I'm having trouble with my EVO staying in 3G coverage. My phone is fully rooted and running Froyo (The problems were the same with the Eclair build however), have the 2.05+ radio installed (however the problems were the same with the 1.39 radio as well) and I'm living in Michigan.
At any given time my phone will slip into 1X coverage and will seem to lock in there. When I first received the phone I felt like the phone quality was subpar compared to the Hero I had prior. I'm not sure if its been a firmware issue or network issue or simply a phone issue (starting to think the later), but hoping its a simple fix with something else.
About a week ago I was on a trip across Michigan which should have had 3g coverage the entire way (I was a passenger and trying to use wireless tethering to do some work along the trip). I would constantly go into 1X and would have to restart my phone to get back in 3G. Even at home I'll go into 1X and will have to reboot my phone to get it back to 3G.
I've tried Real Signal as well during these times and it also shows no 3G signal.
Anyways, anyone else experience this? Is it likely a bad radio or something else. I hate to have to return the phone and go through that process plus root again but I might have to at this point.
Thanks for any help that can be provided!!
Hmmm, whereabouts in MI? I am all over the south east and have never seen my phone drop out of 3G yet.
Have you tried wiping everything and trying stock rom w/OTA 1.47 just to make sure it isn't the ROM?
I am having the exact same problem. Using 2.0xxx radio and Fresh 0.5.3. I recently exchanged my phone and got a new one. The first phone did not do this
Try this:
When it shows you no 3G coverage, instead of restarting, go to-- SETTINGS> WIRELESS & NETWORKS> scroll down and look at "Mobile Network". When i get the 3g problem it says "Connection Failed". I think uncheck that box and re-check it and it connects back to 3g again (for a time, but then I have to do it again).
My MOBILE NETWORK settings are: Data Roaming = OFF, Always-on mobile data = ON, and CDM Roaming mode is set to: SPRINT only. Call guard = ON but i dunno what that means.
I dunno wtf is going on with this. Im in Houston and this issue is really pissing me off because i actually got a Novatek screen this time and don't want to risk taking the phone back and getting the Epson...
Anyone else experiencing this retarded issue?
Elegant: I'm in SE Michigan as well. I've tried several roms and have had issues with them all. I'm currently using a Froyo rom with similar issues as I've had with stock and other eclair roms.
As for checking/unchecking the box as you stated in Froyo I don't have that option available... I'm sure there's another way to get to it but I can't through settings. I think there was a #* code to get to where you are talking about but I'd have to look again.
It is a very annoying issue and like yourself I don't want to have to return my phone if there's a simple fix.
On a side note: How do I find out what panel I have? I've been considering the kernel that would get rid of the 30 fps cap but haven't yet pulled the trigger in part because I don't know which panel I have - and because I need to learn a little more about it before I go ahead with it.

Post 3 tells how to determine screen
Thanks for your help - got the kernel and now get around 40 FPS. Now if I can just figure out why the phone goes in and out of 3g on occasion. Its really not as big a deal when I'm at home but when I travel it is a pain.
well i returned my phone and got one with an Epson screen. im using Fresh 1.0.1 and it is even worse. i cant even use 3g data for more than 5 seconds before it disconnects. i've read some stuff about APN but dont know how to refresh/update them. i've updated PRL and Profile and nothing helps. how am i having this problem with 2 phones running 2 different ROMs? last rom was fresh 0.5.3 and now it is fresh 1.0.1...
anyone help with this APN issue? (i dont even know what APN stands for)
i actually am using the kernel for 55 FPS for Epson screens. would that be a factor either?
I'm and having the same issue with 3g.
Every thing worked fine with the first stock root of 1.32.651.1, PRI 1.40_003, PRL 60666.
With the second root of 1.47.651.1, PRI 1.34.651.1 now my 3g is unstable.
I don't know what FPS has to do with any of this, but I put radio radio-1.39.00.04.26 and it seems to improve a tiny bit, but I don't know how to update back to PRI 1.40_003.
Not happy
Also having problems in SE Michigan. Just started today after installation of Fresh 1.0.1 and the new radios. I also have a co-worker with and unrooted EVO and the latest OTA/Radio with the same problem.
I have a rooted EVO (DC 3.2.3). My wife has a stock EVO (fully updated).
Last night our phones started bouncing between roaming/sprint 3G, while we were sitting at home.
We started getting this error if we turned off Data Roam:
"Data Call Failure
Error Code 67: Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again."
The error pops every time it tries to connect to Sprint's mobile network and fails.
