So I was looking at the information in this thread http://forum.xda-developers.com/showthread.php?t=936945 about manually restoring RSA keys to a template wimax file and it gave me an idea. Even though I did not have a dedicated backup for my wimax keys I might be able to find the in some other file on the clockwork backup I made after rooting.
Here was the process I went through:
1. Used unyaffs to extract all the files from the data.img made in the initial backup I made after rooting
2. In the misc\wimax folder that was extracted there was a file named <Wimax MAC address>.tree
3. Opened this file with notepad ++, searched to find Certificate, value that was listed under it beginning with MIID (was a long string of characters similar to described in the manual key restore post)
4. Then I ran a search on the same file for key, came up with another string of characters similar to those in the guide these ones beginning with MIIE. Further searching through the same file does show up some other listings under key, for my first try here I am using the first one I came to, if that does not work I will try any other ones that show up.
5. Using these to values converted to HEX I pretty much folowed the rest of the guide as written. Now when I run the Wimax key checker it at least says I have keys. I will have to wait till tomorrow when I can get back to a 4G service area and see if I can connect.
If anyone thinks this might not be a valid way to try and fix my lost wimax keys let me know. Figured since I already had lost 4G it couldn't hurt to try. I also apologize for this post being kind of long winded or if this is something that has already been attempted. After about a week of searching online for a solution to my issues I figured this info might be useful.
For some background information. I just recently rooted my 2.3 GB EVO using revolutionary. Among a few other problems I encountered was that I seemed to have lost my RSA keys even though first thing I did after installing the recovery was make a backup using the version of clockwork that is installed using the revolutionary method. While I have read that the newer versions of clockwork do backup the wimax keys I was never able to get them back by restoring my clockwork recovery. I have since moved on to RA since it seems to make the process much easier.
There is an app in Market called WiMAX key checker that would check to see if your keys are present. I would check that first to ensure they are indeed gone.
I ran the key checker a while ago and it told me they were gone along with performing any of the manual methods I could find to check for them through terminal or adb.
Hey there,
I hate to bring up a really old topic, but am at my wits end. I seem to have somehow lost my RSA keys trying to update my radio (last time I try that) and it seems that CWM did NOT backup my Wimax.img even though I made a full backup the only way I know how.
I tried this method and wanted to know the OPs results or if anyone else has had any luck. After I did this, I got the key checker to say I had keys, but NO 4G service.
Any thoughts? Any help since this topic first came to light a long time ago? Any help is much appreciated for this posting newbie, but longtime flash-a-holic.

Well hate to ask the obvious, but you're in a 4G area, it doesn't just say connecting? Do you have ANY other prior backups?
Hey teh roxxorz,
Thanks for the quick reply! I am in a 4G area. I used to get full bars and fast 4G. It goes through a weird loop of connecting, authenticating, disconnecting, etc. I got tired of trying and went to ICS, but finally wanted to see if any new fixes or thoughts had comes since I last tried and stumbled upon this thread.
Should I revert to a rooted RUU, flash the wimax.img file I made and see what happens? What are some experts thoughts? I was flashing the wimax.img on CM7 (backed up from when I had 4G).
4G issue might just be radio related. You have latest radios? wifi working?
Hey devnulldroid,
Thanks for the quick reply. Let me back up!
One day my 4G stopped working. Stuck in an endless loop after I flashed the newest radios. I used the WiMax key checker and it said I had no keys present. I freaked out. Flashed back to my last good nandroid, NO LUCK. I was bummed. I tried every possible fix, flash, etc to get it back.
Now I am here. Tried this method, but no luck. Trying to see if anyone has any suggestions as it appears the tree.xml file from my backup has keys and a certificate, but still won't work. Make sense?
To answer your question: I have working WiFi and latest radios. I am running a non-4G ROM currently, but flashed my last working 4G nandroid and tried this wimax.img fix and still no luck.
I hope I am making sense. I apologize if I'm confusing others besides myself.
I was able to pretty much get to the same point, 4g looping through scanning, turning off, and on. I haven't tried messing with it too much recently, kind of got sidetracked. I am pretty sure my wimax keys are somewhere, it just seems to be a matter of which hex strings go in what position, just haven't had the time to go through trial and error process to figure out which.
I lost my keys during a weekend long flashing Bender, all I did was flash a stock rom then went into sprint and said when I was updating my profile or prl my phone dropped and rebooted, now my 4g doesn't work. They gave me a replacement that I re rooted and made a back up of just wimax, it has come in real handy.

