Bootloader Unlock Tip

ChrisJ951 · Jul 25, 2015

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.

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

diemadedrei · Aug 6, 2015

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......

artsfreaky · Feb 8, 2017

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

beneedict · May 22, 2017

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

Thanks for the tip but how I can back up TA Partition? Can you help me about that? And I am using latest Nougat Single Variant E6553, your tip will work with nougat?

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
