So I was trying to root my evo so I could try the fresh rom (please note that this was my first ever root attempt and my phone had the OTA update). I followed the instructions from this guide: Latest OTA rooted! - Page 2 - Android Central Forums This is where my problem is: 11. Once back at the Home screen type: Code: adb shell cat /sdcard/flash_image > /data/flash_image chmod 755 /data/flash_image /data/flash_image recovery /sdcard/recovery.img reboot recovery When I enter the "cat /sdcard/flash_image > /data/flash_image" code I get: "cannot create /data/flash_image: permission denied" I'm very worried I really screwed something up. Can anybody please offer up some advice for a newbie? *edit: after some googling I found other people typed "su" prior to typing in the "cat /sdcard/flash_image > /data/flash_image" command. That didn't work for me. I received "su: permission denied" after entering su. Would going back and starting this tutorial all over cause serious damage? I'm wondering if maybe I messed up earlier.
