[Q] Passcode changed during ROM flash - Android Q&A, Help & Troubleshooting

Hi all,
I have come across a problem today after trying out the MIUI ROM for my SII. I had quick go but decided not to use it, I re flashed the latest version of westcrips ressurection however when I returned to the lock screen my previous 4 digit PIN was not accepted.
I can only theorize that the previous PIN was overwritten or corrupted somehow. I am pretty sure there is no way to reset or discover android passwords. With the pattern lock there was an option to unlock your phone with your google account however I can't seem to find that with the PIN or maybe it has been removed from ICS westcrip?
Anyway, what to do? I don't really want to wipe everything and reset
Thanks,
Auzeras

[Q] SGS2 on O2 contract asking for a password in recovery mode

Hi,
I got my SGS2 from O2 yesterday, went to check recovery mode is working ok and it is asking for a password. Has anyone else on O2 had this? For the short time I had my SGS on Gingerbread I got asked for the same when trying recovery mode.
Just tried on my unlocked T-Mobile phone from CPW and it goes in fine.
Blue text, Android system recover (3e), and options to reboot, apply update.zip, wipe data/factory reset and wipe cache partition.
Also this was done on a rooted phone although im pretty sure i also tried it before rooting and it still worked then.
Password is your screen unlock password.
It turns out it is because I had the screen lock set to a PIN.
Yep, If you have either a screen lock PIN or password set the recovery rom prompts you for them (although if you set a pin it still refers to it as a password in the recovery rom which can be confusing).
However if you set a pattern lock then no prompt is given.
nice to know
Thanks for the info
I was sure my recovery got locked by the store I got it from ... (If its possible)
After replacing my Email.apk without any security and canceling the PIN all is well.

[Q] how to get/remove the pin on an unrooted phone?

Hi! I have an (annoying) situation here, i recently bought a phone (bottom), the phone has been wiped of all apps, however, the last person (the seller) didn't do a FULL factory reset, so his Google account is still the primary.
I know you can remove the primary account via factory reset, but there seems to some sort of PIN/password, you dont need a pin/password to unlock the phone (from sleep), the screen asking for a pin also popes up when i tried to apply a lockscreen password
Ive emailed the seller already, but he takes a long time to respond, and i hate to wait.
i know theres specialized hardware like Riff-Box, but this phones waterproof and i dont want to break any seals
Ive also tried to do a root, but kentai/japanese phones have tight security with a small amount of hackers (link to root bellow)
Anyway, my question is that is there anyway to get that pin out of the phone/disable/remove it WITHOUT rooting or cracking the case open
eg software hacks
ive already tried the ADB methods, which require a root, and i have a copy of SDK with proper ADB drivers if anyone has any complex suggestions
Phone
-Sharp SH-06D [normal, NOT the NERV edition]
-internationally unlocked by DoCoMo
-running an unrooted 2.3.5 and (obviously) stock ROM

FYI i have full acess to everything except the reset, password, and superuser/SU

Thanks! and sorry if my english are bad

Question: Changing the PIN/pass on Marshmallow

Dear Experts,
I experimented the last few days with a few ROMs.
I went for device encryption.
On Android 5 it always forces to set a password.
On Android 6 it is possible to use either a password or a PIN code. I entered a password first. After the encryption went through, I decided to change it for a code. This went flawlessly, till I restarted the phone. Then before loading the OS it asks of course for a password. To my surprise, it did not take neither the new code, nor the old password and I had to reflash the entire ROM.
Does anyone have an explanation ? As far as I googled, it should be possible to change the password... What did I do wrong ?

Got stuck with the pattern lock

Hello Gentlemen and Gentlewomen,
Well, I have a ZE554KL, with OREO 8.1 installed.
The phone is boot loader unlocked.
I use the fingerprint + pattern lock.
I know it is my fault, but I got the phone running for 2 months w/o rebooting, so all of suden, today the phone locks itself and ask for the pattern lock for "additional security". Well, after 2 months not using the pattern, just the fingerprint, I ended up forgetting it.
Now I am stuck. I cannot reset the unlock method neither via the phone nor the google device page. Is there anyway to remove the pattern lock or switch back to the fingerprint, without the need of wiping my data?
All the best.