In you last backup, you should see a wiimx.img if you were using CWM, because it should backup everything by default.

Ok I have been hearing these stories about people ****ing up their 4G radios. I want to know if I am ok. I rooted my phone when it was at 3.29 and then I decided to go back to stock by running the RUU. Since the RUU completely wipes the device are my 4G keys gone as well? I have no way to check because I am not in a 4G zone (don't even have 3G . I can't use the SDK method either.
you are fine....
No you are fine. The problem comes with people that make a nandroid backup of their phone with AmonRA 1.8 (which backs up the keys) and then they try and restore that backup on another phone. It overwrites the keys and screws up your 4G radio.
You are fine - just don't use a backup from one phone on another one. They only way you can do it is by erasing the key backup then restoring.
If you use clockwork you have nothing to worry about since it does not back up the RSA keys for the 4G radio.
Hope that helps.
Thanks. Phew that has taken a load off of my mind.
That is not true. I didn't flash another update from another phone and I lost my RSA keys. Its from flashing WIMAX updates. I guess some DEV's went based on their phones and either erased their RSA keys so when it comes to us it is null or it writes their information onto our phones. Maybe that is why everyone ends up with the same damn MAC addresses.
You could quite possibly lost your RSA keys. You won't know for sure unless you turn your 4G on and go through a connection loop (not sure if it works in non 4G areas), your MAC address is listed as the one everyone is getting when you turn on 4G, or you go through the SDK ADB method. Either way, if you lost 4G, you won't be able to go in for service or insurance claims till 4G comes to your area. Unless you actually go to a Sprint store at a 4G City, you won't be able to do much.
yup sekigah84 is correct....
best way to check is to follow the instructions in this thread http://forum.xda-developers.com/showthread.php?t=797337
a little adb shell commands and you can find out.
Yes, but his question was with installing custom ROMS and going back to the original one. He said nothing about flashing new radios. That is why my response answered his question.
What you guys added is great extra info - but does not effect him as he was asking what happened when he wipes the phone - simple answer is nothing, unless he restores using a backup that has the RSA keys from another phone.
So again - no worries kid. Your wipe and reinstall of the ROM did nothing to wipe your phones RSA keys.

Touche. I misread along with your post that made me pass a brain fart. I apologize lol.
Although there is now a thread going around about Amon Ra not backing up RSA keys -.-
I hope to God it does cause I rather not have to root then unroot and then have to get a replacement from Sprint again.
To OP: Just don't flash WIMAX radio updates till its confirmed what is causing people to lose RSA keys and JUST IN CASE, use Amon RA and make a Nandroid Backup.

Indeed good call lol...but always good to check the adb commands and make sure he didnt mess something up in the process.
No prob guys. I wasnt trying to make a fuss, I just didnt want to confuse him. Thanks for all the input!
if I get a new phone hardware and I do a nandroid restore using clockwork mod from my old phone I shouldn't lose rsa keys because clockwork doesn't touch these, correct?
I dont think it does but you can check your nandroid file for a wimax.img
You should not restore a Nandroid between phones for a number of reasons, including the fact that some software's license binds it to a phone's serial number.
Just use Titanium Backup to restore apps and their data, and manually restore settings. Don't Nandroid between phones.
Would you trust an image of one windows system restored on another system - image of a dell on a hp? If the chipset is similar, it may work, but you will likely run into weird issues. Same thing here.
Set up from scratch is best. Backup along the way so you have some thing to fall back on when your tweaking fails. TB is very useful in this case.
If you do restore a backup from your old device, let us know how well your 4g works..
Don't listen to these people. I've done it and it works fine. Just make sure you remove the wimax.img before. And you'll have to change the htc folder inside of the nandroid to match the new phones serial.
I made the mistake of not removing the wimax.img. am now stuck using a friends
freeza, until they're comfortable with the technology, they really shouldn't nandroid between phones.
creyc, there's a lot of reasons you shouldn't flash nandroids between phones and until you understand and feel comfortable with what freeza said, just don't do it. If you lose those rsa keys you won't get them back. I highly suggest backing them up before you make an attempt at flashing nandroids between phones. There's guides posted that'll help you do that.
If it were me, I would backup the wimax partition from the new phone. I would search how to do that, and then doit.
That would allow a complete nandroid restore including wimax from the old phone-to the new, then a simple #flash wimax /sdcard/newsavedwimax (on the new phone)
Just saying..

