4G problems - EVO 4G General

Hey guys I live in a 4g area and had it for about 2-3 weeks now, been getting great connecting till I tried it the other night. Now all I get is connecting to Sprint and then disconnecting. This loops over and over. I've checked my MAC and everything is the way it should. I've never changed anything either like flash a new Rom or a new wimax. Anyone have any idea. Think its my phone? The 4g tower since its not officially here yet. Any help would be appreciated thanks.

If you are not in a 4g service area, then you cannot get reliable service.

If you are rooted, you might want to try what is listed below. It was suggested by another member on the WIMAX thread in the development Section. THis is to check your RSA Keys. My RSA keys are broken and I have the same issue as you. 4g connection is detected/available but cannot connect and the connection resets over and over again. MAC Address is correct and all that good stuff with the most current Radio & WIMAX version. I am also in a 4g area that is not official, but my buddy can connect w/o a hitch.
Use Terminal Emulator:
"Also go into terminal. Make sure your are superuser, remount /system as RW, then type in "grep RSA /dev/mtd/mtd0", you should get RSA PRIVATE KEY BEGIN, and RSA PRIVATE KEY END at the bottom of the listing. If not your Wimax keys are hosed."

Freshevo ROM 4g won't connect?

I'm running the latest Freshevo ROM. Going thru a 4G area and it keeps notifying me that their is a 4G network available...it says connecting to sprint and then goes back to "Searching"
Any ideas?

I've posted this same question over in the Q&A forum. But I'm on Fresh 3.1.0.2 with Netarchy's Fresh Kernel. My 4g just gets stuck at scanning. Someone suggested checking to see if your MAC address (menu-settings-about phone-hardware info) matches the MAC address under your battery.
Mine does and I still dont get anything. If yours doesnt.... search for MAC address fix.
Someone also suggested deleting a trees.xml, but I dont know what that does so I havent done it yet.
I have been able to connect in the past week without problem on fresh 3.2.
Today I tried to connect and I get the same thing you are seeing, it tries to authenticate, then drops back to scanning.
I know the 4g in my area is not "live" yet but has been stable for a few weeks.
I checked with another evo user here and they cannot connect either.
I don't think its a ROM or a phone problem. See if anyone else in your area can get 4g before you start mucking with your phone.
I wish I could ask others but I'm on a train...we are passing thru a 4G area. We stopped at a station for 10 minutes where I rebooted and turned on 4G and still just "searching"
Gonna check MAC now...
4g cannot jump from tower to tower. If you are on a train, you are likely jumping to different towers before you can connect.
From what I have read, 4g is only good for about 2 miles.
Makes sense, we weren't moving at one point and it was disconnecting. Then we got to our next station and it connected. Got it and then we started moving again. So looks like the wimax radios do work for me...hmmm.

4g connects but no data transfer

Edit: the problem is with my 4g, not pdanet. On my phone itself with 4g on I can't load any webpages or get any other data connection. Worked last Friday, and haven't made any changes to the phone. Running burnt 1.3 with net 421 smartass nohavs.
Try reinstalling the pdaNet on both the phone and computer.
If still nothing, try turning your phone off then back on.
Sometimes people never turn their phones off.
Hope this helps.
i am one of those people who never turn off their phones >.>
anyway I had to reinstall it on the pc today anyway. It decided to not work anymore v.v havent reinstalled on my phone yet though.
Bump for edit

I have the same problem. I don't use pdanet. I can connect to the 4G network but I cant load a webpage or download anything. Basically no data transfer. I took it to a Sprint store and they are just going to replace the phone.
Transfer that's the word i was looking for
I'm going to reflash the wimax radio when I get home and my phone isn't dying, i'd hate to have to replace the phone.

Bah, reflashing the radio didn't help. Anyone got any ideas?

