this zip contains it (thanks to graffixnyc !)
basically, you'll need to extract the recovery.img and flash it via fastboot from your computer. That should enable OTA updates.
EDIT: this is the exact process that i went through to install the rom and enable OTA updates in one go:
(OPTIONAL): replaced twrp with
cwm touch for m7gsm to ensure the rom flashed fine.
1: booted into custom recovery and wiped data to a clean slate and flashed this rom.
2. powered off phone.
3. rebooted into fastboot mode.
4. flashed the recovery.img found in the firmware zip i posted originally using fastboot.
5. rebooted normally.
6. set up the phone as normal
now i'm waiting for android l to drop to gpe... whenever it comes out.
:fingers-crossed:
