Is it possible to lock twrp with password? - Galaxy Tab 4 General

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..

[Q] Bootloader & recovery security

Is there a way how to set a password or PIN lock for the bootloader or at least the recovery? There's been a lot of break ins in my area lately and when someone steals my phone, I wanna make sure that it will be rendered completely useless (Including IMEI blacklist) and non-recoverable.Is there a way how can be bootloader & recovery locked so a thief can't access the recovery without a password or a PIN lock and thus not able to reset the phone to factory settings?
So far, any anti-theft software I've seen doesn't have this ability and can be easily removed by factory data reset

I believe, but not sure, that TWRP has a PIN code system
You should try Cerberus or avast!, with root they can lock into the system which means the thief has to reflash an FTF file
EDIT
Nope, TWRP doesn't have PIN protection. If you want to secure your phone, some tips:
1. Make sure the on/off menu cannot be opened when the phone is locked.
2. Make sure your data is always on
3. Use CyanogenMod Account / Cerberus / avast! AntiTheft
x. If you phone gets stolen, use one of the above programs to lock and wipe your device.

how to completely secure android device ?

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?

Security and custom ROM

hi
two security features are keeping me away from a custom rom, i'd like your opinion about that.
First is the password that prevent booting with a password.
Second is, if someone install a new system it can't be used without providing the correct google accout and password.
I use those two protection on my phone.
I was wondering if they can be bypassed?
If he install a twrp boot then he erase the password boot protection?
Then he can install a custom ROM that will not be "locked" until he give the proper google account ?
Thanks.

Question about FRP lock and OEM lock

Hi,
I have a few questions about the FRP lock and the OEM lock on the Galaxy s6 running Nougat. I hope someone can help as I've not been able to find answers to questions this specific.
Ok, so, my first question is does the Galaxy s6 even have an OEM unlock option? If so, is it enabled by default?
Quick story before the other questions. I flashed TWRP and the sorts onto my s6 but decided to go back to stock and so flashed the stock firmware from sammobile through odin mode. After doing so I assumed the stock recovery would be restored and the phone would be as good as new right? As in all the FRP and OEM lock security features would be restored?
However, I did some research and found out that you can flash the stock firmware AGAIN as long as the firmware was signed by samsung even if OEM unlock is not checked.
My last question would be if someone was to use odin mode to flash the stock firmware, which is freely available, would the phone not ask for the previous Google account which was signed in on the device?
Hope is wasn't too hard to understand, I'm typing on my old S3 mini as I lost my s6 which is the reason I can't go and test this myself.
Thanks in advance
- There's no OEM lock on S6 (at least on international models). So, there is no OEM unlock option.
- If the bootable images (kernel and recovery) on your phone is Samsung signed, you can use FRP.
- If you want to revert the device to completely stock, I recommed that you should install a 4-part firmware.
- If FRP lock is not enabled on your device, phone won't ask anything about Google account (or Samsung account).

Hi,
Thanks for the informative reply. I have just one more question.
If I had enabled FRP through the Samsung Pass settings with my Samsung account and then I was to flash stock firmware on to the phone, would the Samsung FRP lock prevent the user from using the device by asking for the email and password or would the new firmware get rid of any of the security measures put in place?
I understand the FRP lock files are stored on a hidden partition not wipeable through the stock recovery however considering signed firmwares are freely available it would seem to me that the FRP lock would be deemed useless if anyone could just do that.
I guess my final question would be do signed firmwares downloaded online and flashed over the existing firmware wipe the FRP lock partition of the phone?
Thanks again for your reply

Phone will ask Samsung or Google account only if you wipe the data (we assume that FRP lock has been enabled before wiping the data).
If you don't wipe the data while flashing any firmware while installing (or the firmware you try to flash doesn't wipe the data), phone won't ask you anything.
And, if FRP lock enabled on the device, bootloader will deny to boot (or flash) the unsigned kernel or recovery.
There's no way to wipe FRP lock via Odin.
So, we can say that FRP lock is pretty secure.
Yeah
But u can easy **** with samsung when u flash stock 5.0 with odin and on pc have sidesync or someting like that samsung suck because with that tutorial u can bypass frp really easy

well here's hoping a typical phone thief doesn't know how to do that....
Quick question though, can an S6 be factory restored if the user only used the phone's PIN from the lock screen to the factory reset option in the settings app? Or would you be prompted to use your fingerprint? I read somewhere that factory restoring a device through the settings app disables the innate android FRP but i don't know if it's also the case with Samsung reactivation lock which is supposedly similar to FRP.
Thanks for the replies I appreciate it
Read on the way out from house !!!
Sorry for my bad but im now on the way but 1 yeah u will need maybe fingerprint for turn off reactivation ( frp) but first when u lost your phone use samsung accound on the browser for track lock etc 2 for factory reset u need only turn off phone and go to the recovery mode
