I sold my iPhone 4 today and bought a brand new nexus s. I'm not new to android though, I used to own a nexus one before iPhone 4.
My question is that I want to install custom roms on it, but I might want to restore it back to original factory settings in case I want to return it to best buy. How can I backup my phone so that best buy would take the phone back without questions?
I saw a thread to root the phone without unlocking the bootloader. Is that what I should do? Any help is appreciated!

Just root and do a nandroid backup. If you use rom manager to install the custom recovery you can just use it to so the backup.

Go to the Samsung nexus s android development section. Look for the thread that begins with Odin 1.81... bookmark that thread. That thread will help you flash completely back to stock. And always make sure you relock your bootloader.

The only advantage of not unlocking the bootloader is to avoid a full wipe of your internal storage such as pics, music etc. However custom roms or apps may have stability issues without an unlocked bootloader. No harm in unlocking the bootloader because you can always lock it again. Just make sure you back up any files you may want to keep.

I agree that the only advantage to not unlocking the bootloader is to avoid a full wipe and loss of all data.
I'm curious if you can point to an example of any current existing ROM that displays issues because the bootloader is locked... if so, I need to add that information to the non-unlock method instructions.
Sorry I don't. I was just quoting one of the root guides in here. But then again there's always that IF. Now that I think about it, unlocking the bootloader is to be able to install root and a custom recovery. If you can do that without unlocking the bootloader then you should still be golden. Don't see why a rom or app would be dependent on the bootloader. Sorry for the confusion.

Yeah, we've found no reason to HAVE-TO unlock it yet. Just to be clear, I wasn't challenging you, just looking for anything I might need to add to the guide on doing it without the unlock. I already have a caveat that it might be an issue for something, but don't know what something could be.
Anyways, if you're a fresh out of the box phone, no problems unlock method, since you have no data to lose in the wipe. For late-comers, the no unlock method spares them that data wipe. The beauty of it is that you can root and install titainium or other backup software without wiping the phone if you already have data on it, and then if needed you can always unlock it and re-root, and then restore your wiped data. Best of both worlds for some.
Pretty much exactly what happened to me Distorted loop, Very thankfull for that non wipe root method, definately saved my ass as i had a good play with the phone before getting it to a PC for backup/rooting.
I am going to swap my device for another tommorrow to confirm if my reboot issue is even remotely hardware related. So i will have 30 mins with no nexus s ...s'gonna kill me as i love this lil thing (even with my calling problems).
Looking forward to a nice stable nexus, and then i'll try out some of the mods and roms (still on stock for now)
i need some help im thinking of Unlocking the bootloader and rooting.But I heard this erases data.How or can I back up all apps and there data.
Plus after this could I unvoid the warrenty by going back to stock and re-locking the bootloader?
You can use Wug's Nexus Root Toolkit to perform an ADB backup without having rooted the device.
To answer your other question, yes you can relock the boot loader and return to the stock rom.

If it is only matter for the APPs. easy way is to use google play, under your account name. They are all saved (once you downloaded them the first time) for further back up one a single clic.
No a solution for data. but most of the time no real need for apps/data backup.
When I had 4.2.2 I rooted my nexus 7 without unlocking bootloader now after OTA updated to 4.3 I've lost root and I don't want to unlock bootloader to root and loose data. Is there any way to get rooted without unlocking bootloader or without loosing any data???

