Quick question about switching ROMs - Galaxy S III Q&A, (US Carriers)

If I am switching ROMs of the same build, lets say CM10 7/23 build to a future unofficial CM10 build, would it be necessary to do a data wipe and factory reset?

Necessary? Probably not. A good idea? Probably yes.

Okay so similarly if I go to CM10 from another Rom wipe data and reset... but if I backup my with Titanium Backup what is recommended to be restored after flash? All system data + apps + app data, just apps and data or just apps. If I have contacts backed up to email etc, photos and such data stored elsewhere... would it be recommended to use the least amount of data restored from last install to the new Rom? I just donr want to load wrong values upon restoring my apps. I don't mind if app data or system data is factory reset but not if unnecessary and only if its not a prob and won't mess up any Ron specific settings.

[Q] Restore applications and settings after 1.4 upgrade

one quick question in setting up the upgrade from 1.3d to 1.4:
When using Titanium Backup, I back up all user apps + system apps.
Once upgraded to 1.4 can I restore also system apps, or I can mess something doing this? It's better to restore only user apps?
Thanks
You don't need to use any apps to restore after upgrade. All the apps should still be there if u only did an upgrade without a reformat factory settings
Thanks but if I understand correctly the Dexter's instructions, he recommends to do a Wipe (Factory Reset) before and after installing the ROM. In such a case, I guess that all apps and settings will be lost. And then, it is when I gess I need to restore from a previous backup or otherwise I would need to restore everything manually, app by app.
Even if you don't wipe out you apps and data, it maybe be better if you do a backup in case something goes wrong... Bad things happens when we least expect
OK, but my original question remains:
Once upgraded to 1.4 (and making a wipe) can I restore also system apps by using Titanium Backup, or I can mess something doing this? It's better to restore only user apps?
What system apps that you want to back up with Titanium? I recommend you to check the change log from each of Dexter version to see if any of your system apps is being changed in the new update or not. If it's changed in the new update then don't back up it, otherwise it's safe to do so.
OK, thanks. That's what I did.
Since after installing the ROM, all applications there were the ones coming with the ROM, I didn't restore any existing app, assuming it is already the last and correct version. I was therefore restoring only those missing, and it worked fine. The only problem, I guess, is that by doing this way I didn't restore the app data for those apps coming with the ROM. Not a major problem.

[Q] Data backup switching to Gingerbread ROM

I'm running veganTAB 5.1.1 at the moment. I've installed a lot of apps, have some documents stored locally, a lot of data in springpad as well as a good number of media files.
I know switching to the ginger edition requires a wiping data. I have titanium back and ran a full backup of apps and data.
What I'd like to know is the best way to go about restoring my apps and app data and whether I'll be deleting any locally saved files when I "wipe data". I guess i'm not clear whether wiping data means wiping everything, like a reformat, or if it means a specific menu option in clockwork.
I'm a bit of a noob at this still. I have reflashed roms a couple of times but at the time I didn't have a lot of stuff to worry about saving and I'm not sure whether I wiped more than I needed to.
A data wipe will erase user installed applications, their associated data, and system data (but not system apps). It will not harm files stored on sdcard or sdcard2.
Does restoring the apps through titaniumbackup work? I seem to recall trying that once and the app didn't work until I uninstalled it and redownloaded from the market. Maybe I did it wrong.
Restoring apps and data should work. Do not restore system data or you will have trouble. It is quite possible that you'll have to reinstall Titanium Backup to make it work correctly. I've had to do that once or twice when changing ROMs.
Smooth and easy, not sure what I was worried about. Thanks.
I just did the same thing and had real good luck with app mybackup, I just backed up the apps and no data and it worked perfect. Gingerbread was very nice roms. But it seemed the more programs you load the longer it takes to boot. At first it booted in a few secs. Then I did my restore of all my apps and it took like 5 min to boot all the time. Not sure what that was about.. But I switched back to TNT.
I have sold my Gtab to a friend and want to keep all my downloaded app's .
I can move them to the SD card and do a data wipe in CWM and it will remove my personal data like passwords and facebook ,, gmail account ?
and still keep my apps ?
Thanks

