History :
Was running Fresh 3.2.00 and all was good.
Updated to 3.3.0.1 without wiping *as was instructed* and lost 4G connectivity
alltogether.
Did some investigation and found my 4G Mac to be hosed so after reading the forums I used the adb method to manually correct the mac address.
The correction was successful but 4G never came back and thanks to the knowledgeable people on this forum I narrowed it down to missing RSA keys.
I did have two nandroid backups from when the 4G was working but restoring either of them didnt solve the problem.
So, the new EVO is here (insurance) and its ready for rooting and I would love to avoid bricking my 4G again.
Please advise me on how to proceed:
1. I already found a thread on how to root the phone with stock 2.2
2. How do I take precautions - how do I backup the rsa keys as to not get into the
same situation again?
The new EVO's stats are the following:
Android version 2.2
Baseband version 2.15.00.07.28
Kernel version 2.6.32.15-g746f4f0
[email protected] #58
Build number 3.26.651.6 cl218634 release-keys
Software number 3.26.651.6
Browser version Webkit 3.1
PRI : 1.71_003
PRL: 60671
All help and feedback is much appreciated
What exactly is "loose" on the phone?

The "old" phone after the fresh rom update somehow lost its RSA authentication keys so
I was never able to connect - authenticate with sprint again for 4G connectivity.
when you make a nand backup using amon ra 1.8.0 it will save a wimax.img, this should keep your keys intact so if you lose them again flashing this file should restore them
After rooting your EVO, flash Amon Ra's custom recovery 1.8 and make a NAND back up.
The NAND copy an image of your rom+wimax partition will retain most everything.
If you ever run into a problem like losing your rsa keys for w/e reason then you can NAND back to the copied image.

So the correct sequence will be:
1. Root the phone
2. Flash Amon Ra's custom recovery 1.8 and make a NAND back up.
3. Install custom rom.
Am I correct ?
PS: By the way, which rooting process would you use for a stock EVO that already came with 2.2 ?

youre also going to want to keep a copy of that first nand on your computer or somewhere super safe so you never lose your backed up keys
you can use unrevoked 3.21 and you can set it to install amon ra as it roots and s-off your phone, i just went through exactly the same thing.
Thanks for the help !
I just installed Unrevoked - smooth ride-
Installeld Rom Manager (Clockwork) and used it to install AR 1.8 Recovery
Doing my first Nandroid backup now.
After that, I will give Fresh 3.3.1 a try.
Awesome!!!!
Everything worked
ROM installed, I already had the latest radio and wimax on the phone when it arrived...and guess what...I am posting this while waiting on my car at the wash...over 4G!!!!!

Assuming RSA Private Keys are stored in the wimax.img (from nanadroid backup), use ARMON RA to backup your keys, ClockWorkMod does NOT backup wimax.img.
Now, best advice, DONT DO THE SAME THING, i.e., do not flash radio, wimax, nv, etc., until we ALL have a better idea of the pro/cons. Albeit the cons are plenty at this point. Root/Nand-unlock, flash away, Roms, Themes, whatever else but these.
Also, don't just do a nandroid-backup, turn right around and do a nandroid-restore, make friggin sure your backup is good BEFORE you need it.
EVO on...
Thanks for the advice, ....and I did.
After installing clockwork/ Rom Manager the first thing I did was to set it to install
AR 1.8 as alternative recovery and immediately tested it and did a full nandroid backup.
I checked the backup and the wimax.img is there.
o n o!
so your saying i need a new EVO?
So this is probably a noob question, but I'm having problems finding a direct answer, so here it goes. I am interested in flashing Calkulin's newest combo pack for radio updates amongst other things and I need to know that if by some chance I lose my Wimax RSA keys, can I just restore my current nandroid back with working 4g, and fix everything? When I go into the folder for the back up, there is a file named wimax.HT05CHL02409 so I assume that is the file needed to restore them, but I am unsure.
I want to update everything because I am in the center of Philadelphia and still have poor 3g and 4g, so I am looking for some help with that. I am running CM7.0.3.1 by the way.
you will be able to restore them
you can use the wipe menu and make a backup of ur wimax keys. thats what i did. i also copied the backup to my pc in case my sd gets wasted. after u flash use the wimax key checker app from market to see if they are still present and then restore if there is an issue

Yea, all my nandroid back ups are copied to my laptop as well. So if I make a back up of the wimax using recovery, how would I got about restoring it?
i havent had to do that yet but if i were to do it I would just restore my wimax backup from recovery and then use the key checker to make sure everything is ok

I am using Clockworkmod 2.6.0.1 and I can't find any option to back up wimax, so I suppose this is where you tell me to switch to Amon RA 2.3, right?

