Hope this isn't a noob question, I ain't touched android flashing in detail for a few years.
I have an LG G2 handset which I bought in mainland China (where I live), but is from Hong Kong as the G2 was never officially released here.
Anyway, I have got a 4G/LTE sim for it and as I expected, it doesn't work, just gives me 3G and after a quick google it seems other users have had success by flashing a rom specific to the region they will use the phone in. I have tried the 2 star/hash codes but neither seemed to work
Does anyone know my best option since I live in a region that doesn't have an official rom as such (although g2-lg.com seems to say theres a beijing rom)?
anybody throw me a few bones?! Getting desperate here!
Hi all
I managed to get ahold of an n910k note 4 but for some reason it doesn't seem to get LTE on the o2 network.
I am guessing it has something to do with band settings or maybe the modem, is there any way to change which frequency is being used so I can pickup LTE ?
thank you all
O2 onlu use 4G in 800MHz and the Korean version doesn't have this band...
You should have checked this before buying the phone.
Damn, there is no way to add it? Maybe someone could send me a different modem?

No way mate , i got SM-N910K korean version with LTE-A (lte advance) i live in uk i got 3 (three) sim card instide i can confirm is working the lte and 3g(hpda+ ) also but i got battery drain , phone is keep searching for korean radios , i got different baseband i got battery drain to much i can got only 2 hours of display on time
Hi,
I ordered N910C from Dubai which has the Baseband version N910CXXU1BOC5 which is for UAE . Now after some searching I have found a version for my country, Pakistan which is N910CXXU1BOE1.
My question is, should I flash my local version of firmware? Will that really improve anything, i.e. the battery timing, and communication etc? Or should I continue using the phone like this? I am getting average SOT i.e. 4 hrs but the signal reception is bad indoors.
Thanks!
@Xeeshu
Yes you can Flash....IF you are Not Rooted Yet Than Flash This Note 4 N910C Lollipop 5.0.1 N910CXXU1BOG1/N910CXXU1BOE3 .
Your Knox will remain 0x0 ...It'll not Harm your Device..
Regard Battery SOT it depends on Your Usage....& For Reception Mostly Different Baseband Not impact on Reception just Some Baseband Give Bad Receptions Because MODEm & Bootloader Drivers are Included in Each Baseband in Case of Samsung...So that's why Modem can impact on reception...
Check if your Signal's Reception is Good outdoors than its okay ...otherwise try Some Different Baseband...
Did you Try Signal Reception for Other Mobiles Than Note 4 ,How they Perform in Your Area?
It Maybe the Issue with Your Carrier ,Telenor Has Bad Reception in Mostly Area of Pak...So you should Check it...
I've SM-N910F came from Germany-UK...I'm not on original Baseband ...I Flashed many Others I've not seen any Strange/Bad behavior about Signals/Reception...
But when I used Deodexed version that was Not Stable Although Signal Reception is All the Time remain good...
Thanks for you reply but I am asking this because a friend of mine was getting less SOT i.e. the battery would drain quickly. He asked about my baseband version and when flashed he said it's very improved. He lives in UAE.
So I picked up a Note 4 model SM-N910C which is the exynos octacore WITH LTE. I am using it with Tmobile USA in Chicago. I get horrible horrible LTE signal. At my apartment I get .53 dl and 3-4 Upld.
When I first got it I went to about phone and it had arab emirates firmware lollipop. Ive tried at least 2 others and still get crap signal. i had a similar issue with a phone before and I fixed the issue by getting into a secret menu and messing with the lte and prl settings. This phone will not let me do that though. Do I need to flash a different radio? What can I do? I am doing the KIES recovery/reset as I type.
I'm facing the same problem here. I have a SM-N910C from mexico but the original carrier, Telcel, didn't provide android 5.1.1 so I flashed a rom from another country. The problem is that now my signal is really bad, when I'm lucky I get two bars but most of the time is just one or none. I can still receive and make calls outdoors but I loose service as well as data almost inside any building. I was wondering if I can solve that with some configuration or reflashing the radio but I'm not sure.
Could please anyone provide some help and guidance?
Thanks!!
