[Q] Boost flashed no 3G when on custom ROM - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

My S4 is flashed to Boost Mobile. Whenever I install a custom ROM I get no 3G or 3G appears for no more than 2 seconds then its 1X. I nandroid backuped to stock and same problem so then I installed a Stock Deodexed NG2 Refitted ROM and right when this ROM boots Boost ID pops up it installs apps and puts it to my boost homescreen setting and my 3G and everything works fine. APN settings are the same when I switch ROMs so I have no idea what the problem is. I want to install a custom ROM like NegaLite but I am stuck at this point.

Have you tried using an app like apn backup and restore?
What are your apn settings on aosp? Are you on the latest modem firmware?

Right now I am on NG2 4.4.2 Stock deodexed NG2 Refitted ROM. This is the only ROM that my 3G works. My 3G worked on stocked rooted then I went to Negalite didn't work. So I nandroid to my stock rooted and 3G didn't work anymore so I tried this ROM i currently am on and it works.
My apn settings are all Sprint APNs and everything works fine and when I flash a ROM my APns are still the same but 3g is ****. I tried using APN backup and restore on this ROM it lets me disable ICS Check but when I install a different ROM that doesn't work so I can't use it. I even tried moving it to the system. I appreciate your reply

Are you sure it's true 3g on the refitted ROM. Sometimes it shows 3g but its really 1x. You can check under about phone status. 3g normally works for me as soon as I flash..no need to add apns. I only have to edit mmsc in APN settings to get MMS.

That's what usually happens to me. I installed Sac's ROM and everything works and I actually really like this ROM so I'm going to stay on here. I'm still trying to figure out how to remove this data stat notifiation or something on the top right and also how would I remove a NO SIM notification since I'm on Boost now I don't need a SIM

Every time I flash a custom rom I lose 3g.

Every time I flash a rom I lose 3g. I've tried all the touch wiz roms like wanam and pyrana and everything works except 3g. It goes down to 1x. I still have data just not the 3g speed. Any ideas?

hi to help you out here goes,
its more than likely that when your flashing roms this changes your baseband (ie modem/radio)
to fix this you will need to remember what the original baseband was prior to flashing custom roms (ie when it was stock rom)
if you cant remember try phoning your providor who should be able to tell you.
then simply find the corresponding modem here on xda and wheather its a cwm file (.zip) or odin file (.tar.md5) flash that and 3g should be restored.
however which network are you on and do you have a sg4 (reason being is that its an lte phone built for faster web speed so if your seeing a (dc or 4g) all is well.
also you may have your settings incorrect in wireless and network/more/mobile networks
Yeah I'm on the sprint network and have the 9505. So it's capable of 4g lte but that's not available here yet. It is in Detroit and when I've been closer to there I've seen it switch to 4g but it's always on 3g down here in Ohio. I think it's kernel related as I was messing around with the stock rom and different mods like transparent status bar and different toggle icons and I figured I might as well flash wanams new version of the Adam kernel 1.4 and I lost my data connection. On the stock rom. I restoredit and it was back.

cm10 internet problems.

I recently installed cm10 on my new s4 but the 3g speeds are really slow. WiFi is slow too. I saw a forum with the same problem with the HTC one. They said it was a problem with the baseband. Any help would be great because I'm not a huge fan of the stock os even though the internet runs great on it.
anyone know of any basebands that work. I would appreciate any help

You could always try to go to a Touchwiz Rom, update the prl and profile, and then flash back to cm10. I've heard that can speed up data a bit
You also could try flashing the MDL modem with Cm10...that might help as well http://forum.xda-developers.com/showthread.php?t=2338919

I don't think updating in the stock rom will have any affect since the internet on the stock rom runs fine. It's only after I install cm10 that the internet starts to bog down.

I did the odin thing and now my stock rom can't use wifi. When I enable it it says an app is trying to get certain permissions and wifi immediately gets disabled. It tells me to reboot the phone and I do so and same problem occurs. I did come to find that when on cm10 the internet does work but the play store and pandora only work on wifi. I get connection errors on 3g with those two apps.
Try to flash a custom kernel or flash a different AOSP ROM.

