just thought I'd post as a quick note;
if you wish to restore to stock from CM7 or just go back to stock with no root or FireFireFire at all, TWRP works for it. quick tutorial:
1. download amazon's stock software: http://www.amazon.com/gp/help/customer/display.html/ref=hp_navbox_kspot_fireupdate?nodeId=200790620
2. rename it to update.zip and place on root of sdcard
3. boot into TWRP and wipe cache, dalvik cache and factory reset
4. flash update.zip, however it will stop the install mid-way and say it can not find the misc volume or something, but fear not
5. boot up and you'll be restored to stock! note FireFireFire and TWRP will have to be re-installed as well as re-root
I had issues at first boot like WiFi not working, but a factory reset changed that. now I'm gonna reinstall FFF and TWRP for some kernel action
