[Q] 4-g - EVO 4G Q&A, Help & Troubleshooting

I have tried several different Roms that have working 4-g coverage, Every rom in try when i try to connect to 4g it tells me its scanning but wont connect, I have updated all radio wimax pri and nv, i still get the same thing says it is scanning for 4-g but wont connect. my wife has 4-g shift and 4-g connects fine in my house. 3-g works fine but no 4-g, can anybody help me with this issue.

In the market download Wimax key checker to see if you still have your keys

Yeah it sounds like you lost your Wimax key
But hopefully you backed up your Wimax like every tutorial advised you lol

Or maybe your not in range of 4g or you don't have 4g service. Or possiblity Sprint tower is down. You have to look at those list and if everything fails unroot restore.back to factory setting see if your 4g works if not maybe you need to exchange it for new EVO cause it could be the hardware who knows.

Mattykinsx, steered you right, I followed the procedure in that thread and have since been extremely pleased with my 4g service. Of course as they say "ymmv", but it did work for me.
don't forget to wipe..

evo 4g wont go past "obtaining ip address from sprint"

i live in the middle of a good 4g spot and used to be able to connect with no real problems until i started rooting and stuff, now it wont go past the "obtaining ip address from sprint" step. ive tried most of the fixes with out avail but it didnt really matter to me since i never really leave the house except to go to work, but id like to get it fixed already cuz its annoying having only an evo 3g. im a modest user, not a noob but not an all out hacker.
details:
rooted+nanded via simple root 123, dc 3.2.3, netarchy-toastmod kernel 3.2.7a, mac address matches box, latest radio and wimax with updated profile and prl
Where do you live? Did this just happen. I live in queens NY and i was getting great 4g until last night when it just started getting stuck at obtaining ip as well. I'm hoping it has something to do with the signal.

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
Sent from my EVO using XDA App
Maybe just a clean wipe will do the trick... I flashed the newest ota and wiped everything and my 4g magically started working.

question

I have the phone for maybe 1 day I got it yesterday......I tried to use simple root to root my phone.....It was supposedly successful then i tried quickboot and it said i do not have root access.....Ive decided not to root my phone it seems complicated so i left it alone after this........I ran the gingerbread update from sprint this morning......My 4g antenna is on but it always has asterisks....Is there some way I can make sure i did not damage my phone?
If you ran the gb update you're not rooted nor did you damage your phone. Trying to use simple root wouldn't damage your phone either. Maybe just reboot, its possible you aren't near a 4G connection at the moment. 4G is almost like wifi, you can turn it on but if it can't connect it will just sit there. Last, what's with all the periods in your paragraph lol.
my period key is jammed on my keyboard. Is there any way i can get google video on my phone. I download vtok but it give off choppy video. My 4g has a ! next to it. Everything is ok right? How do i remove alot of the bloatware that is on my phone?

Because you're on Gingerbread you're going to have to wait to remove bloatware. There's no root exploit for it yet.
Don't worry about the ! next to your 4G symbol. That means the antenna is on, basically. If you're not in a 4G coverage area you won't see the other symbol that indicates you're connected to 4G.
try this: go into your Phone's menu setting and choose "Wireless & Networks." Look for the setting for "4G." Unless it says "connected to Sprint" you are not connected (probably because you are not in a 4G area).

If you aren't rooted you can't remove bloatware. Google video isn't on sense 1.0 I've only seen it on GB aosp roms (like nexus s) not a sense rom. As far as an exclamation mark being next to your 4G I've never heard of that, try turning it off I guess maybe the antenna is just on. The sucky part is if you excepted the GB update you can't root yet because devs haven't figured out how to unlock the bootloader. Sorry man
I am in an area in my office i had 4g yesterday with no exclamation point next to 4g.......I tried rebooting my phone whats up?

Maybe 4G is down, or towers having issues idk. If you want to feel better just reset and wipe the entire phone. Go to settings, and its either under applications or something else I forgot. It will say wipe everything from phone. I think its under "phone and SD card". Also try going to system updates and update your profile and prl.
i updated prl and profile and still exclamation mark next to 4g is everything ok?

Everything is fine. 4g is pretty fickle. You won't necessairly get a signal in the same place if its a weak signal.
Just don't worry about it. It will be there when you have a strong signal from the tower. Weather, buildings, even cars and people traveling between you and the tower can cause a signal drop.
So, when you see the ! Just wait until you get a signal or turn the 4g antenna off to save battery life. I rarely use 4g because of that.

