Samsung note 4 not getting anything more than 2G

Hey all im totally new to this and i apologise if this has been covered. I had a samsung galaxy note 4 and my darling kids thought it would be an epic idea to stick things inside the charge port totally ruining it and making the phone unchargable. So i contacted samsung repair center and was quoted a ridiculous price to repair and i just bout a new one to only find that its not an australian version i have a sm-n910k and my original one is a sm-n910G what can i do i cant get 3g i cant get lte i can only get 2G and minimal bars of service at that if anyone can help any advice atm is great advice thank you all in advance.

Go to settings/mobile networks and set apn settings manually depends on your sim carrier and country.
Just google your sim carrier apn settings and you will find easily.

I have already done apn settings and still to no avail i cant work this out for the life of me the only thing i keep thinking is that this model may not be compatible with my country as i know the sm-n910g is australia and the sm-n910k is korea i think ive bought myself a dud unless theres something i can do software wise idk any input is great imput though :/

Did you bought a new device, n910k or was it a replacement part? If you're comfortable, you can always change the USB port itself. I've done it for my Note 2 before. The USB port should be just a ribbon cable so you don't have to worry about soldering and stuffs like that. The prices are also way cheaper too.

Apparently the usb port is tricky to replace as its apart of the screen as samsung has told me and its a whole new device its the korean version im not sure what to do as the place i bought it from is a long distance away from where i live and i was wondering if there was a way i could install like the sm-n910G firmware to it. Im at my wits end with this and not sure what to do.

Oh right. I forgot about that. It was a simple plug out and in for my Note 2.
The issue right now is that the n910k, most probably does not support Australia's LTE bands. Hence the reason why you can only connect to 2G. You can check out gsmarena for the supported LTE bands for different models.
You can install a stock Note 4 Exynos firmware from another country with a carrier that uses the same LTE band as your carrier. It should be safe as some members here are able to install different firmwares meant for another device on their device, example N910G on N910F provided the CPU are the same.
Go to SamMobile, and find the firmware for Note 4 and you can see a list of Note 4 firmware available for download. You need to do some leg work though to ensure that the firmware you're flashing is meant for the Exynos version and the modem supports your carrier's LTE band.

No don't install over the n910g over your n910k. N910k is using a different cpu than N910g. N910k uses Samsung's Exynos processor and N910g being a Snapdragon processor. Idk what would happen if you flash a N910G over a n910K but I think it would be considered lucky if your phone would be able to boot up.
Your n910k should be able to run on another firmware meant for an Exynos processor like n910c. I just don't know if, after installing over your 4G would work because of different LTE bands. But this website says there's a chance it might work.

Usually in most cases, when a user accidentally installs a firmware meant for another variant, assuming they would get past the samsung boot up scene, they would not be able to get any network connections. This is due to different firmwares having different modem files for the different LTE bands. However if you were to install over a firmware with the same internals as your current device and more or less uses around the same LTE bands, it should work.

Here you go. It's every firmware ever listed. You need to create an account before downloading though and the download takes forever. You can install the firmware when your phone is in download mode using Odin via your computer.

You can try a random one. Preferably one without a telco. Example, N910C and not N910C (telco name). It shouldn't matter much as the difference would be that the one with a telco would come preinstall with the telco apps. Also, preferably from a English speaking country because usually the language would be based on country.
I would recommend you to download the original firmware for the n910k in case if this fails, you would be able to fall back to the original firmware.

Need help with getting TWRP and root on a Sprint S7 Edge.

I know this has been asked before, but it's been a year.
I have a friend who got themselves a Sprint S7 Edge. As far as I know the SIM lock is gone. Now he wants to get TWRP on it to be able to root it. I've been searching the internet for solutions and came over several guides that showed me how to root it, but no trustworthy recovery guide. The model number (SM-G935P/hero2qltespr) and processor are also confusing me. And as it seems there are no custom ROMs for the Sprint S7 either?
Im sorry if this thread is unnescesarry and Im simply missing something out or am too stupid.
All help is greatly apreciated.

there are 2 different methods depending on whether your phone is a exynos or snapdragon version.
which version does your phone say. Most us version are Qualcomm (snapdragon).
here is the link for snapdragon verion make sure it is the right one for your phone.

Its the Snapdragon Version. I followed the link but I noticed that the download link doesnt work. Why so?
Also, the guide I found linked me to the Exynos version of TWRP though the Model is the sprint one. Is it a mistake or right?

