fastboot code for device specific check, but everything has been so vanilla so far, I am positive it will work
[ZTE Axon 7 Guides, News, & Discussion] dennis96411:
Won't this stop working if you're on a build beyond B20?
[ZTE Axon 7 Guides, News, & Discussion] jkuczera:
Hopefully it's the same for that everybody's getting. I had mixed it up with another file I was trying for the update software.
[ZTE Axon 7 Guides, News, & Discussion] jkuczera:
OP link updated!
[ZTE Axon 7 Guides, News, & Discussion] TeutonJon78:
Ok, that's what I thought. It will be interesting to see how deep they integrated the IMEI checking.
[ZTE Axon 7 Guides, News, & Discussion] peramikic:
Yup, so we have to sideload B20 in case new one comes out. We already have a copy of it, just no one has tried the process from B18 like that AFAIK. Plus ZTE would have to build new B21_boot anyways for people who want to unlock after B21

So do not apply any OTA from ZTE after getting the phone, since they might fix B20 somehow
[ZTE Axon 7 Guides, News, & Discussion] TeutonJon78:
Won't sideloading B20 fail though? It's going to be checking that is updating against B18, not B20_boot or B20+ version. We would need a full backup of clean B20, or the fabulous unavailable-as-of-yet system images.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
you mean this, Unlocking the Bootloader? so yeah i already unlocked :D :P , i didn't wanna do it but hell of it ...now reinstalling everything LoL :D (yeah "fastboot oem unlock " will wipe device )

P.S. DON'T GO OVER ZTE Community telling about our finding here, i'm not sure if they are all over checking this stuff but lets keep this just XDA wise
[ZTE Axon 7 Guides, News, & Discussion] peramikic:
It would be great to get a second file so we can compare and make sure, but this is all standard code from android source tree, just using logo background. The use of old oem unlock command is also interesting, but it might be a legacy support that Google removed since OP3 unlock is the exact same way.
[ZTE Axon 7 Guides, News, & Discussion] TeutonJon78:
Was this your update file? If so, it doesn't mean it's generic yet.
[ZTE Axon 7 Guides, News, & Discussion] KyJelly69:
Great work. What about relocking? Does adb work or are system images needed?

I think he modified the first one, the second one is the same he DL'd
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
mmmm the 2nd one is the one i flash to get access to Unlock Bootloader :eek::silly:
[ZTE Axon 7 Guides, News, & Discussion] jkuczera:
We really need to keep the clarity here. In the first post I had accidentally uploaded the wrong file which was the one I had modified. I updated the OP with the correct file which was the same original download during update.
[ZTE Axon 7 Guides, News, & Discussion] rczrider:
So when I get my A7 next week, is there anything I can do to help out?

Or just sideload B20 (which no one has done, yet?) and then flash the file in the OP?
[ZTE Axon 7 Guides, News, & Discussion] reddrago:
I feel like they voluntarily made this easy somehow, could also be that they were way too busy to work on the bootloader and just threw something together as fast as possible. Nonetheless lets hope they are too busy to check XDA. Now I just need my phone can't wait for next week anymore.
[ZTE Axon 7 Guides, News, & Discussion] peramikic:
You could officially void your warranty so we can get the second file for comparison :angel:

But sideload B20 then b20_boot will be good to know it works on gray as well, I hope that both models have the same fingerprint. If not we will need the Grey version B20 and B20_Boot
[ZTE Axon 7 Guides, News, & Discussion] reddrago:
Can't we just update to the B20 from the update screen instead of sideloading?
[ZTE Axon 7 Guides, News, & Discussion] peramikic:
They just used the standard way of doing it that is already provided in the base code, it's all vanilla

---------- Post added at 07:34 PM ---------- Previous post was at 07:34 PM ----------

It might get pulled and replaced with something that does fix this loophole
[ZTE Axon 7 Guides, News, & Discussion] swehes:
So can we clarify what sideloading means?
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
i'm sure that's possibl just need to change the ext. from " .up " to " .zip "

same way i did with the file provided by OP
[ZTE Axon 7 Guides, News, & Discussion] peramikic:
In this instance, it is placing the OTA zip file manually on the /sdcard and rebooting to boot loader to perform the update instead of using the ZTE app
[ZTE Axon 7 Guides, News, & Discussion] KyJelly69:
But can it be relocked if I need to send it in for warranty?
[ZTE Axon 7 Guides, News, & Discussion] Jose-MXL:
[MENTION=3044858]DrakenFX[/MENTION] hehehehe, can you or would you try to re-lock it? Just asking :), peace out :)
[ZTE Axon 7 Guides, News, & Discussion] djona12:
Great work! Didn't take too long to get to the bottom of this unlocking update... I'm almost disappointed by zte ^^'.

Thanks to everyone working on this!

Is there a way to make this update file to work on any updates, like directly from B18, from future updates or let's say on european software ? :D

Probably just use the locking command since unlocking works that way.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
LoL, just finished re-installing and redoing everything again after unlocking....... If I lock the bootloader back I'll have to redo the whole thing :( ....

