[Moto Z3 Play Guides, News, & Discussion] Moto X Pure XT1575:
Official Flash Commands Script

Hi Guys, Thanks for asking for help, since the 1929-4 models along with others from the Z3, each of them have a SLOT A/B that can have images flashed, in Recovery of TWRP, if you select REBOOT, you will notice your normal options at the top and the extra SLOT Options on the bottom. What you can do is select either one and apply the flash commands listed below. The Flash Commands A and B of the text file writes and sends the firmware images to those slots, you had it correct, its the SLOT Letter (A/B) that has to be applied at the end of the first character. That will get you up and running. Hopefully this helps. Let me know if you need additional information.

Have you tried just flashing "fastboot flash boot_a boot.img" or "fastboot flash boot_b boot.img" Don't forget to read your service files, they detail out that you must select which slot to flash your images to.
