Ok since there seem to be problems with getting the ext4 to stick I odined back to stock EE4 to figure out what the problem was and maybe to try and come up with a foolproof way to do this... I came up with this simply as an alternative or to give more details for those who need help, not to detract from the original instructions. It has more steps so may take longer but I did it 3 times in a row starting from stock and had no issues whatsoever getting to GummyCharged GBE 1.9RC2 with ext4:

*THERE IS CURRENTLY A BUG WHICH WILL MAKE CWM WIPE YOUR PHONE AND REVERT YOU BACK TO RFS IF YOU BOOT INTO IT AFTER FLASHING THIS ROM AND ACTIVATING LAGFIX/EXT4, SO BE WARNED THAT BACKUPS/RESTORES DO NOT WORK... ONCE YOU'RE UP AND RUNNING DO NOT USE CWM*

*Make any necessary backups before as these will completely wipe your phone*

You will need Odin, the stock EE4 odin file and PIT (if you need to odin to stock), the Odin version of CWM, one of Imnuts' voodoo kernel .zips on your sd card, Kejars' GummyCharged FE 1.9 or 1.9.1 .zip file on your sd card, and Kejars' GummyCharged GBE 1.9RC2 .zip file on your sd card, and the EP1Q modems

It's long but here goes:

1) make sure you're on absolute stock unrooted EE4, odin back to it with the PIT file if needed

2) odin CWM, boot into it and flash a voodoo kernel (I used Imnuts' 7/31 kernel as that was what I had on my sd card and was too lazy to update it)

3) boot up and let it convert your partitions, then let the phone start and shut it off

4) boot into CWM and wipe DATA ONLY then flash Kejars' GummyCharged FE 1.9.1 and let it boot up

5) there now you're on GC FE 1.9.1 with voodoo/lagfix enabled, go into terminal emulator and type 'su' and enter, then 'mount' and enter

6) in the lines of info you need to look for /system, /data, /dbdata, and /cache and right after all four should say 'ext4'

7) now power phone off and odin the EP1Q modems

8) you should now have a phone with GC FE 1.9.1 voodoo/lagfix and EP1Q modems, you can boot to check if you want but its not necessary

9) boot into CWM and again wipe ONLY DATA and flash Kejars' GummyCharged GBE 1.9RC2 and boot up your phone

10) congrats you should be rooted, have the EP1Q modems, partitions ext4'd and running GBE 1.9RC2... check the about phone section in settings and make sure firmware is 2.3.4, baseband says 'i510.06 V.EP1' and 'SCH-I510.EP1' underneath it, kernel is '2.6.35.7-EP1Q-CL397514' and baseband is 'SCH-I510.EP1Q'

11) now repeat steps 5 and 6 and the four main partitions should still say 'ext4', if you want to run quadrant a few times you should top out somewhere in the 1600's or 1700's and this will also let you know it worked

12) you now need to odin Imnuts' new CWM again if you want to make backups/restores as Kejars' zip does not include this updated one, though I think restoring a previous rfs rom will convert you back to rfs so be careful... you can always find Nitroglycerines' Ext4/Nameless kernel thread and use those instructions with the provided ext4 formatter and that can reconvert you

This along with Kejars' OP will 100% get you there, I have tried both ways numerous times myself to try and duplicate the problems people are having and it works every time... However I only recommend these steps as a last resort as they're time consuming and specific, I know Kejar/Team Gummys goal was to make a rom you could get to from anywhere else. Enjoy :) and as always a HUGE thanks to Team Gummy, Imnuts, and the rest of the devs for putting all of this together for us :D
