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
Hey guys my 3g is not as fast anymore after constant flashing of roms and radios and now I never get over 500kbps..any suggestions?
I've been having the same problem! I seen somewhere about reconnecting your phone with Sprint towers, but can't find the post about it again anywhere.
Did yall try updating your profile?

Ive updated my radios, prl, profile..and I always do complete wipes and wipe multiple times before I install a rom..also I tried that data govenor removal mod and still nothing..i really dont want to unroot and bring to sprint to replace
Sorry but thats all i got. Ive noticed sometimes i get bad reception but i havnt up dated my radios since fresh 3.4 came out. Ive been running cm for a long time so that might be it but its not enough to make me flash back to sense to fix it. I hope you get everything figured out.

Hey no problem man I appreciated the help..I guess my next move will be to flash fresh Rom..the speed seems to come and go on myns rls 5 but on any other Rom speed is completely horrible but let's see..ill get back with results.
I've been having the same issues. I've noticed when running the speedtest app sometimes it detects the closest server being over in Europe (I'm from Wisconsin). It appears to be tower related. When I'm on the tower closest to my house it detects the closest location in Missouri? Awkward. I'm on CM 6.1.2 running snap 7.6 with turbo enabled. Most times I see speeds of .3 mbit. Turn on wifi and I instantly max out my connection at 8 mbit. If only 3g were that fast, lol.
I recently rooted my Evo and put CM7 nightly 12 on it. All was well, I even installed the Savaged Zen kernel. Even better. Just yesterday I updated to CM7 RC2 to give it a shot. Today I went to work and had to drive to a remote area where I don't get service, so I put my Evo in airplane mode to save battery life. (this was after having it overheat while charging, could be a hardware issue) At the end of the day I turned the 3G radio back on and nothing... It connects and disconnects to the tower. It will not send data and it will not place phone calls on the 3G connection (WiFi works). I did a restore back to nightly 12 to see if maybe it was a problem with the OS. Nothing. A few hours ago it began functioning again, but after checking it a few minutes ago I have discovered it is back to no connection. (the signal bars bounce between nothing and full, but never shows the X for no signal) Has anyone else had an issue like this? Should I restore back to sense and unroot to take advantage of my warranty? If this has already been posted before please direct me to the right thread.
I'm having the same problem. I installed Cyanogen RC 2 and had no problem since it came out. I went on vacation to a beach, and during my trip I switched it on to airplane mode since I was in a remote location. After turning it back on, I noticed I can't get the Data Connection to work. The 3g bar doesn't even show up, and after messing with the settings trying to fix the problem I managed to do nothing. I tried using a backup I made from a week past, and encountered the same problem. Then I flashed the newest nightly and still no Data whatsoever. Wifi works fine, and 4g is acting weird but I got it to work a few times. Does this have something to do with sprint?
I think it is the same as the 4G 3G hang. I typically get it while tethering and the phone is normaly quite warm.
So I managed to fix the problem. I ended up flashing Koni's Elite Rom
http://forum.xda-developers.com/showthread.php?t=941055
I got an error that said "Error 67 registration failure"
I updated my profile and it was automatically fixed. I'm not aware you can do this on cyanogen stock rom, but I think you can dial a number that will do this for you.
After getting the 3g to work again, I flashed back to the stock cyanogen, and it is still working. So for now im good to go.
I do think is sprint and not the rom because I did a restore to warm z and was still having the same problems. Also my brother's evo was doing the same thing and he doesnt have cm7 on it.
I figured it was something to do with the profile... I restored all the way back to sense and attempted to update profile, but it doesn't seem to be doing anything. I will try that ROM and see if it does anything. Why can't they just make this easy and allow updating of vital software that allows the radios to work on WiFi or from SDcard? This is dumb.
I tried that ROM and nothing works. Not really sure what to do. I might have to restore to Sense and unroot to take it back... I really want to avoid that if at all possible.
Unrooted my phone and getting a free replacement from Sprint. Still unsure of the problem, seems to work randomly.

I also have the same problem. No 3g data, gps, and 4g is acting weird.
I also had the same registration error number 67. My question is, how do you update your profile?
Hey everyone, I'm new here to the forum and have had my EVO for about 6 months now. First things first, I have searched quite a bit and havent really found problems specific to mine on here or google. Maybe I am just not searching for the right thing so bare with me please. A few months after I got it, I started realizing the 3g would take a long time to respond sometimes. For example, I would type in a web address and hit go and the 3g icon on the status bar would not do anything for sometimes up to 1 minute causing the browser to display (page not found). Other apps that require internet do this as well. One day I decided to do a factory reset and the problem went away. After a few weeks, it came back so i did another reset and fixed it. Now back to the same old problem. Finally got tired of doing resets so I'm trying to find out the real solution to the problem. I constantly clean the cache. Previously I did it manually, but now I use cache cleaner which seems to do a good job. I have also tried speed boost lite which doesnt do a bad job either but uninstalled since i like cache cleaner better. Profile and PRL updates help only for a short time even though it didnt really update after checking software versions. I've taken the phone to sprint, they've checked it out, said its fine, and that 10-30 seconds is normal and nothing to complain about. Maybe that would be the case if it was NORMAL but it is not. Has anyone heard of this or have any ideas to fix it? Sorry for all of the reading but if you have any advice at all, it is greatly appreciated. Thanks

