[Q] Data network not connecting

Hi. Well I had rooted my phone and was running CM6.1.1 with snapdragon kernel. When the evo shift came out, I bought it and changed over to the shift. 3days in to using shift, the micro usb port failed and would not charge. It wouldn't even recognize when connected to my computer. So had to go and return it.
But when I changed over to evo, it started having problems with data connection. I could make calls but it would not be able to connect via 3g. It could connect through wifi but that was it.
So I unrooted my phone using .ruu and haven't tried it yet. Could you guys help me out and advise me in what option I have. Thanks again.

I had a similar problem when I had my hero....I lost 3g and ended up finding the solution was to wipe all, flash a sense rom and then go back to cyanogen....

Thanks. I'll try that and see what happens. I'll switch to evo tomorrow and see how it goes..

i had a similar problem with 3g data being very faulty after i updated all of my radios to the latest versions. what i did to fix the problem was full data/cache/dalvik wipe and then flash the radio: EVO_Radio_2.15.00.11.19, flash the wimax:EVO_WiMAX_27167_R01, and flash the PRI: EVO_PRI_1.77_003. Prior to that, i had the latest PRI and it would constantly screw with my data connection, so whatever you do, do not update to the latest PRI. Its actually been said that something weird is up with it and that this problem is common.
the radios can be found right here:

good luck man, hope this helped!

I have the same issue. I went from CM7 to a sense ROM and I still dont have date even after the new radio updates. Is there anything else I can do?

Have you already tried reverting back to your old radio that worked?

sure did. Nothing.

I actually did a full unroot using ruu. Then started my phone again back in stock mode. It worked after full unroot. Now I re-rooted my phone and back to using CM6.1.1 with snap dragon kernel.

Same Issue Please Help
Im having the same issue as the OP. I went from CM7 to a sense ROM and lost my Data connection. I can only connect through wifi. However I can't update my profile or my PRL This is a pretty big issue for me as I can't use any data features on the phone except when connected via wifi.
Can someone please suggest a way to re-establish my ability to connect to the sprint network. I do not have 4G in my area so I can't try that route. I have searched the forum for the last day and a half and still haven't found a solution. Ive tried reflashing the newest radios and still no luck. I have cleared the dalvik, cache and factory data reset mutiple times and I have tried sprint lovers newest ROm and also even tried reverting back to the original backup I took when I first rooted before I flashed any ROM's and still no luck. I also tried the ##3283#/MSL code/Data/ restore option and still nothing.
ANY Suggestions? Unrooting would be a last resort option followed by going to sprint and getting a new phone.

going to a sense rom, dialing ##data# and then entering your msl, then going to edit mode, top section, hit menu, and do a reset?
this usually fixes alot of data issues from what i am aware. It won't harm your phone anyway.

Yeah I have tried the ##data# restore multiple times and still nothing. It will reboot and begin the hands free activation but it never successfully completes it. Afterwards when I try to update profile it just sits in a loop saying "the network is preparing you services..." for 20 mins and then times out with nothing happening. I even tried the ##data# restore method again after reading this, for good measure, and still nothing.
Is it possible to connect via 4G and update my profile even tho I cant via 3G? I'm about an hour away from any 4G service I think Cincinnati may be the closest.
this is extremely frustrating and the worst part is that I dont know how it happened as I followed every instruction to the tee and Ive flashed mutiple multiple ROMS over the last 6 months and have had no problem until I tried going from CM7 to myn's warm2.2 rls5. After flashing the ROM and wiping EVERYTHING except the SD card I flashed the new Radio's (Cualkin's Combo pack with the newest Radios) and that's when I noticed the data connection was gone. I'm not sure as which step of the process caused the issue as I didn't notice it until I began to go thru the initial setup on the phone and was unable to connect to my gmail account.
I have backed up a few versions of rom's. Would they have the Data info I need and maybe a could just copy and paste a file or does this info need to be downloaded from sprint in order to setup the phone?
Please any advice??? I'd like to try all my options before I reroot and exchange it, If unrooting and returning is my only option can someone please point me to a good guide for the process? I used Unrevoked 3.21 for the root.

