Question about erasing data/reformatting in CWM - Nexus 7 Q&A, Help & Troubleshooting

Do any of the options erase /sdcard? I would like to know before flashing a ROM.
Sent from my Nexus 7 using XDA Premium App

On TWRP, there are 4-5 different wipe options I believe. If I recall right, 3 of the options are cache, data/factory, and dalvik. One setting is to also format data, and the other one is to wipe SD card.
Wiping cache, factory/data, and dalvik doesn't touch SD card. Formatting data didn't work the one time I tried it, but it didn't wipe SD card either. I didn't touch the SD wipe button, but my guess is... it wipes SD
With CWM recovery, I was able to format and wipe everything (except SD) and the contents of my SD card still existed.

Much appreciated, I signed up here a while ago but never had an android device until November 2011. I have had extremely bad luck with partitions (some of which were really just user-error), so I am extremely cautious when dealing with them. Thanks!

Davlik wipe with apps2sd

So if you have apps2sd enabled with the phone writing the davlik-cache to the sd card and you wipe davlik-cache in amons recover does it wipe the cache on the card or phone?
I'm pretty sure it just wipes the dalvik on the phone. I may be wrong....

wiping data?

i wanna download some cool roms and it ask me to wipe data, cache and dalvick. when i do this.... will it erase all of my music, vids, and pics off my sd card? i have the phone plugged in boot mode... all i have to do is cleck yes to wipe data. i hope this doesnt make me lose everything
I'm no expert but have flashed a few roms. You shouldn't lose what's on your SD. I wipe cache and dalvik all the time even when not flashing a ROM. I've never lost anything. You would if you were partitioning your SD.
Hope it helps, good luck and have fun.

No when you wipe dalvick cache and cache you won't lose anything on your SD card just make sure you fully understand how to flash a rom first time I did it I messed my phone up do a lot of research first lol and good luck

Before you start wiping and what not make sure to do a backup. Also use Titanium Backup to back all your apps you downloaded the paid ones's or all the ones you downloaded. For contacts make sure to export them to your sdcard just in case. what recovery do you have? Should use Amon RA the best one for the EVO
Now when you're installing a new rom This for the Amon ra recovery but its almost the same for clockworkmod.
Wipe all user data/system
Wipe cache
wipe Dalvik cache
Wipe android secure (optional)
Wipe system
Wipe data
Wipe boot
Wipe rotate settings
BUT DO NOT WIPE SDCARD goodluck with your new root
Have a question here that's semi-related. I have been playing around with some different ROM's here the past few days. I noticed some of them are utilizing my SD card. When I do my usual wipe, it's leaving a few Widgets, etc in place. I know it's the SD card, because when I repartition the SD card, I finally got rid of everything that wouldn't wipe. What wipe/clear was I missing here, or is the only way to clear these apps/widges from the previous ROM is to do a SD card repartition each time?
Edit :
Just to be clear on the wipes/clears I've been doing :
wipe data/factory reset (Doesn't this cover most everything?)
wipe cache
wipe Dalvik cache
I also tried Clear Storage from hboot, but that didn't seem to help either...

Wipe in this order and I can assure things will work for you
Factory wipe(data-cache),wipe dalvik, wipe boot, and wipe system

...So, what ROM are we developing here? ...I'm not good at flaming...
@MPH33, you want to make sure and post questions in the Q&A section in the future.
My two cents here, is:
I always wipe my sdcard as well as what the others have said. I know you don't want to "lose" all your stuff on there, but really all you have to do is create a folder on your computer with the important stuff, like pics, music, backups. I use recovery to partition the sdcard, much faster than formatting on the PC.
The phone creates other temp folders on the sdcard that I am not sure what impact they will have on another ROM but I like to get rid of them.

the fact that you say you get rid of the left over bits when you repartition tells me that it's an apps2sd issue. Some roms use the sd-ext and some don't. In both CWM and Amon-ra you will find options to wipe the sd-ext. Add that into what you're already wiping and you shouldn't be troubled with leftover bits anymore. (and just to be sure, also add in .android-secure to the list of what gets wiped)
Wiping data/factory reset will wipe android secure and sd extension. So id just do what jaredthegreat said and run vr_superwipe script also.
It works same way as when your done using the toilet.

Flashing on N4

Ok, maybe this is n00bish but Ive never had a nexus device.
On my gs1, tf700 and such everything is flashed from the microsd card. If this device doesnt have one, how do you flash without loosing data?
Ive always learned, 1 wipe data, cache etc. 2. Flash rom/kernel (sometimes 3 wipe again)
Wont this clear your phones storage? This is a HUGE selling factor for me.
Im due for a upgrade outa pocket and I cant decide from GS3, Nexus 4, Note 2 or holding out for rumored gs4
Thanks guys

Clear Data does not wipe internal storage, just apps+data. If you were doing that, first back up using Titanium Backup, flash new ROM, restore from TiBU, PROFIT!!!
For backing up text messages, theres an app, though I can't remember the name.
Isnt there also an option that wipes everything? Factory reset or whatever. It cleans the rom and all I thought. Thats how we avoid bugs from rom hopping? Like I said Im n00b in nexusville but vanilla jellybeans sound delicious

There's separate partitions on the phone. Part for the system, part for your data, and then basically an internal SD Card. You would wipe the same way you would on any other phone: Wipe data/factory reset, format boot, system, cache, data, dalvik cache, etc, then flash your ROM. Your "internal" SD card will be untouched.
At least that's how I assume it would work...

Yup thats how it works. 'SD Card' partition is untouched during a wipe (though the bootloader unlock command will wipe absolutely everything, you just use that once when you first get the phone and its all good).

You are correct. But factory reset/ clear data even though wipes the phone clean, the 'internal SD card partition' isn't wiped. Meaning you would still have your pictures, videos and such. And also backup files. So once you do that and boot into the new rom, install TiBU from the market and restore your backup.
For a complete and 'true' wipe, as someone already mentioned, you could use ODIN/ Toolkit. Someone correct me if I am wrong.
Using TWRP. You can wipe: cache, dalvik, factory reset, system. You can wipe all of those and your internal store will not be wiped. Now with TWRP you can also wipe internal and external storage, do that and you will be SOL.

[Q] how to flash roms without losing data n files?

Alright guys I feel very nooby asking this but this is my first device that doesn't have a sd slot. Is there a way to flash a Rom without deleting the download and titanium folders?
My steps prior to flashing are
Wipe data, cache, n dalvik
Flash Rom
Then wipe cache n dalvik again
But if I wipe data then the Rom zip would be deleted before I can flash it?
Please help me on this thanks!

Hi,
Make only wipe data/factory reset, wipe cache partition and wipe dalvik cache, tat's all then flash your rom and reboot.
Don't wipe anything related to sd card/ext sd card or internal storage so you keep all your files in your "sd card" intact.

This won't happen on your LG G2. Even when using CWM you can see it is looking for an external SD card in the command line when doing a Factory Reset. You're internal SD card is never touched.
When you flash a ROM just:
Factory Reset
Flash Rom
Obviously make a backup first if you're worried, and you may need to flash Gapps depending on the ROM you flash.
understood, thanks guys

safestrap format internal sd

i tried to format internal sd card and it wouldnt let me. im guess its not possible?
Unfortunately, we can't use the FORMAT function in safestrap!!!....to clean wipe you can...go into Wipe then do Factory Data reset and then go to Advanced Wipe and wipe System/data/cache/dalvik cache...thats enough!!!
But if you want to completely wipe the phone...follow this thread: http://forum.xda-developers.com/showthread.php?t=2610757
