Hello All,
A couple of days ago my D800 went from 4G LTE to the Edge network. I spoke with the carrier to no avail, tried different towers by going to different locations and will not change from Edge. I went into the menu to try and change the band and the selector is stuck on Set GSM/UMTS band with no drop down option. This mobile was purchased factory unlocked, did not do any roots or any other custom changes. Did a reset - factory restore and did not help.
Any ideas as what to try? Thanks in Advance....

I have a i9505 running 4.2.2 (UFNB8, DBT CSC) stock, non-rooted. My problem is that I still can't get LTE/WCDMA to display as an available option in Network Mode. Operator is Telenet (MVNO, Belgium). I am in a 4G area, according to the operator my SIM card is 4G capable and my IMEI has been 4G activated. According to them I should be able to connect to the LTE netwrok, but no go. They advised factory reset but I don't want to do that for now as I am not sure it will help. I remember seeing LTE as available when I roam (in roaming my MNC is different though).
Any ideas (apart from rooting and forcing LTE radio on?).
How does the 9505 decide when to turn on the LTE radio? Is it based on getting an LTE signal or is something defined on configuration file level per MCC/MNC...?
Cheers.
OK, I should have searched more. But for future generations' sake, apparently there are two possible reasons:
1. Need a factory reset (still don't understand why?!)
2. Your phone's CSC is not supported on your current carrier's network (apparently this is checked and there's a whitelist of some sort)
In my case it was 1 - I reset and now LTE/WCDMA appears.
Cheers
I recently bought an unlocked N910S but I seem to be having some problems with LTE (I live in the US) and can't seem to access the network mode menu in 'more networks' (the option is grayed out).
Some things I've tried:
Added the access point for my provider (Cricket/AT&T)
Booting in safe mode (no changes).
Flashing other regions' stock roms (N910T, N910V, N910T); Odin gets stuck at NAND wrtie start and only N910S stock rom seems to work.
Accessing Network Mode settings through the hidden menu (can get LTE if LTE17 or LTE All is selected but can't make or receive any calls).
Any help would be appreciated.
Thank you.

Using ATT LTE now. Stock rooted to remove a bunch of Korean apps. Use band 5 preferred in the hidden Menu. Band 17 also LTE but couldn't make phone calls. ATT LTE band 2, 4, 5, 17
EDIT: SOLVED... In Dual SIM settings, the Network mode was set to GSM only. I switched it to LTE/WCDMA/GSM mode and now I have LTE again. I guess GSM only was set by default?
My phone no longer accesses the T-Mobile LTE network, rather it only stays on EDGE after I flashed DrakenFX's B29 build bootstack and system files from the thread "[ROM/GUIDE] Full Updates / Back to Stock Files via TWRP (A2017U, A2017G, A2017)".
Strangely, the phone shows two T-Mobile default APNs, and I don't know why they are on there! I'm using an MVNO (Ultra Mobile, on the T-Mobile network). These T-mobile APNs can't be deleted as there is no option to delete APNs in the menus. I've tried all four APN settings offered by the Ultra Mobile tech support line, and they all give EDGE data. My LTE data was working fine before I unlocked the bootloader, rooted, and flashed B29. Everything functions perfectly besides the mobile data.
Any ideas? (XDA rules say I can't post in the development threads).
Hello again. I decided to buy 2 sprint branded phones. One came sim unlocked. I used the NV method on the other. On both I can place calls, but data says disconnected. The APN's were downloaded straight from the provider (att mexico). And I compared the apn setting with a working M8 with the same sim.
I have tried full reset, and changing prefered network type in *#*#info#*#* menu. All it does is say disconnected. Am I missing something?
Update: got it working by flashing a custom rom. I used viper (selecting unlocked version on carrier select screen)
Hello All,
For the past 3 weeks, I was reading threads and trying to solve the issue, but no luck. So please help me.
My problem/story started when I have ordered an LG V20 US996 from china, everything was working. I wanted to root it so I have tried this https://forum.xda-developers.com/v20/how-to/v20-h915us996-dirtyelf-bootloader-t3568013 and it worked, but I have lost the GSM Signal
I have tried to fix the issue by going to *#*#4636#*#* -> Phone information, but the US996 rom can’t access this menu. So I have tied to flash LineageOS for US996 it has started but the touch didn’t work so I have used an OTG Mouse, I went to *#*#4636#*#* but no result
After a long search on the internet I have come on a thread that suggest to see the original model of the phone (because as they said in china they may change the phone version), so I have checked the motherboard and I have found out that my phone is VS995.
But when I enter the LGUP or UPPERCUT it says that it is US996, I only can flash US996 KDZ ROM. However, after I went to ##PROGRAM996 I hit there reset (I don’t know exactly where) the phone restarted and now it shows in LGUP that it is VS995
So I have flashed using UPPERCUT VS99512A_06_1114_ARB00.kdz and no result still no GSM Signal then I have rooted the phone using https://forum.xda-developers.com/v20/development/ls997vs995h910-dirtysanta-bootloader-t3519410
I have flashed back the original EFS, no result still no GSM Signal
So I have Installed LineageOS for VS995 in order to access *#*#4636#*#* (because I couldn’t access any hidden menu form the VS995 original dialer) after Installing LineageOS the touch screen didn’t work I have an OTG Mouse, I went to *#*#4636#*#* -> Phone information, I Turn on the Radio but the still no GSM Signal
I have tried flushing multiple kernels and ROMs but no luck
I even tired this https://forum.xda-developers.com/v20/how-to/manual-program-sprint-ls997-v20-t3557676 but no luck, I couldn’t contact Verizon for the MSID number because I live in Lebanon
P.S: I have an IMEI number
I am going crazy here
Please help me
i have also tried this https://forum.xda-developers.com/v2...-ls997-v20-t3557676/post71315675#post71315675
and didn't work
i have no signal problem too, after doing firmware update using wifi, now my VS995 won't register to GSM/LTE network and it says Sim Card is not from Verizon...
how to activate this phone? i'm not in USA as your problem i cannot activate the VS995 using Verizon services,..

Mine was showing no signal until I made a call, then it worked. I'm in the US, though.
