Last night on the Twitter, Chris Walsh, aka one of the people who brought ChevronWP7 to the masses, was working on something "big", having Raphael Rivera testing something related to those new tools release by Microsoft. Those tools were meant to fix two rare but possible update errors people may be experiencing with the NoDo updater.
Turns out, when modified, those tools were able to force pre-NoDo and NoDo updates to any phone, any carrier with any language. Indeed. There's no sideloading here, no modifying of registries, etc. Just a multi-step process that will bring you the update to your phone right now.
Basically they’ve created a managed wrapper over the whole update process for us, rather nice of them.
So I flashed my HTC Mozart back to RTM (7004) via a ROM update HTC ship and whipped up a little application to flash pre-NoDo (7008), NoDo (7355), NoDo update 1 (7389) & NoDo update 2 (7390) all in a single process. No I don’t care which carrier you are on, which phone you have, it’ll just update your phone accordingly.
We really have to commend Microsoft here for being able to split up the OS updates into differential packs, which saves users downloading 200+ MB updates, unlike the IFruit updates.
All you need to do is run the ChevronWP7.Updater.exe console app and follow the prompts.
