I followed 8, and flashed the latest CWM via Odin, then rebooted into Recovery and applied the Charge-FP1-DeoDebloatedRooted.zip update, then shut down and connected back up to Odin and installed the FP1 Stock Kernel.
Then I rebooted into Recovery again and tried to apply teh FP1 modem, but got an error. So I Odined the EP4D modem, then reboooted back into CW and applied the EP4D to EP1 modem patch and it was successful this time.
But when I rebooted the phone, it goes to the "Samsung" screen and never gets past that. Any idea what happened and how I can fix this?