I don't agree with this. There's other settings besides those in wimax.img that may cause conflicts. The kernel is part of the backup too, and depending on the level of tweaking, your new device may not support the settings that worked fine in the old phone. Finally, can you say with utmost certainty there no account related parameters (meid, etc) are stored in the backup?

If you are overclocking, you may want to remove SetCPU before the backup or even after through ADB, other than that, it is completely safe. I've been running on a nandroid from a previous backup since September, with updates to the software obviously, but essentially the same. I didn't feel like starting over, and I had over 200 apps that I would have had to redownload. Not to mention all the settings, tweaks, etc. I gave it a try and it worked out just fine.
I think the only thing besides the wimax partition you have to worry about, is the PRL/profile update. It will no longer work, because those contain the previous MEID/ESN in /data/data/ in a text file. A simple edit would fix it though, or even removing that text file will cause Android to create a new one upon reboot. Other than that, everything works fine. ESN/MEID information are contained somewhere in the radio and is completely different from any of the partitions that nandroid backs up/restores.
Good to know. I'll keep that in mind if I ever have the phone swapped. I may have 10-20 apps on here at best, so setting up from scratch isn't that big of a deal. Still a pain none the less.
Coming from a windows platform, at the end of the day, it's usually better to start over from scratch than to migrate an existing installation onto a new system... From what you describe, that isn't entirely applicable here though.

Yeah, for the most part I agree. But since Android phones are so simple in comparison to Windows and its registry, I figured "Why not?"
For the most part all you're doing is copying what's in /data to make your phone the way it was before anyway.
Since most, if not all of /system remains unchanged by phone specifics, you could really extract your system.img, make a "ROM" out of it, and have everything you had before, minus settings/etc.
/data is where things get interesting and is comparable to the Windows Registry. However, /data is so small in comparison, that most of the time, it's not a big deal to poke around in there.
Swype FC ring any bells? Why? Since the 3.70 adds Swype and its LIB into /system/lib instead of /data/data/, you get two instances of Swype's LIB, assuming you're installing the beta alongside your already included Swype. This leads to FC. All one would have to do is remove the lib in /system/lib, possibly Swype in /system/app to get their beta Swype working again.
Anyway, if anything were to not function correctly from restoring a nandroid from a different phone, all it would take is a look in /data/data, find the troublesome program, poke around in its folder, possibly clear its cache/cache folder, and maybe edit a text file inside of /data/data and you'd be fine.
Never restore from an old phone two a new phone you may brick it

So, say hypothetically...one didn't read this thread before he nandroid restored to his replacement EVO today. Well, at first it failed to restore the boot so he went in and individually restored each option besides boot and including wimax. He had no 3G before but 4G would wokr. Now he has no 3G/4G after going through and individually restoring each option, just 1X. He checked his RSA keys using WiMAX RSA Key Checker and the RSA key is present.
Is there still anything he could do to get back his 3G/4G if this hypothetical situation were to be true? RUU work maybe?

