(hboot 1.40 one is broken, won't unzip, 1.58 one works fine)

relock your phone.(you need driver in window. I just use linux as everything works out of box)

adb reboot bootloader
fastboot oem lock
adb reboot bootloader (shows relocked)
put your PG86IMG.zip at the root of your sd card. Let it update.
adb reboot bootloader
fastboot flash unlocktoken Unlock_code.bin

stock kernel needs hboot 1.58, custom ones need hboot <= 1.4.

flash custom roms
flash hboot first, using PG86IMG.zip with hboot only in it.
reboot to recovery, flash roms.

google now launcher on kindle fire hd 7 with cm11

I installed google now launcher from play. It kept asking for newer version of google search, but my search is up to date. Googled a lot, and found a work around. Some steps may not be necessary, but they worked for me.

remove google search apk form system, uninstall google now launch, install nova, uninstall cm11 default txxxxx launcher

reboot

install google now launcher

reboot

install google search

reboot

load google now launcher, ask for newer search again. load google search. uninstall google now launcher. re-install google now launch.

Then, it works.
