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.

SGS3: Restore Samsung Apps removed by debloater

Hi,
Is there a safe way to restore Samsung Apps back which I removed with the famous debloater batch without deleting my data?
I read that there is a nice samsung app Drive Link which I want to try on my SGS3.
Thanks

The easiest way is to reflash the rom you are on without a wipe (exept cache and dalvik cache wipe), you will not loose data and your apps are back
Next time make a nandroid backup before you debloat so you can restore that config.

nandroid can be with titanium backup?
Also I am on the stock rom so maybe I can do something with kies?

nandroid + flashing/restoring across roms

I'm having a little trouble understanding nandroid vs. other forms of backup and would appreciate some clarification. I'm running CM nightly on my Fido (Canada) G4. I took a nandroid as well as titanium backup of the factory stock image before I flashed CM.
A poster in the last thread I made suggested if I wanted to restore to stock, I could simply restore the nandroid, but I've also seen people say you shouldn't use nandroid to go across ROMs. My understanding is that nandroid is like having a filesystem backup, which would obviously not react well if you restored it over a new operating system (e.g. two different versions of windows). Or is nandroid more like say Acronis, which takes an entire disk image and overwrites everything?
Other misc questions:
- If I do restore via nandroid, do I need to wipe all data / cache / system data before or after the restore?
- I assume I can use titanium to restore SMS + all non-system apps across ROMs, which would save a lot of time.
- If I'm going from one CM nightly to another, would titanium work for system apps (e.g. all my settings, or contacts, etc)
- If I want to flash a new CM nightly, do I need to follow the entire wipe procedure just as if it were going from one ROM to a completely different one?
Thanks!

always make a nandroid in recovery. i recommend keeping it on your micro sd card. in the event you need to return your device to it's previously functioning state, restore the nandroid in recovery. if you are running an aosp rom and your nandroid is touchwiz, wipe data, cache & dalvik before restoring the nandroid. if the backup is on your micro sd then feel free to wipe system as well.
if you want to flash a nightly or update to a rom you are currently running, simply wipe cache and dalvik then flash the update, gapps and any custom kernel that you may be running.
i cannot answer your titanium backup questions because i do not use that program

yes, that's about what I have. ok, thank you for the clarification of what to wipe! that's good to know.
re flashing a nightly/update: using your method should preserve system data yes? so no need to reinstall all apps or system data?
and thanks, I'll hold out hope that someone with titanium expertise will be able to answer that one

yes, system/user data will remain. understand, however, that if you perform one of these dirty flashes and you have a problem with the functionality of the ROM, you'll need to do a full wipe and flash to see if this clears the issue before you report the problem in the development thread.

Your right on both titanium questions.. However its not recommended to restore system apps you backed up on a aokp/aosp ROM to a touchwiz ROM and the other way around... Other than that like I said your fine

[Q] App Restore Issue

Quick background:
I was running stock Android 4.2.1 with a custom kernel & recovery (TWRP) and decided to install CM's latest rom. I forgot to make a backup before installing the new rom and, because I didn't want to lose all of my app data, I did not do a factory reset after installing the CM rom. This caused me to end up in a broken state with Android being stuck at the boot animation. To prevent myself from breaking anything else, I made a backup of this broken state using TWRP. I then proceeded to factory reset which got Android working again.
Question:
I have some app data (read: game saves) in the broken TWRP backup that I would like to recover. Is there a way to pull app data from the TWRP backup that I can use to restore the app using Titanium, TWRP, or something else?
Thanks in advance!

Thanks for the reply! I just tried doing that and the backup is detected, but no apps/app data show up. The list is blank.
Is there anything else I should try or is my data just gone?

Was the backup compressed?
