I disagree from the op.
Every change to device firmware compromises the warranty, not just bootloader, read the agreements ... If you exploit a bug to have root access, you will have to fool everyone who will have contact with your phone so they don't see what you have done. Even if you try to "reverse" the root, you(or the program you use) will always leave a trace.

We should be promoting "unlock the world"
This is not to imply everything should be free, however if I own something it should be mine in every regard, that includes breaking it.

I have xt925, first thing I did was unlock boot loader. Then I updated ota to Telstra JB. OP is misleading people.

Once again.

A) The reason why the page says "no updates" is beacuse OTA updates only work when you're on stock firmware, which is unlikely when you have the bootloader unlocked. That's all.

B) There are things that such "agreement" cannot contain. Being unable to sell the phone is one of them in most countries.

To end my part in this discussion: The limitations, restrictions & disadvantages of unlocking the bootloader are much greater then any benefit or gain under the current availability of development !

I did not notice your response at first, now to the point -
Without any disrespect to the work, time & effort invested, the main point is being ignored by the developers: All comments I got on this OP didn't touched the number one reason of my suggestion to not unlock the bootloader: There in not really enough of a variety of development options today to justification the bootloader unlocked of the xt925.

Can someone elaborate on this point; I read in another thread that when you remove all rooted apps and data, clear out the files left in /system, that there is still info stored stated if the device has ever been rooted, and that this can be cleared using an app on a PC (don't remember which) however when I looked at the app it was specific to the XT926 and thus I wouldn't be able to use it.

After a thorough clean of every rooted app and everything left behind by rooted apps, is there a known way (or assumed to be working way) on XT925 to erase the record of the root.

Also, assuming I was to get my phone back to that state and remove proof of root, what specifically do I need to do in order to be careful as stated... or is epinter correct in saying that there is always a trace left behind, and if so, is this a blatant trace or something that hasn't been of much concern for Motorola in the past when servicing phones?

How would I return to a stock bootloader if I were to unlock mine and an OTA didn't work? How did you do it?

It's your decision whether to unlock the bootloader or not. I'm just saying (for other users) that many of the cons you wrote were absolutely incorrect.

I believe there is something stored in the pds partition. Or at least it is that way on Droid RAZR XT912 and you had to fix it to remove the remaining traces. Flashing FXZ is also a way how to get a clean stock firmware, but pds partition is not affected that way.

I think he meant "stock firmware" instead of "stock bootloader"

So if that were the case on this phone, I wonder if doing a dd backup of the pds partition before rooting at ICS, for restoring after downgrade, would be the way to go. Assuming it restores properly, it would be a good thing to add to the sticky thread about rooting. I did a dd of all my partitions except for /data last night, but I'm already rooted.

hmm... I'm wondering if there's something inaccessable in /system or even the sdcard since they get mounted with fuse. My only other Android phone was the Galaxy S II which was pretty straightforward and dead simple to root and unroot. I was surprised to see the fuse module being used to mount anything when I got this one.

The original topic is here: http://forum.xda-developers.com/show....php?t=1857558
I don't know if there was a proper fix developed (haven't checked) on the RAZR.
