So when i move to a new version of a rom, how do i keep all my info? I was just used to backup/restore with a rom version change on cyanogenmod where i can restore and it won't overwrite the previous rom and revert changes.
Do i always have to wipe all data when uploading a new rom?
Shouldn't the nandroid backup restore everything but keep the current rom?

I learned this today myself.
General rule is:
Switching ROMs? Wipe everything
Updating a ROM? Wipe cache and dalvik-cache
Installing an addon? Don't need to wipe anything
i guess that answers part of my question. the main part was when i switch roms, how do i keep all of my info? when using cyanogenmod, i could back up using nandroid backup from recovery, and restore when i installed a new rom, however it seems with some roms i cannot do this as it will overwrite changes in the new rom. how do i avoid this, how do i keep all of my data while not overwriting the new rom changes?
I'll try to answer your question, if I think I know what you mean by data. Data from ROM or data from phone/apps.
If data from phone/apps. then I would suggest Titanium Backup(Paid version) from market. Once you install a New ROM with a complete Data wipe, what ever you backed up with TB from your previous setting can be restored. This is good if you are installing a ROM not from the same dev.
Other wise if you installing a ROM from same dev, a revision, you don't have to do a wipe data.
If data from ROM, well I don't know there, never had to do it.

ok, so you're saying when, let's say, going from 1.0 to 1.1 of the same dev rom, just an update, i do not need to wipe data?
Yes. The only time you ever need to wipe data and cache is when you trying a ROM from a different dev.
If installing a different rom, then that's where TB comes in handy.
Side note: Also CWM ROM Manager backup utility will backup every thing if you wanted to revert back.
Dayton advice above is a good rule to follow.
There's other bits and pieces but search or ask.

Rooted p-5100 10 inch tab2 and flashed cm9 and love it but now need to try cm10
1-how to transfere from cm9 to cm10 ?
2-we need to flash cwm 6.01.0 right?
3-we flash cwm via oden or cwm 5?
4-we need to flash a different version of gapps right ?
5-do we need factory reset and cashes erase if transfere from cm9 to cm10?
Mohamed Selim
while flashing the latest cwm(from a zip is fine) and factory restoring before changing to a different major version is recommended, it isn't always necessary.
for me going from cm9 to cm10 it was no problem to stay on an older recovery, and keeping my data.
but if you experience problems after updating it's best to do a factory restore, and it never hurts to have a more recent recovery.
as you mentioned you do need JB google apps.
and while wiping cache is often recommended after flashing a new rom, it's usually not necessary unless you experience problems.
if you choose to keep your data and cache you shouldn't expect support from developers here though.
Hi, I am currently running stock TouchWiz 4.1.2 ROM, using CWM Recovery, I tried to install the Pac-Man Rom, but after phone rebooted it kept hanging on the PAC-MAN image with the ghosts, phone hung there for a bit, tried to reboot "removed the battery", went back to CWM Recovery, reflashed the Pac-Pam ROM and latest gaps, rebooted phone and the same thing happened,at some point it wiped out my CWM recovery, so I got fed up and reinstalled the TouchWiz factory 4.1.2 image using ODIN, had to reload all my apps and what not.
I want to give this one more try, but do not want to go through all this trouble again. I did a casche wipe and devlick cache wipe, but no data/factory wipe "heard people had success with a dirty flash routine", do I need to do a factory/data wipe for this to work.
I am not new to flashing, but have not flashed a non stock ROM yet, kind of leary after the PAC-Man fiasco, by the way what do you guys think of Cynogenmod or AOKP. Do I have to wipe all my data every time I try a new ROM. Is there a stock, pure android JB 4.2.2 ROM out there. Thanks again.
You have to wipe data/factory reset before flashing. Two different bases. One heavily nodded framework to stock(ish) won't work. Also, if you use something like titanium backup, you don't have to worry about losing things as much.

He is saying do not dirty flash ROMs you MUST do a factory reset as none of these ROMs are the same. By dirty flashing you are flashing one ROM over another which is a boneheaded move as you are likely to be stuck on the bootloader. The ONLY time you should dirty flash is when you are flashing a newer version of the same ROM.

Thank you sir, don't be angry at me, by the way it is much appreciated.
Basically. Don't dirty flash an aosp ROM over a touchwiz and vice versa

Also don't dirty flash if the Android version is different.

My advice is to do a clean flash every time, and also a full backup. Here's what I do -
- backup all apps using your choice of app - I use MyBackup, there's also Titanium, Rom Toolbox and many others
- backup all sms, call logs
- backup launcher settings
- nandroid backup
- factory reset, wipe system/boot
- make sure you don't wipe internal or external sd card
- update to latest radio or rpm if needed
- flash rom
- flash kernel if needed
- flash gapps
- setup new rom, don't let google restore apps
- install your backup app and launcher
- restore apps, sms, calls etc
- restore launcher and android system
once you get comfortable with this procedure it doesn't take long. And it guarantees a clean phone with the latest apps and new rom with no issues.

Ok everything went fine, installed the Pac-Man ROM 4.2.2. seems much smoother and faster, my first question is how do I enable car mode where all my text messages are spoken out when received, including phone calls, my other question is now my screen is more cluttered by the on screen buttons at the bottom, the back home and systems button. The full clean wipe did help, thanks again.

Sorry, I recently posted this in the wrong section. Mods feel free to move/ erase as you see fit.
I am needing advice with backing up my Cyanogenmod 11 stuff. How do you guys do your backups, enabling you to flash a newer version etc and not lose your data and setup preferences?
I flashed CM11-0303 (and appropriate kernel), then did un update to 0307 and re-flashed the kernel again. This causes major issues and I had to reflash 0303 again from scratch. I was going to only start updating with official CM updates but apparently you can't install an official release update over a nightly install. Is this true?
Thanks, my phone is an S4 i9500. Hope you guys can help because I now want to reflash a new official release without losing my data and setup preferences :good:
Do you guys backup within the system recovery? Do you backup to your phones internal storage or to the SD card? I am using PhilZ Touch 6.19.2.
Thanks
If i clean flash a new Rom but restore the data part from a backup i did earlier from another rom from recovery will it work? Im using TWRP recovery.
ive always had mixed results on this. if youre going from a TW ROM to an AOSP or AOKP rom, likely not. If you use TiB and backup your apps and their respective data, and restore them via the same method, that 99.9999% of the time works