We also live in Michigan. Perhaps they are doing provisioning?
Rebooting + update Profile/PRL seems to help, sometimes, but not permanently.
I am having the same issue with my 3g coverage.
When I go into my settings and turn mobile network on, it connects but then immediately says connection failed.
Does anyone have any suggestions as this is getting really annoying and frustrating.
Went to a Sprint store last night; apparently Michigan was having some significant network issues (the store reps said their phones kept getting disconnected as well), and that it was expected to be resolved by sometime today. After a reboot last night, I haven't had any more issues myself.
Has anyone else experienced any issues with 4G not connecting after changes in data connection strength?
I'm usually riding the subway to and from work so am not really using 4G and then have WiFi as soon as I get into the office.
Took a cab this morning and had 4G during the ride but had a spot where it dropped out. The connection never picked up again unless I manually turned 4G off and back on.
Running Starburst 1.9.8
Anyone else have this issue?
well i just go the phone a few days ago and haven't rooted yet but i did manually flash the ek02 update. my phone will drop 4g and scan but after maybe 1 or 2 attempts it will not try to scan again. just noticing it so i will keep an eye on whats going on. looked at the info in ##data# and ti looks like its set to rescan every 120 seconds so not sure whats going on.
Can't do speedtest (Network Communication Issues--TRY AGAIN)
Can't browse the internet (Unable to connect)
Can't play internet games ( Dragonplay poker,etc...)
Ok, this happens every now and then even when I have 4g with all my bars mainly when I get to work and starts back working maybe 1hr or 2hrs later (when I'm home I mostly use wifi but my mobile/gps works). I try to test it by trying to see my speed on the speedtest app but does nothing. Even tried the "faster fix" method and it doesn't work. Tried the S3 method with tightening the screws but they were already tight. Cleared AGPS and updated AGPS, loads up 20 something in use and finds GPS but still not working.
My area doesn't have LTE yet but the surrounding areas (mainly 2 hrs away has it). Call Tmo but hell they don't know if there doing any work in my area or not. Just kind of strange..I been here at work for 3 hrs now and haven't start up yet but still showing 4g with 2 bars now. Yesterday it took about 1hr maybe, then boom starts working (playing games, browsing, speedtest). Just trying to see has anyone else came across this issue and fixed it. I also read other users returning the phone to get another and only to find out it happens on it the new one too. Not sure if its a hardware issue or software cause verzion, att, and sprint also has this issue
Phone is rooted and have Alpha 5 with baseband MDL. APN seems to be like every other TMO US LTE (fast.t-mobile.com and other settings). Network Mode: LTE/GSM/WCDMA (auto connect) selected..GPS on Mobile on...
Installed the update this morning, and now I've totally lost data connection twice today. Shows 4 bars of LTE, but won't connect. Switching airplane mode on/off fixes it instantly.
This hasn't happened before (had it about 6 weeks), so I'm guessing this is a new bug.
I'd bet heavier on T-mobile doing work on towers in your area. They're doing this quite often these days. And I was seeing this behavior long before the update. May be no way to know for sure.
This has happened 4 or 5 times since I got my phone on Wednesday. I am on Verizon Wireless, if that matters.
I first noticed this issue when I left work. When I got out of range from WiFi, my phone never transitioned to cellular data. This was in an area where I have very strong signal (-82dBm). After about 2 minutes, I toggled airplane mode on and off, and about a minute later, I finally got my 4G working. This has happened at least twice.
Last night, I sent multiple SMS messages to friends. This morning, when I woke up, I checked my phone and there were no responses. I left my apartment, which means I went out of WiFi range, and suddenly I received 4 SMS messages from the previous night (time-stamped as yesterday).
Has anyone else experienced any of these issues? I've never had this problem with any Verizon phone I've owned.
So this just happened again after breakfast. I didn't have WiFi on, but when I got to the car and went to play Spotify, I had no signal. I went into the cellular network settings and changed "preferred network type" from "global" to "LTE / CDMA".
Once I did that, my connection came back. It could have just been a coincidence. I'll see if it happens anymore today.
I'm having the exact problem. Unfortunately no solution that I've found except toggling what you already tried or restarting the phone

Do you still have this issue when you have the preferred network type set to LTE / CDMA?
I don't mind leaving it set to that if that solves the problem.
I'm glad I know other people are having this problem and it isn't a hardware issue (unless all of us are having the same hardware issue).
It sticks for a while then happens again unfortunately. I did end up doing a factory reset yesterday morning and it hasn't occurred since... But I'm not confident it will stick
