This procedure does not trigger the Flash Counter, no ! yellow triangle at boot!!!
This method will flash a custom recovery image and then you can flash the superuser.zip file or custom rom to root your phone.
This will root 2.3.5 or 2.3.6.
This requires knowledge with the use of ODIN (Read a guide).
BE CAREFUL because this can harm your phone and I AM NOT RESPONSIBLE IF IT DOES!!!!
DO NOT HAVE "RE-PARTITION" CHECKED IN ODIN!!!!
First Things you need to have:
*You Need ODIN 1.8++(CLICK ME)
*The USB Drivers for Our Skyrocket
*Clockworkmod Recovery which you are going to flash via ODIN(THIS FILE DOES NOT ROOT YOUR PHONE!)
recovery.tar MD5 Checksum 9ffa2458019af7974ef4820d0cf5992c
*SDCARD installed for CWM Recovery
*Install the drivers and make sure the Phone is recognized by your PC.
*Place the "superuser.zip" on your EXTERNAL SD card.
Or place a custom rom on your EXTERNAL SD card.
If you want STOCK rooted then use the superuser.zip, if your going to put a custom rom on anyway then you can use that rom.
***If you have never rooted or installed a custom rom before, I suggest using the superuser.zip method.***
NOW LETS INSTALL CWM RECOVERY........
*Take the battery out and place it back
*Hold both Vol up + Vol down, and plug in the USB cable.
*SGH-I727R (Rogers) users hold Vol down and plug in the USB cable.
*Press Vol up to continue to Download Mode.
*Make sure Odin recognizes your phone as in this picture.
*On ODIN, Select the PDA button and browse to the SkyrocketCWMrecovery.tar that you downloaded earlier
*Make sure the Re-Partition box is NOT checked*
*Select Start and Odin will do its thing.
*It should flash the Recovery file and reboot the phone.
NOW LETS MAKE A BACKUP AND GET ROOTED!!!
*Unplug USB, Take the battery out, place it back, and boot into CWM recovery with the button combo below
*Hold Both Vol up + Vol down and Hit power.
*Once in CWM Recovery, navigate the menu by using the volume buttons and select with the power button.
*Select "backup and restore" and then select "backup".
Now CWM Recovery is backing up your current stock rom, it will take a few minutes, be patient.
*After back-up and while still in CWM recovery...
*Select "Install zip from sdcard", choose the superuser.zip, select "YES" and let it install, you may need to flash it about three times if you get errors. Even with the error, sometimes it still works.
(follow the custom rom developers instructions for install of that custom rom!!!!).
*Reboot your phone and check for the superuser app in your app drawer.
*Now you are rooted with CWM Recovery installed!
