What should I wipe before I sell my phone:
Dalvik Cache
System
data
Internal Storage
Cache
USB-OTG
Well, assuming the person buying it wants an OS on there, you should perform a factory reset from the settings menu while the phone is booted. This should take care of the system and data partitions (I think it takes care of internal storage as well, but you can be sure by wiping internal storage in TWRP).
You could also just do everything in TWRP if you have a flashable zip of an OS (COS, CM, OOS, etc.) and a Gapps package ready. If you have those ready, wipe system, data, cache, DALVIK, and internal storage then flash the OS and Gapps and boot. If you did this, you just performed a clean flash and everything that was previously on the phone is now gone.

If I wanted to just keep the OS, would I wipe everything but System then?
Also, when I restart my phone, it still asks me for my encryption password. I thought after a factory reset, it would no longer ask me for this. How do I get rid of this? I want to leave whatever is encrypted, encrypted. Do I need to wipe something else, I am guessing?
Wipe everything on that list and just connect PC to computer and transfer gapps and rom via twrp and then flash. Completely cleans phone
Check first if your computer recognizes your OPO while in TWRP. If not, get yourself OTG cable and pendrive. Wipe everything and flash new rom, gapps, root perhaps via otg. Cheers!

Wipe everything *before* plugging in the OTG drive. Wouldn't want to wipe the drive containing the ROM.

I'll try to explain myself before people jump at me. I saw another thread with same question but seems like people misunderstood the question.
I am not talking about "lack" of memory, or not having another 32/64gb availble, etc.
I'll give you an example to what I am referring to:
Recently I decided that my rooted S2 needs a little 'refreshing', meaning - not just a wipe, but a complete format, to start from scratch. So I formatted everything, including /system and /emmc partitions. I then re-booted to recovery and had my rom file on the SD card so i was able to get a clean install.
Now, the question is - say I am at a stage when I need to 'refresh' the phone and wipe everything out. How do I then access the rom file for new install if I don't have external SD Card?
Thanks.
with adb.
What I do when I want a clean start, is I will load the rom/gapps/kernel to my phone, go to recovery, factory reset (with system if you choose), then flash all the things you want, then go back and wipe internal storage after. Then you're left with a fresh version of the ROM you want to install and no files whatsoever in the memory. Hope that helps.
I had the same suspicions a while ago. Basically with the nexus 5, even without an external sd, you can still do a full wipe of everything other than your storage. There is a path on the internal storage which essentially acts like an sd card, and when doing wipes in recovery it will not be wiped, unless of course you specifically choose to format /sdcard or all of /data. Read here for more info. I found that explanation very helpful.
So to answer your question, no, its not an issue.

I have the same issue, with my OCD, that I always need a complete wipe of EVERYTHING.
One option, I recommend if that's not an option at the time of flash, is to simply "reset" in settings. It clears out the whole SD, which is something I usually want to do when I want a FULL flash

Reset in settings just uses recovery unless something changed I haven't realised?
It should be down to what recovery you have (stock vs custom) as to whether a reset (regardless of how you initiate it) wipes /sdcard or not... or are you saying that's changed now?

Problem with factory reset, as far as I know, is that it does not wipe out everything. When I do factory reset in my S2, I still see old folders (even though empty) from before the wipe. That's why I like to format everything clean. When I mean clean, I don't want to see any old folder in there

Android Debug Bridge. It allows you to communicate with your phone via command line tools.
You would keep the rom somewhere on your internal storage (data/media) just like you would on any other phone. Then after wiping, you would simply choose to install zip from sdcard and your rom, along with any other flashable zip on your sdcard will be available to install. Basically when you do a typical full wipe from a custom recovery, the contents of your internal storage/sdcard are not wiped.

