[Q] Call Disconnected - Any Advice?

I've been seeing this problem for a few weeks now, with several different ROMs, including the original rooted stock ROM now. In nearly all of my recent calls, I get disconnected one or more times with the message "Call disconnected" and a "Dismiss" button. I'm thinking that this is because of my EVO and not the other side, since usually if they accidentally hang up or something the call just ends without a message box. As far as I can tell, I have good reception (at least according to the bars), and this is happening at home, where I've not had the problem before.
Does anyone know what could be causing this? My wife's EVO is not rooted, and she does not seem to be having this problem. But then again, I've not had the problem until fairly recently either. I've tried updating my profile and PRL with each new ROM, but it doesn't seem to have made a difference. Anyone have any suggestions as to how to stop this from happening?

Go into the settings menu andbupdate both your PRL and your profile. That *should* help with reception related issues.

Unfortunately, I've tried both of those things. I just did some testing today, and it seems that my phone is unable to stay connected during a phone call for more than five minutes before disconnecting, even if I don't touch the phone and just leave it sitting on a table.
Any other ideas? As far as I know, I haven't ever flashed my radio away from its default (2.15.00.11.19), and I'm currently using the leaked stock gingerbread ROM (build number 4.12.651.1 CL41771 release-keys and kernel 2.6.35.10-gaa602b7 [email protected] #1).
Maybe it's time to unroot and contact Sprint?

You can try downgrading from 2.15.00.11.19 to 2.15.00.09.01. You can download it from http://www.mediafire.com/file/jyedjkp1bm5amwm/EVO_Radio_2.15.00.09.01.zip
Afterwards, go into recovery, wipe cache & dalvik cache then flash the zip. You will be taken to the radio update screen and appear to hang. don't worry or get impatient. After it is finished, you will reboot into recovery and see the words "clearing cache" at the top of the screen. Simply select reboot and then you will boot to your homescreen. The initial boot will take a tad longer since it will be rebuilding the dalvik.

Hmm... I'm hesitant to downgrade my radio because my wife has an EVO with the same radio version number and hers doesn't have this problem. Granted, she is not rooted...

I understand. I've downgraded and upgraded everything several times for testing purposes and troubleshooting purposes and have never had a problem. The only hing about flashing radios is patience and not to pull the battery. Anyway, you can always call Sprint and see if they can troubleshoot it for you from their end.

I would contact sprint @ 877-809-6696 (advanced tech supp). Ask them to push a full reprovision to your device. See if that helps any. I was having issues when when on the airave, I was unable to receive incoming calls. This corrected it. I did try all the other steps listed above without any success.

This is interesting. I unrooted to test things out before calling Sprint, and the problem went away. I was able to stay connected for an hour (where before I couldn't last longer than 10-15 minutes). Yay, fixed, right? So, I rooted again and didn't install any ROMs or anything, just rooted, and the problem came back.
So, I have a solution, but I don't like it very much because it means I need to stay unrooted. Anyone have any idea why simply rooting the phone with Unrevoked 3 (and doing nothing else) could cause calls to disconnect? I'd love to be able to root again, but I can't deal with a phone that randomly disconnects all the time.

I am interested in this as well as I am rooted using unrevoked and get disconnected as well. I do find that it mainly happens though talking to people who have service on AT&T.. Quite wierd. All I hear is a beep then disconnected. This happens when I first place a call and it rings once or twice then beep, disconnected...

This may not be related to rooting. I'm still communicating with Sprint about this issue, and along they way they replaced my phone entirely, and the problem is still happening. Very frustrating, but it makes it very clear that the problem actually has nothing to do with the hardware. I'm pretty sure there is some network configuration problem on their end now. I'm waiting to root my new phone until this issue has been resolved. It is killing me!

So whats the final call on this ..?
Is it Rooting , Is it network .. i am too getting psyche with this .

I'm pretty sure it is not rooting. But I don't yet know for certain what it is. Sprint thought there might be something wrong with the antenna on my phone, but they had already replaced the phone, so I think that is unlikely. They gave me a femtocell range extender to use in my house. Basically, I plug it into my broadband connection, and it is like having a mini cell tower in my house, giving me a very strong connection. Sure enough, when connected to that, I haven't had any calls drop. However, my phone still sometimes doesn't connect to the femtocell and instead connects to some other tower for some reason. My wife's phone doesn't do this, so I still think there is something wrong with my phone. I may contact Sprint again about this. ...sigh...

What is your area some area evo don't work properly like on rahim yar khan in this time connection don't work properly some signal drop and some time up i sure after few day signal work properly then problems will be solve.

My phone EVO is doing this now as well. Has anyone heard/read a solution?

I am having the same issue, out of the blue. No problems up until a few days ago. I'm wondering if it is maybe an issue with a certain version of the Evo. I have a version 002. Thoughts?

