Install MobilOdin from the Playstore. Use it to flash CWM when you need to, such as flashing ROMs and mods. Download a custom recovery CWM kernel (.tar file) and keep in a folder on your sd card on your device. You also need to download a copy of your stock kernel (.zip file) and place it in a folder on your sd card. Open MobilOdin, scroll down to "open file", select the folder containing your recovery kernel then the kernel file itself. After selection scroll to and select "flash firmware". You may want to use the EL26 CWM or the EL29 direct boot recoveries. If you use the EL26, press and hold the volume up and power button together while the device is displaying the "SGII" screen after flashing CWM. This will get you to recovery. The EL29 will get you directly to recovery. I have had good results using either one, however, use the recommended recovery for whatever you are flashing. Assuming that you are on a stock TW ROM (FK23 for example), upon completing your flashing from recovery you will need to flash your stock kernel (the zip file you placed on your sd card prior to this proccess). You will do this from recovery. Scroll to "install from sd card" (internal or external) and select the folder then stock kernel. Reboot device. Device will re-boot back into recovery without the stock kernel upon your attempt to re-boot. I have also been using Agat's new FL16 repack custom recovery the last few days. I flashed the new GA10 ROM leak and a tweak package with absolutley no issues encountered. All the above mentioned files can be found on Rwilco12's repository website.
