OK, so most of us already know about "Google device manager" feature or Samsung's "Find my Phone", you can lock your phone, erase all the data, locate it if it's online.
But in all this cases your phone can be still hard reseted (vol button + home button + power button, any of this combinations) and be used again.
What am i asking is, if you got your phone lost or stolen, can you lock completely your android phone, so any bad guy who find it and doesn't want to return it, can not use your phone at all (hard reset feature disabled), so the only think the thief has left is to throw the phone away or to sell it for pennies for it's battery, screen and so on.
P.S. This feature is already included in all iphones
This feature is not on iphones, a simple bootstrap and DFU mode can still initiate a wipe
Also if a thief still wants, they just have to JTAG the device and wipe it that way.
Reactivation lock is a better alternative

Hi community, I just purchase in ebay an Atrix 2, was a bargain. Well, the problem is that I was going to unlock it, because Im in Ecuador, so purchase a unlock code, but it didnt work, I wrote asking other sellers if they can provide another code, but all says that thats the only valid code to unlock it, so I think this thing is in a hard locked state (more than 10 times wrong unlock code) I just try 2 times with the actual code that I have.
I search in the web and a solution for an atrix 1 was to flash a radio. Im new with this device, anyone have any suggest or fix for this problem?
Hope you can help me.
If anyone have access to unlock codes maybe can check if I have the right one, this is the info that the unlocker give me:
for IMEI: 356378042076331
unlock code:62659983
Sold the phone as parts, anyway if there's a solution please post it to help other people.

Samsung Galaxy Tab 2 10.1 Hacked, Touchscreen unresponsive
Hi! I need help with my tablet.
Device: Samsung Galaxy Tab 2 10.1 Tablet, model GT-P5113 TS. This model doesn't have a way to yank out the battery.
What's wrong: Touchscreen is not responding.
Current state: Attempting to drain the battery. Doesn't appear to be turned on. Factory reset apparently performed.
What happened: Sorry, this is long. It is as best as I can remember it. It may be somewhat inaccurate.
Yesterday evening, I was on my Windows laptop and logged into my Google account. I *thought* I used the Google Play Store to install Chrome to the tablet. (I had looked at the html5test website and it said Chrome had a higher HTML5 rating than the Dolphin/Jetpack browser I've been using on my tablet.)
But something went terribly wrong.
After sending Chrome to it, I unlocked the tablet and used both Chrome and Dolphin to go to html5test website. They both scored the same or nearly the same. I don't know if any of that is relevant, but I'm including it just in case.
At some point after that, I woke the tablet with the power key and used my unlock pattern on the dots lock screen.
That's when I saw what I believe was mal-ware in action. The settings menus were scrolling and sub-menus being selected, all by themselves. I couldn't say exactly what was changed because whatever program or script that was running the process was going extremely fast.
When I realized it might be trying to send out data over my Wifi network, I turned off the Wifi router in my home.
I repeatedly held down the power key to turn the system off, but doing so only rebooted back to the useless lock screen which was not responding to anything. The normal method of holding the power button for a few seconds to bring up the menu and then tapping the "Power Off" option on that menu refused to power off the system. Nothing on that menu responded to touch.
Entering my pattern on the lock screen did absolutely nothing. I didn't even see any lines traced when I ran my finger over the screen.
At some point, I pulled out the external SD card. I have no idea if whatever hacked the tablet also put a copy of itself on the SD card.
