Motorola Droid Turbo :: Stuck Trying To Clear Cache Partition

I have a Moto Maxx XT1225 but I believe clearing the cache partition is the same as the DROID Turbo (it's immediately below my question).

I always get hung up after step 5 (below) - i.e., when I press the up volume 10-15 seconds and then tap the power button, NOTHING happens...no additional menu options appear as listed below for step 6.

FYI, here's steps 1-6 as mentioned above:

1. With the phone powered off,*press*the*VOL*DOWN KEY*for 2-3 seconds then*POWER*key then release;

2. The device will display*different BOOT*OPTIONS;

3. Use the*VOL DOWN*Key to SCROLL to Recovery*and*POWER*Key to select;

Tip: If the device reboots, you may have*waited to long to make a selection, you*will need to begin the process again.*

4. The device will display*the*Motorola logo and then*the*Android in distress*(logo with Exclamation mark);

5. Press and hold the*VOL UP*key for*10-15 seconds.*While still holding*the*VOL UP*key*tap and release the*POWER*key;

Tip: You can*try this step, holding the phone in landscape. If you are*stuck on step 6, try a*force reboot by pressing the Power key and Vol Down key, and start the process again.

6. The device will display additional menu options (Text will appear in*BLUE);
