[UNLOCK] Bootloader Unlock Package

Introduction
This is the bootloader unlock from ZTE. It was provided to me in private email by a ZTE engineer.
Warning
This package is for the USA version of the Axon 7 Mini (tulip) running 7.1.1 b14 firmware. If you are running any other device or firmware version, it may not work.
Note
After some testing, it appears that the Axon 7 Mini is not locked in any way. In other words, apparently neither this package nor tuliptool's unlock are required to flash custom ROMs. The only apparent advantage to flashing this is to get access to fastboot, which provides a way to flash a custom boot and recovery (among other things).
Flashing Instructions
Place axon_mini_unlock.zip on the root of your sdcard.
Reboot into recovery.
Select "Apply update from SD card".
Select axon_mini_unlock.zip.
Usage Instructions
After the package is flashed, you may boot into the bootloader:
adb reboot bootloader
Once in the bootloader, you will see an on-screen menu. Additionally, you may access the typical fastboot commands:
fastboot oem device-info
fastboot oem unlock
fastboot flash ...
... etc ...
Download
axon_mini_unlock.zip
md5: ea8f1a21c8a46b3045d00f17a37fe359

So, after this is done, I can flash TWRP through fastboot and tuliptool is no longer necessary, correct?

Yes, that is correct.

Is this something your contact mentioned or something that you believe based on your experience?
Any harm in trying it on verdandi/other versions without any risk of bricking?

Any way to confirm this is also the case with other versions as well?
Thanks TDM.... you're going to have a lot of Canadians asking about verdandi as it is quite cheap here at the moment. Better get those questions out of the way early. The source is released, same kernel version as the U.S. one with some small differences with drivers (from what I can see) and I am sure that if people know that custom roms are possible on that version (not bootloader locked forever) it would be appreciated.

Yeah...verdandi is stuck on Marshmellow. But since it has different hardware it could brick if this is tried.

The ZTE engineer is USA based, he is not on the China development team (read: probably a support engineer). He said: "I attached the unlock update zip package, please try it. It is based on B14 build."
Sorry, that's all I have to go by for "official" information.
I do not want to be responsible for anyone bricking their device, so I cannot claim that this bootloader will work with anything other than a tulip device running 7.1.1 b14.
If you want to try and report back, I'm sure others will appreciate it. But I can't be responsible for the results.

Oh, and here is some more information to help you decide...
The volume key combo to enter EDL is handled by aboot (bootloader, eg. the thing we are flashing). This means even if you aren't currently able to use the key combo, you should be able to use it with the new aboot here. And if you can get to EDL, you can never really brick the device.
The volume key combo is detected very early in the aboot code. Like, first thing after basic platform init. So even if this isn't compatible with your device, it's likely we could restore the old aboot (assuming you back it up first, of course).
I'm convinced that the tulip is not locked based on my investigation today. So I have no idea if this aboot is properly signed. If your device is locked and this aboot is not signed properly, the lower boot loader won't load it. I'm not quite sure if that kicks you into EDL or not.
Not sure if that makes the decision easier or harder...

How did you come to the conclusion that tulip is not locked to begin with? If we don't need tuliptool or this aboot, how can I check verdandi if the device is the same 'locked but not really locked' state?
I will have a read about backing up aboot and see what I come up with concerning getting into edl.

So here's the deal...
I initially assumed the bootloader was locked because... well... it's supposed to be. So I found the place in aboot code where it checks the lock flag in the devinfo partition. I used the firehose to write unlocked to that flag. Then I built TWRP, flashed it and it booted. So I assumed everything was working just as I expected.
Today, I flashed the aboot with fastboot support and ran "fastboot oem device-info". It said that my device was locked. So I went to look and, sure enough, my devinfo partition flag was still set. Hmm, that's odd.
So I wrote locked back to the flag. TWRP still booted. Now things are looking pretty suspicious.
But maybe the new aboot doesn't even support locking? So I flashed the original b14 version of aboot and TWRP still booted.
That's pretty hard evidence that aboot is ignoring the lock flag. I don't know what they did -- whether they just removed the code that reads the lock flag or introduced a bug or what.
This does not necessarily mean that the lower layers are unlocked. That is, the lower boot loader may still required a properly signed aboot. I don't know, and I'm not ready to brick my device trying to find out.

Hmm... Looks like this package incompatible with ZTE/P852A11/tulip.
Got error while trying to flash it by stock recovery. Error message says that it is for A12 version of tulip.

