Help flashing roms?

[brad2taylor]

I think something is going wrong in my flash process. I start from my nand backup made before first root (after install of team wins recovery.) I then install a ROM (currently helicopter Aug 9 update) but no matter what the ROM all of my programs and settings are there at boot. Is this right? If not what is the process? And how do I correctly restore my apps and settings on the new ROM?
Thanks in advance for your help!

The general process is to nandroid backup all partitions before making any changes.

The /data partition holds all application settings and all android settings.

The process to install a ROM, reboot recovery, wipe /data and /cache. Wiping /data will wipe dalvik-cache, battery stats, rotation data, etc.
Install the ROM and reboot. First reboot will take a lil longer as android rebuilds your dalvik-cache.
Now, if ROMs share the same base, i.e. you switch from one sense based ROM to another sense based ROM, you *might* be able to get away with not wiping /data. It really depends on the details of the previous ROM loaded and the new ROM loaded. But if you switch from a sense based ROM to a real AOSP based ROM (example: CM7), you will definitely experience bootlooping. Hence, it is commonly best practice to wipe the /data partition whenever switching between ROMs as it will remove any possibility of bootlooping from /data issues.

Hope that helps!

Thanks for the info, but my question is what is the recovery process???

It seems that after the new ROM is flashed you can:
1. Restore contacts and calendar from google.
2. Restore apps from market. What is that process?
3. Restore data for apps and system. What is that process?

Thanks for any help! Longtime WM user, first android phone.
