[Q] GT-N7105 Losing Mobil Network & not registering

My N7105 started with (Tre) HTS 4.1.2:
PDA: N7105XXDMB2
CSC: N7105HTSDMA1
MODEM: N7105XXDLL5
I switch provider and got the new update 4.3 from them:
Product Code: TLA
PDA: N7105XXUEMK9
CSC: N7105TLAEMK1
MODEM: N7105XXUEMJ9
After this i cant make any more calls. Or to say i can make 1 call after reboot and then it loses mobil network.
IMIE is correct and APN are correct.
I tried to see if there are any new firmwares for HTS Sweden but they havnt release 4.3
The wired thing is I still can surf the internet via 4G but cant make any calls or send sms.
Also my phone goes into roaming mode and things im somewhere else.
I have tried to change firmware to:
PDA: N7105XXUEMK9
CSC: N7105DNFEMK2
MODEM: N7105XXUEMJ9
and also:
GT-N7105 Galaxy Note II LTE
PDA: N7105XXUEMK5
CSC: N7105NEEEMK1
MODEM: N7105XXUEMJ9
But still same problems. I gone throw most of the forums here and found lots of information for N7100 but i need help with the N7105.
Please can anyone help me or refer me to right patches or firmware i can use to be able to make calls again.

I have now also tried flashing several modems:
XXALJ3 (Sweden / Telia) N7105XXDLK7
XXDLL4 (Sweden / Tre) N7105XXDLL4_modem_HTS
XXDLL7 (Sweden / Tre) N7105XXDLL5_modem_HTS
XXDMC3 (DNF) N7105XXDMC3_modem_DNF
Installed also DN3 V3.2 Rom.
Still same problem. Lose my mobil registration and can use the internet. (Not throw Wifi, but APN setting)
Getting frustrating not nowing what to do or try.

Bump

Finaly got kies to backup the firmware to:
Product Code: HTS
PDA: N7105XXUEML2
CSC: N7105HTSEML1
MODEM: N7105XXUEMJ9
BUT still same problem.
The phone seams to be connected with the operator as i spoke with the operator and they can se it. But i cant make calls or send sms.
Its like the phone is stuck on 4G.
I have tried to change to GSM only and more but still no luck.
Anyone out there that has the same problem as me?

i had nearly the same thing on my N7100
let some one call you , it heard the ring tone but your N7105 didn't ring , then you should use Z3 to rewrite your IEME number

There is no ringtone. Plus IEME nr is correct and sending right info to new peovider. Its a software problem thats for sure.
As the roaming is turning on all the time im starting to wounder if its the Region lock thats playing around. As all 4.3 have now recieved regional lockes and to unlock it you need to put the origanal sim provider to unlock it and after that you can use any provider. Have ordered a prepaid card from the original provider and will try to start it up to se if its regional locked.

[Q] Install 4.4.2 from Sammobile manually

Hi All,
Got a small question about upgrading my S4Mini (GT-I9195 LTE) from 4.2.2 to 4.4.2.
At the moment my phone is on stock-rom which is 4.2.2 , when i check for 'updates' it says, 'latest updates already installed'.
Also when connecting to 'Kies' , the program says latest firmware already installed..
However when i check the Sammobile website for the GT-I9195 Model there are newer firmware's showing up , Android 4.4.2, but it depends on the country if the firmware is already at 4.4.2.
For the Netherlands, where i'm from, this one is available :
Model: GT-I9195
Model name: GALAXY S4 mini LTE
Country: Netherlands (Vodafone)
Version: Android 4.4.2
Changelist: 1646188
Build date: Tue, 27 May 2014 08:17:05 +0000
Product Code: VDF
PDA: I9195XXUCNEA
CSC: I9195VFGCNE4
MODEM: I9195XXUCNEA
However, i'm not with Vodafone as a provider, would that be a problem ?
When i check my phone specs, this is what i get:
AP: I9195XXUBNB3
CP: I9195XXUBNB3
CSC: I9195PHNBND1
Can i just install android 4.4.2 from Sammobile without any problem ?
Thanks in advance.

Network/carrier specific firmware may have custom software or setting for the ROM, it better to find some other model that are as close to your phone's spec as possible to avoid any potential problem.
As if your phone has Know, it would trigger Know if you don't update via the official way.