Let's hope twrp is just around the corner and I'll lock and then unlock again :) :D

[ZTE Axon 7 Guides, News, & Discussion] dennis96411:
Updating without permission? Yikes. I hope they haven't already pushed out a new build just to invalidate this method.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
Is the "B20" update which I assume he just got his device and force updated.... But still forcing updates not cool....
[ZTE Axon 7 Guides, News, & Discussion] allan1229:

[ZTE Axon 7 Guides, News, & Discussion] Jose-MXL:
Huh... Be patient man, there are other more impotant things to do such giving a try to unlock EU phones, I don't think we will be talking about root first anyways, TWRP should be a priority
[ZTE Axon 7 Guides, News, & Discussion] bosetsu123:
I was able to flash to the file uploaded by the OP, but I don't seem to have the option the unlock the bootloader. Do I need to use adb to send the command?
[ZTE Axon 7 Guides, News, & Discussion] jkuczera:
You need fastboot on your desktop (guides available for all desktop operating systems via internet search).
[ZTE Axon 7 Guides, News, & Discussion] bosetsu123:
Got it! Thanks! Unlocked finally :D
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:

Downgrading from B20.Boot to B20

Could someone please figure out how to downgrade from B20.boot to B20 via SD card? I want to be able to revert to B20 just in case. Thanks.
[ZTE Axon 7 Guides, News, & Discussion] xtermmin:
Currently not possible, as the B20 OTA only applies on top of the B18 launch firmware. We're still waiting on ZTE to release full system images.
[ZTE Axon 7 Guides, News, & Discussion] rczrider:
So there's B18, which the Axon 7 (currently) ships with. B20 is the "standard" and most recent firmware update. "B20.Boot" is identical to B20 but unlocks the bootloader? Or its only purpose to unlock the bootloader (and so requires B20 already be installed and is applied on top of B20)?
[ZTE Axon 7 Guides, News, & Discussion] bkores:
I get a build fingerprint error when I try to downgrade via the SD card.
[ZTE Axon 7 Guides, News, & Discussion] xtermmin:
B20 makes changes to a bunch of system files (13 patches), while B20_Boot only makes changes to boot.img and recovery.img. B20_Boot can only be applied to B20, can't go from B18 to B20_Boot directly. Have to go B18 -> B20 -> B20_Boot.
[ZTE Axon 7 Guides, News, & Discussion] rczrider:
That's what I figured and that makes sense. Just clarifying. Thanks!
[ZTE Axon 7 Guides, News, & Discussion] TeutonJon78:
It should allow relocking since it enables the fastboot commands. However, they will know that you altered the phone (if they care to check), since your bootloader would still be B20_Boot, rather than B20.

And if you flash it back to B20 somehow (which as of now we can't), then you couldn't relock it. So, even if you flash this separate bootlock method, they can still easily tell you did it if they check.
[ZTE Axon 7 Guides, News, & Discussion] KyJelly69:
Once we get stock images everything will be ok
[ZTE Axon 7 Guides, News, & Discussion] TeutonJon78:
That's two assumptions that might not play out. We may never get stock images (China's been doing it from release on multiple phones, many for Europe have full releases, AFAIK, ZTE USA has never posted a full image for any phone).

And, we don't know yet if anything internally is changed by the unlock (like KNOX). It seems a little unlikely they did, but only time will tell. For example, that fastbook "Device tampered" flag might be triggered the second anything is flashed in an unlocked state, and it might not be able to be reset.
[ZTE Axon 7 Guides, News, & Discussion] fix-this!:
Now that the bootloader can be unlocked it has peeked my interest. Sadly the phones are on backorder for up to 6 weeks. Im just waiting to see if this device gets any dev support as in aosp roms.

---------- Post added at 02:31 PM ---------- Previous post was at 02:30 PM ----------

There is no knox on a zte. Thats samscum.
[ZTE Axon 7 Guides, News, & Discussion] Gachmuret:
That's an easy one: relock first, then flash to B20... btw, would be nice if someone could try to relock with flashboot commands to check if it's possible

And couldn't it be possible to extract a flashable image of B18 somehow and integrate B20 in it afterwards, or extract straight from B20?

Another question: Will there be OTAs and updates for users with unlocked bootloaders? And if so: will there be two builds, one for locked (i. e. B21) and one for unlocked (i.e. B21_boot)...
[ZTE Axon 7 Guides, News, & Discussion] xtermmin:
But there might be something LIKE knox.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
You can Pick-up one from Swappa if don't want to wait :D ....either way all sales comes with Passport 2.0 from the original sale.

P.S. howdy man haven't see you since the LG G Stylo

i really doubt ZTE have implemented any sort of Top Notch security like knox or anyone else....not even LG have something like that or have something at all.
[ZTE Axon 7 Guides, News, & Discussion] fix-this!:
Ive seen you around. Yeah I didnt have the stylo for long. Went to the nexus 6p, 5x. Then went iphone for awhile. Now im on a moto g4 plus. Liking the looks and reviews of the axon but ill wait for roms first.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
yeah i really like this device, is super smooth - Sound is amazing and loud (you can image how this sound with headphones) only downside is camera but i have high hopes ZTE will fix that with future updates.