Greg_99 any progress on what might be causing this issue?

error code 128 data call failure

This has been happening to me for the last couple of days. Out of the blue my phone will pop this error: Data call failure. Error code 128. Unable to establish wireless data connection. I have done some research on this error message and most of the things I found had to do with using the phone as a hot spot. I am not using that feature. I am using a custom rom that I have had on for a couple of months now. Nothing has changed on my phone. I have tried updating the prl and then updating the profile. I have pulled the battery and left it off for half an hour. None of the other phones on my account have this issue. It is particular to my phone only. Is it this something I can call sprint about and they can reset or do I need to flash my radio again or take it in to sprint?

Had the same thing happen to me today. Called sprint and they said there was a data issue going on in my area. I say its rubbish but whatever.

That's been happening to me all day today. I thought it was maybe the kernel I installed today (more freedom) but after seeing this maybe it was the earthquake on the east coast causing problems with the network?

I have been getting these errors all day today as well.

i've been getting it all day... I thought it was kernel

I keep getting that error to. Thought i messed up my phone. Guess it was the earth quake, That **** was crazy though, never felt one before. Anyway after it happened i lost service on my phone for like 2 hours, kept getting beeping noises when i would try to make a call.

Sorry to hear others having this problem as well but I am glad that it probably isn't my phone. I would hate to get my evo replaced with a newer one that can't be rooted.

I know running CM7 right now and getting no 3g speeds right. Lame. But I got wifi though.

It can be rooted! These Dev's don't let us down, come-on man.

This started happening to me after the earthquake. In NYC

you mean Virgina? But yes, the last few days especially today after the quake. Ivebeen getting it alot.
I just had to reinstall synergy because it started freakingout saying that my andriod process had stop working, and a media process stopped working. was driving me insane.

Yeah know issue with Sprint call tech and do ctms ticket and maybe prl update or maybe * 18. The issue may be cleared by now .

Just the last couple days? I been getting these errors on and off for months now... before I rooted, and bricked my phone, so I'd say it has something to do with sprint not having enough bandwidth... or something like that anyway....

data call failure error 128
My Evo 4G started getting this Data Call Failure Error 128 last week (Wed), also only when I unlock... It is only a message, but everything works fine afterwards. It would happen about 5 times a day.
Then I went to Mexico for the weekend (3 days) and was roaming over there. Not once did the message pop up. Everything was fine, roaming data, text messages, phone calls. Thought everything was fixed. Came back on Monday and once I was on the Sprint network, started receiving the messages again on unlock.
I updated PRL and Profile and everything. That didn't stop it. Tried changing from Sprint to automatic roaming and that didn't really do anything. I thought it was a couple of apps i had (like Green Power that turns off data and turns it back on) but uninstalled it and the messages kept popping up. Tried enabling always-on data and that seems to work but that drains the battery faster than usual. Been searching all android forums looking for others in this situation and it seems like only a Sprint/HTC issue (Evo 4G, 3D and Shift). This is getting very annoying. It happens about 5 times a day.
My wife thinks that it's Sprint fixing and adjusting their network getting ready for the iPhone rush.

Wow, glad to know that I'm not the only one. I think that I had somehow did something wrong with my phone. I keep on getting these Data Call Failure - Error Code 128 messages several times a day. I tried reflashing a new rom, then doing it again. Must not be the rom, but Sprint. Annoying!!!!

it was just a sprint issues

Also cannot call the *2 or the *4 automated lines to sprint, get a busy signal and pop up saying "network is busy try again later", but can get through to sprint on a landline just fine. Apparently I cannot connect to what the sprint tech says is the "automated lines". I continue to get the error code 128 repeatedly, whether on wifi, 3g or 4g, and Sprints only "remedy" is to do a factory re-set which I have read has not affect.

Wi-fi broken after root.

Hey guys. I just rooted my E4GT and didn't install the kies application first. My phone is rooted and everything seems to be functioning except for the wi-fi. Whenever I go to turn on the wi-fi, it turns on, scans for a network and then the wi-fi turns off again. Am I boned? PLEASE HELP!

epic 4g wifi broke
Same for me, after Rooting with oden the wifi searches and then turns off, any help?

I'm sorry you're having the same issue. I haven't found any solutions yet. Would you please keep me in the loop if you find one? Isn't there an IRC channel where some of these guys go and help answer questions?

Something went wrong with your flash. No worries tho you just got to go back to stock and root again. Are you familiar with Titanium Backup? If you are back up all your user apps + data. Then ODIN back to factory restore. Then auto-root with this method. Lastly restore all your apps with titanium

this happened to me but i fixed it easily
forget your wifi
connect again with password and repeat it again until it works maybe 3 times

This is good advice. Do what Kogama recommends and you should be up and running. If not, hit the "HowTo's" link in my signature and follow the steps for a Hands Free Reset. Fast. Simple. Effective. Probably a good idea to do one anyway when you make major changes such as rooting or ROM hopping.

after i rebooted the wifi stopped working and i cant get it work again actually..where is this hands free reset i cant find it only the activation which I also did again

Just_s and Kogama - That method did not work for me. By time I had typed in the WPA key, the wi-fi antennae had already shut itself off.
BUT
KelvCast - your method totally worked. Is it me or does this antennae get piss poor signal strength? But I thank you VERY much for helping me. I'm all good to go. Now on to trying to figure out my write permissions on my Kindle Fire =/

for kelvcast's way you have to completely change your modem back too right? ....damn
im running a completely different rom btw...

