Hello,
I flashed CWM and did a full system backup/system wipe/cache wipe then installed xboarders 1.2.2 rom for the first time. I'm rooted! woohoo! I want to install eaglesblood new rom now. My question is when installing a new rom is it recommended to do a full backup or is one time enough? Thank you for any help as I am a newbie at this.
I always keep at least one or 2 backups of setups that I know work. That way if I screw something up while tinkering with my phone I always have a working backup to fall back on.
So yes, its recommended to keep a good backup on hand. You don't necessarily need to backup every time though. I just make sure I backup my texts before I flash anything. I hate losing those.
What you DO NEED to do EVERY TIME you flash between completely different roms is do a full wipe before you flash the new rom. If you're only updating to a new version of the same rom then a full wipe isn't necessary.

Thanks for your help! Also, when doing a full wipe do I need to do a dalvik wipe as well in the advanced settings in CWM?

I always do. It certainly wont hurt anything if you do. Just remember the first boot after clearing dalvik cache usually takes a little longer than normal because the phone has to rebuild the dalvik cache. Don't panic if it takes a few minutes even to boot. After the first time it wont take as long.

Sorry, this might be kind of a noob question, but i see build 23 is out for CM7. If i flash the new build, do i need to totally set up my phone all over again?
My last experience with CM ROMS on my G1 was that if you are upgrading to a new CM version a wipe is recommended but not necessary. However, if you do not wipe and experience problems it will be the first troubleshooting step suggested to you
YMMV on the MT4G builds, but that's how it worked with the G1

Thanks. Ugh, i didn't even think about that when i flashed CM7. Seems like it is a real PITA to wipe every time and have to configure all the settings again.
I had good success on my move from stock -> Ice Glacier (un-crapwared stock) by making a full TitaniumBackup of -everything- and then restoring it app by app (along with settings). They are similarly built ROMs, and it worked well for me with minimal downtime. You may want to consider trying that if you are just changing between CM flavors, as I would presume they are mostly backward compatible with a few fixes/features here and there. At worst it may leave you with just system settings to redo.
When i flash a new CMNightly all i do is wipe the cache and the Dalv/Cache and i've yet to have any problems. If you are worried about wiping and restoring everything. you might want to look into Titanium Backup.
thanks. I flashed without wiping and it seems to be fine. I was worried more about my system settings than apps.

Wiping the Cache and wiping the Dalv Cache will not reset the phone. Only a full wipe will do that.
To my understanding, a "full wipe/factory reset" in Clockwork Recovery will only clear /cache, /data, and Davlik cache. /boot and /system will not be touched. Some users moving from Froyo to Gingerbread have had problems with /system, and a wipe of /system (from within Clockwork Recovery or from adb) has solved some problems for people, beyond what a full wipe can do. Discussions are in the CM7 thread in the Application Development subforum.
I know, most people refuse to search for anything.
i usually wipe the Cache and the Dalv Cache when updating nightlies, but several times i've wiped nothing and just flashed the new one on top and its always worked just fine for me
I always do a full wipe when installing roms. Setting it up each time makes me think its a whole new phone which is cool.
You do NOT need to wipe when upgrading to a new version of the same ROM. I've probably flashed 10 no-wipe updates of cm7 on my phone and it's still perfectly stable, no force closes or anything.
Boot into recovery and wipe cache and dalvik cache before flashing. Give it a few mins to "settle" on the first boot, reboot again and you're good to go.
Worst-case scenario you'll just wipe and reflash anyway, and nothing lost.
I have looked at the forums for a long time tonight and im pretty sure the answer is somewhere but i havnt found it. I am trying to install the LeeDroid Rom, this is the first time I have ever rooted a phone or considered installed a custom rom. I am confused about the wiping data portion. I installed the Super Wipe" script but i havnt ran it yet. My question is, do I need to wipe anything else? Like I see an option to wipe cache partition - do I need to do this also? Or will super wipe clean it all out?
Super wipe should take care of it all.

Ensure you have backed up everything (using Titanium, clockwork, etc)
then flash Super Wipe, this should get rid of everything.
Flash your ROM (check MD5 first) and any chosen MODS (such as no-sense, CRT screen etc)
Then wipe cache and davlik cache, re-boot and everything should be sweet!
alright thank you
So I'm familiar with flashing, just not with the tablet. What's the accepted method for flashing from 1ROM to the next? With my phone I generally flashed back to stock using ODIN. Is it OK to simply jump from one ROM to the next?
Thanks guys.

