[HTC Vivid, Raider, Velocity] Pirateghost:
I am excited to see the enthusiasm here and the spark of new hope to this section. It is extremely good to see people trying to get their hands dirty here.

Jazzmoe, I would like to lend a hand with this and offer a few pointers.

have a read through THIS thread and make sure you are using an appropriate update-binary and properly modified updater-script based on the recovery you are using.

MY ICS_STOCK_ROOTED updater-script (feel free to use this but try to understand WHAT it is doing rather than just copy/pasta)

as you can see, it is very basic. all ui_prints have been removed from this. if you wanted to show status on screen of what step you are on in the flashing process you can modify it with ui_print like so:

ui_print("Cleaning System");
format("ext4", "EMMC", "/dev/block/mmcblk0p29", "0");
unmount("/cache");
format("ext4", "EMMC", "/dev/block/mmcblk0p35", "0");
ui_print("mounting cache");
mount("ext4", "EMMC", "/dev/block/mmcblk0p35", "/cache");
ui_print("mounting system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p29", "/system");
ui_print("mounting data");
mount("ext4", "EMMC", "/dev/block/mmcblk0p34", "/data");
ui_print("deleting dalvik-cache");
delete_recursive("/data/dalvik-cache");

your next step after verifying it flashes properly, is to decide what apks need to go, and begin decompiling certain apks for proper editing.
