While I was attempting to unlock my bootloader I noticed the phone gave me a warning how it would factory reset my phone. Has anyone found a workaround to avoid losing all my data or has found an effective way to get a full backup with all app data being saved?
You may use official backup tool? Besides Google Drive can save some App data.

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).
Can I recover data from my own encrypted s5 Verizon phone (not rooted) w/password?
My s5 Verizon phone could not boot well recently so today I intended to clear system cache. I hold power + volume up+home buttons, maybe somehow it entered into download mode, so it warned me that install a custom os is risky and asked me to volume up to continue, or down to cancel(restart). I volumed down and now it rebooted, but all of sudden, my data is gone! It did not ask me for screen pin/password either as previously my phone was encrypted. (Or did I held power+volumn down to factory reset the phone? But I did not get a warning for that.
This factory reset was a surprise to me as I was not warned or told that they will wipe out the data.
Anyhow, my data is gone. Now I wanted to get it back.
Can I recover data from my own encrypted s5 Verizon phone (not rooted) w/password?
I know It's not difficult if it was not encrypted, as many third party tools can recover most of the data if the phone was not used much after reset.
I am wondering if anyone has any experience recovering data for an *encrypted* phone (with right encryption password though). Which tool can do that by prompting you the password for the encrypted data?
Here is the link regarding recovering data from factory reset: http://forum.xda-developers.com/showthread.php?t=2143188 However, I did not find a solution: what if the phone was encrypted and you do have the correct encryption password (if not I know it's almost impossible)?
Thank you in advance for your help!

Any thoughts, suggestions?
My phone was encrypted but not rooted. I have the encryption password. Any chance to get the data back from the phone?
I powered down my phone now and will see how to proceed after I get experts opinion on this...
My question basically is, can I recover data from an encrypted phone after factory reset if I have the encryption password? Anyone can help?
Thank you guys in advance.
Anyone？
I understand this is difficult, but I wanted to try before I give up.
I need experts here to shed some lights: is it still possible to recover the data from my encrypted phone after accidental factory reset, as I still have the screen PIN?
I know how to recover the data if the phone was not encrypted/not factory reset. I also somehow know how to decrypt the data inside the encrypted phone, but no way so far do I know if we can recover the deleted data from the encrypted phone if the files were deleted or the phone was factory reset, provided I still have the screen lock pin.
What I have done so far:
I rooted my sm-n900v
I also created a raw image in my pc using dd command
Next questions are,
where can I find the crypt footer (which partition), and how can I decrypt the deleted data after the factory reset?
Can I recover the deleted data from the encrypted phone first, but it looks like no tools can do that. All data recover tools like Recuva can only recover unencrrypted data.
Or should I first find the cryptor footer, figure out encryption key, but where should I find the deleted files first to decrypt from the encrypted phone?
I just came to realize what I was got into... This is the most difficult scenario to decrpt the deleted files from an encrypted phone. I do want to recover some very important files from the phone's internal/encrypted storage, regardless how stupid I look not backing up those very important data.
But if experts here say I am doing almost impossible thing... I will stop.
Thank you all for your attention.

BTW, my s5 ran Android 4.4 before, later upgraded to Android 5.0, a while ago before I recently accidentally factory reset. I just rooted it days ago after accidental factory reset.
...... If the above info will make a difference in solving my issues below.
Thank you.

From what I have read, the device encryption key is tied to the device Serial Number or Burned-In-ROM-Key. Meaning when you encrypt your device data, it encrypts the password in much the same way the device encrypts its "Verity Hash".
So from what I've gathered it is possible to do a factory data reset, encrypt your empty device using the same password as before, decrypt the empty device, and during that encryption/decryption phase:
Pull out the common denominator between the encrypted data you want to recover and the encrypted empty device, thus enabling you to derive the decryption key used for the data you'd like to recover.
Hi,
I was changing pattern. Somehow I applied wrong pattern and then locked phone.
Now I can't unlock with fingerprint. There aren't any connect Google Account button even I am connected to internet mobile + wifi.
I didn't install TWRP and my phone is not rooted. Are there any way to unlock without losing any data? I can do anything possible (like root or install twrp) if I wont lose data.
wont a hard reset work
Without TWRP you can't do much...

That will delete data.
Unfortunately, hard reset is the only way out of this. Since the data on the phone is encrypted, you require the pattern to decrypt the data in order to access it. This also includes access to the hash that is generated by your fingerprints which is why you need to enter your PIN or pattern on startup before you can unlock with your fingerprint.
Bottom line, never ever forget your backup authentication method!
Edit: I can't guarantee this will work, but it's worth a try:
Visit https://www.google.com/android/find (Find My Device)
Log in with your Google account
Click "Lock" and enter a new password.
Try that new password on your phone.

Hi Guys,
my MOthers new Xiaomi MI A1 was stolen this week.
1. Now my Question, is it possible for the Thief to get on her Data?
Theroretically not, because the phone was on last official android update 7.1.1 (nov sec patch)
Phone was saved with a Fingerprint and PIN and ohone was encrypted.
2. Is it possible for the Thief to hard reset the phone via adb or fastboot to got a use for the phone (resell etc)
Thanks
Even if he would format it, the phone will ask to log into Google account of the user that was logged in before formatting. I doubt the thief is smart enough to bypass it.
1. did you enable "require pin/password for phone startup"? If yes, there is probably no way to decrypt the data without the PIN. If no, thief could unlock the bootloader (Xiaomi is the only phone I know which doesn't perform factory reset for this action) and use the default encryption password to mount the data partition in TWRP.
2. factory reset will trigger FRP, but it's probably quite easy to bypass it with a bit of patience.

Yes PIN was set on startup.
" If no, thief could unlock the bootloader (Xiaomi is the only phone I know which doesn't perform factory reset for this action) and use the default encryption password to mount the data partition in TWRP. "
How can he unlock the bootloader? I think he need DEV options and OEM unlock enabled, right?
Consider: There is no MIUI on the phone, its a Android One Phone.

You are right, I forgot about OEM unlock option (I enable it by default for all my devices). In this case, data should be safe.
My phone is unlocked but OEM Unlock was disabled in Developer Options... So I think is not a problem having that option disabled.

Try to erase using 'Google Find My Device' i think you can erase the phone using that, also you can know locations where the Device right now.
Just try, Good Luck :good:
Hit 'Thanks' if helped. ASAP
I am fairly certain there would be ways to circumvent the google account verification using fastboot commands and MiFlash. It takes some work and patience, but it should work.
However, as far as I know there are ways to get the IMEIs of the device blocked by carriers when reporting the device stolen. Not entirley sure what needs to be done to do this, but this would render the device useless for the thief.

Imei blocking is not really gonna help. It's too easy to change.
Yes there are ways around everything in this thread and tuts to do it are only a search away. Heck we host most of the tutorials right here.
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.
