hi first of all i'm not a dev and i don't know much about deep functions, so i write this question as a regular user and to find answers that can be advanced in nature but should be easy to understand.
there are flashable zips available to break the lock screen security and to gain access to android device and access all apps with accounts logged in and everything else!
first of all i want to secure my device from any weak points like this, i don't want anyone to bypass my lock screen, but as i talked to a person about it, it looks like i can't survive this "Lock Screen Security Bypass" hack which removes some keys to break the lockscreen security.
then there was a suggestion to not root / unlock bootloader, not to flash custom recovery and not to turn on usb debugging. well even if i do that, there is still a possibility to unlock bootloader from odin mode and or may be flash something from there to break lock screen security, and gain root access and then flash this security bypass zip.
so what i can think is the only way to survive is to encrypt whole device? am i right?
and if i have to encrypt my whole device including ext-sdcard then will all the tweaks work? like xposed framework and it's apps etc? will my phone eat more battery? if i encrypt my device will i survive this lock screen bypass hack ?
please give your opinions by looking at all the possibilites. thanks in advance.
or may be if there is a way to put a password on custom recovery as well as all other modes from where someone can flash things into my phone?
i never heard of anything like that, but why no one is thinking about it?
no one?

Hi guys, i hope you can help me out here.
a Friend of mine is a taxi driver and had a guest who forgot his money and paid with his Moto G 2015 8GB.
As a friend of good deals, my friend now wants his father to use this Smartphone since it offers enough for his needs.
I already set it up from the scratch, but google now wants me to login with the first account data from the previous owner, which im afraid-, we wont be able to obtain any more.
Id install Cyanogenmod without Gapps to ignore the Google Questioning, but i need to check the "Oem bootloader unlock" option, which i cant, cause i cant setup the smartphone any more.
I hope anyone of you can help me? The Phone it not stolen, so as far as it is possible, please help me!

Goto stock recovery and using vol.down+power key u will be in fast boot mode using vol down chose recovery mode and press power key to enter into stock recovery. If u see a dead android just press power key first and holding it press vol. Up then just scroll down to factory data reset and now every g account will remove. Now set it up
A factory reset will probably not help. Moto G implements the new Factory Reset Protection feature which Google did introduce with Android 5.1. This check for the password of the last Google account registered on the device will survive a factory reset.
To my knowledge there is a way to circumvent the Factory Reset Protection on some Samsung devices due to a faulty implementation by Samsung (this was in the news a few days ago).
But this will probably not help with the Moto G.
Just reflash the stock firmware and you will be good I hope
You can't do anything with stock firmware, you can't unlock bootloader. The new system protection is exactly for that purpose. If your reflash the firmware via fastboot, at first boot prompts you to login with any google account used before in the phone.
The only way to revert the locked status is login with google asociated account and wipe from the settings menu once the phone has been unlocked.
i tried the stock firmware reflash as well.
you so are telling me there is no way to get a working firmware on this phone without going actualy in the developer options and activate bootloader thingie?
i mean google did a good job on that part. Still sucks though, but thanks for the answer

Yes, you have no option. To unlock bootloader you need to turn on the oem unlock permission in settings and actually you can't enter in that setting.

When you reflash the stock firmware via fastboot it clear all data & cache. When boots with clean system it prompts again to activate the phone.
For one side is nice to see that this works... Too bad for you... I guess you already googled it right?

Hello
Aim of this topic is to share ideas to make custom OS phones secure in the ideal case reverting chain of trust from hardware to OS to be secure. What I heard up to now:
fastboot lock command - but isn't it Nessus specific?
recovery image with password prompt
Do you have other ideas?
Is it possible to password protect custom recoveries for tab 4? I mean its too easy to remove key file and boot up without password protection....
Nope.. That's the downside to having a Custom recovery..
Even with the Stock Recovery there is no real security.. But if you want to protect your system best, simply find the Stock Recovery.. flash it..
You should be fine if your worried about people deleting important files.. Shame the Galaxy Tab doesn't have an FRP lock that in Developers settings you can lock your own bootloader so you can protect yourself from having your device stolen and wiped..
Brief about phone
I need to open this phone without losing data. This is PIN locked phone[Deceased Person's Phone]
Developer Mode Disabled
Any way to unlock it.
Via
ADB
I need how to root it and remove its pin number any how.
While rooting there should not contain any risk that involves data wipe.
New update
I cant flash twrp via odin
Custom Binary block by FRP lock
Question: If i flash orginal stock rom would it delete all the files and setting stored in phone
There should not be any data loss coz it needs to open phone of deceased person.
Did you unlock the phone?
I am in a similar position with my samsung J700F.
Did you find any success mate?