I called a friend who looked up how to restore the tablet to factory settings. I didn't understand the directions exactly, so I ended up on a screen with a Warning!! about installing a Custom OS. (Holding down the Power + Volume Up seems to get me there)
I left it on this screen, and I turned my router back on and using my laptop, contacted Live Chat at Samsung but they didn't understand my problem. They told me to reboot the device and swipe my pattern several times and then after several failed attempts I would have the chance to use my Google credentials to get into it. But the device apparently never registered that my swipe attempts were failing.
So my device was booted up with me locked out, with the WiFi router on for a little while again. I turned off the router as soon as I realized that. That disconnected the chat session, but since Samsung chat wasn't helping me anyway, I didn't bother trying to go back.
I got the device back to the "Warning!!" screen. Then turned the router back on and searched for how to do a factory reset of the device. I found a video on YouTube and followed it.
I pressed the Volume Down and Power buttons simultaneously, followed by letting go of the power button. That brought up a menu which contained several options, including an option to do a factory reset. I used the volume buttons to highlight that and pressed Power key. A second screen came up and I used the volume buttons and power button to select "Yes" to confirm the reset.
It appeared to have done a factory reset, rebooting eventually.
However, after that, when I tried to tap on the touch screen to move forward through the selections, the touch screen was still unresponsive!
So I brought back the "Warning!!" screen and ran the battery down until the screen was blank and it wouldn't start when I held the power key.
Then I charged it for about 20 minutes and rebooted it. I think when it came back it was on the Recovery menu. I think I did a second factory reset, but not 100% sure. It eventually rebooted after a lot longer than usual.
When it came up, it was saying battery was low. I tried to tap the OK button, but nothing happened. Behind the battery window was the first setting screen to set up the device for the first time after a factory reset. (I think selecting USA?)
I brought back the "Warning!!" screen and left it on overnight so that the battery would run down.
That was about 8 hours ago. When I woke up, I used clear tape to keep the power button pressed down, to ensure that the battery will continue to run down.
____________________________________________
What do I do next? How do I get the touch screen to start working again? It is not a hardware problem, unless mal-ware can break the hardware. The touchscreen had been working fine until this happened.
Should I take the tablet back to Best Buy where I bought it at least a year (maybe 2 years) ago? I don't know if it's still under warranty.
I have over 20 year of experience as a software developer, but not for Android. I am not very experienced with doing anything to hardware.
Should I try to fix it myself?
I have never rooted any Android device and I'm not sure what that means, either.
I've never re-installed the ______ ? (rom? image? Odin?)
I read on this and/or other forums that there's a way to replace something, but the instructions were beyond my level of understanding. I would need the procedures to be broken down into steps which don't assume too much about what I know.
I understand how to download a file to Windows, given a URL for it. I understand what a zip file is and how to extract it. I understand how to press hardware buttons and plug in cables, and do these steps in the order I'm told.
I don't understand what I'd use to get the downloaded whatever-they-are onto the tablet to replace whatever-the-other-thing-is so that the touchscreen works again.
As far as I know, Odin is a Norse god.
The only firmware updates I've ever done are the ones that the device does on it's own through Samsung's updates.
I'd deeply appreciate getting this device back since I have extremely limited funds and probably won't be able to buy a replacement.
Thank you,
Linda

