Good way to backup WiMax RSA keys. Works before Rooting, and on stock OEM Roms. - Page 4

That would be why. In recovery it shows build 2.1.1. Can you point me to the latest?

Edit: Think I found it within rom manager

Maybe not amon's OP still says that 2.2.1 isnt available via ROM Manager but maybe he hasnt updated?
Just in case

ANYtime Bro.

Just got confirmation on the wimax restore.
If you use amon (and assume CWM) to create the wimax.img then in the event you lose your RSA keys you can restore it just like any other ROM restore via the restore function in recovery.
Still always good to know the manual techniques just in case.

thx for the info IKS....since both amon ra & clockwork now backup wimax & wimax.img contains the keys, I'm gonna unsticky....

Has anyone verfied Kouche's work? I.e. restored the keys and validated that they worked.

so there still no way just restore the key
cuz restoring the wimax.img restores radios as well

Just select wimax.

btw your RSA keys ARE in the wimax.img created with amon (and I assume CWM)

In amonRA's thread he lists the same manual restore method as listed here by using adb with the wimax.img on the root of the SD card.
Again, not challenging the OP but just thought a lot of users would find the wimax backup in recovery a simpler option.

Completely understand iknowsquat. When I originally wrote the post, there wasnt any recoveries backing up the keys at all, so I wanted to put something out there just in case.

There are ways to restore the keys if you used my method, but I am not 100% it should be mentioned. Likewise, I am not sure even mentioning using recovery to restore WiMax keys is "legal". The reason being is that it is essence exactly like cloning an ESN. It would be really simple to clone someones WiMax info to a "bad" phone and just use the thing as a wifi hotspot for 4G or what have you. If you are familiar with Linux command line, you can figure out how to write the keys back to your phone. There are several methods, but they usually involve using mtd-utils, cat, sed, and even dd.

But, for now, I am going to modify my original thread to point people to start using the new recoveries as this will be the simplest method going forward. If you have used my method, and need to restore your keys, you can use the new clockwork or Amon_ra recoveries in conjunction with the key dump you made. Again, I won't go into details because I dont want to possibly violate any forum rules about device cloning, but it can be done if you learn the following: cat, sed, dd, and mtd-utils. If you have a linux machine, just use the man pages on each of these commands and you can figure it out easily

Reading the Wimax Alpha thread on XDA by Shinzul, he states to be using Amon RA 1.8, or later, which I'm currently using Amon RA 1.8. When I do nandroids, I have a Wimax file created. Is everything I need in that file, or are the Wimax keys only backed up on the newer version of Amon Ra (2.X and greater)?
