Bootloader unlock on A2017 chinese version?

I want to buy this phone from spemall,and i readed the us and europe version is unlockable but not so much info on the chinese version.It's also have oem unlock option and require 4 digit pin code.I read one guy able to unlock it on port 9008,but its not so much info about it.
So somebody knows how to unlock chinese version in proper way?

Any progress? Still trying to find the proper twrp recovery file to flash but no luck as the ones I can find are giving me a black screen. The one in the other forum is a dead link so I am waiting for it to come back so I can try flash that :/ I am trying to bootloader unlock and also try flashing either nougat a2017U and also a2017G since I don't like the Chinese rom.

Any chance to flash a custom rom to my newly purchased Le Pro3 X720 with EUI 5.9026s?

Hi all,
Recently, I go through this forum and found there are many custom roms ready for this Le Pro3 phone. After consider the hardware specification and cost, finally I procured Le Pro3 (x720) phone.
However, when I received this phone, I found the latest EUI already installed (EUI 5.9.026s). When I go through the instructions provided by XDA forum, I found there almost no way to unlock the bootloader of this phone if this came with EUI 5.9.026s.
Can someone tell me if there is a way to unlock this bootloader if this phone is came with EUI 5.9.026s? If not, can I still can refresh my phone with some custom roms (like Omni rom on lineage OS?)
Thanks

I have no trouble with my x720, first time flashed customs on 20s, but few days ago returned from stock 26s to custom. Can't you unlock your phone?

No luck on unlock.
I believe you already installed TWRP before upgrade to 26s, so you can falsh back to previous version.

Have you official ROM and followed the unlock guide?

I follow the unlock Guide but no luck. I go through few discussion in XDA forum, seems some major changes in OS permission settings on 26s rom

Maybe flash 23s, wipe then try?

I cannot try it, but maybe it's possible to fool the update system. By modifying the update script of a 23s OTA file you can bypass the check for rom and modem version, then the system will execute a "downgrade" from 26s to 23s. This theorically, I can't try if it really works but the right path can be this! Cheers!
Sent from my LEX720 using XDA Labs

I did downgrades from 20s to 18s and from 23s to 20s... Seems buggy, but after wipes worked perfectly.

@marik1
How did you do the downgrade? Is the way you downgraded possible with a locked bootloader? Thank you.
(I am considering buying a Le Pro 3, but I will probably wait until I know that unlocking the bootloader is possible with the new EUI installed.)

For me it's simply flashing file with ROM called "update.zip" and placed into main folder trough LeEco's recovery. Like making update, but with different file.

I tested qfil by following the thread here to flash the previous rom but no luck, when I use qfil, I am quite sure the phone is connected ( I can see the com port), the process started(rom are unzipping), but when the system try to write on the disk, the process failed. I wonder if there are any permission/encryption settings applied on the partition of 26s rom, and not sure if I can downgrade due to partition permission.
BTW, where can I download 23s rom? and how to modify the script to prevent version check? thanks

Where to download this file? and the file should place on main folder but not root folder, right?

Just flash it, without changing version checking. You can take it from LeEco website;
https://bbs.le.com/zt/eui/le_pro3.html
You can also have trouble with connect, so you have to remove :110 from link and you gain;

Developer options，unlock OEM

Can someone confirm that unlock works for new devices which are shipped with the new software version? @andylcm please let us know if you get it working. thanks

the problems have been fixed.
Actually, I follow the unlock guide here, the problems was on this bootloader unlock guide but not on the phone itself.

@andylcm
Could you please explain what you did differently from the guide?
Is this the guide you are referring to? https://forum.xda-developers.com/le-pro3/how-to/leeco-le-pro-3-root-t3476560

I know that device info command shold be device-info

Global Rom Is Now Available!

Global Rom is officialy out!
it turns out 9.6.4.0.OEDMIFD is a real global rom with a broken modem.
just update to newer releases that might fix the issue.
You cant just flash the global rom over an Antirollback rom as the global rom doesnt have Antirollback. (it will brick your device)
Guide to installing global rom on antirollback devices & installing global rom with fixed modem (for calls and internet) over china rom (no ARB): here
Download Links for Official Global Rom: here
Antirollback information: here
Thanks and have a great day!

Hello there people!
our lovely new Mi Max 3 is now available for purchase on many websites.
These websites sell you a "MULTILANGUAGE rom" or "Global Rom".
The version that they sell is 9.6.4.0.OEDMIFD
Unfortunately this rom is FAKE / Un-Official and is dangerous for your device!
Why? because to install this shady rom they need to unlock your bootloader unofficialy and install a rom which was not originaly designed for Mi Max 3! this rom bricks some partitions of your device and may cause a lot of issues later! Some say that this rom may cause damage to the ability to flash roms and more onto your device or to move to official rom / xiaomi.eu rom
THERE ISNT ANY OFFICIAL GLOBAL ROM AVAILABLE FOR MI MAX 3 YET!
I suggest not to buy the Mi Max 3 with a "MULTILANGUAGE rom" or "Global Rom". (Please notice that some people that have asked not to install the fake rom got their devices with the fake rom even though they asked!)
Be patient and wait for official global rom from en.miui.com
Have a great day!

I suggest flashing the latest china beta rom using fastboot mode
MAKE SURE THAT YOUR BOOTLOADER IS UNLOCKED
download: here
after that flash xiaomi.eu rom
tutorial: here

Why do you need to flash both the china beta rom and the xiaomi.eu rom?
The flashing of xiaomi.eu does not delete everything previously installed anyway?

