[TOOL] One-Click bootloader unlock (no root required)

I've made simplier way to unlock the bootloader of ZE551ML/ZE550ML.
Update! Version 2.
Now it's not required to flash/downgrade droidboot.img. But you still need to flash one of compatible ROM.
Currently compatible versions are:
For ZE551ML: v2.19.40.18, v2.19.40.20, v2.19.40.22 and future newer versions unless opposite mentioned.
For ZE550ML: v2.19.40.12, v2.19.40.13, v2.19.40.23 and future newer versions unless opposite mentioned.
For example, you can flash full ROM v2.19.40.22 and then use unlocker v2.
Just unzip everything from attached archive and then start unlock_one_click_v2.bat
If you've enable USB debugging then phone will automatically reboot to bootloader and will unlock the bootloader. If you didn't enable USB debugging, then you need to reboot to bootloader manually (Turn the phone off and disconnect USB, then press Power+VolumeUp keys at the same time and keep it pressed till you see ASUS logo, then you may connect USB cable).
Either way, unlock_one_click_v2.bat will proceed to unlock in fully automated way.
If initial boot splash screen become inverted, then bootloader has been unlocked!
If you don't like white boot screen, then you can flash original black one:
http://forum.xda-developers.com/zen...-black-white-splashscreen-twrp-flash-t3141945
Originally, it's developed for WW firmware but should work on any region.
Works on CN firmware. Confirmed by @corrsea
Based on unlock method discovered by @shakalaca
Based on fastboot hack by @social-design-concepts

Version 1 (old)
To use this version, you need to flash ROM not older than v2.19.40.18 for ZE551ML, and v2.19.40.12 for ZE550ML. And then downgrade (if required) droidboot to compatible droidboot.img
Code:
fastboot flash fastboot droidboot.img
For ZE551ML, known compatible droidboot.img versions are 2.19.40.18, 2.19.40.20.
For ZE550ML, known compatible droidboot.img versions are 2.19.40.12.

Important note for Stock ROM lovers:
Although, unlocker v2 works with v2.19.40.22, there is no warranty, it will continue to work on future versions. It is up to ASUS decision. Unlocking process still requires several files from /system partition including special version of if.bin (/system/etc/firmware/if.bin). These files are still supplied with v2.19.40.22, but in the future they can be removed by ASUS together with disable of downgrade ability for if.bin.
So, if you will flash future stock ROM through official update procedure (which includes bootloader update - from ifwi.zip) then you may loose unlocked bootloader! And of course, ASUS may completely block unlocking procedure (at least unofficial way).
So, if unlocked bootloader is important for you, then
1) unlock it ASAP while current firmware allows.
2) don't use official updates. You need to remove all lines from update script containing ifwi.zip references and then flash through TWRP (you need to remove lines checking recovery version as well).

thank you very much for making this way easier, hope it will help many people, good job bro

@sorg, thanks for the tool. One ques. Will it wipe off the data? And does it keeps OTA taking ability or will it break off? If it breaks, what can be done to get it back?

Hi
Is there anyway other than installing a third-party recovery to verify if the boot-loader is unlocked or locked ?
will it void warranty of the phone.

If you unlock the bootloader it will void the warranty, as there's no way currently to lock the bootloader again.

Are there news for the ZE500CL version?

I currently have .22 via OTA, so I can just proceed with unlocking the bootloader without any issues? because in the other thread, they are still saying there is no way to unlock bootloader without downgrading to .20 or .18.. TIA!

man, a simple "yes" would have been easier to type and more polite.. of course, I've read it, same with all the threads here.. that's why I've seen a conflicting statement in the bootloader thread, hence the attempt to "clarify".. not everyone here is as good as you are.. thanks anyway..

great tool ! thanks

So im on v2.19.40.22 and ran Version 2
Phone rebooted went into stock recovery but it did nothing on there. The prompt on the PC said it was unlocked.
I manually rebooted my phone and the splashed looked the same.
Did i do something wrong?
Am i unlocked?
Can i verify if it's unlocked?
Thank You for you help.

