Root Restoring apps into new roms - dangers or unintended consequences?

Hi,

Having rooted an Orange 2.2 Desire I am now using Supreme Desire 1.2. I like it but I have the bug and I am sure that I am going to experiment with other roms.

I am happy with Titanium backup, it is very straightforward. My questions are:

1. Is restoring an HTC app like the stock email one, and therefore gaining all of my settings etc, the same as restoring a third party market installed app? What I mean is will it just work or might it rely on other things that no longer exist in the new rom?

2. Is it just a case of trial and error?

3. Should I just sack-off all stock apps and work from market apps that I can fully restore into any new rom?

4. Am I just being a bit thick?

Cheers

4. - No, these things aren't obvious.

They aren't obvious because it's not clear to someone who's only used Sense ROMs what is HTC and what is Android. But as a rule of thumb you should assume that any HTC app cannot be restored. Always take a nandroid and a titanium backup before flashing a ROM. Only restore user apps. It almost certainly won't successfully restore HTC apps anyway. As your email is on a server, that's an easy one to handle - it's just a matter of getting used to an third party email app (or the inbuilt one) rather than the HTC one. But you should make sure you have SMS/MMS/Call logs backed up other than through Ti before flashing anything, because Ti treats these as system data which don't copy well between ROMs. MyBackup or SMS Backup+ are your friends here.

As usual, your first reference is SUroot's rooting faq, which can be found via the sticky post "all about rooting" in the root subforum (red link in my sig).
 
Thanks Hadron

Nice to hear that I'm not being silly. I thought it would cause issues.

I'm using SMS backup via Gmail and I'm using Gmail for all contact info. So simple to restore from there.

Need to find out which user apply are the most suitable for my needs then.

Incidentally, I restored wifi access points through Titanium and that's worked, so would the bluetooth pairings one work too?

Appreciate the prompt reply.
 
Can't be sure of BT pairings. I've restored these between different AOSP ROMs, but cannot guarantee they would restore between all ROMs. I expect that if WiFi APs work then these will too, but re-pairing is the safe option, and I'd certainly suggest nandroid before restoring such settings, and testing for subtle bugs afterwards.

But I want to temper the caution above. If you know what you are doing, and have backed-up first, and it's not known to be a problem (see the FAQs), then don't be afraid to try stuff. Think it through first, but if it makes sense then try it. That, ultimately, is the real difference between a "computer expert" and a "computer owner" - not knowledge so much as attitude.

(Be warned, I've been drinking tonight).
