Did you turn your 4g on first? You wont get a mac address unless it is on.

I also have the same problem. I went from CM6 to Fresh 3.2; i updated the radio and wimax radio and my 4G is stuck on "scanning" and says MAC address is unavailable

Take your phone to sprint. They will replace them. Just tell them your 4g is not connecting. As of right now I don't believe that there is a fix.

not true, he probably botched up his 4G while flashing somehow. The development section has a few dedicated threads with the necessary steps to fix a bad mac or broken 4G.
Also, the phone will not show a mac address until 4G actually connects

I had this same problem with my phone. I got a new phone, rooted it, and set it up on Fresh 3.1.0.2. Before I rooted my 4g worked fine. After flashing Fresh 3.1.0.2 it stopped. My MAC address still matched, but for some reason I could not get my phone to get passed scanning.
If you turn your 4g on, and let it try scanning you should eventually get a MAC address to show up. At least I did.
What I did to get it working again was I flashed the latest radios, and changed ROM's. I was on Fresh 3.1.0.2 and flashed up to 3.2, and all works well.
Also, make sure you know you are in a 4g area. I thought it was just me at first, but I tried some co-workers 4g and found that I wasn't getting 4g coverage in an area where I thought I had had it before. So just make sure that's not the problem.

4g WiMax Broken
So I live in area with 4g, worked perfect when i got phone, but then I went out of town for a month to area w/o 4g & rooted it, and have since flashed couple of different roms.
Now I'm back in 4g area and it doesn't work, and not sure when in rooting/flashing rom process it stopped working
I used simpleroot, and flashed burntdroid, then couple other roms I didn't like (virus, baked snack, maybe 1-2 others) now back to latest version of burnt. Before each rom flash I cleared all those things in recovery that they said to clear (devlik/user data?/some other stuff). I did flash kernel couple of times in between from one's on this site. I have never flashed a new radio, or wimax.
Did try turning on 4g like someone said, and then it does bring up correct wi-max mac address that matches one under my battery. But 4g does not show up at all on top of screen at all to show that it has connected.
I was going to try those procedures for ppl w/ broken 4g, but I never tried to flash a wimax radio, and my mac address seems to be correct, so not sure if I need to do that. What's wrong?? Should I flash a wimax radio?

ok so looking at some other threads trying to figure this out, looks like I may need to flash new radios.
Have some questions:
In one tutorial it says to flash newest radio BEFORE flashing new custom rom, any issue with me doing it now AFTER I have flashed custom rom?
Do I just take the latest radios from this thread: forum.xda-developers.com/showthread.php?t=715485 and put them on my sdcard, and boot into recovery and flash em??
Toast had a post saying to do that, but one step says "Reboot to recovery and run .sh or .bat file to gain custom recovery"
Is this just holding vol down and power to get to custom recovery? What is this run .sh or .bat stuff? Also what's the difference between Radio and NV one's listed on that site?

well flashed the newest radio and wimax (not NV cuz still couldn't figure out what exactly that was) and didn't brick anything and wimax mac is stil correct, but still no 4g when im in area that should be getting it!

I ended up wiping the fresh rom and flashed the evio one and now I have blazing fast 4G, maybe the fresh rom just has issues with 4G

Maybe just a clean wipe will do the trick... I flashed the newest ota and wiped everything and my 4g magically started working.

RSA KEYS are missing. Lost nand back up due to corrupted sd card and hardrive. Help

Hello XDA Community
This all happened when I wanted to update on myn rls5 New Rom and I flashed the radios, I had performed a nand backup on the phone it self prior to installing rom and flashing radios. In the middle of the processes my phone just froze and showed a small android out of a box icon, I tried removing the battery after 20 mins still no boot. Then I tried installing again, but my sd card was not visable, loaded up my card with adapter not visible on 5 pc's a nook and cam. It seemed it was curroppted, tried formatting with 5 diffrent programs no luck even in recovery menu. Now my phone would enter into recovery either. I then just flashed recovery from unrevoked website and i was able to install caulkins rom. It worked but no 4g. In the meanwhile i was able to send in my 16 micro sd card back to sandisk for a replacement. I had purchased it when it came out had 1 year left of warranty got it back yesterday it took a week. Now I was trying to install myn again and tried but the radio flashed again and booted still no 4g. I checked my rsa keys using joeyks?? app from market and it shows as rsa keys missing. I had backed up my nands on pc but my HP hard rive became corrupted and lost it. Just got replacement 2 days ago. Now I tried changing my mac address because it is different from back of phone and when turned on in system menu. It just says scanning, connecting and restarts scanning. I cannot get adb to install correctly again, i type adb devices and just shows list of devices, and nothing. I have a windows 7 64bit. Tried with htc sync drivers no luck now, others from xda forum no luck either. I have downloaded the sdk, java and open cmd promt correctly still no dice. Is there a fix if my rsa keys are gone and no image. Will changing my mac address as found here will help? http://forum.xda-developers.com/showthread.php?t=715525&highlight=rsa
Please help and thanks you in advance.