Lately, I've noticed that it wipes the Data as well. Unless It was only on CWM that it happened? I had installed CM11 with CWM and wanted to reset my SD. I used the reset feature and it erased everything, except the OS

I would flash the Rom first, then do the factory reset, the only downside is the nandroid you made may be lost, unless you uploaded it to GDrive or something.

3. Rooting
Now that your phone has an unlocked bootloader and a custom recovery installed you have a two options to gain root (Pick one or the other. You don't need to do both)
Option A) Flash SuperSU binaries which will give you root with the stock rom
Confirm that you have downloaded the SuperSU zip from the downloads section above and that it is located in the platform-tools folder inside of the android-sdk-windows folder on your desktop.
Turn the phone off then boot into the bootloader. (volume down + power). Once in the bootloader use the volume rockers to scroll onto Recovery Mode, then press power to select it. This should bring you into your newly installed custom recovery. Leave the phone at the home page of the custom recovery.
Open a command prompt window and run the following commands:
Code:
cd Desktop/android-sdk-windows/platform-tools
Code:
adb push UPDATE-SuperSU-v[COLOR="Red"]X[/COLOR].[COLOR="red"]XX[/COLOR].zip /sdcard/
This will copy the SuperSU zip onto your phone. Once the command has completed continue.
Instructions for TeamWin Recovery Project (TWRP):
Install > browse to SuperSU zip and select the it
Swipe to confirm the installation. Then reboot.

It shows how to "Push" a file to your phone. That is the best way, IMO. But instead of SuperSU, just "adb push ROM.zip /sdcard/"

Flashing the rom? Its honestly not any more complicated than flashing a rom for any other device. You download the rom to your internal storage. Boot into recovery. Then do a full wipe:
TWRP Full Wipe:
- Wipe
- Advanced wipe
- Select all, except internal storage
- Swipe to wipe
CWM Full Wipe:
- wipe data/factory reset
- wipe cache partition
- advanced > wipe dalvik cache
- mounts and storage > format /system
Finally you can then flash the rom (and gapps).

It's not really and if you're rooting and flashing any device, adb is essential knowledge.
Once you've installed adb (millions of guides on the net) you just boot into recovery then connect to pc via usb.
adb commands are run from cmd prompt.
For example...
adb push c:\users\sbi1\desktop\rom.zip /sdcard
Would push the file on your windows desktop called rom.zip to your sdcard.
You can even sideload from recovery.
Or better yet,.just don't wipe /sdcard. It has no benefit other than looking tidy anyway

While trying to do a factory reset (wanted to remove unuseful, old folders and start fresh with new ROM (p.s. now I know it was a wrong method)) accidentally checked all the partitions in WIPE section on TWRP. Thant included dalvik cache/cache/system/internal storage/data. Sadly it erased everything and now I am not able to put any zip to flash, since my pc doesn't recognise the phone. Now it is completely empty, only with custom recovery - TWRP. What should I do?
you must adb push or use USB OTG to get a ROM zip on your phone.

I would like to wipe internal storage to make better/clean install of the ROM (
with old S3 i make a folder on Ext SD with .zip file
reboot to cwm
backup
wipe all (cache + data + system + internal storage)
install (rom + gapps + kernel)
reboot
As you know on 1+ there is no Ext Sd
Someone has already tried to do:
copy .zip file to a folder on PC
reboot to TWRP (2.8.0.1)
make a backup
connect phone to pc and mount data
copy backup from 1+ to Pc
advanced wipe (cache + data + system + internal storage)
copy .zip file from PC to 1+
install (rom + gapps + kernel)
reboot
Can it work?
P.s. I have no OTG cable or USB
You should be able to wipe everything and install the Rom-Zip via ADB-Push.
Why dont you try to install the new rom in recovery with a normal wipe and after you falsh the rom + gapps do a wipe of the internal sdcard should have the same affect ?
are you out of your mind? DO NOT WIPE INTERNAL!!! WIPE SYSTEM AND DATA ONLY

Wow. Interesting thread. However, I wipe my internal storage (for a "full" wipe) everytime I flash a new rom or even the weekly of a same rom and luckily I haven't ran into the problems in your thread.
to the OP: I put all of my zip files in a USB otg so flashing is a bit simpler. This includes all of my nandroid and media.
I would wait to wipe the internal storage until you figure out which route you want to use (USB-otg or ADB)
Until then a normal factory reset in your recovery should be good. Also as @Hogyoku metioned you can erase internal from within the Rom to get the same effect.

