Installing new ROM factory reset - Nexus 7 General

Hi guys! I'm planning on installing a new ROM which I think would require wiping cache and restoring to factory settings. My question is would it also erase the data on my nexus 7 like videos, songs, Android day files for games etc?
Sorry stupid question but I was used to my phone which has external sd which makes sure all those files are kept even after doing factory reset.
Thanks you!

I'm not sure how CWM handles such things, but in TWRP, there is an option to FORMAT DATA... which wipes everything on the emulated SD Card... including the ROM .zip you're about to flash!.
So if you avoid that option and just SWIPE TO FACTORY RESET you should be okay.
Still, having said that, it's better to be safe than sorry... so I would recommend performing a Nandroid backup first - and Titanium backups of your most important apps.

It's always good to have backups anyways. If you have any files on your Nexus just transfer them to your computer (or cloud storage).

Okay I'm also on TWRP, meaning to say if I got to recovery and then straight to swipe to factory reset, my nexus will be on factory state but with all the movies, songs, android data still on storage?

Yep... that's pretty much it.
This, from a TWRP message output whilst performing a FACTORY RESET...
...wiping data without wiping /data/media...
If that weren't the case, and if it deleted all your user content, your Nandroid backups and the ROM .zip you intend to flash would be gone as well. So all that stuff (pics, videos, music etc.) is preserved.
Your user installed apps (from Playstore) will be lost though... so make a backup of them with Titanium.

[Q] Will I be able to back up saved games before flashing a ROM or wiping my device?

Subject says it all. I'm looking at flashing Cognition but I'm hesitant if I will lose all saved games. I have titanium backup but have only used it to removed at&t bloatware. Can I use that to backup saves? And if so.. how?
Sent from my SAMSUNG-SGH-I897 using XDA App
I use titanium backup and it has always restored my Angry Birds' saved games... I was three star-ing everything so I wasn't about to flash and lose it all either HAHA. I say use TiBu and you should be fine, though there are anomalies and I am not responsible for any lost saved games haha
Is there a "how-to" for titanium backup?
Sent from my SAMSUNG-SGH-I897 using XDA App
TiBu -> Menu -> Batch -> Backup all user apps
Flash ODIN
Flash new rom (you can click wipe data, it doesnt delete your sd card stuff, in fact, i recommend it)
Install TiBu (if your rom doesn't have it included)
TiBu -> Menu -> Batch -> Restore all apps with data
Click install, install, install. Done.
If you're really anal (which i was for a while), put in an external sd card and copy the titaniumbackup folder from your root folder to the external sd card and then take it out. lol
Ah sweet. So if I'm understanding those steps... the internal sd card is not treated like internal ROM storage that is wiped when you flash your phone?
Sent from my SAMSUNG-SGH-I897 using XDA App
No, but if you did, for instance, an Odin 3 one click back to stock, and clicked the master clear button, or if you do a factory reset, etc., that would wipe the internal SD card. So, if your ocd like me, connect to your pc and mount the SD card, and transfer everything on it to the PC hard disk. Then repeat that whenever you're going to flash. Just in case, you know.
Backup all user apps or backup all user apps + system data?

Do all backup stuff. You can later select what to restore. You can go in and just restore browser favorites if you want.

How do I flash ROM and Kernel flashed on a fresh partition?

I'm using Slim ICS 3.2 but I want a clean install, I've gone through so many Roms so I don't want any other file conflicts.

Alternatively transfer essentials to computer from your internal sd card>>>factory reset and wipe internal sd card>>>Attach to computer and only transfer back your nandroid backup (you still need this incase something goes wrong) and the rom zip...
Go to recovery wipe data/factory reset>>>wipe cache>>>wipe dalvik>>>mounts and storage>>>format system+cache+datadata+data (I dont wipe boot and you need sdcard)>>>Flash rom
That should give you a very clean install
Cleaner if you clear up your exsd if you have one

First dl. Your rom to sd (don't move it from your download section, this is your internal SD)
Just follow the steps, 3 posts up,but as he said DO NOT WIPE SD-CARD, doesn't matter if u wipe boot nothing bad will happen.remember to also wipe dalvik cache.
After wipe, install your rom and essentials(needed on slim rom) then let it boot.if u restore apps with titanium b. Then only restore app, not app+data otherwise u might have some apps fc
Hope it helped

You have deleted all your pictures music etc on your SD card. Including the rom that you were meant to or have already flashed. Also you may have deleted your backups and possibly your nandroid.
If you haven't flashed flashed yet ensure you make a nandroid backup and transfer the rom you wish to flash onto your sd card.

Enormous NAND backup sizes

So since sdcard is now part of /data, when I make a NAND backup the size is almost 4GB, since I have a bunch of music stored locally from Google Music. Is there anyway to get TWRP to ignore the sdcard directory when backing up (since it doesn't get wiped anyway) so that each backup I make isn't ginormous? I'm already down to only 15GB left on this phone. I know I could have it just not backup the data partition, but then restoring from a backup would only restore the OS and not the apps and configuration I previously had (which is kinda the whole point of a backup, since otherwise I could just fresh install a new ROM).
cant you just copy them over to your computer? and keep one on the phone for safety?
Just created a nandroid backup with CWM touch, mine came out as 2.1GB, not sure why your backup is so large
Sent from my HTC One using xda app-developers app
Mine are usually around 1.5GB. But I don't keep music and videos on mine.
Sent from my HTC One using xda app-developers app
Since the /sdcard data is sharing with the same partition as the /data doing a nandroid backup would depend on how much space is consumed by your sdcard.
So I guess nothing I can do, then? Thanks anyway.
Does this mean a Nandroid backup of the One would backup photos and media too?

