Finally....fast camera...check....faster homescreen....check...better battery life....check.....system standby battery percentage reduced significantly...check.....new radio...check....new kernal....check....new webdock....check
How did this happen you ask? Let me show you. BUT I am going to give a HUGE warning in advance. I did this without a hitch and almost too easily.....but others are having trouble so I feel I should make it clear....FOLLOW ALL THE STEPS AS THEY ARE POSTED OR ELSE.....oh....and of course I NOR XDA OR BIONICFORUMS.NET OR DROIDFORUMS.NET ARE RESPONSIBLE FOR WHAT YOU DO TO YOUR DEVICE. Another warning....THIS MIGHT TAKE YOU OUT OF THE UPGRADE PATH...meaning you might not get the OTA should it be different than this. But....there is a work around for that should that be the case.
Did you think that was the only warning? It isn't. I am going to link to the thread and post the quote directly from P3 himself
Here is the thread
Motorola Permanent Root - xda-developers
Here is the quote
"I am posting this here in hopes that some of you heed my warning.
The permanent root method was released so that when, and its coming, when motorola pushed out an update you would maintain root through the update. I never intended for everyone to use it to update their devices to 5.5.891/892/893. Updating to those updates still bears some risk as you are officially off the update path until we find out what the next update is, and if it is not one of those listed above, you could have your phone stuck not being able to fully update.
Truthfully, I think people should have fun and that is what android is about in my eyes but just flashing newer builds to say "hey I'm now on .893" is not, in my opinion, prudent.
How the root method works:
When init runs at the start of the booting process is runs files in the init.rc, one of those files is mount_ext3.sh. When you add that code to the end of the file you have told the kernel to give the 4755 permission to su, which means you will always have root.
How to check if it works:
This part opens your phone up and is dangerous, I only use it to check to make sure my script is running correctly.
add the following line (this will perma mount system as r/w DANGEROUS) mount -o rw,remount /dev/null /system.
reboot your device.
using rootexplorer (or something similar) go to /system you should see MOUNT R/O in top right corner.
if you see that then I suggest going back to mount_ext3.sh and removing the mount command.
---------------------------
There you have it, be careful.
****Always ensure that your mount_ext3.sh is given correct permissions 4755 ****

OK...if you read that and still want to continue....keep in mind I mentioned a work around which will get covered....then here we go.
What you need:
YOU MUST BE ON .886 WITH ALL BLOAT UNFROZEN AND PRESENT....if not FXZ back then continue
Bionic Bootstrap
Root (duh)
Cheesecake app (will link to that)
Root Explorer
Patients
Got it all? Let's continue
First things first....let's ensure that we retain root through this process. Once again thank you P3 for this
Open Root Explorer
go to /system/bin
on the top right click on the Mount R/W (should change it to mount R/O)
look for mount_ext3.sh and open it in the Text editor (long press then scroll down)
scroll to the bottom of the script then click enter twice adding 2 blank lines
now type in the follow 3 entries EXACTLY like I have them below
- chmod 4755 /system/bin/su
- chmod 4755 /system/xbin/su
- chmod 4755 /system/app/Superuser.apk
then click on the Mount R/O so it changes back to Mount R/W
some are saying you need to check mount_ext3.sh execute permission after editing but I didn't do this.
Once done reboot your device. Congrats....you just obtained permanent root that SHOULD according to P3 survive any OTA.
Next let's make a backup of our current setup....just in case
Open Bionic Boostrap, select first option, wait for success, select second option...when phone boots navigate to backup and restore, backup, and make a backup of your current setup.
Next....let's set ourselves up to get the new update...what do you say?
Download and install the Cheesecake app which you can find in the first post of this thread
*Bootloader Unlock Research* Cheesecake Clarification - xda-developers
Direct link to download
http://db.tt/dDxs8cQ4
open the app and click on the first option "Click to create proper files"
wait till complete and you get indication of success
Reboot your phone
ok....so here is the tough part....Let's get the update
Open the Cheesecake app again
select second option "Click to change server"
click on "staging"
click on "master-staging1.blurdev.com
now click the third button "Check for updates"
you will be greeted with a pop up saying it requires a Motorola Service account....just click setup to bypass it
you will see several options....but only 2 are of importance to you right now...and only 1 of those will get you to where I am. The 2 of importance are.....
5.5.893
5.5.999
what's the difference?
893- is a new update that provides a new radio and kernal....as well as enhancements to memory management, the camera (big time) as well as resolves a few issues I was experiencing like 4g staying on while WiFi is on....then not connecting to 4g when disconnecting from WiFi. In addition it took my Standby battery usage from 20% to 2%....yeah....battery life seems to be endless now as well.
999- this is said to take you back to 886. Should you have issues in 893 you would open Cheesecake and take the download of the 999. Once installed you should be back on 886. This is the work around I was discussing.
Keep in mind this "work around" is purely theory as far as I know. I can't verify it as I can't see the 999 now that I am on 893.
So....you are going to select the 893 for the update. However....I just found that one 893 you don't see the 999. So can someone download the 999, select install later or something and email me the zip.
When you select the 893 you are going to.....well....sit back and watch. It is an OTA from Moto that downloads and installs just like any OTA you have ever taken.....not so tough right?
So....there you have it. Many notice a huge difference in Camera speed and quality. Also noticing definite speed increases with the navigation of the phone including the default launcher and performance of 3rd party launchers such as LPP. I haven't found an app that didn't work yet. 4g signal seems stronger than ever and much faster to connect. Haven't had to reboot yet for anything.
Some are reporting being able to FXZ back, permaroot (addressed above) and were off to the races....others claim to be stock on older OS with new Kernal and Radio...some even claim to be in the hybrid stage without root.
There are ROM's such as the new Theory ROM that already use the new Kernal and Radio so I don't believe you will be stuck as there are options out there.
Take heed to the warnings....this is not for the faint of heart.
All of those with issues that I have read so far did NOT follow all the steps as I posted them. They either did the ADB way...didn't change it back to R\O, or something else.
Here is the original XDA thread where I learned of this. It is way active and plenty of updates are coming along...
