Is there any way to secure android like ios7. In case if i loose my phone then no one can use it. Is it true a hard reset will remove my pattern or password? My phone is non rooted. Can someone install custom recovery too?

There is not fool poof way to prevent this. Even on IOS7 the security can be gotten around. Best advice is to make sure you are backing up your files.
Google does have a remote wipe option built into the Android OS. That is your best bet.
There is no full proof way to make render unusable, but you can call up your carrier and ask them to blacklist the IMEI so they can't use sim cards with it anymore.
You could however, protect your data. Do this by: encrypt your device, stock recovery, disable USB debugging, lock the bootloader. At least with this, if the device is stolen, if they don't know how to flash factory image, they'll need to enter the encrypted password to boot into the phone and can't copy over your datas.
You should also look up the app Cerberus, which with root can survive through factory reset (as long as they don't overwrite or format the "system" partition).
Hi there,
Friend of mine using Lenovo A6000+, Doesn't have google account in that phone. It was secured with the pattern lock. But unfortunately he forgot the unlock pattern. Since he have a lot of contacts in that phone, there is no way to reset it. Its full stock version. Just a basic user., so no root access or anything. In this scenario any other way to unlock the phone without doing a factory reset? The google answers are helpful only if the usb debugging is enabled. Since it is not rooted and basically a very common user used that phone, i don't think usb debugging is enabled. Any help appreciated.
By the way, i'm also thinking of flashing a custom recovery into the phone. Will that be of any help? Would it cause the phone to lose data? Will that need usb debugging enabled to do it?

I dont think, there's anything you can do about it. Ask him first, if he had ever connected to pc and authorized it for usb debugging. Otherwise, the only option left is to factory reset.
Edit: Brother, I'm working on something to change the pattern, which obviously I'll tell you. I'll make a flashable zip which you can flash through twrp. Lets see how this goes.
I'm not sure, if I'll be able to do it. But if it does, it would be very helpful for everyone.
:silly:
Edit 2: Finally I got it working!!! hurray!!
Just flash this zip below and the next time your phone boots, you can enter any "more than 3-dot" pattern and the phone will accept. Later, you can set new pattern or anything.
:angel: :silly:
P.S. I used CWM recovery on stock KK to flash it. Don't know why but I couldn't manage to flash twrp. Who cares anyway, if our job gets done. :silly:
Hello fellow people of XDA!
Today I got an OTA update for my S7 edge (SM-G935F). The update has installed fairly fast (after the first reboot). But then, it got stuck on a decrypting loop. I have enabled prior the full phone encryption, and set it to ask for a password at each start. I entered the password correctly, as it said Starting Android... after, and since then, only the rotating padlock is showing. Every like 5 minutes the soft buttons are lighting up for a second, but then nothing is happening. After a while it even gets hot, but still nothing. I had this issue at the previous update too, but it started after like 30-40 minutes. Now 90 minutes have passed and still nothing.
I can reboot to the recovery and bootloader screens, and everything is fine. Knox not tripped, not rooted, everything official. In the recovery screen it says that my CSC is ECT (but according to sammobile it should be CNX).
Some additional info: samsung/hero2ltexx/hero2lte
7.0/NRD90M/G935FXXU2DRAG
I will try to flash a stock rom (PDA: G935FXXS2DRAA, CSC: G935FROM1DQJ3). If that doesn't work, I'll flash today's rom (PDA: same, CSC: G935FVFG1DQI1).
Any tips/help would be greately appreciated! Would not want to fall to the wipe data method, because I don't want to lose everything... But then again, I guess that would remove the boot password...
Thanks!
Update: After waiting for like 10+ hours, nothing has changed. Maybe I shouldn't have forced a reboot after an hour of the ota update? Going to try flashing the firmware now.
Update 2: I flashed the firmware, now the buttons seem to light up less often. But after an hour of decrypting, I guess the ultimate soultion would be to do a factory reset, since no one is helping...

I set a password when I enabled Secure Startup.

Then use that same password, i think there is confusion, there is a password when you enable fingerprint and then a password when you enable secure startup. Be sure not to confuse them. If it still happens, then I guess there's got something wrong with the update, and only way is a factory reset. Btw, i also updated and i normally entered secure boot password and it started okay. Don't know what caused this for you.

I entered the password correctly, as it stated "Starting Android..." then the rotating padlock took forever. More than 10 hours even. But in the end, a factory reset helped me. But rip my photos and memories...
Don't use device encryption anymore and leave OEM unlocking enabled in developer options.
Those two settings cause more hassle if you want to keep data, and make backups from time to time using Samsung Smart switch on computer. Use a microSD card to store and take all your photos from camera.