The same method for your phone is generally the best way to do it on a tablet as well. You "can" jump from one to another, but you always run the risk of file pieces getting left behind or random little bugs cropping up and such. For that reason, it's always best to do a full wipe, factory reset, wipe cache, wipe dalvik cache, and then flash the new ROM.

Formating /system, /data and /cache is sufficient. Factory reset could compromise your /sdcard and /sd-ext (if any) data, depending on the custom recovery you're using.

I just want to be clear, im to understand that all I really need to do is a fact data reset, and wipe everything from recovery? if thats all there is to it then freaking sweet. flashing to ODIN and going through the motions gets annoying.

I have always done this with the express intent to wipe everything clear and reinstall all apps and data fresh once I'm on the new ROM, but this has never messed up my CWM.

Yeah, I feel your pain. I love my SGSII and my wife has my old Captivate, but the ODIN stuff all the time did get kind of annoying. Luckily ODIN and a homemade jig are a lifesaver if you ever screw anything up though But yes, flashing to a new ROM on the tablet is pretty simple and doesn't have a few of the extra steps you have to do on certain phones. Just back everything up on your PC first, then I generally like to type out a list of all the apps I have on the tablet to redownload afterward, then wipe it all and flash the new ROM, then start downloading stuff from the market again.
Sorry if this has been covered way too many times but I want to make sure.
I have rooted my phone that was running 3.20.502.52 with the AAHK so now I'm on the version it sent me back to and I have done nothing since. I am getting ready to switch to the Jellytime R29 ROM. I know to make a Nandroid backup but I was a little concerned about getting back to the state my phone is right now should anything go wrong or if I don't like it, go back. It seems that I can't just restore my Nandroid through CWM without flashing a different kernel since I'd be coming from a JB ROM.
My current setup is:
Android: 2.3.3
Sense: 2.1
Kernel: 2.6.35.10-gd2564fb
Software 2.47.502.7
So, in order use my Nandroid in case the Jellytime messes up, do I simply have to do a factory reset, and wipe cache, and dalvik-cache (this is considered a "full" wipe, yes?) and then flash a compatible kernel then restore my backup? And if so, can I find that exact kernel somewhere to flash or is there another one you guys can recommend me to use in my situation? OR, can I just straight up restore the Nandroid since the backup should cover the kernel too?
Sorry I'm a newb. I'm trying to learn. All help is greatly appreciated. I'm hoping to flash Jellytime as soon as I know how to recover from it.
1. Welcome!
2. The kernel is included in the backup. You also don't need to wipe anything; just restore the nandroid. Make sure you use a fully updated recovery; make sure using ROM Manager for CWM or the 4ext Updater or Play Store app for 4ext.
3. A full wipe is system, data, and cache. Dalvik is already included if you wipe those. A factory reset only wipes data and cache, leaving system unwiped. In 4ext just choose "wipe all partitions except sdcard."
Alright. I already flashed Jellytime a while ago and so far I see no reason for wanting to go back although I did a quadrant standards test and scored lower than stock. Not sure why, but either way, this was a nice first ROM. What I wiped in cwm was the reset, cache, and dalvic. So far everything is working if I missed anything.
Didn't know wiping wasn't necessary for using backups. Must of missed that in my reading. Thanks though. I'll become less of a newb over time.
This is probably the wrong place to ask but I wanted to know what I should be wiping in TWRP before I flash a new ROM. It's been a long time since I flashed a fresh ROM (I'm on CM11S for quite some time) and I can't remember what I wipe to give myself a clean start.
Thanks

Depends what you mean by clean start, if you mean you want fresh out of the box experience (no apps, no pictures, no anything etc) goto advanced wipe and select everything apart from USB-OTG.
If you want to retain all of your media (pictures, videos etc) the standard wipe in TWRP should cover you (wipes dalvic, cache and data), you don't need to wipe system as TWRP will wipe it automatically before it installs any custom rom.
Thanks. I do want a out of the box experience but with CM12 nightlies instead of CM11S. It's been too long since I flashed anything to my device...

Wipe system, data, cache, dalvik cache.
