[SOLVED]Can't get 4g or 3g. Only E.

I fixed it by flashing a new ROM and wiping all the data!

Someone please help! I don't know what to do!

Nevermind, I think I fixed it!

I fixed it by changing the band to GSM Preferred/GSM ALL but now I only get E. Any way I can get back 4g?

Change it back to automatic or Odin kl1 modem from rootzwiki team kang post.

I changed it to auto, and i'm getting signal. Time to check if 4g. Thanks.
EDIT: It shows signal, but Im not getting any. Can't send text or browse web. Time to odin modem.

I flashed it, and I went to settings and looked at the network mode: It was GSM only. I changed it to auto mode. It seems to still get and send texts, and I looked at band selection with the dialer code, and there wasn't a star besides anything. I think it might've worked, but I still only get e.

By flashed I mean odined. Lol

I tried changing it to automatic in the band selection menu, and it showed signal, but texts didn't send.

Also, if it means anything, I can't change it to wcdma only in settings.

I had same issue and this is how I fixed it.
disable data connection and switch your phone off, remove the back cover and remove sim card completely. Then re-insert sim card and turn your phone back on and it should ask you to re-enable data connection once it boots up.
let me know if this helps

I did this, but it didn't ask me to turn it back on, so I turned it on manually, and still only E.

Other phones receive 3G? Perhaps T-Mobile is servicing your area? This has happened to me but I had no control over it.

Did you by any chance flash a rom port?

Weird. My issue was that I was testing a few of the skyrocket modems. After using Odin to get kl1 it worked again. Yeah i would sugeest resetting apn in wireless settings .
Sent from my SGH-T989 using XDA App

Here's what I did that messed with my 3G
I flashed skyrocket roms.
So what I did was wipe everything. Go to mounts and storage and format system. Then flash Juggernaut or any other rom you desire. Then you're done

WiFi turns off by itself

Got my sgs3 Sunday and when I got home turned on WiFi and started playing with it I notice that I lose network for a second after about 15 mins and my WiFi icon on the status bar disappear but network comes back on .. but in settings it is greyed out and I can't turn it off then back on till I reboot 0_o...thought maybe after I rooted and flash AOKP it would be fixed but no! I'm on T-Mobile and AOKP..so is it a bad WiFi driver or...? Any ideas?

#*0011# press the menu key. Select wifi. uncheck wifi power saver mode. Its should be green when on black off. Make sure its not on and done go back to home screen. Your phone should reboot the wifi driver and your done.
This method works for 4.0.4 any of the roms. Cm10 doesn't work. Cm9 haven't tried but I'm sure it'll work for u.
Hit the thanks if I've helped!

JB has these wifi issues I was expiriencing the same problems on cm10 as well. (I know not the same but both are jb) I decided to downgrade to the intrigue rom r3. It has smooth transitions. Real buttery and it let me access the wifi power saver mode by down ng the method above. I'll look into aokp and see if I can find a fix for u.

its called avoid bad connections on cm10

For anyone who has already turned off WiFi PSM, is anyone experiencing this setting turning itself back on? I have turned it off twice today and every so often it turns back on which ends up turning my WiFi back off...

Question: are you rebooting your phone when this happens?
Cuz if you are that's normal on every reboot you have to go back and turn it off again.

I was not rebooting the phone. I am currently trying a different rom to see if that solves anything.

Weird

Well it still keeps happening. I switched from intrigue rom to freegs3. I'm currently using the phone at work and it happened right before my eyes while using Tapatalk... I had to turn off power saver mode yet again
Sent from my SGH-T999 using Tapatalk 2

would the method above work for me? since yesterday, my wifi kept turning on by itself. After I turned the wifi off for like a couple minutes then it'll turn on automatically again. I have the Keep Wifi on during sleep set as "only when plugged in" and it never happen to be before until yesterday. My power saving in the setting menu has always been off too. Please help! :crying::crying:

Install the app called "Wifi Fixer" app to the solve the issue.

Whatever Google did to cause a variety of wakelock problems, having a strong wifi signal seems to solve them. Apparently, wakelocks occur when there are unreliable connections to Google's servers.

