Hi everyone,
I don't know if this is a Tab A question, a Samsung question, an Android question, or a Marshmallow question.
I have an older tablet (SM-P350 with stylus) that I haven't been using a lot and I have forgotten the unlock pattern I was using. I am able to log in using the backup PIN, which I do remember, but I have to make several failed attempts to draw the pattern before I am prompted to enter the PIN. I'd like to start using the tablet more, but I don't want to have to do this every time.
I went to the security settings to change my login, but under "Screen lock type," it prompts me for my pattern, and after a failed attempt, it tells me I have to wait 45 minutes to try again! I am not given the option of entering the PIN. So I can't change the pattern OR change the screen lock type without knowing the old pattern! Does anyone know how I can use the backup PIN to do this?
As a last resort, I decided to do a factory reset. When I tried to do so from the menu, it prompted me for the security pattern!
I've tried twice to use the power and volume down buttons to reset, but I don't seem to be able to get to the recovery menu.
Now I can't log in to shut down and try again, because it's telling me I have to wait an hour!
And finally, one additional complicating factory is this: the tablet has been rooted -- not by me, but by the previous owner.
What can I do?

Hi, I recently flashed my SGS to I9000XXJVP, after flash, it keep on loop into recovery mode and prompt for password. I have flash my phone several time, this is the first I encounter this. Can someone help please. I have tried many combination, like 0000, 12345 etc.. but failed. I just can't figure out why there is a prompt for password, is it I set the screen lock pattern, but there is screen lock pattern, I do not set for password.
Please someone help, I can't use my phone now.
Thanks.
Just type any password several times. And phone reset all settings.
Hello everyone,
This is my first post on this forum and am seeking help from the community.
I attempt to encrypt the device with a 5 digit PIN. I get as far as the Android Encrypt logo screen however there is no progress bar or percentage complete. Once the phone's screen goes to sleep (2 minutes after initiation of encrypt procedure), I awaken it and I am immediately brought to the unlock screen to enter the PIN.
I enter the PIN and it brings me back to the Encrypt screen, again with no progress bar/percentage.
This basically can go on forever until I reboot the phone.
When I reboot the device it simply starts up as if the encryption procedure was never initiated. I enter my PIN and check the Encryption settings which show as if I never attempted/initiated encryption.
I then figured maybe it has something to do with the screen turning off so I went into Android debugging settings and enabled "Stay Awake". I attempted the encryption procedure again with the same results with then only difference being that the screen would not go to sleep which meant that it would remain in the Android Encrypt screen until I manually turned the screen off and on. Otherwise same exact result...its as if encryption process isn't starting and is only showing the encrypt logo screen.
I suspect it may be related to the CWM recovery image from information I gleaned from other posts involving different phone models/ROMs but I am not sure how to verify this or address it.
ANY HELP WOULD BE MUCH APPRECIATED!!
Thank you!

Had the same problem
I had the same problem a while ago and the solution that worked for me at the time is here.
But I haven't encrypted my phone in a while, so while I think the solution would still work, I haven't verified it.
I have just wiped and upgraded my Galaxy s4 to 4.4.2. I would like to fully encrypt my phone and use pattern unlock so I followed this article:
(just google pattern-unlock-an-encrypted-android-phone, I can't post URL)
But even though I have tried this multiple times and unplugged the USB cable (as mentioned in the article) as soon as I hit enter to start the encryption command the screen goes black on the phone and then after about 10min the phone reboots to the unlock screen and it is still unencrypted. I have tried following other articles too but they are all the same in terms of the command you run to encrypt the phone.
Any ideas? How can I get pattern unlock to work with an encrypted Android phone? Yes I know you can't do this via the GUI but then you need to enter a silly long password every single time you want to unlock the phone which is not an option for me. I don't mind entering a long password when turning on the phone but when it comes to unlocking the phones lock screen I would like to use the pattern unlock.
Any one else had any success with this on 4.4.2? Thanks!

Flash a different stock 4.4.2 . maybe its missing some files.
Hey guys,
So today I rooted my T580, 7.0 for the first time using this guide and I installed couple of apps I saw most people were using including some xposed modules.
Everything was working just fine til the moment I decided to add 'Draw unlock pattern' on my tablet to unlock it.
As soon as I put it to sleep and tried to unlock it, it just won't unlock, even though it recognizes the pattern is correct.
I draw the correct pattern, it hangs for about 2 seconds it puts the tablet to sleep again. I can't even shutdown the tablet because it asks me to draw the pattern.
What can I do to fix this?

Hold the Home, Vol down and Power buttons for about ten seconds. As soon as the screen goes black, switch your finger from the Vol down to the Vol up button. This should put you back into TWRP where you can reflash and start over. You have to be quick shifting from Vol down to Vol up or the tablet will boot to download mode instead of TWRP. If it does, then do the same thing again but switch faster.

If you have twrp installed its pretty easy to remove the pattern lock.

Thank you everyone, I was able to use the TWRP and restored a backup. I thought it was some app incompatibility but apparently none of the secure lock-screens work with SuperSU, they all mess it up and I end up restoring the tablet.
hey guys whenever i restart the phone it asks for pin or the password i setup and than only it will start the phone, why
is this normal, how to fix this
That's normal.... You'll always have to provide password or pin for the first time after phone reboots. Unless you select none for your lockscreen unlock method
My phone in the beginning asked every time I restarted but now it doesn't ask for anything. Is something wrong?

There's two levels of lock. One is the lock before android starts and second one after boot is finished.
If your phone isn't asking for an unlock password/pin it's possible you may have disabled it. You can enable the lock before device starts by going through the same process as normal but checking Yes when it asks the question. See my attached image for how the screen looks. If you select No you can apply a regular after boot lock.

Figured it out just after posting. But thanks a lot for helping.
Change secure start up settings
Is there a way to change secure start up settings aside from reset factory settings? Thanks in advance
