Hey everyone, new member here.
I need your help!
I need to restore a Samsung Galaxy SII back to its original stock ROM (back to the way it was out of the box).
A custom ROM was installed (not my doing) which began to stuff up the phone and I need to restore it back. This is for a friend of mine and they have no idea how to do it. I have some idea but I am lost. I have had a look around on the forums here and read through some tuts and found the firmware page but have NO IDEA which firmware I need and which ROM. Do I need firmware and a stock ROM? I know I need to hook the mobile up to the PC and run the stuff through a program.
Can someone here lend me a hand? I am not sure what ROM is on but I can check for you if you need me to have a look in the "about phone". There is also a file installed on the mobile called CWM which I have no idea what that is.
What I have to do:
1) Get rid of the yellow caution sign when the mobile boots up
2) Restore the entire mobile to original
Please be nice as I am new here and new to flashing roms and all that sort of stuff.
Thank you.
I would grab original firmware from sammobile the install with odin or mobile odin.
Many detailed guides about for both methods

Use triangle away to get rid of the triangle

Cool, I am downloading the firmware now.
I have also downloaded the new version of Odin.
Is the firmware the same as a ROM or are they 2 separate files I need and does it include the kernel?
Not sure if it has the stock kernel or not.
I just installed triangle away.
Do I use this app after I flash my mobile back to original ROM or before?
Before. You need root for it to work.

I have spent the fortnight since getting my s2 reading everything I can about roms, rooting etc and I cant say that there wasnt / isnt some confusion, but this is where I am as of now.
I want to start trying some other roms like CM7 or MIUI
To root I have kies installed for the drivers.
I have odin and also super one click
I have downloaded the stock kernel for my phone which is XWKI4 from the xda site. I have the very bottom one which is around 8mb. My phone is from CFW but I didnt download the 200mb plus CFW one ( not sure if I need to? ).
I am going to download any insecure kernel and use with odin and then use superone click. I am then going to put the stock secure kernel back on.
Then I planned to download clockwork rom manager from the app store and start to download and flash firmwares with that.
Am I on the right lines or miles away from where I need to be? Been an iphone user for 3+ years so android in itself is completely new to me.
Any advice or help or confirmation I look good to go would be very much appreciated indeed.
Thanks.
Easiest to flash a cf-root to get the phone rooted. Installs CWM also.

Do not install anything with Rom Manager. If you want to flash things do it with CWM recovery. Go here and get your phone rooted and follow the guide it gives you. Could not be more simple to do it

You have odin which is great. Just find the kernel that matches your current firmware and just flash away. This way you get cwm recovery and then you get the cwm manager apk which again is a must app to have. More explanation is better on the thread link i gave above
Many thanks all. Will check it out when I'm back home.

no problem. just press that thanks when you get there
I dont have a computer. is there a way to root without it? My firmware is 2.3.4 and its kernrl is ki2. Thanks
I saw a thread a while ago, I can't find it now so you're gonna need to search, but you just put an update.zip in your sd, flash it in stock recovery, and viola - you have CWM (be sure to download a rooted kernel). Good luck.
If anyone knows of the thread please post links

Zips flashed with e3 needs to be signed and I think siyah is signed unlike many other roms and kernels so flash siyah and reboot to recovery recovery to flash anything, if you want to keep you current rom, I think downloading superuser is enough

zaheedahmed,
Yes it works on ICS not GB Since devices come with GB then they'd have to use ODIN to flash ICS
Anyway thread closed since been asked over and over!
Use the search before posting there is even implementation when posting to see threads similar too............
Hey guys
Sorry for the noob question but I want to double check something before I accidentally brick my phone.
I rooted my phone and flashed the Resurrection Remix ICS 9.7 rom and have had a play with it for a few days and want to go back to stock.
It's using a custom kernel and obviously custom rom.
To flash it back to stock using Odin, how do I get a stock official ICS kernel for an official ICS rom (such as one that you download directly from the Samsung server using CheckFus)? Also does anyone know of a guide that specifies exactly how to do this?
Thanks
You can extract the kernel (zImage) from the rom tarball you download via Checkfus with any program that allows you to work with tars (IZarc, 7Zip, WinRar, etc). No guide necessary, easy as. Open the tar file with said program, find the zImage, extract it. Done.

