[Q] Decryption password not working - Android Q&A, Help & Troubleshooting

I encrypted my LG Optimus G E970 using the option in cyanogenmod under security. It prompted me for a pin using a keypad, and I carefully entered a 4 digit pin. At the end of the encryption process, it rebooted and promted me with "Enter password to decrypt storage." Instead of a pin, there was a text box and full android keyboard. I entered my pin, and it said "Try Again." It did not lock me out at all for any amount of time no matter how many passwords I tried. I tried rebooting it, and had the same problem. If I leave the device on without typing in a password, it makes a clicking sound after a minute or so every ten seconds. I can't factory reset in TWRP because it can't mount /data. What should I do?

Hey i'm having the same problem, just got the same phone (LG optimus G e970) 3 weeks ago cause i signed a new 2 year contract, got it rooted and then tried to encrypt and it's not letting me in even though i'm sure the PW is right. someone told me LGNPST might work and i tried doing the steps and it was no good. Anyone have any way of remedying this problem? I have ATT and if all else fails i'll just return to the store to get the encryption off but will they give me any flack if they know it's been rooted? Thanks

Set the phone back to factory mode by LGNPSTing it. I had a similar problem with stock rom. Had to lgnpst it as recovery didnt helped flash new roms.

Did you ever get encryption working? I've been unable to encrypt my /data partition with the following ROMs:
BeanStalk-4.4.205-20140103-geeb
carbon_geeb-2014-01-04
cm-10.2.0-e970
cm-11-20140104-SNAPSHOT-M2-e970
purity_geeb_ota_2014-01-05
However, I am able to get it working with the stock AT&T image (ATT-Stock-E97020j).
The symptoms are the same: appears to encrypt correctly, however the pin doesn't work.

[Q] Enter recovery password?

So my daughter got a hold of my phone. "I think" she tried entering the password too many times. Now phone just displays:
Just my Background Picture and this message below.
"To unlock, enter recovery password"
______________________________
Under this message is a Emergency Call button.
I tried my phone password, google password, and Outlook password. All not working. After entering my password, and it is incorrect I get this message:
"You have incorrectly attempted to unlock the phone 1 times. The phone will now be reset to factory default" OK button. (DONT CLICK OK, Just restart phone by holding down power button)
I then just power off and restart. After restart -> Samsung logo -> Verizon logo, it goes back to the "To unlock, enter the recovery password" screen.
Don't want to go to factory default, Any help or suggestions???
Verizon Samsung S3
Verizon just pushed out the KitKat update to my phone last month.
NOT rooted, just stock Verizon ROM.
I can call this cell. I still works. But can't get to regular unlock screen. Always just goes to this Recovery password screen.
Do a hard reset.. no another way
Really... Is there no Default "recovery password". I don't remember setting one up. Any Google work around? I tried searching online, and I don't see anything about this "Recovery Password"... Is this new or do people just not get to this screen?
Well, if there is any Odin-flashable recovery for your phone, you can flash it and then pull important data using ADB. You can also take a Nandroid backup and then use Nandroid Manager to see if you can recover any more data from the ROM.
This will void your warranty.
Bingo... So if anyone is still having this issue, you DON'T have to do a factory reset. I finally solved it (at least it worked for me). Here's how I did it. You need a Google account setup already for this phone. Go to: wwwgooglecom/android/devicemanager (add dots, come on xda, I'm not a newbie -> join in 2009) I tried to Locate and I tried to Ring, they both worked, but you need to do this -> Click the LOCK icon. Then it will try to find your phone. If it does find it, it will ask for a NEW password to "LOCK" your phone. After entering your password, your phone will "LOCK" itself. (Even though it has been locked out already) Once that is done, I went back to my phone and try entering this "new" password I setup in the: recovery password location. It works. Good luck...
Not sure how to mark this Thread as Solved...
Bloody Legend!!
You wanted to say thanks mate.
My S5 has presented me with this screen twice, in the past week! The first time it wiped my phone (and SD card).
Happy New Year!!!

Going to wwwgooglecom/android/devicemanager doesn't work anymore. Now when you try that process, you will get a pop-up saying that the device is already locked and the new password you put in will not be used. You are still required to put in the old Recovery Password. I have wiped the phone and tried to find where one would put in a recovery password and cannot find it.
I contacted Samsung and they told me to use their system. Go to findmymobile(dot)samsung(dot)com and log in (assuming you registered). I logged in, went through the process to unlock my phone. I could see the notification that the unlock was successful, but the lock is still in effect. Samsung support said I would have no other option than to wipe the phone again. I asked how I could get support for the Android lock that was in effect, and they referred me to support(dot)google(dot)com. If you go there, and work your way through the menu, you find that the manufacturer of the phone is supposed to handle Android OS support.
So Samsung has added a proprietary remote unlocking feature, but somehow forgotten to disable the built-in one. Since they have that extra "feature" they won't support the default one.