Fastboot china rom will wipe all partitions and reinstall them.
Xiaomi.eu recovery rom only changes the SYSTEM partition, remember you are coming from a fake rom so you might not want to have broken partitions from the flashing of the fake rom.

My Max 3 comes with this so-called "Global" ROM.
I checked my bootloader and it says Unlocked. So yesterday I downloaded CN ROM and flashed it via fastboot.

Ok, I understand. "fastboot china rom" means it should only be installed through fastboot? or its also possible through custom recovery?

MAKE SURE THAT YOUR BOOTLOADER IS UNLOCKED BEFORE DOING THIS OR YOU WILL BRICK YOUR DEVICE
Fastboot roms are flashed through a special tool by xiaomi which can be found: here
You also might need adb drivers which are found: here
1. Open the drivers file and click "y" for every option that it asks for.
1. Install the fastboot tool tool
2. Download the fastboot rom that you wanna flash
3. Unzip the rom to a folder on your pc
4. Open the tool and in bottom right corner there will be 3 options, select "clean all"
5. Click on the "select" button on top left corner and head to the folder that you unziped, select it.
6. On your device enable "USB debugging", "install via USB", "USB Debugging (security settings)", and disable "verify apps over USB" (Developers options are enabled by going to "about phone" then spam clicking the "MIUI version" until it says that your are a developer. then go to "additional setting" and you will find "developer options")
7. Boot your device to fastboot mode by holding down the vol- + power key together until you see a bunny with fastboot sign.
8. Connect your device to your PC and click the "refresh" button on top right corner. (your phone should now appear in the list)
9. Click "flash" and wait until your device boots to the MI logo and 3 dots. (DONT DISCONNECT YOUR DEVICE BEFORE THAT!!!)
10. Wait for your device to boot up
11. Enjoy!

Hi, So if I buy with China ROM (Outside China - I live in Thailand) I can download and change to Global ROM once it's released?
China ROM will still get updates, though right?
Sorry for numpty question!

This is the ROM on my girlfriends Mi Max 3.
Thanks for the info but it would also be good if you posted up how to check if the bootloader is unlocked seeing how important it is before doing any steps.
Also you state that for the people to put on the fake ROM they had to unlock the bootloader in the first place so would they then relock the bootloader? Won't all phones with fake ROMs have unlocked bootloaders?

Check if you can install twrp, if you can its unlocked.
You may never know...

This procedure work on 128 Gb mi max 3 ?
Thank you

I ordered a one from Eternal Team on Ali before I seen this and asked them about the fake rom and the bootloader after it was sent this is the reply .....
Dear friend:
Welcome to our store . /:000
Sorry for the late reply .
It's locked . But you could use the Google play and use all the function normally . If you need use the Mi service . You need unlock it by yourself .
Please check this link:http://en.miui.com/unlock/

Thanks for the advice and I really appreciate your help but could you give some clearer step by step instructions as many people are not coming from a Xiaomi world. I come from Note4 and for me to install TWRP I do this using Odin but;
1) In simple step by step guide, how do you install TWRP on the Mi Max 3?
2). How do you unlock the bootloader - I go to https://en.miui.com/unlock/ and it starts in English then the next page is in Mandarin so not good to me.
These and other basics instructions are needed to be clearly detailed in a thread as there will be many people following me with the same questions/issues.

1. yes go: here
2. You need to create a mi account on global forums and then use them to apply, assign the account to your phone in developer settings and unlock your phone after you got perms. search for a vid on how to unlock the bootloader on xiaomi devices on YT for a better guide.

Thanks for the info.

Excellent, thanks that is much clearer.
I checked this video on youtube for checking 'locked bootloader' and also how to unlock.
https://www.youtube.com/watch?v=zL2omn9PGc4
I did not need to unlock becasue as I rightly guessed the bootloader is still unlocked. (pic attached). This is on both the Mi Max 3's that I have.
So I'll just start the process of flashing the Chinese ROM (to make sure of partition integrity) via Fastboot and then installing TWRP, and then flash the Xiaomi.eu ROM.

OK omer919, thanks to you I have flashed the Chinese MUI10 Fastboot ROM.
Unfortunately the link to the TWRP instructions is not good at the moment as the TWRP link in that thread is not working and the thread is now closed.
Do you (or anyone else) have a working link to TWRP for Mi Max 3 so I can install the Xiaomi.eu ROM?

Hello this is for asus zenfone max pro m1. idk if someone will still see this but, i downloaded the official apk unlock tool from asus how do i unlock nootloader with it?

zenfone 3 with firmware 15.04 possible to unlock?

Is it possible to unlock this with 15.04 firmware?
Maybe I need to downgrade? Pointing in the right path will be nice

Me too!
I tried official and unofficial ways and cannot unlock my bootloader. I also tried to downgrade using the files available in Asus support page, but it don't work too.
Someone can help us in unlocking in Android 8 or help us with the downgrade? All the links to stock RAW files available around here and in 10 pages of google search are broken...
EDIT:
@CharlesDicken Look at the Support page from Asus site and download the most recent Unlock Tool. (0819-1438_SIGNED_UnlockTool_9.2.0.0_200807_fulldpi_ZE552KL.apk). With this version, I was be able to unlock my Zenfone 3 and proceed with TWRP, Magisk and root in the end.
