[Q] Deactivation of Encryption - G4 Q&A, Help & Troubleshooting

Hi there,
I'm just asking, if it is possible to disable the encryption, once the phone is encrypted?
On my last Nexus 5 this wasn't possible, but on other phones there is this option.
Would be glad to see some helpful answers

The only way to remove encryption is to factory reset. Some phones (I think only ones with Intel chips) use the CPU for encryption which can be reversed without resetting. The G4 uses software encryption therfore can only be undone by a factory data reset which will cause you to lose all data, pictures, messages, etc. Pretty sure it tells you this when you choose the option to encrypt.

I'm running the stock software on my LG G4 unrooted and all. I noticed that after I encrypted the device that if I go into the encryption setting, it says "Decrypt Phone". Have anyone tried this, does it actually work?

[Q] Aindroid Pre-configured Anti Theft Software In Cooked Rom ?

Hi everyone. I have recently been the victim of theft for my nexus 7. I had the device locked with the pattern so there is no way that the thief could get into it unless they do a software reset from the recovery mode. The thing is, either way there is no way i would be able to recover it because if in fact they do a factory reset my lookout security would be uninstalled and my nexus would be lost forever, also if they can't get through the pattern and find a way to connect to Wi-Fi, it will still be lost forever. I have read about installing lookout in the system/app folder of a rooted device so its not easily uninstalled by normal means or factory reset. But do you think it is possible to have android lost and lookout pre-configured and installed in the system/app folder so that even if the device is factory reset, the credentials will remain?

I am thinking about this same issue... how do I make Androidlost app factory-reset-proof? I'm pretty amazed that this serious issue hasn't been answered yet in all those threads I searched regarding Androidlost.
As I understood it's possible for any rooted device to put an app in system/app and it would survive a factory reset, but the question is about the setting of this particular app, and I would be very grateful if someone who managed to do this successfully will share this step-by-step
Thanks

[HELP] Fingerprint Scanner and Backup Password no longer recognized.

It seems that about 15 minutes ago my Fingerprint (and my fiance) are no longer recognized. It also would not take my backup password. The only way I could get into my phone was through the Android Device Manager and reset my password.
After resetting my password with ADM, I went to go change my fingerprint in my phone (because obviously it doesn't like the one stored in there now) and it asks me for my password (since my fingerprint no longer works) and this keeps saying it is incorrect.
I don't know what to do now other than factory reset my phone.
Does anyone have any other suggestions?
You're correct. Factory reset; unless...
I thought my original fingerprints were better recognized after flashing another ROM; broke the sensor and default fingerprint password. Not accustomed to internal memory, I wiped everything but external sdcard and tried to restore the nandroid; embarrassing to say, the nandroid was gone.
You might try restoring a nandroid. Don't know if that works but I'd like to know. I had to factory reset. Per Samsung, nothing to do but that. May be locked away in Knox for theft protection.

Thing is, I haven't even rooted my note 4 yet! I am waiting for a method that wont trip knox.
I don't understand why this could have happened on stock - Makes me worried I got a defective device.
That's a mystery to me. There is also a change fingerprint password in that setup screen. If it rejects that too, factory reset is the only option I know of.
May need to exchange the phone. Keep that in mind if you're inside of 14 days of purchase agreement.

Yeah that doesn't work either.
I hope I can still exchange my device - It's been almost a month I bought this phone 10/17/2014 - Will they let me exchange the device?
Still under warranty. It's just they may make you wait on the replacement. Depends on where you got it.
best route is to get a replacement, seems the device is corrupted somehow

No, its been about a week since it happen. You can setup up a Samsung account on the phone to backup your texts, phone call logs and bookmarks. Then sync back to your phone after reset.

try odin flashing the firmware, others that were rooted, it fixed the issue, I know ur not rooted, worth a shot...
mine got messed up after rooting, I could not get it to work, even after flashing the firmware, but others have had success... try it, wont hurt any and won't delete ur data.
Yep happened to me as well.
Interesting thing is the password works on the lock screen but not in the settings menu.
Odd.
I had this same problem. The only way I was able to get the finger print scanner working again was by doing a factory reset. I then restored all of my apps and settings with Titanium Backup. All is good now. It sucks setting everything back up, but factory reset works.
Hello everybody,
I have xposed framework installed on my rooted Note 4. I basically uninstalled xposed and my fingerprint scanner recognised me again. I then reinstalled xposed and it was still working.
If you're not rooted this won't work for you but can someone with a rooted phone try installing xposed framework and see if it fixes it for you?
Thanks!:good:
I have the same incidence after restoring a nandroid backup to downgrade from LOLLIPOP to KITKAT, I've tried installing Xposed Framework Without Sucess.
I was able to unlock the screen using the google account and afterwards removing the lock screen by fingerprint.
When I try to change the FingerPrint asks me for the password for securty account and doesn't work (in locked screen worked fine).
So I'm afraid I'll have to do a full restore if there's no any other way to reconfigure the fingerprint scanner