"Hands free"is the same as "activation". Sorry that didn't work for you. The only time I had an issue with WiFi, "forgetting" the connection and then logging in fresh was what worked for me. Any other data/ connection issues I've had have been resolved via the hands free reset.
As far as your other question, you don't need to change modems, but it won't hurt if you do.

I have the same problem as OP. Rooted using the Zerg exploit, running stock ROM. When you turn the Wifi on, it only gives you like 5-10s before it turns itself back off, also the MAC address field shows unavailable.
Assuming it's an issue with the root process. The odd thing is mine worked fine for over a week, and just randomly died today while trying to connect to wifi at school. Was going to reflash stock kernel with ODIN, and see if it effects it at all.

How do you forget your wifi?

Hated to do it, but had to flash stock ROM, just the kernel didn't do it.

I was having the same problems... flashing rogue kernel 1.3 fixed it perfectly for me. Hope it helps

My WiFi is working fine with the method I used. Rooted phone and everything.
Not sure if I will be keeping Sprint anyway.
Did a speed test on my moms old LG Verizon phone running at 600mhz. Compared it to my Sprint SGSII running at 1.2ghz dual core. On the LG, I get a little more that 1/2 a meg per second (which is decent in this area) as compared to .01 - .1 meg per second on my SGSII. So there is a BIG difference in speed. I know its not the phone, but the network. Going to do my due diligence and keep the sprint phone for at least another day. But if it goes as it is now, I will be going to a Verizon store Sunday and switching carriers again. Sprint doesnt seem to be better that TMO. Sunday is my 3rd day so if I return everything to sprint, I get a full refund.

Yeah it's hit or miss. In my neighborhood, my buddies with Verizon pull down 1/3-1/2 more bandwidth, but my phone works in any basement in the area and theirs doesn't, go figure. In the mid-town/downtown areas both carriers perform about the same around here (Omaha, NE).
Now if you're talking WiMax and LTE thats a different story altogether.
As for the Thread topic: I think I know what broke mine- I restored a bunch of apps using Appextractor, and think restoring the "Settings.apk" in the system section toasted it. I tried flashing a few different kernels to no avail (Did not try the rogue kernel, however).

Lost WiFi after rooting Epic 4G Touch
I have been fighting this problem for a week now, finally I installed clockwork mod following a youtube video titled (How to Install Clockworkmod on the Samsung Epic 4G Touch - Latest) sorry cant post link new user arent allowed to post links. my phone was already rooted. I now have my WiFi Back.
Hope This Helps

I have tried every method I have been able to find.....Still no wifi. I rooted via this guide (http://forum.xda-developers.com/showthread.php?t=1265429). After following that guide my wifi did not work. Just scans and then turns off. Does not even see any networks. I flashed the stock kernal. Still no wifi. I don't know what else to do. I am going to try a factory restore. If that doesn't work I might need to send my phone in.....This blows.

Factory data reset brought it back

[Q] A bunch of questions in one???

All right I have a few question I figured I'd ask in one thread they pertain to one another I guess.
1. (blazer rom 4.0) So last night I flashed this rom because i have not given GB a chance everything went well flashed fine......but when I booted the phone everything came up but I had no service. not a empty signal display it had the circle with the slash through it no service. under about phone it said I had no number, no prl, no nothing. after doing a shutdown and restart service would come on periodically and the it would go back to what I had just mentioned.
2. (prl and profile update) so the whole reason I flashed I flashed back was to update my prl and profile. but for some reason I can not do either. for this one i just flashed back stock el29. It would say and show that I had a 3g signal but everytime I the instant I would hit update the signal would vanish and 5 seconds later i would get (error: no connection) thried this with 3g,4g,wifi no luck.
this also happen when I was talking to a sprint rep setting my epic up, it took an hour and half to get my phone updated, no bueno.
do we have prl zips for are phone? and where, if so?
and any help with the blazer rom would be great. From the little bit I messed with it, it was a very smooth and snappy rom.

There are no prl zips that IM AWARE of. I'm pretty sure there are none! Idk try to see if sprint repair can find something wrong with it! Or you can try to flash a different modem. Sorry about your issues

That happened to my previous phone too. I had to reboot my phone 6-7 times to get connected. And sometime, I didn't receive call unless I keep the phone awake. T-Mobile sent me a replacement, but I had to pay $20 for shipping and exchange fee. My new phone has no problem so far. There are a few complain on T-Mobile Support site about the same kind of issue.
