Updating to new roms help - Please :)

Hey, urm new to the rooting business so please bare with my newbness. (i have tried searching)
Can someone quickly run me through updating a rom..
i.e Cyans just released an update, i understand i need to download and flash. But do i need to wipe before flashing? do i need to then re-flash my theme after flashing the new rom? So, does flashing an updated rom loose you all your data?
Thanks, love you guys.

If you're going from one Google based ROM (Cyanogen, JF) then you shouldn't need to wipe. If it's a HTC based ROM, then you would need to wipe.
So go ahead and flash, you shouldn't have any problems. If you find that you get stuck in a bootloop, just boot in to recovery then wipe and reflash.
If you dont have apps2sd and you wipe, you will loose them. If they're on your ext partition they will remain there.

How to upgrade rom after I applied a theme?

I don't really understand the way themes work. Do they just replaced some of the resource files? Or do they replaced some of the apks? Then How do I cleanly remove a theme? Just flash the same version of ROM back? Won't there be some files only belong to the theme itself still left in the phone?
And what will happen when I try to upgrade the Rom with a theme installed? Will it roll back to the original theme, as all the resource replaced with the new Rom? And if I still want to use this theme, just flash one with the new version?
I am just confused, will themes add files not belong to the rom itself, then just upgrade or reflash without a wipe might not be able to clean the theme. But a wipe is the last thing I am gonna do.
Right now, I am using CM 4.01 with Teds Hero Theme, and I really want to upgrade to CM 4.02, but these questions confused me for a long time, I just need a positive answer, then I can flash and move on.
Thanks

A theme has modified images and files of the rom. when you flash a theme it writes over the original files with the edited ones. you should be ok with flashing cm 4.0.2 then flashing the 4.0.2 version of your theme.
If you are really curious what all a theme changes just open up your theme and look at what files are in it.
plain jane answer to your question.
make a nandroid backup (that way if something does go wrong you have a stable version to go back to if you are not ready to wipe to fix it)
flash cm 4.0.2
flash 4.0.2 version of theme.
if nothing goes wrong then you are good

Thanks for the reply, I'm going to give it a try~

I rooted my phone, now what?

I've seen some pretty cool mods of the g1 out there, but how do I do it? For example how do I change my home screen, how do I tether, and what are the best roms? And if I do change the rom, will i have to root again?
Thank You

Cyan recovery 1.4
Cyan ROM 4.0.4
Nandroid Backup
AFTER all of that you can install a theme in the theme forum but make sure it is made for Cyan 4.0.4 and if you have problems do a restore using nandroid.
If you want specific instructions on each of these then look through the guides.
You will find a link for tethering in the cyan thread.
DO NOT skip the nandroid backup step.

Cyan? Is that a rom? Will I need to root my phone again to add that? I'm running jf 1.5 DP, if that helps...

First, give yourself a clap on the back, you did better than most
No you will not have to root again since by rooting you are turning your security off, the only way to unroot is to go back to using a stock provider build
Next a rom is a custom android build
The name rom sticks with us from our win mobile days
Yes cyanogen is the name of the dev who self named is rom also

Backing up everything and installing nightly builds

Hi I have just rooted my Legend and installed Cyanogen mod and its all running lovely.... I notice that the nightly builds come out quite regularly.
My question is this....
What is the best way to install the new ROM?
What is the easiest way to get all my settings/ installed apps back? Is there a nice and easy way of backing up everything so that I can install the new ROM and then reinstate everything?
Thanks in advance for any useful info.

Hi ,
One software for all : Rom Manager
With it you can :
backup & restore all your phone (from app or from recovery menu in nandroid area)
It also allow you to download and install other ROM like nightly build
Bye

Not sure if that is what the question meant? I thought they wanted to know how to reload all apps and settings on the new rom, not just how to recover back to the old rom.
I thought titanium backup would be the go, but I myself am still getting the hang of this whole rom flashing thing.
Sent from my Legend using XDA App

If it is just for restoring installed apps, then Titanium Backup would be the best way for me.

[Q] custom rom after applying the "easily update to 5.7.893 and keep webtop"

[Q] custom rom after applying the "easily update to 5.7.893 and keep webtop"
Hey guys new to the bionic and have already done lots of flashing and changing to it. I read the easily update thread so I reverted back to stock using the For3v3r root and applied the update and the webtop mod. After searching through the entire thread all pages no one asked or said anything about whether or not that mod will work if you flash a custom rom.
So my question is...Can I flash a custom rom after and it still work? I specifically like liberty so any help would be fantastic.
Thanks in advanced and I promise I searched and searched for this answer. Please help

I dont really know what you are asking. If you are asking if you can install a custom ROM after updating to 5.7.893, then I would say yes. If you are asking if you had a custom ROM on there first and then tried to upgrade, I would say, yes that should work too, so I guess the answer is "yes".

Thank you for your response. I guess to be more clear is if I am on the stock rom with this webtop mod applied can I go ahead and flash a custom rom without loosing the ability to have the webtop mod?

Generally any restrictions regarding mods and custom ROMs are contained in the post for the ROM or mod. The 5.7.xxx update is a system update. Think of it as firmware....the under layer. It may come in a Stock package, but if you Flash or mod in any way, you would be impacting only that stock package.....unless the OP posts in the thread.
Many people on other devices, may revert to Stock implementations....to do the OTA....then continue with other flashes like before. Things that are flashed, kernel, baseband, system, radio etc.....all work together with the hardware to deliver your Bionic experience.

That actually makes a lot of sense. I can obviously follow instructions to flash especially when the devs make one click roots and other tools to make it easy for noobs like me, but what you just said made my understanding much better.
Thanks again.

would restoring a nandroid from a 5.893 system be a bad idea?

I actually updated mine with forever root to 5.7.893 then flashed Liberty 1.0 ROM on my phone and its worked great so the answer is definitely yes.