I am having the same problem with mine. It was working up until a few weeks ago, but now I can connect but it is painfully slow to load web pages. The page loads like 3/4's of the way, and then hangs for the rest of the page. The last 1/4 of loading takes a few minutes. That isn't even on a graphic-heavy page.
I am able to tether on my laptop though.
I am on OMJ's ROM, and have the most up-to-date radios that I know of

I've had this problem before too and the only way I found to fix it was to un-root and flash the stock rom. Then check if it works.
If it does work, root and flash a rom, I used sprint lovers rom and I didn't have any 4G issues with loading pages.....
Same here....recent issue....not sure what's up. Could be the network and not the phone maybe....what area are you trying to connect to 4g?
sent from my brain through my fingers through multiple electronic devices to your brain
Buddy I work with has an evo too and connected just fine standing next to me.
I can't imagine it fried the radio itself since it connects fine.
Sent from my PC36100 using XDA App
well that blows....
i dont' have another evo to test it with....so I was HOPING it was a network thing....but I'm thinking it's not.
I checked my RSA keys.....they're still good.....
I have a NANDROID backup from a while ago when my 4g was still working...I'll flash it the next time I get to a 4g area and see if that fixes the problem.
I haven't touched my phone in terms of mods in over 2 months...so I'm wondering what the hell happened. I hate when **** like this just comes out of nowhere.
Please let me know via this thead if you have any new news.
new WiMax update is out in the dev forums. I'm going to flash now and see if it fixes my problems when i'm at work later (sidenote: my town has 4G, i just cant get it to connect at my house damn....trees)
Well I'm at a different place than normal but after flashing the new radio 4g is working.

I found out that my issue here was the app adfree.... if I stopped using that app, webpages on 4g load fine.
.....did nothing and 4g is working now....
aside from poking around in the adb shell to see if my RSA keys and MAC were still in tact (which they are)...my 4g started working again all by itself.
it was down for a week....and by "down" I mean that I could connect absolutely fine....get an IP....but could not transfer ANY data up or down. I did reboot serveral times while it was not working and that didn't fix the issue either.
Whatever....as long as it's working again...
Hmm i've been using adfree too but it didn't cause any problems. I agree Dell, as long as it's working.

4G stuck at obtaining IP address

Alright I tried searching for this but keep finding only WIFI issues. First of all my wife has the Epic as well, she connects to 4G just fine, as for me I did as well but after I flashed midNIGHTS 2.4 rom I cannot get my 4G to connect, instead it hangs at obtaining ip address then disconnects and tries again. If anyone has any solutions that would be great.

Have you tried using a static ip?
Well not sure how to go about doing that. My WIFI connects just fine its the 4G thats not connecting.
My 4G is also not connecting... i know for sure 4g is available in my are because my friends evo can connect to 4g. i downgraded from dk28 to DI18, still no lick on 4g working. any ideas?
If you're having the same problem I had then your 4G radio is shot. It is known but very limited problem on the epic and their is no fix for it. Go to the sprint store and they'll replace it.
Damn well I hope thats not true, that means I'll have to Odin back to stock 2.1 which honestly I hate doing. It's always a hold your breathe thing to make sure it flashes correctly for me. Anyways this really sucks though, but the fact that its trying to obtain an ip makes you believe that its shot?
Try to turn 4G from the settings menu and tell me if it says unknown.

No I click Turn On, it goes to connecting then hangs at obtaining IP address...30 seconds or so Disconnected. And then flashes scanning for a split second and show Disconnected
Okay your 4g radio is working, but its weird that it won't connect. Flash it back to stock and see what happens. If it still doesn't work, your local sprint awaits.

Thats what I don't want to have to do But if that fixes it then I must.
I just hate the process of going back to stock then root then ext4 then rom then test it out again. BOOO this is gonna be a long night/day
Alright before I start the long process, would reflashing the modem for dk28 help at all?
Oh I read it as a wifi issue..sorry..yeah I had the same thing where wimax wouldn't connect..had to flash back to DI18 to get it working :/
Well I Odin'd back to stock DI18 and still same issue bit since I'm back to stock 2.1 I guess ill head to sprint store.

4g stuck
I know this is an old thread but i have this issue from time to time. I go to school where I have no connection at all, voice or data, and when i get back home where i have solid 4g coverage it wont connect and just hangs on "obtaining IP address". I know nothing is defective because it has done this in the past and it eventually starts working the next day. Anyone find out anything new?

