Every Sony user knows about "My Xperia" function of their Xperia Device. It's like the ‘Android Device Manager’,which helps to find,lock or wipe your device remotely if lost or stolen. But android devices can easily flashed. Sony devices can be flashed also. So, it does not work actually.

Here comes the best part from Sony.
Existing security solutions are usually a part of the Android operating system. This means, that by swapping the operating system the security feature or application is deleted.
My Xperia Theft protection is added to the bootloader of Xperia devices. The bootloader is needed to start the operating system of your device, and it is not part of the operating system itself. So if you delete the operating system, MXTP will stay active and your device will still be protected.

How to exit Lockdown?
If lockdown was triggered you can unlock your Xperia device by authenticate as the valid owner of the device by signing in to the Google account which was used to activate My Xperia with Mobile Data or Wifi
Tap Authenticate in the lockdown screen > Enter the login credentials you used for sighing up for MXTP and tap Sign in > Wait until your account is validated.

So, you can say that Sony is the most secured android phone now. But wait...
***Here comes the Worst part***
At the time of writing this review
A lot of M4 Aqua users reported that, after 3 days of activating "My Xperia", upon reboot, the phone entered into Lockdown mode automatically. After providing the correct ID and Password the phone failed to Authenticate and remained in Lockdown mode making the phone paperweight.
It maybe due to their software bug as the function is afresh and need more testing and time to be fully perfect.
But the worst part is that, if it enters into Lockdown, you won't be able to flash it with flashtool to make your phone working again. Only Sony Customer Care can fix it. And if there is no customer care around you, you are screwed.

Theft Protection workaround
I managed to reset phone using companion tool and after that my username and password was validated. Just don't try to put password if it says invalid password. Reset phone and then enter your password. .. Temporary workaround. Expect Sony to provide bug fix soon

i bought this phone 2 weeks back. yesterday i swithed off my phone. after i switched on it i got struct with "Protected" interface.MXTP gave me the lockdown screen with the verify, wifi settings and emergency call options on it. So as I wanted to unlock my device i pressed the verify button and a log in screen for my google account appears. I use my google account on all kinds of different devices so I logged in. But here someting goes wrong.
When I typed in the username and password to verify it is my M4 it gave me a loading icon for 2 seconds and then it says "incorrect username and/or password" and my M4 stays locked. To double check if my password and username are correct i logged in to another adroid device and my laptop with no problems. So now I'm stuck with a brand new non working xperia M4.I have already tried to factory reset with sony pc companion.. but even after that the problem stands. in sony's website on a post the said that " as this MXTP is combined with boot loader even after factory reset the problem will remain". as im from srilanka i dont even have a service center. helpless at all.. if anyone know the way to get rid off this please help me..:crying::crying:

What a Fu***** Sh**
I have a Sony Xperia M4 Aqua dual sim and updated my android system yesterday up to lollipop. After this update the "my xperia theft protection" was automatically activated. I tried to log in with my gmail account and my password numerous times. I even tried to reboot the phone a couple of times. The password and gmail account were absolutely correct and I was able to log into my account on a PC without any problems. The "my xperia" app accessible via myxperia.sonymobile.com located my phone in the middle of nowhere and even deleting my data and reseting my phone did not work. The only fu***** thing that did work in the end was to repair and reset the phone via Sony PC Companion. How the fu** can you create such a fu****-up software? My Sony Xperia M4 Aqua was a piece of sh** and fu***** useless for a whole day until I figured out how to fix it and now all my personal data including pictures, videos and everything else is lost...... Thanks Sony! Big THANKS!
P.S: Sorry for all the stars! ****
Are you connected to internet? You must be connected via wifi before introducing the google password
El vive en la piña debajo del mar
Yes, of course I was connected to the internet. I even tried a couple of different WiFis just in case. All Wifi connections were fine, simply the MXTP function is totally ****ed. Well, customer service told me that I should send it in to Sony customer support (10 days). All my data would have been lost anyways. Data recovery would have to be payed by me. Well I suppose this is real customer service! :good:

It's a matter of authenticating My Xperia to Your Google Account. When you are in Google sign in page try to get help from the page by choosing "I know my user and password but I cannot sign in" after Google authenticate the program, you will be able to authenticate.
Hope this helps.