So, to summarize:
You had a bad radio flash, your RSA keys are gone, and all your backups are gone.
You are what we in the tech community like to call, boned. Really. Once your RSA keys are gone, your only hope is backups. If those backups are gone, you're screwed. Your only choices are as follows:
1) Live with no WiMax.
2) RUU your phone, take it into a Sprint store/repair center, and try to get them to replace your phone. It helps to actually know what RSA keys are, and if there was a recent OTA, as you can usually blame the OTA for your key loss.
If/when you get a new EVO, backup your WiMax RSA keys online. Dropbox is a great, free way to do this. Click here to sign up for Dropbox and get an exta 250MB for free.

I lost my keys and I loaded up a bad kernel lol so my cam wouldn't work and flashed back to stock rom. I had all this planned out and I said and ota messed up my cam. It was brilliant. I got a new phone in 2 days.

I need to do the same thing. Bad backups didnt save my keys. =(

*...backing up my keys now...*
EDIT: Also emailed them to myself..

Thanks, the problem is that I sanded the edges off my phone so it looks red, now I don't think they will take it like that. Im ganna have to claim a lost phone and get a refurbished one. Is there any hope of a fix soon maybe with the new cynagen? im currently using miui now because I couldn't find a fix. Its pretty darn good. But i miss my 4g. It sucks cause the myn room isnt that great anyway, i prefer caulkin. Oh well. Thanks

There's nothing to "fix". The data is unique to every phone, and can only be generated by Sprint (since a corresponding RSA public key has to be loaded into their system).
Like I said, your only choices are a new EVO, or to live without WiMax. Believe me, I know, it sucks. I lost my keys because of a bad WiMax radio update a few months ago. Fortunately, WiMax just came to my area a few weeks ago, and so when it did, I brought my phone in and got it replaced.

thanks, I guess ill give asurion a call.

[Q] 4G on... asking to tap to choose an antenna?!?!

I have been trying to resolve this, but could not find an answer yet.
I was very happy and satisfied until a week ago... every time I turn on the 4G, it will show the 4G icon with an ! next to it and when I drop down the taskbar I have to tap to find an antenna... it takes much longer to do it... and many times after a while, the icon shows up again and I have to click again to find an antenna. ANyone having this issue or know what to do?
I tried changing roms, reflashing the radios, but no luck...
thank you
edit: OOPSSS... sorry, posted in the development thread. I am so sorry... the problem still remains though...

First things first... this thread really belongs in Q&A. It has nothing to do with development. Mod please move.
What is your current setup? ROM, Kernel, etc? Have you checked your RSA keys?
Have you called Sprint to make sure there isn't an outage in your area? I'm assuming you are getting the "4G Antenna On" icon in the top left corner and when you pull down it says "Tap to Scan".
Use the RSA key checker method, its posted here in the forum. Also try some of the 4G connection fixes, you can find them a few pages back as well. However, I think the prudent thing to do would be to check with Sprint first.

I noticed the thread just after I posted. I really don't know how to move but will try.
I have tried the stock rom and many others, wiping everything, and still got the problem. I have another Evo and it works just fine, so its not an outage...
I will try the RSA that you mentioned. I have no idea what that is, but will look for it. Thanks.

I'm assuming you made backups before you went flash crazy lol. Have you tried restoring one of your backups?
Sorry I forgot we have an app to check RSA keys now. Last time I did it, I just went thru Terminal Emulator.

RSA Keys Cheker says it's all fine... don't know what to do now...

Shotty service in your area? Using a wimax enable kernel?

Again, some more information about your current setup would be very helpful.

No go yet. Tried all the suggestions and still get the icon with an !.
Ive tried different rooms too, but right now, i am on sprint stock deodexed, latest radios and pri, and yes, dalvik and all else were wiped...

You're using a wimax enable kernel?

All this icon is telling you is that 4G is on but you're not connected. It lets you "kickstart" the scan process, and it serves as a reminder that if you can't connect to 4G, you'd save battery by turning 4G off. It's not all that useful. But it's a feature of the last update (or maybe the previous one...I can't remember). There's no issue here.

