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.
This video shows what I'm talking about.

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.
https://www.frequencycheck.com/compatibility/zYzu9/samsung-galaxy-note-4-sm-n910c/australia
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.

The u firmware is what you want. Just download the latest one... maybe pl2? It will unlock all radio bands. You may have to sim unlock it too. Root is unstable and still won't give you the all of the bands. The hardware is there, but the software controls them.

G950FD from Iran (THR) with pre-installed Persian/Iranian Calendar

I bought an unlocked G950FD which turns out to be CSC THR (part of OXM) so should mean it's from Iran. I have found it generic enough in almost every way to be used internationally (in English) with two noticeable exceptions that i'm trying to solve.
1) there is pre-installed Persian Calendar in the OS which appears after the Gregorian date on the AOS and lock screen. I also noticed this extra date appearing on the Samsung Calendar app under the western date, but i don't use this app at all so can easily ignore. The AOS and lock screen is seen all the time and would displays: "MON, JUNE 5 (KHOR 15)". I looked through every settings on the phone and many forums online, and there is no software way to turn this off.
I thought a potential solution would be to replace this stock ROM with another region since any of the multi-CSC OXM firmwares should be compatible with the phone. So I tried to flash another region using Odin. I tried Singapore (SIN and STH) and completely reset/wiped the phone two separate times. However, despite flashing a large (almost 6GB) file onto the phone it still remains in THR when i looked in settings. I guess I misunderstood the purpose of different firmware regions, I thought i would be changing my phone's existing firmware to another region and get a different set of default apps and localization behavior. But the Persian date is still there on all the same screens.
Am I flashing the rom incorrectly? Is there some setting that i omitted that would give me the desired result of a Singapore OS? Any other ways to change CSC and get rid of unwanted parts of a regional firmware?
2) Another problem is when i receive calls on my local sim card, the phone number shows up without the country code, but if i store my numbers (on Google contacts) in "+<country code> <phone number>" format then the contact is not linked to the incoming call.
Apparently this is fairly common with international phones being used in another market. There is a workaround where i can edit my numbers on google to not have any numerical country codes but instead use the flag drop-down menu on google to indicate country associated with the number. I'm ok with that solution but is there another way? Would flashing a regional firmware that is my location solve this? The region that i intend to use the phone is not part of the OXM multi-CSC list of countries since they only sell the snapdragon variant here.
I would like to find solutions that would avoid root and custom roms, but if that is the only option here, i am not against going down that route.
Thanks a lot in advance.

My eventual solution and what i've learned.
So as i described above, i tried to flash many different versions of G950FD or G950F firware with multi-CSC OXM, but never saw my CSC change from THR. Nothing changed on my phone despite installing large files through odin which was always confusing to me. For the record, i tried BTU (UK), STH (Singapore), and SIN (Singapore) which are all part of the OXM.
I learned from another forum that the sim-card installed matters, so i was just trying different non-middle-east regions by picking UK or Singapore but my actual home region does not support this model/cpu variant. I don't have a sim-card from any OXM regions, only Hong Kong and US ones.
Then i found an old Australian (Optus) sim card from a trip and found a G950F firmware version with CSC OPS on Updato. Not part of CSC OXM but same PDA/Phone version and was told it's safe to flash. When i flashed that firmware with the AU sim card installed, i got the AU OS and all the old regional apps were gone. I got some Australian ones but nothing i can't uninstall. My caller ID problem also seem to be fixed. So i consider the problem fixed.
In all of this, the PDA version numbers were always the same (AQDG), so i'm still a bit unclear as to what the CSC file is specifying and doing.
Am i correct to assume that multi-CSC OXM firmware contained regional apps/settings for all the various regions but without a sim card installed to tell it which one to pick, it kept selecting the factory region of THR? And when i flashed the Optus firmware, did i really need the sim-card installed? Would it have changed the firmware to OPS because it's outside the multi-CSC OXM group?

You live in Hong Kong, right ?
I do too, and have a UAE S8, and Samsung Pay doesn't work.
Does your working around things allow you to use Pay, or you get stuck on the splash screen as well ?

Yes i live in HK, so with the AU Optus Firmware I got a AU version of Samsung Pay with all AU ads and suggested businesses. I can get past the splash and login using my normal Samsung Account, which shouldn't have a region. BUT so far i haven't had any success adding any of my HK credit cards, i assume it's a version compatibility issue. There is no way to pick which regional version of Samsung Pay on the Play Store, so i guess it looks at your phone's origin to determine that part of the app.
I am not that keen to use Samsung Pay, but of course interested to know if it is possible. It says to call the banks to get my credit cards added, so maybe there is still a chance and i will post if i do succeed.
Do you think Samsung Pay is particularly good for HK? Would using Android Pay be comparable here? I'm not that experienced with mobile payment apps in the past. Seems like the membership card storage function will still work on my Samsung Pay so at least i have that and can slim down the wallet a bit.