Not sure why the kernel would affect it. I was trying to find an aokp version that would work for sprint but couldn't find one.
It could help the WiFi issues because when my WiFi wouldn't work I flashed a custom kernel and it would work.

Oh you mean for the stock rom? I don't want to use the stock ROM if I can get the play store and Pandora working on cm10. The stock ROM is saying its a security issue and not just an error with the WiFi so I don't think that would help. The problem started after I installed the modem in Odin.
For both I also recommend checking out that ROM it seems like what you want in a ROM customization, AOSP, and the stabability of CM. Here is the link http://forum.xda-developers.com/showthread.php?t=2312063 if not check the original android development section it is filled with great AOSP roms similar to CM or better.

There is many cases that aosp roms/kernals have slow data speeds. The epic 4g touch was one. All aosp or touchwiz roms with non stock kernal had poor data speeds. This phone may be different. Im running tw rom with kt kernal and data speeds are the same. The prl/profile thing is huge not being able to update it in aosp can cause problems.
I installed pacman ROM and the gapps and Google play immediately stops working and a message pops up every 5 seconds and the internet won't load. I got Google to load once and that was it. I had to switch back to cm10.

I get this message on every ROM I install now unless I restore my cm10 ROM. When I restore my stock ROM WiFi don't work.

OK fixed the play store problem. The other day I enabled lte in data profile but my area doesn't have lte. I still have to fix the WiFi problem.

Awesome thanks.
Not sure what happened but the error is back

NO SMS

Hi guys I've had a on going issue that I though I would give another try at fixing.
I have unlocked my phone and am using a UK Vodafone sim and everything works fine when I use the stock rom
If I use an AOSP (I currently have slimbean build 2 installed) I am able to receive SMS but not send. I get the error "sending failed"
I have enable GSM using Xshortcut
I used HiAPN to get the APN
I'm using the MF9 baseband after downgrading then re-updating to get the unlock.
I have 3G internet.
Would it be possible to export the settings used in stock for SMS and port them to the AOSP rom?
I have tried using chopsms to fix the problem but that didnt work
I'm really out of ideas
All I need is to be able to send an SMS on Vodafone UK
Sorry for also posting this in the apps section as well. I cant see how I can delete it
fingers crossed
Thanks
Jamie
I ran into a similar problem when I used an aokp rom, check out my thread on the domestic unlock and look for nicotheandroidguy 's suggestions for aosp/aokp. I ended up just running sacs rom instead of slimbean
Also are you setting it back to gsm/umts AFTER you install slimbean? I found whenever I did a wipe and install I had to tinker again, reset to gsm, reinstall hiapn etc.

No mobile Data on Touchwiz

I have a SGH-I337M that I rooted with CF-AutoRoot and installed a few ROMs. I went back to stock for a bit and then installed a few more ROMS.
Now when I download my 4.4.2 firmware off Sammobile and install it with Odin, everything works, except my mobile data. My signal is good, I can send and recieve texts and make calls, but no internet. I tried setting my APN settings, selecting my carrier, restarting my phone, taking battery off and SIM, and still nothing. Not even Touchwiz custom ROMS work. it seems to be a TW issue. I have to keep CM11 on right now as my LTE works fine on it.
Anyone know what my issue is? My Modem now is NC1 with 4.4.2. Both with CM11 and stock. I tried calling Telus and they had no clue on their end. They tried refreshing my network profile and that didnt work either.

Install TW firmware and go to APNs then click menu button and then Reset to default. I had same problem and this little trick fix it.
Fixed it a different way. I used Odin to flash proper CS files but I ended up using the *#272#emei* method to switch to Telus and It worked perfect.

Good to know..

Flashing custom rom- does it wipe modem?

I recently switched from rogers to wind, and to do so, I needed to enable the two extra frequencies for penta band, which I have already done.
This said, I worry that if I flash a custom rom, it will wipe my modem and I won't be able to connect to wind's network anymore.
I do have a backup of the original via QPST, but would like to know before messing anything up.
Thanks!
Flashing a Rom does not touch the modem. It may mess up your apn settings though so if you have problems make sure they're set up correctly.
