[Q] Galaxy S2 i9100 Official Android 4.1.2 Firmware - Galaxy S II Q&A, Help & Troubleshooting

Does any one have the download link for Android 4.1.2 Jelly Bean (i9100) Samsung Official Firmware? I flashed a custom rom to my Galaxy s2 without creating a firmware backup so I cannot revert or downgrade to original rom. So I was wondering if I could download official 4.1.2 firmware then I can flash it. One more thing pls: A friend of mine own a galaxy s2 i9100 and it has the same version of firmware that I am looking for, so can I make a backup of its firmware and flash it to my s2 or copy its firmware as a zip file or something.

Sammobile is all you need looking for your apropiate carrier of course.

Samobile requires premium account

No it does not. You only have to register, for free, in order to DL firmwares. Nothing premium required. Stop spreading nonsense.
Also, next parrot who posts 'Go to Samfirmware' to this thread dies. Once was enough, 3 times is ridiculous. What the hell is wrong with you people ?

I thought it was premium ..
Thank u man

[Q] Updating With Another Country's Firmware

Hello, please, is it possible to download another country's official firmware from Sammobile and install on my Galaxy SII? Will I also be able to get official updates (like jelly bean 4.1.2) and install them in my country whenever updates are available in that country since i'm using that country's firmware?
I am still stocked with Android 2.3.5 and I really need to upgrade it to Android 4.0.4.
If it is possible to do so, please recommend a country from sammobile.com that I should download and install the firmware (preferably android 4.0.4) to my Galaxy SII. Thanks a lot.

try Kies for an update. Almost all countries have been upgraded to 4.0.3. and please don't install 4.0.4 it has got a super brickbug.
First of all, I really appreciate your quick response and advice.
When I used to try and update via Kies it tells me I'm using the latest update + I live in Nigeria and the latest update for Galaxy SII in Nigeria on Sammobile is android 2.3.5.
I recently upgraded my phone to the unofficial Galaxy SII's jelly bean, after I noticed a few irritating bugs, I decided to switch back to my stock 2.3.5. But there is one problem though, the baseband version is still I9100XXLS6 (the unofficial jelly bean baseband version), therefore, my Kies application cannot recognise it, it always says " Your device's current firmware version is not supported to update firmware via Kies" when I connect it to Kies. How can I change it back to the original baseband version to be able to use Kies?
There are pictures to confirm this. Thanks

those few irritating bugs have been fixed by different developers, you can try a rom based on XXLSJ, which have these bugs fixed. Or you can even try Siyah Kernel v6 http://www.gokhanmoral.com/
How did you reverted back to Gingerbread. The correct is, Flash Official firmware download from www.sammobile.com with ODIN.
I reverted back to gingerbread using the backup I made previously before updating to the unofficial jelly bean. The backup still has the correct baseband, but I don't know why the unofficial jelly bean baseband version is still here. Do you think downloading and installing that from Sammobile will solve the baseband version issue? Thanks

yes, flashing with ODIN will fix it, but it will wipe your current OS. Or else just flash your pervious modem with ODIN or through CWM.
Ok. Is it advisable to download another country's firmware? For instance one of India's Android 4.0.3 since you said 4.0.4 has issues that might cause break. Thanks

to fix baseband issue, just flash the modem which you had previously.
yes you can install 4.0.3 from any country. Just change the CSC with https://play.google.com/store/apps/details?id=com.manniakk.cscselector&hl=en
Alright, thanks for your help. I really appreciate.

Hi, I downloaded the official Android 2.3.5 (I9100XWKJ1_I9100OJVKJ1_I9100XXKI4_HOME.tar.md5 and SS_DL.dll) from Sammobile. It's quite different from the usual CODE, CSC and MODEM files from other firmwares. Please, how can i install this on my Galaxy SII using Odin? I've searched the web for that but all I saw was how to install the leaked version of Android 2.3.5.
NB: I downloaded that of Nigeria. Thanks

Sorry, I forgot to ask if I must be rooted before installing the official Android 2.3.5. Thanks

No, ODIN doesn't require your phone to rooted.

Thanks, but after successfully installing android 2.3.5, will I need to inter into recovery mode to delete all user data and wipe cache partition in wipe data/factory reset option and finally reboot it?

Mobile odin does the trick without much of a problem.

Yes. You will have to do a factory reset from the recovery, otherwise you will get stuck on the Samsung logo.

[Q] help? I can't find out my stock firmware

Hello I own a Samsung galaxy SIII GT i9300 running nightly build PAC man ROM 4.4.4. I deleted my stock backup on cwm thinking that I wouldn't need it but I'm getting a upgrade to the LTE version (GT i9305) now and I can't find out which model I am for stock firmware to sell this on, it doesn't say in settings and dialer doesn't work, and I need stock to sell this on. Is there a working ROM on all international's? I'm a noob at this so sorry if this is already answered or its a stupid question
EDIT:I know how to go to stock but don't know which firmware is right. also build number in settings says PAC man ROM nightly then numbers..
Thanks in advance!

Follow the guide in sticky thread, download the latest stock firmware for your country at sammobile.com
It doesn't matter what version your original firmware was, just make sure it is for the i9300.
Everyone says it does but okay thanks if it works