P.S. something awesome is coming and will open even more door for great Development. :D
[ZTE Axon 7 Guides, News, & Discussion] Gachmuret:

[ZTE Axon 7 Guides, News, & Discussion] QAM:
Be wary that while some brave souls in this forum took the time, effort, and risk to get us all the bootloader to be unlocked, please do NOT share this info outside of XDA.

Just a reminder to all of us here,and especially for those of us who are active in the ZTE USA forums.

Last thing we need is to have ZTE find a way to disable the method found here.

Thanks.

"So what you want me to do 'bout that?'"
[ZTE Axon 7 Guides, News, & Discussion] daneoleary:
I'm using the Axon 7 with Verizon right now. You have to allow roaming to access LTE speeds, but otherwise it works just fine. From what I've read, ZTE is in the process of getting Verizon to sign off on the Axon 7 so that it has full network access, but it can still be used in the meantime.
[ZTE Axon 7 Guides, News, & Discussion] Son Rise:
Will this work also on galaxy s7 edge Sprint?
[ZTE Axon 7 Guides, News, & Discussion] TeutonJon78:
Once the device is locked, you can only flash full images or OTAs that match the ZTE signature. None of which we have currently, and may never have. Even if you backup the partitions, you'd have no way of generating a package to match their crypto signature.
[ZTE Axon 7 Guides, News, & Discussion] Nameless One:
Is the galaxy s7 edge sprint a ZTE Axon 7? no? then it is unlikely to work, the file to be downloaded looks at a cursory glance to be very device specific.

Or are you asking (judging by what you quote) whether the "not telling ZTE about this" will work on the galaxy s7 edge sprint?
[ZTE Axon 7 Guides, News, & Discussion] anaya1213:

[ZTE Axon 7 Guides, News, & Discussion] peramikic:
You should still be able to sideload B20 OTA first, although i'm not sure if anyone tried it yet. Just be sure to NOT run any updates when you get the phone to make sure. Then check what the current status of OTAs is. There was a talk of not being able to skip WI-FI step during initial setup, so to avoid push update, i suggest disabling the internet on your wifi until you can get in and disable wifi after setup. The OTA should not flow over cell data

[ZTE Axon 7 Guides, News, & Discussion] tolymatev:
Just tell them with the announcement and all the excitement surrounding the bootloader unlock news you went ahead and requested the unlock, slept on it and when you woke up you thought about your warranty, and changed your mind.

I wish i can unlock my galaxy s7 edge Sprint :(
[ZTE Axon 7 Guides, News, & Discussion] Jose-MXL:
Dear sir, may I provide you with an advise and my opinion?:

What's done is done, you are exposing mentality that definitely is not what we want to show on ZTE. Unlocking the bootloader "under the radar" already gives signs that our intentions are a little on the dark side, we are not unlocking "under the radar", we were trying to streamline the bootloader unlocking process (at least I tried polling people on their bootloader requests to capture the boot OTA).

If that gives a tiny tiny chance that they not strikethrough your IMEI directly, well, you know, why not...

Updated: although my opinion on being careful stands, I shall not recommend returning the phone under any circumstances not related to a real issue (I didn't, but implied that the phone should be returned if the customer isn't happy with it).
[ZTE Axon 7 Guides, News, & Discussion] Yellowflash99:
My interest in this phone increased dramatically in the past few days. Now that bootloader can finally be unlocked no way I pass up on it!! What being said on XDA only stays on XDA!
[ZTE Axon 7 Guides, News, & Discussion] tdgillihan:
Right, and nobody from ZTE would ever dream of being a member of XDA....
[ZTE Axon 7 Guides, News, & Discussion] TeutonJon78:
It still alters the system partition, which may make future OTAs fail, depending on how they structure those. If they approach it as "you're unlocked and on your own", then you won't be getting any OTAs regardless of if it was done legit or under the radar, as the partition signatures won't be matching what they expect for your OTAs. If they push out separate OTAs for each path, then you'd want to be officially unlocked, because otherwise your IMEI will be given the locked OTA version which will fail.

For those unofficial unlockers, they should hope ZTE pushes out some sort of combo OTA, otherwise they'll be on B20_boot until they get a 3rd party ROM or factory images from ZTE -- or they have lots of per partition flashing ahead of them from other's backups.

Edit: A lot of these questions will be answered once the B20+ update from ZTE comes out. Then we'll know how this will be handled.

Edit2: and for those of you wanting to keep the non-ZTE unlock secret, well, the Chinese forums users have already posted it all over there: http://www.myzte.cn/thread-312413-1-1.html

And of course, some of the users think they can flash the US version on their Chinese version. :eek:
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
But if all the A2017U files work for them you know what that means right?

Mean We can use their Factory images to recovery from Softbricks and just replace our system , boot, modem, etc from our variant the A2017U.
