I just want to let everyone know that it is possible to go back to ICS after updating to 4.1.2(9.16.6) I was rooted on 4.1.1 today, used ota root keeper to temp unroot and update to 4.1.2 and restore root. I just used Matts RazrHD utility 1.10 and went back to ICS 4.0.4 with no problems what so ever...
Im not sure why its stated that once you update to the newest release that you cannot go back, but its possible. So for everyone that wants to try out 4.1.2 and didnt want to be stuck, you can downgrade.
Hope this helps.

This was done on my phone:
Device: XT926 US Verizon non dev ed.
Original firmware 4.0.4(0.6.25)


Update: 3/21 I attempted to downgrade again today with no success! It now gives me errors. I tried everything I could think of, but it will not work. I cant see what could have changed within one day, but something did. Maybe its something that was sync'd with my phone from moto. that didnt sync before last first time I upgraded or an app I really don't know. My phone still works and is still rooted, but until there is a safe way to downgrade do not try... This is the weirdest thing I have seen. And to let everyone know, there is no reason I would have lied about downgrading the first time. I would not of posted this in the first place.

That is good news... Did you take the update via OTA or through the DroidLife article/post or some other notable source?

Dru can you go back on JB 4.1.2 and try to fastboot again to see if you get the same results. No one wants to try

I am starting to call BS on this one.....please prove me wrong.....

No it wasnt bs, I downgraded successfully yesterday.


I had some problems with my comp. and the usb/moto drivers on win7 today so I was trying to fix that before I could try again. I attempted to downgrade/restore to ICS again and this time it did not work! I cant see how it worked for me yesterday and today it wont? I was so happy when it worked, but something must have changed within the last day which is odd. I always upgrade and root the same way, and I have tried everything today to get it to downgrade with no luck. My phone still works so it is not bricked, and I apologize to everyone, like I said it did downgrade yesterday with the RazrHD utility 1.10 and there were no errors what so ever. Now after it asks you to hit any key once the phone comes back on in FB errors come right up. Some things seem to flash though, which is strange and basically it does a factory reset on the 4.1.2 . SS is still installed, its still rooted, and works fine. I can even restore back up of 4.1.1 stock jb(which I made last night after I downgraded to ICS and was upgrading again) on stock slot after wiping data/cache/dalvic and system and boot up to show 4.1.1 and then either try to downgrade, which fails, or take the ota and/or flash 4.1.2 manually but it fails also. Then I just reflash a back up of 4.1.2 and its fine IDK... I also flashed Vit 1.9.3 on stock slot fine, boots etc. but still wont let me downgrade. Then I tried uninstalling all updated apps on 4.1.2 and clearing data on all apps, still nothing.

So for some reason it let me successfully downgrade yesterday, but not anymore. So like many people have said do not try until there's a safe way, unless you are willing to risk bricking.

Ok, This is an odd situation, I want all to know that this has not been possible so far, and is being tested/confirmed..

so others do not Brick while he is testing things I am locking this until either a PM is sent or he posts his findings and I can merge them into this one..

Please no offense to the OP, but as of now 3-21-2013 there is no going back to ICS once this update is done,

Until then Please see