If that nandroid backup is NIE, you'll need to wipe and Odin NK2. If it's NK2, try just wiping all user data to fix the finger print scanner. Password is not recognized is the indication that suggests one of the two solutions.
Installing Xposed won't fix that but temporarily uninstalling and clearing various apps' user data has helped. Personally, I've seen that work on health services and s health. If you need Xposed, you'll need the secure storage module. Just search secure or secure storage in the Xposed download search engine.
Locked out or private mode fingerprint and backup password don't work
So I'm locked out of private mode fingerprint and backup password don't work so I was wondering if I were to clear my credentials by encryptin device will it reset my backup password so I can access private mode or is there away i can backup my pravite mode files even tho I can't access them so i can do factory reset if that will fix it so i can use and access private mode with my files also can i find my private mode/ hidden files in my files on my note 4

Have similar issue after flashing a Tekxodus URV6.6 .. restoring data from a nandroid backup from Texodus URV6.5 which had all my apps installed.
I guess lesson learned is to make sure to disable the fingerprint security and wipe registered fingerprints before doing a Nandroid backup.
P.S.: for some reason the fingerprint backup password doesn't work

Thank you. I'll try it later .. I already wiped data and restored a Nand backup of the a clean Tekxodus URV6.6, luckily I have a full Titanium backup of everything (including call log, text messages ..etc.)
Btw, this Dual MicroSD reader is the best $10 i spent in my life it comes in handy once you pop a 64GB MicroSD in it, to use in TWRP for Nandroid backup, or to store a backup of Titanium Backups.

[Q] No Usable Options to sign in

Galaxy Tab S T-700 Lost unlock options
I have what seems to be a new one....The fingerprint scanner no longer boots at startup, The Alternative Password claims that I don't know it and I can't find the option to sign in with Google. Any suggestions????
I hadn't altered the software, Everything is still stock. I have VERY limited function thru a guest profile which will not allow any new apps nor access to most of the apps installed under my profile.
How about some kind of remote access?? Bypass the lock screen? I do have the right fingerprint, and the Alt PW ( I think, 90% sure). I have Team Viewer on everything else. Debugging is enabled. I have a good Google account. I also use Last Pass......
I'm another desperate noob. Please help.:crying:....
Try vol +home+power with the tablet off. Reboot into recovery, wipe data,cache and reboot. Second one odin 3.09 plus stock firmware from sammobile.com, boot in download mode and flash the firmware. Metod one will make you lose all your data, method 2 maybe will save your pesonal files (pictures, etc). 3rd method...samsung repair...you need proof of purchase , box and all the accesories. Good luck
Did you set up FIND MY MOBILE in Security settings. If so you can use it to unlock the lock screen with a code.

Search on youtube on how to bypass lockscreen before you factory reset.
Much Thanks!
In that I was "just playing" until I had the intestinal fortitude to root I went ahead with the factory reset.
Have any of you seen the loss of a sign in method before? Factory reset fixed it.... I wish I knew what caused it...
Threads again!

Not so very desperate noob....

How does security and encryption defeat someone just booting into recovery?

Regardless of device encryption and fingerprint scanners and the like, couldn't someone just get your phone, boot into recovery, and factory reset it? Wouldn't that undo any security you had on device?
Yes but the actual files have been encrypted. So while they can start the device fresh and use file recovery tools to "get" the old files, they are useless.
And they would be useless to everyone after that, even you? I guess that would be pretty good. So you encrypt to protect your user data, and you fingerprint lock to make sure nobody can ever decrypt, even if they factory reset thru recovery, which will get past your fingerprint scanner but not previous encryption. That right?
Actually since lollipop you must log out of your Google account before a reset. If you just factory reset you well still have access to the device to track it out wipe your account from it.
I could be wrong here, but if you have stock recovery, a factory wipe can only be started in the phone's settings menu. If you have twrp installed, a wipe can be started with out being in the phone, but you need a password to start it.
If you do wipe the phone, it is still useless as you need the persons gmail username and password to complete the setup, so the phone is useless to all other users bar the user of the phone.
I think you can factory reset from stock recovery.
So I don't get it. I thought user data was encrypted from phone, i.e., the internal storage. If I factory reset, I don't need a Google account to start the phone up. So then couldn't I access the internal storage data with a file explorer?
You have to authorize the phone to sync with your computer so you can not get on that way either. If you do not authorize you can not push adb or anything else.
As km8j said, yes, you can factory reset the phone, but you won't be able to recover any of the encrypted data. That's why before you get rid of an old phone you should encrypt (if it wasn't) and wipe it.

