Hey guys, I have had a problem recently devolop on my phone, regarding 4g. First, I will start by saying that I have read just about everything I can read regarding broken 4g, but find nothing pertaining to my specific issue. Secondly, is there anyone is the Las Vegas area having issues connecting to 4g? Next, here is quick run down of the issue. I use 4g daily, all the time. I have never had an issue with it. I am currently using Myn's warm two point two, RLS2, on kings #11. Never had an issue with 4g, no matter what ROM i've used actually. I have NEVER flashed a wimax update. I have flashed a radio update, maybe a month ago or so. So I was tethering while on 4g, and I downloaded a modified "sexy" rosy, with the browser button on it. I then booted to recovery, wiped cache and davlik, then flashed the rosie zip and rebooted. Everything seemed fine, rosie worked, and all was well. Then I went to turn on 4g, and it won't connect. Just says scanning, connecting to sprint, disconnected, scanning, connecting to sprint, disconnected. After trying a billion times, once I got it to connect, for about 10 seconds, i had great 4g signal (as i always did prior to this) then it kicked back to 3g, and was continuing its scanning loop. So i restored my nandroid backup (which I made right before I flashed that rosie zip, while 4g was working) and I still have the same problem. So, my question is, is it possible to screw up the RSA keys, having not even flashed a wimax radio update? Or am i just experiencing some insane coincidence, that this started happening immediately after flashing that rosie zip. I am not sure how much troubleshooting i should put into this, seeing as I dont see how its possible that flashing that zip could've screwed up my 4g RSA keys. I am not sure how to figure out if it's my phone or sprint's network that is the problem. I have read some threads on how to check if the RSA keys are still in tact, which I will probably try to test that later, but I have never used a command prompt, or ADB shell before. I guess it's time for to read up on that and learn how to do it. I get confused about if I'm supposed to be doing these commands from the phone or my PC. Does anyone have any opinions, suggestions, ideas, insight? Anything? Any pointers would be super appreciated. Thanks fellas.
Sounds like 4g network went down. Can't be anything else if you were able to actually connect even though it was only for a brief moment.

Thanks for the reply. That is certainly what I am hoping. I used root explorer to look at my MAC address, via data/misc/wimax and the number it provides me with matches the number under my battery, so I believe that is a good thing. One of the post's I read, regarding this issue, said to rename that number (xxxxxxx.tree.xml) to xxxxxxxx.tree.xml.old. I'm not exactly sure what that will do, or if I should try it. I am hesitant to play with things I dont know about (yet). Any further suggestions or opinions? If I were to call sprint, would they tell me if 4g was down in my area? We did have 4 straight days with some pretty insane and sporrattic lightning storms. Perhaps something got damaged.
thanks
So it turns out 4g is down near my house. I'm on 4g right now, just in a different part of town. Sorry for wasting the thread space. Thanks again

So I wanted to try out different kernels yesterday. I'm rooted using the Stock ROM.
My phone was already running netanarchy's 4.1.9.1 with no problems, but I wanted to try out King's kernel BFS #8 as well as #6. I did a cache and dalvik wipe prior to each flash. In the end, I deemed that I personally like netanarchy's kernels more, so I switched back to 4.1.9.1.
However, now my 4G keeps turning on and off. This is causing my phone to significantly lag in intervals correlating with the on and off of the 4G toggle. Is it possible that flashing different kernels somehow borked my wimax radio?
Any help is much appreciated.
Is it anything like I described here:

I'm having this issue and I never even rooted my phone. Note my latest reply that I did a hard reset on one of the evo's and now the 4g radio hangs on "turning on..." when I try to turn it on. Still seeing that now. Considering doing the unrevoked 3.2 to root it and try to fix it since sprint is clueless on the issue.
Yea, it is similar to your issue. I found your thread after I posted mine. I tried updating to the latest Wimax update found on XDA and that helped somewhat.
My 4G stays on, scans, and says connecting to Sprint network. However, it never successfully connects. I now believe I have the dreaded MAC address problem and am now trying to fix it.
I can't even see my 4G MAC address because I can't get the 4G radio to turn on. How else can I check whether my keys are screwed up (without being rooted)?
try dialing ##3282# and select view mode. Go to WiMax and look under NIA. That should have the MAC address.
If it does not match what is listed on your box, then your MAC addresses do not match.