Hey there buddy,
Finally found a thread that represents my problem also, in my case i have a s8 G950FD that shows the same thing on my lockscreen, by me it shows (KHOR18)!
Is there any way around it, i mean a fix?? I would greatly appreciate any help

Yes that's the Iranian calendar date so the day will increment everyday. Khor is abbrev for the current month.
Yes I have a solution (read my second post in thread) but involves flashing with a sim card and 950f or 950fd firmware of the same region as the sim card. You will need to reset and erase phone data.
If you need help flashing stock firmware there is a long thread on this forum and where I found the answer about how the sim card installed might make difference.
What region/sim are you currently trying to use your s8?

Hey there again,
Thank you very much for the time. I am in SE Europe, to be more precise Republic of Kosovo. My SIM is from Kosovo ( we are considered i believe to be in Europe carrier wise)
I do need help flashing the phone as i have no experience whatsoever i just recently switched from Iphone to Samsung, this being said i must also mention the fact that i would definitely need help. I dont want to mess up the phone i just got it like 2 days ago

Things to consider:
- You can flash both 950F and 950FD firmware on your 950FD.
- You need to find your desired firmware. And that region needs to match your sim card, use Updato or SamMobile but the firmware package is a >3GB file and takes a while to download. Make sure you only look for versions for model 950F or FD.
- You will need to download Odin and Samsung usb drivers to flash the firmware onto your phone. Follow the thread "OFFICIAL STOCK Firmware-update (Odin) thread Samsung GALAXY S8 SM-G950F" for the guide.

Yes, if you are changing country/code of CSC, then the system needs to recalculate the partitions.
And don't forget no short cuts! Every step should be done.
Good luck.

ooo man this things is killing me now the problem i have after i have rooted the phone is that the computer wont recognize my phone in download mode ??????????

Hey Peeps,
Small update on how things are for the time being. I have been following all steps as described with odin. Last night i had issues with my laptop not recognizing my phone in download mode, got rid of this issue by changing laptops. Once the procedure was finished i ended up with the same thing on my phone???
I have flashed a european software ( from france) but still no go on removing or changing the region!!!
To be honest dont really know what to do again help is appreciated since that date thing is really annoying

Any other way to get rid of khor on aod/aos
Went through the whole thread. Def not keen to flash or run csc. Any other way to turn off khor date from aod? Help !!!

Hey there all, again just a quick thank you for the tips and tricks. To be honest i dont really know what i did exactely but it worked for me.

Update SM-G935FD Dual Sim to Android 7 ?

I bought this phone from the USA about year and a half and I'm using it in Macedonia, Europe the whole time. It is a dual sim, but I'm not sure which country it is exactly from, Taiwan maybe I guess?
The model is SM-G935FD and the Baseband version shows: G935FXXU1APB6.
I tried updating it manually, but always says you're using the latest software version even though android 7 has came out a long time ago.
Can you tell me:
1. How can I update to android 7 ?
2. Why am I not receiving an update automatically, even though this feature was working when I bought the phone. I was getting regular updates automatically ever since I bought the phone up unti a point when the 7 came out.
3. If I update the firmware through an SD card or whatever method you suggest its best, will I continue receiving regular updates automatically after I install the v7.0 ?
4. How can I check what country is this phone from?
Lots of questions, would be glad if someone can clear these things up for me so I can understand better how this works with samsung and different countries models etc.
Thanks up front!

I'm sorry for my noobish questions, but can you please explain to me how to choose the country of my firmware? Do I need to choose a country which I currently reside in? Or do I need to choose a country for which the phone was made? I just want to use English language, even though I use it in Macedonia, Europe.
Please kindly advise. Thanks!

1. How can I update to android 7 ?
i had the exact same problem as you smart switch n ota both said i was on latest software. All you need to do is goto sammmobile download firmware for your s7 edge model if your phone is non carrier or unlocked then you can download any carrier version. after that download Odin n Samsung drivers n view an odin flashing tutorial on YouTube.
3. If I update the firmware through an SD card or whatever method you suggest its best, will I continue receiving regular updates automatically after I install the v7.0 ?
I am getting all the 7.0 updates.
4. How can I check what country is this phone from?
if i remember correctly Its written on the smartphone box although u don't need to worry about the country all you need to know is the model number.
But to tell the truth there is no performance difference only ui change but still if u want to be on the latest version then use Odin. good luck.
I have flashed my s7 edge about a dozen times n haven't faced any flashing problem just be sure to use original cable n try not to use the computer while the flashing is happening. use odin in adminstrator mode n if possible kill extra background processes like chrome etc (not needed but i still do it just to be safe)

