[Q] Reverting to Stock ROM - Galaxy S II Q&A, Help & Troubleshooting

Okay guys, I'm in real need of your help here, whether it's a proper answer or some sarcastic link to the correct thread.
I've been testing out roms all over, and different kernels, but now I want to revert back to stock so I can start afresh. Ideally I just want the stock rom. I'm happy running an unsigned (rooted) kernal, but I do want the stock rom.
I'm in the UK, and my phone wasn't branded with any carrier.
Someone, help!

1: get odin
2: get stock rom
3: flash using download mode.

Hi.
I have Odin, and have used it.
I have used download mode to install a rom.
What I can't find is a stock rom.

Few Questions

Hey,
I have recently flashed and installed a custom CM7 rom to my Galaxy 5 but i am not happy with the results and i wish to go back to Stock 2.2- i stupidly didnt create a backup, so can anyone point me in the right direction on how to get back to stock, i am completely new to this kind of stuff so please try and keep it simple!
Thanks
ok, what method did you use to flash this rom?
You may have to use a different way to flash back to 2.2.
This post : http://www.madteam.co/forum/development/samsung-galaxy-5(gt-i5500)-rom-archive/ : has all the roms for our phone, so if you scroll down, after the third black line, you will see Official Roms's.
Look under that and you will see different regions 2.2 roms.
If you need any help with the flashing, just ask here
Thanks a bunch.
I flashed my rom using Odin to install Clockworkmod v4 then installed CM7 vis Clockworkmod.
Il have a read of that thread now but im pretty new to this so i may need some help

[Q] ROM

Hi,
Can anybody tell me if i root my s2 (currently on KF3 firmware) with cf method and flash stock kernel,will i be able to install new ROMS like litening etc,how ?, and will i be able to come back to my stock firmware and kernel,and how ?
thanks in advance !
You can flash any Custom firmware anytime, without root. And you can go back to Stock firmware and kernel anytime.
Regards.
so if i root(by a method you earlier told me),can i also use any rom on that ?if yes then how and also can you please tell me how to come back to stock rom(before flashing with custom rom) state ?
You just need to add the .tar file of the Custom firmware in PDA section of Odin and flash, same for Stock ROM.
Regards.
you can root your phone as ihappy said but use the threads on the forums to find the stock kernels and roms that suit you. and i mean by what region you at. most of the custom roms come with root anyway so i would not worry about rooting. the thing is though whenever you do flash always make backup. first time i flashed i did not do backup and i was panicking on how to go back to stock.but thankfully the guys in this community are the best around and helped me out. hope my post helped in anyway

[Q] ICS Update - SGS 2 Rooted 6 months ago

Thanks for reading - I'm a noob.
I came here to learn about rooting devices over 6 months ago and decided to have a go at rooting my SGS 2 to remove the bloatware and speed it up a bit.
Performance has been great - I left the stock firmware because the OS/ROM was not a concern to me. I simply flashed the kernel with CF Root: CF-Root-SGS2_ZS_OZS_KF4-v4.0-CWM4.tar
Now I am led to understand I would need to flash back to my stock kernel to allow the OTA update for ICS - the only issue is I cannot find any available downloads for I9100TDVKF4 - Telstra's stock kernel.
Now I read somewhere a reply to a similar question was "just flash it with a new rom, I dont know why you want to go to stock" - Well I want to update to the official ICS. I was under the impression that would be available a long time ago and never was. I just want to....
Please can anyone help me to point out where I can find that kernel? perhaps there is a different kernel i could use?!
Is there any ICS firmware I would be able to download and flash to the ROM using Odin whilst keeping my phone rooted?
I found this place really helpful in how to root and now I just hope someone can help me get onto ICS!
Cheers
Is there any ICS firmware I would be able to download and flash to the ROM using Odin whilst keeping my phone rooted?
No only custom rooted firmware .
Try Checkfus for your stock firmware download and flash via Odin .
Dont confuse yourself with kernels without understanding .
ICS on Checkfus or Kies for your phone install otherwise wait until your provider releases .
or flash your original saved firmware that will overwrite root .

Thanks for taking the time to reply mate....
Dont confuse yourself with kernels without understanding - dont worry ive been trying not to but it seems thats the only thing i changed on my phone when i rooted it so i was lead to believe i needed to change that back...
My provider has just released new version of ICS but i cant actually install it once ive downloaded it over the air it only gets to 8% then reboots itself and i believe thats because the phone is rooted...
or flash your original saved firmware that will overwrite root - I dont know if i backed it up correctly on the guide i was using!!! The only thing i backed up was the apps using titanium backup so now i feel im stuck!
Use check fus down loader and get the official ics ROM.
It's under i9100t Australia/telestra
Problem solved.

[Q] Hey guys...A little confused...

i am new to this device but i am not new to xda. i just picked up this device recently and im coming from the huawei ideos x6 forum. i am very familiar with odin and know how to use it. i was reading on the root thread and found that i have to go back to jfd 2.1 with odin. in the root guide i downloaded odin but the stock files i need to put into odin to flash are not there. can anybody be so kind to point me where i can find them? i am wanting to go to jelly bean which i have now on my other device and would like to use this device as my daily driver instead of my other. is there an easier way to get where i need to go? my goal is to have the latest cwm recovery and be running a jelly bean rom. any suggestions on how you guys think i should get to the point where i need to be? and my device is currently unlocked. thanks guys and all suggestions and opinions are greatly appriciated.
Oh i forgot my current software details are;
Model number: SGH-T959
Firmware Version: 2.1-update1
Baseband Version:T959UVKA2
Kernel Version: 2.6.29
Build Number: ECLAIR.UVKA2
Yes you should to go back to stock then you can flash JB, it takes two flashes to successfully flash JB (first flash upgrades cwm). As for the files to revert to stock with Odin, you can find them here http://rootzwiki.com/topic/605-guid...nja-apps-everything/page__p__11106#entry11106 (they are located 8th post down if the link doesn't directly take you there). Note, after flashing to stock you will need the update.zip B (from the root/odin sticky) on your internal sd card which will give you cwm on stock , then you can flash JB (remember to flash twice). You can also find the stock JFD files in the bible thread , go herehttp://forum.xda-developers.com/showthread.php?t=1982728 and click ROMS, then click stock JFD at the bottom of the list. You may need to unlock your phone again after going to stock, if so go here http://www.google.com/url?sa=t&sour...lIDoBg&usg=AFQjCNGhnJw3ZNH4_1OmhoQ9kfkjeYaf5Q and download galaxy s unlock , to unlock your phone again.

Will my phone get locked if I install custom rom?

I am about to install a custom rom, but I was wondering if this will lock my phone in my country, because I have seen in other thread about how to flash back my stock rom to get my warranty back here: http://forum.xda-developers.com/showthread.php?t=2505436
And he listed a firmware for some specific countries(which mine isn't listed), why? Sorry I'm a noob on this subject.
