[Q] How to enable Fingerprint Scanner with full device encryption??

Hi,
I bought the Samsung Galaxy S5 and the fingerprint reader works reasonably well (as in it works, nothing in comparison to apple though, so don't buy it for the fingerprint reader ) for unlocking the screen...
However its a work requirement that my phone has full device encryption, as phones are regularly stolen where I travel.... it seems when I enable encryption I lose the ability to use the fingerprint reader to unlock the phone .... I bought this hoping that I could avoid having to type in my complex password just to unlock the screen, as I got so tired of doing that with my S2
Is there any mods to enable finger print reader screen unlock + full device encryption at boot time for the Galaxy S5 yet? ... I saw some references to pattern unlock / pin with device encryption... but I would think the fingerprint reader is different...
Thanks!

S5 Full disk encryption with fingerprint unlock
I also have this question. I believe on the Nexus 5 it at leasts lets you use face unlock with full device encryption. And I read on one article that you should be able to do this but i do not think the author actually tried this. I will say from my own personal experience that you can infact decrypt the device after encrypting it without doing a complete wipe of the device and you can restore the use of fingerprints to unlock your phone. It seems like for security minded people this would be a great feature but if it is unable to be used with full device encryption it seems a little pointless to me. Being forced to use a PIN or password to use encryption is a big pain point for android users who want some type of security.

Yes I can't believe that no one has really complained about this yet - but I guess encryption isn't' that important to people as I imagined

I am having the same pain, as I use my S5 for BYOD.
It makes no sense when you can use fingerprint to make payments with paypal but not unlocking the phone when it is encrypted.
Hope Samsung can enable this feature in next update.

I'd like this too.. as well as, the iPhone has a cydia app (that a friend of mine showed me), that you can basically disable the power button from turning off the phone while it is fingerprint locked. That would definately be nice to have on the S5 (since it's done through an app). That would have stopped the person who stole my wife's S4 from turning it off when it was blasting the locator ring at them!

I can't believe that the fingerprint sensor can't be used if encryption is enabled whatsoever. I could understand the iPhone model, requiring a pin before a fingerprint can be used, but by disabling fingerprint lockscreen, boot unlock, and SD unlock, the fingerprint sensor is now wholly useless for convenience.
It's too trivial to extract data from an unencrypted Android. By not supporting encryption with a measure of covenieve, I don't see the point in including a fingerprint sensor whatsoever given the current software limitations.
Please, someone, figure out what sqlite/settings need to be changed so we can make decent use of our phones fingerprint sensor.

After some experiments, i found out a procedure to enable FDE and fingerprint lockscreen. Root is required (or at least I guess, I didn't try with a non-rooted system...).
These are the steps:
1) set up fingerprint lockscreen
2) with a root explorer, go to /data/system folder, and backup locksettings.db, locksettings.db-shm and locksettings.db-wal to sd card
3) set up password lockscreen
4) encrypt the device
5) when encryption is done, restore the backed-up files to /data/system: you should have fingerprint lockscreen again (no reboot needed, just turn the screen off, and magically the password should be vanished )
CAVEAT 1: with my system configuration, I wasn't able to encrypt the device directly: the encryption procedure started, but after reboot nothing happened, the device just booted normally. I don't know the exact reason, in some forums they suppose that it happens on kitkat when the device is rooted. I was able to bypass the problem only adding these steps to the procedure:
...
3b) with TWRP, backup the /system partition, and restore the stock non-rooted /system
4) encrypt the device
4b) restore the original rooted /system partition
...
I don't know if steps 3b) and 4b) are always necessary, let me know...
If you need these steps, don't worry if before restoring your custom /system partition the encryption password isn't recognized, just restore the partition and all will work fine
CAVEAT 2: once encrypted, I didn't find a way to unencrypt the device, because the unencrypt ion procedure starts, but after reboot the device is still encrypted, similar to what described in caveat 1. I tried to replace the /system partition with the stock one, but the encryption password was no longer recognized.
CAVEAT 3: the current TWRP (2.7.1) isn't able to mount S5 encrypted data partition, and restoring an image made with online nandroid backup doesn't seem to work either. So, if you want to make an image of your phone (and I suggest to do it ), do it before encryption

Hi guys! Did someone try this solution? I unfortunately have the same issue and unlock my device each time make me crazy!
Thanks in advance.

Same problem
I purchased a Galaxy S5 and I have the same problem, unfortunately I cannot root my phone due to security policies in my company. :crying:
I hope Samsung will solve the issue. :fingers-crossed:
Have anyone contacted to Samsung Support Center?

