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

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.

I was wondering how I could update my cyanogenmod 10.1 build 16 to 17 without wiping my phone. Any help is greatly appreciated
AW: Updating Cyanogenmod
You could try only wiping cache and Dalvik cache, that mostly works
ok will that delete all of my apps? and then do i just flash the new build to my phone?
AW: Updating Cyanogenmod
No, your apps and settings will all still be there. Yes, afterwards flash the new version as normal and don't forget to flash the new boot.img if you're s-on.
ok i will do thanks for the help
But do not complain about problems, it isn't called dirty flash for no reason...
A clean full wipe flash is always safer if you want to avoid problems, especially when there are new minor Android releases or greater CM changes
Hello everyone,
Currently, i'm using the 'HyperSensation' ROM which is based on CM 9. But now, i want to update to CM 10.1, and the only way i see to do this is to flash the original CM 10.1.
As known, if you update your ROM, it's possible without wipeing / loosing data.
But now, if i "update" to the original CM, is this possible without wipeing?

As it's a different base you should't flash CM10.1 over ICS
Just use titanium backup and Sms backup app then Do a wipe All except SD card in recovery and flash ROM & Gapps and PROFIT !!

I don't know how this ROM is based, but since both are based upon CM (well, CM is CM, not based upon), This might be possible.
However, since you (might) want to flash CM10, it's advised to wipe. You can back up your apps and data with Titanium Backup.
Thank you 2, the tipp with Titanium Backup was worth it.
Glad it worked for you
I am running CM-11 Stable version, which means I am rooted as well as custom recovery. If I update my ROM, will I loose any of my application's data?
e.g. if I upgrade to CM-11 Nightly, will be there any loss of data. Or if I want to install some different ROM's will there be any loss of data.
Is it possible to switch back to Stock ROM (Rooted) without loss of data.
Actually managing phone's data is big pain once you reinstall whole OS, So I am really doubtful here.

Do you mean with data your storage or your apps, settings? If you install a new rom you always need to wipe data (that is not your internal storage). If you update you only need to wipe cache and dalvik. You can backup apps easily with titanium backup for example
You should always nandroid backup before flashing roms and always keep a local copy of a titaniun backup.
Flashing custom roms dont wipe data. However, you may have to wipe data yourself to get it to boot.
Rule of thumb is:
Upgrading to a new version of the SAME custom ROM, no need to wipe. If you then find something doesnt work, wipe
Changing to a NEW rom, wipe.

So, I know that OTA will fail since I am rooted. I am on a Sprint S6 with OC9. I rooted using the T-Mobile Auto-Root.
I see that OCF was published for Odin to flash back to stock. My question revolves around the recommended procedure for flashing with stock. I use Titanium Backup. If I backup, then flash OCF, will this also erase all data on the phone to the point where I have to restore all backups and customize the phone all over again? There's just some things Titanium can't restore well. Or is there a way to update the ROM without wiping everything (dirty flash)?
Given the phone has built-in storage and no microSD, does the storage partition ever get wiped unless I do it manually?
Also, is there any sort of change log for the stock ROM versions? Or do they seem to be just modem updates at this point?
I don't know much about this phone yet since I just got it but coming from a nexus 5 flashing a ROM would keep your data but in this case since it is a system image you will probably lose everything in your storage