Hi, thanks for your answer.
Knox-flag is already triggered on my phone, but because i had to sent it back to shop for maintenance they reset it back to factory settings (android 4.2.2.)
However, i don't get it the way Samsung is updating the phone's. It's said that 4.4.2 is out for S4Mini , however when i'm searching for my device on Sammobile (I9195XXUBNB3), it still says 4.2.2.
Should I wait with updating, or what else ?

That depends entirely on you... If you wish to preserve the warranty and keep the KNOX, than don't. If you can't wait and don't get bother by KNOX or warranty than go for it.
LOL, too tired, I just realize I keep typing KNOX as 'know'...

I just typed that my KNOX warranty is already void, it's triggerd 0x1.
I'm now just wondering what the best way is for me to update to stock 4.4.2...i'm confused with al the stock-roms that have 4.4.2 for S4Mini on Sammobile.

All the ROM listed on Smmmobile is for different region. And I would also expect there won't be a 4.4.2 for your specific phone since you've check via Kies. So you need to find a phone from another region that are same spec as yours - band, function, etc and prefer not a carrier/network model.
Alternatively you can go for the custom KK ROM here.

ATT Firmware for S20+ so I can get Wifi Calling

Hi,
I am trying to find the correct version of firmware so I can flash it to my unbranded unlocked S20+ (SM-G986U1).
I flashed using Odin the following version:
PDA: G986U1UES1ATG3
CSC: G986U1OYZ1ATG3
downloaded from Sammobile with a date of 8-3-2020 and all it did was ad a purple theme. Still the phone does not show the wifi calling buttons. I had already registered my EMEI with ATT . Am I missing something?
Any help will be greatly appreciated.

CSC mess... why has it become so difficult?

Hello Community,
I have always bought factory unlock international versions of Samsung galaxy S phones from Amazon and used it outside the US (in Central America). The last time I flashed a phone was in the Samsung S4 period where a few friends had carrier branded phones, which I helped them unbranded by flashing the TTT (Trinidad and Tobago) firmware, since the PDA and CSC was the same as mine. It never gave me any issues and therefore, I never really messed with CSC before. It was easy and simple!
I recently returned to Samsung ecosystem but this time I bought a S20+ (SM-G985F) carrier branded and locked phone (Claro Guatemala). It's clear that things have gotten way complicated now.
Version: G985FXXU3ATG4 / G985FOWA3ATG4 / G985FXXU3ATG4
CSC: PGU
Thanks to another post, I was instructed to able to flash a different firmware to unbrand it. I was also instructed to change CSC to GTO, so I would not loose VoWIFI and VoLTE. Apparently now just flashing the firmware does not change the CSC, there is another process for that. I performed the change but still lost the options (although my carrier still doesn't support it).
version: G985FXXU3ATG4 / G985FOXM3ATG9 / G985FXXU3ATG4
CSC: GTO
I've been trying to understand how CSC works but I've been reading several contradictions. Some say that if CSCs don't match you might not get OTAs. Other say that that doesn't matter. Why couldn't I just flash the TTT as I've done before? Why did I have to change my CSC to GTO? What if I change my CSC to TPA but use it in Guatemala, would I still get OTA updates? If my device is single sim, why does my CSC GTO/GTO,GTO/PGU as a dual sim?
Who can give me a definite explanation on how to choose a correct CSC firmware? HELP!

I'm going through the same nightmare...

Isn't the SM-G985F a Multi CSC device? Try this, go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press dial, you should see a screen with the list of available CSC codes for your device. Select the CSC that you want and tap the Install option.

I'm also new to the CSC concept, and have been looking into its function. I would recommend checking out these links for a good overview.
(I'm a new user and cannot post external links, you'll have to use a search engine to find these. If a MOD wants to change these to links, feel free!)

