My basic question is can I repeatedly reflash the same ROM to my Epic without wiping data between flashes?
I flashed a ROM and then manually flashed a number of add-ons and optional installs from other ROMs. My phone is now in a state that I don't like. I thought I did a nandroid backup after the initial ROM flash, but I didn't. I'd like to just reflash the same ROM that I already have on my phone, hopefully just wiping cache + dalvik first. I'd rather not wipe data and go through all that again if I don't have to. Is this safe to do?
Yes its safe. Only reason they say to wipe is going from one rom to other rom u may get some probs.

Sorry for the silly question. I'm on the go and I don't have my laptop. I need to know how to do a full wipe. Either from terminal or recovery. I am using recovery version 3.0.0.2. But when I do the wipe, and flash a new rom, somehow the wifi settings along with wallpaper and some other things are saved and I don't want them to be. I want a complete wipe...
Btw. I did uncheck the box for backing up settings to Google servers and its still restoring things. Getting frustrating.

on the clockwork 3.0 just wipe data/factory reset and it should be fine. Keep in mind though that 3.0 is only for gingerbread based roms such as CM7 or cm7 nightlies and I think there is another gingerbread floating around.
If you want to revert back to STOCK, or a 2.2 rom you can use rom manager to flash the 2.5 recovery. Then wipe data/factory, dalvik, cache, to flash a new rom. To revert back to 3.0 for a gingerbread rom just fastboot flash the 3.0 recovery

Wiping via ClockworkROM doesn't do a full wipe. I've encounter what the OP is talking about. I can wipe the factory ROM then go to flash a Cyanogen ROM and my wall paper sticks and some of various settings stick. Yes a factory reset and a Cache Clean, and Dav Cache clean and it will still stick.
He is talking about 100% fresh clean phone like you bought it brand new.
that's exactly right... 100 % fresh clean cm7 is what i'm looking for... but i can't seem to get a full wipe... keeps restoring some settings
I was using twrp and kept getting into bootloops so here is advice from a few hours ago. I suggest using RA to wipe boot, system, cache, dalvik, and data before flashing from stock. It stopped the bootloops and now im on cm 7.0.3.1

Wiping system is something that is often overlooked. The factory reset options in the recoveries do NOT wipe system. You have to do it manually. System is where the ROM gets stored. Typically upgrading is safe (check with the ROM dev), but changing ROMs (esp Sense -> CM7 and back) should get a system wipe.
Some ROMs do this automatically, some don't.
Also, use what ever recovery you like the best. Amon_RA is tried and true. Mature and proven. CWM has a shady history and while it might be fine now, many people avoid it. TWRP is the baby. It's freshly born and not as full featured as Amon_RA just yet.
Enjoy.
Thanks for the info. I will be flashing my first ROM on my newly rooted Evo 4G tonight!
Use" calkulins format all " before flashing any new rom
You really don't need to use those format all programs, if you use Amon Ra. Just wipe everything except the SD Card, really, and that should be done before you flash any ROM (Although SOME people will disagree). Better to erase all doubt than to leave a chance that an improper wipe caused issues.

Before you flash crazy you should think about partitioning your SD card(with amon ra2.3)that way you have that out of the way incase you wanna try a kingdom Rom, its something I wish I would have done before I went any further with flashing, just make sure you back up your SD to your computer before hand. Have fun!
Disclaimer: I'm used to my old Evo 4G and use a triple wipe script built into my recovery (smelkus) whenever I flash a rom. It pretty much wipes everything.
For the Nexus 7, what needs to be wiped to flash a rom? I did a factory reset, wiped data, wiped cache, wiped system, wiped dalvik-cache, and then flashed a new rom, but I wasn't sure if all that was necessary. I'm using the latest TWRP recovery.
If I'm moving from one rom based on a jelly bean version to another based on the same version, am I ok?
Can I assume upgrading to a new version of the same rom that I don't have to wipe? (I know this one is rom specific, but in general.)
Can I leave data and will that retain my apps? Otherwise, I use Titanium Backup religiously on my Evo and now on my Nexus 7.
I searched within some of the rom instructions as well as the rooting guides, but didn't see anything specific as to what to wipe. Some threads seem to say just factory reset and maybe dalvik-cache.
Instructions with what to wipe usually come in the original post of each ROM. Usually the same ROM with different version only requires a cache wipe while moving between different ROM's requires a full wipe/reset + dalvik.
Worse comes to worse you try something and it doesn't boot and you get back into recovery and fix it.
Hello people. Just wanted to ask how is the right way to wipe when flashing a rom WITHOUT losing the rom (wiping internal)? In CWM i just factory / reset data then thats it then clear cache and dalvik cache. In TWRP do i just need to swipe when the screen says "Most of the time this is the time that you need" when i will flash rom? Thanks for guiding!
anyone?
1. factory reset
2. advance, wipe system
thats all for me, works everytime... just make sure to wipe cache/dalvik after flashing zip files be it roms or gapps or whatever :good:
The default "most of the time" option is a fresh reset of the phone. it wont wipe the ROM itself, but all the data will be lost and you start over. Wiping system will remove everything, a ROM must be flashed after wiping system.
So before i flash a rom i wipe the "most of the time" then advanced format system? right?

true that... sorry for misleading initially, format system only applicable if you wanna have clean install of new rom

No need to use format system unless you are installing a fresh ROM. Format system will remove everything from your device (other than sdcard info and all that). So you get a clean slate.
If you just want to flash an update to the same ROM you can either 'dirty flash', which I usually just wipe cahce/dalvik then flash the ROM and reboot, and you save all your user modified things, or you can wipe system and install the ROM. You lose everything that way so make backups.
Usually there isnt much need to factory reset unless you're having an issue with something. What is it you're trying to do?
I wanted to flash a stock based rom. Thank you.
Just as title states, I always spend a lot of time after restoring apps and data from flashing a new ROM getting my screen and layout and folders and widgets as they were prior to flashing a new ROM.
Is there a way to restore all this quickly?
NO
The problem you're having is when you install a different ROM you usually "Wipe" everything. If you don't wipe /data then everything you have is still there. However you will have problems going from one custom ROM to another, as each developer has made some tweaks to the system packages.
Generally speaking, if you are running a "Stock Odexed" ROM you could possibly dirty flash a "Custom Odexed" ROM.
Same goes for Deodexed to Deodexed. You will have problems if you try to cross dirty flash a ROM.
So the simple answer to your question is NO there is no easy way, even if you backed up your Applications using a tool like Titanium Back Up.
If you are just updating the same ROM, the developer will say to either Clean Flash (wipe everything) or Dirty Flash (IMO still wipe cache and dalvik). If you can dirty flash everything will still be just as you set it up.
Got everything restored already, I'll have to just suck it up then I guess.
Just makes me wonder how flashaholics do it.
