So, let’s proceed and see on what are the pre requisites which you will have to follow before we proceed for the procedure to update the device along with the things which are now improved in this update with the instructions to update the device.

Do i need to Root my Phone before i update with this firmware?

The answer is “NO” as rooting is different from the firmware update. Rooting basically opens up the device with which you can even access the system level files which cannot be done in a non-rooted phone. This firmware update doesn’t require you to root your phone before you proceed for the firmware update. Another thing is that if you have already rooted your phone before then after applying this firmware the root access will be revoked and then again you will have to root your device to get the root access.

Rooting is not the one which is same as the Updating the firmware as both are totally different things. The firmware which we will be seeing is the Stock Beta ROM and are the leaks for the Official ROMs and not like the ones like Cyanogen or other Private ROMs for Galaxy S 4G.

    2.3.4 just google it I think it led me to xda developers site forum. I know you use odin and it comes with some voodoo lag fix thing that allows your phone to run faster than before. My phones benchmark reached around 1950 faster than nexus s.You can also root it too. Neal is great help but he makes mistakes sometimes, and he doesn’t realize it or it takes a while. I learned a lot from Neal but at the same time his firmwares have a lot of bugs in it. As for the wifi its the same for all 2.3.4 versions. you may notice 2 or 1 bars but its still same performance. Wiifii has many variables to it so you cant really complain about bar or signal strength, its just inaccurate.

    Hey Guys,
    Neal has been very helpful in getting us slackers updates for Android. Cut him some slack. Myself and many others have been able to learn a lot through Neal. Before picking up on him just know that Samsung Support has been nothing to Zero to help with updates, specially their Kies Software which normally works only on specific hardware’s. Neal has also been warning us that if we don’t follow the procedure we can end up bricking the phone, so Read the Instructions carefully and do it accordingly.

    Neal, You Rock.

          The update will work, but 2.3.3 has several bugs (battery drainage, MAJOR wifi issues). I don’t recommend flashing this update.
