[Q] unroot/factory reset how every you call it! - Galaxy S II Q&A, Help & Troubleshooting

Hello,
I need to reset my phone back to factory settings, unroot or what ever you call it! How can i do this? I have got a usb jig so that i can reset the counter. Do i just download a stock rom and do it that way? Or do i plug it into kies and then restore it that way. I don't need to keep anything on the phone.
Thanks
Richard

Flash a complete stock Rom using odin. Latest for your region.

[Q] help please

Is there any way to reset the phone completely, to be just like when i got it the first time? I have flashed hell of a lot of roms on it and now i would like to wipe the slate clean. Is there any way to do it? I know about factory reset. Is it enough for wiping the slate clean.
I don't know much about the software behind the processes and i would like to know if the phone is being damaged everytime i flash a new rom? And would flashing the stock rom reset all the system files?
And i confess, I am a noob. I would be happy if someone can point me in the right direction.
From what I understand if you wipe data, cache and dalik cache in cwr and flash the stock rom it souls be to wen you got it if you want more peace of mind flash it to a earlier rom and do I upgrade using your phones software program to the latest software there is no damage done, the only thing (well on my type of phone atleast) it might have a glad counter which tells hoe many times its bin flashed but I think that can be reset with a USB jig

Flash your carrier's offical rom from here via ODIN. Wipe data first.

Then you can use usb jib(if original was GB) or Chainfire's Triange away from Market to reset the counter.

[Q] Galaxy S III Unrooting

Hello guys
How are you doing?
I hope every one is fine.
I have recently rooted my device which is Galaxy S III GT-I9300. After using the device, and discovering that Readers Hub is no more accessible, I decided to permanently unroot. I discovered that SuperSU app can unroot. And that's what I did.
But if you enter into download mode, you still find the device to be in custom mode, and that it uses custom firmware.
I read on the internet that restoring to my stock firmware using Odin can end up this vicious cylce (downloaded the kies version from Sammobile of my region). But I have two questions:
1- Is it real that restoring to a stock firmware can end up the "custom" problem? And is it still going to be able to update to JB?
2- Does restoring to the stock firmware wipe my data?
What do you suggest guys?
I heard of "Check Fus Downloader" that searches for stock firmwares that can be updated via Kies. Do I need it, or is it enough to use the Sammobile edition?
Any suggestions or draw backs?
Thank you very much.
I suggest you to use triangle away app to reset flash counter, do wipe / factory reset and flash official firmware via Odin (firmware you can find on www.sammobile.com). Then your sgs3 should be like out of a box..

Go to this thread and do all the things except for the restore from nandroid part. You don't need to flash the original firmware if you follow this method

Does resetting the flash counter change device status to normal?
I only reset the counter and now the Odin mode shows that the firmware is official, but my device status is still "Modified" in the settings.
Any idea?

I have a full video on Youtube showing how to un-root and get rid of the flash counter etc.
Search my friend
if i'm not mistaken, you now need to flash the official firmware through Odin, and you're good to go!
Thank you all for your valuable assistance.
Actually, the triangle away has not helped a lot. It is true that it has reset the counter, but the "Device status" in the "About phone -> Status" section of "Settings" app still shows it is modified. I flashed my "kies" firmware of Sammobile, yet still it shows "Modified".
Is there any way to get rid of this thing without wiping data? If the only solution is to wipe the data, is there any way to backup my app settings?
Thank you.
Cut and Paste
Revert to stock .
Download stock firmware .
Use Triangle Away to reset rom counter .
Delete root apps on phone .
Flash stock rom via Odin
Factory reset .

You have to wipe data/factory reset to make the status back to normal. Kies can backup some data and user apps. But the phone must be rooted to backup/restore user app data/settings.

As a matter of interest - could you check the status with and WITHOUT your micro sd card installed?
Sometimes the micro sd card can cause the status to show as 'modified' when it isn't really so .

Thank you all for your assistance!
Actually, removing the external SD did not fix the problem!
Well, I reset the flash counter using "Triangle Away", wiped my data to factory state then flashed an official Kies ROM. The status is now "Normal".