Hello,
I am a little confused by these 2 lines.
The first line says:
But you still need to flash ROM not older than v2.19.40.18 for ZE551ML, and v2.19.40.12 for ZE550ML.
The second line says:
For example, you can flash full ROM v2.19.40.22 and then use unlocker v2.
So do I need a ROM no older than 2.19.40.18 or does 2.19.40.22 works fine?. As far as I know. 2.19.40.22 is older than 2.19.40.18.
Please clarify for me.
Thanks
Jeannette

V1 for anything under x.20
V2 for x.22
I think this is what it means but i may be wrong. Flash at your own risks

Why don't you say which rom we can use instead of which we cannot.

Because I've made unlocker not for one specific ROM version, but for any existing starting from .18 and newer.
.18 is older than .22, where is confusing?
I understand, that we live in time of smart phones and stupid people, but try to be on par with your phone at least. I've tried my best to explain in the OP what ROM versions you can use. I've made some bold text, some red text to take some attention. I've wrote example especially for .22 version! If it doesn't help, then i don't know what else can i do. How .18 cannot be obviously older than .22?

I've updated the OP, wrote compatible (as of today) versions. If even this is not clear enough, then i give up.

Awesome Work Mate. U ROCK!!!

No IMEI, bootloader locked, no root, no sim working

Hi,
I have an EU G7 L01, followed this guy's tutorial (http://ministryofsolutions.com/2016...ade-marshmallow-europe-asia.html#comment-2438) to update to marshmallow, replacing the "oeminfo" file with a turkish version, to trick the phone into updating. The new file had no IMEI in it, and after the update I was left with a locked bootloader, no root and no way to replace that file with my backup, to make the phone accept the sim card. From what I see, I'm either left with a small tablet or I have to replace the motherboard to make it work again.
Any other ideas would be appreciated.

To get your device to its original state, you need to downgrade to B340 of the Turkish firmware: http://download-c.huawei.com/download/downloadCenter?downloadId=74865&version=273720&siteCode=tr
Do a forced update with B340, root the device using Kingroot, replace your original oeminfo file, then install the official EU firmware.
If you really want to use marshmallow, then the only way will be to pay for your bootloader to be unlocked. On the source post, it clearly states that there was a problem with unlocking the bootloader, and HCU Client should be used to unlock it. The problem with that guide is that the bootloader unlock code only works a certain amount of tries before it becomes unusable, and the only way to replace your original oeminfo file is to have root, which is only possible on marshmallow with an unlocked bootloader.
I would suggest you let the guy who wrote the article know about your issue. Regardless of whether he stated that it is done at your own risk, he either needs to amend his article to that of the source, or remove it completely, as many people will not be able to pay $5 to get the bootloader unlock code.
Good luck!

A2017G (6.0.1) B08 - Root without Unlocking possible?

Hi there,
I found there is a thread describing how to root the US/Chinese model without unlocking the bootloader -
https://forum.xda-developers.com/axon-7/development/wip-axon-7-root-bootloader-unlokced-t3441204
However it mentions that this'll brick the European model because of the included TWRP version and unfortunately I'm on a ZTE A2017GV1.0.0B08 (Android 6.0.1, Kernel 3.18.20).
Is there any news if this can be done now with the international variant -
I'm not interested in a custom ROM or updating Android, I'm happy at the moment with the 6.0.1 version I have, but really would like root for xposed framework, Titanium, Tasker ...
Is there a different TWRP version that can be used or is it not working due to the ZTE's signature key used?
Alternatively is there a way for the A2017G to re-lock the bootloader that's 100% working/safe, if you don't apply a custom ROM?
Thanks a lot for your help!