Yes!
Problem is that Google Music cache is in /data/data folder, so Twrp backs it up. Solution is to create a folder on /sdcard and symlink the Google Music cache folder to it. Twrp won't back it up because it doesn't follow symlinks nor does it backup /sdcard. There are several posts on the subject, just search.

I don't believe it does, I don't think Nandroid would perform backup functions differently on different devices but coming from the SGN I - I can tell you that all Nandroid backups are basically settings and OS files as well as Apps / App Data. For the most part, when you do a Wipe / Format on your phone, it is only removing the OS files and installed Apps. It does not backup your photos / videos as it never really removes that data to begin with and so you should see your stuff there even after installing a fresh copy of the ROM. If you go into advanced functions in CWM and format your card, then you will wipe the entire device off.
IIRC CWM started taking nandroid backups very differently from a few versions ago, there's now a "blobs" folder in the backup folder and that is the one that grows exponentially in size. I believe that was done to only make incremental backups easy but the downsize is grows massive.
I cannot give you a guaranteed answer if deleting the blobs folder is safe or not but I have deleted it in the past and eventually resorted to just keeping the most recent backup by deleting all backups / blobs and then doing a fresh backup.
click compression and mines 1 gig
A nandroid backup also backs up the data directories and your downloaded Goggle Music songs are in that data directory. Therefore whenever your do a nandroid backup, the songs will be backed up as well, increasing your final size...

The recovery may very well perform nandroids differently on "data/media" services such as the htc one. Check out http://teamw.in/DataMedia

is there an app that lets you browse nandroid contents so you can confirm what has been backed up?

Ok just to answer my own question.
I just took a nandroid backup of One of my phones and restored it to my other one.
Music and Gallary did not come across.
If anyone else wants me to verify anything I'm more than happy to as I have both phones in front of me and all my settings and profiles are there, just no media.

[Q] How much used Storage in 'other' on HTC one

Hi
I'm very new to Android. I just flashed ARHD 4.3 to my rooted HTC one. Before that it was on rooted stock 4.1.2. Now, when I look at the 'other' section in storage in my settings info I have over 7gb of data in there.
Before I flashed ARHD, I wiped cache, dalvik cache, performed factory wipe, formatted data, system and cache. I was pretty thorough.(I even formatted my sd/data and lost root so I had to to adb Sideload superSU and adb sideload my ROM from my pc - not sure if I needed to sideload superSU but it seemed the right thing to do but yes, I'm still learning!)
Anyway, my question is how much data should be in Storage, Other on a 32GB Htc one? 7gb seems too much. Have I not wiped something? Is there possibly an issue with flashing that ROM. I don't seem to be able to post in that forum as I'm noob, so I'm asking here.
Thanks in advance...

This is my situation now.. I have the 32gb model and im using AndroidRev 20.2. i JUST flashed from 20.1 yesterday and did a wipe of dalvik, and a regular wipe, i didnt do the extra steps you did but now i have 15gb in other being used. it SHOULD be around 6 or less because i have a couple apks and Roms(PSP,NDS,PS1) not "ROMS" being held in my phone. I was going to back up all system data and user apps with titanium back up data but now its saying "insuffiecient free storage". I have 11 gb of storage left. Should I just copy all files to my computer from the SD? I also would like to know how to wipe away as much data and storage as possible without removing ADR 20.2

7GB of reserved space sounds about right. I also have only 25.49GB of free storage after a full format.

Change the TiBu backup folder in preferences
MENU -> Preferences -> Backup folder location -> Detect! -> Whole Device
It should find one in "/storage/emulated/legacy/<backup folder>", select that one. That should fix the insufficient space bug.

What was the result of "detect", didn't it give you two locations for the backups
In either case, you won't need to re-unlock or re-root, worst case you format your sd-card (ie internal storage) using recovery. Don't forget to backup your pictures, music, etc to your PC first.

[Q] Question about also wiping internal before flashing a rom

Hello,
I did a bit of searching and could not find an answer if it is safe to also include wiping internal when doing the advanced wipe before I flash a ROM (in my case a TW Rom to the same but updated version of a TW Rom). Since ROMs i've had interest in instructs only to wipe Data Cache Dalvik System x 3. Just wanted to make sure and perhaps find an answer as to why you would not want to do this. I apologize if there is a thread or answer for this already. Thank your time and expertise.

That stuff is stored under the phone data I would assume. This is the internal "SD card" you can store personal stuff and 3rd party apps on.
Should be no harm in wiping it other than it is 100% not needed and just erases your non phone data for no reason.
Sent from my SM-N910T using XDA Free mobile app
Caution. Many people are reporting problems writing downloaded files after wiping internal. That requires the extra step of fixing permissions in TWRP. Wiping internal memory is typically unneeded.
