On flashing between roms.

I know to do a system wipe/factory reboot, but do I also wipe the dalvik cache every time?

It's the safest way to do it, yes. If I were you, before doing anything, I'd install Titanium Backup and create a backup of all of you installed applications. Then, I would create a Nandroid backup for this current rom.
Each time you install a new rom, install Titanium Backup and restore your applications. Then, finish it up by creating a Nandroid backup. In the end, you can just flash between Nandroid backups to switch back and forth between roms that will contain all of your applications and user data.

Alright, cool. I do make nandroid backups for everything and I use Titanium. I just wasn't sure on wiping Dalvik everytime. Thanks!

When flashing a new rom

I know you should make a backup. So when you wipe and flash a new rom and kernel, do you restore data and that will restore all the programs you had prior at the time of the backup?
Thanks.

If you do an advanced restore of your data through CWM recovery, yes it will restore all your programs and settings. However, this can cause problems as the old data does not get along with some ROMs.

So it is best to just reinstall programs?

I would use Titanium Backup or My Backup Pro to back up you apps+data. After the flash you can either restore everything from the backup or just the data. Some people have said that it's best to re-download your apps from the market and only install the data from the backup (as opposed to restoring app and data). I don't know, I've done it both ways and have never noticed a difference.

[Q] Does flashing FR008 wipe all my data?

Does flashing this rom wipe all my data??
Will i lose allm y contacts, messages, settings etc???
If so, how do i backup all of this stuff first?
I currently have rooted with clockworkmod and am wanting to upgrade to 2.2 for apps2sd and openGL ES 2 etc

Yes the recommendation for flash Liberated FR008 is to do a Wipe Data from ClockworkMod before flashing.
You should sync all of your contacts to Gmail using your Google account to preserve them and since you are rooted, you can use Titanium Backup or My Backup Root to save your apps, setting and messages.

Can I flash without wiping data, as the tutorial only says its especially reccomended if im coming from another ROM.
Currently I only have to stock at&T Rom (with some at&t apps removed) installed on my phone

You are coming from a Android 2.1 ROM and flashing an Android 2.2 ROM, so it is a different ROM. This is not a ROM that was made from a 2.1 to 2.2 OTA, so I think the best thing would be to do a rooted backup and then wipe before you flash. I would make a good nandroid backup using ClockworkMod before you flash, too.

What is a rooted backup??
Yeah Ive done a nandroid backup. Is all I need to do is to root with clockwork, then nandroid backup, then install the rom?
I dont need it nand unlocked or anything? Also, is it easy to restore from a nandroid backup?
thanks for your help

A rooted backup would be to install Titanium Backup or My Backup Root to back up your apps, data and settings. You would install these from the Android Market after you have rooted your phone.

No, I suggest that you then backup your apps, data and settings using Titanium or My Backup and then wipe data as per the instructions for flashing.

Yes, when you select the Nandroid option in ClockworkMod, there is a menu selection for both backup and restore. A nandroid backup is a complete backup of your phone that you can restore and go back to if you don't like the new ROM that you flashed. It will restore your phone to the exact point it was before you flashed.

Okay thanks I might try this after work.
Also, waht is the most stable release of Froyo (with HTC Sense) for the Aria?
I've heard that FR008 can have problems with the reception after a flash.
I guess i can always flash it and see what happens and then restore back if i dont like it.

I have not had any reception issues when I flashed Liberated FR008. It runs just fine for me. I have a WiFi connection both at home and at work, so I leave WiFi all the time and I am very pleased with the battery life.

what does nandroid restore??

for example, if i back up my VI rom through the recovery and flash a new rom to test it out ( lets say skytouch 4g ) and go back to vi, when i restore my nandroid, will its restore my phone to the way it was before backing up? (apps, data, settings, texts ect.)

Everything is backed up.
When you restore it will all be there. Interestingly, Titanium Backup can pull apps from a nandroid to restore them to a new ROM. Careful though, as that can be more trouble than it's worth.

Yes. the nandroid backup contains all partitions. The restore allows you to set the phone back to it's state when the backup was taken. I recommend performing nandroid backups at regular intervals as a best practice for easy recovery just incase something happens to your config.

[Q] TWRP Recovery- How to use?

So I am currently on Paranoid Android and wish to switch to another ROM (most likely AOKP or PACman just to try). In TWRP recovery, what would I select to just back up my app data and NOT my ROM, and after that is possible, what must I restore to get it back and in what order of flashing alon with my new ROM and GAPPS???:silly:

You can go into TWRP and backup and choose what partitions you want to backup. However, I'd suggest you backup everything and don't try to restore the data to another ROM.
I use Titanium to backup all app data as well as MMS history, WiFi networks etc then do a full backup in TWRP. Then wipe everything and flash the new ROM. Then boot up and reconfigure accounts and restore apps + data with titanium.
It may be a little more effort but this way you can always roll back to the previous setup if anything goes wrong and you're less likely to run into any weird issues from moving data around between ROMs.
Or you could try something like app2zip off the play store to make a flashable zip of only selected apps and data which is probably safer than the whole partition. If you do a full backup first you can always rollback if something goes wrong.

When using Titanium Backup, when I hit run backup, where does it go and how do I restore it after I flash my new ROM. Or do I do the update.zip option and flash that when I'm doing my new ROM?

It goes into a folder on /sdcard called TitaniumBackup. When you flash a new rom, you will need to redownload titanium backup. When you redownload it, it will find the backups and you can click on the app to restore it.
Theres no need to use the update.zip method. Do it like this ^