I am also looking for any updates about this root method.
any news?
I think it's pretty unlikely a 'motochopper' like exploit will be available any time soon.
Google, with Jellybean 4.3, have beefed up Androids security considerably, ostensibly to protect the device from exploits of the malicious kind. Whilst inconvenient for easy rooting, I think anything that enhances and improves security is most decidedly a very good thing indeed.
So, whilst I don't think a 'root-without-unlocking-the-bootloader' exploit is totally impossible under 4.3, I do consider it improbable.
And in any case, updating and rooting 4.3 from a locked bootloader condition (without loss of data) isn't technically difficult... it's just time consuming.
It took me about 2 hours or so, to go from a CyanogenMod 4.2.2 ROM/franco kernel combo to Jellybean 4.3 Factory Stock and rooted... with no loss of data. Using these steps...
1) Backed up all my apps (and app user data) with Titanium.
2) Copied the entire contents of my Nexus 7 (including my Titanium backups) to my PC, using ADB pull.
3) Unlocked the bootloader. (I was bootloader locked, rooted via motochopper).
4) Fastboot flashed Jellybean 4.3 Factory Stock.
5) Fastboot flashed TWRP.
6) Flashed Chainfires SU root updater.
7) Copied everything back to my Nexus 7 from my PC.
8) Restored my apps (and app user data) using Titanium.
(If you're already on Jellybean 4.3, you can skip step 4).
Besides, what else are going to spend a few hours doing on a rainy Saturday afternoon with nothing worth watching on TV? And such an exercise will confer several benefits...
1) It will hone your data husbandry skills (backing up data is always a good thing).
2) It will fine tune your knowledge and experience of fastboot and ADB.
3) It will root the device... and finally...
4) You will gain the satisfaction of your accomplishment.
OK... maybe I am trying to oversell it a little.
But my point is... you can either wait for some future putative exploit (that may never come) from some genius developer (who may not exist)... or you can bite the bullet, and do it the old fashioned way... today.
Anyway... just my thoughts.
Rgrds,
Ged.
Honestly if you are going to unlock/root it, use an app like helium(play store, free) to back up app data, and then move it to a computer, and then finally move it back, install helium again and restore. I did it.

Thanks for your advice I know the benefits of the standar rooting but you forget the benefits of being stock!!! The backup way of rooting an no loosing data is the only way but I have a plenty of time to wait for someone to make possible to make root without unlocking the bootloader. I don't use so much my nexus and the apps that wants root so I can wait, everything I use now after the update to 4.3 is free.
Thanks in advance for your answer!!!

Ok so my SGH-I337 S4 is rooted using Motochopper and is still stock ROM, just rooted. I did it so I could make Google Wallet work on AT&T, which was successful. Now AT&T has an OTA update that I want. So I will have to unroot. I already have the stock ROM download that I can flash via Odin to unroot. But what will happen to the apps I have installed that require root, like Titanium Backup, ROM manager, etc. Will they automatically be removed or just stop working? Also, has anyone had any experience with the Universal Unroot app? That would sure be easier. But my main question remains: what does Unrooting do to apps that are installed that require root privileges?
Sent from my SGH-I337 using Tapatalk 4
When you user Odin you'll have to do a factory reset or you'll get into a boot loop. So by by apps. Your tibu backup file will still be there, but just in case copy it to your pc before hand. The apps that require root will not work until you re-root.
Hi highly recommend you don't get the ota. Even though it's root able it's very dangerous to do so.
What I will say, if you want the update is to go here http://forum.xda-developers.com/showthread.php?p=43963746 and you will have the benefit of the OTA and not lose the root and custom recovery, and all the app will work! You will not upgrade the bootloader. Once you updated the bootloader is not coming back!

I don't understand why you get a boot loop. I once soft bricked a phone and used Odin to flash a md5.tar of a stock ROM. The phone rebooted and I saw my wallpaper and all my apps and data intact. I have seen threads on Unrooting that describe using Odin that way. They all said that doing a factory reset afterword is if you want to delete all your apps and data like if you sell your phone or just want it as it was out of the box

thats interesting. were you on stock when you soft bricked it?
many, many...many users commonly have to wipe data/factory reset after flashing stock via odin. sometimes they can get away with just a cache wipe. not often, though.
I had used (can't remember his name) Galaxy S3 Toolkit to root the phone. Interestingly, Root Checker said I was rooted, but Titanium Backup wouldn't install... It said I needed root access... Hmmm.... Later when I went to unroot using the same S3 Toolkit, I did something wrong. The phone would boot but stick at tiny little letters in the upper left of the screen that I *think* said recover. I messaged the developer of the Toolkit and he sent me a link to download the original AT&T stock ROM. He told me how to use Odin and check the PDA box. I did it and it fixed my phone.

thats why i asked if you were still on stock when you used odin. most users are not, which is ultimately what requires them to factory reset in recovery.
I wonder if universal unroot is trustworthy
Sent from my SGH-I337 using Tapatalk 4
All that would happen to your rooted apps is they wouldn't have root privileges anymore, which means they ultimately won't work as expected. I would recommend uninstalling them before you update. You may also be able to do a full unroot via SuperSU or one of the other superuser apps.
NOTE: Your phone may not update even after unrooting. You may have to do a factory reset first. I don't know why, I'm not a developer. I'm just speaking out of my own experience from the past.

