Ho Ho Holy **** what have I done?
I wanted to factory reset my device so opened twrp and did the usual. I kept getting the unable to mount error. After reading around I surmised it was an issue with encryption so I performed a data wipe thinking it would rid me of encryption. Disappointingly I was still prompted for a password on reboot but it doesn't recognise the password so I'm stuck at the login screen. I wanted to wipe the device so I could set it up for someone else as a christmas gift.
twrp 2.8.7.? lollipop 5.0.2
Thanks in advance.
Data wipe or a factory reset?

Are you asking if I've done either or suggesting I should try them?

I'm asking which? There is a question mark at end.

Hello,
As Google has decided to turn encryption on as a standard in the upcoming Android 5.0, I thought I would give it a test on my CosmicCM 5.4.
I started the encryption and it prompts you that you for a passcode that will be used from now on, so far no problem.
It started encrypting my device and it was running for some time(I left it alone for an hour) and reboots a couple of times.
After he's finished the annoyance came.
first you will have to type twice your password with a reboot, one time do decrypt your device the second time to enter your device.
Be aware that performance can be slowed through encryption, and it can negatively impact battery life too.
So I decide to go back.
The Problem: Once encrypted, you can't decrypt it easily.
When encrypting the phone android will tell you you can only decrypt it using a factory reset. Naturally you assume it's talking about the "Factory Data Reset" option found in Settings --> Backup and Reset and this works.
Now I wanted to try a rom (TW 4.2.2 based) and see how this worked and after installing and booting.
I got prompted to enter the decryption and of course this didn’t work anymore as there is no data for the password.
So I assumed you can wipe everything from your custom recovery mod (CWM, TWRP, or one of those).
Wrong! You'll get beautiful "can't mount /data" messages and more.
After some hard time I got everything working again, by flashing CosmicCM again.
The phone booted al clean again without asking for encryption and when you check the menu it also mentioned encryption is deactivated.
Trying the previous rom again just triggerd the encryption again.
So It seems that there is still somewhere a hidden encrypted protection that will be activated when I flash a different rom.
So be warned and don’t play with encrypting your device as you could brick it.
Didn't have time to investigate further on how I can remove it completely, but my guess is I have to redo all the partitions.
I was on the same boat a month ago

I wish you told me sooner
Did you redo all the partitions to get the encryption completely removed?

I think I had to wipe my data via Philz, CWM and stock to remove encryption.

Thanks for the info, will try to flash stock this week and see if this helps
So I backed up stock OxygenOS with TWRP, copied that backup to my PC, flashed the CM13 nightly to test it, wiped the device, restored original backup from TWRP.
Boots up, asks me for my PIN, this works and so it continues to boot Android.
At the lock screen it says 'Wrong PIN' when it's correct and it's the only PIN I've ever used on the device.
Does anyone have any suggestions that may fix this?
Thanks.
I had the same problem with unlock pattern, idk how to solve it without formatting internal memory.
but you can erase internal memory (factory reset) and your phone will reboot and be clean (wiped everyting including pin)

Yep it sucks, I'm trying to avoid that
This is a known issue with twrp. You should be disabling security (pin/fingerprint) before making a back up. There is a thread on here on how to get around it.

Good Evening to all,
As per the title says, I need help on how to safely resetting my OP5T to factory setting.
My phone is rooted. I don't mind if I loose the root access or not, I'm still going to root it back anyway.
I think I messed up some setting or whatnot on the phone and am to confuse to trace back what I did wrong.
If you guys so kindly guide me to where should I look to wipe everything to new, I'll be appreciated.
* some of the problem that I'm facing right now including "because an app is obscuring a permissions request, settings can't verify your responses" whenever I try to verify my computer rsa keys, microphone volume too low on earphone or headset as I already tried 3 brand new earphone and headset and the result is still the same.
Thanks.
Settings - System - reset options - erase all data (factory reset)
otherwise
Reboot into recovery(Hold power + vol-) - wipe with default settings
after process is complete perform first boot and then reboot and flash magisk.
EDIT: You could have gotten this info from google in couple of minutes.

Thank you the reply.
I did google first before posting this. It just that some people said that factory reset sometime just wipe the media but not the system. Some said factory reset on root will cause the bootloop. I'm just trying to make sure everything goes smooth.
But thank you anyway. Sorry for taking your time.

Go to twrp
There is a option of factory reset just swipe to do a factory reset and reboot to system
Or
Go to twrp / advance wipe / select cache , dalvik cache, data and swipe
Done

I want to do a factory reset, leave the mobile like when I bought it but keep the root of Magisk and the twrp
Hi everyone I had an unfortunate problem with my new Samsung Galaxy A72 and it is the following: Since I don't have a PC,
I can't get the phone into recovery mode for the moment to perform a "hard" reset and clean up the phone.
Is there a way to go into recovery without a PC or is it mandatory? Thanks to those who can give me an explanation.
If you are unrooted, the only way to reboot to recovery is with a PC. I think you can perform a hard reset within the settings in General management.

Thanks for the reply however, it is absurd that Samsung forces me to have a PC to do a Hard Reset since now I also do not have one.
They do everything to complicate life...you could do a soft reset from settings but it wasn't what i wanted.
Hello and thanks again for the explanation.

You are correct, Samsung does some questionable things and this is no exception.
By the way, the reset from settings is pretty much the same as if you did it from recovery since all it's going to do is delete the data partition without media (I think, can't remember). I believe when you do it from the settings, it reboots to recovery and wipes from there anyway so it's pretty much the same thing. I really don't know what you mean with a "hard" and "soft" reset though.
I would consider a "hard" reset as formatting not only data but also system and the rest of the partitions, which can only be done with either a custom recovery or doing it with Odin (which requires a PC)

hello thanks for the reply.
If I remember correctly the soft reset from settings ago (reset or reset settings), hard reset instead from stock recovery
wipe cache and data and dalvik ... I think
And having no PC for now I will do the one from settings, too bad, but this samsung puts a lot of difficulties every year,
worse then it will also be the fault of Android 11 I don't know.
Hello.
I have a problem with a phone, i working in service and i see the new phones Samsung A52s in recovery mode don't have factory data reset, only wipe cache. Any ideea ? without install via Thor?
Thabk you!
