Haha, to be honest, I doubt you'd ever get it to flash. If you somehow did get it to flash and actually work, you'd probably end up in a situation where only one person could connect at once. I've made all my nandroid backups with hboot 0.97. You wanna upgrade and try it? I'm game.

EDIT: FYI, though, I'm pretty sure the md5sum is determined based on hboot version and something to do with the specific phone. I doubt you'll get it to work. Of course, you've already lost your keys, so I guess you've got nothing to lose.

Lol, it's up to you. 0.97 is downgradable to .76 easily enough. I think at this point, you might need a new phone .

You do have insurance, though, right (or some backup plan or another)? I don't want to be responsible for making things worse .

haha, yea i have insurance. im not gonna use it unless my phone catches fire! if i dont get 4g working, its not the end of the world. ive been on cm6 with no 4g forever, i dont really miss it.

so i just tried this with my wimax.img

Code:
C:\android-sdk-windows\tools>fastboot flash /dev/mtd/mtd0 wimax.img
sending '/dev/mtd/mtd0' (12288 KB)... OKAY
writing '/dev/mtd/mtd0'... FAILED (remote: partition does not exist!)
and i have confirmed before that mtd0 is not a folder. im wondering since im on hardware 002 if the wimax is in a different place.

/dev/mtd/mtd0 is a (character) device. I don't think you can just write to it like that. From the shell (using adb or whatever you want), what do you see if you type:

ls -l /dev/mtd/

As a side note to this thread, I guess this issue should cause a person to pause before buying a used EVO on eBay, if they have to have 4G capability.

This is a good thought.



On another side note, not sure if this will help but I believe one could remedy the md5 mismatch issue with this command:

Code:
adb shell
# cd /sdcard/clockworkmod/backup/2010-06-29.20.22.53
# rm nandroid.md5
# md5sum *img > nandroid.md5

[Edit:] Arg, caught up with the rest of the thread and realized you are using RA. Not sure if the above could be used outside of Clockwork.

RA still has a nandroid.md5 file for each one, but I don't think that'll help. All that file is for is to make sure that nothing has changed since the backup was made. I think the problems comes in when the md5sum doesn't match what it used to calculate it in the first place. More than likely, it's using information from hboot, and some other stuff unique to the phone. When you try to restore, it needs to be able to calculate that md5sum. I don't think the problem ever was that the md5sum file didn't match the md5sums of the files.

Ok, so mtd0 is there, as expected. Presumably, you just need a nandroid backup made before whatever broke your wimax keys. Or, you're welcome to try one of my wimax.img files and see what else we can break .

good question. I think the more important question is, did you ever find a nandroid backup that actually has your keys?

You can't cd to a device . Honestly, I'm at a loss for other ideas. If you never had a good nandroid backup of your keys, I don't think you'll able to get them back.

have a look at this, apparently there is a new app to determine if the RSA keys are missing...

Having WiMax Issues With Your EVO? Check the RSA Keys | xda-developers

here's the direct link to the app thread on xda: [APP] WiMAX RSA Key Checker - xda-developers

Credit goes to kelmar for stumbling across this, and advising me of it

I've seen that before. Unless I'm missing something, it just tells you if you're screwed or not. I don't seen where it helps you restore your keys.

Yes, you are correct. This app doesn't get them back. Upon re-reading the first link, it does say "Getting them back can be complicated, but not impossible"

Haha, well maybe you heard the same stuff I've heard. I keep hearing now and again that it's supposedly possible to regenerate your RSA keys, but I have yet to actually hear of somebody who actually did it (or how they did it).

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.

Yeah, I'm afraid you might be right. I recall reading about that tree.xml thing, and I think it was used to fix a bad mac address (somehow changed by a radio flash). I don't think there will ever really be a way to regenerate actual lost keys, unfortunately.

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..

Yep, I think that about sums it up. I work in a 4g coverage area, and never turn it on. It would still be cool if we could ever find a solution to this, if one exists.

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.

Wait, so that is just the wimax.img from a different phone, and you want to try restoring it on your phone. Is that what you're saying?

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?
