wipe data/cache question - Android Software/Hacking General [Developers Only]

I understand the basics of modding...i currently have an AT&T skyrocket running the SKY ICE Rom. I've ran a ROM backup via Rom Manager. My question is, if i want to try a new ROM then i would run a backup right before installing a new ROM. then go through the same process as when installing the first ROM (wiping data/cache) right? Wont this delete my backups? Or what exact data is it wiping when you do it? and is it safe to have an external SD card in the phone when doing the wipe? I dont want to lose any information on my sd card and its always worried me so i take it out. thanks for any help

When you install a new rom there is no need to back up again if you already have made a back up recently (if it is a old back up then make a new back up and if not required delete the older back up as they consume a lot of space). Regarding the loss of SD card data, you need not worry only the data on phones internal memory gets erased.the back up which you make on rom manager is safe as it is stored on your SD card.hence,there is no need to take out your SD card when installing a new rom.

so doing a rom backup doesn't backup all your current apps and settings? i hate losing my aCar info and my plants vs zombies saves. when i did my first nandroid backup (before i flashed my current ROM) i had my SD card out i believe. and when i did the wipe through CWM it didn't completely wipe the phone out. i believe all the folders where still located on the phone.
i just want to backup my phone to the way it is currently and try out some new ROMs to see if i like one better and be able to go back to this one if i decide i dont like the new ones. i know that i can back up all my apps and user data with titanium backup and reinstall apps and such to a new rom if i choose to stay with it.

thanks

this is a good explanation. I did a data/cache wipe, but was wondering what stayed, and what goes away. I just updated to Franco's kernel (I'm using 4.0.4 ICS) and tried to get back to the stock kernel. well. I failed.

Nearly stock rooted 2.3.3

Is there a ROM out there with root, clockwork, etc etc already installed that wont completely wipe my SD card? I am tired of loosing EVERYTHING on my SD card each time I have to do simple tasks on this phone.
I am on a rooted 2.3.1 and loving it but I would like to try out another rom. Most of the roms out there now are for 2.3.2 or 2.3.3 only but to upgrade and loose root means to have to wipe my sd card again to unlock my bootloader hence my question
As far as I am aware, when you unlock the bootloader or flash a new ROM, it shouldn't be wiping your SD card (/sdcard).. However, when you flash a new rom, its highly recommended to wipe the Data & Cache. Though doing this DOES wipe your settings etc..
Since you already have root, you could simply download Titanium backup to backup all your settings/apps/data (there are plenty of guides for this..), then flash the new ROM, and restore everything with Titanium Backup again. The process is very simple and doesn't take long at all..
Also, most ROMs that are in these threads should already be rooted and contain superuser, busybox, etc..
The closest to stock that I've seen is here. There are four flavors and two of them are already rooted..Though I think this ROM is no longer going to be updated.
The current ROM I use is NSCollab and I would highly recommend it..It already is rooted and contains tweaks and a few apps like ROM Manager etc..
Actually when you unlock the bootloader it does delete your SD card, yes that includes your titanium backup folder ie you loose that too.
Wiping settings etc is no big deal, but wiping all my music, photos, titanium backups etcetera etc is what I am concerned about. I lost all the when I rooted initially

TI can sync to a dropbox account. As for the Contents of the SD card. Back those up before changing ROM's. My understanding is that it's the bootloader unlock that wipes the works (I did mine the day i got it, so it was already virgin)
Most of the third party roms offer upgrade paths without wiping, CM7 for example, you can keep updating and rarely do you have to re-install a thing.
but once you unlock the bootloader, you should never again have to wipe your sd card. at that point, any time you change a ROM, the sd card remains in tact and is not wiped. so you only lose data the "first" time you root. then from that point forward, you change ROMs at will and lose nothing etc.
If you can't use dropbox, you could simply backup with titanium and copy the contents from the sdcard to your computer, then unlock the bootloader..

[Q] Best way to start from "scratch" before flashing a new rom?

I'm on an OG Droid and am currently using CM7 RC4. I'm very happy with this rom, but I have been having issue after issue, no matter what rom I'm using.
I'd like to start fresh, clear my SD card, clear all app data, etc. and then reinstall my apps manually. I'm hoping that this will remove the possibility of something being corrupted or lingering on the card and affecting the current rom. So, I'm looking for suggestions on the best way to do this.
Also, I'm wondering if anyone can tell me if they have been stable running GB on a Droid with CM7? I'm running LauncherPro, Lookout, Tasker and AlarmDroid, and they all seem to be fighting for memory and not able to work properly. Any suggestions would be greatly appreciated.
So far, I have:
Made Titanium backups
Made rom backups
Made a copy of my SD card
Erased SD card using the option under Settings...Storage
Copied the CM rom back to the SD card
Copied the clockworkmod directory back to the SD card
Also, I have a bunch of apps installed, and don't want them all reinstalled after I flash. Do I need to manually uninstall all of the apps I don't want upon boot, or is there an easier way to keep them from syncing?
I'm getting ready to flash the rom. I know I need to wipe data and wipe cache. What else?

1. A flash over the top with no wipe will keep your apps. If however the dev has done an update with a new base, a wipe is recommended.
2. Do a nandroid backup and try the kernel. I get fantastic battery life on coredroid with it.
3. Yes but NEVER rename the folder else it will never restore. It will fail on md5 checksum error.

