I am currently on CM10.1 and have been considering testing other ROMs for the Nexus 4. All ROM flash guidelines ask that I wipe everything and do a factory reset before I flash the ROM.
My question is does doing a data wipe permanently erase all data on the phone? Including installed apps, app data (game saves, whatapp chat logs, etc), SMS and Contact information, gallery files, wifi passwords, etc. Or is it just some ROM specific data. More importantly, if it is more than just ROM data, is this data gone forever or is it synced with the google cloud and is simply synced over the internet once the phone is setup with the correct google account again? If it is synced, what data is synced? I presume at least contact information is synced with the cloud but what about the rest.
I could find any clear information on what exactly wiping data entailed and what could be the expected unrecoverable losses possible. Also can I just take a backup of the data using some app (Titanium backup?)/nandroid backup and restore the data once the new ROM is installed?
Factory reset will, just as the name states, bring it back to the state is was when you first got it.
So yes, every app and data of it will be lost. This includes contacts, wifi passwords etc.
Your contacts, wifi passwords etc will be synced to the google servers, if you chose to do that when you set up your phone for the first time.
However, it will not wipe your sd card, so all your photos and music will be save.
I'd suggest you make a backup of your WhatsApp history, this way when you re-install it you will be prompted if you want to restore the messages from the backup.
Hope this helped!
EDIT: It is not suggested to restore data from a titanium backup, since this can generate problems.

Is there any difference between delete cache and data and doing a factory reset?
While doing a cache wipe, only files from the Cache partition are being deleted. These files were saved by your phone to use as cache. (Think of it as your browser history. if you wipe that, only certain files will be deleted, while the app itself won't be touched)
While doing a factory reset everything will be wiped, including the cache partition. Excluding the sdcard ofcourse.

Ooh, old subject haha.
The android OS IS your rom, so to have a full stock android rom, like you had when you first turned on your nexus 4, you need to flash the factory image provided by Google. Link to factory images
If you dont know how to flash these files, efrant has a great guide on how to do this. Link to the guide
thanks for ur info

By wiping rom, did you mean to wipe system off your device? If that is what you meant there, then your device won't boot after that because there is no OS installed. To clear your confusion factory reset only set your device back to the default settings when you buy it. Means it will wipe your downloaded apps, cache, saved data, contacts, messages etc.. Some stock recovery doesn't wipe your internal sd card when you performed factory reset (means all your pics and music are still there) while in some other erases all and you will be left with nothing..just like how you first received the device from store.
Further down, if you flashed any custom rom on your device and you do a factory reset. It won't wipe away the custom rom that you installed, it will only set it back to the rom default settings. To get it back to the stock manufacturer rom, you must flash the official rom released by your device manufacturer. I hope this will clear your confusion.
thanks

I am bumping the post instead of openning a new one - because it is the same question.
You wrote that Factory reset will not wipe Photos, Music etc.
Did you mean that if I saved it on external SD? Because in Nexus 4 there is no option to add SD card.
My question:
1. In my nexus 4, when doing factory reset - it erases EVERYTHING include Photos and music. so please help me understand.... cause I am confused. Does it reset everything or not?
2. In nexus 4, where is the option to Wipe data? I see only "Factory reset". In recovery console?
3. Any differences between Factory reset from the settings, to wipe data from Recovery?
thanks!

1. We do not have external sd in nexus 4. There are 2 types of recoveries; stock and custom. Stock recovery is what you get when flashing factory images while custom recoveries are twrp/cwm. In stock recovery, factory reset delete everything on your device. Everything in your internal as well. It will wipe clean your device. For custom recovery, it won't clear your internal sd storage so your photos/music/docs/backups are intact. It will only delete data partition which stores your downloaded apps. I hope you are clear on that now.
2. Factory reset=wipe data. In every recovery, it's the same.
3. No, it uses the same command so basically there is no difference. Depends on the recovery you use, factory reset on stock recovery deletes everything while on custom recovery sd card is still intact.
The answer that explained everything for me - is that there is a different between wiping data from Stock recovery to wiping from Custom, so now i get what you mean!