Well there 3g service is down the drain right now and the lack of good ping could be the reason so my guess is 3g sucks it happens to my evo a lot so I use wifi and 4g when I can

Thanks for your reply. I'm am happy with the 3G most of the time. At my house, it is almost as fast my wifi (no i dont have slow internet at home either lol). I have no problem streaming HQ Pandora, youtube, and netflix in crystal clear quality on 3G. It is not the network, it is an issue with the phone, a setting, or an app that is causing the problem. If I was to factory reset the phone right now, the problem would go away. I just dont want to reset it anymore and have to reinstall everything. Time to try to figure out the real problem and stop taking the lazy way around
That is weird could be your phone you could back up your apps with titanium backup and restore away or try to unroot then reroot

i just reset, I did forget to mention in the OP that i am not rooted. Haven't gotten the balls to do it yet. I haven't found a good thread to read up on to root yet. Not that i've been looking that hard. I would like to root very soon though
Best way to root I think is unrevoked you need a computer but its easy as pie there are also guides on YouTube

ya i tried that before but every time i try something goes wrong and i cant do it. Even when i follow videos my phone just doesnt do the same thing as theirs for some reason. lol who knows
Just for ****s and giggles I gave it another go on rooting with unrevoked. Actually got it this time. I have no clue what happened last time. Went smoothly this time. So just basic root, nothing fancy. All i really wanted out of the root was wireless tether. Still want to figure out the unresponsive 3G issue though before it happens again
Glad to hear your on the dark side (rooted) you can learn a lot just by being rooted

Ya its nice so far but the reset did not fix the unresponsive 3G. Ugh its so annoying! Nobody has any ideas?!
Flash your first rom and do a nandroid

I am now running cm7 nightly build 83 off of rom manager. I love it!
I'm not having the 3g issue now. Internet seems much faster on this rom
Hello,
I've searched around the Epic 4G Touch forums as best I could, but sadly I couldn't find anything that was exactly this problem (although I found some interesting articles about wifi sleep time but they don't seem to apply). I'm experiencing an annoying issue where I can connect Wifi just fine, but if the phone is left for a small period of time (~10 minutes), wifi appears as if it's still connected, however it cannot send/receive data. When this happens, the wifi status says it's "connected", but there is no data connection. The only way to to get the data back is to turn off wifi, wait for 3/4G connection to initialize, then turn Wifi back on to refresh it...then it's fine again until I set the phone down again.
I had this problem on stock EL29, so I rooted and flashed Phantom Blazer ROM (very cool ROM, but I'm still experiencing the same issue). After reading the threads on here about wifi sleep times (apparently they're backwards with ICS roms), I've experimented with every setting, yet I still have the same issue--Wifi is fine as long as I'm using the phone, I set it down, after about 10 minutes pick it back up, says it's still connected, but no data connection.
has anybody experienced this problem with this phone? I'm about to unroot my phone/go back to factory so I can take it in to a Sprint store, the problem is they (trying not to be offensive) don't seem to know very much about this device. I thought I'd ask the pros before I return it, get an iPhone, and have to eat my words about how cool Android is vs. iPhone in front of all my friends. I'm hoping there's a reliable ROM or app that can resolve this vs. having to just replace the device!
Thanks for your help!
I'm not the only one
I'm not the only one with this problem:
edit: I can't post links to androidforums.com or anywhere else, but this same problem is all over the interwebs and nobody has a solution.
I'm sure it's not my router as my ASUS tablet/laptops/girlfriend's iPhone experiences no connectivity problems. I'm thinking this is a hardware problem with some of these devices. I will unroot/reset to factory tonight and let you know what happens.
What channel is your router on? And what type is it A/B/G/N?
This is s known TW ICS bug, most likely kernel related. Almost everyone is having this issue and there is no fix until Samsung decides to repair it. There are quite a few posts similar to this one. If you're using XDA's search function, it's not very good. Try using Google next time and search XDA that way.

Hey guys, thanks for the response. Just before I unrooted/reset to factory I tried one last solution--download an app called "Wifi Fixer". It has resolved a lot of these problems. It's not 100%, but after testing it for a day so far, I've only had to manually refresh the connection once or twice. It's a lot better, even liveable, and I won't be resetting to factory afterall, at least not until Samsung provides an update. So if anyone is having the same problem, try Wifi Fixer, hopefully it gives you a similar level of success...I'm not super happy about having to run another background process all the time, but it doesn't seem to affect battery, and the fix it provides is worth it to me.
Cheers!
Huh - a couple of things. Noticed this problem crept back in FF18 and didn't know why until I went back and checked the wpa_supplicant.conf that I'm using. The line ap_scan=2 was missing; after adding it back in the signal strength is back to full and stable.
I'll bump the thread but it appears the config changes here still hold after all:
http://forum.xda-developers.com/showthread.php?t=1569348
This should also avoid having the WiFi fixer there as you can specify the country in wpa_supplicant.conf manually.
Thanks for looking in to this! A couple questions from a noob like me though:
When you say the problem crept back in FF18 ... what does that mean? Is that something that exists in the "stock" version of the Epic 4G touch from Sprint?
The manual config file tweaks you're describing ... is that something I can perform myself?
Basically I'm wondering if it's "safe" to revert to stock in order to get consistent wifi signal, or if it's something I'm experiencing because of the ROM I'm using.
Thanks!