Just checked my phone with PHONE INFO app and there seems to be no CSC code?! All these field are empty:
Original CSC Code: blank
Firmware CSC Code: blank
Active CSC Code: blank
Available CSC Codes: blank
CSC Country: blank
I tried dialing *#1234# and it says:
"USSD code running"
but it shows some kind of error right after:
"connection problem or invalid mmi code"
and does not enter the menu with the CSC code. Tried restarting the phone, switching sim cards and what not.. Nothing worked and I have no clue what my CSC code is now.
My original box is gone and can't really see what country it was made for, but as far as I can remember it didn't say anything on the box. The title of the original amazon.com listing says: Internationally Sourced (Middle East/Africa/Asia) Version G935FD which doesn't say much.
I don't know what to do, I'm a bit scared to flash it with just about any country firmware. There's got to be a way to find more about this phoe CSC?

Download cpuz app from play store. From the app you will find what is your phone chipset. If it is exynos download any 935fd nougat firmware and flash it with Odin.basically 935fd is a unlock version. it's support all csc version and you will also get update how much I know.

Samsung S8 G90f Wont connect to network!

hi all
i was advised by a friend to post my issue on this forum as someone here will always have the answer after searching the net without any luck.
i have a uk model s8 on the o2 network which was originally locked to o2.
so i took it the local market to get it unlocked which the market trader did and it accepted another uk sim
but wont connect to any network now. states emergency calls only, even with my original o2 sim.
i cant even search for any networks. when you try to search for networks by choosing the phone option, nothing happens, just states not available at this time. same thing when you try to choose manual or automatic search.
it accepts any sim now but wont connect to any network.
i thought it may have been barred even though i bought it 2nd hand and had it over 8 months so i checked imei on the net and it comes up clean. so not barred.
went back to market and the street trader said he will flash with firmware to fix. he said it was running latest firmware, android 8.0 dec 2018 G950FXXS4CRLB [december 2018, revB]
but will flash G950FXXU4CRL3 [december 2018, rev3]
but that did nothing. he said he wasnt sure why the phone is not getting a signal and confirmed it was definitely not barred.
he couldnt also understand why you cannot search network, why this option cannot be selected.
so this is where i am.
any help or guidance would be appreciated
regards,
Margaret acey

can anyone help?

Did you check IMEI online or wih the original provider sometimes online services don't show blocked imeis I have a US model rooted and sometimes the radio crashes and and have similar issues. I have to reinstall the CP and csc from the firmware files to get it back up. Using the latest Odin and firmware. I assume your on the latest firmware

thankyou for your reply,
i have not checked with network but i have tried multiple websites who offer imei checking services and they all show clean imei.
in respect of firmware,
it was running the latest firmware which was android 8.0 dec 2018 G950FXXS4CRLB [december 2018, revB] which didnt work
then the market trader flashed an earlier version, stil android 8.0 but two weeks earlier version, ending with CRL3 and that has not worked either. so at the moment its on that version.
both these were released by samsung in december 2018 but neither work,
so i dont know what to do.

I would take it back to the individual who unlocked it. It worked before and not after.

yes i did that but he said he did the unlocking and that has worked so is not taking responsibility for the signal. so i have to fix myself.

can anybody offer any help on what to do please.

Does it matter which mode you select? e.g. are you able to choose 2G/3G/4G autoconnect?
My S8 suddenly lost connection to just the Vodafone 3G network in Australia but is able to connect to other carriers on the 3G network fine.

it wont let me select anything, any mode at all.
when you select option, nothing happens, it doesnt go into that option.

ive have a message from a member on this forum, named "ZeroXO" who said he can fix this but waititng for him to get back to me.
he said he knew what the problem was, took my imei no last night and said he will get back to me. so hopefully he will find a solution for me.

Ok that's not even as far as I got.
I went back one firmware version to the one that I was running before the one that started developing the issue (although it ran fine for a week or 2 after the update) that didn't help.
I forgot if you tried to go back to an older one as well or tried one of the country specific ones. You need to check if you've got the snapdragon or the equinox version though.
Hopefully the other guy manages to fix your issue

Thankyou for your kind words and advice.
I changed firmwares a couple of times all 8.0.0 but no luck.
Ive got a member from this forum currently trying to fix it as we speak. He has made a lot of progress and clearly know his stuff and happy to have his help and assistance so hopefully it will be fixed today so ill keep you updated and let you know how i got on.
Thanks
margaret

Margaret.
