Hi there everyone, I managed to install the lollipop 5.0.x on my S3 Spring running on the Cleartalk Wireless Network which is a local company. The ROM worked well and I had working 3G mobile data, except for the camera which we all know doesn't work for sprint s3's on 5.0.x ROMs, so i decided to flash to 5.1.1 from this website: GalaxyS3root under the sprint s3 roms, the 5.1.1 one.
Everything went well, i could run the ROM and everything worked, camera, wifi, everything, except for one thing, 3G mobile data. I get signal, but no 3G data, there is an exclamation mark next to my signal. Ive tried rebooting, and it hasn't worked, ive searched for apn fixes, but none of them are for the Cleartalk Wireless network, i've found
apn fixes for boost and others only, so after more google searching i found out you could backup your apn settings and restore them, how does this work? I really enjoyed the
lollipop rom and if it wasn't for the 3G not working, i wouldve kept it, right now i just decided to flash my S3 to the stock firmware 4.4.2 and just root it. Any ideas fixes or suggestions that could fix the mobile connection on the 5.1.1 ROM? 3G has worked in every rom, (Carbon, lollipop 5.0, stock rom) but not in the 5.1.1 one, any help would be appreciated! Thanks!

Same issue here.
I am on NJ2 baseband (modem).
finally found a solution!!!
for everyone loosing their 3G data after installing the 5.1.1 or any other rom... this is what worked for me... backing up apn's with "apn backup and restore" app from the play store in the stock rom ... then after installing the lollipop rom... just restore apn's. There are tutorials on how to do that ... just google for "apn backup and restore tutorial". :good:
I've been looking around for quite some time now and I can't find anyone with answers, so I'll try here.
I recently switched from Cloudy 2.5 to Exodus Nightlies. After setting up the rom, I noticed that I couldn't connect to data. I've had this problem before and it was always just an APN issue. So, I put in my usual APN settings and assumed all would be solved. Quite the contrary, there is still no data connection in sight. I've now cycled through every possible APN combination; toggled data, airplane mode, and LTE; tried "killall rild" command; and did a clean reflash of exodus.
I'm honestly out of ideas aside from a full reset, which I'd like to avoid if possible. I'm hoping someone here can offer some advice.
I'm currently using the following specs:
LG G3 international version (D855)
Exodus Nightlies rom (5.1.1)
Straighttalk service
Latest TWRP
Xposed
Thanks in advance!
I have the same problem after flashing stock v20u, i tried to flash also kdz or tot but doesn't change. How did u resolve?
i am with ringplus. today, suddenly i lost my cell network. can not make calls, other phones on ringplus seems to be ok.
so, now i need to flash a TW rom to update prl and profile. I saw the SwamMonster v3.0. downloading now. i suppose its KK. anyone know what must i do to downgrade from 5.1.1 to 4.4? thanks.
I'm on boost and lost all cell service when I flashed a backup I had. I just flashed the latest stock rooted we have and it's back up just fine.
it seems like a ringplus issue. been fix for a days. hope it will stick. thanks all
What is done:
first I flash 30B bump, the problems starte. then flash 30B LGUp, flash 21a and 21c, change band in ingeneering menu, delete lteconfig, flash 30b bump with modems: 21a, 21c, 30b hybrid, change of operator, manual config APN, manual search network. All this does not help.
Any ideas?
no ideas?
Idem.
But after reboot 4G is ok, but again...every morning i lost signal 4G...only 2G/3G is ok. So..reboot & 4G is up......disappointed.
Same on my G3. I downgrade from MM to LP but problem persist.
Same here....tried rollback to kitkat stock, LP stock, CM12, Cm13, and some other roms with no luck....have just flashed stock LP for repair...
so today I tried swapping my SIM with my friend's
he is using G3 with stock 21A, and his SIM is of the same carrier as mine
after swapping, I found that my phone (and of course his phone, too) is working normally
my phone is normal even after swapping back
did some different tests like switching on and off with 3G, LTE etc., everything is normal, at least at this moment
Still working with you? So it is sim card fault? With me after searching networks everything seems to be ok, but I couldn't connect with LTE. Only sometimes successfull connection.(once a day and after reboot same...) Very strange. :/
I lost network signal randomly... i tried with 30b hybrid modem, 21a, 21c... kdz method, twrp bumped rom... and doesnt help me at all.. my network signal gets a rotating circle randomly... and in that time my phone is out of coverage... it is .... hundred times in a day... i dont know what to do, please help
same here when i use sucks 30b D855, but now everything is ok with me.
Steps that have been followed:
downgrade to lollipop 5.0
install CandySIX Rom , then try to connect to my carrier network , at the first time it not give me anything , but when i reboot my phone , LTE appears and everything fine
back to CloudyG3 2.5 then i found that the problem resolved
My phone now works well
OKAY, i found a solution to the problem and here is what i found :

