Bootloader Unlock Tip

Hey All,
I've seen some posts stating that the bootloader for this phone can't be unlocked.
I'm using the E6533 model and wanted to confirm that it is possible.
Just go to this website: http://developer.sonymobile.com/unlockbootloader/ (the official sony one)
Select Xperia Z3 as the model (I know we have the Z4/Z3+ but it still works). Enter your email and click the link they email you.
Insert the IMEI number and they will give you the unlock code. then just run
adb reboot bootloader
fastboot oem unlock <code>
and it will work.
As a note this WILL wipe your device, so backup anything you may need on it.
Hopefully with this we can get root / twrp built

So TA backup is needed to keep the DRM keys before unlocking the bootloader. Is there a way to back up TA of non-rooted devices? Flashtool doesn't fully support Z3+ yet.

help
Quick question , what to do if you have Unlock allowed: No?

Generally speaking this always meant just what it says... That it's not possible to unlock the bootloader. This was often the case with oem phones. Today it could also mean you have myxperia security activated. If you have log out of that and try again.
Oh and do not activate it after unlocking bootloader, you could brick your device for good!

Make sure you don't have the xperia security software enabled (the find my iPhone equivalent)
It prevents the bootloader from being unlocked. Otherwise it means your carrier disabled the feature

Thanks diemadedrei and ChrisJ951.
It worked, it was the Xperia Security software that was enabled.

Rooting status: unknown
Hello, i tried to unlock my BL from the sony website, but after i flashed the code in my phone, it just restored and now just says rooting status: unknown and also the option of unlock allowed does not even appear! anybody could please help me?
thanks and hello from Mexico!

The z3+ is now selectable on the unlock page officially
@bryantronics: it should say bootloader unlocked yes under rooting status. Generally it should have worked if everything went as described.

Thanks to all, I have tried to change it to "YES" 24 hours

OK so with this recent tidbit of data that a bootloader unlock no could become a yes I am concerned. When I bought the phone it said yes. But no where can I figure out if the DRM keys are a)original b)intact c) working with this present rom. Could anyone tell me so I can be sure that if I resell this item I don't misrepresent this information.

haist i have a same problem for that issue ...until now i can not flash boot img...please resolve this problem...guys plssssss......

i have the same problem i cant flash img due to remoted lock state: unlocked

any updates?
I am suffering the same problems as my colleagues in the previous posts. I cannot get the bootloader unlock, no matter how hard I try:
performed the official Sony way (using minimal adb and fastboot; phone is listed in fastboot devices; "remote: command not allowed")
flashtool64: both with blu manually and by leaving the text file in the registered devices folder (which was found and used for a unlock, which turned out not to be successful).
Sony MyDevices is not activated. Android 5.0.2 (E6533; 28 0 A 8 272 HK)
Do you have any further tips how to open the bootloader?
thx, Benedikt

hi
How long does it take to unlock ? the bootloader. I've waited for long.

Unlock bootloader NO
Any solution

i was crashing my head to do it and nothing to it done, and I discovered that the problem was that my xperia was enabled, so I disabled it and finally unlocked the bootloader

I had bootloader unlock allowed: no on latest firmware. I backed to Android 6 a I have bootloader unlock allowed: yes

Booloader codes available now !

Good news. You can now get your bootloader code without waiting 14 days. Just buy it with DC-Unlocker here : https://www.dc-unlocker.com/

So you are basically paying for a software to get you the code and uninstall it...

You have to put your device in bootloader mode (switch it off, plug it to your computer, and press Power + Volume down at the same time). Once you're in DL mode, enter the command "fastoot oem unlock xxxxxxxxxx" xxxx = your code.
Before you do this, enable "OEM unlocking" in Developer options.

So by following above process and bootloader unlocked means you're rooted? (sorry for the dumb question, I am not an expert)

No by following that process you will have an unlocked bootloader enabling you to install custom recovery and then root. Follow this thread and the instructions for unlocking your bootloader, installing TWRP, and then rooting your phone.

Confused with how to order this thing. It talks about credits?? Also is the program a Windows program? Only?

Is the program compatible with MHA-L29? I can see the MHA-L29B on the website, but I would like to know if it will work for mine. I mainly am concerned with the relocked to locked option of the program

from my past experience with them, you do not need to use their software, once you have the unlock code you are good to go.

[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:
https://drive.google.com/uc?export=download&id=0BwypTnSm1wlhTkp0ai1LUXZKdkk
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

Did it work on Mi5? I would like to flash my Mi5 with locked bootloader
Ok it works

It is not working locked bootloader

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...

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...

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.

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.

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:

Unlock bootloader?

I tried everything to unlock bootloader in Black shark 2 Global Version i enabled OEM unlocking on the developer options and then tried fastboot flashing unlock and fastboot oem unlock with adb, and the "error says unlock is not allowed on device has sales on market!", we need to unlock the bootloader there is a post in this forum who have patched the boot.img, so if the boot.img is correct unlock the bootloader is the last step to finally root the Black shark 2.
Any ideas?

There's a link to a forum about the black shark 1, where they encroached the same issues, error message you've described. A user has included instructions on how to bypass/get round it with photos in the post. But it only worked with the global ROM. And it's a different devise but might be worth looking at if you want as much info as possible that might help.
Before you do anything an brick your devise tho, I would recommend an air of caution.
I will pm you the link because I don't know if linking other sites is against the rules of the forum