Hi.
It didn't really answer the question : Is unlocking necessary to root, or can we root without unlocking ?
Every tutorials founds all follows the same paths : Unlock first, then root. But why ? is there a reason for that, or is it just a "since i'm rooting, let's unlock it while i'm at it" thing ?
(edit : Sorry 4 my english ... i hope i've been clear enough)

Hallo Marcus
Danke fuer die Antwort -
Maybe I didn't fully comprehend the thread - I was under the impression that it bricked some A2017G, while not others and didn't want to take the risk.
Reading through the instructions - which of these steps did you take (and in what order)?
I read it that you do not need to flash TWRP? So can I just root the phone without bricking it and all is good as long as I stay with my 6.0.1 B08 version?
I understand the instructions as
- boot into edl
- install Qualcomm driver
- run axon7root to already root the device (backup seems to be done in the next step?! according to instructions).
However there is no axon7root version for the A2017G (B08) as it was removed due to TWRP?!
All I can find is the axon7backup tool (would you actually do this before you run the axon7root the first time?)
If you run the axon7root, did you do 'axon7root.exe -p 4 -b'
so that it only flashes the boot.img (not TWRP recovery) and therefore this is safe?
Sorry for the long essay, help is really appreciated!

Hey, sorry for the delay.
I am quite busy. I really don't know the procedere anymore. It is a long time ago. But if you would give me some time, I will have a look on it and will let you know. But why won't you unlock your bootloader? Without unlocking not everything runs as it should with unlocked BL.
OK. I will let you know.

Theoretically, yes, you can root w/o unlocking the bootloader. This is how things are done typically with certain manufacturers (LG, Samsung) that rarely offer BL unlocking. To be able to flash TWRP on a locked BL is even more difficult, as it would require a BL-level exploit. The reason that's not an option here is the ability to unlock, which precludes such development.

Hi Marcus,
Thanks a lot, that would be really great.
Regarding Bootloader unlock - I didn't buy the phone in the EU, hence my warranty would be void if I unlock it. And my warranty even comes with screen replacement (not that I ever cracked a screen, but there's always a first).
I have to admit that I'm tempted by Lineage OS, but for now (as I just bought the phone) - if there's a reasonably safe way to root without unlock, I'd prefer to just root and then maybe in a year's time or so switch to Lineage OS...
For now I managed to have my phone recognized as QUSB_BULK and I can boot into edl.
I was trying to use the axon7toolkit (1.1.1), but for whatever reason I cannot use it in commandline mode (maybe as there seem to be different versions, or maybe cause I am on Win7 32bit, no idea).
Any help would be really great!
Hi jeboo, Hi Sn8k,
Hope above explained my motivation, regarding root without unlocking - there's a thread about this
https://forum.xda-developers.com/axon-7/development/wip-axon-7-root-bootloader-unlokced-t3441204
HOWEVER there are two problems:
1) The bootloader can stay locked as it's using a signed version of TWRP, which can brick your device (A2017G)
2) The linked axon7root.exe is not for my device (A2017G B08).
Having said that, some users have been successful with rooting this version, so there seems to be a way, if you get the steps right.

You can't. Don't even try it if you don't want to face DFU...
Just use the same app that the phone comes with, I think it's WeShare or something like that. It should let you transfer all of your crap via a LAN wifi transmission (If you use a 5GHz hotspot it'll be fast as heck).
Or just unlock the phone. But don't relock it if you do, because you can make a huge mess

[How to] flash Global to China Mi6 without UBL

I bought the MI6 and find out that without tools or unlock bootloader, there is no way to flash a global rom to china rom. My Mimax convenient EDL cannot be used in Mi6.
Unlock is easy, but since mine is new and under warranty, i prefer a Xiaomi rom.
Luckily i fond this tool:

Credit to the dev http://en.miui.com/forum.php?mod=viewthread&tid=663972&highlight=xiaomitool
Download this, run, and follow the screen.
it will check your boot, recovery, then list the rom that possible to install.
Choose global, lets it download, choose recovery and the tool do the rest.

Thank you. I will give it a try on " bricked" mi5 and new mi6.

This tool make unlock bootloader automatically... so your warranty is gone after

Just ask for permission to unlock bootloader, usually takes a week or so. Unlock > flash > lock again. No need to experiment with some tools or whatnot official.