Going back to my stock ROM and kernel

Hi guys, i'm going to sell my galaxy s2 and the buyer want it all stock. I'm using the cm10 ROM on it. I've already downloaded the factory stock firmware on sammobile.com. Until there everything was ok, but now I'm not sure about the way to flash the stock firmware. Should I flash it by clockworkmod, as the customs Roms I've flashed before? Or should I flash it by Odin, like an unrooted phone?
Since now, thanks a lot for your help

Flash it via Odin as PDA
Then wipe all in recovery

when doing this, will the yellow triangle go away, phone get unrooted, and flash counter reset to 0?
cus im sure the buyer would want any avaliable warranty back aswell.
It would probably be good to reset counter before flashing, maybe with Triangleaway. Once i flashed original rom over custom with MobileOdin. Everything went well.

No, to reset counter and remove triangle you can do it either with a usb jig or by downloading chainfire app "triangle away" (Search it on the play store")

When u're flashing samsung stocks it'll does full wipe include rom itself, kernel, root, user data & caches then turn all to factory value. So don't even too worries about all u said above. But it worth to use stock 4.0.3 & avoid stock 4.0.4 in case to avoid emmc superbrick bug if u still doubt about advancing..

If you flash a "samsung official rom" it will take the triangle away but it does not reset the counter.
I have flashed CM9 CM10 and 2.3 stock , 4.0 stock a few times and my count is at 7, each time i flash stock the triangle goes away but the counter keeps counting.

Odin failed cant call out/in.

I recently tried converting back to stock firmware(xdlj4). Did it many time but this time Odin failed and I didnt know what to do. So I turned off Odin and rebooted back my phone. And got a message saying my firmware has failed and download via kies. Well I didn't and I just rebooted into download mode and tried flashing it again. It was successful but now I when I try to call out or have some one call me. I cant hear anything in the speakers or on speaker phone. Any help would be appreciated. Thanks

First of all when you use odin you need to have everything that is related to kies turned off.So before you try to flash again via odin, go to process monitor, kill everything that has to do with kies and try again. You tried factory reset and nothing happened? Can u be more specific? I mean your speaker had that problem after the factory reset?Or you flashed again and then you found out the problem?
(Keep in mind that it might be a hardware problem.)

Reinstalling Entire Phone

Hi xda developers members,
I'm currently trying to reinstall my phone back to stock with just the stock files and nothing else, can anyone tell me how I would go about this? I just want the phone cleared of all apps and other files as I want a fresh start with it.
Galaxy is currently running Jellybean 4.1.1 rooted.
Thanks.
factory reset in recovery if you've not been flashing any custom roms/rooted etc...
EDIT - or just do a reset through the settings menu

Unfortunately the OS is rooted. Is that an issue?
EDIT: Thanks for the information, so if I reset the phone via Settings > Back Up or Reset > Factory Data Reset. This will wipe all the apps, files and the root off my phone and just leave me with the OS?
nope -
run triangle away first if you want to reset the counter
then flash a stock ROM firmware from sammobile.com - use ODIN to flash it.
then full wipe through recovery
should all be stock then....

I'm a bit of a newbie when it comes to all this stuff so bare with me on this!
1. Why would I want to reset the counter?
2. I don't mind the device being rooted, I just want all the files and apps gone, I wouldn't mind if it was just the OS and the rooted files. Would that be done if I did the Factory Data Reset?
Thanks.
Oh right, yeah, if you still want root just do a factory reset

Cheers mate, much appreciated. I've just done as you've said and it's worked, hooray!
Now one more question if I may. At the moment, when I go and check for an update, it says "Your device has been modified. Software updates are not available"
This is a pain, as I don't want to loose my root, but I want to be able to update I guess, anyway to bypass this?
Im afraid not. You can still update through kies I think, but youll lose root.
The choice is basically root or ota updates..
Easiest thing to do is flash any new firmwares using ODIN then reroot using CF Root..
Or use custom roms..

Fair enough, suppose we can't have it all!
So when the next Jellybean update comes out, I just download the firmware from SamMobile, and flash it via ODIN. Sounds easy enough!
Thanks for all the help mate, once again it's much appreciated. Enjoy your evening.
Yep, thats correct.
Cheers, and you!

There is a function in the Samsung Kies Called "Firmware Upgrade and Initialization" which is located in the Tools of the Samsung Kies 2.5.0.
Fill in the information it requires and follow the instructions.
It will repartition your phone and install the new pure firmware just like it is a new phone.