You gotta be rooted to do that. As for your keys getting hammered, the key issue arises on rooted phones after a bad flash, or corrupted radio file. More than likely your keys are fine. Let me ask you this, have you previously have 4G working, and it just stopped working? Or you now just tried to use it, and it's not working?

Yes, it used to work. I picked up signal around the boston area a month or two ago (before boston officially had 4g). I can't remember whether I used 4g successfully after the 2.2 upgrade. I was part of the group that did the .3 leaked 2.2 update and then took the .3 to .6 update OTA. I have never rooted this phone.

There is no WiMax option when I do this. I think the WiMax radio needs to be switched on to see this. But I can't get the radio to turn on.
I've been using alogcat to try to debug the issue. I see this error come up about 90 seconds after trying to enable 4G (this is the same time the "turning on..." changes to "Unable to start 4g"):
E/WimaxStateTracker( 104): Failed to load Wimax driver -=>wl.release
I haven't been able to find any information about what this might mean.
same problem here; ever since running unrevoked 3 the other day, my evo 4g keeps turning 4G on and off by itself, and, wont let me stop it from doing that..
its killing my battery with its constant searching, and I cant find any sort of "tweak" that will allow me to just shut it off or leave it on; the widgets dont do it, so I cant figure out how to stop it..
was working fine before this..
On stock 2.2 froyo, stock kernel...
any ideas?
thanks!

Ok you may have hammered your 4G then. I've heard of a couple of people who took the leaked update, and fouled up their 4G. I would suggest you backup your stuff then run the latest RUU to see if that clears things up with the wimax driver not loading. If not take the phone to Sprint.

i read the thread you started about this issue. you mentioned you were having trouble breaking the on/off loop but then mentioned your wife somehow was able to do it. while in the on/off loop, did you find that the the radio was actually spending any time "scanning" after it turned on? on one of my evos, the phone would switch from on to off and back to on so quickly, the button was always grayed out in the wireless menu so i could never interrupt it. on my other evo, it would spend a little time scanning ( a second or 2), which was enough time to press the button so the 4g would turn off for good and break the on/off loop. a hard reset fixed the phone with the unbreakable loop (4g now works). a hard reset caused the other phone to change so that 4g just hangs at "turning on..." when i try to toggle it on.

By running the latest RUU, do you mean perform the latest OTA sprint update (the .6) by putting in on my SD card and doing the volume down/power button trick? Is this safe if I already have the update applied? I was considering doing this but wasn't sure if it would be safe to do.
So yesterday i updated my Radio and Wimax with Calkulin and all of a sudden i turn on 4G and it scans, connects, and scans. It usually just stays on scan.
My 4G MAC address is 00:16:08:00:24:05
I am currently running Fresh 3.3.
Help please ive been looking alllll day couldnt find anything.
same here
i got the exact problem and also running fresh. i tried updating wimax, radio, PRL, and profile and still scans then tries to connect and goes back to scanning
HELP........
NANDriod back
I hope you read the instructions and the posts in that thread.
I flashed mine and it worked fine.
I also ran across three instances of 4G problems when flashing "ROM's" and not the radio.
1.) Scans...scans...scans..and stays scanning. - Never connecting (I get 4G in my area).
2.) Scans...obtaining IP address...connecting to Sprint...connected!...disconnect...scans...
3.) Turn on 4G..scans...obtaining IP address...connecting to Sprint..connected..disconnected.. 4G "automatically" Turns off.
Luckily, I did a NAND back up prior to testing ROM's on Amon_Ra 1.80 so it backed up the WIMAX as well. I just NANDdroid back and I was fine.
Flashed teh ROM again with no problems. I can not determine the exact issue that occurred but it occurred.
Full wipe of everything.
SO....NANDROID back to your previous image!!! - That is your answer.
Okay thanks. Haven't tried that one
I'm gana do it right now
sent from my EVO
Still doesnt work
I Nand recovered my Damage Control Rom from before when 4G worked and i go back to turn it on it stays on scanning the whole time. I also did Titanium Backup from before but couldnt find out how to restore my back up from it.
I hope my 4G isnt broken
You know, I hear this a lot lately Radio/Problem/Fresh, just saying.
Try updating your PRL and Profile (Menu/System Updates/Update profile & Update PRL
Yea I hope they just make a solution to all this lol that would make it easier..