[q] lost my 3g

I can't seem to fix my signal after flashing a ROM anymore. only get 1x which is only better than no signal at all. At one time in the earlier releases of M.O.A.R I was getting LTE and 3G with no problems then later releases I've lost both. I unrooted and went back to stock and my 3G was back and rooted again, went back to MOAR and still no 3G. So now I'm on beenstalk and still cant get a signal. I love both of these ROMS hands down and would like to fix this issue without experimenting with every ROM in the forum. Has anyone else had this issue? I've resetted radios flashed different modems (except MK3) and I still end up with bad network. I need help

Open the dialpad, and then ##72786# . The Device will reboot a few times. Just let it do it's thing. It will go through the Handsfree Activation Process. This will reset your Data.

[Q] Sprint Note 2 LTE Issue

Hello there, I have been in the search for a perfect 4.4 ROM to work, I seem to be at an impass..
The 2 that I have tried, and Quite enjoyed so far are the Omni ROM and the Cyanogenmod 11
Both roms have the same issue, I cannot connect to a 4g LTE Sprint tower. I know the LTE Towers are working, My mom has the same phone, Sprint Note 2 and I have Mac's Rom on it and is picking up a very strong 4g Signal, yet my phone which sits literly right next to it, Refuses to get any 4g.. I drove around, went to known working areas, Never once did I snatch a 4g signal.
I played with the settings, it is set to LTE mode, I even tried Flashing as a fresh Install..
I tried flashing a Stock rom, but for some reason after it installs, and on boot up the phone does not work. I get a blank screen and literly nothing. I have to pull the battery to get it to turn back on. At that point I have to either Re-flash or restore a backup through CWM.
Any help would be appreciated, I miss my LTE Thanks

Same issue here. Not sprint though...

In cm11 set your mobile network type to cdma+lte/evdo or global. See if that works.
Next you can try to flash a touch wiz rom and do a hands free activation, verify lte works on the touch wiz rom, then flash to CM11 and see if you can connect to lte.

I have tried setting it to both. Global shows no signel what so ever on anything, I currently have it on cdma=lte/evdo and I just get a good 3g signal..
I might try that one out, Which is a good touch wiz rom to try and do that with ? I dont think I even tried a touch wiz rom yet

Personally I would recommend doing this:
Backup everything to your PC (both internal and external)
Delete the contents of the "0" folder on your internal card. If you use ES File Explorer, you'll need to enable root access, and then while in the app hit the menu button. The left menu will slide open and you'll see "Local".... underneath that you'll find the "0" folder. The problem is the way CM and Touchwiz mount the file system - they don't do it the same way. So when you do a factory reset in CWM, it doesn't clear out one of those folders. (I found this thread helpful - especially posts 2 & 4) I had major data problems on CM10 for 2-3 months, then I found this out.
After you do that go back to stock. Make sure you download the keep root file as well.
To play it safe, once stock, I highly recommend entering ##72786# in your dialer. The phone will grab the latest prl and update your profile. Whether or not you want to update the software (incl modem) is up to you, but I'd rather not get into the knox world.
Verify working gps. (I prefer "GPS Status")
Then go back to CM11.

I will try that out thanks

Update us on your progress.
If it works, consider hitting the thanks button - at the very least the guy in that other thread - I know I thanked him - his info saved me from going crazy!!!
I had working data (3g/LTE) on any touchwiz, but not on CM. It turned out that I had some corrupted data that wasn't getting deleted upon a factory reset. After I cleared out that data, everything was fine.
Hope your phone is back to normal!

Finally was able to download everything and run the tip, Thanks a lot dude! That helped and that did it ! I got 4g Back and everything is all peachy!!! Thanks again!