Need ROM to roll back to
Just got a i9100 with 2.3.4:
PDA:I9100XWKH4
Phone/Baseband (modem): I9100XXKH3
CSC: I9100OXXKH2
I don't find this rom on the roms page, and I understand I need it to be on my PC ready to flash with Odin, in case by flash to 2.3.6 doesn't work out (that's the only way to roll back, right?)
Where can I find this rom?
Thanks!
Hi everybody,
I'm new at this forum and in the Android world and I have a few questions about the install process of the ICS CM9 on Galaxy tab 10.1 GT-P7500 3G.
1. If I want to backup my current ROM, do I have to be rooted to use ROM Manager to backup the ROM? And do I have to be rooted to restore that backup?
2. Can I UNROOT my device later? (The device belongs to my father's work and I don't want to take any chances with the warranty things.)
3. How to install the ICS CM9? I think I have all the files I need to so, I hust need the guide.
Thx for your help!! I really hope that I will get this thing going already!
Yes, you need to be rooted in order to install cwm through recovery and then make a backup (although you don't need rom manager. In order to flash ics you have to install pershoot's recovery with odin). You can unroot later, but you have to remove the recovery as well if you want your device to be covered by warranty for sure. So flash with odin a stock rom and you're ok BUT you may loose the data.
Listen, ics installation is tested and almost fool-proof. But bear in mind that a lot of things can/may go wrong and then you'll find yourself in a mess. Since that tablet doesn't belong to you, you should better leave it be, unless of course you have your father's consent and you have explained him all the risks involved.
It wouldn't be nice to find his tab messed up!

Thx for the answers, but my stock version is not in the site, trust me i searched. My ROM version is p7500jjkj1. Can you give me a link to that?
And if I back up my current ROM through ROM Manager, will I be able to restore my device from this backup? or do I have to download the stock version?

Try to Google it. It may come up. You can backup your device through cwm but I would also find the stock firmware if you are going to want it in the future.

OP... Why are you so hung up on ROM Manager???
Just root using the Odin method mentioned, once you've rooted and have CWM installed just do all of your backing up, restoring and flashing through it. ROM Manager is nice and all but it has its own set of issues and all. Read and learn about what you are about to do... You'll be surprised how easy it is and you'll run into alot less problems.
Please put the ROM Manager down and step away.

Hi guys...
I have a galaxy s3 and up to this point I've been pretty satisfied with the original firmware...
However, I'd like to try out some of custom made ones, but since there's a big update on the way, I want to be safe doing so...
What I mean is basically this:
Can I somehow backup my stock firmware, try out some custom builds and then get the OTA update when it's available?
I don't really care about guarantee, but I'd really like the option to get OTA updates from samsung in the future (if I for some reason want to do so).
I remember an old post, where someone talk about this, but I can't find it
Please help me
Most definitely. You can find stock builds here in this forum and simply flash using ODIN to get back to stock firmware when you want to. Be advised this does wipe your data so have a good backup of it before hand.

And then it would be as my phone never were flashed and OTA and other samsung only stuff would work?
You will have to use triangle away or something like that to reset your flash counter if you want to send your phone to repair and make it appear as you have never flashed before but unless you break your phone, don't bother. And yes the other Samsung stuff should probably work.

If you flash your phone with a custom ROM for instance Resurrection Remix or Cyanogenmod you'd not directly be able to restore a stock ROM.
You will have to find one http://androidfirmwares.net that's for your region and flash it through Odin. Then you'll be able to update OTA and KIES.

i had the same fear of loosing my data and stuff so you can wipe dalvik cache and cache partition and flash omega ROM for ur S3 and welcome to perfection.
Ps. Flash with Siyah Kernel for battery craziness! ! !

You mean restoring from a nandroid? Because I was able to restore ICS whilst using JB - I did it multiple times.

Agree the advise given was plain wrong .
Nandroid restore a backed up stock rom yes yes yes .
The only but is that the backed up rom is of course rooted .

Okay... now I'm even more confused
Let me see if I get this right?
One way to do it would be to:
1) Download tools and rom (odin, CM and drivers etc)
2) Flash new cool rom
3) Donwload original samsung rom
4) Flash old boring rom back to phone
5) Use tool to reset counter (optional)
Now, my phone would like as if I had never ever rooted and flashed my rom
Is that more or less correct?