Hey guys.
Here is the story ... I received my Redmi 3 Pro device back from the Xiaomi because it was sent there due to faulty camera. When I turned on the device it said This device is locked and there is a little button Activate this device. After that the screen shows that the device may be associated with existing Mi Account, which is my account. When I enter the password and tap on Activate I get an error saying Couldn't verify Mi Account ID. Can't connect to network.
How the hell can I connect to network if I even can't get past this screen.
Does anybody have an idea? I bought the device months ago and couldn't use it even for a day because it took them almost three months to replace the camera.
Any help is appreciated.
Thanks.

Try to use a sim card with mobile data and no pin. It should automatically connect to the internet and allow you to activate your phone.

Thanks ... worked like a charm
In my case it happened after disabling some stock Mi apps on an officially unlocked phone. Trying to connect would fail because the required dependencies were not available. The easy solution was to reboot into the twrp recovery and delete the file /data/system/users/0/package-restrictions.xml — the file gets recreated after boot with the default stock package restrictions.
Hello guys, this is my first post so please forgive me if I'm gonna ask a dumb question.
My situation is I switched from OTA beta ROM to the MIUI 10 stable ROM after it resets my phone the first screen that pops up was "This device is locked" / "This device is associated with an existing MI Account. For security reasons, you need to enter the password to verify the device".
Heres what I did.
1. I open the wifi settings to sign in to my wifi connection
2. I click to the "Activate this device" button. Then it put me where I should put the password. Note: there's no tab or box for the username or MI Account ID.
3. I entered the password of my MI Account. Note: I save it on my computers sticky note so I'm sure I entered the right one.
After those 3 steps, the system says "Couldn't verify MI account ID. Invalid username or password.". So at first I was puzzled so tried to do it 3 times and I turned off the hide password function to make sure that im entering the right password. But after many times of trying, I still can't log in. Then I tried going to "Forget Password".
Heres what happened.
1. It asks me the email address that I used for my MI Account.
2. After I submitted it, it says that they will send an Account Verification Code to my email. Note: I did change the password for my MI Account before this incident so I'm sure that I'm using the same email address on my MI Account.
3. Then I went to my email account but I didn't receive any email after checking everything i.e "Spam and etc.".
4. I thought I did a mistake so I tried it again(Sending the verification code to my Email) but I still received nothing to the point that I've used all my attempts and I can't do it again for 24hrs.
So I tried to log in my MI Account on my desktop because I always save the passwords on the browser to check if I can log in or I cant. So when after trying it says the same thing that the password is incorrect. So I went on my browsers setting and went to "Password" and there I found the saved "Password for my MI Account". So when I turned off the hide password function it shows me that the password I entered on my phone is the same password saved on my computer's browser for my MI Account. So I tried to click the password on my computer's browser hoping that it will direct me to my mi account webpage, But after clicking it, it sends me to an empty page with this "{"result":"error","reason":"expires_in参数不能为空","code":10016,"description":"缺失必选参数"}" .
I really don't know what to do. I tried doing the hard reset option. I wiped my data and then Reboot my device. But even after doing all that it always sends to the "This device is locked".
Im really out of ideas this is my only phone so I was really a bit frustrated and stressed out for not being able to use it. So id like to ask for your guy's help. I hope you can help me with my problem. Even if not I still want to thank you all for spending time to read my post.
I'm having the same problem, did you get a solution?
And I'm having the same problem with my brand new Redmi Note 8 Pro. I think I've changed my password almost 10 times but still, the problem persists.
After setting a super easy passwrod like "J12345678" my problem solved! xiomi really sucks!
Hello there.Here is a weird problem.One of my students brought me his mobile phone (Doogee y7).He said he put the pattern wrongly for some times and now even if we put it right,the phone doesn't recognize it.I suggested factory reset BUT even if we did,when the phone starts again it asks for the pattern.He doesn't remember the email password even if we know the email address.(I ll try again to login to gmail) but until then,is there a way to flash cwm or stock rom again so I can unlock it?I have to say that unfortunately USB debugging is not enabled..any help will be much appreciated even if I don't think he ll have any luck with it.(one of the biggest retail stores in Greece told him that the phone is dead and nothing can be done.)