I tried it all and nothing works. I even did the unthinkable..... I un-rooted my evo.
Im bone stock 2.2 with latest update and I updated my firmware,prl,profile and still nothing. I'm gana go to a sprint store later on today to see what they say (need replacement anyways I just notice I got the volume and power crack button)
I'm frustrated that my friends and other people can get 4g and I can't. One of my friends is rooted and he has no problem. Hope that I get good news!

edit - if you're having mac issues, my note in the that thread won't help you...
Um i see the MAC of death(00:16:08:00:24:05) up there. Usually if you have that your wimax is fuked. Check your proper wimax mac under the battery cover and see if it matches. Also check and see if your cert keys are still there....i forget the command to check in adb shell. If no keys go get your phone replaced.

To check your 4G MAC address, you need to first have your 4G radio on.

Read that to check your RSA keys and troubleshoot whether or not you have hosed your keys. If you lost your RSA keys, then there is no way ATM to get it back short of returning your phone for a replacement.
Did you update your profile after flashing the new radios?

yea i always update my PRL and my Profile after flashing new radios but still same thing...i only just now found out there was a problem tho cus i don't use it too often and when i went to use it, it wouldn't stay on and scan for a signal.
sorry btw for the late reply
EDIT: would going back to a different WiMax radio version help? i would try it without asking but i'm afraid to ACTUALLY lose my RSA keys so yea.
I'm having the same exact issue...any updates?
I'm in the same boat. I had to take my day 1 EVO (hardware 0002) to a Sprint store on Christmas Eve as I dropped it flat on its face and shattered the screen last week. Although I figured it wouldn't be an issue, rather than risk a small chance that they wouldn't repair under the TEP and $500, I went ahead and unrooted and returned to S-ON and loaded the new stock RUU.
So that moved me from HBOOT .97 to the new 2.10 - I then used the handy root guide for 2.10 and was able to re-root and S-Off without any problem, but my 4G would not connect (it comes on, shows scanning, but won't connect). It did connect a couple of times, but then dropped and have not been able to reconnect at all. Wife has an Epic so know a strong 4G signal is working at home.
I've tried the tree.xml trick and also checked to make sure I still have RSA keys which I do (even backed them up after checking again today). I've reflashed the latest radios, updated profile and PRL numerous times. Nothing working. 4G worked perfectly before I unrooted, and after I unrooted (with stock RUU). It was only after re-rooting with the 2.10 thread that this happened. I have not flashed any recovery other than the modified Amon-Ra since the Hboot update.
Wondering if anyone has unrooted, then re-rooted and been able to reconnect to 4G. I may give it a try - just didn't want to go through the trouble again if it doesn't work.
Just an update if anyone else is having trouble with 4G. I had previously used Myn's rom and stock, but since Myn's wasn't updated for the new radios yet I just flashed the sprint lovers Rom in zikronix's 2.10 thread, then tried out Azreal 3.0 (which I really like) - it was in both those ROMs that 4G would not work for me.
I just flashed back to deodexed stock rooted zip of 3.70.651.1 and 4G works again!
First off, yes, I have used search and have read any thread where people said they could not get 4G to connect. I have used google to search for a solution as well. I am posting this with that hope that someone may have an insight and if I can resolve my issues hopefully others will be able to as well.
The Problem: My EVO will not connect to 4G service. It turns on, goes to scanning, connecting to sprint, authenticating to sprint, obtaining IP address, disconnecting, scanning, connecting to sprint, …
The History: I have always kept nandroids of pretty much everything I do on my EVO. I have nandroid backups from the first time I rooted my phone still hanging around. I have used nothing but AMon-Ra 1.8 and later recoveries and made sure that the wimax partition was backed up. The week before last my EVO connected fine with 4G. Last week Myn updated to RLS5 and naturally I ran out and updated it. Unfortunately I don’t have 4G coverage (or 3G or 1x for that matter) where I live so I didn’t notice that my 4G stopped working until I got to Salt Lake City. I figured it must be something to do with the Wimax towers in the area so I wrote it off. I have had that happen in various places that didn’t have official Wimax roll-out yet. When I got to Seattle it was still doing the same thing, that is when I started to get concerned. So I sat in a parking lot where I knew there was great 4G coverage (my laptop has a wimax radio in it so I could see the good coverage from Sprint) and proceeded to roll back to a version that I know worked. No good, still no 4G connection. That is when I started digging through everything I could find.
