Stock, official, Samsung Galaxy S2 firmware can be downloaded from the SamMobile Firmware Page, after registering, by entering either "i9100, i9100G, i900M, i9100T, i9100P" in the, "Search device here", box on the page followed by your CSC code, (i9100***), see #1.1.
That's the old, KD1, GB firmware.
As per #1.7...
The latest, unbranded, stock firmware for XEU is LSW.

Im tryng to update my samsung galaxy s2 to jelly bean 4.1.2 from gingerbread 2.3. Iv dwnloaded kies to laptop, once phne is connected to it kies says, "your devices current firmware version is not supported to update firmware via kies. " y does it say this and is ther a way to update to 4.1.2 if so hw?

Just like to say had a rock solid, only a few apps, non-rooted S2 I9100 running JB and upgraded via KIES, because it told me to and I didn't know any better. Battery life was toasted after the upgrade.
Factory reset failed to resolve. But using ODIN and all that pain and time worked. Now superb battery life and everything cool.
Listen to Ironass! Thanks.

I have personally used a number of the ICS ROM's, LPS, LP7, LP8, LPD, LPF, LPG and LPI, LPY and LPZ and the new Jelly Bean firmwares, LS8, LSD, LSE, LSJ, MS1, LSN, LSS and LSW and they are all stable and work well. So it's no good blaming the firmware itself I'm afraid.
As I said, this may seem a lot of hassle but the alternatives are:-
1. Put up with your phone the way that it is.
2. Take it to a Samsung Service Point and get them to re-flash it for you... in which case you will lose everything anyway.
3. Re-install your old firmware using Odin, which may not solve the problem anyway, and possibly lose everything.
The choice, as they say... is yours.![]()


Hi! I'm fairly new to android.
I purchased Galaxy S2 GT-i9100 a few days ago. The place I got it from did the v4.1.2 update for me, right after we opened the box. I'm thinking the phone must have been on v2.3. Anyway, I'm not sure how confident this staff member was with android... (he thought the phone already had Jelly Bean before we checked under Settings>About Device).
He used Odin to update the phone.
So I've been using the phone for a few days now and I'm noticing some annoyances...
Unable to lock phone - no lock screen appears.
Problem with my SIM - no service (no bars).
Charging the battery (hard to explain) - sometimes charging animation is distorted/pixelised and doesnt represent true battery percentage.
So as mentioned, I never had a chance to use the device at all before the Jelly Bean update, but currently, here is the version info:
Typing *#1234# into dialpad gives the following:
----------------------------------------------
PDA: I9100XWLSW
PHONE: I9100XXMS2
CSC: I9100XEULS5
Build Info: Thu May 16 09:42:01 KST 2013
----------------------------------------------
I'm thinking I might need to re-install Jelly Bean v4.1.2 and I'm unsure how to go about getting the official firmware that is compatible with my device in this current state. Kies tells me that that my current firmware does not support an update.
Any ideas/advice? Thank you!

I'm unsure how to differentiate between what CSC code my phone actually has, and what CSC code refers to the current version I am running.
Thanks!