What is the consequence of boot loop if you are using stock boot loader? Odin mode required to recover? Something less drastic? What device model are you using?
I found a possible solution that involves deactivating SuperSU and running encryption from there. Still investigating. I am thinking that the solution from @fabiokino will work in this case too.

I'm curious about this aswell.

Doesn't anyone know a working solution?...
It is really frustrating the very least. I can't believe there isn't a way (or if there is, a guide) to do this (with or without root access).
I have also heard it is doable on the Note 4. See this post for example http://forum.xda-developers.com/showpost.php?p=57103664&postcount=7.

I just flashed the stock Lollipop ROM and guess what: It works!!
Samsung finally did it. No tweaking needed and it also works without root access.

How?

Well for me that really wouldn't be a problem. I don't have an SD card so I'm okay with just FDE. Thing is I really really don't want to root my phone... No particular reason other than every older android device I've done it on always ends up slow and buggy after a few months use until I reflash with stock ROM. I would like my phone to stay buttery smooth for once..

You could root then unroot it after you have encrypted it

you're right... plus it's not really the "rooting" process that makes it slow, it's installing another ROM. Having a rooted phone doesn't necessarily have any performance impact... just opens up a few things for me. Interesting. Thanks! Unfortunately I've already encrypted so now I have to find that thread about how to decrypt lol.
Thanks!

Google's Android Encryption - what a joke

So, I accidentally encrypted my device when I booted a kernel that had "force encryption." Ooops. When I rebooted, it immediately started encrypting. (No prompts.)
I tried to decrpyt, but it kept asking me for a password (which I never set up) and then would say that the password was correct (no matter what I typed), but something is corrupted in my data... and that I had to factory reset.
Sure. Bite me, Google!
Steps to recover:
1. Power off
2. Boot into the bootloader
3. Boot into TWRP recovery. TWRP see's all my data fine and doesn't ask for a pw.
4. Backup the phone.
5. Use adb to pull the backup off the phone.
6. Go back into fastboot and run: fastboot format userdata.
7. Boot the phone normally (with a kernel that doesn't force encryption.)
8. (the only reason to boot here is so that android creates the proper /data directory structure.)
7. Back into TWRP...
8. adb again to push the TWRP backup back to the phone
9. Restore the backup made in step 4.
10. Reboot again. Success. Done. Everything works fine and I'm not encrypted.
So much for security, Google. Pfft...

Forgive my ignorance, I am not yet a n6 owner. What, are the disadvantages of encryption?

Also due to the extra number crunching overhead, more battery burning.

I see how that is a negative. I'm surprised there isn't an easier way to disable encryption. I expect by tbe time I get one early next year some awesome dev will resolve that.

The point is that encryption has some negatives, but NO POSITIVES. What is the point of it when its so easily bypassed?

Encryption does have some positives, such as more protection of your data. How you describe and what you didnt doesnt show it as having much positives though
You claim it is worthless, because you could use root access and unlocked fastboot to push and pull data and all that, but can you really do all that so easily and get by the encryption without any root access and a locked bootloader? What about a not yet authorized ADB and you cant get into the device because it is locked and encrypted (in this scenario we are trying to break the encryption, not just go into the ROM and hit accept). I think everything is easier when you already have things unlocked and full system access.

Seems pretty secure to me. By the time you got to where you wanted to be, all data on the device was gone.
Mission: Accomplished.

The ONLY requirement to repeat my steps is either an installed custom recovery or an unlocked boot loader.
I'd agree with your argument if google allowed a non-encrypted fs if/when a boot loader was unlocked (which would be simple as /data is formatted on unlock anyway.)
Instead, google forces the encryption unless you swap boot partitions
Who's to say that the boot loader lock can't be worked around by someone determined? We haven't tried yet for the simple reason that the effort seems futile when we can so easily do it with fastboot. However, boot loader locks HAVE been worked around to boot custom recoveries on other devices such as Samsung and LG phones.
Once your in recovery, as I explained above, all the supposedly encrypted data is accessible.

It can be bypassed because you are using the default encryption key. If you set a pin or a password it changes the encryption key and you need to enter that in recovery to access the partition.