Help, Apps on cm7 keep force closing

Hi,
I accidently posted this question in the general section, but i think it is more appropriate here. I am running the 07/18 cm7 rom, and after a seemingly random amount of time (anywhere from instantly to 24 hours) after a reflash, or nandroid restore all my apps begin to force close, generally starting with gapps. once the apps start FC there is really no recourse but to restore the phone or try to reflash. i have tried wiping the cache and dalvik, both individually and together, as well as fixing permissions, but none of these options resolves the problem. I have also tried installing all my apps via the market to see if it was titanium backup corrupting backups, but again the phone started crashing. For the life of me i cannot figure this out and i was hoping that someone smarter than i could lend some insight.
Thanks
Same here
I'm actually getting the same problem! I have no idea what the problem is. At first it started with Gapps FC-ing, and now pretty much no apps I have work. Even my Gizmodo app, which is really just a link to the Gizmodo website.
Any ideas?
I tried rebooting .. It works for a little while then the problem continues.
Not sure if your cases are similar to mine.
I made nandroid backup for CM7 and flashed Vanilla GB with wiping dalvik/cache, but without wiping data.
Without wiping data, VGB showed continuous error messages related to foce closing...
Again wiping all three fixed that issue. So wiping data may be necessary.
After restoring my old data with nandroid (data only), it happened again.
I reallized that nandroid restoring was really painful with CM7 or VGB.
My final solution which worked fine was Titanium Backup for restoring old data rather than nandroid.
Nandroid backup is working fine when converting all system, for instance, from CM7 to VGB or vice versa, with wiping data.
Even in this case, you have to restore contacts and calendar separately to SD card using export option.
Nandroid or even Titanium Backup didn't recover my contacts under CM7 or VGB environments.
Hope to help you.
You should always, always wipe data, cache, and dalvik vm cache between flashes, especially if going between roms that utilize different file systems. Otherwise it will be fc city. To fix yours, back up your apps with Titanium, boot into CWM and wipe data/cache/dalvik, reflash ROM and gapps, then boot up and restore only user apps
(not system apps).

[Q] Installing new ROM and Kernels

I just recently rooted the phone, and was not planning to replace the stock ROM, but in the last couple of days, I've been reconsidering this. BUt I do have some questions:
1. Can the new ROM be flashed as an "upgrade", IE, not loose everything and have to re-install apps.
2. I've had my eye on the Shooter XE or the Olympus XE ROMs, the instructions say I need to do a complete wipe before installing. Is that necessary?
3. What about updated Kernels? I'm curently running 1.11.651.3, and there's a newer version available here (Stock 1.13.651.7). Will updating to this newer kernel mess up my existing data?
4. Is there a way to backup all my apps, settings, data etc, then restore it all automatically. Titanium Backup can let you back everything up, including all the system bits and pieces, but how do I know what to back up and restore without doing any damage to the new system (like over-writing new settings and files with old ones)
Yes you must do a full wipe when changing ROMs. If you are installing a newer version of the same ROM then you can just wipe cache and dalvik cache and you won't lose anything. When using Titanium Backup it is a bad idea to restore any system apps. Stick to backing up and restoring user apps only and you will be good to go. It may backup the system apps, but I would advise to only restore the user apps. As far as your settings go, your Google account keeps them backed up if you allow it to and will restore them to your new ROM if you choose that option. Every ROM has a kernel. If you are flashing a custom kernel then just wipe cache and dalvik cache and flash the kernel. You will not lose any data when flashing a kernel by itself.

[Q] ICS switch builds: wipe or not, is titanium safe

Wanting to switch between Turl and jokersax ICS builds.
Is titanium confirmed 100% working on ICS? i.e. I can do a full wipe data, format system, data, cache, dalvik, flash and then restore missing apps/system settings via titanium?
Or just restore individual apps (not system settings)?
Or is it safe to just wipe cache/dalvik and flash over?
Anyone that switches between the two, much appreciate your feedback.
Last time I did so I formatted everything for clean install, but I had just been running jokersax for less than a day so didnt care about restoring anything. However now I have turl setup nicely and don't want to have to bother redoing my homescreen, apps etc.
TiBu worked fine for me on both.
You should however never restore system settings after flashing a new ROM. Even though both CM9 versions are very similar, you do not know exactly what is all different, and may cause issues.
Better to just create a nandroid backup of each one and restore from those.
