1)you will need to remove whatever PH98IMG is lingering on your sd card. this is one thing i hate about the roms auto-placing a PH98IMG on the sd card,then booting you to bootloader to flash it.
after installing a rom that does this:
YOU WILL NEED TO CONNECT TO YOUR PC,OR USE A FILE MANAGER,AND DELETE PH98IMG FROM YOUR SD CARD. easiest way is to put the sd card into a card reader,or even another cell phone that you can plug into your PC.
2)you will need to relock to run the RUUs. if you want to run the leak RUU to get the new firmware,it may save you some fustration to run the one for 2.01.605.11 first,if you are not on stock softwware.
on the other hand,if you are wantin to restore a backup before flashing,for whatever reason,all you need to do is this:
-place your recovery image into your folder containing adb and fastboot
-boot to hboot(after removing PH98IMG)
-select fastboot with power button
-enter this command to launch recovery:
fastboot boot recoveryname.img
that will boot your recovery into phone memory from fastboot,letting you restore a backup without haveing to flash a kernel seperately.
