Can anyone help with a 3g problem - Epic 4G Q&A, Help & Troubleshooting

For some reason any internet browser I try with 3g wont work at all. I have also noticed that 3g isnt working with any application. The symbol appears but nothing works. I have tried reflshing and updating the profile and PRL but no luck. Can anyone help me out please.

I'm also having a near nonexistant 3g ever since PRL update.

my PRL won't update
but I noticed Sprint was acting strangely last night
and it was effecting Sprint/Nextel/Boost as a whole
I think something is still up, because my texts are lagging
and when I make phone calls it takes like 10-15 seconds for me to hear it ring
and I know it's not just my phone. my cousin's Boost was the doing the same
as well as my friend Yesenia's Sprint

Sounds like a radio issue. Do you keep getting roaming warnings?

[Q] phone will not let me do anything while roaming. any ideas?

so i was running the VR_GengerSense_Revolution_B4 rom about 4 days ago with now problem doing ANYTHING on my phone while in digital roaming. then i left the roaming areas and went into sprint service area and came back into the roaming area and now my phone wont do anything while roaming. i cant make or receive calls or messages or use any apps or the net. i have 2-4 bars of signal but if i try to do anything it tells me i have no network connection. yesterday i switched to the BeKinged-STOCK-Beta-V1-Clark44 rom thinking that changing everything would fix it but it didn't i went back into that same roaming area today and its the same story. does anybody have any idea of what i could do to fix this? I'm at a loss i tried every setting and was on the phone with sprint for about an hr. and nothing. Ive tried different radios and still nothing. i was thinking of un-rooting and seeing if that changed it. it baffles my that it just randomly started with out me changing anything on my phone.
thanks for any input.
i updated the PRL tonight hopefully that will help \. gonna try that before i un-root.
PRL update didn't help. unrooted taking it to sprint tomorrow.

[Q] Issue with EVO on Boost

I was having issues with my 3G cutting out randomly. I would be in a known coverage area, and in the middle of a speed test, wifi tether, or any other app requiring internet, the 3G would just stop working. The 3G icon would blink as if it was trying to reconnect, but wouldn't. I would either have to restart the device or cycle the mobile internet on and off. I would also get error code 67 and 104 randomly as well. Today, I updated my Radio to 2.15.00.05.02, but haven't really had the chance to see if it's functioning correctly. Any advice? I'm a bit of a noob, so keep it simple for me.
Sitting at home with the EVO on 3G and just got error 104 again. Running...
ANDROID 2.2
PRI 1.90_003
PRL 60672
Just updated to ANDROID 2.3 and the latest RADIO combo pack and I'm still having the issue. During SpeedTest, the 3G stops responding randomly. Sometimes it picks back up again, but most of the time, it will stop responding altogether. Settings issue? Any help would be great.
A Tower is down on Sprint (sub-Boost Mobile).
That is what's causing your in and out fades.
Should be updated by end of the week.
Boost Mobile (EVO)
Android 2.2
2.15.00.11.19 (downgraded as I thought it was radio, but will be upgradeing back to Radio 2.15.00.05.02 after Tower is repaired)
Software 3.70.651.1
PRL 61007
same problem here, but with good towers
hey guys I have the samsung epic with the same proble, it works fine and fast on 3g but sometimes it just stop working. the 3g arow keeps sending, and I get the same error codes, so, what can I do to fix this? ah my epic is on boost mobile
So others are having this issue as well. Interesting....anyone got any ideas?

I have the same problem. It has nothing to do with the towers. I am running synergy RC2 and my 3g will drop. I have to then disable the 3g and reinable it for the 3g to work. This will last for 3 minutes to 5 hours. It's very annoying. I have come to the conclusion that it is either software related or the PRL.
Some PRL's have more problems than others. It seems that the boost PRL (I think it is 61007) will be running a speed test and cut out and I get an error saying there has been a network communication error. 60678 seems to work best for me although I have to keep resetting the 3g.
I have the same issue with the Speedtest.net app. It cuts out with a network error. Anyone else got any input???

[Q] HELP!!!!! 3G no good!

my phone has been rooted for 1 year now and so far have had no problems what so ever, but just recently i flashed synergy rom and all hell broke loose. my phones 4g works fine and so does wifi but my 3G would not start, it would turn on for about 1 second then go straight to 1x.
things i have tried......
update my profile and prl...nothing
##data##, menu, restore....nothing
pulled the battery like about 155752 times....nothing
nandroid restore to a time where it was working...thing
flashed like 6 different roms and still nothing works.
flashed new radios and still a no go..
i tried to do the whole metro pcs flash but then changed my mind not to go to metro as its network is crapy. i went to qpst and cdma and reverted everything back to how it was, so i dont see why it would mess up my 3G
i have no idea what else to do, any help will be greatly appreciated.
If it is 1x, that shows the true data strength. You may have excellent connection, but poor data in that area, or the server is just temporarily overloaded. It'll correct itself. Previously, sense roms would always show 3G even if it was a 1x connection, but most developers put in that fix to show the true strength, like in aosp.
Thanks for the reply. the thing is that my wife has an evo as well and shes right next to me and gets perfect 3g data connections, and i was getting error 67 upon trying to update prl and profile. as soon as i did the reset on the ##data## it went away, and now it wont even connect to 1x at all...man its so frustrating, ive searched and search but nothing.
same thing has happened to me, tried chatting 3 times, and called tech support once, so far no data.
try this...i did not work for me at all but it might work for you...good luck buddy you'll need it lol...this crap is frustrating as hell.

ive had similar problems... just flashed a rom,, 3g working but hotspot isnt.... i need help too
Sense ROM's show 3G to identify a data connection, while the bars are actually displaying the voice connection. I believe aosp ROM's strickly display the data speed since voice reception is generally good. This may just be a placebo affect and you think you have poor 3G. I would suggest running a speed test on both ROM's (your current one and the one you found "good" data speeds on) to ensure that it's not the ROM itself.

