Seems to be a lot of problems with this so here we go again..
1.Make sure you have the Samsung Drivers installed on your pc
2.Down load the tar file from CWM and place in a folder on your desk top named Centura.
3.Download all the files for root from kingmt01 post, place those in the centura folder
4.Download odin. place that in the centura folder. Now we have every thing we need.
5.Make sure you have a sd card in your phone.
6.To get into download,hold vol down and power till your phone vib's then let go of power,you will have a warning press vol up to get in to download mode.
7.Open odin plug your phone in,if you done every thing right so far you will see a yellow box in odin with a com # in it.
8.Click on the PDA button find your centura folder and click on the tar file.
9.Uncheck the reboot box,hit the start button,let it do its thing,it will have a green box that says pass.do not turn off your phone.
10.Now unplug your phone and hold vol up and power till it vibs let go of power only,you should now be in CWM.
11.Now scroll to backup and restore and make a backup.Let it do its thing,when done reboot.
12.Now plug your phone back in,let your pc find it,when it does it will have a sdcard and usb storage click on sdcard,you will see a folder that says clockworkmode,open that up and you will see a folder that says backup,open that up and make a new folder in there and rename it root.
13.Copy and paste all the files from kingmt01 post in the folder you just made called root.
14.Now close all the folders,and reboot into recovery,hold vol up and power till it vibs then let go of power,you should now be in CWM.
15.Scroll to backup and restore, restore,clockworkmode,backup,root,hit thge power button to install,if you done every thing up to this point right you will see it backing up.when it says restore completed you can now reboot your phone.
16.Pat your self on the back you have just rooted the Centura....this may be long but it will work....read read read then do...if you mess it up its no ones fault but your own
After you boot back up you will get a popup wanting you do update,click install and it will reboot your phone into clockworkmode will give you a warning its not signed, make sure no is highlighted and hit the power button,your phone will reboot and no more pesky popup. you will still get a yellow ! you can either get a jig for it or wait till the rom is released.
