[Q] What happen if I flash new ROM?

Hi, I recently got my nexus S, I'm looking to flash MIUI ROM into my phone.
Will I lose all my contacts,txt msg, etc...?
If so, how do I back up and import them after flashing the new ROM?

Hey! Glad to hear you are going to flash a new rom, if you decide to flash a New rom over the rom you are using "WITHOUT" wiping or factory resetting then your contacts apps will be there when you turn on for your first time on the new rom, however that is your choice, it is recommended by developers to wipe/factory reset before flashing new rom but, again, thatisyour choice, so why not wiping/factory reset when you can download back up and restore apps that will back up those paid apps or those important contacts for free on the market and they will back up on ur sd card and to later restore aftera fresh new rom!! Hope ihelped.

Thanks for the quick response.
I guess I will back up my stuff first before flashing new ROM. By the way, I have not root my phone yet, are there any application that I could use to backup my data, or do I have to root my phone in order to backup my data.

Data like? Apps or your network settings? Mms? Didn't quite catch that? Well first of all you have to root your phone on order to flash new roms, when you root you get what is called a "recovery" on there there is this option where you can back up your current rom also called " nandroid backup" it saves contacts, apps, settings, and data! Idk if that's what you meant. But after a flashing a new rom just go back to recovery mode and then backup/restore then advaced restore then choose data. It should restore your data.

[Q] Flashing Roms and Backing Up Data

Hey guys,
I've been flashing Roms non-stop trying to find one that I like. The main problem I'm having with this is that I have to go back and redownload each app every time I flash a new rom.
I've heard people say that you should absolutely not use titanium back up, but they don't give reasons.
How do you guys do it? This is crazy...

Titanium backup is fine, just don't restore system data, ever. Restore MISSING apps with data and you'll be just fine.

What do you (personally) do after flashing ROM

I am curious to know what other people do to restore apps and associated data. Do you go to market and download all from "my apps" or do you restore from an app backup? Or is there a better way? Can you help a noob out?
Thanks

So you just restore app+data? That's what I did, just wasn't sure if there was a better way. And a big thank you, I love your ROM.

yes, just restore missing apps+data. thats all i do.

Sometimes restoring data will cause issues when you flash new roms and the apps might now work properly. I always just flash Apps and then take like 10 minutes to set all the apps up again to be safe after every flash.

restoring MISSING apps and data has NEVER been a problem with me. you dont even want to know how many devices i have transferred my TiBu folder to, and restoring MISSING apps and data has not caused ONE issue, as long as I didnt go crazy and NOT go through and verify i wasnt restoring something Touchwiz related on my Sense ROM, or AOSP on my Touchwiz...etc.

Well I am just glad to know that I am not doing something that will mess up my ROM. I was nervous enough flashing the first time.

I agree TIBU restore apps and app data and be done. Only a few times the app data isn't restored when going from sense, touchwiz to a CM based rom but never had other issues. Flash rom the. Restore apps and data fro. TIBU pro and walk away whole it restores.

I don't bother backing up anything besides my contacts. I restore those first, connect my necessary accounts, and change whatever settings I need/want changed. Then I reinstall my apps.

Well, I agree 100% with Zel and Pirateghost there....Titanium Backup and later restore missing apps and data. As good practice, usually make nandroid back ups just in case.
The first time you flash a new rom is inevitable to sweat as a pig thinking that you will have to go back to your Motorla V3 is something goes wrong....

I don't flash as often as I used to so I use a newly flashed Rom to only reinstall the apps I actually use often. If not ill have a bunch of them I just downloaded and I'm not gonna use.
Plus reinstalling the apps myself and not titanium gives me a fresh Rom feeling lol, yea I'm weird.

I use very few apps myself, anyway, so it only takes a few minutes to set back up after a reflash. Most of those apps, I keep pretty close to default regardless. I run pretty minimal, so it's almost more trouble to take the time to keep everything backed up and organized for my devices than it is to just reinstall the apps each time I flash.
The posts here have given me a bit more to think about as far as TIBU, though, so I might take a deeper look into it soon!

Personally after flashing a rom I cook a slab of Bacon then shower. I then tibu my apps and launcher settings. You can imagine how much grease I take in while we are testing a new rom before release.
I got your 10 char right here

Thank you Bacon-Pope, your comments are (as usual) greasy, crispy, and delicious. Remember Turkey Bacon is neither turkey nor bacon.

after flashing
first thing I do after flashing is check WiFi phone mobile data camera then worry any apps. but I do use titanium backup and never had a problem. maybe I'm the weird one?

Titanium backup pro is the only app I will use to backup/restore.

ROM Toolbox Pro has EVERYTHING you'll ever need as a root user, all packaged in one epic app.

how do you quickly restore after ROM install?

For those that are testing roms,how do you back up your installed apps/data to load to the new rom and get up and running quickly? I have 80+ apps that I really hate to have to reinstall or have progress reset every time I try a new rom. I have TB but have seen mixed reviews here on its results. Any suggestions or advice would be appreciated. I have already read the threads how to backup existing setup in case something goes wrong.

Make a CWM backup. Install new ROM, then go to Backup and Restore, go to advanced restore, then select the backup you made, and select restore data. That will bring back all of your apps/setting and such.

I apologize, I misunderstood your question......
I used CWM when I went from stock rooted 2.3.5 to stock rooted 2.3.6 to restore all my apps. I'd imagine there could be some issues if you used CWM in the same manner when going from stock rom to say RebelROM so for that I'd use MyBackup. I prefer it over TB any day. So use MB to make your backup of your apps (apk's and data) before flashing the new rom, flash the new rom and then once you get MB on your phone again use it to restore the apps, apk's first then data after all the apk's have been restored.
Sorry for the confusion

I use Rom Toolbox...it works quite well

I just tested a theory i had and it worked flawlessly. I just flash supercharged v5 and before i did i just wiped cache and dalvix and formatted system, i did not do a factory data reset. I then flashed the rom and everything went flawlessly. I still have all my apps and data from before the flash.

[Q] Restoring system apps from Titanium Backup on same ROM

I have a backup of all the user and system data on a CM10.1 nightly (3/16, not that it really matters) and was going to do a clean flash of the most recent nightly. Is it safe to restore the system data after flashing the ROM? I assume this is where all my ROM settings, homescreen layouts, etc. are stored. I've seen a lot of threads where people say not to restore the system data, but I wouldn't think that would be an issue going from one nightly to another on the same ROM.

You can restore system apps but not other system data as far as I know.
Sent from my SGH-I727 using xda premium

You can try it but I wouldn't recommend it. I've had luck with restoring only the system data that has the tibu icon, wifi, accounts,etc.
Sent from my SAMSUNG-SGH-I957 using xda app-developers app

Ahh that's a bummer. So do you guys just write down your settings and manually set them up again? There should be an easy way of restoring this stuff, at least the homescreen layouts/Trebuchet settings.

I've only ever restored the user data and that seems to work okay. I guess another question would be how often do you do a fresh flash? Unless I encounter problems, I usually just dirty flash.

I never understood why Titanium Backup didn't explain that better. The app rocks but they make it sound like a lazy man's restore tool lol

Oh, I thought it just meant not doing the wipe data/factory reset step when installing the ROM, though I do see your point that restoring data over a clean ROM would be essentially a dirty flash. What about when you're just restoring user data and not any system data?

Clean flash every time, or you're gonna be one of the dummies making stupid threads about why your apps fc, and blaming the Rom for your mistakes.
Yes dirty flashes work sometimes, but for noobs it causes problems.

Restoring the data for user apps via titanium backup is usually OK. I am yet to experience any issues doing so.
