from what I remember when I was looking into this a couple months ago, deleting the tree.xml didn't do anything if you were actually missing your certs.
(I thought I had this issue before but it was an odd combination of radio versions and rom versions. Newest radio (at the time) refused to connect or even attempt to connect to WiMax but flashing it down a few versions previous suddenly it was like nothing had ever happened.)
The 'start over' method doesn't fix anything if the certs are actually gone either.
Sharing keys was reported to work but only one can authenticate at a time.
iirc they were using ridiculous levels of encryption on the key (128 or 256? i don't remember, but it was excessive for what it is) so regenerating the keys on your own is going to be a lot of fun until some tenacious (and bored) crypto gets a whole bunch of other peoples' certs to reverse engineer the thing.
I hate to be the bearer of bad news but there's a very good chance that your recovery didn't bother backing up that particular partition; some didn't back then.
I haven't looked into this since about September, so maybe a lot has changed, but at that time if your keys were actually lost you were actually not going to get them back without direct help from Sprint/HTC. The keys are generated by HTC at time of manufacture/assembly and I haven't heard of any way to get them back. There was talk of hope since there was a utility from Sprint that allowed people to get their certs flashed back into their "4G" aircards, but I have not heard of any such utility for the phones yet.
Let's hope I'm completely wrong and something drastic has changed.

awesome! im over it. im back to my snappy cm6.1.2 with savage sbc kernel. all is good in my world. i havent had 4g since last july/aug time frame. i havent missed it. in fact, i dont even connect to 3g when im out and about. too much battery killer. i wait till im some place with wifi to sync email and weather. yea, im upset that my phone is "broke" but i couldnt be happier with my rom/kernel mix. thanks all for the help. i figured id be the "ginny pig" and do some key trouble shooting. at least im back to hboot .76!
side note, i dont even have a tree.xml file!
Code:
$ ls -l data/misc/wimax
ls -l data/misc/wimax
drwxrwxrwx wimax wimax 2011-01-21 18:36 sockets

same here v01rider..
lost my wimax keys a long time ago, and, even though I am in Chicago, which is 4g heaven, I really dont miss it at all.
Have super fast wifi at home, and 3g is plenty fast when I am out and about, so, who really cares about it? Plus, if drains the life out of your battery like nothing else, so, once you try it out, and realize its not that big of a deal for a cell phone, most people I know never turn it on..

yeah, for awhile I toyed with the idea of unrooting, and going to Sprint and try to fight for a new phone, but, my phone works perfectly, I love trying different roms/kernels/themes, and, even though I too hope one day someone figures out a way to install new wimax/rsa keys, I decided it isnt important enough to risk getting a phone that isnt as perfect as my current one is.

correct. i put both phones on 1.47. then on the broken evo, i did a backup. verified keys were in the back up. copied the backup to my sdcard. restored that backup and now i have 4g again!

Interesting. So, you've proven that:
1) You can use a different phone's wimax keys, and
2) You can restore a nandroid backup from a different phone
On that second point, you wouldn't want to do that out of the box unless you were doing *exactly* what you wanted to do (replace your wimax keys with those from a different phone). Very cool.
Now, I wonder if you could have just taken the wimax.img from the different phone, replaced it with the wimax.img in a backup from your current phone, replaced the md5 entry in the md5sum file that is part of the backup, then restored that on your phone. If that worked, it would have saved you the time it took to downgrade.
EDIT: So, I take you just found a broken phone on ebay or something like that?