I've got the same exact issue, but I've been on Synergy for a while now. As of last night though, no 3g... My France's unrooted EVO works just fine, and I've been in a few different areas, so I know it's not the tower. I've done the same things the OP has done and still nothing... Is it possible for the Rom to fry out the 3g??
Sent from my PC36100 using XDA App
Ok ive got mines working. However its still a little sketchy but atleast 3g doesnt go away. After going tjrough the steps in my last post, I did ##786# and resetted everything. Then reflashed my rom and walah!
This worked for me.
Step 1: Open dial pad , ##3282# enter
Step 2: Select "Edit Mode", then input your MSL number
Step 3: Select "Data Profile", then press menu button
Step 4: Select "Restore", then press ok. Should reboot on it's own. If not reboot.
You said you did something similar but figured it wouldn't hurt.
I did that, but didnt work for me. However every phone is different and every little bit helps.

ICS Leak - Missed Calls and Data Drops on LTE

I have been running the ICS leak for quite some time now and haven't had any major problems with it until now. Ever since they launched LTE in my area I have been having trouble with my phone not receiving calls. When I finally talk to the person that was trying to call me, they say that it would ring twice and then go to voicemail. My phone never rings and I don't receive any notifications about missed calls. I have also noticed that when it does this, my data no longer works at all. If I toggle airplane mode, it will snap the phone out of it.
This problem seems to be growing in frequency. ATT tried to sell me some BS about the phone gets clogged with interference from travelling through low signal areas and they re-registered my phone on the network and told me to give it a try. My phone is still having this issue. LG had no clue what was going on with my phone.
Does anyone have any idea of what could be going on and what I can do to fix this?
New rom? Just in case something did happen with the rom somehow.

I'm also having the same problem on official Bell ICS...

Why not use the official release?

Voice data is not sent over the LTE network but instead is sent over EDGE, HSUPA or HSDPA (gsm) networks. This is because LTE was designed to handle data only. Currently a few mobile operators are begging to launch voice over LTE capabilities (VoLTE). However ATT does not support VoLTE capabilities so whenever you place or receive a call your handset will switch to the gsm network to handle voice.After the call has ended your handset usually takes a few seconds to automatically switch back to LTE if available. During the time your phone is switching back networks your data will be inaccessible. If your phone does not switch back or your data never returns then you can toggle on/off airplane mode to reset it as you have mentioned doing. This should not be happening very often, unlike what you describe. What I would suggest is flashing HoNo's CWM official V20c ICS from att. This will update your phones baseband and firmware for your radios and I've also heard is more stable and has improved battery life. Hope I could help.

I had the same problems with the leak at home where I have a weak signal. Never had any problems with CM9 or GB. When I switched to the official rom all those problems went away. So I think it was just a baseband issue with the leak.

We ( my wife and I) got the same issue... With Bell.
So we sent both phone ( GB by the way non root ) to bell to get them repair ...
Sent back the phone... 1 h later ... got the same issue .. so they ( futuretel in Markham Ont Canada) dont find the issue, they just reflash the phone.
sent it and ... weeks later got it back ... lost it again ... but they change hardware and also reflash.
Now it's my turn ...
I'm still waiting for my phone because when i got it back, got issue ( probably firmware ) because I lost the speaker and speakerphone ... so if someone call me i was not able to ear them...
Sent back the phone again for repair and now i'm waiting.
Update my wife phone 2 day's ago with ICS from LG( bell ) and I dont think she got the issue.
If it's happening again, LG will have to step in because it's 2 repair for the same issue.
Since we are not alone in this situation we will be able to remove the hypothesis
of interference in our house!
And again ... when I was talking with someone from Bell support, I told them I would like to try custom Rom if the issue is still there...
The person agree with me... yes weard from someone from bell...
Other than that ... it would be good for people to "catlog" the drop signal / no voice service...
Some one have a good tool that can track that specific issue ?
Thanks!

Network loss

Ok guys, having a real problem here. Often when I am connected to either 3g or wifi my phone will stop picking up signal suddenly. AIt's almost every time and I will have to disconnect from the network manually and reconnect and it will instantly pick up signal again for a while then it'll repeat. When it suddenly stops it doesn't show on the status bar that I have lost any signal. With 3g its kinda just at a stand still not receiving or uploading and with wifi it just stays the same but I'm still not picking up a signal because by web pages won't load neither will other apps that require network load until I manully disconnect and reconnect. Is anyone else having a problem like this? I don't think it was like this when I firs got my phone a month ago. I'm at a loss. Any help is much appreciated. Oh I'm completely stock btw haven't rooted........(yet) lol

It has happened to me a couple times that I have noticed. I will be streaming music and walking and all of a sudden, nothing.
Even a soft reboot does not help. It will require a full reboot generally to solve the issue. I have not been able to identify the issue specifically. I suspect it might be related to LTE testing in my area.
What's the LTE status in your area?
No lte yet but as I stated earlier it happens on wifi too. It'll still show that the signal is connected but my pages want load at all after it happens and when I try to refresh it'll say that the webpage could not load because there is no network. Only until I manually shut off 3g or wifi in the settings and turn it back on will it pick up signal again but only for about 5 minutes. This has happened in various locations on 3g and wifi and will even happen at home wifi.

This has happened to me as well... A lot . Stock.. on various roms.. No lte as well.. But it's in the works

I've had this problem too. Sprint replaced my phone and it never happened again.
I think reactivating hands free actually fixed my problem...for now anyway. It's not losing network like it was before. All I did was enter on the phone dial pad ##72786# that'll reactivate. Hope this helps