Ah, yes, you have the euro model. See the "calling all mini owners" thread, posts #76 and #77.

Rooting the stock ROM will require that you remove verity, so that the OS won't refuse to boot once you've made any changes to the system partition. You'll need to use tuliptool to flash a new boot image, which you can find in this section of the forum. Then, you could either install TWRP through fastboot or using tuliptool.

Thank you sir I appreciate it I shall try it tomorrow.

here's a stupid question.... I have only dealt with Samsung devices so, I have trouble understanding any other kind of process that is not Samsung. If a new update comes out while my device is bootloader unlocked can i update it? or will it brick my device?

The "standard" (not Samsung) method of updating via OTA is to ship:
1. Full images of any firmware partitions (rpm, tz, aboot, etc.)
2. Full image of boot.
3. A delta (patch) to system.
Also note that custom recoveries generally do not work with vendor OTA's.
This means that if you wish to apply an OTA, you must first have stock recovery and a completely pristine, unmodified system partition. The rest doesn't matter.

Un-rootable thanks to manufacturer. What is it exactly?

What does the manufacturer do to the phone to make it un-rootable?
This quote: "Strictly speaking, when we talk about a platform as open as the Android OS, it is almost impossible for a manufacturer to make an ‘un-rootable’ device."
would suggest that most likely the manufacturer is not making the phone un-rootable. So then that would leave the OS, but my 4.2.2 KitKat has and is rooted on other devices.
So who and what is at fault here? Seems to me that if it was software, that would be easy. Find an exploit and root. But if it was that easy then all phones/devices would be rootable.
That brings us back to hardware and the manufacturer.

It is more a matter of the carriers trying their hardest to prevent us from being able to unlock/root the devices they offer and less a matter of the manufacturer trying to prevent it.. They do this for several reasons. But the main reasons are to prevent security breaches, to protect the information on their customer's devices, to prevent having to repair/replace devices that have been broken due to failed rooting/flashing/modifying attempts and to prevent us from using their devices on another carrier's network.
It is considered to be impossible to make devices that absolutely can't be rooted. They are all vulnerable in some manner, these vulnerabilities are called exploits, it's just a matter of finding the right exploit. When exploits are found, the manufacturer or carrier will patch the exploit and release an update for their devices to apply the patch.
The main thing they do to make devices unrootable is to use a locked bootloader, some even use specific hardware components to prevent unapproved software from booting.
It's a combination of things really, there is not necessarily one certain thing they do to keep us from rooting, because there are many different ways to unlock/root devices, they try their best to account for them all.

If all one click methods have failed, the only option left is to flash some kind of customized software or methods to modify parts of your boot and/or system partitions. Flashing custom software and modifying boot or system requires the device to have an unlocked bootloader.
This means that your first step is to determine whether or not your device has an unlocked bootloader. If it is unlocked, you can flash/modify the device, if it is locked, you can't flash/modify unless you find a method to unlock the bootloader, then you can flash/modify. Do some searches for methods to check your bootloader status.
If you find that the bootloader is unlocked, then you have a few choices:
1) if you can obtain a copy of your stock firmware then you can use the Magisk rooting method to modify the boot.img from your firmware to create a patched boot.img then flash that boot.img using the appropriate flash tool for your device brand.
2) if you can find a copy of TWRP custom recovery for your specific device model number you can flash the TWRP file using the appropriate flash tool for your device brand.
3) if there is no TWRP for your specific model number, you can build your own version of TWRP if the necessary resources are available for your specific model number.
4) if the necessary resources to build TWRP for your specific model number are not available, you can try finding a TWRP for a similar device with the same exact CPU that your device has and port that TWRP to be compatible with your own device.
Do your own searching and researching about each of these options, the more you read about them, the more you will understand.

Can't get past "Waiting on devices" when using
Code:
fastboot oem device-info
.
Device manager shows the phone is connected just fine.
The phone has no manual way to set fast boot, whether it be the buttons or entering numbers on the keypad.
Device recognized.
Code:
fastboot devices
returns nothing. I guess that means it's not in fast boot mode.
Code:
adb reboot bootloader
and
Code:
adb reboot fastboot
only reboots the phone.
On the other hand,
Code:
adb reboot recovery
does work.

Your device probably doesn't even have fastboot mode, some carriers remove fastboot from their devices, especially MVNO(subcontracted) networks.

