Can I factory reset when my phone is done loading?
I like having a clean internal storage (there's some leftover folders from before). Will doing a factory reset break the rom or kernel? (Backup & Restore Factory Reset option in settings, not TWRP or anything else)
Should work. Worse comes to worse, wipe in TWRP again and format data and copy ROM/GAPPS/Kernel back from computer and re-install. That's how I do it when I'm feeling froggy.
Or just wipe everything and use ADB sideload, this will not use internal storage when flashing.

You can format data but will lose kernel scripts. Just download and flash kernel again after formatting data.

When I want to install a new ROM I usually do system wipe, factory reset, dalvik cache and cache..
I've noticed that there are others 3 options which one of them gave me a brick.
Format Data (gave me a semi brick since I could only access recovery mode but the rom to install had been wiped and couldnt transfer files to my nexus 7 through adb push)
External Storage wipe (since the nexus 7 hasn't got an sd card this option is dangerous?)
Internal Storage (even more dangerous?)
When I flash some folders are still there after doing the process described in the first line of this thread..
I would like to know if I can safely include the External Storage wipe or Internal storage wipe, and IF I do one of these 2 will I loose the .zip I have in my nexus 7 ready to flash?
Should I include one of these 2 options before flashing a new rom? (Since Format Data I know it wipes everything and only lets you access recovery, and you can't install anything since your .zip has been wiped aswell)
Thank you
Your already doing it right. The N7 only has internal storage. No need for anything else. I do have a superwipe flashable zip that erases everything except storage and repartitions the device. Not needed in almost any case except for bug fixes/tests.

All of these wipes are unnecessary. A factory reset is the only one needed, and it covers /data and /cache. Plus most installations will wipe the dalvik for you.

I have flashed many a Rom in my day, but the Nexus 7 is a unique beast. How do you flash a ROM and how do you go about erasing the internal storage without losing all the data on the device. I.e. what you are flashing the TWP back ups and the Titanium back ups.
IF THIS HAD BEEN POSTED BEFORE I AM SORRY I AM ON MY NEXUS I DON'T HAVE A WAY TO SEE OLD POSTS.

Unlock the bootloader. (THIS WILL ERASE EVERYTHING - PERFORMS A FACTORY RESET).
(So perform a backup first using either adb pull or Carbon (available on PlayStore)).
Fastboot flash a custom recovery, (CWM or TWRP).
Reboot into that recovery...
Flash the ROM of your choice.

No no I already did that. Like on my S3 I need to wipe cache/delvik factory reset. Doing the factory reset erases the internal storage, since that is where the ROM is being flashed from and where the twp back ups are those could get erased. Which can brick a device. So what do I do to flash a ROM cleanly. Every time I flash a ROM it bootloops.

factory reset on the nexus devices, DO NOT WIPE /data/media which is where your 'sdcard' data is.....

I'm a little vague about what you're asking here...
Haven't used CWM for a while (I forget the details), but in TWRP, having pressed WIPE...
...you can then select (In the wipe menu) CACHE, DALVIK CACHE, FACTORY RESET all with relative impunity... even SYSTEM ('Wipe System? This will wipe your ROM') can be wiped, if you have NANDROID BACKUPS or flashable ROMs to fall back on in internal storage.
The options to wipe EXTERNAL STORAGE, INTERNAL STORAGE and FORMAT DATA, however should be treated with EXTREME CAUTION... as you may be left only with a custom recovery (if you have wiped SYSTEM beforehand)... and then you'll have either have to adb push a NANDROID (or flashable ROM) from your computer or fastboot flash back to stock.
(As an aside by the way, you aren't really 'bricked'... you just have no usable ROM on your system; but that really isn't a problem if you know how to use adb or fastboot).

FACTORY RESET in TWRP doesn't wipe the internal storage... if that is what you're alluding to...
Rgrds,

That is exactly what I was wonder thank you for both your answers
So the Nexus 5 was released so it is time to hand over my nexus 4 to my little brother.
I'm running CM 10.1.3 with franco kernel, and I was wondering is there a difference between going into Settings -> Back & reset -> Factory data reset and going into CWM recovery and wiping data there?
I've done the CWM wipe but what I want this time around is to wipe all my files (music, photos, videos etc.) but keep the ROM as CM.
So how should I approach this wiping process? Thanks!
No, but if you want to wipe userdata (music/photos/etc) you need to select to wipe /data/media as well (this is located in the 'mount' menu of CWM.
Why don't you do him a favor and update it to 4.4 first.
Well I guess I'll revert to stock and wait for the 4.4 ota update. Seems like that would be the better route right?

settings/backup and reset/ factory reset data. will erase all data on phone, then you can do what you like with OS afterwards, you could format sdcard partition in CWM
I'm currently using Purity Rom and I want to erase internal storage.If I do a factory reset/full wipe from recovery mode, nothing happens.All my appz and files are still there.How do I do that?
Update your recovery and wipe again. Also there is a option in your settings if you just want to wipe your data
A custom recovery purposely does not wipe the sd card. If you want to wipe that, in twrp, go to wipe, advanced, and wipe the internal sdcard. Cwm has something along those lines too.

I had been using Cloudy G3 2.0 rom and when i had to sell my phone i did a factory reset but when i checked my file manager my files were still there so i had to manually delete them. Why is this the case? Every other phone or rom i have used factory reset wipes the internal storage clean leaving it new out of the box. I never understood this.why is this the case? All apps were uninstalled but some files or all were left intact. How can this be?
The default "Wipe data" option in TWRP excludes the internal storage (since phones with internal storage are likely storing the exact files they are trying to install in there) in order to keep the user from accidentally wiping the zip files that they are wiping data for. Boot it into TWRP and then do an advanced wipe for data and internal storage and you should be fine.
I had used factory reset option within the Android settings menu not the TWRP recovery, i never reset from TWRP always from the android OS settings.
