I have two questions. 1, does this install SU along with the root or will I have to do that separately? 2, whats the best method to unroot without factory reset?

Will the commands from the prompt put it in fastboot or is fastboot a driver in sdk? I think I need an android/windows functionality FAQ for dummies..

Yeah anytime you want to flash img files you just drag and drop it into sdk -> tools. But if you just shabby's one click it does everything for you.

Otherwise if you wanna root the long way, then yes you will have to manually unlock the phone, flash cmw, and through cmw flash super user.
The pros of doing it manually would be that you can make a backup of your phone without su installed and you may also be able to have a stock recovery, so unrooting would just be to restore your phone to that backup and just lock up your phone and bam done.

fastboot mode is when you turn off your phone then hold volume down then hold power mode. Here is where you type in your command prompts like; fastboot oem lock
fastboot flash recovery recovery.img
fastboot flash systemdata systemdata.img etc.

Thank you very much for taking the time to explain that to me. I feel much more confident in performing a root now. I will wait for the new OTA update first and see what changes. I only want a stock rooted ROM with a custom kernel with voodoo and battery life improvements, so it is time to do some more homework and see what kernels are floating around.

Do y'all think this will still work even after the update next week? Or should I root now and wait for somebody to post a rooted deodexed version of the update?

yes this will indeed still work the bootloader is unlocked.. this will forever work

Used this as soon as I got my nexus, was unlocked, and rooted with cwm in five minutes. Good work.

So, theres an update coming for the nexus s 4g next week. Will it work on a rooted phone? if not, is there an easy way to unroot it with this program?

Do you guys think we would lose root by accepting the update coming next week for the nexus s 4G?

no, there is no way to get the ota you will forever be locked on this firmware. no one will ever make a zip and upload it to xda prerooted, and rom devs WILL NOT update their roms.. sorry guys your stuck here


that will be my answer to anyone asking on how to unroot so they can get the update.

thankss the nexus s 4g is my first android phone
