Welcome, umeraras, to AF!

I have moved this thread into the S2 forum, where others here with that phone may be better able to help you with this problem.
I am curious though, why do you want to downgrade it?

Thanks damewolf, i will check my post out on the right place then, i wonder downgrade it because i cant set password on this version (4.0.1 ) i do sell second hand Samsungs (wholesale) and i pay alot of money every month to some people they do downgrade for me, thats the reason.

I see. Well, hopefully someone will be able to talk you through the downgrade.
I wish I could be more help in that department, but I have never downgraded before, and I don't have that phone. Good Luck!

I understand why he would want to downgrade, i upgraded the s2 asap, but its actually worse, major glitchy, and i now have 4.1.2 thinking it would be better, it's not

1. First you will need to know your CSC code... see #1.1 of the Jelly Bean update - Dummies Guide. This explains how to find it.

2. You will then need to locate and download the stock Samsung firmware for Android 2.3.5, for your CSC code. This is explained in #1.7 of the Guide.

3. After backing everything up, you will need to flash the downloaded stock firmware via Odin. This is also explained in #1.7 and in the link which has a step-by-step guide and video on flashing firmware using Odin.

Whilst the title of the Guide I am referring you to states Jelly Bean, the actual processes are the same across all platforms, GB, ICS and JB.
