Okay so I ,about a month ago, lost my WiMax RSA keys by trying to flash a test ROM.

After many trials, and errors and many people helping me I Finally found a way to get mine back.

It is actually a very simple method. I was originally not going to share this method because it does not seem many people have lost their RSA keys until today I realized I was wrong.

First off what you will need!

-YOU NEED AN OLD CWM BACKUP FROM WHEN YOU HAD WIMAX KEYS
-You need TWRP recovery flashed
and you will need a TWRP backup with Wimax AFTER it was broke.
-You need to download Notepad++

-Now for a litttle info
CWM DOES backup the wimax keys. (commonly mistaken)
TWRP and CWM use the SAME kind of backups and code. except twrp just saves them in win format.
Although CWM backs your keys up they provide NO way to restore them (although twrp does)

So what do we need to do?
-Convert CWM backup along with md5 for TWRP.



PRIOR TO THIS MAKE A NANDROID BACKUP WITH TWRP AND MAKE SURE YOU SELECT TO BACKUP WIMAX (i know it seems pointless to make a bad wimax backup...just do it...if you ONLY want to backup wimax and nothing else thats fine.

Estimated Completion time? About 10 min
Difficulty: If you can read,type,and click a mouse button your fine.

++++++++++++++++++++++++++++++++++++++++++++++++
First. put BOTH Backups in seperate folders on your desktop.

Now download Notepad++

Now in the CWM backup folder you will see a Md5 file....open that up in notepad++.....You will see it has about 4 rows of md5 checks and a name by each one.
Find the "WiMax" labeled on and copy that string of characters.

Now in your TWRP folder with the backup you made open up (in notepad++) "wimax.eemc.win.md5" and delete the string of character (not the label!) and replace it with the ones you copied.

Now go back to your cwm backup and rename your backup to exactly what it says in your twrp folder for wimax and just change the extension to ".win" (my twrp wimax was called "wimax.emmc.win" but it might be different for you) now with the renamed file (with new extension" delete the one we made with twrp (only the win file NOT the md5) and copy the .win we just made from cwm and copy it to twrp backup folder.

Now in twrp restore your backup but ONLY have it restore wimax.

I know one way some people loose them is to flash a zip that isn't intended for our phone and didn't look at the updater-script to see that it wipes different partittions ment for another phone, which happen to be the partition the wimax keys are on. A.k.a the superwipe.zip that is floating around the web.
There is also other ways to loose the keys, sometimes recoveries don't play nice and will delete them. That is why many guides say the first thing to do after rooting is to backup everything including your wimax keys. I do believe the shiftrr.exe even has the option to back them up.

Yup I lost my wimax keys flashing a test 3.5 ROM for newtoroot (way before the one he released) guess the updater script wiped it.
My biggest complaint is that even though cwm backs wimax keys up. It provides no way to restore it. I just never understood lol

You know the other day I was messing with WiMax on my laptop and I connected to Sprint and I thought about you and if I could export my Shift's WiMax key and get it on my laptop some how.
LOL
I doubt it. Each key are specific to a device. I remember people doing some crazy **** like buying a used evo to replace the chip and THEN transfer the WiMax keys, or something like that. But that's before I wrote this or they made absolutely no backup anywhere.
