Got up this morning and turned on (or tried to turn on) 4G via the widget. Nothing. Went to settings to try and activate, and 4G is greyed out, with "Turning on..." showing. Went to 4G settings, and everything is greyed out (with "Turning on..." showing).
Pulled the battery and brought back up, same problem.
Did a hard reset. When the phone came back up, first thing I did was to try Wimax. Have same issues.
Phone was updated to Froyo a couple of weeks ago and has been working great until this morning.
Any ideas? The thought of getting a refurb phone doesn't thrill me. In the past the refurb I received (not Evo, but others) were worse than the one I sent it.
Thanks,

Couple of questions.
Are you in a 4G market, or in a "testing" area?
Rooted, or Stock?
Try this.. Start 4G, while it is starting goto Settings, About Phone, Hardware Information. Copy down your MAC address for 4G. Shut the phone down, and remove the battery. Compare the address you wrote down to the one listed inside the battery tray. Do they match?
I'm in Dallas (established market)
Stock (never rooted)
Tried what you suggested. When I first went into settings, it showed the MAC as "unavailable". I powered down, removed the battery and copied down the Wixmx MAC, then turned on the phone.
Brought phone back up. Tried to activate Wimax, but apparently it never did. MAC shows "unavailable" (same as when WiFi or Bluetooth are off). Apparently, the Wimax radio isn't powering up?
Ok, I am at work so I am limited to doing stuff via my phone. But there is a post about checking your mac address xml file. Find that post, and follow that procedure to verify your mac address is borked.
Next is to check your RSA keys. You do that by using adb shell, remounting /system as read/write. Then typing in
grep RSA /dev/mtd/mtd0
You should get at the end of the listing RSA PRIVATE KEY BEGIN, and RSA PRIVATE KEY END. If you dont get that then your 4g keys are lost, and you will need to replace the phone.

Never rooted? Is stroll into Sprint and have them fix it.
I had the same problem once, although in my case it was 4G and WiFi. That was my fault though. If I remember, I hadn't properly cleared my caches between roms and flashed the newer radios twice. I just had to completely wipe and reflash to fix it. That's probably not your problem though. I guess my post isn't all that helpful. Sorry, and good luck.

I missed the stock/never rooted. Take the phone to Sprint, have them take a look at it..

I'm having the same problem, but I have a rooted EVO.
I've tried:
Wiping both caches twice, then reflashing the latest WiMAX radio
I verified the MAC address on the back on my phone matches the MAC address under hardware information on the phone
I verified I still have my RSA keys
I'm running the stock rooted ROM version 3.26.651.6. Does anyone have any other suggestion I could try to restore my WiMAX?
Try doing a profile update, failing that try a master reset (##786#).

I'd try doing a complete data wipe / factory reset. Reflash the rom. And check to make sure wimax doesn't work before trying to flash the wimax update. A lot of roms have the update already included. If you try flashing the radio twice it causes problems I believe.
Now it works in many areas in NYC, including my apartment in Inwood, Times Square, UWS, UES,..
But when the 4G signal is weak, the phone hesitates which one to use, 4G or 3G, and sometimes it won't decide, and get a "Data" error.

Huh.. I work over at 49th and AoA, and I don't get 4G...even outside.. You suck..
I partially solved my issue in another thread, but still cannot connect to 4g. I had initially thought my RSA key was gone, but was able to find it in an old nandroid and reflash it. KeyChecker now says my Key is Ok. I verified my MAC address is correct and have flashed the most recent wimax radio. I have also updated my profile and prl. However, I still cannot connect to 4G. I was in Minneapolis in a strong 4g area and turned on the 4g. It turns on, scans, says connecting to sprint, and then quickly returns back to scanning, finds sprint, tries to connect, then scans again. I tried this is multiple spots all over the city but still couldn't connect. I am running Fresh 3.5 with the stock kernel and have connected to 4g in the past prior to temporarily losing my keys. I have flashed different sense and aosp roms with the same result. Someone please help! I am stuck! I would like avoid unrooting if at all possible, but will if that is a last resort.
I would call Sprint tech support and see if they could do anything from their end. You can try changing kernels or flashing a rooted stock rom to see if the problem gets corrected. For a rooted stock rom, download this and flash from recovery after doing a full wipe. Make a nandroid backup of your current setup first.

OK, Sprint was no help. As of now, my wimax key is intact and Mac address correct. If I am on Fresh rom 3.5 and turn on 4g in a solid 4g area, it turns on, scans, finds Sprint, then disconnects, over and over, never really connecting. Any other Rom I have tried, both sense and aosp, 4g won't even turn on, it just gets stuck at "turning on". I have also tried different kernels. I don't know what else to do. I upgraded my radios and profiles, would downgrading do anything?