If you're asking about what was said about not having fastboot, it is a lack of software, as in, the software is not even there.
If you're asking if the software can be bypassed, it can, the trick is to find the right exploit. That is the problem, a working exploit has not been discovered for this device.
Without fastboot, there is no way to flash custom files such as TWRP or patched boot.img. This means, the only chance of rooting the device is if one of the one-click universal rooting apps or universal PC rooting programs has an exploit that just happens to network on this device.

Have any fastboot-less phones in the past been rooted?
If so, do you have any recommended reading as far as exploit hunting is concerned?

Mandatory unlocked bootloader for rooting?

Hi everyone.
I'm thinking in buying a phone from CAT (CAT S42) and I'm not sure if I can unlock its bootloader. But I've seen on another forum that the CAT S31 has root available for it through Magisk, and I didn't see anyone mentioning having unlocked the bootloader. S42 has a MediaTek chipset and S31 has a Qualcomm chipset, if that helps.
So my question is: is unlocking bootloader MANDATORY to root a device? Can I just run a custom recovery, root the phone with that, and then the recovery gets overwritten on system boot? Or can I root through USB debugging without even needing custom recovery?
The CAT S31 I mentioned was rooted with Magisk, and as I said, I didn't see anyone talking about unlocked bootloader. But I also read Magisk changes the boot partition and the bootloader checks if it was modified. So I'm a bit confused with this too. It's also written that MiracleBox was used and I'm not sure that's the reason that I'm getting confused or not (I had never heard of this tool until now).
A set of software for obtaining ROOT privileges.
Driver_Qualcom_m.7z (9.27 MB) [link]
Enter HS QDSLoad 9008 mode from Vol + and Vol- off state and connect without releasing to USB
MiracleBox [link]
The Boot image is processed on the phone by the Magisk manager, then uploaded to the phone using Miracle again from the computer.

How may they have done that?
I'm sorry, I don't understand a lot of the root requirements part, since I was lucky and my 1st phone had the bootloader unlocked alreaedy for some reason and the second was as easy as writting a single command. But about this phone there's almost nothing and I'd like to know the general about this. If it's really necessary to have the bootloader unlocked, for example. And if it's not, then what methods can I use with it still locked?
Thanks in advance for any help!

Hello DADi590,
Unfortunately I can't answer all of your questions about S42. I have one of them and I am also looking for and confused with root procedures. But I can tell you that unlock boot loader was just a matter of get developer options on (tapping version # 10 times), and inside you can toogle lock/unlock bootloader...
How to root it safely is what I do not know yet.
good luck!

@DADi590
Rooting the Android OS of a device in practice is nothing more than adding the su cmdlet known from Linux OS to the Android OS. To root Android OS in no case requires device's bootloader must get unlocked to do so.
FYI: The bootloader of an Android device is comparable to the BIOS of a Windows computer.

Actually, after some time I decided to leave CAT alone and buy a Blackview one. If I'd break the phone, at least it wouldn't be as expensive as the CAT S42 (I bought a BV9500 - not Pro or Plus, the normal one).
Since then (with help of adventures with a tablet of mine) I've learned some more things. One of them I was suspecting and was now confirmed (thank you @jwoegerbauer) which is to root the device, just a binary file is needed to be on the correct place: su. I didn't know it was on other Linux OSes though. Interesting!
So the idea is that just a recovery must be installed to root a device. That's it and nothing else, I believe. To install the recovery is the part where one might need to unlock the bootloader - or not, if the chipset manufacturer left a tool to write partitions directly, like MediaTek or Rockchip. On these 2 it's possible to write partitions directly with a locked bootloader (this means the bootloader on my 1st phone was and still is probably locked - like my BV9500 one is, and I flashed various partitions on it already, one of them, a TWRP recovery).
This explanation is for anyone else like me who would have this question. Bootloader is just to flash partitions and I think run modified ROMs too, but not too sure about that (I never use custom ROMs). [Btw, if I said something wrong, I'm happy to be corrected!]

I believe I asked this because I prefer that it's not required to unlock a bootloader to do stuff. If you screw the phone somehow with the bootloader locked and there's no tool to flash partitions on it and you must be on fastboot with an unlocked bootloader or whatever, you just bricked the phone. And I'd prefer that not to happen. That's why I chose to buy phones that don't need me to unlock the bootloader to do anything on them. That might mean I can't ever brick them (at least I never bricked my 1st phone with the various things I did on it which I later found out not being recommended at all XD).

I've unlocked the bootloader on my Cat S42. Can be done.