Precisely.
Well I decided to switch ROMs and go to MikG 1.01 and ended up flashing everything at the same time with no problems. However, I still have yet to have problems with Clockworkmod, so I guess I will stick with it for now.
Through help on another thread, I was able to locate a wimax.img from a prior nandroid backup made with amon's recovery. I was also able to open terminal and flash it back to the system making the Wimax keychecker say my keys were now ok. Question is this. Why would directly flashing the wimax.img recover the key but when I tried nandroid restoring the whole folder, the keys still wouldn't be present even though the wimax.img was in the folder?
Also, someone please check your nandroid folders and let me know how large the wimax.img is. The one I got to flash successfully is just over 2,000kb. I also found an old clockwork recovery on my sd card with a backup that has a wimax image file of nearly 12,000kb! Restoring that backup still showed my keys missing with keychecker though. When I tried to directly flash the 12,000kb wimax file, i received a bad block error.
My problem is that even though my mac address checks out and keys are present, I still cannot connect to Sprint 4g, it scans and finds the service, but connects and disconnects repeatedly without ever making a good connection. Is there a way my keys show up but aren't correct? Does the radio version at the time of backup make a difference when you are trying to recover?

I am not 100pct sure about this but I thought only Amon had the proper ability to backup wimax keys and restore without a problem. I could be wrong since I was not a fan of Clockwork just for that reason. My Wimax backup is 12 megs
wimax for me are always 12000 if you are trying to restore with clockwork you need to select advanced restore so that it restores your wimax too,because clockwork backs up your wimax by default but doesnt restore on a normal restore just on advanced
Well, I think what the real question is though is just because keychecker says my rsa key is present, doesn't necessarily mean the whole thing is present? I appears my backup with the 2,000kb wimax.img may not complete? I will look for advanced restore in clockwork to see if that restores the image.
At some point I wiped my sd card (copied all files first to pc) and reformated it for ext 1 and ext 2. My guess is this occurred somewhere between having wimax keys and temporarily losing them. Would this have screwed something up with my wimax partition where the wimax was originally stored?
thats a good question, because i have 2 sd cards one partitioned and one that's not, and i have never tried restoring a partition back up on the non partition card and the other way around.
What are your thoughts on the actually size of the wimax.img and the fact that keychecker says the key is present??
why dont you try getting a stock rom like sprint lover and doing a full wipe with something like caulkins wipe all and flashing the rom to see if its your rom not playing well with your wimax. also where did you get your wimax backup from?
edit: better yet why dont you flash clockwork and do an advance restore from the one that has the 12000, then if your 4g gets fixed, go back to amon and reflash to what ever you have now, i would suggets that if 4g gets fixed you dont restore, instead redo everything from scratch and then back up

I got the 2,000kb wimax.img from one of my nandroid backup folders. Just this morning, I flashed the pc36100 sprint lovers rom and it said the keys were missing. Plus, the 4g wouldn't even turn on, it just stayed at turning on before finally saying unable to start 4g. The 4g doesn't work on any roms I have tried (currently on Fresh 3.5) I have tried Myns, Kings, CM7, and a couple others, to no avail.

Good info. Will it work if I just do an advanced restore of the wimax? Or do I need to advance restore the system and everything for it to work. I am currently on my favorite fresh 3.5 setup and just switched to Clockwork and was hoping I could just do the advanced wimax restore. Or will that backup no play nicely on it's own?
try alone first if it doenst work try the full backup
Here is the interesting part. I did the clockwork advanced restore and verified the wimax key was present on my current Fresh setup. I also refreshed the old Clockwork backup that contained the wimax originally and got the system up and running (It was Sprint lovers I believe) and verified the wimax key was present. I checked both of the backup folders and the wimax.img created in clockwork in both cases was about 12,000kb. I then switched recoveries back to amon and did a full backup (selected all options) of both the Fresh system and Sprint lovers. When I open up those nandroid files, the wimax.img is only about 2,000kb? So, either I am not backing up what I think I am, or these two recoveries back up wimax much differently resulting in various output file sizes. Can someone explain this?
Also if am running one of these with verified wimax key, then nandroid restore to another file that doesn't have the wimax.img backed up, will I still have the key in place left over from what I was running? I understand how all of this works relatively well, but this wimax stuff sure has been throwing me for a loop! Thanks again for all the help!
My 4G works, and my Amon Ra wimax.img is 12 mb (12000 kb). Perhaps you should try a fresh download and install Amon Ra again, then try only backing up wimax. I only used Clockwork to make a backup once, right after I rooted, and don't have it handy to check the size of that one if it even has a wimax.img. I originally backed up my wimax keys via terminal, it was about 4000kb if I remember correctly.
If you restore a backup made with AR that doesn't include wimax, your working 4G should remain intact.
But your situation is odd... so I can't guarantee that to be the case.
(from... Evo/MIUI/Tapatalk)
yeah you can restore,just make sue you dont select wimax, and yeah it sounds like your amon ra is bad, its should always be 12000. but good to hear you are up and running, remember always and remember to restore with the recovery you used to back up, and i would keep a copy of the working wimax backup on my pc for safe keeping
What I don't understand is why my wimax key checker says the keys are intact even after flashing the 2000 kilobytes wimax.img