I'm experiencing the same problem as you. Every since yesterday afternoon, I can't connect to 4G. It scans...connecting to Sprint.....scanning..etc. I never lost my keys though.

Same exact thing here. Took me hours to figure it out but here's what I did..total pain in the arse! I basically updated radios in succession. I loaded an old Sprintlovers PC36IMG.zip that had all the old radios (pri 1.77). After that I updated radios again, pri 1.90. Loaded up my Dark EVO 2.2 ROM, made sure 4G was working. Then while in recovery I flashed Caulkins .zip with all of the newest radios, loaded CM7, loaded GAPPS and BAM...everything is working great....total pain and probably a lot of unnecessary steps, but it worked!
As an update, I ran wimax_ mtd in terminal and it ran through fine, everything passed and was OK, except next to "check firmware file" it says not match and next to "verify app fireware key" it says not match. Any ideas what that means?? Can you give me exact details with file links to how you fixed yours?

So my friend rooted his Evo with Unrevoked. I verified s-off.
He copied a PC36IMG onto his SD which turns out was some 2.1 rooted stock ROM. After doing that his phone could not make/receive calls/text or connect to 1x/3G/4G. Basically an expensive phone that has no phone functions. Everything else works (WiFi included). He flashed http://link.geekfor.me/rootedromzip onto his phone from http://forum.androidcentral.com/htc...vo-install-clockwork-recovery.html#post165998.
When I looked at it, he still did not have a custom recovery so I flashed Amon RA PC36IMG. Full factory wiped data/cache/dvalik. Flashed Synergy RC1. Phone still could not make/receive calls and was getting Error 16 when trying to call. Called Sprint and they reprovisioned phone and fixed calls and texting. Noticed his phone is stuck on 1x and cannot connect to 3G when my phone next to his works fine. Did not test 4G yet since I have poor 4G coverage in my area. Cannot update his profile - just sits there like something is happening but it never completes.
What are his options here? Is it a bad radio or something that we can fix? Can we flash a stock rooted ROM and regain 3G? Remember, no nandroid was made unfortunately.
I would try flashing the latest radios just to be sure. And tell your friend to always make a nandroid backup to avoid this problem in the future.
Well his first time flashing. I think he mistakenly thought the PC36IMG as a custom recovery but it was actually an entire ROM.
Didn't have a chance to nandroid. I'm instructing him how to update newest radio combo and seeing what happens.
Update: Flashed latest combo radio. Updated profile and PRL. Still stuck on 1x even after reboot. Is he hosed? Does Sprint have to do something on their end to fix his EVDO? 4G isn't working either by the way.
Update 2: Wimax Keys Checker - https://market.android.com/details?id=com.joeykrim.wimaxkeys says that RSA Key is present. Relieved that he didn't lose his RSA key. Just can't figure for the life of me why he can't connect to 3G or 4G. Not sure where to go from here? Maybe trying to flashing latest stock rooted RUU? http://forum.xda-developers.com/showthread.php?t=1110733
Bumping for some attention.
Hey, happened to me a couple of times, it will come back. Maybe wipe everything again, have you tried ##data# and entering msl key, wait... Have you updated his data profile in settings

Ok, was on the road when I had wife reply...lol.. When you rebooted the phone,did you wipe cache,and dalvik. Then try updating profile? It sounds weird,but has worked for me,without even updating profile. I have had no coverage before after flashing a Rom,also,did just that,and it came back. If rsa keys are present,that is good. If you would be kind enough to reply,whether fixed or not,would appreciate it,anyway,gonna move on...

Did he try updating his profile & prl
Sent from my criffvo
Updating profile and PRL doesn't work. It keeps attempting to update but it is never successful.
I haven't had a chance to get his phone to just try reflashing a new ROM or stock ROM to see what will happen though.
He says using ##data# and entering his MSL code and changing EVDO to automatic doesn't work either.

I would start over again ... wipe completely with Calkulin's "fomat all" zip and flash a rooted stock rom like xhausx. Once the phone boots up, call Sprint and have them walk you through provisioning everything. Once all is well, then move into whatever custom stuff he wants.

