I've flashed almost every ROM available, both TW and JB, and I am curious if I just need to wipe everything 3x or if I should also format /system?? Also, when restoring apps with TB, is there a way to have it automatically add the apps to the homescreens as they were before?
Thanks!

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.
Is it posible to flash with data loss?
Or can i backup my apps data and then restore it when i flash to another Rom?
It's not possible to flash a ROM on top of a previous ROM w/o expecting any trouble. Either you get bootloops, hangs, or all sorts of force closes with apps. Backup apps w/ Titanium Backup. TB will save the apps and data to a folder on the SD card, from which it will restore the apps when you click "Batch Restore" after flashing a new ROM.
thanks for the advise gonna do it tonight

I've flashed about 100 CM7 nightly builds and release candidates on top of each other without losing data so that isn't strictly true! ROMs made by different chefs that are significantly different from each will need a data wipe though, and TB is useful to some in that situation.
Well i want to go from LeoMar75 Rom Revolution 2.1 to 2.2
I use rom manager and have sometimes updated my rom without wipping my data, but it's not always stabel.
I would recommend first making a backup of you data with titinium backup or mybackup and then updating your om

Sorry, I should've been more clear that when switching from one ROM to an entirely different one, you should wipe. But then again, even with ROMs that are of the same series, sometimes the differences are so great that it's best to wipe clean before flashing. I'm speaking from my experience with StarBurst.
Hey, I wondered if any one could help me figure out why about 75% of my apps ont work on a custom flashed ROM?
I have tried Revolution HD and some 2 others in the development thread. the ROMS themselves work perfectly fine but most of my apps force close instantly. when i revert back to the stock ROM everything works fine and my apps all work again. can anyone help???
Thanks
are you wiping everything, including data, and both caches when you install the rom? and how are you restoring the apps? titanium or something similar? or just downloaading straight from the market? if ur using titanium, make sure ur not restoring system settings OF ANY KIND.

Well I've used the revolution HD full wipe.zip which I would have thought wipes everything.
When it comes to restoring apps I've used my backup root and I've only backed up apps and media not system setting. Once I've restored them I've updated them to latest version if possible and tried to reinstall them which also didn't make a difference.
Not sure what I'm doing wrong.....
Thanks for the reply
Hi,
I was wondering: What is the reason when you flash a new kernel (BIOS) and ROM (OS) your apps can be still there?
Is it because the apps can be considered as portable programs - to use windows terminology - and anly some system folders are overwritten when flashing a new ROM?
Thanks,
TeTTiweTTi
when you install kernel, your apps will still untouched!
when you install new rom, your apps will be removed because this format the /system partition and wiping the data will remove your personal apps! but if you just made an update, I think your apps will will there.
As long as you dont wipe data or format system while installing a new rom then your apps will stay there but thats not recommended to prevent any bugs or issues that might happen to u.. Happy flashing

The best way to backup your apps is by using Titanium Backup. It'll backup all of your apps and their data, you need the pro version to backup call logs and messages but it's well worth it because the pro version also allows batch restore (without batch restore you need to individually press ok for each app that you're restoring). Titanium is by far the most important root app that's available. You don't need to backup your personal data (music, photos) on your internal storage because you don't wipe the internal storage when flashing a ROM.
When flashing a new ROM you need to perform what's called a full wipe, this is wiping system, data, cache, and dalvik cache. Using TWRP recovery (the best recovery) you enter the wipe menu from the main menu, then select advanced wipe, and then you can select the previously mentioned partitions to wipe. This does not wipe your internal storage (the user-accessible virtual sd card where all of your personal data resides), wiping the internal storage is never necessary when flashing a ROM.
If you're just updating the same ROM (flashing a newer version/build) you don't need to worry about wiping, you can just flash the zip and reboot. Only ever do this when updating the ROM you're currently using though, never when flashing a different ROM.
