this is a stab in the dark, but what if you made a nand backup WITH CLOCKWORKMOD, unrooted, updated radios and wimax, and then rerooted withunrevoked, and finally nand restore, keeping your wimax and radio the same.
just a question. somebody tell me why it will not work.

OR you could save yourself the trouble of going through all that work, use Amon_Ra's recovery (which backs up the wimax partitions without even telling you) and if your RSA keys somehow get hosed, restore the backup, which will also restore the working wimax partition.
i have heard many tales of people being screwed over by their backups not restoring correctly. i have actually answered my own question. i have looked at toasts root method again, which is unrevoked in a nutshell, and the pc36img.zip writes over the wimax partition. so i failed sorry.

So I have to return my phone cause one of my led flashes isnt working right so I'm going to run the ruu and return to stock for the return. my question is when I get my new one, after I root again can I restore my nandorid backup on the new phone without issues or is it not gonna work cause of different esn numbers etc?
Bleh, no one knows hehe?
I sure don't know, bunp!

Absolutely not. You will permanently overwrite your wimax keys, and risk messing many other things up. You cannot restore backups from different phones.
Titanium Backup, however, will work just fine for your apps. Just dont restore any system data, just apps only.

he could restore a nandroid backup as long as he doesn't backup wimax withvit. Then the wimax won't be touched, as long as he's using amon ra he can choose not to back up wimax and cache and recovery, just the other options boot, system, sdext, android secure and it shouldn't do any harm whatsoever. Only if wimax is backed up will it Bork the keys. I made just a back up of my wimax saved it to my pc and never back up wimax when I nandroid. Saves some space and keeps my wimax safe from being lost in case of a catastrophic SD failure, like the night I was bored in the hospital after a car accident, was all doped up on an iv of dilaudid and wiped my sdcard while I was flashing roms DOH! I felt like a retard when I went to flash from SD and it was blank lol. Luckily I had my tablet with my SD backup with me or I woulda been really bored with a dead phone.
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!
So here goes. I lost my RSA keys while flashing to a new rom and updating my radio, wimax, pri, etc. I didn't use the newest version of Clockwork, but instead 2.5.0.01 or something similar. I tried to update beforehand with Rom Manager, but it errored a few times. I did however backup my RSA keys to a text file using this method http://forum.xda-developers.com/showthread.php?t=887900
How can I restore them? I've searched and searched and read and searched and read. Tons of information on backing them up, ZERO information on using that backup that was said to be so important.
From what I understand, I should've backed up my wimax.img as well, but I don't think my old version of clockwork did that. Can that be replaced? Do the RSA keys just get added into the wimax.img somehow?
Any help would be greatly appreciated... especially since this is for a friends Evo, not mine!

I still don't understand why anyone would backup RSA Keys, use your own brains...
If you were wanting to test the WiMax feature for Cyanogen Mod ROM, I think you would backup your RSA Keys in case a trouble or problem occurs and it seems like most of the new players here on the EVO 4g phones are backing up their RSA Keys for no reason whatsoever... *Hence I have not backup my RSA Keys or done anything yet, and I still have a good phone thank god.
Ouch, maybe. I hope your issue gets resolved someway somehow, good luck, all I can say for you. ;/

I backed up my RSA keys because thats what i was told to do. Funny that on that entire RSA page it didn't say a word about backing up your wimax.img. Not to mention the OP has no clue how to restore the backups. Pretty much gave me a false sense of security. But I understand it's at my own risk.

+1 for that thought, most players of the EVO 4g playing around with the WiMax or RSA Keys should be extra careful.

Problem is, all I did was update his root with unrevoked3, wipe, flash a new rom, and update via the all in one radio/wimax/pri zip. Next thing I know 4g was gone and my rsa didn't check out correctly via adb. Been rooting/flashing evo's and epic's since day one and now all of a sudden we have this new problem? where was that problem before? i dont get it.
Why would anyone want to do a backup? To have it just incase something happens.
Too many people have lost their RSA keys from flashing. Why would you not want to have a backup? Once you lose your RSA keys, the only way (short of actually restoring the backup you made which no one has any idea how to do) is to return it to Sprint for a new phone.
And yes. I do agree it is pretty dumb that there is no restore method for the RSA backup.
So basically those RSA keys are useless?
Unrevoked has had a reputation for wiping 4g since the beginning. Did you ever do a backup with amon ra? If so you can use the wimax.img from that to restore the entire partition.

Never did an amon ra backup. Only a clockwork, and it was the older version of clockwork. The wimax.img would be it's own item inside the nandroid backup folder correct? It's not there.
Now, I know the RSA keys are matched with each phone, but how bout the WiMax image? Can I use another WiMax.img and just replace with the correct RSA keys?

I'm pretty sure there is much more to 4g then just the keys. You'll need your own certificates and everything. Toast our shinzul would be the ones to ask though, I'm not that familiar with the internal workings of 4g.

Kinda what I was afraid of. Not sure why people are pushing the backup of RSA keys if they're useless on their own. It's the wimax.img that is needed.
I'd like to complain and point fingers but I understand it's at my own risk.
So I have about 3 backups that look to be in tact but are corrupt. I have 5 backups that work fine.. yet none contain my working wimax key.. I don't suppose that hidden inside one of the corrupt img files would contain the wimax key? That is if it was backed up.. I used to use clockworkmod 3.0.0.5 I believe but i don't know if it ever backed up wimax.. I just hit backup.. With AMon I selected backup wimax one time by checking it yet my keys were already gone by then.. but seems you have to backup wimax manually with Amon.. First question I guess is does clockworkmod auto backup your wimax.. and 2nd.. can I extract the system.img or data.img .. one of those backup files to see if it's in there or is it just a lost cause? Thanks for any input.. Granted I don't live in 4g area, I've been pretty stubborn about getting the key back for those times I am in 4g area. Still can't believe I flubbed this up.. Thanks for any help at all on this..
Did you happen to rename the 3 backups that appear to be corrupted? If so, make sure there are no spaces or special characters in its name. Also, CWM used to auto backup wimax, but I haven't used it in quite a while so I can't say if it still does or not. Were all of your nandroids made with version 3.x.x.x? You can try flashing version 2.5.0.x and then attempt to restore the nandroids. The worst that could happen is a failed restore and you're already experiencing that. Give it a shot.

Yeah i know about the naming issue so I know it's not that.. In any of those backups there is no wimax.img either so I assumed it wasn't backed up. The only wimax.img I have is one that I've tried flashing several times and still produces no keys.. Thanks for the reply though
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?
Sent from my PC36100 using XDA App
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!
