Motochopper updated to 1.2. I added a link to the RAZR HD specific thread for motochopper so I don't have to keep updating multiple places every time I make a change. I separated things into specific directories (boot_new, boot_old, system) so that it can be updated going forward. Obviously boot_old will have to remain the same, but, if you get a new update you can try sticking the new boot.img into boot_new and see if it works (let unlocked users test it first). The system dir is used for when you need a clean start with the system partition to remove any remnants of root left over from a previous install. If you drop the system.img.ext4 file from the FXZ into the system dir, it'll flash that as part of the rooting process and should give you a fresh start. No promises that you'll be able to use this going forward but it's at least an attempt at making it a little more future proof by allowing people to swap out the boot.img file in boot_new with the latest one from whatever update is current.
For people on phones other than the XT926 and the 79 update, you can try adding the previous boot.img from whatever update worked with motochopper originally in boot_old and then the boot.img from your latest update in boot_new. Again, no guarantees it'll work, but, it's worth a shot.