CM10 bugs....how to downgrade to ICS

I installed the cm10 rom about 2 weeks ago. I love jelly bean and cm10 dont get me wrong but i have been noticing that i can not send picture messages when connected to 3g or wifi (i have to reboot the phone everytime i want to send a picture) also my 3g would randomly disappear (it disconnects without showing that its disconnected). I have to put the phone on airplane mode and then reconnect to 3g. Just a few days ago my s3 stopped letting me use the wifi at my job (it said trying to avoid poor signal or something like that). The wifi signal at my job is very strong and i went into the wifi settings and disable the "avoid poor signal" feature. Still it wouldnt connect but it connects to the wifi at my house. I just want to know if im the only person experiencing this. Also how would i be able to switch back to ics from jb? Is it a quick process? Can it be done str8 from my phone without using my computer? Can i do it using mobile odin? If odin is needed?

Going back to ics is as simple as wiping the normal things, then flashing a ics based rom.

So, now that you're back on ICS, you should give CM10 another try. That build was like 2 months old. Those bugs you were talking about have been squashed. Pretty stable at this point.

[Q] Issues - UGH

I'm having some issues. I am on Incredible HD RLS 2, I haven't been able to get on WiFi and this isn't the only ROM where WiFi isn't working. It will just never connect. Well, I tried to install ICS Official global CM9 upon initial boot it said it couldn't read my SIM. I powered down pulled the SIM put it back in and put the phone back together and then I couldn't get any service. No matter what I did I have no service.
Yes I followed all the instructions, wiped everything, flashed the proper gapps and the kernel.
Since that didn't work I went back to my nand and still no service. Anyone have any suggestions?? Please help

On global cm9 rum through setup and change network mode to cdma/evdo becuz it defaults to gsm
I'm so fresh you can suck my nits...

Will give it a shot, thanks.

Awesome, got service back, but WiFi is still not working. It just forever searches and never connects to a network. Anyone have any ideas?

This happens to me sometimes and restarting my router usually clears it up, not sure if you have tried that, just throwing it out there.

I can't reset the router, I'm on a college campus. I have the latest firmware and radios,switched out rom after Rom and still WiFi doesn't work. Any other suggestions?

No data connection after flashing a new ROM? Look here for fix.

I experienced the problem of no data connection after flashing a new rom on my Optimus G. The phone needs to be reprogrammed, updating your PRL and Profile will NOT help. You must dial ##72786# this will start the handsfree activation and your phone will reboot a few times. It may take a few seconds in between steps of the activation and it will seem like nothing is happening. Just be patient and wait for everything to complete. When it is finished your phone's data connection will be working properly.

Some history,
I've been running Imperium and stockishv1 and v2 for a few days. I've made a couple backups along the way. About an hour ago I lost data. The phone works and makes calls, but my data is dead.
I've tried update profile and prl, and all I get is" Network error" I've tried this many times throughout all these steps.
I've restored backups, pre-Imperium and Stockishv1 with the same results.
I tried the procedure in this thread and still nothing.
Anybody have any other ideas? Would LGNPST restore the phones modem?

You guys need to read this. I am going to open an LGOG Issues thread but need to grab some food first.

I did, and responded in your ROM thread. Thanks
edit: Now all of a sudden data is working. BTW when my data wasn't working it still showed a flashing 3G. Sometimes. Both arrows on and off
edit 2: Also when data wasn't working, It kept wanting to roam.

saw the same thing on stock as well

Related:
I killed the connection optimizer while I was at work because I can't use work's wifi and listen to my icecast station I setup.
This killed my data connection and immediately put my phone into roaming. I rebooted like three times and finally my data came back (i also updated the PRL and the Profile, not sure which fixed it but something did)
From the things you guys speak of, I would guess the same issue is at hand.
ALSO: Stock rooted rom (non-deodex pure stock with bloatware frozen with titanium)

Try the G2 thread, I'm sure if you post in the exact same section over there you might have better results. General answer is that it is probably APN settings. Find an app, enter them, set it, and reboot (might not need to reboot).