Doubt about product name

Hi there I have a doubt about the product name of my phone I have the F variant which is kltexx but I rooted my phone and I changed to kltespr and unrooted it later I wanted to root again and I realise that I changed the product name the question is can I root with the kltexx file or I have to download the kltespr to root my phone?

Boot in download mode and write the model number. That is the only sure way of knowing your model number.

I tried and in download mode doesn't say anything about model number in recovery is and appears kltexx klte but in phone info appears kltespr klte that's my doubt

Try to flash a klte rom. It should work. I can use klte, spr g900f

You've 'fooled' it to be a different model on the software side so that you can install apps which you normally can't but the hardware won't change. It's a klte and always will be even if the software says it's something else. If it used to say klte when you bought it then that's what it is

Frankenstein device

Hello everyone
I had Note 4 with Exynos chipset (N910C) with no brand (European version).
After some issues with LTE connections and SIM card recognition I have bought used N910F motherboard and installed in my device.
First boot shows that motherboard is from Italy device with Wind operator applications installed.
Next I flashed device but forgot to record IMEI, modem version and bootloader version.
I have restored device using Samsung Kies and during restore process Kies reported device as:
PDA: QG3
CSC: QG1
PHONE: QA1
After restore system setting shows:
Model: N910F
Modem: N910FXXS1DQA1
Version number: MMB29M.N910FXXU1DQG3
1) Now I have a problem: should I use TRLTE roms or TRLTEXX?
When I put "Note 4" in TWRP website search it suggest "Samsung Galaxy Note 4 Qualcomm (trlte)" - so it is TRLTE device?
On the other hand most of N910F images are tagged as TRLTEXX.
2) Can I mix TRLTE TWRP with TRLTEXX ROM image (and vice versa) or they should always match?
3) I have tested few roms and faced problems with not working camera. I know that latest official Android version for Note 4 was Android 6.1
and most roms (RR, Lineage) are based on Android 7.1 If this is the reason of problems? Because official Samsung kernel with working camera
supports Android up to version 6.1 and customs kernel used in 7.1 have some camera issues?
4) What is the relation between kernel version and Android versions? Its like Android 6.1 requires kernel 3.x.x and Android 7.1 requires for example versions never than 4.x.x etc?
I will be thankful for answers to my questions. I know that they may be naive for experienced users but I try to good understand the process,
rather than blind flash roms until device will work.

Your device is basically n910f now. You should use twrp and roms for n910f

Your camera is nonfunctional because Exynos based units use Samsung's ISOCELL modules, and Snapdragon devices use Sony's image sensors. Your network connectivity should be gone as well for that reason.

Ok, but still, if it is TRLTE or TRLTEXX because both tags comes with N910F roms.

By network connectivity You mean that antena design is also different and will cause signal loss?
I forgot to mention that I have also switched front and back camera to used ones from N910F.
From original N910C only body, USB port and scrren left.

Precisely. If you replaced those too, you should have no issues
Questions 1 and 2: Both use Snapdragon chips. Trltexx is the unlocked international N910F, while the other one is usually sold by carriers (T-mobile, AT&T and the likes). You should be able to mix 'em with no issues.
3: To get devices working on non-OEM firmwares without direct support from official drivers, developers write bundles of code called SHIMs. The camera is one such device, and because in most cases the driver is based on the manufacturer's own proprietary code, it's usually with blood and tears that our dear devs are able to get everything working even as it is. That's why you may face almost-working equipment with AOSP ROMs. You can read more about SHIMs here.
4: "If it ain't broken, don't fix it" applies here. There's no direct correlation between Android versions and which kernel versions they use, and manufacturers are sometimes slow to move to a higher version number because of how little meaningful improvements it brings. Recently, Google has mandated that all devices shipping with a SoC manufactured in 2017 or later must come with kernel version 4.4
Hope this clears things up. Anyone is welcome to correct if anything I've said is in the slightest incorrect. :angel:
Cheers,

UK-495 ROM's - Are there any?

Not sure were was the best place to post this, I have been searching for a while now and coming up empty on any ROM's for the G-Pad 8, model number UK495, this is the US Cellular version of the G-Pad 8.0. I have it rooted, but would like to be able to put a custom ROM on there if any are compatible.
Thanks.

Could you tell me what fastboot driver you are using to achieve OEM Unlock? I get the tablet into download mode, but it is not recognized correctly. I need to change the driver and am having trouble selecting the proper driver to assign. Is there a generic, universal fastboot driver? I've installed Android SDK and the Google Driver.
When it is properly detected, what should it say in Device Manager?
Thanks for your help.
