if you still have stock ics/jellybean extract the md5 ,you can find the modem.bin there and flash it using odin.

start Odin.
-Select "phone" and fetch the modem.bin file.
-Only thing checked should be "Auto Reboot"
-Put phone in download mode
-Plug in USB
-hit Start
Let it reboot

Guys, I recently have a screen orientation problem with my S2. When I enable the auto rotation, nothing rotates. In camera, the rotation went crazy. Tried several apps to fix it but failed. Any suggestion on how to fix this? I recently update my S2 to france 4.1.2.

Hi guys, i want to reformat (factory reset) my wife's galaxy S2 as the OS is now very slow because for many worms i think. I found the steps after googling.
Just a question:

1) Will factory reset remove all my saved pictures / videos?
2) will it revert the OS version? Coz I already upgraded it to ICS.

Hope you guys can answer! Thanks in advace...

Unless u tick format USB storage, it won't format ur pics ans vids.
Ur ps version is permanent ,factory reset won't change it

Thanks! really appreciate it! But i think i'll just backup my documents in case something happen

I will format using the below steps:

it's good to backup ur documents before doing anything to the phone ^^ i always back up everything before flashing new rom.

good luck on the factory reset bro!

my Battery is working fine with 2-3 hours of screen on.
but i'm hoping for more. looking for 2000mah battery but no one selling.

so i decided to check ebay. so amazed at the results i found. they are all very cheap. 2,5,7 usd (about rm6,15,21) with free shipping. one of them even boast 2450mah


but then my common sense is tingling, something is weird, and i googled review about them.
thank goodness s2 was once a famous model, and someone did a great review on these batteries.
http://translate.google.com/translate?hl=r...ah-2430mah.html
(worth looking)

apparently, based on this reviewer battery test between the 3500mah, 2450mah,1800mah and stock 1650mah
3500 mAh (actual capacity of about 2300-2450 mAh) - 9:00 40 minutes;
2430 mAh (actual capacity of about 1000-1250 mAh) - 5:00 20 minutes;
1800 mAh (actual capacity of about 1300-1450 mAh) - 6 hours 22 minutes;
1650 mAh (standard, the actual capacity of about 1600-1650 mAh) - 7:00 43 minutes;

So in short, the 2430 is FAKE, the 1800 one also fake.
even if buy the 3500 with that extra bulk, dont really double the capacity, sigh....

thanks for the info bro. imo, just buy the 2000mAh one la. im using it now and serves me good.

I just swap my batteries if i need it as i hv 4pcs spare...

Hello guys,
How do I revert back to 4.0.4 from 4.1.2?

My battery drain as fast as niagara fall and I'm never happy owning this phone because of its battery life.

610 hours of standby time is bullshit tho

Anyway, any idea how to revert back to 4.0.4 ICS?
Mine is GT-9100G, SME set.

haah true. i have 2 batteries. so quite easy la if wanna change.

610 hours is almost a month o.o even my old nokia cannot stand that long =O

to revert back, simply choose the correct 4.0.4 firmware and flash back thru odin. but do not use CWM to wipe. u will brick it. wipe after u revert back to 4.0.4.

good luck!

Thx bro..

But where to find the correct firmware?

samfirmware.com

samfirmware.com

Done with odin.. it shows me big green "PASS", but my phone stuck at boot. How?

I have 2 battery too. But I prefer that one battery can last me from morning till night.

My phone stuck at boot screen after update via Odin.
Any help?

Reflash rom again using Odin.
Hope U can still enter download mode.

clear dalvic cache

edit : lol there is no dalvic cache in stock right..i forgot..
you can try kernel wipe then install back using odin.

Yes, it worked.
Thanks bro.

Hopefully battery life in 4.0.4 is much better than 4.1.2