UPDATE: I used unrevoked's S-On tool and then did the most current RUU. I then updated PRI/Profile and then made a nandroid since 3G/4G was working. I then flashed CM7nightly23 and now I don't have 3G again. 4G is working and 1X when i cut it off? Any insight on this problem? Thanks

You're pretty much out of luck. Call Asurion and pony up the 100 bucks to get a replacement. Lesson learned.
The Wimax keys are you unique to each phone, and can't be recovered or "given" a new one. He'll have to claim it via insurance, pay the deductible, or live without 4G.
Well I thought I updated the post before y'all commented, but I did use unrevoked S-On and then did the latest RUU and booted up and everything was working. I then used unrevoked and I nanroid backup the stock ROM rooted. I wiped/data/cache and flashed CM7 nightly 23 and only have 4G and 1X now?

Yes, and i have toggled it a few times to check. I have also toggled data sync and stuff like that as well.
Ok,so i just recently climbed out from the rock i have been hidiing under and found out about rooting my Evo.I did the crap load of reading required before you do something like this and after trying it for 4 hours with some limited help from some friends on XBL and some chat forums i did it.I have rooted it and installed some 2point2 ROM that was recommend to me.Is there anything else i should know or do to unlock me Evos full potential?
Well being Nand unlocked...if you used unrevoked, flash unrevoked forever. Just read up on RUUs, incase oyu need to unroot.
http://forum.xda-developers.com/showthread.php?t=894880 Just for shows. And read up on roms and enjoy basically.
Yeah,i was told to use Unrevoked3 and that it had Unrevoked Forever included in it.And according to what i read,this 2point2 had really good reviews by current users so i went with that.I was just curious if there was more i needed to keep reading on or things that i may still need to do.Like losing my 4g,although 4g is not in my area yet well there be some way to get it to work when it does come into my area? and besides that 2point2 is there anything else anyone could suggest if i need to do something?
try going to the evo section of the forums and try the "rooting for dummies guide"
its what i did! XD
Aaron,I was looking in the Evo section but could not find that. Would you mind posting the link to that forum please.Its funny,After rooting my phone im all excited and treat it like a new phone.But anyway,yeah a little more directions please cause i couldnt find it.Thanks to all who have responded as well.
I would try flashing other Rom's. Use the one you are using for a couple days and then try another. Also, make sure you backup your RSA keys in case something happens.
Ok,now i am lost.What are those RSA keys? and am i trying out new roms to find one i like or because these go out? Sorry,i am new to all of this stuff.But on the bright side very intersted,lol.
rsa keys are like a wifi passcode, but for 4g. there is one rsa key for every evo, and in this way, if you lose them in a bad flash, you can never get them back and never access 4g again on that particular evo. to back them up, boot into amon ra's recovery, version 2.3. select backup/restore. then nand bakcup. then uncheck all the options but wimax. then back it up. finally, boot up. then mount ur sdcard, and navigate to /nandroid/serial#/dateInAWiredFormat/wimax.img. copy that wimax.img to a very safe place...
welcome to the root crew
Well after reading your post i did notice that my wi-fi is not working so i am to assume that the 4G is not either.Also with this 2point2 i received a wireless tether that does not shut off once i turn it on.I have to take the battery out to make it stop. So thats all kind of a bummer.Also i noticed i have a couple apps that i have never had before,like superuser,spare parts,Rosie settings,DSPManager,and a ROM Manager.What are all of these things? It seems that no matter how much i read,i can never find the answers.LOL i think i just need pictures.

Superuser is needed to grant permissions to apps that require root. When you run a root app like ShootMe or Rom Manager, you'll get a popup asking you to allow it - that's Superuser. Spare Parts is like an extra settings menu. Just browse through it. Rosie settings lets you customize your Sense launcher. I'm not sure what's in there because I haven't used Sense since I rooted. DSPManager is like an equalizer for all sound that comes through your phone. It's a neat concept but I don't use it. And Rom Manager is an app that works with Clockworkmod Recovery, which is probably what you're using. It allows you to download and install Roms within the app. You can also do backups & boot into recovery.

