[Q] CyanogenMod 7 - no 3g - Epic 4G Q&A, Help & Troubleshooting

has anyone else experienced this problem? right now im on MarcusantRom Revival v3 and 3g works fine but whenever i flash to CM7 (or MIUI) the 3g wont work at all, i get the 3g icon but no connection unless i connect to wifi. ive tried reflashing, using apn backup and restore,updating my profile(on EI22 Stockish or Marcusant) then reflashing CM7, and messing around in the *#*#4636#*#* menu but so far nothing has worked. Also im on boost mobile but i don't understand why my 3g works on almost all roms but wont work with CM7.

On boost I think you need to back up your apn while on touchwiz and restore it on cmy. Not positive though

[Q] I need help with CM 6.1 RC1

i installed this about a week or two ago on my phone and everything worked perfectly,i loved it. but now for some reason,my wifi does NOT work. It scans,finds,and connects,but does nothing after that. no web pages load,the market doesnt load,NADA. Anyone got any ideas? Any and all help will be greatly appreciated
Reboot if you havent already, and remove that access point and re-add it. If that doesnt help, reflash ROM

tried all the above,backed up to 6.0 and wifi worked,did a complete re flash of the rom and still nothing =(
btw-i dont know too much about flashing,re-flashing,so everything i do is through Rom Manager,dont know if that makes a difference
I have had issues with cm now and then. When i reflash, i do a wipe. If that doesnt work, i let the phone update when its in bootloader which sets up the enginering version of espresso. I then reflash from there and good as new. If that still doesnt work, redownload rom and flash. Occasionally the file may corrupt on the sd card. That has happened to me.

Try turning on bluetooth first then wifi. I read it in one of the CM threads and it works for me. I had the same problem.

I think this is still the trick for any CM based ROM
Well it is only a release candidate. I had major issues on RC1. I am running build 171 of the nightlies, everything is stable more or less. Wifi will occasionally glitch out, but that's partly my router I think. In any case, rebooting the phone or the router normally fixes it.

[Q] 3g not working

I'm running cm7 nightly v28. For some reason the 3g does no work. The only way I can access data is to pick up some 4g. Is this a common problem? Fix?
Reflash the rom. I haven't had the issue but that could work.

Reflash the rom, and if its not in your power widget, check mobile data under wifi settings.
Sometimes mine do go right away so I turn it off and on quickly and that seems to do the trick.
Sent from my PC36100 using XDA App
Thanks for the responses. I tried reflashing but that didn't work. The turned mobile data on and off but got nothing. I even tried going in airplane mode and then out and nada. I think I might try flashing a different rom to get it working. Could it also be my PRL?
Its shouldn't affect it, but being on the latest PRL never hurts.
Make sure that its on in wireless networks...
This is my EVO, there are many like it, but this one is mine....
Mobile network is stuck on turning on -__-
Well try to reboot it real quick. And sometimes it can take it a minute or two to actually turn on.
I've rebooted several times. I've done full wipes and even to different roms. It just won't budge. :-/
I was having issues with 3G connectivity earlier. Getting lots of code 67's and data call notices. 4G was working fine so I switched on and used that. 3G is fine and back to normal now.

Did anyone come up with a concrete answer on this issue? I too have this problem and tried all the suggestions except 4g... it's not available in my area. Any help would be much appreciated, thanks.
Try flashing a sense rom and updating your profile and prl

