[Q] Factory Reset

So I'm rooted running JT Super Clean (DL09) and adrynalyne 12/30 kernel.. I know if I go into CWM and wipe data/cache it will erase everything on my phone resulting in me having to intall a new ROM, but what happens if I do a factory reset? Will it erase my ROM and put me back onto the stock system or does it just erase user apps/settings leaving me on super clean?

Doing a data wipe/cache wipe won't render the phone with no OS. It will do the exact same thing as doing a factory reset from within the OS will do. Which is erasing all user data, such as downloaded apps, contacts, sms messages, etc. Now if you were to go into mounts and storage in cwm and select format system, then you'd have to flash a new rom.

[Q] how to flash roms without losing data n files?

Alright guys I feel very nooby asking this but this is my first device that doesn't have a sd slot. Is there a way to flash a Rom without deleting the download and titanium folders?
My steps prior to flashing are
Wipe data, cache, n dalvik
Flash Rom
Then wipe cache n dalvik again
But if I wipe data then the Rom zip would be deleted before I can flash it?
Please help me on this thanks!

Hi,
Make only wipe data/factory reset, wipe cache partition and wipe dalvik cache, tat's all then flash your rom and reboot.
Don't wipe anything related to sd card/ext sd card or internal storage so you keep all your files in your "sd card" intact.

This won't happen on your LG G2. Even when using CWM you can see it is looking for an external SD card in the command line when doing a Factory Reset. You're internal SD card is never touched.
When you flash a ROM just:
Factory Reset
Flash Rom
Obviously make a backup first if you're worried, and you may need to flash Gapps depending on the ROM you flash.

understood, thanks guys

[Q] About using / wiping using TWRP

Hello people. Just wanted to ask how is the right way to wipe when flashing a rom WITHOUT losing the rom (wiping internal)? In CWM i just factory / reset data then thats it then clear cache and dalvik cache. In TWRP do i just need to swipe when the screen says "Most of the time this is the time that you need" when i will flash rom? Thanks for guiding!

anyone?

1. factory reset
2. advance, wipe system
thats all for me, works everytime... just make sure to wipe cache/dalvik after flashing zip files be it roms or gapps or whatever :good:

The default "most of the time" option is a fresh reset of the phone. it wont wipe the ROM itself, but all the data will be lost and you start over. Wiping system will remove everything, a ROM must be flashed after wiping system.

So before i flash a rom i wipe the "most of the time" then advanced format system? right?

true that... sorry for misleading initially, format system only applicable if you wanna have clean install of new rom

No need to use format system unless you are installing a fresh ROM. Format system will remove everything from your device (other than sdcard info and all that). So you get a clean slate.
If you just want to flash an update to the same ROM you can either 'dirty flash', which I usually just wipe cahce/dalvik then flash the ROM and reboot, and you save all your user modified things, or you can wipe system and install the ROM. You lose everything that way so make backups.
Usually there isnt much need to factory reset unless you're having an issue with something. What is it you're trying to do?

I wanted to flash a stock based rom. Thank you.

Blisspop: updating without wiping data

Hi,
I've recently done a succesful flash of Blisspop after a full wipe.
Now I want to update, but I don't want to do a full wipe. Simply installing the zip on-top gives a permanent booting screen. Can you update without starting from scratch?

Did you wipe cache & dalvik after flashing updated zip?

I did not. Is that the only required extra step? And will I lose data if I do so?

No, you only lose data when you wipe the data partition
In recovery, you'll see different named partitions, cache, dalvik cache, system, data, etc etc
If you wipe System, you wipe the ROM
If you wipe Data, you wipe your user data
Caches are just temp partitions, safe to wipe any time, only side effect is a longer first boot as Android needs to re-cache everything
But yes, you do need to wipe the caches when updating to a newer version of the same ROM/Droid version, and no you won't lose your data
Here's how I do it:
Wipe System
Wipe Caches
Flash new ROM
Flash new Gapps
Flash SuperSU if needed
Wipe Caches again
Reboot
Result = New ROM with no loss of data
That's a clean flash, a dirty flash is how you did it without wiping System
If you are moving to a newer version of android, or a different ROM, wiping data becomes more necessary, especially if the move is to an older version of droid

Thanks. I'll try it out.

Full wipe / clean install problems

Hey guys. I have TWRP 2.8.7.2 installed. I've been using Pure Nexus + Elemental X exclusively since December. This never seemed to be a problem before, but my last few flashes have resulted in sticky data. I go into TWRP, advanced wipe and wipe: DALVIK, System, data, Cache. Then, I delete Android from the internal storage and any other app directories that linger. Then I install the ROM, GApps, and kernel. Then, when I first boot my email shows up in the Google account setup. I thought "maybe it's saved on the sim card." But then I notice that when I reinstall apps, that they retain their data and my user data (for example, I don't even need to log into Runkeeper).
So somehow, despite performing a full wipe and clean install my user data is being saved. I know it's not part of internal storage so wiping that would only result in me having to copy my ROM files, music, photos, etc back over. So, where is this user data being saved and why isn't it being wiped?
Any help would be appreciated.

I'm not sure why this is happening, it's definitely word. But is there a reason you're wiping like this when updating the ROM? You really don't need to, you can just dirty flash the ROM zip when updating.

I don't like to dirty wipe. I guess it's the OCD in me that likes to start clean every time. I wonder if it's a bug in TWRP or something.

I used to do the same thing, until I realised I was just wasting time for no benefit. I don't think it's a TWRP issue, I was using that same build for ages with no problems. You could try updating to the latest TWRP though.

Try with "rm - fr" instead of regular wipe in options, maybe this works.

Are you doing a Factory Reset in TWRP to actually wipe the rom away? You list system, cache, and data (internal storage) but not Factory Reset.
Alternatively, are your apps reinstalling after signing into your account at Setup Wizard?

Try wiping system 2x. I had to do this on my S6. After wiping the first time and going back to the advance menu, System would then show up as 2 different partitions, System Read and System Write. I had to wipe the 2 in order to do a clean install. Although this is not the case for the 6P, I have made it a habit to do so. If that fails, you will need to adb the factory image.

He's already performing a factory reset by wiping the partitions individually.

That's what you would think, but why is this happening?
FWIW, I always TWRP factory reset, then wipe all the partitions he mentioned again by itself and have never seen this behavior on any version of TWRP.

I have no explanation for what's happening, I really don't know. I only ever use the advanced wipe menu, it's pointless performing the factory reset too.