[Q] 4G wont connect on MikG

Hey guys I just installed MikG after a full wipe. Ran Kings Wipe all .zip 1st to delete everything as I do between all flashes but I can't connect to 4G. When I turn on 4g it says connecting and then authenticating with sprint and then it disconnects and tries all over again and it will just stay in the loop till i turn the 4g off. Any ideas to make it work?
Thanks in advance

you probably lost your wimax keys. if you have a backup make sure you don't delete it.

I doubt I have a back up. Any ways to get them back w/o that. I've flashed many roms before and never had any problems. Maybe I was just lucky. Usually just back up my apps with Titanium.

Okay update. It says Scanning, then Connecting to Sprint, then Disconnected and then it starts that all over again. So yeah I probably lost my keys. Anyway to get them back w/o a back up.

I tried it and still I'm getting the same thing. It did say it was authenticating with Sprint 1 time but not again after that. I updated my PRL and Profile as well as it mentioned in one of the other posts in that thread.

Don't assume it's the keys -- post 5 in that thread linked above tells you how to check.
Unfortunately though, if it is the keys, you're basically screwed. If you care, take advantage of the open enrollment in TEP next month (if you don't already have it), and pay the $100 for a replacement. Generally if the keys are gone, they're gone for good. So I hope it turns out to be something else!

I actually had this problem before and it lasted about 3days to a week, and then it magically worked again. I'd assume your keys are fine. Give it a few days

Well (insert curss word here). Just ran the terminal command through the terminal emulator on my phone that was listed in post 5 of the linked thread and I'm missing the hidden keys line. Looks like it is the keys. Anyway if I unrooted my phone I could bring it back to Sprint and be like wtf or would they have a way to check? Also I have been paying for the stupid TEP program since the day I got my phone. I mean worst case i'll just go back to an AOSP rom and it won't matter but i would like the 4G option. So yeah, any ideas on unrooting and bringing it back to sprint and playing dumb? Or some magic way to bring my keys back.

Also do you think running the KingsMOD-FORMAT_ALL.ZIP could have deleted my keys. I remember it saying something about formatting the system.

idk,
but for your keys i've seen it said that there is a method to restore keys.
if i can find the thread here i'll post link

Unless someone's found a way recently, you can only restore your keys if you had a backup from beforehand. Without one, they're gone.
As for unrooting and trying to return it, you can always try playing dumb, but my understanding is that people don't just lose the keys if they aren't rooted. So the missing keys in and of themselves are going to tell them you were rooted.
BTW, AOSP roms like CM7 have 4G now too. Basically you just need to decide if it's worth $100 to you to have 4G working. Also consider resale value, if you care. Assuming you're honest and disclose it, your phone might not be worth as much without working 4G.
If you do replace it, be sure to back up the keys in the new one once it's rooted. Both Amon and clockwork have that option.

I thought I had lost my 4G when I first rooted my phone, but i recently unrooted and put it back on stock, 4g worked fine. rerooted and 4g works now, not sure how that fixed 4g but it did.

Thanks for all the info guys. I would unroot just to try it but im reading now that all these phones can't be rooted now because of some update. Is there a way to unroot and then gain root again with out any of the problems these new phones are giving? But also since my keys clearly are gone is that even worth trying?

Radios going bad??????

About once a day my mobile data (3g) goes out and doesn't come back no matter what I do.My phone is useless when it goes out. The only way I can get it back is do a nandroid restore (and sometimes that doesn't work). My question is, is it my radio going bad, or has anyone else had this problem? And if so, how did u correct it?
Edit: I guess I should have mentioned it happens when I'm either streaming netflix, or like in the middle of a download or something.
Edit #2: I've also realized I can still turn on 4G when I lose all data, but when i do lose it, nothing works, not sms or my phone.

What radios are you on?

Thanks for Ur reply: I'm on the newest radio 2.15.00.12.19 been using it since it was posted on caulkins thread. This problems been going on for a week now.

does this happen with any ROM or one specifically?

It's happened on 4 different roms now

rats! you try reflashing the radios again?

Not yet I haven't. I'll try that now.

Or try flashing a different radio if reflashing doesn't help. It could be that the radios you're using aren't the best option for you.
Edit: I don't think radios can "go bad", though.

weirdest thing happened to me today. I made two phone calls on my way to work. Went to call an 800# for my bank "signal lost" tried again same thing. I called back the person I was last talking to connected immediately. Retried my bank "signal lost" I was in traffic and wanted to know my balance so I nand restored and no problem connected. I'm not posting the ROM I was using cuz I don't think it was related it was just weird.
Anyway hope that radio is working for you I flashed the newest one a month or two ago. Seems good just can't wait till we get some LTE I'm about 20 miles south of Boston and 4G is non-existant. Drives me nuts.