You can flash the factory image but you'll lose all your data. Or you can use wugs toolkit and use flash back to stock option and it will do it for you but you still lose all data. Are you sure you want 4.3? 4.4 is smoother for me

So to be clear, even if the N10 is rooted, in order to go back from 4.4 to 4.3 one has to flash the factory image? Wiping the device and restoring a 4.3 Nandroid backup of a previous 4.3 ROM will not work?

Yes it will work but your progress since that nandroid is lost if you dont backup. You can also flash a 4.3 rom. Or mod the Factory image to not wipe your SD.

If 4.4 is more laggy for you than 4.3, you're doing something wrong.
Maybe just trying a factory reset of 4.4 might cure it.

My Nexus 10 is also more laggy on 4.4. Strange.
Is it laggy immediately after the factory reset or after you've set up your apps?

Yes it is laggy even after reset and reflashing the factory image with wugs toolkit. When the screen rotates, there is some stutter. I'm back on 4.3 and it's much better for me.
Thanks to abdel12345 for recommending wugs toolkit. It was an easy process
I installed via the factory image, and have no issues with 4.4. If anything, it's better.
Hi,
i go now also back to 4.3 because Simpsons is not playable on 4.4! It's soooo laggy. But only this Game.

Yep I've figured out that the resulting system when you do 4.3---OTA---4.4 is a slower system than if you do a stock flash install. I've also now unclicked the "backup and restore" to not carry over anything.
Prove it yourself, by all means... if you're going to flash down to 4.3, flash to 4.4 first, try it and then flash to 4.3 if its still laggy, but I betta 5cents you'll find it better. That one game - Simpsons - just install it and benchmark.
As I do not know what is the cause of this lag-from-upgrade, I now also don't click on the "backup and restore" to make mine as vanilla as possible. I've just now done this to my N4 also having found it better having done it on my N10 yesterday.
I been using WUGS NRT to do unlock (one time), flash+unroot, and root.
Am thinking of downgrading as well..

Anyone successfully bk to 4.3 w.o losing data?
Hi,
If you ever wondered if there was a way to restore stock without losing all your data, there's a way, which is not hard too... Just do the following:
Reboot in your custom recovery and then factory reset your device
Reboot system
Now download the Factory ROM and move it (the img files) to your adb/fastboot folder
Open a cmd there and do the following (remember to have the USB Debugging on)
Code:
adb reboot bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot reboot
Now wait for it to boot
Hope this helps you guys who want to downgrade to 4.3 and were afraid of losing your data (remember, the recovery still deletes your apps data, but you can backup it with an app like Titanium Backup).
I may write an script to do this soon... If you want you can wait for it (but it may be delayed up to this weekend).

That is useful to know but how is it any easier than simply copying to Wifi NAS or connecting external storage, copying it out and back in again? You'd be backing up anyways as a good techie. As you say it deletes everything bar data.
FYI if you did ever want to WRITE to NTFS volume then selinux mode changer app is what I use.

In my case this one is way easier, as I have almost 32GB used, and it takes a whole lot time to just backup, who says copying it back. I know it's good to always backup, however in some cases (like mine) it's a way easier method to do like I explained above.
This is just an alternative method I'd like to share, I actually used this many times already, due to soft bricks, then I can't simply plug a external hard drive on my recovery and it would take ages to backup my data via adb. This is the best unbrick method IMO, as you're installing fresh ROM without the need of formatting your data, and works as well with installing a new ROM .
Just my point of view hehe
