What QCN Stuffs?
My 801 on Cloudy is also having similar problems that it is not connecting 3G. 2G is working fine.
I thinky a clean reflash can solve this issue

I didnt tell you the whole story bro, actually this phone was sold to me as d802 . In settings->about , it was written it was an d802 but when i updated it to lollipop , there were touch problems in the phone. Then a guy named aftab (xda member) told me that your phone is refurbished and is actually a d800 (you can check your phone version by opening the back cover). Bottom line is this
1) check whether your phone is not refurbished i.e the version written at the back cover is the same as in settings->about
2) I dont know this QCN stuff that's why iam here !!!

Ohh ok. Refurbs have issues. You are lucky that it did not brick.
Mine is a T-mobile 801. My issue is something else. 3G was working very well previously. I just kept on dirty flashing new versions of the ROM as well as changing kernels as well, and now the 3G is not detecting at all.
Even if I do a network search, only the RAT: GSM comes and not the CDMA.
I think I somehow messed with the baseband. I can't clean flash again, as it has a lot of data. And I m very lazy in doing backups as well ☺
That is why was looking if someone can help me with the correct baseband that I can reflash without reinstalling the ROM to fix this 3G issue.

LG G3 AT&T D850 3G not working in Pakistan

I have recently bought a used LG G3 D850 AT&T model. The problem is that I'm only getting GPRS or 2g network instead of 3G. I have changed the "Preferred Network mode" to GSM/WCDMA/LTE auto mode but still to no avail. The phone is unrooted atm. I'd be grateful if anybody can help me!
I also have att d850.3g works great.make sure you are in 3g coverage. Because 3g in Pakistan is awful.and if c you are in 3g converge ,walk around your area to check again while using 2g.it will automatically switch to 3g.
Btw which Network are you using?

You can't upgrade it to stock marshmallow.as firmware OTA requires AT&T sim card to upgrade.
You can have coustom marshmallow.first root your phone and then flash any Rom for d850.

If someone brings AT&T sim for you.It would not solve your problem.As there is no service of AT&T in Pakistan. You can use Custom Rom like Fulmics till someone releases flashable Stock Marshmallow.
And yes,3g and 4g works on marshmallow.
My 3g is working on at&t g3 clody rom 2.5. Go to setting/Tethering&Networks/mobilenetworks/acesspointnames. And set up a new apn. Every SIM has it's own apn.

Well a few days back i got a used LG G3 AT&T showing software version D85010n in settings . It was already rooted (checked from root checker) with Kitkat 4.4.2. But when i rebooted it yesterday in recovery mode, it showed LS990ZV6 under Android System Recovery.
That means i got a converted G3....... Is there a way to install any custom rom in it? If so, which rom should i choose, D850 or Ls990? or should i avoid installing any custom rom in it?
I installed CM 13 rom in my LG G3 850 (020F) (from stock lollipop to Fulmics 6.1 and then to CM due to no data connection in Fulmics).. all is fine but the data connection only keeps to 'E', it never goes to H or 3G. .. the settings are right (APN set right for service provider, preferred network set to 3G) .. what could be the reason ? do i need to change the modem of 3G as wel ?

if u got ls990, cloudyg3 is the best rom i tried so far
1) first u need to root ( no need to if its already rooted).
2) then flash twrp via flashify or autorec.
3) download cloudyg3 (u can search for it here on xda)
4) wipe system, cache, dalvik, data partitions.
5) install cloudyg3 (make sure u check ls990 in aroma installer otherwise u will stuck in a bootloop)
thats it, all your problems will be solved, data will be working fine with H+
signals are good as i have tested on many ls990s.
i m using CM13.1 (android 6.0.1) on my LG 850 .. So far its doing good ... it shows E logo when data is enabled but the internet speed is good and reasonable ... so, i consider this E as 3G here in Pak.
The performance of this ROM is good / speedy and battery is reasonably well.
I hav lg g3 850 and my cell fon not shifting on 2g network if 3g network not availing and remains offlin to network iam using jazz and updated to 6.0
Any one tel me slution

How did you convert your D850 to 3G because I don't have option to change preferred network it's working only 2G please help. Its AT&T phone and I'm using zong.
I'm currently on 5.0.1 unrooted in Lahore and I don't have that network mode option in the setting so I'm stuck with 2G. Can anyone help please?

It automatically converts to 3g where 3g coverage is available. Btw you should try fulmics ROM. It's the best out there.

3G is not working in moto G XT1032(Single SIM) US version while using in India.

I have XT 1032 Moto G bought in US and i am using it in India now and it has not option of selecting preferred network between 3g and 2g in cellular network setting. I have checked all sim cards here in India only 2G is working.
How can i use 3G on it.
After Rooting and flashing other Rom(CM 13) , option to select preferred network will come or not?
Is this due to ,because this phone is build for US.
Plz help Me....Thanks in advance.