Same here...
Edited: Fixed this deletings the folder LTEconfigs on System/app
Had to then configure it to auto GSM/WCDMA then switch back to LTE auto
It connected at first with 3g then it went LTE and worked normally

Some people got their phones back to normal by flashing some roms (like CM, ACIP, stock, etc.), but that didn't work for mine
not sure if it was sim card fault, but my problem solved (at that time i was back to LP stock 20h) after swapping my sim cards with my friend's.
i am still using that sim card at this moment, working fine since last thursday
Same problem here, have signal drops on MM roms with LTE connection.
Tried all methods above, nothing really helps .. ;((
The signal is fine on LP roms, tho i installed N&N so i was able to change network type to GSM/WCDMA auto, having steady signal now, but missing LTE speed, trying to find solution to fix this, but unfortunately for now.
Same, my G3 doesn't recognize my sim sometimes or it just loses signal randomly, making the smartphone almost useless.
I tried CloudyG3 2.5 Lollipop, then upgrading to Marshmallow with many radios flashed (also the hybrid one) , then I tried to come back to a stock Lollipop ROM and the signal is always unstable. I'm going crazy due to that. I'm starting to lose hope too.
I think I've tried every possible solution to the connectivity problems I've read since flashing 30b.
Freezing LteConfigs gave me more stability, but didn't solve the problem completely. Tried editing the build.prop to force LTE as preferred network type, this didn't change anything. Don't even know how many times I've changed my apn settings.
Tried every combination of modems possible: 21a/c modem with 30b rpm/tz, pure 21a/c, pure brazilian 20c, brazilian 20c with 30b rpm/tz and nothing. Changed sims multiple times, didn't work.
The only way to get a reliable connection is to limit the phone to 3G... but that isn't a solution since I pay for unlimited 4G. If I let the phone in auto mode, the instant it tries to connect I lose all connectivity and it would take up to 2 minutes searching for the network.
I'll flash the stock rom today and if it doesn't work I can safely say it should be a hardware problem.

I had exactly the same problems I tried all of the solutions mentioned modems/roms/etc but what solved it for me was flashing the Pure stock MM kdz now no signal drops or 4g problems.

Did you root after flashing the kdz? I'll try with pure 30B but having no root is almost as bad as no 4G.

No not rooted it yet, to be honest I don't like the kingroot app it looks way too suspicious to me + the rom is smooth and stable at the moment so I thought I would stick with stock for a while.

just say thanks into that thread and vote to be able to other members to be sure that this helps. I am so happy that this method helped you. HF
So not long ago I bought my d855. I installed a few roms and everything was cool. A few weeks ago I installed the And7.1 Ressurection remix, but when I flashed the Fulmics rom after that, the mobile data wasn't working. I tried flashing many roms including stock with the KDZ method but with no effect. Today I noticed that in the mobile data settings, changing the connection to 2G/3G instead of 2G/3G/4G it suddenly started to work. Does anyone know what's going on with the 4G connection?? I tried flashing roms, turning device on and off, and installing the correct APNs. I use mobile data basically all the time and not having 4G is a problem to me. Thanks
I've had the same problem. I've sent my phone to LG service, they changed motherboard and everything is working now.