4G losing connection and not reconnecting

Is anyone else having this? I still have 3g connected, but if I look at the phone periodically, the 4g has an X on it (red x, im on honeyglow) it will reconnect if I toggle it, but if it drops it will not reconnect, like from 3g or wifi.
Is this s known issue and is there a fix?
Oh, and Im on the LosTKernal OC to 1.6 (stable) and Starburst 1.6, it did it on 1.7 as well.
Thanks
Which kernels have you previously tried? I tried one that made my 4g stop connecting even after switching back to stock but I did find a fix so give me some details on what you've tried so far....
Sent from my SPH-D710 using xda premium
I think I have only used ZedoMax, and then this LosT Kernel, or versions of it.
I had midnight ROM, now have been running Starburst. I think another configuration I had dropped signal on data a lot and had trouble switching between WIFI 3g and 4g. But this has helped my LOS issues as best I can tell.
If I can get 4g to work (im in Dallas, lots of 4g) great, if not Ill just try to ignore it.
If you have a fix, that would be great.
Thanks!
Honestly, if I had a choice between this and the screen wake lag, I'd not worry about 4g.
The screen wake lag is rediculous, it takes 3 full seconds to wake up with my class 10 8g card in it.
Well, what I did was Odined Crawrj's odexed with root and Busybox. You would want the deodexed version obviously. Run that in PDA slot. It will keep your data but then you will have to Odin back akernel with CWM like LoSt. It fixed all of the 4g and Wifi not connecting crap I had going on from something I triedthat had borked changes

Pageplus ics data issue

I got my evo 4g 2 days ago.I use pageplus for my provider. I had to flash the evo to get it to work. Everything went great. On any gingerbread rom everything works. I have tried every ics rom and everything works great except i only get 1x data.I'm not sure if it is an apn issue, but i dont know how to change the apn in ics. Any help would be greatly appreciated.
update
I know now its not the APN. I didn't realize that had to do with mms and that part works great. Weird thing is i can flash back to any gb rom and i get 3g again. I understand it might not be true 3g but you can tell a huge difference from the 1x i am getting on any ics rom. Does anyone have any ideas what i can do to get the 3g working on the ics roms?
have you tried rebooting 1 or 2 times after the ics flashes? usually that clears up a lot of problems people have when flashing the ics roms. i personally have never had this issue and have always been on sprint so i can't really help you but figured id throw this at you
edit: also what ics rom have you flashed because im running the team D.I.R.T. cm9 port and its simply flawless so far
Thanks for the advice. I have rebooted many times, no luck. I tried every ics rom i found in here. Everyone drops my data to 1x. As soon as i flash a gb rom i get 3g back. Is there a setting i need to find or a way to force it back to 3g?
in miui i think there is a setting to force 3g but i think thats the only rom that does it. gb or ics. so im not really sure about straight ics. sorry

[Q] No 3g after installing an AOKP/CM9 theme

I was checking out some of the themes that i had downloaded to see which one i liked the most and after a few installs i noticed that my phone was no longer getting 3g/hspa+ ? I had done nothing except install and reboot like instructed in the discription. I was installing them via "Themes" settings. Im currently on AOKP build 39 with the latest nightly from Franco (R191), I have never seen this before which is why i thought id post this thread. I have tried the following and got no fix:
tried *#*#4636#*#* and selected radio band/automatic but got nothing.
tried a refresh on the APN and got nothing
tried Mobile networks/Network operators/both "Select Automatically" and choosing T-mobile and no 3g still =(. Im stuck on EDGE:2
The radio that i have been on for a while now is xxkk6 which has worked pretty good for me coming from Phoenix,AZ
Dont know what else to do, someone help please
Why make two threads for the same problem?

Before creating a "theme broke 3g" thread. Did you happen to call your carrier and see if there has been an outage reported in your area? Have you tried to reflash rom, gapps and kernel and does the problem persist?
good day.

It was not done intentionally
Sent from my Nexus S using xda premium
I'm having the same problem. Was working fine on HSPA last night and woke up to Edge only all day. It's not a network outage and it's not my account as my SIM works on HSPA on my backup HTC Amaze. I was recently on CM9 Nightly 6/20 but I'll try going back to the stock rom and see what that does.
Edit: Tried reverting to complete stock everything and I'm still stuck on Edge only. I'll try a friend's SIM out and make sure it's not my account/IMEI issue, otherwise something has to be wrong with the phone, but I don't know what

There is no outage in my area because everyone that i know has T-mobile and there phone works fine. Re flash rom, gapps, kernel and problem still remains
Either me bringing it back to stock/oem lock then unlock or my phone fixed itself. At first when i was done bringing it back to stock, it was still saying i was on edge, then after about an hour when i tried to root my phone i noticed that 3g/h back up. I still dont know what exactly the root cause but whatever its fixed