[Q] Epic Won't Connect to 4G

Here's teh scoop...
I was in Vegas at CES and all was fine. I was tethering and 4G was blazing. Left on Friday, got back to SoCal and on Monday my Epic running Bonzai4All (RFS) would no longer connect to the 4G network. Found out from Sprint there was a trouble ticket in my area and 4G was down for a couple days. It's back up now but my phone won't connect anymore. Took it to a corp repair store (after having flashed back to stock of course) but they couldn't fix it so they ordered me a "new" one.
I don't think it's a hardware issue because when I click the 4G icon the phone cycles through SCANNING>CONNECTING>OBTAINING IP ADDRESS and then it just disconnects. Feels more like a programming issue (ie, dialer codes... then some numeric setting somewhere in the programming menu)
Has anyone else had this happen to them. I did nothing to my phone between the time I was in Vegas and back in SoCal so other than the outage, the phone no longer connecting to 4G seems quite random.
4G is noG
I have the epic4g, I live in Vegas.
Although this is supposed to be 4G for the entire city, the phone spends 95% of the time "disconnected" from 4G.
I have already had sprint replace the phone, the same thing happens with the new phone.
It seems its a software issue, if I turn on 4G and move, do anything, it will disconnect. Heck, it even disconnected in the parking lot outside the Sprint store. Of course they kept telling me there was nothing wrong with the phone when they test, so I go outside, try to connect to sprint.com, get error of no connection and bring phone back in.
On a recent trip, I attempted to use 4G to rent a movie for my son. In the course of 30 minutes, it must have disconnected once every 1-2 minutes. It does not reconnect on its own, you have to manually disconnect, then reconnect to get it running again. It appears if you are "mobile", it has major issues. If you are sitting in one place (not walking or anything) it will keep its connection.
Kind of retarded if you ask me - I know 100% its a phone issue, something is messed up. Of course, when I complain to Sprint, I am the only one having this issue.
I am actually going to try to get them to credit me the 10 bucks a month back, after all, I never use 4G - not because I dont want to, its just not worth the hassle. I cannot even browse the web - it disconnects so often I get the no connection error screen. 3G has no issues, but is slow.
I have searched many forums, but cannot find any fixes for this issue. It would appear that you are having the same deal as I am now.
No idea. My phones locked on 4g 80% of the time. While driving, walking etc. Only use 3g in buildings made of kryptonite that block signals.

I live right outside of Baltimore, and according to sprints coverage maps I should have 4g where i live. We all know how coverage maps go, but i am getting the "obtaining ip address" then fail. But I just kind of ignored it and thought nothing of it.
After seeing other people with similar problems, do you think i should have it serviced? i am paying for insurance.
Did anybody figure this out?
This happened to me after flashing a new rom, seemed to work after a reboot.
i have the same problem, and a simple reboot did NOT my problem.
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 | EC05 Modem.
Note: 4G was working before i tested UrbanDecay, which was a EG22 ROM. I did flash SRF1.2 with the EG22 installed. i have tried updating the modem and I'm back to EC05. still no luck.
Suggestions?
This happened to me. Some type of data corruption. I had to Odin back to a prerooted tar, not restore anything, test 4G, working then only restored apps with no data. When I did restore data I lost 4G again. So do not restore any data. Set everything back up again.

Yeah I tried everything first, even had Sprint refresh my phone. I guess some WiMax files got corrupted. You could try a reflash but if your ROM backs up and restores data it probably will still not work. I was able to restore apps only and selectively restore a few apps with Titanium though.

Shift only uses 1x data, claims 3G

I generally use my shift at home or work on wifi. This week I'm on vacation and have been using Sprint's network primarily. I was using a CM7 nightly for a while and noticed that I've never seen the 3g icon, only 1x. I confirmed this by installing an app from the market called 'Opensignal' which shows details about your connection, which tower you're connected to, etc.
I flashed to a sense based ROM (Mik) and have the same issue- 1x only. However, it now always displays the 3g logo when data is 1x, even if roaming.
It seems that something in my phone is keeping me stuck without 3g that persists through reinstalls/wipes. I'm hoping there is some type of hidden setting or config option I can look at outside of the standard settings in the system.
Any ideas other than flashing back to stock/unrooted?
You will find that the stock sense rom will show 3G always as well. You can open up the dialer and dial ##33284# Choose EVDO engineering, and look at the state.
And if not in a sense rom *#*#info#*#* will let you view you connection details.
Toasted by Nightly.
Unfortunately I would ruu back to stock, update profile and prl in update section then see if that helps. Run speed tests and keep a record of results to help in the process of elimination. Could it just be the tower you're near or some Podunk town out in the sticks that doesn't have good equipment? Go to a sprint store with working displays. Do speed tests with the display then your phone. Maybe you got a lemon?
You could be roaming or on an old system. Turn roaming off and set network to sprint only and see if that makes any difference. I know years ago I went to my home town in the Midwest and throughput and signal was poor until I went into a major city (like the capital) then speed and signal was good again.
Thanks, I didn't realize HTC always made the 3g logo show- that's really stupid. *#*#info#*#* shows me good stuff and re-confirms me getting 1x only.
Will any of the settings listed attempt 3G data only? I set it to EVDO but it seemed to stay at 1x.