Flash rom and keep apps and data
Hi. Is it possible not to factory reset/ wipe data when flashing a newer rom? The reason I am asking is because I want to flash Lollipop on my Note 3 as Samsung keeps forgetting to send it to me OTA or via Kies. But I don't want to lose all apps and data. Thanks in advance.

Hey. I have 1 question. I have pictures, music and videos on my Internal Memory, and I don't want to lose it (I didn't back it up anywhere and I don't have an SD card). Will Wipe Data/Factory Reset delete those stuff, or just apps, settings, etc?
I'm using S4 Mini i9192. I also have Philz Touch Recovery.

I have not used Clockwork recovery for a very long time now so I don't know how it works nowadays. But last I used it, factory reset in cwm (philz is a modified version of cwm) does not result in complete wipe. It will leave out the sd card partition. But like I said, it was very long time ago. Make a backup of them if it is really important. Well, in my opinion, everything needs backup. Even things in your computer needs a backup.
p/s: Try to ask this in S4 thread. Here, we (nexus 4 users) mostly use twrp as cwm is discontinued for quite some time now.

Okay, so this is a silly and weird question, I have recently rooted my phone, an S4 GT I9505, and due to certain circumstances (buying an S6 on a sudden whim cuz of a great offer) I want to unroot my S4, now, I wanted to back up my data so I am using the Samsung Smart Switch program on my PC, and it says there is an update for my phone, so I was wondering if I do that update, will it unroot my phone? Also are there any risks of losing my data in the process? Thanks for help in advance ^_^

1. You can backup your data only copying internal/external memory to your pc.
2. The best way for unroot your device is booting to your recovery, wipe data/factory reset your device (will delete all your internal data) and wipe cache partition. Boot in DOWNLOAD MODE and flash the new update directly via ODIN.

Can't I just use the unroot function in SuperSU? I have no intention of rerooting this phone.
The unroot function of SuperSU should work fine, rather than going through Odin. The next person who acquires your S4 will likely end up doing what I did and start from scratch anyway.
My phone has been very flaky and freezing all the time. Sometimes it just reboots itself. I want to do a complete wipe and restore. What exactly should I be looking to back up and how? Pretty much all my apps are on my sd card. Can I just remove it and put it back after the wipe to use the apps again? I know nothing about twrp or cyanogen. Are these options I should consider? I'm assuming I will have to re-root after. My current root is called kltetmo. Should I just stick with it? Seems to be good enough for the apps I use. I'm using 10% battery at least for every hour I'm using the phone. Mostly social apps and forums like this. I don't game or anything like that. Any help without sarcasm will be greatly appreciated.[emoji4]

Try using an app called Titanium Backup Then you backup your files to your SD Card.
After you install via ODIN the TEAMWIN PROJECT RECOVERY. After installing Teamwin project, you put the phone on recovery mode by pressing and holding Volume Up, Home and Power key. and do a full backup of the system.
if you are already rooted, then you can wipe via TWRP the new stock firmware - GALAXY S5 FIRMWARE.
u can bypass some of these for the backup by downloading kies 3 and using it, you can backup all yours apps some of settings even your lock screen settings, after you finish your cleaning part ( wipe .. ) u can restore what u've backed up using kies 3.. real simple step. then u won't be in-need of removing sd card then putting it back.. Good luck!
If your S5 was slow, installing all those apps again after a clean up will make it slower again. Just backup everything inside your sd card to your PC and perform a data wipe (or factory reset in stock recovery, which could delete everything inside your sd card) and reboot your device. It should still be rooted after the wipe.
The phone is the Galaxy S8 G950FD (exynos). Today I have tried to root it using TWRP, but I didnt make a backup of my files, so I have not wiped my data in TWRP. The phone would turn on normally but it show the message about verification failed and asked to do a factory reset, but I didnt. Then I have flashed the original ROM though odin, but only the AP (about 5,1GB). Now the phone boots up and everything is fine, but it is factory reseted. It only show 10GB of total space, so I think my data is stored in another partition. There is a way to recover this data?
If you did a factory reset already, I don't think you will be able to recover your files anymore.
However, you should check by using a Data recovery App.
