Okay so, Right now im using CM10.1 Nightlies and i want to update from that to aokp_primoc_unofficial_Nov-18-12. Do i have to wipe data??
IF so how do i keep ALL my files?
Yeah the best hing to do is a full wipe. You will keep all your data stored on the SD CARD but you will lose your apps. If you want to be able to restore your apps after flashing your New rom I suggest you back them up with apps like titanium backup or carbon BEFORE you do a full wipe

Can someone explain a few things about backups and ROM flashes, please?
I've got a custom ROM on my Desire, and I'm using an Ext partition to hold my apps using App2SD.
I've run a full backup with Titanium Backup.
If I want to wipe and flash a new ROM, how does it work?
I do a factory reset, wipe cache, wipe dalvic.
I then flash a new ROM. New ROM will presumably be faced with the apps I've already got on my SD card ext partition.
Do they just install back, or do they cause problems?
If I reinstall Titanium Backup on the new ROM and restore everything, do I end up with new ROM and all my old apps back as they were before?
Or do I need to wipe the ext partition too, before doing a restore?
Any pointers would be great.

Doing a factory reset wipes all apps so if you do that before flashing the ROM all the apps will be gone from your ext partition.
You can then restore your apps using titanium backup. Be careful though, your market apps are fine to restore but you should be very selective about restoring system apps. I only restore data on the green coloured system apps to get back things like SMS, my custom sense layout, that sort of thing.
If you go from sense to non-sense ROMs then you may not even want to do this much.
Somehow the backup went like over 1GB and fully fill up my memorycard.... I notice the backup also include "DATA" as well..
I just want to backup my ROM data so I can have a fresh copy of my stock OS if I need it in the future.
Is there a way?

What do you mean by "data"? Perhaps you can borrow a bigger microSD card to make a complete backup
You say you want a clean stock backup? Just wipe everything (data, cache, dalvik...) and then make the backup...
I rooted my Evo a while ago. Now I want to try a different rom and I am not clear about somethings. If the new rom requires a data wipe how can I migrate my data to the new rom?
I can use recovery to do a full backup then wipe and install the new rom. Can I then flash my old data back? Or would that not be considered a wipe? In other words does a wipe for a rom require all new data or is it OK that the data be "reinstalled"? Is the issue the actual contents of the data or the location in flash of the data partition?
If I can't use my existing data with a new rom is Titanium backup the only way to migrate existing data to a new rom?
Second, and related, is a basic question about partitions. If the size of a partition is fixed, at least at installation of a rom, then is there any benefit in deleting bloatware? If I install a rom that still has some sprint apps and then I delete one do I get that space back? Or is the size of that partition fixed so the deleted space is now empty but not available to my data partition?
Finally, if I install a rom that has new versions of an app is there an easy way to tell and to delete the version from data? For example if i have Google maps in data and then upgrade to a rom that has new maps how can I tell which is newer? Can I just uninstall the app in market, if the data version is older or the same as the rom?
Thanks for help with these basic questions.
I realize that I am missing a basic understanding of the "disk structure" of android. But I have not been able to figure out a good source to explain this.

Contacts and calendar should be backed up to google, as long as they are "google contacts" and not "phone contacts".
Texts can be backed up with SMS Backup and Restore.
Pics should obviously be on the sd card.
Apps and their settings can be backed up and restored with Titanium Backup.
Using the above things, the ONLY thing that you should have to setup when flashing a new rom is: first, your google account, and then your homescreen layout and system settings. Keep in mind, Titanium will back these up for you, but this is NOT to be used to restore between roms, it is only to be used within the same rom. If you try to restore system settings and home screen layouts between roms, it will mess up the rom.

No, as that would defeat the purpose of wiping data in the first place. I know it's a pain, but you NEED to wipe data when flashing roms, if you dont you WILL have many problems with the new rom. I've got it down to about 20 minutes from flashing a new rom to being fully set up again.
Will i lose all my internal data like game saves, etc? Is there any way to back up app data as well?
Use titanium backup to backup your user apps.. Then when you install CM10.1, you can wipe the data partition to avoid problems later on. Once installed, reinstall TB and restore your user apps.
notice he said "user apps". Do not restore system apps.
so internal storage isnt wiped if you go from fl16 to cm10.1?

Mine was when I went form FL04 to AOSP. That's because I did it myself though. I think it's generally recommend that you do wipe your user data. You can always back it up on a computer then restore it after you finish everything else. I suggest waiting and doing that last in case you need to reflash or decide to change ROM's.
Hey,
I an trying to wipe my ROM and reinstall a fresh ROM. In TWRP Recovery, if I hit wipe system and data wipe, will that effect my back-ups on TWRP? Trying wipe the current one and restore the very first backup after installing the revolution HD M8 9.1 .
Only wiping Internal SD will wipe twrp backups. So wiping system, data and caches should be fine.
Sometimes things go wrong though. Good to have a backup of a backup off the device. And/or another rom zip. Titanium backup backups are good to store off device too. And pics, etc.
Bad things happen... And it's a drag when all your stuff goes away. :good:
Storing things as backup on an external sd is good too... But not fool proof either.

Agree to all the above. Always give yourself multiple ways out of a jam; and taking a few minutes to backup off-device is a great way to avoid regret and headaches.