If you wanna backup your apps, use Titanium Backup. It's awesome, use it all the time. It also backs up data.
Also, you need to manually wipe all data before you flash
Kernel is optional, but you should try it.
About the backup - put it in the PC, i have. If you ever wanna delete the backup from your phone but want to keep it on your PC, then delete the contents of the backup folder in the phone, not the folder itself. I have 2 backups on my phone right now. Consumes waaaaay too much space. Got 5 on my PC
OK..... So if I use titanium backup now for some apps and install another Tom it will be there even if I wipe data and stuff?

So with virtuous unity does it reproduce the same battery life as stock

no. You need to restore the apps.

[Q] Help coming from Windows Mobile to android

So i am very new to android, i did however figure out how to get root and get clockwork and flashed a custom rom. I have two questions. 1. I am currently running honeysense rom and see there is a 7.3 update, how do i go about installing the update? will doing the update erase all my apps i downloaded? If so i did back them up using titanium back up.... do i have to do wipe data, cache and all that in clockwork before installing the update?
2. If i want to do a completely new rom what are the steps to doing this as i have all this stuff on my sd card will post a pic of it curious as to what can all be deleted to free up space when starting fresh...
3. Last question sorry, i made a back up of "stock" rom before flashing the honeysense, and i named it "stock" where is that located??
ok so i thought i only had two questions changed to 4.
4. what is pd98img file the third to last one on the pic i uploaded, can it be deleted?
1. Check what Android version they both are if what you have now and the update are the same Android version (2.3.4 for example) then you should be able to just wipe the Dalvic cache when flashing from ROM manager. This will keep all of your apps and settings and flash the ROM. However it's VERY IMPORTANT to make a backup before trying this because certain settings may cause problems and you may need to restore your old version and do a clean install.
2. If you want to try a different ROM you should always wipe all data and caches before doing it, this can be done via ClockWorkMod or Rom Manager. But after that it's just the same as flashing the ones you have already.
3. I'm not really sure but I'm sure someone knows or you can find it via search.
4. PD98IMG is used when rooting to flash the downgraded rom automatically, it's safe to delete, and if you ever need it again it's easy to find.

I'm not sure what version it is, its on the download link for the rom's link I have a issue where my phone shuts off and gets stuck on the screen after the splash screen and stays there happens every two days or so and this update is suppose to fix it here is the link doesn't really say anything bout what version android it is
never mind i cant post links yet, but in honeysense forum section on here just uploaded a 7.3 suppose to fix my issue i dont think its a change in android version just a fix. If that is the case do i do apply update from sd or apply zip from sd?
2. If i do a full whipe doesn't that erase everything?? including my back ups of the roms i have backed up? never mind on that one found my answer, doesn't touch the sd card right?
Thank you for the quick response.
You can just apply the update from SD, you can even do it with ROM manager and it's a little more straight forward. I'd just take a swing at it and hope it works, if not you always have backups you can restore.
And no, all of your backups should be on your SD card, you dont need to wipe the SD card when flashing a new rom.

ok its 312 mb so im assuming do a full wipe and reflash correct? if this is case can i copy the clockwork mod file that contains my back ups to my computer and also titaniumbackup file to my cpu do a install the rom on my phone then do a format of my sd card? and have it be blank then copy and paste clockwork mod and titaniumbackup back to my sd card and be good to go?
I am sorry for being such a noob to android lol
a full wipe does not mean wipe the SD card. you can leave that untouched
I think you misunderstood me, you DONT need to wipe your sd card, wiping data/cache wont touch your sd card, and flashing wont do anything to it either, you should be able to leave all of those files on it.
i got what your saying i just wanted to start fresh i guess you could say...with a fresh sd card and this newer build i just downloaded the file and its 312 mb so i figured i would just start back from scratch, and wondering if i can do a full wipe on the phone put the rom on my sd card flash it, i have a back up of the older version in case something goes wrong on my sd card can i take the backups copy them to my computer along with the files in titanium, after the format is done with the sd card copy and paste them back on the sd card and restore titanium files and if need be restore the previous version of the rom? so then i have all most of my free space back on the sd again. Will this all work this way?
Ok, i get what youre saying now. Yeah, there's no reason that won't work. I transfered everything from my SD to my computer and then back to another SD because i got a 32GB one. You shouldn't have any problem with that.
ok thank you very much for helping me understand this a little bit more appreciate it a lot

A lot of crap on the device p3110

Well this may sound stupid but i masterd the root and flash method, i thought. But when i factory reset the tab, wipe cache and dalvik and all that there is still a lot of old crap on the device. There is however an option which says format sdcard, and there is the problem. I am kind of a chicken sh#t and do not dare to select that option, affraid of wiping everything and not be able to flash a new rom. Do i have to format sd begore flashing a new rom?

The crap will be there till you load another rom. Yiu can always remove some stuffs from system/app but i think you shouldnt. Hope some1 with more knowleege can confirm or correct me.

Depends on the stuff you want to delete, but wiping your SD card is not the right choice unless everything on your SD card is just junk.
Load a ROM that is more to your taste and/or use Titanium Backup to remove the bloatware that you want gone.
If you want to use stock ROM then root your device and use Titanium Backup to remove bloatware (back up the app then freeze it or delete it.) then reboot.
I tried that option when I had cm 10 on my tablet it deleted evething on my internal sd card but did not mess with my system ..after doing that I booted normally into cm 10 from cwm....:cyclops:
