As you all know I own a Samsung Galaxy S 2, a Powerful Dual-Core Processor Android Phone. Few days back, I installed Android 4.0.3 ICS ( Ice Cream Sandwich) on my Phone. The ROM which I installed was not officially released by the company but was said to be the stock ICS ROM.
So I thought of getting my hands-on it. What I did, I installed Android 4.0.3 ICS using Odin and restarted my phone. Then I experienced the Android ICS interface and features. Sincerely I am impressed with the UI beauty but the problem which I experienced is of touch responsiveness. My touches on the phone was not responded instantly. So I made my mind of getting rid of it.
Next, In order to get rid of this Android 4.0. I installed Lightning ROM using Odin on my SGS II. My Phone got stucked in Booting Loop. What it was doing is restarting again and again. Whenever I try it to switch off using long pressing power off button, it restarts automatically. I was feeling very scared.
I tried to install the same ROM once again using Odin, I switched my phone to download mode using the Volume Up + Home Key + Power button combination, but the same problem persisted.
Then I thought of wiping the ROM contents using ClockWorkRecovery Mode, I entered into the recovery mode using the Volume Down + Home Key + Power Button key combination. I tried to wipe cache, data etc, I tried to mount system, data directory, but I was facing some errors can’t mount etc. My fear reached its height.
The last option/solution which came to my mind is installing the Stock ROM i.e. Android 2.3.3 or Android 2.3.x on my SGS II. So I went to samfirmware.com and searched for Android Gingerbread ROM and downloaded it.
I restarted my phone in Download mode and started Odin and specified all the required files. The installation process started and got finished within few minutes. The phone restarted automatically.
Thank god, it asked welcome to Android and opened the First-time setup wizard for configuring the device. I was very happy and feeling relaxed.
If you are facing the same issue, Then you follow the steps which I followed. In the next tutorial, I will write how you can get back to Stock ROM, if you are stucked in the infinite booting loop situation or you are fed up of custom ROMs.