Need help fixing 4g. Dont know when it stopped working but I have tried other roms and no luck. I have updated the radio then the profile and then the prl, I rebooted and then did the wimax and profile and prl and deleted some wimax file like one of the post said to do. No luck at all
I then tried to unroot to see if sprint would swap it out. When I try to unroot it tells me my battery is less then 30% and the other ruus say they dont see my phone. I dont know how I rooted it but I think it was with unrevoked not sure.
4g says scanning then connecting and back to scanning thats it. I use mikrom 4.61 right now

Did you check your RSA keys with the app from the Market?
Is your battery less than 30%? If it is, plug it in. If you want to unroot, just dl the s-on zip, flash that, then place the PC36IMG.zip on the root of your SD Card and go to hboot and let it update.
I got it unrooted. I did the unrevoke on patch and tried like 5 zip files and one of them worked. So its stock but I don't think 4g is working yet ill know tomorrow when I goto work.
Now what is this thing from the market for? Never mind I looked it up. So if my key is lost what do I do then? Send it in?
And no I didn't have any backups

You should have to buy a new phone for being a moron. This is why every post about rooting reminds you to make a backup. You messed up live with the consequences. Sorry that is harsh, but this is preventable and all to common. People are way to over their heads messing with their phones like this. Now you will try to get your phone replaced and because of people like yourself replacement warrenties get more strict and costs go up. Sorry for the rant it just really annoys me that people keep ruining their phones because they are clueless.

Me? No I didn't. Everyone says to do a backup but when I found my backup it didn't help. Even the stock Rom didn't help. So if someone can tell me how to backup the wimax key that may help next time. But what I see is once its gone its gone, not even a backup will help. One thing I did learn is that I'm staying with mik's Rom lol.
I rooted my evo and now I see a wimax backup in the recovery. I have never seen that in the backup of the recovery before. But many things have changed so could it be something they added in down the road? I rooted the phone when it first came out. But now I see what you are talking about the backup. Maybe next time someone can fill me in on that and not be such a ass.

It's easiest to do with Amon-Ra recovery, which you can find out about installing if you do a search for Amon-Ra 2.3. When using Ra, go to backup, and just check "Wimax." It'll backup just your wimax. Now, just go into your nandroid folder on your sd and add a "-wimax_key"to the end of the file name so you can remember it, and then put that backup in multiple safe places.
Are you sure it's your phone that is having the issue? Sprint could just have an outage. I've had some janky 4g coverage lately.
If it is your phone, what recovery and version are you running? All the new recoveries backup the Wimax keys. It's not true that "once it is gone, it's gone." I imagine you ran Unrevoked to root it which installs Clockworkmod recovery, so your original nandroid backup should have the keys backedup already. In that case you'd just need to wipe and then restore the nandroid. Upon doing that, it will also restore your Wimax key. DL the Wimax key checker from the market as previously mentioned and verify your RSA (Wimax) key is present. You are good to go if so.

It'll backup just your wimax. Now, just go into your nandroid folder on your sd and add a "-wimax_key"to the end of the file name so you can remember it, and then put that backup in multiple safe places.
Are you sure it's your phone that is having the issue? Sprint could just have an outage. I've had some janky 4g coverage lately.
If it is your phone, what recovery and version are you running? All the new recoveries backup the Wimax keys. It's not true that "once it is gone, it's gone." I imagine you ran Unrevoked to root it which installs Clockworkmod recovery, so your original nandroid backup should have the keys backedup already. In that case you'd just need to wipe and then restore the nandroid. Upon doing that, it will also restore your Wimax key. DL the Wimax key checker from the market as previously mentioned and verify your RSA (Wimax) key is present. You are good to go if so.

