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.

I recently did the root from: http://forum.xda-developers.com/showthread.php?t=2291827
and the hot spot mod from: http://forum.xda-developers.com/showthread.php?t=2256950
I've reverted the hotspot mod and still the same result.
All my old apps work fine, nothing new that I download can be opened.
try clearing the data/cache on the apps then force close them and try to relaunch.....i had that issue with slim for a bit but it seems that whatever changes in build 6 were implimented fixed the issues.

stock rom.
Just tried a factory reset and now everything is crashing before I can even get into the setup process.
all services/apps that try to load crash.
I'm also unable to wipe cache from stock recovery, it says error.
is there a way to do it from odin? I'm waiting on stock firmware download, hoping that will make my phone useable again.
would installing TWRP and flashing an aftermarket rom potentially fix it? stock firmware is taking forever to download.
Stock firmware fixed the issue, scared to reroot the phone now tho....
if your having issues booting after a wipe try moving to to differant rom. if you like the TW UI there are still plenty of options for you in the way of custom roms. also if your going to be formatting your phone (i.e. wiping cache and dalvik and system components) i would recommend you load a custom recovery. you dont have to have one but it is advised.
Hi all,
I think I might have a problem, after I flashed xposed framework on my nexus 6p and got the modules that I wanted up and running no problem, during 4 or 5 days all worked fine but had constant reboots,
I decided to go back before I flashed xposed with twrp and restored a full backup, it failed to restore all selected at the same time, so did one a time and restored but phone would just not boot, so
Having data partition restored and then dirty flash stock without wipe data I was able to get my phone back and running, and re-root fine and flashed twrp no problems
Went to twrp to wipe cashe and dalvik but it just takes like 2 seconds optimizing apps and boots to desktop right up, now my question is
Shouldn't it take a very long time to optimize all my apps after the wipe????
all seems to be working fine but kind of bothers me that I might have something in not working right that might develop into something worst in the future
It is at this point I usually full-wipe and reflash. =) Setting things up again can suck, but it's better than wondering what unknown thing is broken and will rear it's ugly head later.

full wipe and reflash, want to avoid that, any other commands perhaps?
OK so I did a full re flash, back to stock, re root, installed my apps, used for a while, log in on all, went to twrp to test wipe cache and dalvik, same thing, optimizing apps at first boot took like one second and boot to desktop, is this normal or should take longer to optimize all apps?? Anyone??
is my understanding that only apps that havent already been optimized will upon boot... (new installs from like a zip)

thats what i am thinking too now that you mention it, like when I installed xposed initially and did whipe cache/dalvik thing after it took long time to boot because was on something like optimizing app 3 out 78, same thing I have seen on my old nexus 5 when dirty flash a new firmware, but not sure if I have something broken or is normal
