[Q] upgrading roms

i'm using a htc desire running on cm6.
when there are newer versions of cm and i would like to update to it.
what is the best way of achieving this without having to wipe the data/settings/etc?
if there is no such way, what can i do to backup settings/data/apps so that once i update to a newer cm , i can just restore my stuff?
what about Rom Manager Premium, theres an option to check for rom updates, would Rom Manager update your rom for you?(and keep all settings/data/etc?)

Yup.
it does everyting. buy it. seriously.
vision

seriously?

i use titanium backup and it works fine for me..
another option to back up your apps & system data is the nandroid backup on the recovery menu..

titanium backup requires busybox and for that to work i need to be nand unlocked.(which im not).
i always thought that nandroid backup will backup everythign to a state, so if i were to upgrade roms, and then use restore, wont it just revert me back to the previous state(not updated)?

You are correct. A nandroid restore will undo your update.
If you're upgrading to a newer release of CM6, you should be able to do it without wiping your data. Wipe dalvik and cache, flash the rom, and reboot. You'll have new featuers but all your old apps and data in tact.
Nandroid backup first for good measure though

oh okay, so wiping dalvik and cache would just wipe all settings(including home screen layout, widget placements, folders etc?)
some tutorials that i've read about updating roms, is that i dont even need to wipe dalvik and cache, anythign bad about that?

Nope, dalvik and cache wouldn't even affect your settings.
The cache is the temporary cache used by the Android operating system, and the Dalvik-cache is the cache used by the Dalvik Virtual Machine. The only thing about wiping them is that the first boot will take longer as they rebuild their indexes and such.
Nine times out of ten, you'll be fine without wiping these. It's just generally considered "better" if you do.
Again, nandroid backup and try it out. If it doesn't work without wiping, restore back and wipe the caches.

installing rom question

Do you have to backup to stock rom or can you just install a rom on top on another without backing or w/e?

You should backup your rom before flashing, this way if anything goes wrong you can go back.
You should always wipe, wipe, wipe.
Wipe data/factory reset
Wipe cache partition
Go to Advanced and wipe Dalvik Cache
After the wipe go back and Install zip from sdcard. After install I do another wipe on the Dalvik Cache then fix permissions. Remember Wipe, Wipe, Wipe.

so as long as I do that then I can install a rom over another and delete the previous one while doing so?

I recommend making several backups.
First, make sure you have Clockworkmod installed via nvflash. Then make a backup. Download the backup to your pc for safe keeping (just in case things go wrong).
Use Titanium Backup (free version works, but buy the full one if you like it). Use the batch feature to back up all user apps. Do not back up system apps.
When installing a new rom, especially roms that use different versions of android, you should wipe everything you can except the external sd card (where you keep your backups). Wiping "system" is important.

If you wipe system you done loose data ... data here roughly means data partition which holds apps
it wipes only when you wipe data or a reset etc
in recovery you can make a backup of current rom ... you need abour 400 mb free space on sdcard
then try anything if it doesnt work out .. in recovery you can restore and nothing would be lost

you will loose your current rom not data ...
u see apps are in /data partition
and rom on /system ... so wiping system wont afftect /data
its like in windows when you reinstall windows ... only c: gets wiped rest like d: etc arent changed
for nandroid restore ... u can go in recovery > backup and restore ... there is an option for that

©FIRST & LAST >>WIPING/FACTORY RESETTING SYSTEM DOESN'T DELETING SYSTEM.
My dear bro.answer is very very simple
First thing- you want data but not settings right ?
Just go in recovery - go in backup section - backup whole system(do a nandroid bacup)
After that in main menu select -wipe data/factory reset and then wipe cache and dalvik cache also,Ok
Now you only want data and fresh system(resetted) am i right ?
Now go to backup &restore - select Advance restore - select restore data only - select your last backup.
After that back in main menu and select reboot system now!and voila system rebooted(takes about 5-7 minutes ) and you can seeing problem is gone and all data is intact.as it is.
Last but no least - some of your apps that you installed separately is in internal memory is gone due to factory resetting system.
So it is adviced do a titanium backup of each before doing above things
Btw,who tells you wiping system delets itself?
Press thanks if i helped you!

Backup and Restore

What do you guys typically do when you try out new ROMs and want to do a clean flash and get back up and running quickly?
1. Restore via Google
(Very slow to redownload everything, doesnt restore everything)
2. Sony Backup/Restore
(Sometimes Restore doesnt work)
3. Titanium Backup
(This is what I currently do, but can also be extremely slow)
4. Titanum Backup (creating update.zip for use in TWRP)
(Backup only seems to allow backup to internal storage so I run out of space)
5. Something Else

I use twrp recovery menu to backup my data, system and kernel
I usually backup to my internal storage since its faster than my mSD
From there i wipe and flash
Or to restore wipe and restore (since cache/art cache wasnt included in the backup)

If you wipe/restore from TWRP, then haven't you've just wiped your brand new ROM and returned back where you started?
My question is specifically for people who try custom ROMs do a backup and restore.

I think i made a bit of a typo there
when going to flash
- backup
- wipe
- flash rom
- flash gapps if needed
when going to restore
- wipe (cache, art cache)
- restore

I'm sorry, I still don't understand.
1. You backup (system, data, etc)
2. wipe
3. Flash rom (which writes new rom to system and data)
4. Then you restore your backup, which now overwrites system and data, thus erasing the new rom you just flashed
I need a way to restore apps and app data while keeping the new rom, otherwise it defeats the purpose

[Q] Things to backup in Nandroid Backup?

Hi, I'm a bit new to Nandroid Backup, so when you click backup in TWRP then there is "Partitions to Backup" options. I read a guide that you have to check Boot, System, and Data. The thing is, can I just backup System and Boot? And when I restore them does my phone will gone wrong?
Thanks

• Boot is to start the phone up. This is always needed.
• System is for the ROM. This is always needed.
• Data is for your installed apps and settings. Basically, if you backup and restore this, it will be like you used a time machine.
Every data backup is for its own ROM! Do not ever try to restore a data backup from a different ROM!
• Cache is basically the cache. It is not needed, but you can. It speeds up the startup after restoring. If you don't backup it, it will be recreated anyway but you have to wipe your old cache first otherwise they will conflict.