Right, but i use encryption and i could update without any problem, don't know what caused this issue with him. But one should backup all data BEFORE updating, as i did to save yourself from such hassle.

Yeah, it's a sure thing I won't turn on Secure Stratup anymore. I don't know what OEM unlock does or does not, but right now, I don't have dev options enabled. If I had a microSD then I couldn't care less about resetting my phone, but since I don't have, because I have two SIM cards and a memory card has no place left, I feel bad.
Still, I don't know caused this issue. I had OTA updates before with full device encryption enabled and I had no issues before. I kinda used the same disk space at every OTA, so it should have took the same time... And I have to mention, that I did not tamper with the software. No root, no custom rom, and software only from the play store.
To enable developer options you click Build number 7 times which is located in the Software information tab in settings.
OEM unlock allows you to flash and boot the phone with custom binaries (Custom Recovery, Kernels, Roms). You can leave OEM unlock disabled if you don't want people that may steal your phone and use it for themselves.
With OEM unlock disabled and a google account signed in, it will block anyone from using the phone after a factory reset on stock Samsung firmware as it will prompt the user to enter the google account that was associated with that device.
Unfortunately there are rare cases that a OTA update may fail. Reflashing correct stock firmware usually fixes it but in worse case scenarios a factory reset will be required.

Never had OEM unlock enabled, because I didn't know what is does, so thanks for the info. I reflashed the correct stock firmware, but that didn't help either, so I had to resort to wiping the data... Regarding this, do you know by any chance a good software for recovering data without root?
I don't know of any unfortunately, if anyone has any good paid ones that actually work please post here.
I have a Pixel 4 with Android 10 on it. It also has Android for Work (Enterprise), i.e., it is managed by work admin who can remote reset the device and also control what gets installed or not. It has MobileIron MDM agent installed on it.
How can I wipe all of this Android for Work and remove the MobileIron completely? I have no personal data on it and can do factory reset and the phone is carrier unlocked as well. The OEM unlock in Developer Options is greyed out.
Most likely, the phone was bought from Android Enterprise, which may also mean the app is built into the firmware - loaded as specified by whatever organization ordered the device from Google. But there's a couple things we can check:
Go to Accounts under Settings, make sure there is no work profile there.
Go to Security > Device Admin apps, see if you can remove the app there.
Failing those, try a factory reset. If the MobileIron app survives factory reset, it's built into the firmware.
Unfortunately there isn't much that can be done to get rid of it with a locked bootloader. You could try sideloading an OTA update but that may fail because the firmware won't match. You can also try the Pixel Repair Tool although I suspect that may not work for the same reason.
Let us know how it goes!
The phone is definitely Android Enterprise as I wrote above. There is work profile and MobileIron installed. Factory reset doesn't help. It always tries to want to setup as Android for Work.
I can't sideload anything I guess as it doesn't go to bootloader mode at all. I will try Pixel Repair Tool. Thanks for your suggestions.

What do you mean it doesn't go to bootloader mode?
Are you able to enable Developer Options and USB Debugging?
My bad. I tried Pixel Repair tool. It went thru successfully but did not remove the Android for Work so I guess I am stuck with a paper weight. Nothing can be done effectively. That's fine. I will wait for black friday deals and buy a new phone. Thanks.

If the device is enrolled in Android Zero Touch, there is nothing you can do unless the IMEI is removed from Zero-Touch.
Hello there, I'm using OnePlus 6t on OOS 10, somehow my kid changed the lockscreen pin and now forgot.
I've read multiple threads and asked a lot of people, but there seems no method to bypass the lockscreen pin.
I'd some important files which I couldn't backup/ not until my last backup.
Is there any way possible to recover my files after a hard reset as that's the only alternate i can think of without bypassing lockscreen without root.
FYI: Bootloader locked, currently locked, haven't hard reset yet, usb debugging off.
Nope, if you hard reset you lose everything. User storage is encrypted with a per-session key that is wiped when a reset occurs meaning everything on the phone becomes useless garbage the moment that key is lost. If you have adb enabled and have authorized your computer once before you might be able to pull files off using that but otherwise you might be screwed
The lock screen is designed to keep people out, wouldn't be much use if it let people exfiltrate data whenever they wanted
Don't even think you'll be able to get the pin off the phone. When you reset Google asks for the old pin used in the device.
If USB debugging is off, I don't even think you can flash stock firmware onto the device either.
You're pretty much screwed.
The best way to do is MSM tool. If you don't know the password your can't even get in to recovery mode( required password). By doing that all data will be gone.