Invalid/lost PIN for secure startup/ask PIN on boot screen

Hoping someone can help because my phone is completely unusable. I was in work yesterday and decided to restart my phone because the battery was draining and I didn't have a USB-C cable. It got to the "enter PIN" screen, and the PIN I've always used was invalid. I'm pretty sure I never changed my PIN, but I've used 15 of 30 guesses trying any number that I might have changed it to, and none work. I usually unlock my phone with my finger print, but that isn't possible because this isn't the standard unlock screen, it's the screen before the phone even fully boots up. It's not connected to the internet yet so I can't reset it via Google and there's no "forgot PIN" option.
To further complicate things, the power button on my phone doesn't work (though the finger print sensor still does.) The phone was in my pocket and got moist from sweat on a hot day, and hasn't worked since. So I'm not even able to get into recovery mode. I can turn the phone on by holding volume-down and connecting then disconnecting the charger. I can also get into "download mode" to flash firmware by doing the same thing holding volume-up.
I have my camera photos backed up, but nothing in my downloads directory is saved, nor any pictures received in text messages. I'm sure there's plenty of other stuff that's not backed up too. I hadn't enabled encryption. Is there any way to transfer files off my phone? I'm assuming no, especially since even "adb" doesn't see the phone in either download mode or the PIN entry screen. USB debugging was enabled, but it seems like it's only connecting in "charge only" mode.
I'm not even sure how to get the phone working again, even if I have to wipe it. Should I try flashing a stock ROM (it's not rooted or un-bootlocked)? What happens when I enter the invalid PIN 30 times?
Thanks for any help.
Edit: If it helps, it's the AT&T model, H820
think you must reflash the Rom with fatory reset option. not the best, but you have a usable devive again. Bad you cant root the device and delete just the two *.key files

What happens after 30th attempt to unlock Secure Boot?
I have forgotten the unlock pattern for my G5, which has been sitting in a drawer for the last couple of months.
What happens when I fail to correctly enter the unlock pattern for the 30th time? Will it clear the data and reset itself, if so, no biggy, or will it turn itself into a brick, which would be a biggy?
Regards,

It clears all data and factory resets itself. The only other thing is that you need the password for the Google account it was associated with, in order to use it after it resets. I think it's to prevent phone theft. I remember hearing you shouldn't try to change your Google password within ~3 days of resetting the device either, because it might not work.
Note that if it's the actual screen lock pattern you forgot instead of the startup/boot PIN, you can probably just reset it through Google's Android Device Manager website.
LG G5 SE H840 stuck on secure startup
Hi everyone.
I've tried to flash TWRP on my phone using fastboot and it seems to have worked, but when I reboot, my phone is asking for a secure startup code.
I don't have it because I don't remember setting one up... Each reboot uses 2 of the 30 try allowed and now I'm at 12 left.
I tried default_password, and some other things... not working.
I tried fastboot -w to do a factory reset, but it doesn't want to write "userdata" : "cannot flash this partition in unlocked state"...
Code:
Created filesystem with 11/32000 inodes and 4110/128000 blocks
erasing 'userdata'...
OKAY [ 0.609s]
sending 'userdata' (138917 KB)...
OKAY [ 4.361s]
writing 'userdata'...
FAILED (remote: cannot flash this partition in unlocked state)
finished. total time: 4.989s
For what it's worth : I'm french and the secure startup is in french... Is it because the initial stock rom that I used is still behind whit my settings ? Factory reset should have brought me back to English at least ?
Any help please ?
New problem, new thread.
I remember that I set a secure startup pin in my Lenovo TB3- x70L . But when I typed the pin the tab displayed incorrect pin . So I restarted it a black display appeared to enter the pin.
I tried many times typing the pin what I set . It shows all are incorrect pin . And after many attempts it says "your tab will be wiped after 7 attempts with incorrect pin".
My debugging is off ,OEM is off.(Initially).
But I some how activated debugging.
Pls help me guys if you can.
Same issue
Have you guys ever solved this issue? I am facing the same with my LG G5...
Hey i have a lg aristo 2 and forgot my lockscreen passcode i have tried multiple tips off the web and me and my fiance are both logged into her google account what can i do to get into my phone....
Lg vs087 g5
Had the same problem....Secure boot enter pin. After exceeding the 10 attempts it factory reset itself and went into setup.
I have the exact issue also on my LG G5 H830. it recognizes my fingerprint but the pin ive been using for years says its wrong pattern. I can only unlock my device with my fingerprint. f**king weird.

Is there anyway to bypass FRP?

it's been years since the last time i touch my Redmi 3, i forgot the password, so i just factory reset it with my twrp.
but i need to login with old email to verify my phone, i forgot which email, because i tried every email that i can remember i ever login into this phone but got denied.
i tried to full wipe and replace rom, but it's still the same prompt that pop up, Insert email to verify the phone. is there anyway to bypass this?
as far as i know, this feature is for miui Roms. flash a custom Rom and you never see this alarm again.

Pocophone F1 password wouldn't work.

Pocophone F1
security set to fingerprint and alphanumeric password.
every 3 days the fingerprint stops working and asks for password as a default security feature.
Last night it asked for password as its been 3 days since last used password. I am certain the password is correct and signed in several times before with it. I suspect there might have been a system update in the last 3 days. Now it keeps saying password is incorrect.
Forgot password option only allows erasing data and back to factory default.
Any help would be much appreciated.

if you have TWRP or any other encryption supporting custom recovery, reboot to recovery and then check what it asks for.
called xiaomi uk
I didn't root the phone or have custom recovery installed unfortunately.
called xiaomi uk customer support, they were saying the phone should give the option to reset the password via the google account but it isn't giving this option.
the phone is definitely connected to my google account. can see it there and was able to locate it and ring it from the computer browser.

I didn't install those unfortunately.
Did you associate your phone to mi account? She this happen to my girlfriend's phone and saw a bunch of cases while looking for a solution. Couldn't find a way around factory resetting.
I ended up doing the factory reset. I am sure it's a Xiaomi software issue because when I was initiating the phone again, when you set up fingerprint it gives this message:
"Remember your lock screen password. If you forget it, you'll have to erase all data on your device, including photos and contacts, and then set a new one"
This is exactly what I ended up doing other than the fact that it wouldn't accept the correct password. There is ways around it if you rooted your phone before this happened but in my case there was no quick solution.
Xiaomi should allow the password reset via Google account like other android phones.
Lucky I did have some backup via Google so wasn't a total disaster.
this is really bad. Im in this situation and i don want to erase my files as i didnt back up or used cloud. since yesterday looking for work around this screen lock issue, im using pocophone f1.