You took the words from my mouth!
Is he Flashing the RUU's or just running them through the computer? Normally, you sync your phone or through hBoot and then start the program, try flashing stock Froyo and then factory reset once flashed, it helps clear out traces of old roms etc. If you need anymore help feel free to ask, I would be more than happy!
I don't think it worked.
Calkulin's Format, flashed Odexed http://forum.xda-developers.com/showthread.php?t=1133379.
It showed 3G but I think it was misleading. Wiped and flashed to evodeck and it went back to showing 1x. My phone has 3G showing on evodeck next to his so he definitely has 3G coverage.
I guess it's just time to call Sprint for a re-provision? Does it have to be on a Sense ROM for them to reprovision?

you dont need Sprint to provision, just get your MSL code and do it your self plus I would do a search for people who may of had similar issues and see what they did. Now if that does not work then why dont you check what your network settings are.. See if its set to CDMA(Auto) I remember my Touch Pro I could of set it to 1x maybe something is getting stuck. I think its in ##3282 you check it and I also remember an app on the market called network that did it for you as well.
If that does not work then flash 3.70 radios and then a 3.70RUU and start from scratch.
He already tried ##data#. He can change his EVDO to automatic but it doesn't stay that way.
Alright I don't know how I fixed it but it's fixed.
Just cannot get 4G now. Wimax keys are present. It keeps scanning and cannot get connect. Previously could get 4G at these locations.
I am running EVO as donor/target phone, my is only 1x speed, no matter which rom I try
Synergery, Mik, Stock-Rooted, differ kernal, different PRL, check the data profile Automatic, Try restore but can not cat automatically update, still need to go qpst to update my profile. I have been working on this for two weeks. I went back to my orig phone, it show ev most of time, the speed is must faster than my evo. Searc all over from goole, still no luck, Anyone any idea to try

i know this post is somewhat old. but Making a back up wont take hardly and extra time! always always make one unless you have 100% reliable roms already backed up.
I am having problems getting my 4g to work correctly. I am rooted, running synergy RLS1 + godmode. I have checked my RSA keys, which are still in good condition, my mac address is still in tact, and I have the latest radio/pri/wimax/prl etc radios. I have tried updating profile after everything and still cannot get 4g to function where I know it works. Any other suggestions?
Have you tried making a nandroid backup of your current setup then flashing a stock rom (or restoring your stock backup, if you have one) and testing 4g again?
It could be a rom related issue - I've heard great things about Synergy, but haven't been on Sense for months, so I'm not familiar with the rom. If you're positive that your wimax is intact & you still can't connect, call Sprint & see if it's something on their end.

I will try that next. I have a nand backup made already but I am not always in an area where 4g is accessible. I should be this weekend so I will give that a shot.
Thanks!
well i'm on synergy as well and my 4g works i have an evo 4g on metropcs and i use clear internet (had to get my phone macid added as an additional device on my clear account) on my phone for 4g works just fine
I cannot connect to sprint 4g. My wimax RSA keys are good but I still cannot connect. Any ideas?
when you try to connect to 4g does it just keep saying that its trying to connect but nothing never happens? have you been flashing like anything lately?
yes. just flashed a pc36img update. It worked before but now 4g is gone. I flashed multiple roms recently but then I did an ruu update. It just keeps cycling. it sais that it is connecting to sprint then it drops. it does this over and over. I have rebooted.... still nothing. my wimax rsa keys are good but it still doesn't work.
sorry but im completley stumpted by your situatuion. only thing that comes to mind is restoring a nandroid back up with working 4g, have you tried that yet?
http://forum.xda-developers.com/showthread.php?t=936945&highlight.=rsa+keys. Try the method in that thread to restore your keys.
http://forum.xda-developers.com/showthread.php?t=1127250&highlight.=rsa+keys. This method seems easier then the other, hope you get your 4g working again.
Same thing was happening to me and found out for some reason, my wimax key was "incomplete." For some reason, Amon recovery was not fully backing up my keys.
What happened originally was for some reason my wimax keys got lost (radio update or something) and I tried to recover an old Among backup. It restored successfully and my wimax key was now present according to the checker app. However, I had the exact same connection issues you describe. I then tried to restore an old Clockwork backup I had made. After restoring that image, my 4g began connecting immediately. This lead me to investigate further. After examining both backup files, I found the wimax.img created in RA was only a 2mb file while the Clockwork wimax.img was over 12mb! From this, I concluded that my problem was an incomplete image file. Therefore, wimax keychecker says its there, but can't and doesn't verify its size. To this day, I don't know why my RA images are so small so I keep a few old Clockwork backups just in case.

Update your radios. Mainly just your "profile" and then reboot. After that try to turn Wimax on. Then manually scan for a connection under mobile networks>4G. You should be connected if you are in a wimax area. If not then...get a refurb?
