Hi All,
I am a G3 User from Singapore and my model is the D855. I've noticed that after rooting and changing to Custom ROMs I've only been able to get H+ and never LTE. Before when I just got my phone it was able to receive LTE.
What is the problem here? Do I have to flash some modem update or something? I'm not clear in this area so any help is appreciated!
I'm very sorry if I'm not doing something or doing something really stupid.
Thanks guys!
EDIT: By the way, I've selected LTE under "Preferred Network Type" and I still get H+.
Check the APN settings and make sure they're correct for your carrier. Custom ROMs don't always have the APN settings configured correctly.

HELP! 4g LOST / not working
THE SHORT OF IT: I flashed a custom ROM & kernel. They didn't work properly, so I flashed my nandroid to get back to rooted stock. NOW I HAVE NO 4G or signal of any kind (wifi works)!!!!!!
THE LONG OF IT:I'm in South Korea using the Galaxy Note 2 on the carrier LG with their U+ LTE service. As far as I could see and have been told my phone ONLY uses 4g (no 3g or other options to check). I was advised to flash a Tmobile or ATT Rom (I chose the Tmobile AOKP) as our U+ phones don't have their own Roms & Forums and I flashed a custom kernel from sjkoon a developer posting kernels that work for our phone. Others have done the same thing and reported no problems. After flashing, the new Rom & kernel, the phone booted in the Google startup helper I could not gain access to any signal or wifi to access or create a gmail account.
So, I nandroided back to stock (rooted, mind you, using chainfire's exynos exploit) but my 4g won't work, only wifi does. So, I have NO way to make/receive calls. I've verified a number of pieces of information through various avenues and have the following:
PHONE INFO
My Access Point Names says "LG U+" with "internet.lguplus.co.kr" underneath. There is no option to change it or edit it, just a radio button with no other options (is this is fine?). I was advised in another forum (http://forum.xda-developers.com/showthread.php?p=36895160#post36895160) to change mmsc's value to http://omammsc.uplus.co.kr:9084, but I dont' know where that option is to change it, or if this is a problem.
I also used the the "Phone Info" app and got some of these readings:
In Telephony, have a Device ID, my Network type is 3, Sim State 5, it shows I have a SIM operator and country, Serial Number Subscriber ID, etc. The only things that MAY be strange (I don't know what their original values should be) are that Call State, Data Activity and Data State are all 0 and my Network Operator Name, Network Operator and Network Country ISO are just blank. Even if I wanted to change any of these I have no idea how...
PLEASE HELP & THANK YOU!
It's strange. I spent the night/morning searching forums for a solution but not sure exactly what to do. Please, help me or point the way to fix this issue if you know how and thank you very much. I'm willing to buy you a beer or buy your newest app, say thanks on all your posts for the next month, whatever! Hehe. ...:crying:
I'm using the E975 and I've unlocked the bootloader, installed CM11 on it.
However I realised that the ROM did not detect any signals. I couldn't make calls or SMS.
I had to manually go to the network settings and find the carrier (Singtel) to register everytime I start the phone.
I then flashed savvy 4 ROM to see if the network was any better. It was, but then I was limited to GSM only. I couldn't get 3G or 4G.
Before I unlocked the bootloader, I had 3G and 4G signals.
Then I decided to KDZ back to stock ROM. I had network but only limited to GSM.
I realised my phone could only detect GSM signals from Singtel, M1 and Starhub. I couldn't see 3G or 4G.
I don't know what to do now. I need help. Must I flash any basebands or modems or anything? Thanks
Hello,
I flash back the correct KDZ file for my E986 (based on EMEI number) and I don't have 4G LTE? IT IS in the menu, but it never works. It's allways in 3G.
In this case, is it probably a hardware problem?
Thx

more like and apn setting. search in google your carrier name + LTE + apn setting. You should find the information to enter in tethering&networks>mobile networks>Access point names.
I don't want to disappoint you but I have tried anything the last month and nothing works, if you find any solution please let me know.
Hey all. I'm currently running a D855V (Australian model) rooted on stock Android 4.4.2.
So I recently upgraded to Lollipop but couldn't use it fully due to issues with some other software of mine. So I used the KDZ method to flash back to 10E. Since then I've lost all 4G/LTE on my phone.
I've tried changing the networking mode inside the mobile network settings from GSM/WCDMA to GSM/WCDMA/LTE but once selected my entire mobile network will drop. From there it will regain network connectivity for about 10 seconds (minus any data connection) and then drop off again, showing no network. It will continue to do this until I change the network type back to GSM/WCDMA or reboot (which defaults the connectivity method back to GSM/WCDMA anyway). I tried flashing the 10C firmware too (for Australia) but this will do the exact same thing.
I've also tried changing the LTE RAT settings inside the hidden menu to GSM/WCDMA/LTE and it still won't connect. It will drop the network like the previous method but will then reconnect only with a HSDPA connection rather than 4G/LTE.
I've checked the SIM card in another phone and it works fine with 4G/LTE. I've also checked my IMEI and it shows that I do have one so I can rule that out. Right now I"m at a loss. I'm thinking I need to flash a new radio or baseband but I can't find any info about that from any of the other threads I've read.
Any info at this stage would be great as it sucks having the 2nd best 4G speeds in the world and not being able to use them.
Cheers all.
EDIT: Resolved it by flashing KK modem/baseband. Thanks to JDr0iD for the suggestion. Turns out the KK and LP basebands are done differently. Figures considering the massive overhaul they've done with it. Anyway the modem can be found here - https://mega.co.nz/#!61QBVS5B!pa2xdGyeWAJKyAazkz9O8qc5b9hJOpxX5kaU_aFdjq4

Hey mate. Do you think modem is still linked to lollipop? Try another modem or restore EFS to see if makes a difference
Sent from my LG-D855 using XDA Free mobile app
think it might be an lteconfig issue?
I've bought a european market ZE551ML and have it on the metro PCS network. Every APN I've tried both T-mobile and Metro fail to give me LTE or 4g. I had a previous ZE551ML that was on the same network that had no problem getting LTE. WW firmware phone with 4.21.40.352 MM Installed. The phones rooted and bootloader unlocked. I can get hspa+ but LTE is the problem . Attached are the Screenshots from my APN and phone settings as well as random network Data. Im a network engineer with alot of experience and I've tried everything I can without success a little help would be much appreciated and would using a custom ROM help in any way.
Unfortunately after adding over 7 tinypic URL images I had to delete them cause This is my first post which im sure would have helped alot.
Anyways thanks ahead of time.