I'm kind of newb at this S7 stuff, I'm more of an HTC guy. Yesterday, I bought an unlocked G930P (sprint) and am not sure, but think I learned that normally, people don't change out the ROMs to use a different carrier, they simply unlock the phone and live with the old carrier's bloatware. I started reading up, and first learned that TWRP apparently isn't available on a Snapdragon processor, so the G930A, G930P, etc, aren't candidates for TWRP. At first, I was kind of dismayed. Then, I found the G930U ROM and on a whim, I tried punting the G930U ROM to the G930P. I bought the phone off craigslist, and he said he didn't know where HE got it from, but it was unlocked. Anyhow, the phone took the rom without a hitch and now it looks like a U model...
My goal: Go with T-Mobile. Use Wi-Fi calling. Eventually have Nougat. Remove bloatware, but possibly keep some nice T-Mobile add-ons, if any, because I don't have their service yet (I hated ATT's crapload of stuff). Note this isn't specifically a "TMobile" question, substitute your carrier of choice for the questions...
Get to the damned question, you say? Ok, here goes:
1. I'm not going to ask any "do these bands work" when moving from a P model to T mobile. You guys seem to fight about that stuff until you can't type any longer. I'm going to assume what whatever bands work, that's what I get. Unless I get a T-Mobile specific phone.
2. But I will ask this: do the over the air bands it uses depend on the baseband ROM that is on the device? This is something I can't figure out.
3. I heard T-Mobile uses an updated boot kernel (3.0?) and ATT & others use an older boot kernel, and that if I move to T-Mobile boot kernel, I can't go back to any of the older ones. This process I seriously don't understand. Can I run a T-Mobile OS (or any OS) while using an older boot kernel ROM? I would think NO, right?
4. I don't like all of Carrier X's bloatware. I'd rather use a stripped down, cleaner ROM. I guess there are apps for that, but is it cleaner to do it with a stripped down generic ROM that I see floating around?
6. Speaking of ROM's - I saw a lot of Xetheros or whatever ROM's floating around, but it seems like there aren't any for the snapdragon-based ones. Is this true? The posts on this site don't really talk much about the snapdragon-based phones and why there aren't any ROMs for them, and why it won't work, and what, if anything, is being done to get around this. I guess the G930U is Samsung's answer to that, and allows fooling around with roms, but will the other phones ever be actually rom-able, or should I ditch this G930P and actually buy a G930U? Now that my phone THINKS it's a G930U, did that get me around some weird barrier and NOW I can update other funky roms intended for a G930U?
I'm considering selling the G7 I just got and going from a G930F (now that I'm a bit wiser). Any common sense why not to do that? I already HAVE an ATT G7 (not the sprint one I just bought), but it has a "bad signal". It gets only about 1 bar indoors, on a good day. I took it to a repair facility and they said, "nothing wrong with the antenna, it's your mainboard, don't bother just buy a new phone". Anybody have any advice on that?
thanks

All U.S. models are built the exact same and will all accept each others firmware if done right , so any unlocked s7 you put the U firmware will essentially be a g930u other than the number stamped on the back , I dont believe the U firmware supports wifi calling or VOLTE , There is a t-mobile nougat firmware floating around if you want to try that , your att g7 if it has a hardware issue should be under warranty but if your using it with a different carrier I would flash the appropriate firmware to it and see if that fixes you signal issue and if not put it back to stock and call Samsung , as far as switching from the international model , Well i bought a international edge as soon as they release and it took a crap on me within 4 months and I was unable to warranty it , that was my only issue with using a international model but also i dont think you can get wifi calling on those either . hope that helps
edit* and yes the bands are dictated by the rom , U firmware opens all of them otherwise carrier roms unlock specific , and T-mobile nougat dowgrade back to MM will be dictated by the baseband , I know the Sprint nougat can be downgraded but not T-mobile for sure

The U firmware does support WiFi calling and VoLTE on T-Mobile.

I guess us AT&T users just done get them features =/ , is it enabled or do you have to do something to enable those features ?

I don't believe those features are supported on AT&T (probably at AT&T's own request). Perhaps that might change in the Nougat version but I wouldn't bet on it.
