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

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'm still pretty new to Android, I want to get into customizing my epic, specifically learning how to load custom roms.
I'm looking for some good how to resources, I've done some preliminary forum searches with some success.
So far I've updated to 2.2, and had the gps problem. Searched for a solution, found multiple threads for the fix, most involve using Oden, I've had zero success with getting oden to see my phone.
So I searched for alternative methods,
I finally fixed the gps problem, by doing one click root > made a clockwork back up > flashed back to DI18 > stepped outside, got gps lock > Flashed to the DK28 > Then Restored my clockwork back up. After that the gps has been super fast to lock, usually under 5 sec.
But I'm still chasing the dragon, I want the AOSP Lockscreen, I've tried clockwork installing different versions from the popular thread about the AOSP Lockscreen, to no success.
But now I get an occasional black out screen, the phone is still on, it if I leave it alone, the stock tw lockscreen comes back.
Now frustrated that I've come across another quirk, I want to try one of the 2.2 based roms, particularly the Nebula.
One problem, I can't find instructions on how to install it.
I do see instructions for other roms, I'm assuming that it's a similar procedure.
The Epic experience says oden to a stock 2.2, then in clockwork "wipe data/factory reset" before flashing the rom.
One question, when I do an oden flash to 2.2 and "wipe data/factory reset" will it delete my clockwork back up?
Current mission.
1. Have a backup of my data and apps.
2. Install a custom rom
3. Restore my data from backup.
Questions:
1. Anyway to use a custom rom with out Oden?
2. Is it completely necessary to do a factory reset?
3. Factory reset, will this effect my phone account information, such as being associated with my phone number and sprint account?
Any information is greatly appreciated!
Thanks in advance.
I'm a linux user, I've never used odin and I'm running the current rom of mammons.
When using clockworkmod to do the resets for factory and cache, it will not wipe anything stored on the sd card. So as long as your clockworkmod backup is on your sd card, and it should be, you won't lose it.
Factory reset and deleting cache its required. Do it 3 times to make sure its done before flashing the me rom.
It will not mess with your phone number our account info.
I recommend downloading titanium backup and backing up all app data and user system info.
If you have more questions that you couldn't find on the forums, our need clarification, ask away.
Sent from my shoe, I mean....Epic shoe... I mean Samsung Epic! http://mobilehighway.blogspot.com/
Thanks
Thanks mxcoldhit, I'm now running my 1st rom, Nebula, so far so good.
A few notes from my experience:
From my previous clockwork back up, restored that, installed titanium, backed up my most used apps & info, exported my contact info from the contacts app.
Went ahead and wiped 3 times, loaded my rom, installed titanium, restored all my apps and info that I've had since day one.
Things of note to noobs like me, clockwork is awesome, back ups seem to work like ghost images, whole frozen snapshots of the os with all data & apps.
Titanium and clockwork both store the backup data on your micro-sd card.
So you can play with different setups and if you want to go back, just restore the back up file, they don't get wiped when you wipe the phone.
Titanium works in much the same fashion, install it on your system and you can make back ups of apps and phone data, when you load a new rom, just go ahead and install Titanium if it's not already there, and you can restore your favorite apps and data.
One thing that confused me before realizing what i was doing wrong, was that after I flashed the custom rom, I restored my backup thinking that it would just add my data and apps back, well it does that and the os also, so just keep that in mind.
hi guys, would really appreciate your help..
i was trying to fix my nexus 4's problem of unable to sync with google servers so i deleted the data/data/com.android.providers.settings and it indeed fixed the issue.
unfortunatley, after rebooting, i'm now:
- unable to get a lockscreen
- unable to get home button to work
- swipe down settings are gone. and so are notifications
is there another way to restore this other than a factory reset?

He only deleted the data so of course a factory reset will fix it this.
You will probably take ages trying to fix and end up having to wipe anyway. I take it you haven't got a backup of any sort (nandroid/ti backup) etc?

