hello I have a question that may seem dum but through trial and error many times I realized asking the questions before actually doing stuff when it comes to android mods is best anyways I just flashed a rom code name Sammy to get a touch wiz experience and before I did that I did a nandroid backup through twrp recovery and I really want to go back to what I had before the rom or even try a different one like smooth rom but I wasn't sure if I could just restore from my back up or if I need to flash something differently all together to start over thanks for your help

Hi, johnfred1987...
No, there's nothing you have flash before you start over.
Prior to a Nandroid restore in TWRP, I prefer to wipe Dalvik Cache, Cache, Data and System - although be careful with wiping System; ensure you have either a flashable ROM .zip or a Nandroid backup on Internal Storage first.
If you wipe System without either one of these to fall back on, your Nexus 7 will have no bootable OS; just TWRP and the Bootloader. Although not an insurmountable situation, its a pain in the backside to recover from.
You only really need to wipe System if you're flashing a new ROM... although if you're upgrading a given ROM from, say, version v1.0 to v1.1, you can generally (unless otherwise specified by the developer), 'dirty flash' it over the top (although I still like to clear Dalvik and Cache).
Generally, though, all you need to do is 'Swipe to Factory Reset'... But whatever you do, don't touch the FORMAT DATA button, as this will wipe your Internal Storage, including any Nandroids, ROM .zip flashables, Titanium backups and whatever else you have stored on the Nexus.
Good luck.

To return to stock I was wondering if it was better to use odin or the One Click Recovery.
Do they both do the same thing?
Is one better than the other?
Thanks
Odin is only true way to go back to stock

I know odin completely wipes everything... if i just wanted to flash a new rom and kernel would that still be the way to go?

You need Recovery to change your Roms. Odin won't do that. If you looking to flash Roms, One Click by noobnl. If you wanna go back to Factory. Odin.
so then in all the threads when they say wipe everything they mean the clockwork recovery stuff. not a system wipe
Simple explination: When they say wipe, they mean inside of clockwork recovery you choose the option to wipe the cache, it would be like formatting a hard drive before you install a new windows os, u want to make sure all the old files and disk errors are gone. Same thing here, the cache is where the data/settings are stored.

awesome guys.. thanks for all your help
Not to be mean but no cache does not wipe your data. It's the equivalent to clearing cache on your browser. When a rom thread calls for a wipe they mean wipe data/factory reset, wipe cache, and go to advanced wipe dalvik cache.

I don't know about the whole format thing... guess you look at it that way. It only clears a part, and there's a few of those. But when you wipe your clearing all your data and setting. Each rom is built different. So in some cases you'll need to wipe to make sure nothing from the previous messes you up. The OP (thread starter) of the rom will say when to wipe. Should always wipe between roms. Cool thing is, you can advance restore your stuff back. ; ) or Titanium Backup. But something will alway catch you off guard or you'll forget. So have multi ways of backup. In clockwork you will see back up (Nand Backup as they call it), this backs everything up, if you mess up you can always go back like it was with restore. Have fun and don't let it piss you off.

With respect a454nova it should be clearer than that. If a rom says to wipe, the clockwork recovery probably should not be used to restore data because the ROM poster is probably putting something in data along with changing the system files. Titanium can be used judiciously to restore data files but only with full knowledge of what the OP has put in the data directory. Best practice is to use listables and download everything new then restore only items that could not be downloaded from the market
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!
I'm having a little trouble understanding nandroid vs. other forms of backup and would appreciate some clarification. I'm running CM nightly on my Fido (Canada) G4. I took a nandroid as well as titanium backup of the factory stock image before I flashed CM.
A poster in the last thread I made suggested if I wanted to restore to stock, I could simply restore the nandroid, but I've also seen people say you shouldn't use nandroid to go across ROMs. My understanding is that nandroid is like having a filesystem backup, which would obviously not react well if you restored it over a new operating system (e.g. two different versions of windows). Or is nandroid more like say Acronis, which takes an entire disk image and overwrites everything?
Other misc questions:
- If I do restore via nandroid, do I need to wipe all data / cache / system data before or after the restore?
- I assume I can use titanium to restore SMS + all non-system apps across ROMs, which would save a lot of time.
- If I'm going from one CM nightly to another, would titanium work for system apps (e.g. all my settings, or contacts, etc)
- If I want to flash a new CM nightly, do I need to follow the entire wipe procedure just as if it were going from one ROM to a completely different one?
Thanks!
always make a nandroid in recovery. i recommend keeping it on your micro sd card. in the event you need to return your device to it's previously functioning state, restore the nandroid in recovery. if you are running an aosp rom and your nandroid is touchwiz, wipe data, cache & dalvik before restoring the nandroid. if the backup is on your micro sd then feel free to wipe system as well.
if you want to flash a nightly or update to a rom you are currently running, simply wipe cache and dalvik then flash the update, gapps and any custom kernel that you may be running.
i cannot answer your titanium backup questions because i do not use that program

yes, that's about what I have. ok, thank you for the clarification of what to wipe! that's good to know.
re flashing a nightly/update: using your method should preserve system data yes? so no need to reinstall all apps or system data?
and thanks, I'll hold out hope that someone with titanium expertise will be able to answer that one

yes, system/user data will remain. understand, however, that if you perform one of these dirty flashes and you have a problem with the functionality of the ROM, you'll need to do a full wipe and flash to see if this clears the issue before you report the problem in the development thread.

Your right on both titanium questions.. However its not recommended to restore system apps you backed up on a aokp/aosp ROM to a touchwiz ROM and the other way around... Other than that like I said your fine

Hey guys!
I just got my GS3 rooted and installed the touch version of cwm and now am thinking of flashing a custom rom of my choice.
Now before I flashed anything I used the GS3 Toolkit to backup all my device and when I came to dig deeper on how to flash my GS3 I was left with one unanswered question that I couldn't find an answer to. My android version on my current device is 4.1.2 but the rom I want to flash (Dirty Unicorn) is based on 4.3.1. can I just flash it normally or are there a few steps involved to prevent my device from being bricked?
Thanks in advance I hope this helps someone out there as well
Lots of love,
A rookie passionate about Android!
No, I have flashed flashed DU a few times and even dirty flashed it over PA. You shouldn't have any trouble just make sure you follow the directions to the letter and make a backup first.
Good Luck.
Dnt forget to backup your EFS if you want to get back to 4.1.x or 4.2.x

Just a nandroid backup in the recovery on your external sd card, wipe data/factory reset, wipe cache, (and then i usually format system) for a clean install. Then go to install zip and choose your zip.
Don't forget to place your rom on your external sd card so you won't format it by mistake( I already did so, just be carefull and take your time):good:
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.
