Haven't seen anyone post an update.zip for this yet, but this is the radio img that comes with DMD64. I've used it on both 32B and G1 running latest Cyanogen.
This has been pulled from the official update DMD64 from Lucid REMs site. All I have done is pull the radio image from that.
Hope this helps.
This has been shown to work on several different versions of Dream/Magic 32B. However, please make sure you have an upgradeable radio version. ie. 184.108.40.206I
There have also been instances where the Market App will not connect data-wise. brentlacydotcom found the solution (completely I hope). Those with WebGuard might have to have it removed because it does not play nicely with the new radio. Go here for info about Webguard.
Okay - Updated to have two different files
This one is for G1 users:
MD5 Sum: faf0db41d28daf1cefefc7be0fceb55c
And this one should work for myTouch 1.0 users:
MD5 Sum: 9c022efeef83df4c6b5c03a7c5812d03
1. Put either file onto the root directory of your sdcard. [/sdcard]
2. Boot your phone into recovery mode. [Either Cyanogen or Ra's recovery works]
3. Apply "any .zip" update and point it to the file.
4. When prompted, reboot your phone.
5. Patiently wait (the flea circus will do their job within your phone)
6. It should put you back into recovery, from there, reboot and you should be good.
Christopher Chavez over at Android and Me posted a great YouTube instructional video for all. Check it out here.
Just to clear things up. I don't advertise that this radio update will change your life, get you laid, or help you win the lottery. I have only posted this update because it is a new version of the radio. That's it. It came from a need (my wife was complaining of call quality issues) and I wanted to share it with the community. I would love to say this radio update will change your life...really I do. But to be honest, it is just a step up from the 26I firmware. I'm not even advertising that it's an improvement. I have seen results on mine and my wife's phones but that's it. Your experience can and will be different than mine. That is just the way hardware works. At the end of it all, if you are getting positive results from the update - awesome. If not - well, my apologies and hopefully when T-mo rolls out the actual official update, it might come with something different.
For those of you that want to go back, here is the direct link to the 26I version.