Anyone managed to root lg k51?

I can't find anything definitive about whether it's rootable or not

Same here i tried every root app possible and failed.

simple , go to about phone and try to find build number,
after you find build number tap on it until it says you are in developer mode
after that head on to developer option (it may be inside about phone section or above about phone section) turn on the option which says allow oem unlock. then,
just reboot to recovery mode either by pressing volume up or volume down key with power button.
after you enter recovery connect usb cable and open command prompt in pc and make sure that lg device drivers are installed on your pc also make sure you have adb and fastboot installed.
ok, after all this type command
adb devices
if any thing shows us then you have successfully connected your device.
after it type
adb reboot bootloader
then your mobile should restart and show fastboot mode in screen
type command
fastboot oem unlock
and done your bootloader is unlocked.

I doubt that's going to work, but let me know if it does. Carriers and manufacturers use a variety of sophisticated security schemes like requiring lengthy codes that only they can provide, etc to purposely make it very difficult to unlock bootloaders. Tmobile gave me a K51 for free. They apparently feel the have to pay for it by spying on me. I bought a moto g7 plus unlocked for $117 directly from Moto and put Lineage on it, no gapps Would love to use thie k51 though if anyone figures it out because it's more waterproof and bigger battery.

Whether device's bootloader is unlockable / device's Android is root-able or not you easily can find out by means of ABB:
Code:
adb shell "getprop ro.oem_unlock_supported"
If returned value is 1, then it's supported otherwise it's not.

Absolutely no of the crap above works at all in any capacity especially sprint. Generic postings like hold volume down and power also doesn't work to go into fastboot so if you guys are following the advice of some of these guys don't because you'll drop more money on a new phone then you will unlocking it some variants verizon is one I think you have to call LG I know I spent 6 hrs on the phone with "tech support" aka "jokes with a screen to read from" to FINALLY get into touch with an engineer who told me the only way "NOW" to unlocked the bootloader is in his office which means it has to be depot to be unlocked which as of this moment lg is not doing that WILL change in the future that was 12/03/2020. Even running external adb with kali linux to hack it broke the bootloader and sends you into an infinite reboot loop

This returns no value on a locked bootloader because even with Dev. Opt. Enables its still read only until bootloader is unlocked this is verified on two carriers k51's sprint and att. However it is unlockable we haven't found it and/or LG has not added this service to their site which is where you will get the info needed for the unlocked.

Oh my. You know you need to do all this from a computer, right? Can't do it in an Android terminal because fastboot commands are only valid in a phone's bootloader environment. And if you didnt know that then rooting and all of the dangers that come with it just isnt for you. But yes, it's rootable. So here you go anyway.
Reboot the phone to download mode.
Install LG's K51 usb drivers, and install adb and fastboot, on your computer.
Open a command prompt and type: fastboot oem unlock
If it does anything other than pat you on the back and tell you it's proud of you and how well you follow instructions, then go back and follow the effing instructions.
Otherwise, type: fastboot reboot.
Download magisk manager.
Do the magisk manager.
Use the LG flash tool on your computer to flash what you just did when you did the magisk manager.
And presto, you're rooted. Or I successfully left out enough info and you dont know how to use Google, leaving your device still not rooted. And thank god for that.

Ive been learning from xda for some time now. Bricked a few phones in my learning curve and tonight i had my first success with my g7, and wrighting this on my new k51. This is my first post and I think that was pretty rude of you to say. This is supposed to be a place to learn, share knowledge, and help those who are less educated. Not look down on people and say crap like that. If he wants to learn even if it takes a couple bricked phones to do it, let him. Either give him the proper procedures or dont say nothing at all. How long did it take you? How many phones? Its taking me quit a while but i am finaly getting somewhere. Keep with it guy. Dont let this dude, or any one else for that matter, bring you down.

Yo Ken,
So your K51 rooted?
If so, maybe you could provide a step by step?

I haven't done this yet but is it verified working? I did a google search came across the method to do the unlocking but it showed it was a failed project?

O lord i hope this isnt true

Can you help me? Trying to get my phone setup

I recently got an LG V20 on AT&T from a relative, he gave it to me because the previous owner passed away. I managed to factory reset it, but there's one problem. At setup it tells me to sign in with the previous owners account. I am unable to do this as said previous owner has passed away, is there anyway around this? I suspect the phone is on Android 8 at least as my last V20 was. I also assume it's on a security update from summer 2020 as that's when the person has passed away
