Try entering the bootloader i.e official recovery and try remove cache and dalvic cache if there is no option like this then do wipe cache partion .
If you have pc then try using easus mobisaver or wondershare toolkit to remove phone lock .
Or even odin for windows, run it and do remove cache or dalvic cache .

[Q] What is the default pin for the screen lock?

I just installed nightly 105. Because I had some battery problem, I wiped dalvik cache and then I found that my password to unlock the screen does work anymore. I've installed nightly for many times and this is the first time I wiped dalvik cache. Is there a default password for the lock screen? Or is there a way to bypass the lock screen? Thanks a lot in advance.
Update: after I rebooted a couple of times, suddenly the old pin worked again. Not sure why.

[Q] PIN Problem..Please Help!!!

Hello Everyone,
I just seriously dont know how it happened, but my mobile fails to recognize my Pin. Initially I had set up the pin lock and my pin code was 1234
Later i wiped the dalvik cache, and the battery stats, and after I rebooted it fails to recognize my pin password. So is there a way to bypass it....my phone is running on GingerDX v26 stock kernel. I will be seriously grateful if someone has a solution. Thanxx in advance

Officially corp via w8
yeah that is the last choice
if factory reset didnt work on your x8

[SOLVED]Forgot unlock pattern and adb won't let me login as root

Ok I'm owned.
For some odd reason I changed my login pattern then forgot.
I saw a few threads on here about disabling that security by using adb.
I can't login to my google account as my data is disabled, as I try to save battery life.
When I attempt to 'su' I get a permission denied error. I really don't want to wipe everything
just to bypass this crap. Heeeeeelp meeeeee!!
Thanks in advance..
I don't know if this will work, but here's what I'd try:
can you get into CWM recovery?
if so, do a complete backup, then wipe caches, factory reset, then boot, disable screen pattern lock, then try going back to CWM and restoring only the data partition?
If you try it, please post a follow up.

That will still have the lock in place. Are you sure wifi isn't turned on? Which ROM are you running? The Samsung based ROMs have a data toggle in the power menu. What is your process in ADB? Have you tried adb root?
root access is disabled by system setting - enable in settings -> development options is what I get.
Light at the end of a dark tunnel:
After feverishly searching google, there was a mention of wiping cache/delvik cache to show the data menu.
I did and then I enabled wifi.. Thanks for the help!

Changing Pin On Encrypted Device

I changed my pin last night, and everything was working fine. But this morning I tried unlocking (I accidentally used the old pin first) and neither of the two pins will unlock my screen. The new pin WILL decrypt my phone when booting the system and into TWRP, but not to unlock the screen. What the hell is going on?
I'm not sure why that happened to you, but you should be able to fix it by going into TWRP and deleting all of the files in /data/system that start with "locksettings." or end with ".key".
It was really weird. Nothing was working. Clean flashing (I'm using RR) kept giving me boot loops, so I ended up completely wiping my internal storage and re-encrypting once I set up my phone again.

This happened to me again, but deleting those files did the trick.
Is usual or am I doing something wrong (I never had an encrypted phone before).
I -wiped data, dalvik, cache -flashed new system and gapps -rebooted

My phone now bypasses the lock screen on reboot, after screen timeout or manually locking it's back functions correctly. Any fixes?
(sorry if my posting etiquette is bad)

Try going into Settings and removing and re-adding your PIN.

No luck, I also tried removing it, rebooting, and adding it back.
Are you sure re-encryption was successful after you wiped userdata? Also, is it asking you whether to "Require PIN to start device" when you change your PIN, and are you selecting that option?

Yes, the encryption appears to be successful, and I enter my pin before fulling booting.
It's behaving normally now, I'm not sure how many reboots I had before this happened. It was also after I re-added my fingerprints.
This is also a known problem of TWRP after restoring a backup. In that case it can be fixed by deleting /data/system/locksettings.db

TWRP locked

I tried installing a couple of custom ROMs in my Mi Max 2. When setting one of these ROMs, I set PIN lock to its screen.
After that, my TWRP is PIN locked as well. I must enter PIN to unlock my TWRP and to access it.
So the question is: How to unset TWRP lock? Is there in TWRP itself a command/option to unset TWRP lock?
(TWRP is official 3.2.3.0, ROM I using is EU Nougat.)

maybe u can try and flash twrp again, see if it resets and removes that PIN. also try other twrp versions to see if that helps.
you set encryption > then the lock is the pin to encryption and that has nothing to do with twrp .. it just trying to decrypt storage to work on it
try using that pin
if it didn't work you can always factory reset from twrp and it will recognize the storage.. provided that nothing valuable on the storage
also if you can boot to the system i had a pretty bizzare bug the can be useful for you
i installed reachability cursor app on xtended rom and force closing the app makes it lose the accessibility permission
after enabling it for the second time freezes the device and then if you force restart with power long press it stops asking for the code in twrp and while booting..
maybe specific to the rom but worth a shot if that's your case

I tried flashing same TWRP again as well as almost dozen of other TWRP versions for Oxygen. Nothing changed, I still must enter PIN password when entering TWRP and the same password when booting into system (from TWRP or from phone turned off).

I must enter same PIN password when booting into TWRP and when booting into system (from a) TWRP, or b) from phone turned off, or c) after resetting the phone when in system).
It is needless to say that phone screen is not locked in any way - by PIN/phrase password or by fingerprint. That leads me to conclusion that something should be (re)set/changed in TWRP itself.
Factory reset in TWRP didnot help. I will try to repeat the trick with xtended ROM and reachability cursor app.
you need perform format data

i wonder what will happen if you set a new pin in the current rom you running and made it ask for it at boot
then removed it?!

"...and made it ask for it at boot" - I already tried that. EU ROM has the option to PIN lock the screen, but it hasnot the option to ask a PIN at boot. So with EU ROM, at boot it will ask for same PIN as for the TWRP an after a boot it will ask for screen PIN as set in EU ROM.