No positives... Lol

How many "typical" users will set a pin or password? Those same users, if they are concerned about data security, would be manually enabling encryption already.
Google (and Apple) came up with this "great" idea to force encryption on by default (and, at least in Google's case, make it the ONLY choice without modifying the system boot partition.) They claim they did this to protect data. What protection is there if Google allows the "typical" user to use the "default encryption key" and it's so easy to get the data even if "encrypted?"
I think what I'm getting at here is that I was extremely disappointed that it was so easy for me to get at my "encrypted" data using back door methods. I suspect that MOST people won't set up any extra keys/pins, and will allow the default key. They'll see that the device is "encrypted" and feel some FALSE sense of security. In fact, those people are facing a performance penalty of some degree in order to have that FALSE security.
Here's how I think Google should have done things:
1. First and foremost, don't use software encryption. Require the encryption system to have some form of hardware acceleration.
2. Instead of 'forceencryption', the fs manager should default to encryption ON if the bootloader is locked, and default to OFF if the bootloader is unlocked. The result would be that unlocking the bootloader (which nukes the /data partition and causes it to be reformatted) would start with an un-encrypted userdata partition. (The user could still enable encryption.)
3. In conjunction with #2, if there's no encryption key provided by the user, then DON'T ENCRYPT. I honestly believe that a false security is WORSE than none at all, and apparently the "default" encryption key is all but useless.
On the other hand, I hope my first post in this thread helps some user (or dev) who accidentally encrypts their filesystem while playing with kernels. Up until then, it was believed that once the userdata became encrypted, there was no way to reverse it.

Keep in mind, we XDA users are not typical users so of course we could figure this out. Secondly anyone even remotely interested in security has a password on their phone. Lastly, a question, does encryption prevent people from plugging your phone into a PC and seeing your data?

A counter-question: Who (or what) is google trying to "protect" us from with forcing encryption on?
No, encryption doesn't seem to block normal MTP access. Basically, an "encrypted" device (with no password), once booted, appears the same as a non-encrypted device (just a bit slower on data access.) The portion of /data presented as the "internal sd card" is accessible via MTP regardless of if encryption is on or off. (other portions of /data aren't accessible via MTP.)
With adb functional, unix permissions will block quite a bit, and once you add root to the mix, the entire phone can be accessed. (selinux probably introduces more restrictions, but I'm not familiar with them.)
Again, that leads back to the question of just who google is trying to protect us from. If the phone is encrypted (with no password) by default, and can easily be decrypted if no password was provided, then what good is the encryption? Why suffer the overhead of encryption when it doesn't serve any effective purpose?

TWRP tries the default password. If you had changed it, TWRP wouldn't have worked at all.
That was not a fair assessment of the encryption used on Android.

I actually don't think it's a big deal especially since you didn't have a password. Encryption without a password is like a door without a lock.
Also I'm assuming that once a password is active that MTP will be disabled without said password?

Again.... The point is that android is forcing encryption on even without a password. I KNOW I have no password, but if having no password makes encryption useless, why FORCE it to be on?
Sent from my Nexus 6

I think it's better than the current, if you encrypt you must use a password 24/7 mode. I prefer it this way because it's currently how I use my phone. I have a pin when I feel it's necessary (work sometimes, phone charging on a table, bar hopping, etc.) or basically whenever someone might be able to access my phone without my noticing. Otherwise I have my pin off. This works almost exactly how I've been wanting it for years. As long as when my pin is active people can't plug my phone in and view my stuff.

Samsung Knox VS LG Gate..?

Hello, on my Galaxy, the encryption function is gone and i was told it's because i rooted the device. Other function aren't working and few troubles comes in. I need to know if this is the same with the LG G6. Let me know, thanks

You can root LG G6 without losing any function, you van even keep encryption (although there are some problems with the recovery)
I'm not sure if you may not be able to see DRM protected content, as I've never used it

Actually, i said wrong : it's not that encryption is gone, it's here. What's gone is the option to have your pattern/pin asked during boot. That's a security i can't live without. So after rooting, is this option still available on the G6 stock rom (wether it's nougat, oreo..)?

On G6 if you set a pattern, you need it to unlock the phone after booting, always. Also, there is another extra option (see image)
I would say that the option is still here on unencrypted phones, but I can't confirm 100% since I have the phone encrypted. (on nougat)

Failing installing TWRP with Only Official Released Binaries Allowed

When I try to flash the according TWRP tar I get an error on my tab5se, it says "Only official released binaries are allowed to be flashed(recovery)
And Odin says "Fail! (Auth)"
I got no clue where to go from here.

When that happens it means you skipped a step, usually this means you didnt flash something and boot system to verify OEM unlocking is still on, or atleast thats my experience.

Hi XDA Forums,
I SOLVED THIS ISSUE:
All we've to do it to turn the phone on and fulfil these 3 requirements: All these 3 requirements can be found in the settings of the phone (Hereby I'm talking specifically about Samsung devices) and for mine it's Samsung Galaxy S9+.
- Enable Developer Mode, enable USB Debugging.
- From the same developer option, enable the OEM Unlocking (however may require reboot and reset).
- When the device reboots, turn on the device, go to the phone, go to the phone's settings and change the date manually to 2 August 2019.
Once you've change the date which is the last step then you can go back to the DOWNLOAD mode and install your demanded files (Recovery etc).
Thank you XDA.