You can download a PC36IMG of Amon Ra from my dropbox, here: http://db.tt/WP0beNa
Don't rename it - it's named PC36IMG.zip exactly (even if you can't see the .zip), which is what it needs to be named. Put it on the root of your SD card, then boot into the bootloader. It'll scan for the file then ask you to update. Agree with the volume up button, then when it finishes flashing, don't reboot when it asks you. Instead go into recovery and make a nandroid backup of only wimax. If you want, you can go ahead and backup the default options as well, but do them in a separate backup.
Reboot back into the rom and make sure that 4G is working properly, then check the size of the wimax.img file.
If it's still too small, then that's totally weird. Hope you get it figured out, though.
OK, I flashed the recovery and made a nandroid backup of the wimax. I then used file explorer to check the size and it still says 2.38 MB. Just to make sure, I then changed to clockwork and recovered a wimax image that was 11.88 MB and rebooted. I then changed recoveries back to amon again to make a nandroid backup of my recovered clockwork image. Again, the nandroid output image file was 2.3 MB!?!
Is there some other way to check the wimax size/files without doing a backup? I am so confused right now.
Sent from my PC36100 using XDA App
what version of amon ra are you using i suggest 2.3, and also as long as you have a working backup even if it is from clockworkmod your safe, you can always go back and forth between recoveries if you need to, and if you need to restore a nadroid, just uncheck wimax, that way you dont touch the one you have that is working
If I recover one wimax.img over another, wont the original get overwritten? If there were any errors in flashing either of the images, wouldn't it tell me?

I had my Evo (android 2.2) rooted with unrevoked forever but had to take it in to Sprint. I unrooted with the S-ON zip and then flashed the closest PC36IMG.zip that I could find on the forums. Finally, I did a factory restore and applied the OTA (3.70.651.1).
I've got the phone back now, but ever since the flash my 4G refuses to connect. I suspect I might have messed up my RSA keys.
I have a recent nandroid backup, but I'm afraid to restore it because the PC36IMG.zip updated my radios. My question is: is it safe to restore?
I'm aware that I'll have to re-root and install clockworkmod again.
I'm a long time reader, first time poster, and I appreciate your input
Heck, if you're able to re-root, it wont matter. Once you're S-OFF, simply reflash the radio, PRI, NV & WIMAX that you had before you unrooted and then restore your nandroid backup. You *should* be fine afterwards. By the way, the radios are independent of roms so it's not like your baseband, PRI, NV & HBOOT was backed up when you made your nandroid backup with the WIMAX being the only exception and that is if it was selected to be a part of the backup. Having said that, if you are not able to re-root then I would not attempt to restore a nandroid backup.

Alright, thanks! I won't be able to downgrade the hboot, but I'll give it a try nonetheless. I'm assuming that bricking the phone's unlikely as long as the downgrades themselves are successful. I'd just have to reinstall what I've got now if the backed up ROM is incompatible, right?
Edit: I've got the wimax.img in my nandroid backup
If you have the OTA, and its s-on as you said, you can't root it as of yet.

Do you know which OTA that was? I have a feeling that I didn't get the latest one, since I'm not on Gingerbread.
I did get some strange results after running Unrevoked - I have S-OFF but I get the red triangle/exclamation point when booting into recovery and I don't have root.
If you are S-Off then you just need to reflash the recovery. Once you do that you should be able to reload your nand backup.

It seems like you do not have a custom recovery flashed.
User ROMManager to install Amon or Clockwork.
As long as you are S-Off still, then you will be able to reboot into the recovery of your choice.(Didn't see you didn't have root)
Try rerunning UnrEVOked.

I've tried UnrEVOked three times, all to no avail. Still the same result.
And yeah, I tried ROMManager + Superuser from the Market but they didn't work. Definitely no root.
I figure that I should be able to push clockworkmod using fastboot from my computer. I'm having a bit of trouble tracking down the right recovery image though.

Ah that one got posted as I was typing... thanks for the upload. I'll try it now.
It worked! Thanks teh roxxorz. Now I'll go ahead and actually get superuser, install CWM, then restore the backup and hope for the best with 4G
Update: I'm done and everything works flawlessly. Including 4G. If anyone has the same question, I can tell you that it's definitely possible to restore to a nandroid backup, provided that the radios are reasonably close to the originals.
I ran wimax checker from the market and it tells me my rsa keys are missing. I don't have a backup of my stock rom. So my question is this. Is there any way to restore my RSA keys?? I'm on the newest hboot rooted with s-off. Now I don't remember what recovery I was using but I did wipe something that said wimax at one point. I am currently using amon-ra style. My 4g turns on it just never connects, I am running Alter Rom, http://forum.xda-developers.com/showthread.php?t=1550526, which is a stock ROM. But my 4g problems happens with sense or AOSP. I didn't have any 4g problems before I did the wimax format. I have flashed the mewest radio combo which got my 4g to turn off and on again but I still can not connect. Anybody have any ideas??? Thank you.
Do you have any nandroids at all, or did you ever select Wimax backup in them?
I have a nandroid of just Wimax just for this case.
No nandroids at all.......I'm SOL huh??
Sorry, I don't know any other way... Perhaps maybe a cwm backup from originally rooting and flashing amon ra? Could always flash back to cwn and restore that? Otherwise sorry.
I think you're kinda boned on this one bud. search all of your stuff for a backup and see if you can get your WIMAX keys out of it
