[Q] Help! Problems with lte and mobile neteork - G2 Q&A, Help & Troubleshooting

Hey guys, I really need your help now... I tried everything I could but couldn't fix the problem.
So, I have LG g2 d802, and I live in east europe, Georgia, near turkey.
I upgraded my phone with kdz to stock lp, i didn't like it, so i downgraded bootloader and flashed blisspop.
I don't. Really remember when it started, but right now I can not get lte to work.
Also, mobile internet and generally reception is really weird. It has some drops, mobile network most of the time doesn't work, and reception is bad and laggy.
I kinda flashed another modem, radio, baseband nothing seems to work. Or may be i didnt flash correct ones, and i dont even know which one is correct...
Please please please!
Anyone has any suggestoons?

[Q] i have a question and i'm confused.. plz help me

ok here it is. i've flashed various roms but don't really know what everything is, i just followed all those insturctions but never bricked my device..
I live in China, use 3g mobile internet, my phone is korean note2(shv-e250l), use slimkat 4.4.2 nightly, bandwidth MI1, kernel thor 2.9.
i've been using these for about 1 month, and there was not any big problems, except that it feels like my signal strength or internet speed isn't as good as stock rom
but yesterday, when I hung up after calling my friend, all of sudden my phone can't read my sim card, so i reboot the device, and my mobile network doesn't work, and i reboot again, finally everything works.
after that, everytime i call someone my phone goes stupid and i have to reboot it twice.
and I started to wonder, does my bandwidth need to be updated? can I use newest stock rom's bandwidth?
newest stock rom of korean note2 is NA1, will using its bandwidth solve my problem?
if it does the magic, how do i apply bandwidth of NA1 to my phone?

[Q] Data Drops During Calls. Please Help.

Hello guys. I have the n900t, I am now running tweaked s5 base n4 style v6.0. And I run alot of n9005 ROMS as well. With that said here is my issue. For only the past few weeks ( month tops) every time i make or recieve a phone call my data drips down to hspa. The second i hit call and right before my phone rings is when it happens. After my call the data takes a very long time to jump back up. This is a new issue and i have no idea what it is. However, i did flash back to a stock ROM and the issue was solved. And i forget which rom it was but it was soley TE based and there were no issues. I did try to flash a modem but it didnt take. Is anyone else experiencing this problem? Or can anyone suggest a fix for it.
Thank you for your help.
bump.

1) Quite strange - your picture suggests you are on Verizon yet you comment about a N900T in the forum for the INTERNATIONAL Note 3. On what network are you? Are you aware that there might be network-specific factors involved which could only be visible for other users on exactly the same network in exactly the same region?
2) Try stock ROM (with corresponding stock modem) from a location with very good signal.
5 he physical device is an n900t, however, I am running as of now, the hyper drive note 5 port with n4 UI. When I do flash back to a full stock TW ROM all is good, A FEW TW based ROMs seem to be OK. Like this one, the calls do not affect the data signal. But most ROMs do effect it in that way. You said that it shows I'm running Verizon?
But I am very curious why all of the sudden I am having this issue. I have never had it before. Except with a few specific AOSP based ROMs. I just can't figure out what it is that's causing it. I have done vigorous wipes of the phone to no avail.
And I am in Philadelphia so there really is no place that is actually bad reception (except in the susubways of course...lol)
And thank you for your reply.

1) Your avatar mentions Verizon for some reason.
2) If it is all OK with the stock ROM then it is a problem with the custom ROM, ask in the specific thread for that specific ROM. Most likely it has something to do with the modem and the corresponding RIL.
So when ever a new ROM is flashed the modem is flashed as well. Unless the dev says otherwise?

Lost Signal after Lollipop update

Hi guys
My phone was rooted but never flashed a ROM on it. Today I updated my phone to Lollipop through Kies Mac. After that my signal is not there. When I reboot the phone I get signal for few seconds then it gets lost again. Also phone never saves my Wi-fi connections.
I did reset my phone but still the same.
It was locked to Vodafone and I unlocked it in Vodafone shop when I first bought it do you think anything related to that?
How can I downgrade to KitKat or get my signal working?
Same here. Do any of you guys know how to solve this issue?

Please use the search function of this site and google, don't be lazy. There is a thread about downgrading . Also try flashing lollipop modem/bootloader, for this visit any of the TouchWiz Lollipop rom threads (like the one in my signature) most of them talk about flashing modems and bls.

[Q] No 4G/LTE in my LG G2 D802.

Hey guys,
As you can read in the tittle, my problem is that I don't have 4G/LTE I get 3G+/3G or HSPA+/HSPA.
Right I'm running Lollipop with the custom ROM, BlissPop with B14ckB1rd Kernel. I tried other ROMs (CM, RR, Paranoid) but I don't get 4G in neither of them.
I lost my 4G a quite ago, don't remember exactly how but I can imagine it was when I tried those early Lollipop builds, after that I went back to KitKat and the 4G was gone, even I tried going to full stock but neither that work.
I'm sure is a phone problem because I been with 2 different carriers and couldn't get 4G. The SIM card is brand new and today I spent around 2 hours talking with the Tech Support of my carrier checking everything is all right.
I also tried to change the Baseband/Modem/Radio (Right now I have Cloudyfa KK for the D802).
This might be also helpful for guess what could be the problem, when I dial *#*#4636#*#* go this phone information, down to prefer network type and select LTE only I lose service, by the way, in that configuration I have selected LTE/GSM/CDMA auto (PRL) and USA radio band.
I'm open for all kind of suggestions, If you need more information don't doubt in asking me.: fingers-crossed:

Well is good to know I'm not the only one.
Could you share more information?, like when and how it happened, so we can figure out what is wrong.
Today I'm going to try to get some logs, and check the system folder.
It happened to me with stock lollipop v30d vodafone ITA with another carrier sim (TIM). Solved after flashing v30a open ITA kdz.

I'm gonna try it, will send feedback as soon as possible.
Sent from my LG-D802 using xda Forum
No luck, I installed the V30a Italian version as you suggested but as you can in the screenshots no 4G at all, when I try to force LTE (This time with the command 3845#*802#) is lose service like in my last ROM, so I'm almost sure is hardware and not software.
Can some confirm me that, cause when you go back to stock by a kdz or how ever their is not residual imformation, every thing is fully clean right? Or some firmware just stay for ever?
If you guys have more suggestions that could try before I send it to somewhere for get it repair.

[Q] I9505. No signal when using 3G/4G. 2G works

Hi.
After updating Danvh's lolipop-rom to the latest version, I lost my signal and wifi. When I force my phone to use 2G (GSM only) in network-settings, everyting works normal.
But of cource I want the speed of 3G and 4G when using internet!
Sometimes (not often) 3G works.
Sometimes the phone says it has signal, but calls, internett etc don't work
I tried to flash the latest modem (XXUHOC6), but no luck. Have also tried modem XXUGNK4, XXUHOB8 and XXUHOB7. I tried to go back to the older version of the custom rom, but no luck
I have now downloaded the latest official stock rom from sammobile. But same problem with stock rom.
Any suggestions?
I have IMEI
Sorry, I have the same problem and I am still searching for a solution. And I have been trying everything as you and no solution. Sometimes I think is a hardware issue.
Very frustrating :S
Hope to find a solution soon.
I dont want to buy a new phone yet. There is no other phones out there that I want
