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.

Started with OMNI shown on galaxynote2root.com. Was working nearly flawlessly until today when I lost my mobile network (all services: phone, text, data - antenna was essentially gone). Not clear on exactly what I did when it occurred but I did flash 1/13/14 nightly manually via CWM (have done this with the previous nightly's without any problems). Tried wiping cache/data, Dalvik w/o luck. Tried formatting my internal SD also w/o luck. Doing a fresh install (as opposed to restore) did restore all mobile network services but of course I am now having to re-setup my phone. After installing fresh install, tried restoring w/o any wipe - again no luck.
Quite frustrating. I had read something out there that talked about remapping the tree (not sure what this means). In any case, is there a fix for this so I can restore my prior backups with mobile services working and also avoid this the future?
So here we go again; no service after wipe. Grrrrrrrr!!

So here we go again. Went to load the stock Sprint TouchWiz ROM. Wiped cache partition, wiped Dalvik, and did stand wipe cache/data. Had some issue with the stock ROM flashing so I went ahead and loaded my backup I just made of my newly setup OMNI ROM. And once again no network service what so ever. I really enjoy this ROM but it's thinks like this that push me back to the most supported ROM for my phone, the TouchWiz ROM. It's like I'm being held hostage to this Omni ROM in the sense that it appears that should I want do any wipe of any sorts or anything to that effect I'm essentially screwed and might as well just flash the the original ROM all over again.
There's got to be one of you Dev's out there that knows why this is happened and can let me know if there is a fix for this that will allow me to keep my setup as is. Someone who's knows, please response. If you need more info, please ask. I'm about to ditch this ROM over this issue. Otherwise, nearly flawless use of the ROM until this point.
Okay, so I was able to find a fix for this problem. After the complete wipe as described in my second post, I restored my recent backup. As mentioned above, no mobile service whatsoever at that pont. I then restarted back into CWM recovery and flashed the same version nightly as that of my backup and it appeared to do an update. I was then able to boot back into my restored backup with everything intact and all mobile services working.
Yes, I found a fix for myself but Devs why the heck do I have to go through that? Why cannot I not simply restore my backup and go on with life? Much headache over the past day or so over this.
So I installed the the 1/13/14 nightly as a fresh install. I stared messing around with advanced restore. When I restore only the /system folder that is when I lose all mobile cell services.

Sounds to me like you didn't wipe properly when flashing the ROM. You need to wipe system, data, cache, dalvik cache before flashing, is that what you did?
Usually when you update the same rom it's better to dirty flash no? i cant wipe all my data everytime i want to update the rom, though i might go back to stock, i
what's the best way to backup apps within the phone, and should i go deodex or Oden

My mistake, I didn't realise you were just updating the same ROM. Yes, usually you can just dirty flash, but the way something is implemented may have changed in the latest update, causing the issues you're having now. The solution is pretty simple though: backup your user apps with Titanium Backup, boot into TWRP and perform a full wipe (system, data, cache, dalvik cache), flash ROM + gapps, boot into ROM and set up your settings, restore your user apps with Titanium Backup.
Thanks a lot!
I had this same issue after the March security updates. Was given this and it fixed my issues completely! It manually runs the setup wizard. Not sure if it will fix it or not, but worth a shot.