I already had been using the phone for long enough, the permission took 4 hours to go through. Never been an active user of their services either.

Actually I am looking for a way to wipe whole partition as my second-hand mi6 is binding with a mi account which is not mine.
Flashing in EDL mode is easy to flash any official from you want but asking to unlock the device after setting up.
Though there is some tricks can be done to bypass the checking, I cannot log on my mi account or even restart device.
I had just had a tried as this thread: https://forum.xda-developers.com/mi-max/how-to/installing-twrp-locked-bootloader-t3406501
To flash TWRP directly by MiFlash. But fail to boot in it with a 'the system has been corrupted'.
Just wanna give more ways to flash or unlock with the limitation of officially unlock BL

Look and unlock bootloader with official method

In other posts there is procedure , for device with bootloader unlocked with unofficial method, for look and unlook officially, but is confused and in other arguments.
Is possible have this post for this argument, with clear guide , because I think is important question.
This maybe procedure:
1. miflash to official China Beta rom first. Flash without relock.
1b. Download from PC VPN app, install on phone and set connection to China. Then you are able to active usb developer options
2. re-lock bootloader with official China Beta rom. Flash and relock.
3. unlock bootloader again with official China Beta rom. Need to tie up with Mi account and insert a SIM card. For me, need to wait for 720 hours before MM3 can be unlocked. I checked chinese miui forum. This apparently is a new requirement. One full month later. Gosh...
4. miflash to official Global rom and stop there.
5. Do not re-lock bootloader with official Global rom""
I don't try this procedure......

What's the point of looking the bootloader just to get it unlocked again after whatever hours waiting!?
Do you experience problems with the device being unlocked unofficialy? Or this is just another "good advice/info" coming from MIUI forums...
Be happy somebody already took care of that and enjoy the unlocked bootloader freedom you get.

The device comes unlocked but your Mi account has not permission to unlock this specific device because you never followed the official unlock procedure.
Xiaomi with its new policy does not let you use a Chinese version of a phone with a global rom and a locked bootloader. If you flash the global rom and for some reason the bootloader gets locked, your phone will stuck on the recovery with the following message "this miui version cannot be installed on this device", at this stage you must unlock the bootloader to be able to boot again, if the bootloader was unlocked officialy with you own account, you can use the mi unlock tool to unlock again and make the phone bootable, if the bootloader was unofficialy unlocked or unlocked by other account, in this case you can't unlock with the Mi unlock tool, you can't flash another rom since the bootloader is locked, you can't follow the official unlock procedure because you are stuck in recovery, the only solution is to use the test point method with EDL authorized account

Ok, I guess sounds reasonable for majority of the users.
But me personally? I could care less...
You can backup bootloader unlocked status and restore it if locked by accident...

As far as I know, EDL mode is locked on newer xiaomi devices.

It requires either root or EDL or TWRP...
And no, EDL is not locked, it's not Xiaomi's feature to lock it, it's Qualcomm business... MiFlash is locked which is irrelevant... Who needs their stupid front end when you can use Qualcomm tools...

Quote from the link a gave you
Users have been experimenting with older versions of MiFlash as well as Qualcomm's official flashing tool QFIL, but to no avail, they couldn't flash in EDL because the programs could not bypass the requirement for authentication.

Is this irrelevant?

Maybe, we are not talking QFIL and flashing roms here. Will let you know when I get my Max 3 and test it.

