ZTE ZMax OTA Update Files for B14/B15 (TWRP Friendly)

I've never been able to find these files, but for some reason you're on stock but have TWRP installed as a recovery, then you can easily upgrade stock to B14 or B15 without having to go through the over the air updates, since these are modified to remove checks and to flash completely in TWRP.

So if you need to go back to stock B13, here's your easy upgrades. :)

Edit: For each of these updates, you will lose root. For safety I would reboot to let the upgrades go, reboot to TWRP, and reflash your choice of SU.

You are braver than I sir. I wouldn't ever flash those, but if you say it works

I modified and tested myself to see if I needed to move to B15 to get calls working on Nougat from the B13 firmware. It didn't, but I figured someone else may benefit from the work.

Hey, I'm still on B14 (Z981V1.0.0B14), what does the B15 update consist of? Android Nougat or bug fixes? Sorry, I'm kind of a noob.
 
These are just the OTA bugfixes for the ZTE Zmax. Lineage OS (and others based on Nougat) are being worked on in other threads in the forum. I just put these here in case someone wants to go back to stock and not have to deal with OTA updates if they want to keep their custom recovery (TWRP, etc).
