[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] After flashing ROM is it safe to restore everything using Titanium/MyBackup?

Hi all.
Sorry for a noob question.
I wonder about the correct restore procedure after flashing new ROMs...
Is it safe to restore everything (thinking of apps+data, system settings, desktop etc) using either Titanium or MyBackup? Or are there some burried negatives which should be paid attention to?
Thx.

If you're flashing a different ROM than before then you probably shouldn't recover the system data, just apps and user data

Better restore just apps, NOT data, these can make you get AOS Bug..

OK, but what about for example setting up the desktop?
Setting up the desktop takes time every time you flash a new ROM. Is there a workaround...?

I never heard of AOS bug (might be a device-specific one & not related to the devices I have), but what would be the point of backing up your data if there was no way to restore it? It is perfectly OK to restore your apps and their data. It's also OK to restore system data if you're not switching ROMs.
I personally never had any problems migrating my apps + data back and forth between Froyo and Gingerbread ROMs.

After flashing between multiple ROMs yesterday, restoring all app+data, I never noticed any problems. Any search I do for an AOS bug comes back showing it caused by 2.3.3 or 2.3.4. So I imagine that if you're flashing ROMs and restoring on Froyo or below you won't have an issue.

All right then... I will go with that it is safe to restore - at least if not switching ROMs... I think it will end up with some testing
Thx

in Regard to recovery and backup

I'm currently on stock rom with it rooted. I wanted to know if i do a back-up of a fresh install of the stock rom and I start to delete files off my phone. If I happen to delete the wrong file, can I restore with the back-up, will those delete files be there again?

If you have a custom recovery installed that supports backups then create a backup with it and delete whatever you are trying to. If **** gets bad then just use the recovery option to restore and you should be back to where you started

Did you do a Nandroid backup, through CWM, or a Titanium type backup ?
A nandroid one will restore the phone to the point in time of the backup. Any changes since it will be lost during restore.
Titanium, or similar, will allow a finer granuality of files/apps/data..
If you play at swapping ROMs and want to revert a nandroid backup is a MUST.

Kernel backup?
This may be a strange question. I just got a T Mobile Sensation yesterday and already rooted, s-off, and did a Nandroid Backup. I previously had a Samsung Captivate and flashed it all the time. This is my second Android device and first HTC device, on the Captivate Nandroid only backed up the ROM without touching the kernel making flashing back and forth between ROMS a PITA. Is the same true with HTC Sensation, will Nandroid also backup the kernel?
Please don't flame me, I used search and found this thread so I am attempting to find answers without starting new threads on topics already discussed.
Thanks.

Does that mean that with a Vodafone NL branded phone (no RUU available for download at this moment), I can S-Off, Root and use nandroid backup to create an image I can always return to?
I want to get rid of the VF crapware as well as the quicker updates. In other words: a stock HTC (not vodafone) ROM.
In case of a hardware defect (unrelated to flashing other ROMs*), I want to be able to get back to VF branded, so the guys at HTC (who know what S/N belongs to Vodafone) won't see anything weird.
Thanks
*: If I mess up, I am willing to pay for it. But if it's unrelated, I don't want HTC to be able to start whining about software changes by me.

[Q] Superwipe and titanium backup and new ROM question

I'm about to install Android Revolution HD™ 3.x XE but my question is I'd like to back up my phone and apps with titanium backup and restore my phone after installing the ROM
Now I know I need to use superwipe but buy restoring everything after am I defeating the purpose of using superwipe?
I dont want to be restoring old files I may not need or could cause problems
Thanks In advance

Although I don't have a firm answer to your question, I would advise you against doing a full restore (system data and everything). I've had numerous problems such as my lock screen PIN code changing after a reboot (preventing me from logging into the phone).

I backed up using Titanium then used superwipe, after I had flashed the rom and restarted the phone all my apps automatically reinstalled. I am a noob so I am not sure how or why this would have happened. I would add that everything went very smoothly for me and the phone is running very well, absolutely no problems and I am very new to this rooting game. This website and the developers that are on it are both fantastic, a big well done to all concerned.

I just flashed arhd and restored "all apps with data" with titanium backup. everything seems to be running smoothly

Thanks for the replys, I'll probably Flash the new ROM at the weekend

Mine did the same thing. They reinstalled (most of them anyway) because google kept a record of what I had loaded from the market. The only thing is because they were reinstalled automatically the market doesn't give me the option of removing them. Is yours the same?
On a side note a while ago when I first used LeeDroids rom I used titanium backup to reinstall my apps and data. When picked my phone up the next morning (it was plugged in all night) it was red hot where something was loading the cpu up. I reinstalled the whole thing a couple more times before I realised it was either an app or the process or reinstalling them on a different rom with Titanium that was causing the load. Now I use mybackup pro and just keep my data and install the apps separately.

Just dont restore your system data as it may cause problem, only back up and restore user Apps...
Contact and SMS can be easily backed up via People and Message options.

[Q] Can I flash 2.3.5 with CWM without data loss?

For some reason I find mixed answers to this simple question:
I have CWMv4.0.1.4, I rooted with Ace Hack Kit months ago. I am currently running 2.3.3. I would like to update to a ROM with 2.3.5, is there any way to do this without data loss?
Some people seem to say if you use CWM update from SD card option, you don't lose data, other people emphatically answer YES YOU ALWAYS LOSE DATA ALWAYS. Which is it?
Thanks

The sdcard data will remain intact...the phone data can be kept but it is always best to do a full wipe to avoid bootloops or malfunctioning.
Just make a backup of your apps with titanium backup and restore it afterwards...also make a nandroid backup of your current rom just in case...

I also use SMS Backup+ to back up all my text messages to my Gmail account to be restored after I change ROMs.
