Re: Good way to backup WiMax RSA keys. Works before Rooting, and on stock OEM Roms.
 

leerage,
The guide you posted from XDA is the same guide I used to root my Evo after I saved my RSA keys. Its a very good rooting guide, and I highly recommend it!

Re: Good way to backup WiMax RSA keys. Works before Rooting, and on stock OEM Roms.
 

Definitely. The guide is pretty straight forward. When I got my Evo back in early December, there wasn't the method of backing up the RSA key (at least in the guide). Everything went smooth though and I got my Evo rooted. Just now backed up my RSA key and all is good.

Do you suggest making this copy before I do this?:

That tutorial has the instructions on how to copy the RSA key before rooting/NAND unlock. I would go ahead and do it when you start the process of rooting your phone. When I rooted mine, that wasn't in the tutorial... but I didn't have any issues.

Thanks OP. Now I guess the next logical question is how do we restore the keys from the backup?

It is a unique key to your phone. I'm not sure how you would come about it that you would need to restore it... but who knows. Maybe some freak accident flashing or updating a radio and it wiped out the 4G RSA key... you would be without 4G. It is easy to run the commands so why not do it?

It is pretty simple:

Evo + RSA Key = 4G

Evo w/ no RSA Key = No 4G

Im having issues and am in need of major help, neither command works for me on my rooted Evo. i have titanium backup which installed busybox for me.

However i get both sed not found and busybox not found when i try the commands in adb or from a terminal app.

Any help would be great bc i need to have my 4g rsa keys backed up. Thanks

This would only work with me when I removed the space between 'rsa' and 'OEM.key'

Thank you!

The rooted way worked great for me. Fast and easy, saved to PC and Dropbox
