Hi
I have Black 3.01 which work well except for one annoying problem.
When in an area of no signal it constantly turns on. As soon as I turn it off, on it comes again.
It's not activesync (I've done fake server trick)or any other software I've installed. I've not got it set to auto attach to GPRS/G3. I've looked in the notification queue and running programmes. I can't see anything that is causing it. If I turn the radio off, it stays off.
Any idea's
This is driving me nuts.
Could it be the radio version?
This was happening to me for a while and I think I traced it back to a weather program constantly trying to do updates. But it was never clear, so I did a hard reset, reinstalled everything and the problem went away.
Yes, I considered that. However I've got everything disabled that might try to connect. And it only happens when there is no signal.
But I might have to do as you did and hard reset and re-install one programme at a time.
Unless someone else has a clue?
This has happened to me several times on black 3.0. Not sure what is doing it - I have no programs installed that would be attempting to wake up the device or to connect to a data network....
Hey people!
I tried searching the forums for this issue but couldn't find anything, so if this is already discussed please forgive me and redirect me.
Anyway, when I am using wifi the 3g connection disappears (which I've set it to) but sometimes, especially after a long while, when I turn the wifi off the 3G connection won't reappear. I tried turning 3G off and on again without success. The only thing that helps is a soft reset of the phone, which is really annoying.
Has anyone else had a similar problem like this?
I did see the other thread about the 3G connection stopping and hanging, but since they at least still had the 3G connection icon in the top bar I consider this to be a totally different issue.
Anyone knows what might cause this?
Thanks!
If you carefully search, this has been discussed many times.
Basically, HTC Desire is not that good on waking up the 3G connection after turned off.
When you use WiFi, the 3G will not be turned off, but it will not be used.
Yes, it happens to me several times ... usually I just "wait" ... 1 or 2 minutes.
Other user said by turning ON then OFF flight mode will help.
Yeah ... this issue is bad
Cheers man. Waiting won't help me since I've waited up to an hour just to see what happens. But I'll try the flight mode trick
Got a strange issue here. My wife and I have had evos since release and 4g worked fine on both when we got them. We're in Boston and since Boston didn't have official 4g until last week, neither of us have used the 4g radio until we read that boston was flipped on last week. On both evos, we're finding that when we toggle 4g on, it takes the normal ~20 seconds to turn on and then it scans for a second or 2 before turning itself off. After turning off, it turns on again and repeats this on/off routine indefinitely. I am only able to stop the loop by pressing the "4g off" button while the radio is scanning for a few seconds. The radio then turns off and stays off. On my wife's phone, the scanning only happens for a split second so it's almost impossible to stop the loop. Her battery dies in ~4-5 hours because of this.
Both evos are stock 2.2 and both pretty different launcher/app setups. I've tried removing common apps between the phones with no luck. I'm at a loss for what might be causing this. I've searched and found this thread but there is no solution:

Next step is to call sprint but that is always a last resort. Any ideas?
that's pretty weird. From what i know this happens when you root and flash roms/kernels. Your mac address gets changed. I'm having the same issue atm, but my evo is rooted.
Either your mac address was changed for some reason, or your rsa keys are gone.