That's not wise. You should never wipe internal plain and simple. All that s required for full wipe is system and data. If you continue doing so, you're going to find out the hard way one day

who ever is saying to wipe internal doesn't know what they're doing. This is the last I will mention of this here. There is no need and it's dangerous. That's how efs and the persist files get wiped and you find yourself in some serious trouble.
when installing a rom all that is needed is wipe data and system. Not cache, not dalvik and certainly not internal.
So many people have a misconception on how to properly wipe and everything seems to think they need to wipe caches on top of system and data. Well guess what, when you wipe system and data the caches get wiped too so it's just an extra unneeded step. And some people will post crap saying to wipe 3 times when flashing etc. They are simply making things up

This is complete bull****. Internal wipe will NEVER destroy anything it just wipes the whole /data/ instead of leaving /data/media. If you want your usb storage / internal sdcard / whatever you call it to be erased that's the one to choose. For a complete clean install:
1. BACKUP EVERYTHING YOU MIGHT EVER NEED AGAIN.
2. Grab ROM and GAPPS and put it on internal storage
3. Boot recovery and wipe DATA, SYSTEM, CACHE (dalvik is not needed because it's located on /data)
3. Flash ROM and GAPPS
4. Wipe internal storage
5. Stop talking about things you don't know correctly

That's really nice of you that you did that guide. But there is no way that bricks could have to do with that wipe. There is no way an internal wipe could corrupt any other partition than /data/ (efs, persist anything) beside of a bug in the recovery. Wiped internal several times on every phone and also the OPO with TWRP 2.8.0.1 and as you can see it's still running.

I downloaded lots of different widgets, wallpaper apps, themes, etc., to test different setups for my phone. I have the setup I want now, but the /SD card folder is cluttered with folders from apps and themes I don't want and don't plan on redownloading.
I have seen your warnings in other threads about wiping internal storage, so I haven't done that. On my Note 3, I had the external SD card, so it was easy to wipe internal storage and flash from the SD card. But since there is no SD card with this phone, I've been trying to read up on it. And there is a bunch of conflicting advice on what's safe and what's not.

You can store the ROM zip on your PC, then use TWRP to wipe your internal storage, then just connect your phone to your PC and copy the zip onto the phone to flash.

First of all do a factory reset(will clear all files ,folders and apps "excluding" system files) then transfer zip file(ROM) and gapps to your phone. Go to recovery > wipe> advance wipe > select everything except for internal memory and otg option > wipe > go to install > select the zip file(ROM) and flash> flash gapps > wipe dalvic cache > reboot

Hello, forum!
My current Pixel 2 is using the stock google system but I haven't updated the OS since March, partly because it's rooted
and the update process is not as easy.
Now that google said it'd only support the phone till this December, I'm thinking to install lineageOS.
However according to its installation guide:
...
3. Now tap Wipe.
4. Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
...
It's surprising that it need clear internal storage?
p.s. I may also think about installing Resurrection Rom. Does it require 'formatting data' then?
Afaik you must back up everything before installing new ROM, because when you install custom ROM you will wipe and format system and it will erase everything in your internal storage
If its rooted try modded version of twrp to backup your internal data as well

No, it's not, nobody wipes /data/media during rom replacement only /data.
However if his bootloader is locked, bootloader unlock will wipe everything, so before switching from stock a backup is must.
Alright, guys. Thanks for the input. Guess I'll just backup the internal storage and do as told.