[Q] Data Connection Issues

Before I start let me explain I've searched for the answer to this and have yet to find any concrete answers. I've had my Verizon G'Nex since release and had it rooted before Best Buy had even run my credit card. I've been running SlimKat 4.4.2 Build 5 official and CWM Touch. Ever since I updated the ROM (clean flash) to the 4.4.4 experimental I've had problems with both 3G and LTE connecting to data. I have signal, in some cases "4 bars" worth, but it never actually connects to data unless I reboot the phone - that will last for a couple hours to a couple days then it's back to no data. I completely wiped the phone - data, cache, system, and sdcard...everything that CWM could possibly let you wipe - and then sideloaded the previously stated Slimkat which worked for months prior without issue. The problem still persists, and has gotten worse. I cannot use LTE at all. It will not connect regardless of what I do.
So my question here is what parts of Android affect data connection? Is this entirely ROM dependent, or does kernel have something to do with it? I'd rather not go through the trouble of finding another ROM that has speed and features of SlimKat, or randomly flashing kernels just to find it doing the same thing.

Well in not sure about this option being in your version of cwm.
However if it has wipe efs data as an option and you wiped it nothing that you do to try and fix your connections will work.
I found this out the hard way and had to buy a new gnex. Tried everything but couldn't get my efs data back.

No option about EFS. That's the thing that bothers me. I have voice and text, it can 'see' towers, it appears to be able to 'connect' to towers, but it's like it's not pulling an IP address or it can't contact DNS.

Network configuration corrupt with Cyanogenmod backup.

Hello, so here is my problem. I have been using Cyanogenmod 13 on my LG G3/ls990 for months now. Recently I needed a static IP address through Sprint. When they applied the static IP to my account, I was stuck on 3G, even though I mostly have LTE. Basically what I did was use an old stock rom backup to update my PRL/Profile. This brought back my LTE service. Then I reloaded my CM13 backup. Unfortunately, at first it didn't recognize my sim card, and then it only recognized 3G. Okay, so no problem, I decided I would just go back to the stock rom and clean install a new custom rom. Unfortunately, when I went back to the stock rom, it was also stuck on 3G and this time when I tried to update the PRL/Profile it didn't work, I am guessing because it already saw these as updated. So after a few chats with Sprint's tech support, I was able to get LTE to work again. She said a particular network configuration file wasn't working right, and she did something which was suppose to fix it. As instructed, I typed in code ##72786# after she did it, and LTE worked perfectly. Stupidly, I thought it would be as simple as reloading my CM13 backup. Yet it did it again when I loaded the backup, and now I am stuck on 3G again. Before this I didn't really connect the two together. Does anyone know what exactly is happening here? Tomorrow I plan to call Sprint again, to get them to fix the file, but is there a way I can do it myself, in case I have this problem again when I install a new custom rom? For example, if I go into ##Data# will I fix things by changing a setting in there or something? I hate having to talk to Sprint every time this messes up, and yeah, I know it was stupid of me to do the same thing twice, but it was a day apart and I forgot what I had done the first time. Hopefully whomever I talk to tomorrow can figure out what the woman I spoke with did, because she definitely knew what she was doing. Thank you for all of your help!

Update: Called Sprint they reset my network and I have LTE again. I am somewhat wary of installing a new rom but would like one for resolving performance issues and wifi tether. I downloaded an unofficial Lineage 15 Rom yesterday while I was on 3g only, but it couldn't find my sim. Is there a way to backup my current network settings?

Update 2: So I just tried a fresh install of Lineage 15 and it didn't work. First it recognized cell but no data. Then I went into data settings chose carrier settings that crashed, "android.com. [something]has stopped working" , the sim was unrecognizable after that and the carrier settings weren't there any longer. I backed up my EFS partition in the stock rom before installing, but then I was stuck on 3g even despite that. I called Sprint again, and got them to reset my network settings. Don't want to keep calling them though.
Anybody here with Sprint and a static IP that can recommend a ROM that will work and not mess up my network settings? I don't care if it is Marshmallow or Nougant, I just want something that doesn't overheat my phone and which I can have native tethering.
EDIT: I was able to install Fullmics and retain my LTE.
