Because of the Locked Bootloader, the Stock Recovery cannot be replaced.
Safestrap Hijacks the boot process allowing for a custom recovery (TWRP)
In this custom recovery, Custom Roms can be installed, along with other functions that a custom recovery allows.

17 Aug 2015: Currently the newest version is Safestrap 3.75
Cm12 requires safestrap v3.75 (or newer)
3.75 is compatible with older roms.

Creating a Rom Slot
Rom Slots are created in Internal Storage/Internal SD Card
In Twrp
Select Boot Options
Select a Rom Slot (1-4)
Select Partition Sizes
Sizes depend on Rom, Gapps, other Apps...
Partition Sizes cannot be changed again without deleting Rom slot.
Start with System: 700MB Data: 2000MB Cache: 10MB (For Lolipop)
Selected Space cannot be larger than Free Space
Select Create Rom Slot
This will take Several minutes
screen will likely go black
Don't worry screen time just timed out, tap touch screen to wake.
After rom slot is created, it should be automatically selected.

If you are Installing on Stock Slot, Backup Stock Rom first

Download Rom/Gapps
Verify Roms MD5 with a Checksum Utility

Installing a Rom
Make sure the Rom Slot you want is selected (see 2nd line from top of Twrp Screen)
Select Wipe>Advanced Wipe>Check Dalvik Cache, Android Secure, Data, Cache, System
Swipe to Wipe
Home screen
Select Install
Select Storage option Internal or External SD card that rom zip is on.
Check Storage Option (Internal storage or External SD Card)
Ok
Browse to file and select
Swipe to Confirm Flash
Should take a min or 2 to install, watch for errors
if you see any errors, rom may not boot correct
it may not say successful or complete
when you see Wipe Cache/Dalvik and Reboot options it's done.
Select Wipe Cache
Swipe to wipe
Select Back
Select Reboot
Rom should should boot within 10 mins, if it doesn't something's wrong.

Many Custom roms don't include Google Apps/GApps (playstore...)
Sometimes Dev posts a link to preferred GApps version.
For the XT910/XT912 I suggest installing a Minimal Gapps because of the smaller System size and lower memory compared to newer devices, like pa_gapps-modular-nano...

Be sure to install a GApps Version that matched Android version of Custom Rom.
See sd_shadow's Collection of GApps Links

Install Gapps zip after installing rom
using same steps (do not wipe data)

if you have a XT912 or XT894, There is a Modified Safestrap 3.75 for unused partitions (/preinstall & /webtop) by Mentor.37
Safe Slot uses
/preinstall (~ 600mb) for /system
/webtop (~ 1,4gb) for /data
/cache is shared with the Stock Rom slot

Using Safe Slot
Same as other slots but must also install flashable ramdisk for not stock based roms cm11, cm12...
Ram Disk for XT912/XT894
CM 12.1: ramdisk-update.zip
CM 11: cm11's_ramdisk_for_safestrap_for_unused_partitions ..zip


Fixing Safe Slot
try
Wipe>advanced>check system>tap Repair or Change File System (@ top of screen)
Tap change file system>Tap FAT>swipe to change
wipe>advanced>check system>swipe to wipe
Wipe>advanced>check system>tap Repair or Change File System
Tap change file system>Tap EXT3>swipe to change
wipe>advanced>check system>swipe to wipe

XT894: http://forum.xda-developers.com/droi...tions-t3023932
XT912: http://forum.xda-developers.com/droi...nused-t3032675
Note: Mentor.37 has removed the Safestrap splash screen, so you must select reboot to recovery from rom or Boot to safestrap from Stock Boot Mode Selection Menu
