This guide is to help you flash custom rom, like CM 13, in unlocked MM6.0.
The gist of this thread is to pack signature files into TWRP and boot.img so that we can boot from custom roms.

1.Add signature to TWRP
a. Download your favorite twrp. The latest official twrp is doable.
b.Download and unzip the attached file: recovery_z00a.sig
c.Copy the above 2 files in the same directory.
d.Activate cmd window in your pc (window button + R, type cmd, Enter)
e.Add signature to TWRP in cmd window: (Suppose you put all files in c:\)

Code:

---

cd c:\
copy /b <twrp.img> + recovery_z00a.sig recovery_mod.img

---

Now you will see a new file, recovery_mod.img created.

2.Add signature to boot.img
a. Unzip and extract boot.img from custom rom.
b. Download and unzip the attached file: boot_z00a.sig
c.Copy the above 2 files in the same directory.
d.Activate cmd window in your pc (window button + R, type cmd, Enter)
e.Add signature to boot.img in cmd window: (Suppose you put all files in c:\)

Code:

---

cd c:\
copy /b boot.img + boot_z00a.sig boot_mod.img

---

Now you will see a new file, boot_mod.img created.

3.Unlock MM6.0.
Refer to this thread. This is a 2 click unlock procedure. The device should be unlocked before we can flash twrp and custom rom.
4. After the device is unlocked, in bootloader, flash TWRP recovery now:

Code:

---

fastboot flash recovery recovery_mod.img

---

5. Boot from TWRP
6. Flash custom rom from TWRP
7. After done flashing custom rom in TWRP, flash boot_mod.img from TWRP.
Or, from bootloader:

Code:

---

fastboot flash boot boot_mod.img

---

8.Reboot system.
