Root Official 2.3 Rom?

Just found this HTC Desire Android 2.3 Upgrade on the developer site. Is this a Rom similar to other Roms that can be flashed from recovery, or is it just for developers?

HTC - Developer Center

Just curious. Not a developer of any kind; and I'm betting it won't address the memory issue either (no A2SD etc) so won't be trying it.
 
It's an RUU. Not flashed like a custom rom - plug phone in, and run the .exe and it flashes the phone. HTC advise it's for devs, but it looks like lots of non-devs have run it.
 
OK, thanks for that. Not going to bother TBH as I don't want to lose support for A2SD. Pretty sure it will form the basis of some roms in the near future. Maybe even clear up a few bugs.
 
I certainly wouldn't flash it, since it will unroot the phone and (try to) install a new hboot (version 1.02), and I'm not sure whether the current rooting tools can handle that. You could well be stuck with a bare-bones Gingerbread+Sense 1.0 ROM with fewer features than the ones you've been able to install from XDA for the last few months.

I say "try to" above because if you are S-Off and using one of the new alpharev hboots that should survive the RUU, leaving you still S-Off and hence free to flash a custom recovery and then install a rooted ROM again if you want. But my curiosity doesn't extend as far as testing this myself ;)
 
I've given it a go. Was a bit dubious due to fact you can't root at the mo or revert via an older RUU but I have drifted back to Sense in the last two weeks and had a moment of weakness! Works great to be honest and it'll probably be rooted in the future.
 
OK, that's good news :)

I'm sure it will be rooted in the future - hboot 1.06 has fallen, as has the Desire S and even the Sensation, so it's only a matter of time.
 
Revolutionary (alpharev/unrevoked beta) would also be worth a spin.

But again, I'm going to wait for someone else to try this :)
 
A few thoughts on this RUU. I have not installed this and dont aim to. But I can see that the build no for this RUU is 3.14.405.1. The 405 is the wwe series. But this is supposed to be RUU for all regions. When the androidinfo.txt file is checked against the 2.29.405.5 file then you can see that a lot of magic is there:-

So you can see that though it is 405 series it is allowed on most region devices since a large no of cidnum with wildcard * placeholders have been included in the RUU. This would indicate that it is not the series no like "405" that is important for deciding whether to allow an RUU. It is the cidnum actually which you can read with fastboot getvar all.

HTC quote "Please note that the following regional variants are not compatible with this upgrade: Germany (Telekom Deutschland), North America, South Korea and Japan.". I am guessing their cids are not in this list.

The hboot with the RUU is 1.02.0001. I wonder if HTC has given a unlocked bootloader as they have been promising.

Dont know what radio they have included though. I guess you will come to know only if you install.
