[Q] 4G turning on and off, slowing down phone - EVO 4G Q&A, Help & Troubleshooting

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:
http://forum.xda-developers.com/showthread.php?p=8052344
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.

[Q] 4G NOT WORKING! Help!

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.

is it possible??

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

Issues connecting to 4g

So idk what exactly is going on but last night I tried turning on my 4g and when it actually turned on it immediately turned back off...then I tried rebooting the phone and seeing if that helped but the same thing...then I tried doing a little research and I come to find that people have been losing their RSA keys and breaking their 4g...so I ran android ask and checked my wimax via adb and everything seemed as though it was there landing the right place (no errors) but I still have no 4g...now if I'm not mistaken I upgraded a few radios, including baseband and wimax, and I heard there have been connection issues with flashing those as well, but not "broken" 4g...so I'm just looking for a little direction I guess...I'm running Myn's warm rls4 rom and using netarchy 4.1.9.1 kernel (if the even matters) and when I go to check my 4g MAC address it says unavailable...can anyone point me in the right direction...I don't use 4g a lot cus I'm just outside of a 4g area but still, its the EVO "4G" and I would like to make sure it stays that way...if you know what I mean ;-)...any help is appreciated

To check your 4G MAC address, you need to first have your 4G radio on.
http://forum.xda-developers.com/showthread.php?p=9663192#post9663192
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!

The most common cause of this is something corrupt in your data profile. this is fixed by updating running a data profile update.
Sent from my PC36100 using Tapatalk
as the above poster says try updating your profile. if that doesnt work try wiping all data/factory restore and reflashing the rom and trying again. Also make sure you have the radios for your rom. Ie if on a 3.7 rom you should have the latest radios if on an earlier rom you may want to try the previous radios.
what method did you use to verify you still have RSA keys?
i recently i a prob w/ 4g after switching roms. i updated the profile like 4 times, went to a non 4g area, turned on 4g, let it settle, turned it off. later that day i went back to the 4g area, turned it on, and BAM! worked great. My exact problem w/ 4g was it went from scanning, to connecting w/ sprint, the authorizing (for s spilt second), and back to scanning and so forth, over and over. hope this helps....

[Q] 4G WiMAX not working

My 4G isn't working on any ROMs that have reported 4G as "working".
I haven't gone back to stock yet, which is my next step.
Has anyone else had this issue? How did you fix it (if you did) ?
But is there a danger with the Epic, like there is with the Evo of destroying your RSA keys?
Thanks!

No, Epic don't have RSA keys. Maybe 4G is down in your area. Sprint is working on 4G nationwide. Call and ask.
Do you BONSAI?
It's not. A few of my co-workers have Evo's, and their 4G works. Harrisburg, PA BTW.
I should have been more specific....when I enable the 4G radio, it says "On..." and then goes to disabled after about 15 - 20 seconds. The radio won't turn on.

Have you tried turning it on in settings instead of the top bar? You may have to Odin back to stock and see if it works there. If not then it is the perfect time to hit the Sprint store. Odin should work, one of your Wimax files might have gotten corrupted in an earlier flash. Everything you need is here:

I returned to stock EC05...no dice.
Even if I go into settings, to enable 4G it says:
Turning on...
But then it doesn't enable.
4G might be messed up. Could be time to hit the sprint store.
I wonder if something got shorted? I've noticed over the past few days that when I plugin / detach a USB cable in / charging cable that the phone will just up and reboot it self. Maybe something got fried?
When I go under settings to phone status, it tells me that the 4G MAC address is "unavailable". Is that normal?

You will only get an address when you connect to 4G. Sounds like the 4G radio died.
Try the EE03 modem. The 4G functionalities are reportedly improved.
I tried ee03 modem with the official Frito release and with the ee03 leak. Nothing. I'm going to try to hit up the sprint store tomorrow after I put stock rom and bootloader back on it

OK, I'm getting a similar problem. The WiMAX Radio turns on, but it never connects. I know for a fact that I get reception in my house, and I've tried in a Sprint Store when I was testing the Photon 4G. Still can't connect; more specifically it disconnects after attempting to obtain an IP address.
I have already tried messing the WiMAX Extension settings in ##3282#
I'm running SyndicateROM Frozen 1.2 | Genocide 2.0 Kernal | EG22 Modem.
Suggestions?