Definitely sounds like malware. You have two choices that I see, either root and custom rom or flash back to stock. Since you are stock you'd just be overwriting your existing install. Read this thread and decide your course of action http://forum.xda-developers.com/showthread.php?t=2203309
So I'm brainstorming the scenario that I get my device stolen. So here's my plan so far:
1) The device has software with which I can locate it and send various commands to it.
2) Lockscreen is password protected.
3) Power menu is disabled when in Lockscreen.
4) Notification drawer also disabled while in Lockscreen.
5) The device happens to not have a removable battery.
So in my head that leaves the robber with two options to shut down the device:
1) Figure/Google the soft reset combination and reboot into recovery.
2) Plug it in a computer with ADB and fastboot installed and do whatever he/she wants with it.
From what I understand, it is pretty much impossible to disable the soft reset combination. Am I right? If I could disable that, I could surely buy some time and make sure I can locate the phone, given that the battery doesn't die.
So can it be actually disabled? Perhaps from a hacked bootloader of some sort?
Also, bonus question, could I install some kind of a RAT on the phone to automatically install when plugged into the USB port? I could get a nice sweet revenge on the b*****d that took it. Thanks!
edit: Oh crap, the title was meant to be "Worst"
Samsung phones do something like that
and when your sim is removed as soon as its taken?
So a customer brought a Note 7 from Verizon to me with demanding Google Account in order to continue setup. After the usual searches and clicks from forums to forums I was unable to solve the problem. I even booted the phone into download mode and tried to reset using Z3X Box (I choose SM-N920A) but still nothing. So, in disappointment, as I held down both Power and Volume Down buttons in order to reboot phone, something happened. I came across a menu I am kind of vaguely familiar with - the Maintenance Boot Menu.
Not only interesting is the fact that it has useful options like Safe Mode and Factory Reset, but the most interesting factor was the last option, option number 5
USB Debug Mode: Turn on USB debugging option under Developer Options.
I used the Volume buttons to navigate up and down and the Home Button to choose option 5 and the phone rebooted. I re-plugged the phone back to computer, waited for ADB drivers to install, fired up Samsung ToolPRO once more and choose SM-N920V (again!). I navigated to the Unlock tab and clicked Reset FRP. I said okay to the questions asked and waited for it to load. I still clicked OK despite the warning about wrong model number and just like that factory reset was done (By Samsung ToolPRO of course). I checked by phone and nothing happened!! What the- I took a deep breath and clicked Reset FRP, again. And just like that, the setup screen vanished. I went into menu and did a factory reset of the phone and now all is good. Cool huh?
NB: I know not everybody has Z3X Box for servicing phones but the essential is that ADB can be activated and that counts for something right?
Yep. Where's a good place to get it?
It was hot. I don't think the phone was necessarily feeling the heat like me... but... the way it was acting... maybe so?
The second to last day of my vacation at Walt Disney World (first time!), my S8+ started acting wonky. I tried to take pictures and the application wouldn't work right.
So, I rebooted.
Now, I'm staring at a screen with a textbox at the bottom of the screen and some text near it (I don't recall it verbatim) "Enter your emergency password".
What? What's an emergency password? Typing in the textbox, it was obvious that it wasn't a numeric-only textbox (for PINs) but it was alpha-numeric. I simply don't recall registering anything but a pin and my fingerprints.
Freaking out, I kept trying to restart and worked with the power and volume buttons.
All I continued to see was the Samsung logo.
Suddenly, I got a black screen with text telling me things were being erased. I then see a blue screen with an android bot telling me stuff was being erased.
After a bit, I was back at the language selection.
Gone. Pictures. Data. SSD... entire phone... fully erased. (Thankfully, a majority of my pictures were immediately put into Instagram... the lost pictures I used the phone's camera app because it works better than the Instagram camera).
Don't have my laptop... so I don't have my password database, so I cannot get into ANY applications.
I know there are requirements for Microsoft Exchange, and other applications that require special security for being a device administrator... I'm not aware of Exchange requiring a password for the phone but... who knows? I didn't enter the password wrong too many times.... even as hot as it was I still used my print to unlock the phone.
Man, that is horrible. My condolences. If you can boot the phone into recovery mode (Hold down volume up, then the Bixby button & then the power button...all at once). Once in recovery, do a factory reset and you shouldn't have to enter that 'Emergency Password'. Unfortunately, everything is lost unless you ran a backup into the cloud or on your 'puter.
Sorry for the post if you've already reset the phone as it sounds like you might have since you mentioned the language screen.

Yeah I didn't have the choice -- the phone decided to reset to a fresh install point. Once I got back home I restored to a previous backup after trying everything I could to undelete stuff on my SDCARD.... but none of the software I tried would work... kudos Samsung... your deletion of my SDCARD was VERY complete...
Did you have the SDCard stand alone or merged with the internal storage? I'm surprised that got wiped also.

The only reason I see for this to happen is if on the "lock Screen and Security", inside the "Secure Lock Settings" have enabled the "Auto factory reset".
Biometrics won't trigger a device wipe, they will only force the pin/password field on too many attempts.
You say Exchange. Is this a corporate account? Is there a possibility that someone remotely wiped your device? Log into OWA (the web interface of your Exchange), navigate to Options -> See All Options, then click the Phone tab and see if a wipe was sent to it. Because what you described sounds a lot like a remote wipe. (Though I've never seen the emergency password field.)
Also make sure that you're not violating your corporate policies. Granting admin access to the Exchange app gives your company full control over your device. They can see you accessing your email with it, and if you're doing something that you shouldn't be, they will wipe your device.

No way of knowing but I don't recall ever setting that (I wouldn't).
something corrupted your ROM it sounds like, somehow!
if it was the red box that says like "enter password" I believe it is actually "default_password"