##3282# & ##33284# are your best bet to edit anything if you're not planning on running an RUU, really you shouldn't have to, just turn EvDo only on and see if it even connects. Maybe the 1X towers are stronger than EvDo, if you have it at all.
Reset data profile entirely through ##3282# - you need your MSL - MSL Reader is on the market.
Try that and document your speed results, etc. Then update your prl. If you really want to, then go ahead and apply the 3G speed fix mentioned in Android Development (not necessary but if you're concerned with speed you might wanna try every step.)
If all that fails, you do still have the RUU and start fresh approach. Personally before I'd do anything I'd get ahold of another android device, maybe not HTC, and see what it's doing for speed, etc.

Great info. Using the info code I've set it to EVDO only but it still says its at 1xRTT, even after a reboot(!). My wife has a Sprint LG optimus S- I've looked at its settings and its connected @ 3G so I know whatever tower in my area should connect.
I got my MSL from that app and can get to edit mode via ##3282# but I do not see an option to reset, only to change to other profiles that appear to have the same config. It was choosing profile 1, I changed it to 0 with the same results.
How do I reset data profile?
Edit: ##33284# lists evdo as 0 (disabled) but does update info as to its signal strength and so on. This is all still with the phone set to EVDO only but yet connecting at 1xRTT.
I seem to have it working now. The change I made was ##3282#, EVDO, preferred mode = auto. This was previously set to CDMA. After a reboot I now have 3g.
I'm curious what this is set to for others? I've never been in these screens before and have this feeling that I've never had 3g data (I've had my phone since launch day).
Ive reflashed CM7 and 3g works there too now, i'm seeing the 3g icon for the first time.
Also its quite sneaky that HTC/Sprint only show the 3g icon on a Sense ROM. Had i never installed a non-sense based ROM i'd have never really known that i was stuck on 1x. Shame on HTC/Sprint.

I would like to say this thread has helped me achieve EVDO (ive been 1x also since release). Sadly this doesn't work on AOSP roms for me, but i'm happy just getting what i'm paying for... and have been but haven't received. Its noticeably faster.
BUT.. for noobs not used to the ##3282# menu, after making a change, press the menu button and commit the change. I had gone through these steps changing the drop down and immediately restarting. Apparently you have to manually save these settings.. or at least on my phone.
where are you guys entering these numbers and "EVDO"? because mine is also showing 1x and i wanna fix that

you get free thanks i guess... mouse slip up
anyway, its in your dialer, just use the keys as if the 'code' is a phone number
LOL double thanks
By the way i found out if you enable EVDO(DDTM) you might not receive some calls, just putting preferred mode on automatic will do the trick

1 Reboot your HTC EVO Shift 4G.
2 Press your phone icon on the screen.
3 Enter ##3282#.
4 You have to give it roughly 10 seconds for the EPST screen to appear.
5 If the 1st 3 steps don't work, you may have to restore to the Stock ROM.

Seem to have worked for me as well except on the next day...I got an (I believe unrelated) random wake-up reboot, it just decided to keep connecting in1x mode. Now I'm back to mik and I'm constantly in evdo rev a mode
I really like cm and I've had it fully setup to my liking...then when I discovered about opensignal and the whole 1x thing...I feel like I'm missing out on something. I think its more ocd than anything else since cm7 is fully functional anyway...but still. I do hope they figure out what the prob is. I can't wait to go back to cm
i dont need a signature