Thanks for the info. It was the phone for sure and I must have had the very first recovery version because I never seen the wimax backup before. Now on my new phone I see the wimax and other things I can backup. So on this one I checked them all and did my backup So that must be why the backup I found didnt help me. I never thought about checking to see if the recovery had updates.
Somewhere along the lines, I lost my wimax keys and only realized it when I was in an area that actually has 4g (my hometown doesn't). I tried Flashing one my number of backups created in Amon 2.3 thinking I may have backed up the Wimax, but no luck, none of them had the backup. At one point, I remembered creating a backup using Clockwork, not sure which method. I found the backup in a Clockwork folder on my sd card and see there is a wimax image file that is over 12,000 kb in size. I was stoked thinking my keys were found! However, I recovered that ROM backup image through Rom Manager but Wimax checker says my keys are still missing?? Question is, if Clockwork created the wimax image, shouldn't the keys be there when I recover that backup? Is there anyway to see if that wimax image contains the keys? Someone please tell me there is hope! I have a feeling 4g will be coming to my area soon and don't want to have to lie to Sprint to get a new phone
I think if you have the actual key, there is a manual way to program them back into the device. Do you have the original key somewhere (AKA on box, etc.)
Follow the instructions here to check your wimax keys.
Ok, I looked manually at my sd card as well and see one of my nandroid backups also contains a wimax.img, but this one is only just over 2,000 kb. In both cases, restoring those backups didn't work. I will try the method you listed to see what I get. Should I do it from one of those images I backed up?
hmm.. curious... what version CWM are you using?
i'm thinking you might have to revert back to an older version like 2.6 or below to get it to work.

I followed the instructions listed and yielded results as they did. I got a firmware version and it listed my mac address. Now what? It says OK next to everything and doesn't show any signs of error. My Wimax tag passes, it reads the wimax partition ok,etc. says my firmware version is R4623-evo-kddi. I am wondering though, would my backups that have the wimax.img not be recover that portion since I have upgraded my wimax radio since those backups were made?? Perhaps downgrading my wimax radio to an earlier version would correct it? Help please!!!

Not sure what version I used when I created the backup. Are you suggesting restoring the image in an earlier version of CWM will get it to work?

Easy fix
Get your wimax.img the one that's larger, put it in the root of your sdcard, open terminal ( get one if you don't have it) gain root permission by typing su
Then type
flash_image wimax /sdcard/wimax.img
Then reboot
Ok, i tried this from terminal and it returned the following error:
mtd: not writing bad block at 0x00260000.
So, what the hell does that mean? A bad image or a bad part of my sd card? Thanks for all the help, I really appreciate it!
You have a bad memory block in your WiMAX partition,
3 options
First, continue to flash the img in terminal until success.
Second, give up and accept defeat understanding no mo fo gee.
Third, get another Evo
Ok, so for ****s and giggles, I did the said method only this time with the smaller 2000 kb wimax.img. It flashed fine, I rebooted, and now wimax keychecker says my key is there!! I wont be in a 4g area until next week to verify,but it should work now, correct? When I turn the 4g radio on, it says turning on and then scanning! Thanks for all the help, its much appreciated!
Sent from my Evo, with renewed 4g!
If key checker said good, your golden
so, let me get this straight. If I never nandroid backed up my phone w/ stock rom on it, shot a 3g only rom, my 4g wimax key could be gone and I'll never be able to get 4G again?
question still stands, but I found the backup the wimax rsa key thread and it seems by phone had its keys still intact
Flashing a 3g only Rom doesn't wipe your keys, making a backup then will still back them up.
OK, so tonight I was in Minneapolis and tried to connect to 4g but couldn't. I verified my wimax keys are in place but still won't connect. It says turning on, then scanning, then connecting to Sprint, tries to connect but then back to scanning, connecting to sprint, over and over. I updated profile and prl and tried again, but still won't connect. What's next to check?

Just to be clear, keychecker says my wimax keys are present, I have verified my mac address is correct and the 4g radio turns on. However, I know I was in a strong 4g area in Minneapolis but it wouldn't get past the connecting to sprint line. I am running Fresh Rom 3.5 and have flashed the most recent wimax radio, updated profile and prl. Any ideas? Please help!
Bump...;-)

wimax key
I lost my keys probably months ago I purchased 4 evos and still have one of the boxes.Its not mine I was curious if the wimax keys are specific to each phone or can I use a wimax key from another phone? Our is the box and wimax code completely useless?
thanks