What follows are my findings and my attempt to 'put it all together'.
Samsung Firmware Naming Convention
See [10] and [11]
What is a CSC?
Samsung CSC refers to the Country Specific (Product) Code. This identifies the region and carrier for which the device is configured [1,3].
This includes [7]:
Carrier branding: A CSC may be country or carrier-specific. Samsung releases the same model of a smartphone to Tab with different CSCs. For instance, if you use an unlocked or unbranded Samsung Galaxy phone in the UK, its CSC would be BTU. However, if your device is locked to a network operator, it could be VOD (Vodafone), TMU (T-Mobile), ORA (Orange), XEU (EE & Three), etc.
System Languages: These include the availability of the popular languages used in a geographical area. For example, if you own a Samsung phone in Mexico and flash the firmware meant for India with INS as CSC, you won’t be able to set Spanish, Nahuatl, or Mixtec as your phone’s system language and keyboard.
Localizations: Samsung ships its devices with geo-specific or bloat apps relevant to a country or region. Localization also determines the calendar settings and local festivals.
APN Settings: Access Point Name settings include all configurations to make a mobile device work with the network carriers of a region or country. Without these configurations, you may not be able to enjoy seamless GSM, GPRS, 3G or 4G mobile networks.
Samsung FUS: CSC also contains key info to help Samsung’s Firmware Update Server to connect to the correct update channel and roll out the proper software update to your Galaxy device via OTA.
Deep dive:
Historically, Samsung had one CSC folder on the device [8], located at /system/csc. This folder contained different XML files used to configure the device.
Code:
/system/csc
features.xml
language.xml
others.xml
customer.xml
The supported configuration options for these files have been extensively documented by other users [9].
Presently, there are two flavors of CSC files CSC and HOME_CSC. Flashing CSC performs a factory reset of the device; wiping all third-party apps, data and settings [7]. HOME_CSC is used to reinstall the firmware or updating the system, retaining apps, data, and settings.
Examining the current contents of a HOME_CSC file shows the structure has changed.
Code:
HOME_CSC_OMC_OXM_G985FOXM3ATG9_CL18862671_QB33041563_REV01_user_low_ship_MULTI_CERT/
meta-data
cache.img.lz4
optics.img.lz4
prism.img.lz4
The three image files correspond to directories found on the device root (using adb).
Code:
/cache/
backup
backup_stage
lost+found
lsb
magisk
magisk.log
magisk.log.bak
recovery
/optics/
configs
/prism/
HWRDB
app
etc
lost+found
media
priv-app
sipdb
Buried within the optics folder, we find XML files similar to the original design.
Code:
/optics/configs/carriers/single/TPA/conf
cscfeature.xml
cscfeature_network.xml
customer.xml
omc.info
How do I find and interpret my CSC?
You check your CSC by going to Settings > About Phone > Software Information > Service Provider SW Version. According to [1] you should see the following, depending on your phone's SIM capacity.
CSC Format:
AAA/BBB/CCC (Single SIM Models)
AAA/BBB,BBB/CCC (Dual SIM Models)
Click to expand...
Click to collapse
Where, according to [5]
AAA is the current CSC
BBB is the recommed CSC for your SIM (if this CSC is inside your current Multi-CSC)
CCC is the factory CSC of your phone and can´t be changed
Click to expand...
Click to collapse
Some phone info applications call these the original (CCC), firmware (AAA), and active (BBB) CSCs. For example, my SM-G985F shows
Code:
SAOMC_SM-G980F_OXM_TPA_QQ_0006
...
TPA/TPA,TPA/TPA
Which tells me that the phone was manufactured for Panama, has the Panama firmware and the recommended SIM CSCs are both for Panama. I know this because the list of CSC country codes is well documented [12].
NOTE: I came across multiple sources online that say the SIM CSC will change depending on the SIM card you have inserted. For example, [1] states
When you switch to a SIM card from a different country, your device will attempt to modify the SIM CSC. If the operation is successful, you’ll receive a popup asking to align the new information with the active CSC. This will effectively modify the configuration region, but the process requires a factory reset.
Click to expand...
Click to collapse
But this may not be true. I am in the USA using a local provider and was never prompted as described.
What does each CSC do?
So we have the three different CSCs, each of which could be responsible for configuring different parts of the phone.
Firmware
SIM
Original (factory)
I would think that the original CSC is only there to identify the original factory firmware, and is not configuring anything on the phone. The firmware CSC should tell me the current firmware loaded and the SIM CSC does ???
I will continue to look into this over the next few days. If anyone can contribute more information it would be very helpful.