The Troubleshooting process: First thing I thought was that maybe I had whacked my MAC address. So I ran to XDA forums, checked out the post on how to check if my MAC is still good. MAC address reported by fastboot oem wimaxrmac is the same as the one under my battery. Maybe I whacked my keys? Again, ran to XDA forums and found that I can run ‘cat /dev/mtd/mtd0 | grep RSA’ and see if my keys are there. Sure enough ----BEGIN RSA PRIVATE KEY---- and ----END RSA PRIVATE KEY---- is there. OK, it doesn’t seem to be the keys, but lets check to see if the keys that are there belong to me and my EVO. So again, back to XDA. This time I find a post that shows how to extract the RSA key and the device certificate and then run an MD5 sum to see if they belong together. It also shows how to look at the cert to make sure it belongs to your evo. Sure enough md5 checks out and the cert has my mac in it in the proper places. OK, lets check on the tree.xml file. Sure enough it has the right mac. OK, delete it like the instructions say. Now, I restart 4g, it creates a new xml file, but doesn’t connect. That’s ok, the guide says it likely wont. I update profile/prl, reboot, turn on 4g and no go again. Lets do the profile and prl again just for good measure, same result. Hmm, look there is another way to do the profile update. ##data#, data profile, menu->restore. The phone reboots and runs through all the provisioning steps. Still the same results. Once more, back to xda forums. This time I find a post about checking your wimax partitions with wimax_mtd. Well, wimax_mtd thinks its all good too.
By this time I am really confused and figure maybe I can unroot and apply the RUU to dump it back to default config. Now my phone is unrooted and STILL doesn’t have 4G access. After rooting the phone again and going back to another sense based rom I ran a tail on the sequansd.log file, again found by xda / google searches. Here is where I have no idea what is supposed to happen. Here is the tail of the log file. http://pastebin.com/f2jL4MVF and here is a catlog from another attempt. http://pastebin.com/sZ2BiM9g
Here is where it gets odd to me. I changed my realm to clearwire by using ##data#, wimax, realm, clearwire-wmx.net, reboot. Sure enough it connects and gets redirected to the clear.com site. I ran a tail of the sequansd.log file and get basically the exact same things as I got when I ran the tail while on the sprintpcs.com realm. http://pastebin.com/0EU7Qh86
This is where I am stuck right now. Thanks for reading this far and sorry for the novel. Hopefully I gave enough information that this can get resolved and maybe it will help others.
Call Sprint.
I have never had this problem last this long, but I have had problems connecting to 4g before. MikFroyo 4.2 and Myn rls4 both had connection issues but it was usually a simple reboot before it was fixed.
I honestly have no clue. If your Mac Addy is fine and your RSA keys are there, then this is seriously a conundrum.
I'd suggest dropping your phone off a 3 story building and getting a replacement. That's just me though.
I called Sprint and went through about 5 techs. They ended up saying they don't know what is going on and that they cant see any errors on the tower I am connecting to. They set up an appointment for me to go into a local store.

I've been seeing this problem for a few weeks now, with several different ROMs, including the original rooted stock ROM now. In nearly all of my recent calls, I get disconnected one or more times with the message "Call disconnected" and a "Dismiss" button. I'm thinking that this is because of my EVO and not the other side, since usually if they accidentally hang up or something the call just ends without a message box. As far as I can tell, I have good reception (at least according to the bars), and this is happening at home, where I've not had the problem before.
Does anyone know what could be causing this? My wife's EVO is not rooted, and she does not seem to be having this problem. But then again, I've not had the problem until fairly recently either. I've tried updating my profile and PRL with each new ROM, but it doesn't seem to have made a difference. Anyone have any suggestions as to how to stop this from happening?
Go into the settings menu andbupdate both your PRL and your profile. That *should* help with reception related issues.

