[QUOTE=dags5000;[URL="tel:1932682"]1932682[/URL]]fyi - i followed the directions exactly as well and it bricked my phone. wont boot anymore. just a warning. curious if anyone knows what i might have done wrong. After i ran the 3rd step where it "flashed" the boot or whatever it did, i tried to reboot and thats where it just failed on the boot. reflashing the system didn' fix as the kernel was hosed. did anyone else experience this and have advice on how to fix? the error i get is Invalid CG Version (CG: boot) in the AP fastboot on load[/QUOTE
That is supposed to happen. The boot error is normal. You would then boot into stock recovery and apply the 5.5.893 update which you need to have on your sdcard.
Since you tried to do some reflashing then you may have messed that up. If the update does not work then use stock recovery to wipe data and cache and then reboot back into fastboot and use Releasedroot v2.1 option 1 to get back into the os and then start over from scratch.
