imageIf you’ve been watching the WP7 updates you are probably well aware that Chris Walsh took an MS tool designed to fix a bug in Samsung phones and was able to push NoDo onto any Windows Phone regardless of carrier. Microsoft warned that there could be consequences to this and Chris pulled the tool after about 25,000 people downloaded it. Well Chris has just provided some detail about it:

tl;dr: Do not use my tool to update your phone.

On Monday, I released a homebrew utility that attempted to install unreleased updates to Windows Phone devices. The tool successfully passed my own tests involving multiple update scenarios.

I was later informed by Microsoft that there were several problems with my tool and the manner in which it changes phones.

Despite the fact that all outward signs indicate the phone has been updated to build 7390, Microsoft tells me otherwise. Part of the problem, the company says, is that I incorrectly used an undocumented API to deliver updates.

Most problematic, Microsoft tells me that updating in this manner will place devices in a "non-serviceable state". In its blog post describing the situation, Microsoft instead says devices updated in this manner "may" no longer receive updates

Because the tool is, in Microsoft”s words, "breaking phones", I have taken it offline at their request.

While the number of users impacted by this utility is small, I would at least like to communicate that I”m sorry if this tool causes any issues down the road. In a follow-up post, I’ll detail what your next steps should be as official support isn’t an option at this time.

What does this all mean? Well not much actually. There’ still noting from Microsoft actually confirming that this ‘does’ break phones. Of course, it would be imprudent with what we know to use the tool now but I’m not prepared to run around and panic if you used his tool. Let’s recall that when the original Chevron tool was released Microsoft stated “Attempting to unlock a device could void the warranty, disable phone functionality, interrupt access to Windows Phone 7 services or render the phone permanently unusable.”

Obviously we all take risks when we modify our phones outside of the packages that are intended for it but if I were betting on this, I’d guess that the tool works fine, phones will update as expected and Microsoft is just trying to not be embarrassed that NoDo works fine on AT&T phones even though we’re still not getting an official push.

And Chris is still a legend for what he’ pulled off…

  1. For those of you unfamiliar with this cryptic employment of quotation marks, this man is basically saying, “These guys are breaking my balls to take something both helpful and by no factual accounts harmful from you and they’re completely full of shit but whatever. Also, I intend to continue to, in stark contrast to these schmucks whose name are on the damn things, provide you with timely — and existent — support for your phone.”

  2. Can Microsoft seriously screw this up any worse? They keep issuing statements when they should be acting.

  3. Note that Microsoft could have either collaborated with this guy to get it right (were it ever even wrong) or better yet do it themselves as they’d lit out to do but they instead come out of left field with these FUD emails and blog posts.

    Could be this involves AT&T’s odd inclinations and not bad API selection.

  4. I upgraded my phone on Monday with this utility to 7390.0 and 2 days later, I received the same update via Zune. I ran it again via the ‘official way’, and got no issues during this process whatsoever. So, I wouldn’t worry about not getting future upgrades, because I did get it, albeit it being the same version.

  5. @Vince: What device are you using? After NoDo there are some specific updates coming to phones based on branding to fix things when they used their own bluetooth stacks for example… Either way it’s good news
    @Doug Simmons: my gut is 100% is AT&T right now because every other carrier (internationally) has released the update

  6. Why don’t you go to a WM7 developer website and just install a new ROM that has been tested by many users that offer feedback on how the software works in the real world.

    Oh, I’m sorry. YOU CAN’T DO THAT!

    Tell my why I should buy a WM7 phone if I have the knowledge of tweaking my own phone.

  7. Has anyone got any new app updates from there marketplace after you used the chevron update to?