I got super excited and immediately wanted to test it out but I still get FAIL in Odin when I try to flash TWRP and "Only official released binaries are allowed to be flashed (RECOVERY)" at the bot left in Download mode under all the text. Weirdly enough though, every time I change the date and restart the phone, it goes back to 28 June 2021 (this may be when I tried installing the stock firmware again but it didn't work either... why can't I just connect to the Samsung servers and automatically get the correct version for my phone, which also doesn't have stuff like jackpotlte in the description... I know I can get the correct firmware from sammobile but I feel like it should be more REAL )

Was the wifi turned on when you changed the date? Please Turn the wi-fi on, and then repeat the same requirements I mentioned above. When you're in Downloading mode install TWRP and IA it will be done.
It will definately work out, It was showing me the exact same issue but then I changed the date, powered off, booted it into download mode and installed the TWRP and even setted up the ROM (Noble ROM 1.5 By AlexisXDA). Also once you change the date to 2 August 2019, and you confirm it's changed. Then you have to turn the phone off and boot it into download mode (dont restart) but download TWRP via Odin and boot into the RECOVERY MODE directly.
Also if OEM unlock option is not being displayed in DEV options, changing the date to 2 August 2019 will show automatically unhide the option. The point when TWRP will be installed successfully, still don't let in boot to the system, go to the Recovery mode) i.e new TWRP.
Try to repeat the methods with the WI-FI on and let me know here again.

2 August 2019 doesn't always work. To find out what date you should change to, go to
"About Phone" and search for Android Security Patch Level, at the very bottom of the list.

Have seen such messages in the past but don't remember the exact sequence of steps.
Always try flashing the vbmeta file from Odin whenever you get an official error. If error still persists, then flash TWRP once and then the stock recovery.

i'm stuck while installing vbmeta with odin :
<ID:0/003> vbmeta.img

Usually you can't flash your device with custom os using Odin directly, you need at least a recovery mode like TWRP, the first thing you need is TWRP recovery for your device model, then install it in your device using Odin toolkit, after that you gonna remove the nand from your device by deleting system data using TWRP, but be sure you already had the Firmware galaxy tab S5e in your PC in case you want to use your tablet again, after deleting sys data, cache...get an SD card (at least 4gb) and put the custom os in the SD card, then put it in your tablet, and select install option in TWRP, select the custom os, and start installing the os.

Hi XDA Forums,
I SOLVED THIS ISSUE:
All we've to do it to turn the phone on and fulfil these 3 requirements: All these 3 requirements can be found in the settings of the phone (Hereby I'm talking specifically about Samsung devices) and for mine it's Samsung Galaxy S9+.
- Enable Developer Mode, enable USB Debugging.
- From the same developer option, enable the OEM Unlocking (however may require reboot and reset).
- When the device reboots, turn on the device, go to the phone, go to the phone's settings and change the date manually to 2 August 2019.
Once you've change the date which is the last step then you can go back to the DOWNLOAD mode and install your demanded files (Recovery etc).
Thank you XDA.

LG G6 H872 Encryption Bootloop - please help

Hello,
I recently went through the ROOT process for H872 (T-Mobile version) and was able to install custom ROMs (PixelExperience_Plus_h872-10.0-20200326-2210-UNOFFICIAL & Havoc-OS-v3.7-20200711-h872-Official).
Every time I try to "Encrypt" the phone, phone asks for pin, restarts, shows android logo, reboots again and then gets stuck in bootloop (up to LG G6 ThinQ logo).
Only way to recover from this state is to boot into TWRP to format the data; and reflash everything.
Bootloader is unlocked.
Using TWRP 3.2.3 Nebula_Alph_20180813 (one from the root instruction).
Please let me know if there is a way to to enable encryption.
Thanks!

Unfortunately force encryption won't work in Custom ROMs. That's why I am on stock

Thanks for the reply.
Yes, looks like you are correct.
Wonder if there is a ROM with default encryption.

Maybe Fulmics lol, But I dont know if there is version for H872. And Fulmics is outdated. You can try to debloat Stock ROM. Put Nova or other launcher

Thanks for response.
Anyway to hide or bypass the encryption status ?
Stock Image = Encryption works but outdated security patch
Custom ROM = Encryption doesn't work but updated security patch
Not sure which is better... both have some risk

Encryption helps when you lost your phone, without passcode you cant access data
New security patch - helps in app or ir OS security, it harder to hack or to use holes in software to get access to various data when phone is use.

So in your opinion, encryption is priority over security patch?

For me encryption is priority, because I have sensitive data on a phone: banking app, email client and so on