Yup, my bad. So many users wiping the entire sdcard nowadays that i took it wrong and didn`t read correctly
I thought I did but I searched my PC and couldn't find any previously backed up data. So I guess I've no choice but to factory reset and reinstall my data

Hi there! I had had the same problem l33chpda had, but the factory reset fix worked just one time only, today i was about to resell my phone so i wanted to factory reset it, after that i've come across with the problem i had that time, again.
Don't know what to do, i have same issues mentioned by l33chpda, cant get into settings, swipe down settings neither, etc; when try to, phone just do nothing or stays one second and goes back home screen.
I have made nandroid (both clockworkmod and TWRP) of the phone when I bought it, but with online nandroid so i don't have any custom recovery installed.
While checking those nandroid backups, I've discovered the deleted folder backup in the clockworkmod nandroid folder.
Could it be possible to paste it back into "\data\data" folder? should that be the fix? Or I'll have to reflash all even though I dont wanna take that risk because is just that, the other things of the phone are intact and work great.
In case of reflashing, could you tell me about any easy tutorial on how to install clockworkmod recovery?
I own an LG G2 D800, KitKat d80020y rooted with stumproot.
Hi all, I changed the levels automatic brightness adjustments, then a call occurred and I aswered. When I closed the call, my defy+ rebooted immediately (no messages appeared) and then went in a bootloop: cyano glowing logo, then a single red LED flash, then it repeats.
Tried to clear dalvik cache, with no luck.
Is there a way to recover easily? Unfortunately I have no backups but want to keep contacts and application data. Not interested in keeping SMS's or photos.
Thank you
Contacts are usually stored with gmail account. I don't know about the app data though.

Make a backup of your /data in custom recovery, then wipe your /data partition (and cache/dalvik if you want), then reboot.
This will most likely get it to boot up again, then you can use Titanium Backup to restore your apps and app data. Do not restore your complete backup, because it most likely got corrupted, and do not restore System apps either.
You can restore SMS, by restoring Phone/Messaging Storage, and to restore Call Logs/Contacts, restore Contacts Storage. You might want to check the "Migrate System Data" checkbox in Preferences if it doesn't work at first.
Thank you, but I've already gone RSD. Good to know anyway. tnx

Sorry we couldn't find a solution in time.
For me, it's not that important; I full wipe at every sign of a bootloop. With the Desire I used to wipe all, including /system!
As long as you have a google account, you can reinstall the ROM and add your Google account at the beginning. That restores your previous setup of applications and appdata. Contacts are automatically synced and added to People.

First be sure to remove your external sdcard if you have one in the phone.
Then turn the phone on normally (no odin, no recovery and no reflash).
Then go into settings>accounts>backup and reset> then click on the very
last entry on the accounts screen which says: "Factory data reset".
Doing that will wipe EVERYTHING including email accounts/emails
phone numbers, user flashed or installed apps, games and so on.
It will also wipe any pictures, videos, documents, music files and mms.
After doing the above you can be assured that the phone is in stock
condition and has nothing personal in it.
Have a great day!

you will have the same with the method above.
not 100% if stock recovery has this, but besides the factory reset you have to format the internal data. It works from custom recoveries for sure.
as an alternative, you can manually delete all the folders in internal card and do the factory reset again.
of course, the external card you either remove or format aswell (from phone menu or recovery).
So I was with my journey to free some space, Suddenly I saw data_1, data_2 and data_3, So I removed them.... And now when i restarted my device.. mostly everything removed but gallery! What do I must do to restore my phone? The factory reset solution will be the last solution if nothing worked
Factory reset will not install deleted apps. Factory reset will delete every user-installed apps.
Reinstall rom. That's what I suggest. If you don't have any backup of your current rom.

It showed me after reinstallation" UID error " and that I need to wipe my data partition in order to use your device as stable. After I clicked (I'm Feeling Lucky) It took me to the launcher with the same things, nothing has been changed.. Other suggestions? Or do I have to wipe and relax?
What are you talking about? What exactly did you do?
I reinstalled the firmware, Nothing else.
I've taken my decision to wipe data..
What rom are you actually using?
Stock.
Thank you for helping as I fixed the problem by wiping data, my whatsapp, gallery, and music all restored!