I mean are u sure u are in a 4G area? If 4G is on and there is no signal to connect with that is what u get. What area r u in when u are trying to use it. Did u connect before u fooled with it?

is this for real? Turn off your 4g, its scanning and not connecting because you are out of range.

What is this and why am i Hungover???

I' some what confused with why my phone is doing this.
I've flashed many roms and i always wipe everything down and never had an issue.
but for some reason, after flashing deck 1.3 stable and tiamat 3.3.7, it stopped connecting to 4g.
i flashed the latest radio and nothing.
just reflashed sense and updated prl and profile and still not connecting to 4g
it shows scanning for 4 seconds, then shows connecting to sprint for 1 second, then disconnecting, then back to scanning. I just don't get it.
any ideas? suggestions?
thanks fellas.
sounds like your rsa keys maybe missing. try restoring a nandroid backup of when your 4g was still working that may do the trick if not check out this thread. http://forum.xda-developers.com/showthread.php?t=887900&highlight=rsa+keys. i forgot theres a app in the market you can use its called wimax rsa key checker or something like that. if it says your keys are gone just return your phone back to stock and bring it in just remember to play dumb when you do. just tell them all of a sudden your 4g stopped working.
check it out

damn that sucks. like i said earlier just unroot and put back a stock rom, then bring it in to sprint and play dumb. if they cant solve the problem then most likely they'll order you a replacement phone. once you get your phone back try to use 4g again some how after they flashed new software for me my 4g was working again and i just canceled my replacement phone.
Unroot and put the newest stock OTA on it. Take it to Sprint tell them it updated while you were away from your phone or sleeping and the battery was low when you realized your phone was dead you charged it up and powered it on only to discover your 4g no longer works.
to take a stab at your second question, were you drinking Red Poopers? Red wine, tequila and tabasco...
that's why I'm generally hung over

Unable to stream (Pandora, Songza, YouTube) over 3G, data works though...?

Data for browsing, etc works like normal... But I'm unable to stream any media on 3G, WiFi is fine and I don't have 4G. On YouTube I get an error about connection to the server being lost (something like that) - App or Browser - and Pandora/Songza just won't buffer, but the apps will load up fine.
Oh, also I on occasion will use WiFi tether to connect to the Wii to stream Netflix, but that works pretty well. Occasionally it needs to buffer.
Any guesses as to why, or more importantly how to fix this? I'm stock and rooted, LG8 firmware, but this was an issue prior to this.
Update prl and profile. Are you in a weak signal area?

So odd. I had updated both following my update to LG8 last week when I was at work... I just updated both again, and now all 3 are streaming just fine. I'm in a good signal area, and so is the are that I like to run in too. Weird. Guess it just needed another update. Thanks for the tip.

I was able to fix mine by changing my Sprint network from CDMA to LTE/CDMA.
WTF. So now tonight it's broken again. Even re-updated the PRL, etc... This is annoying as hell. And on an unrelated note, anytime I try and copy a URL in Chrome it crashes and doesn't copy. And copy/paste everywhere else just doesn't work. So mad.
very interesting...the issue hit LTE evo owners too. ....I have a conspiracy theory but unfortunately can not share it.
those that have contacted pandora get a letter that they are aware of the issue and working on a fix.
I have had the same happen to me, flashed lg8 and lg2 with no change. Still cannot stream.

So I'm not the only one having this problem. I thought I was going crazy.
i have been having issues with my evo3d and s3 for the last few weeks with pandora. i have tired all 12 of our demo phones and they are hit or miss, mostly misses lol.i have had a few customers asking why pandora isn't working too.
Still nothing after another PRL and Profile update. This is some bull.
Sprint is just slow and that's just how things are On 3g. There's nothing you can do to change Sprint 3g network it's old technology.

If that were the case then it wouldn't have worked on my Evo... When it did. So, I'm thinking that's not the case...
Anyway, I will place a call to tech support this afternoon, I just need access to a 2nd phone.
Welp. Call 1 was no help. All they had me do was type in some code on the dial pad that took the phone through the hands free activation process. Didn't work (duh)... And then I was told to clear the cache and cookies on my browser (how that'd help Pandora...?) which also didn't work. He then told me he could set me up with an appointment at a Sprint store. Uhm. No. Have to try another tech.
0 for 2. Again asked to update profile... Even after explaining I literally just did. Same with cookies/cache. When I reiterated that I can't stream via apps or a browser the tech sounded perplexed, and then we got disconnected.
So, is my best bet to unroot and take it in? Lame.