Unfortunately, I've tried both of those things. I just did some testing today, and it seems that my phone is unable to stay connected during a phone call for more than five minutes before disconnecting, even if I don't touch the phone and just leave it sitting on a table.
Any other ideas? As far as I know, I haven't ever flashed my radio away from its default (2.15.00.11.19), and I'm currently using the leaked stock gingerbread ROM (build number 4.12.651.1 CL41771 release-keys and kernel 2.6.35.10-gaa602b7 [email protected] #1).
Maybe it's time to unroot and contact Sprint?
You can try downgrading from 2.15.00.11.19 to 2.15.00.09.01. You can download it from http://www.mediafire.com/file/jyedjkp1bm5amwm/EVO_Radio_2.15.00.09.01.zip
Afterwards, go into recovery, wipe cache & dalvik cache then flash the zip. You will be taken to the radio update screen and appear to hang. don't worry or get impatient. After it is finished, you will reboot into recovery and see the words "clearing cache" at the top of the screen. Simply select reboot and then you will boot to your homescreen. The initial boot will take a tad longer since it will be rebuilding the dalvik.
Hmm... I'm hesitant to downgrade my radio because my wife has an EVO with the same radio version number and hers doesn't have this problem. Granted, she is not rooted...
I understand. I've downgraded and upgraded everything several times for testing purposes and troubleshooting purposes and have never had a problem. The only hing about flashing radios is patience and not to pull the battery. Anyway, you can always call Sprint and see if they can troubleshoot it for you from their end.

I would contact sprint @ 877-809-6696 (advanced tech supp). Ask them to push a full reprovision to your device. See if that helps any. I was having issues when when on the airave, I was unable to receive incoming calls. This corrected it. I did try all the other steps listed above without any success.
This is interesting. I unrooted to test things out before calling Sprint, and the problem went away. I was able to stay connected for an hour (where before I couldn't last longer than 10-15 minutes). Yay, fixed, right? So, I rooted again and didn't install any ROMs or anything, just rooted, and the problem came back.
So, I have a solution, but I don't like it very much because it means I need to stay unrooted. Anyone have any idea why simply rooting the phone with Unrevoked 3 (and doing nothing else) could cause calls to disconnect? I'd love to be able to root again, but I can't deal with a phone that randomly disconnects all the time.
I am interested in this as well as I am rooted using unrevoked and get disconnected as well. I do find that it mainly happens though talking to people who have service on AT&T.. Quite wierd. All I hear is a beep then disconnected. This happens when I first place a call and it rings once or twice then beep, disconnected...
This may not be related to rooting. I'm still communicating with Sprint about this issue, and along they way they replaced my phone entirely, and the problem is still happening. Very frustrating, but it makes it very clear that the problem actually has nothing to do with the hardware. I'm pretty sure there is some network configuration problem on their end now. I'm waiting to root my new phone until this issue has been resolved. It is killing me!

So whats the final call on this ..?
Is it Rooting , Is it network .. i am too getting psyche with this .
I'm pretty sure it is not rooting. But I don't yet know for certain what it is. Sprint thought there might be something wrong with the antenna on my phone, but they had already replaced the phone, so I think that is unlikely. They gave me a femtocell range extender to use in my house. Basically, I plug it into my broadband connection, and it is like having a mini cell tower in my house, giving me a very strong connection. Sure enough, when connected to that, I haven't had any calls drop. However, my phone still sometimes doesn't connect to the femtocell and instead connects to some other tower for some reason. My wife's phone doesn't do this, so I still think there is something wrong with my phone. I may contact Sprint again about this. ...sigh...
What is your area some area evo don't work properly like on rahim yar khan in this time connection don't work properly some signal drop and some time up i sure after few day signal work properly then problems will be solve.
My phone EVO is doing this now as well. Has anyone heard/read a solution?

I am having the same issue, out of the blue. No problems up until a few days ago. I'm wondering if it is maybe an issue with a certain version of the Evo. I have a version 002. Thoughts?
Greg_99 any progress on what might be causing this issue?
