ok, so i backed up with this method, then i used a rom that broke my fg keys. so i have the oem_rsa.key file that is the appropriate size. Can the person who came up witrh this method please inform all of us how we can restore our 4g keys using the oem_rsa.key file?

OP, maybe you should post something on the OP stating that this is a waste of time and useless.

Backing up RSA keys won't do anything for you but save a file that is virtually useless. Until there is a way to restore them, don't waste your time people. It's just giving you a false sense of security.

I backed up my Wimax partition BEFORE performing root. I have a 12mb wimax.img file just waaaaaaiting to be restored.

How can I restore the wimax.img file using Amon-Ra???

DOES ANYONE KNOW HOW TO RESTORE THE WIMAX PARTITION?!? NOT THE .KEY FILES, THE PARTITION.
[EVO 4G Q&A, Help & Troubleshooting] snovvman:
I am no authority, but you can try the following. I gathered this information from various posts. I take no credit.

1) Put wimax.img in the root of your SD for easy access

2) The key command is "flash_image recovery /sdcard/wimax.img"

3) You should do this in recovery (RA or CW), use ADB.

4) Enter command at ADB Shell: "mount -a"

5) Enter command from #2

6) Enter "reboot recovery"

Good luck.

Edit: I really feel for the people who did the key backup and are now stuck. I wish I have a solution for you...

So I just went with my friend (who I helped in losing his 4G service by doing what this post said but not backing up the actual wimax.img, thanks for nothing by the way) and the service tech said the mac address had been changed and therefo the phone software had been modded. We flashed back to stock and s-on but is there a way to correct the mac address?
[EVO 4G Q&A, Help & Troubleshooting] xHausx:
you have to be rooted to change it, you may be able to try at a different sprint store as long as they didn't flag your account. You could also just play dumb and say it quite working when you upgraded. Theres no way to prove it either way unless you left a ROM or something on your memory card
[EVO 4G Q&A, Help & Troubleshooting] jirafabo:
Yeah I made sure to delete all evidence from the sd prior to taking it in. We did play dumb and blame it on the update but the tech guy was just as good at playing dumb. He said he read in the sprint tech forum that if the mac address was bad then the phone was modded and they can't replace it. When I questioned anything he just kinda mumbled and bumbled and said to replace it through insurance. His whole conversation was kind of pathetic as he really cold only speak one line to every question we had, but I guess in the ed he wins bc he was correct.

The easiest way for me was just to use clockwork mod. Joeykrim just made an RSA Key Checker.

1. First check to see if you have your RSA Keys, search Joeykrim in the market. Very simple and easy to use, self explanitory.

2. Make sure you have the latest ClockworkMod, and make a nandroid backup.

3. Mound your sd card, look in clockworkmod --> backup, and double click your latest backup.

And inside you should see "wimax.Ht......" . Just copy and paste that somewhere safe and you should be all set.

[EVO 4G Q&A, Help & Troubleshooting] PolarWind:
I've seen several times in this thread people mentioning Clockwork or Clockworkmod.

What exactly is that? Where can I find it/info on it?
[EVO 4G Q&A, Help & Troubleshooting] gpz1100:
Its nothing more than a custom recovery or program that replaces the factory recovery.

What is a recovery?

It's a front end/scripts that perform device backup/restore, flashing of zip files/radios/etc.

Really I don't understand this bizarre naming structure. Why not just call it a backup/restore program, or maybe more accurately, an imaging utility.

Somewhere along the lines, the term nandroid came to be. It's used as a noun and a verb. A nandroid is an image or backup of your device's memory (not including the sd card in most cases). As a verb, it means to perform the backup.

These android developers are strange individuals!!!

You can find more info on it by using google, or searching on here!

I ran the "WiMAX Key Checker" app from the market and it tells me I'm missing my keys.

So I came here, found this thread, and created the rsa_OEM.key backup file, and it 3,734KB in size.

Opening it in a text editor shows that the file has contents that look like the keys to me. (two large blocks of characters at the top with quite a bit of white space after them).

If I "grep RSA /dev/mtd/mtd0", I do get several hits showing lines with RSA in them.

So why is my .key file smaller than what everyone else is reporting? If I run the backup command against any of my old nandroid backups to compare, they all produce a file that's the exact same size: 3,734KB.

Also, the wimax.img file in all my nandroid backups, including one I just now made, is 12,288KB.

Am I okay or not?

I tried both commands and got not found errors, I have titanium backup with busybox. I was able to do the cmd that backed up the entire wimax image. Do I need to be in recovery to do this?

And has anyone confirmed that you can restore your wimax keys from a nandroid backup with the latest clockwork mod recovery? I just did the unrevoked3 today and I have done a nandroid backup. I have not added a custom ROM yet and my 4g is working.

I need to know before I start flashing roms if clockwork will restore it or if I should just go ahead and put amon_ra receovery on my phone.

Thanks

So I tried the busybox sed cmd from connectbot from my phone and I got busyboy not found but I have downloaded it through Titanium bakcup twice now.

Even though I installed busybox from inside titanium, I decided to install it from the market place. Did connectbot and the cmd worked but the file showed a file size of 0. So I tried the cmd prompt from the computer and it worked and it has the correct file size. So now I have the rsa.key and the wimax.img backed up plus my nandroid backup from clockword mod. Hopefully this will fully protect my wimax keys, I am just trying to decide if clockword or amen_ra is better in general and for restoring from a nandroid bakup and putting wimax image back with keys in place.

[EVO 4G Q&A, Help & Troubleshooting] :
The thread title really should be changed to reflect the fact that though you can save just the RSA key, there are no instructions to restore that key.

To backup a working wimax partition, a nandroid should be made of the wimax.img and then to restore just restore your nandroid with only the wimax.img present.

7. If you do indeed have a # then proceed by running the following command. Please type it exactly as you see it. If you are familiar with Linux command strings, this will look familiar.

Code:

busybox sed -n '/BEGIN CERTIFICATE/,$p' /dev/mtd/mtd0 > /sdcard/rsa_OEM.key

Ok so im rooted and i pasted in the command for step 7, and i get a message saying permisson denied. When i go into file manager to check for my rsa keys its there but when i check the details it says its 0kb. Ive been trying for half an hour with the same results and my 4g works.

edit: after doing some digging through my sd ive found my rsa key backup and its not 0kb but around 4500kb. i backed it up prior to my 4g going out a while ago before i brought it into sprint, keep in mind its the same evo. they just flashed new software and all of a sudden it workd, so i cancelled the replacement they ordered me. so what id like to know how do i tell if its tied to my evo if theres any way to. only info that i can find thats matches is the "persist.wimax.0.MAC" its the same exact #'s when i turn on my 4g.

2. How to decrease the MIUI lockscreen wake up delay? There is a lag of about 1 second when the screen is turned on.

3. I don't want the opacity of the MIUI lockscreen wallpaper. Can somebody tell me how to decrease opacity so that the background wallpaper is visible clearly?

4. During an incoming call, the ring is almost immediate but the screen is turned on after 2 or 3 seconds. I have to wait 3 or more seconds for the screen to turn on to see who's calling. In other builds I tried this is immediate. Is there a solution for this?

5. During an actual call, after the phone is moved away from face, there is a lag of 2 or 3 seconds to return back from blank screen. Is this the problem of proximity sensor or g sensor or something like that? Is there a solution for this?

By having a2sd or a2sd+, does that drain the battery much more then just having all the apps on the internal NAND/Flash no SD used for apps?