i read about people losing 4g due to rooting issues and keys getting lost. but from what i read, it seems these people are able to turn on their 4g radio without issue but it just scans forever even though they are located within range of a 4g tower. i'm seeing something different here. the 4g radio goes into an on/off loop and barely scans at all.
Not sure I'll be much of a help, but....
Make sure you are outside in a guaranteed coverage area. 4G signal doesn't have the penetration or range of 3G/EV or 1x Voice radios. Confirm that you have 4G signal in that area with someone else who has a 4G capable device.
Then, if that doesn't help, you can go for more extreme methods, such has completely reset one of them back to factory, redo your data profile and test again.
If that doesn't work, you'll probably be stuck with calling Sprint.
If it were me, I'd do the outside and confirm 4G first, then call sprint and see if they can refresh your profile or something before going to the extreme of hard resetting back to factory.
Just because the maps say you have 4G, doesn't mean you do right where you are. There's an app in the market that folks are using to find actual coverage, called Mapviewer by Sensorly. That may help you see where others have reported good signal.
GL!!!!!
thanks for the tips. when i was playing around with 4g back when i first got the evo, i found that i could turn the 4g radio on even when there was no 4g signal and it would just scan for a long time. is this still how it is supposed to work or did they implement some auto-off feature such that the radio turns itself off if it doesn't see a signals after a second or 2? because right now, the 2 evos in my house turn off immediately after turning on and then continue the on/off loop. so it doesn't seem like i can get the evos to behave properly even without 4g signal. i may try calling sprint to try the data reset.
I would give it some time to ramp up - I started in another thread how all of a sudden I'm getting 4G in NJ - and we're not supposed to have it yet at all. I can connect, but it just cycles through connected and diconnected (making it essentially unusable). I would imagine it will begin to normalize after a while.
edit - misread the op, sounds like you're having a different kind of issue. nm
Also, that is how the antenna works - it will keep scanning indefinately until either the battery is dead, or it connects.

nah he's having the same exact issue as me.
Here is the order of what happens:
1. Turning on...
2. Scanning...
3. Authenticating with sprint.. (sometimes you see this, sometimes you dont)
4. Turning off
5. Go back to 1, and repeat
^^ From what he said, that is pretty much exactly what it sounds like. And that's the same problem I'm having with rooted phone.

that's pretty much it except i've never gotten to the authenticating part since this issue started. also, my phone scans for a few seconds before the 4g turns off. my wife's phone turns off almost instantly after the radio finishes turning on. this is the biggest issue because there is no way to interrupt the loop on her phone. even a reboot with battery pull doesn't stop it.
performed a hard reset on my wife's evo and that fixed it on her phone. mine will be tricker because of customizations. what a PITA.
called sprint and the tech support basically said the 2.2 update has caused lots of problems and they are waiting for "htc and android" to release fixes. so, of course, not sprint's fault at all. she told me just to use 3g and not 4g. pathetic.
did the hard reset on my evo and now the 4g radio won't turn on at all. it just sits on "turning on 4g..." for a few minutes before coming back with "unable to start 4g". i've tried 3 different types of hard resets (buttons, clear storage, and ##786#) and all with the same result. sprint is telling me my phone may be hosed but they won't give me a replacement because a fix is supposed to be released eventually. ugh...
Did anyone find a solution to this problem?
I was in Las Vegas on Friday, and 4G worked fine, but since then my 4G is doing what the OP said. I haven't changed anything in the Rom or Kernel.
Thanks!
Hi all, sorry if this has been asked before but some of these threads are thousands of posts deep... I'm using the latest Myn Warm rom, with the stock kernel that's bundled with it (#17 I believe). When I try to turn on 4G, it turns on, scans, tries to connect to Sprint, then turns off and repeats that cycle over and over. It never actually establishes a connection. If I do a hot restart, then it kicks in. Similarly, turning off 4G requires a reboot as well (which I know is a known issue). Anyone else having this issue and is there a fix out there?
Thanks as always

Not sure I've seen anyone have the issue with trying to turn 4g on, but give this a shot if you haven't already, it was buried in that massive thread:
1. Menu-->Settings-->Wireless & Networks
2. Turn 4G OFF--> then ON--> and OFF again, waiting for radio to completely turn off and on each time.
3. Reboot and check your logs (download logger HERE)
Flashed CM 7.2 on a friend's Evo 4G and as far as I know it was working just fine, but it has started randomly vibrating every 5 minutes or so, even when it's turned off. Any suggestions as to what might be causing it?
Yes, I am very sure I thoroughly wiped it before installing. And there don't to be any persistent notifications.
