Root Way to revert your phone back to full stock to accept any update

[johnlgalt]

Thanks to P3Droid and this post How to get your phone back on the upgrade path... you can now revert back to pure stock including Webtop files so that you can take on any update. So, now you can go ahead and flash the 5.7.893 update and not be fearful about never being able to update again.

I'm taking this directly from that thread, all credit goes to P3Droid for the procedure.

This has only been tested on Windows 7 (32/64)

Spoiler

1. Download this fastboot file http://www.mediafire.com/file/4usz2227c427p6d/moto-fastboot-win32.zip
2. Download this Zip (Contains both System and webtop images) http://www.mediafire.com/file/c545ow7tnetawe5/Get-to-stock.zip
3. Create a folder on Desktop named {anything you want} (I recommend you keep it simple)
4. Place the contents of both zip files in the folder you just created
5. Put phone in Fastboot mode, connect to computer (click show to see how)
   
   Spoiler

   • Power off phone
   • Press and Hold BOTH Vol Up and Vol Down
   • Press the Power button until the main menu appears
   • Use Vol Down to move selection until you are on Fastboot
   • Use Vol Up to select
   • At next menu, connect data cable
6. Open a command terminal (run cmd.exe) and go to the folder you created (cd Desktop/{name of folder})
7. Type in the following commands, one at a time, and wait for them to finish executing before typing the next command:

   • moto-fastboot.exe flash webtop grfs.img

     (This file will be flashed in 4 parts)

   • moto-fastboot.exe flash system system.img

     (This file will be flashed in 2 parts)

   • moto-fastboot.exe reboot

Your boot image (kernel) and radio files will never go back to stock !!!

Your phone is now back on stock (well the parts that matter anyways) Congratulations.

Wish I had seen this post a few hours ago.
Might have saved me some time and avoided a few "Oh Sh**" moments.

Thanks johnlgalt

Sooo... *scratching head* ... if I rooted using Pete's and the unrooted with Pete's (which I assume worked, btw, it didn't exactly give me a fanfare screen saying I was unrooted) I should be good without doing this procedure, right?

 

[johnlgalt]

Easiest way is to open a terminal and try to run the

su

command and see what happens - if it is still rooted, the prompt changes from

$

to

#

. If not, it should give you an error message, but here is where it gets tricky.

If the message is something like

Unable to find su

or

No such file exists

then you're good.

If it says, instead,

Error, unable to [B]run [/B]su

then it's still there, even though you no longer have root privileges.

BTW, this procedure is an alternate method of restoring back including the Stock Webtop files so that you can apply the 5.7.893 update onto your phone. It's aimed primarily at people who applied some sort of Webtop hack and / or fiddled around in the Webtop partition for whatever reason.
