[Q] Hard Reset Options - Identical?

Hi all,
Have trawled the forums & net but, rather surprisingly, can't seem to find anything on this.
Just would like to know if there is a difference between the two different hard/factory resets (through the settings backup menu and using hardware buttons on startup).
I noticed on my old HTC1X that the former method sometimes resulted in some settings not being reset but not sure if that was a glitch or faulty restore.
Thanks,

Do you mean factory reset in the bootloader vs factory reset in Settings ?
if yes then Yes they both do the same thing, they delete your /data folder and leave the sdcard alone

Yes via the bootloader and in settings.
Thanks for the confirmation, have always been curious if the bootloader option was more of a 'thorough' wipe so to speak.

if you really want a complete wipe just unlock the bootloader .. that does a complete wipe of everything on the phone

Looks like you have the answer... But you are not ready to do it yet...
I don't have a solution for you, but if it was me I would backup as much as I can and factory reset or flash a factory image and move on.
Good luck...

SOLVED
solved using tasker > plugin > secure settings > camera enable
like you see in attach

OEM Toggle is shown but can't be toggled; phone unable to go into download mode.

Hello XDA, I hope that you could help me troubleshoot my Note 8 (N950F).
So it's been 7 days and oem unlock toggle has finally appeared.. The only issue is it is greyed out and unselectable.
When I got this device I wasn't able to see developer options by pressing build number (though I got the notification that it was enabled), I was only able to access the setting by downloading an app short cut for it via the play store and on initial launch it said developer options are disabled. But then second launch it worked. Idk if this is significant but maybe the country this is meant for disabled it? Regardless of the sim card being in/out the phone, it is still greyed out. Also, I was able to factory reset the phone through the settings after downloading an OTA (I did this in hopes of developer options being enabled about a week ago.)
I tried to boot into download mode but it seems I can't boot into it (following the steps only lead to a normal reboot, and when I select that option from the stock recovery or through adb, it only boots the phone up normally. I purchased the phone off of swappa, in brand new/like new condition. Any ideas? Thank you for your help.
Edit: added screenshots.

SM-N950F / DS here running Taiwan software BRI and I have the option maybe if you flash this firmware you'll get it.

Thanks for the answer! However, I don't think I can flash firmware because I can not go into download mode, which is needed for odin to flash firmware

That's weird I've never seen a Galaxy that can't enter download mode.

Exactly. That's why I'm so concerned.

Have you logout your Samsung Account and Google account？sorry for my poor English.:crying:

Do you use any of the KNOX stuff? Did you do any factory reset?

Can you "clear data" on "settings" app? this would make the "developer option" menu hidden again. Then re-show it by tapping build number numerous time again. Hoping that OEM is now editable.

Hi, could you solve this problem? My Note 8 has the same problem and I have not found any solution :llorando:.
I would appreciate it if you can help me.

Factory reset is not enough. Recommended is clean install, wipe at least system, cache and dalvik, then flash previous ROM. If it still doesn't work, flash KDZ.

First of all, thank you.
With "factory reset" I mean I made the following:
Code:
1. Boot into TWRP
2. choose wipe
3. choose advanced wipe
4. select: Dalvik/ART Cache
System
Data
Internal Storage
Cache
5. swipe to wipe
6. flash previous ROM
So it doesn't work. How can I flash KDZ?
The same way like LIneageOS?

Hey there. Your flashlight is not broken. Trying adding the widget to your lock screen. Or if you want to test type this in your dialer 3845#*405# and a hidden menu will appear from where you can test the features of your device. But if you reboot your phone they reset. I hope this helps you.

Hi there.
You're right.
I've flashed the new LineagoOS nightly and the Flaslight turns on for about 1 or 2 seconds and then turn out.
This happens every time i've tested it.
The code 3845#*405# doesn't work.
I see a message saying "USSD code running". That quickly disappears and then nothings happens.
It seems that I can't add the flashlight widget to lock screen.
any suggestions how I get the flashlight work?

Hey there the code won't work in custom roms. It is only for stock roms.It opens hidden menu. Custom ROMs take the advantage of your phone while it mat offer you a faster phone.Please revert back to stock ROM. Ik stock ROMs are slow.But it is much better to stay with stock ROMs with root and custom recovery and xposed.Check flash light once you flash stock recovery.
Hope this helps ?

First of all: Thanks a lot.

What means xposed? Some kind of app?
I've flashed D40520a_00.kdz ago but Flashlight also didn't work.
It "works" since I've flashed ne nightly...
If I flashed the stock rom all Preferences would be reset, right?
So why did flashlight not worked if I installed D40520a_00.kdz?

Hey take a backup of your internal storage.Then in Lg flash tool do a csc flash.Flash correct kdz file.
Try some Google play apps for turning on flashlight

OK. I try it once again.
I usethis guide to flash KDZ. Is it OK?

I've tested every menupoint and I found nothing.
With the stockrom I have no Torchlight symbol in quick settings (when you move from the top to the bottom where you can activate wlan, bluetooth etc.)
I add a torchlight widget to the homescreen. It turns on for about 2 seconds then turns off if I activate it.
The SOS-function works. Lollipop or KitKat stock. always the same result.
Is it possible to flash the complete smartphone.
It seems like there's a progamming block or some kind of settings that's wrong and that won't reseted with stockrom flash.

Download flashlight from playstore and test

it is always the same with every app.
The LED works for about 1 second than turns off.
Flickering works at all.

Try contacting lg service centre for a possible fix.Try flashing a bootstack or a custom kernel.I know they are not related to flash light but still trying is not bad at all.

Try wiping the cache partition in Recovery Mode. If that doesn't work backup your device and perform a hard factory restore.

Thanks for the answer. I did the hard factory reset and it still did not work. So I contacted Samsung Brazil and they asked me to send the warranty. Maybe it's the motherboard problem.

Yes if you already reset and tried flashing with Odin then it's likely a hardware issue. Hope they sort it out for you
