Finally there is some great news for Samsung Galaxy S i900 owners looking for an easy and painless root method. Senior Member, TGA_Gunnman, at XDA Forums has released a one click rooting tool for Samsung Galaxy S which not only roots Android 2.1 Eclair and Android 2.2 Froyo, but also gives you a one click unroot option.
If you are planning to use this guide on Windows X86 or X64 then make sure to download Samsung drivers before embarking on the root process. This rooting application requires Dot Net Framework Version 4 to work.
I noticed from the start of having this phone that I could not put it into recovery/download mode. Ive tried every steps I found on the internet. (vol up+home+power), (vol down+home+power), vol up+vol down+power) etc.. So I rooted my sgs using the one click rooting software. It worked fine. So when I wanted to install the lag fix, I use the same one click root software but replaced the rooting file with the lag fix file. It also worked fine and my sgs was fast and snappy! But my intro samsung logo graphics was not visible anymore but there was sound, other than that everything worked fine. 2b1af7f3a8