Thats not quite right. If you factory reset your phone, you do need a google account to complete the initial setup wizard. The only exception is if the user releases it from his or her's google account so it can be sold on.
But yes to complete the instillation it will ask for a google account that has been authorised and wont continue until it gets it. This happens automaticly the first time you sign in to play store.
Also factory reset will fully wipe the phone, brand new out of the box. It also wipes the users data, so if you were able to get on the phone, there would be no data to access. I really do like the way google have thought about it. Also I never keep anything on the phone that I would consider critical.
A lot of inaccurate information here. You have been able to skip that Google account setup on all android phones for the past few years. Also in basically any file system, when joy delete a file, even formatting, the content is not deleted. So while the information is not there at face value when you wipe the phone it can easily be recovered without encryption.

Yeah, that keeps confusing me. I have activated so many phones without inputting a Google account. It says "skip" right there on the screen!
Didn't Google introduce the security features with the Nexus 6 and 5.0? It locks the phone to your google account even after a factory reset but requires compatible hardware.
I haven't seen it mentioned with this year's devices but when setting up a pin on the 5x I believe it asked if I wanted to enable that feature.

No. If your data is encrypted, no one can access it without your decryption key. As for access to the device, if you had set up a Google account on the device, and had a lockscreen password/pin/pattern/etc., then no one else can use the device other than you unless you remove your Google account and lockscreen password before you factory reset. This was a new feature introduced with devices that sold with 5.0+

With the stock recovery, you can reset either from within Android or from within the stock recovery.

Yes, you can skip Google account setup. However, IF you do set up a Google account and a lockscreen password, THEN you cannot skip the Google account setup on that device after a factory reset (if you hadn't already removed the account prior to the reset).

Question Data restore after unsuccessful Android 12 update, bug 12 rkq1.211119.001, help is needed :(

Hi, I don't know if it's the right place to ask for help, but I'll still try.
A couple of days ago while travelling I updated my OnePlus 9 Pro with the latest update of Android 12 not knowing that update was apparently quite buggy as I found out later. Previously all updates have always run smoothly on my phones, so I wasn't really cautious about it. As a result after update phone didn't work anymore, it started always to vibrate after giving sim card PIN kinda trying to start (similar to the sound of whirring hard drive), but it couldn't go beyond the home screen's wallpaper. As I needed my phone, I had to choose "Format user data" under Wipe data from the boot menu as there weren't any other options under Wipe. I got a working phone after that, but I lost all my data.
So the question is: is there a way to restore videos and photos from the gallery (my photos weren't synchronizing to Google Photos) after this formatting? And more precisely, eg. by using DroidKit Data recovery tool I can perform only quick recovery unrooted, which doesn't find any files from the gallery. There is an option to perform a deep recovery, but for that I need to root my phone. Rooting apparently requires bootloader unlocking, which most likely wipes all phone data anyway without possibility to restore.
And more questions: would a deep recovery even find those gallery files, if the phone would be rooted? If bootloader unlocking wipes all data completely, so it wouldn't be possible to restore any data after that for sure? Is there an option to perform a deep scan without a phone being rooted? Is there an option to root without bootloader unlocking? There are some apps, which don't really do automatic rooting, and they aren't trustworthy, despite they say that they can root phones in seconds.
I definitely have learned from this recent experience, and I will do better in the future.
I think most likely it's not possible to restore my photos and videos I lost in this case, but I just had to ask to make sure, there are no more tricks I can use... Any thoughts? Thanks!
I would think there would be an app in the app store that would recover your photos and videos without root since they are to located in the root drive. It may take a few tries to find the right app. Good luck. That is why I routinely backup everything on my internal storage to the PC just for this reason.
Your storage is encrypted. There is no way to recover the files as the factory reset generated new keys when wiping the storage. Sorry for the bad news. Make sure to make backups before taking updates in the future is all anyone can suggest.

I've tried many of those before, but they don't see gallery photos nor videos at all after phone factory reset, though they claim they can do that. What these apps can see and recover in my experience are call history, documents, audio files, sms (all of these things were recovered anyway from the phone backup), photos and videos from Whatsapp (which I don't need as its' chats were backed up before that update). Some of them offer a deep recovery (don't know what a deep scan would find in the end), which requires phone to be rooted, and that requires bootloader unlocking, which will wipe storage for good anyway, so basically all those apps are useless.