your help is highly appreciated

The device comes unlocked but your Mi account has not permission to unlock this specific device because you never followed the official unlock procedure.
Xiaomi with its new policy does not let you use a Chinese version of a phone with a global rom and a locked bootloader. If you flash the global rom and for some reason the bootloader gets locked, your phone will stuck on the recovery with the following message "this miui version cannot be installed on this device", at this stage you must unlock the bootloader to be able to boot again, if the bootloader was unlocked officialy with you own account, you can use the mi unlock tool to unlock again and make the phone bootable, if the bootloader was unofficialy unlocked or unlocked by other account, in this case you can't unlock with the Mi unlock tool, you can't flash another rom since the bootloader is locked, you can't follow the official unlock procedure because you are stuck in recovery, the only solution is to use the test point method with EDL authorized account

that is exactly what just has happens with me few minutes ago.
I bought the MAX3 through Ali Express with "fake" global Rom, and open bootloader, however since the global ROM is officially released by Xiaomi so I was trying to flash it through XiaomiFalsh but, mistakenly, and unfortunately, I kept the tick mark on "clean all and lock" and now the phone is stuck on recovery, I called the service center of Xiaomi by they said since it is not officially announced in my country so it is not their baby and they asked me to contact the seller "who ali experess! no way!!"
guys who can help me to get out of this issue will be really appreciated, but keep in mind I'm not an expert.
awaiting your kindness

Apply for unlock bootloader here: https://en.miui.com/unlock/
Wait time is 720 hours. No other way around it. Sorry, buddy.

There is no way to apply for unlock without a bootable phone, He must go to Developer options -> Mi Unlock status -> Add account and device but this is not possible because the phone is stuck in recovery.
The only solution right now is to use the test-point method to flash the chinese rom.

Someone I helped fastboot flash China 8.8.9 mistakenly did this and was able to boot. Is Global rom entirely different in this situation?

Yes, it's different
chinese device + global rom + locked bootloader = stuck in recovery

Oh right, now I remember. This was that very big announcement. Completely forgot. Thanks for the reminder. Yes, then test point is the only option, unfortunately.
Again, this was why I urged people to steer clear of global and stick to Eu roms. More harm than good especially related to such situations (many new flashers accidentally locking bootloaders).

Thank you so much guys for your feedback, for now I have the flowing questions:
1- the phone is stuck in recovery mode, how I shutdown the phone.
2- If I wait for Xiaomi to launch MAX3 officially in y country do you think they will be able to help me even with charged service?
3- can any of you expert guys direct me to some useful link to see how do it use the test-point method.
4- If I succeeded to unlock the bootloader through the test-point method, is it mandatory to flash the Chinese version or I can flash global Rom and keep the bootloader unlocked.
thank you in advance for your time.

1. Hold power and volume down until boots to fastboot mode, leave it and it should turn off automatically after few seconds.
3. You can find some information scattered to the following threads

4. With the test-point method you can flash the chinese rom even if the bootloader is locked, after succesfully flashing the china rom you have to apply for official unlock, after getting the unlock permission you can flash global rom by leaving the bootloader unlocked.
XiaomiTool official page is proposing another solution but you need to wait for a global dev rom to be released and it is not guaranteed to work
If you get the message "this miui can't be installed on this device" and your device is bricked you might be able to recover it using xiaomiadb by first installing global developer and then installing china developer OF SAME VERSION (for example 8.8.16->8.8.16) using "xiaomiadb sideload_miui -otarom CurrentRom [ZIP_ROM_FILE]"

hello all, if someone can help me, i have my mi max3 with locked bootloader.
now i dont have any rom on it so trying to load a rom but getting an error ERASE is not allowed in locked state
what rom can i flash on it ?
tried to unlock bootloader via the tool, it gets stuck at 50% cannot verify phone.

had the same problem, was able to recover it with the test point method and flashing chinese rom, and switching to english language.
the procedure is described here:
https://androidfilebox.com/tips/edl-test-point-mode-redmi-note-4x/
the installation process of the qualcom drivers is special.
you have to open te backcover, which is very special too, dont forget to the 2 mini screws at the usb port and the drawer on the side . search and look on youtube.
look further, where the testpoints are on the mi max3
follow strictly the procedure, load and double extract the chinese rom for the mi max 3.
It is real work, and real danger that you break something mechanical, one shoud have a calm hand and a lot of patience, but for me all went good and the phone spang to live again.
Another solution could be this, but I have no experience with it:
