[Q] Baseband Version: Unknown + No Network

Hello guys,
I got a Galaxy Note 4 SM-N910F (Retail Unit) from a friend, I flashed a stock ROM to get rid of the Retail Mode but now I have Baseband Unknown and No Network. Is there a way I can fix this and use the device Normally??
I would really appreciate any help..
Edit 1: The Phone IMEI Number via *06# shows Null Null and under about phone, IMEI Number is also unknown.

If you sure you have right firmware for you're Note 4 "910F" flash again with Odin!
Set Odin by default! Tick not RE Partition and so on!

Does that mean it cant be used normally with a SIM Card, just Wifi or is there a way I can get it to work?

You have an app "Samsung Retailmode" in your appdrawer?
So open Configuratin Settings in this app, than you have to enter Admin Passwort! Enter 1. Password : 5444
After this disable the factory...... here you need second password! 2. Password : M729Q16K8546
After this check reset and reboot! Hope that helps!?

I already removed the Retail Mode App from the phone and flashed a stock ROM, but I cant get the SIM card to work and access mobile Networks (Baseband Version: Unknown). I would like to fix that and get it working normally, (maybe flashing some different Modem or Mod to enable network access) but I don't know what to flash or how to do it. :crying:

I know only the method with Unlock from RetailMode App!
Maybe it works when you flash Retail Firmware/ Install Retail Mode app and try it with the passwords above?
You can download retail mode app from playstore!
if you have a live demo unit you'll never can get it work, so there's no hardware (modem) inside

What stock ROM did you use to flash, and what is your device's info?
Can you show the device's info with this Phone INFO ★Samsung★ app?

I just found out I have exactly the same device = tablet. I'm kind of dissapointed.... ;crying: Can I at least sell it for spare parts? If not I'll just use it as a tablet. I was cheated by the seller. he didn't say anything. Great app btw. will use it from now on...

As you can see in the screenshot, there is no info about Modem Board, so I doubt it does not have modem hardware (?).
Can you show me all screenshots from that app? (you can use S Pen to capture screenshot easily).
And also can you show a picture of the back sticker (behind the battery).
Thanks.

Nothing ?

Same thing happened to me too,but before that I had a fully functionaly phone.After I flashed many custom roms ended in bootloop and only a stock rom NEE 5.0.1 works,all other stock rom I flash ends in bootloop.And baseband unknown,imei null,no modem.

I think from Note 3 onwards, samsung has choosen to make separate hardware for its demo devices. In some specific models even the AMOLED panel also is unique and can't be used with other devices. I am currently working with samsung. Earlier we were using these demo devices for personal use and for spare parts. Right now it's good for nothing other than playing games and surfing Internet.

difference between flashing ... ?

hello people
i have this samsung s4 i9505 which i think is not genuine , i think it's koren. its stuck on boot screen and i want to flash it . so i want to ask what is the difference between flashing a genuine android phone and koren android phone . any kind of help is appreciated

Try entering download mode by pressing volume down, home, and power at the same time. If unable to enter download mode your phone is a counterfeit. If you can enter download mode you'll have a model number, which we can use to point you to the correct stock ROM to flash. Flashing the ROM will stop the bootloop.

Fake phones use other parts than the original phone. And since roms are made based on the phone's parts, they won't work on the fake ones.

Thank you very much for your guidance. Yes I can enter into the download mode by pressing the mentioned buttons. It says the following :
Odin mode
Product name : GT-i9505
Current binary : custom
System status : official
Knox kernel lock : 0*0
Knox warranty void : 0*1
CSVCONFIG-LSV : o*30
Write protection : enabled
Emmc burst mode : enabled
Dues this mean my phone is original ? Thanks again for your guidance

I would say it looks valid.
Try to plug it to USB with Odin running on computer and get it detected.
Check samfirmware for i9505 official ROM and flash it.

As mentioned in PM, the phone is real. Now tell us what carrier you're using and we can direct you to the correct ROM for your phone.

thanks again for your help . looks like my mobile is genuine after all .i've checked sammobile as mentioned above but the thing is i am from pakistan . and there is no official firmware for pakistan . can you still help me ?. which rom should i flash ?

Any one you wish. Your phone is unlocked, so you're not limited to a specific ROM. I recommend using one of the ROMs not tied to a carrier, such as ones with the CSC code of BTU.

Samsung is actually a Korean company. So, if your phone is made in Korea, it's probably genuine.

thanks Again for your help . sorry i lost you there "the CSC code of BTU" . after googling i think you are saying that a rom of uk maybe ? if that's the case can i go ahead and flash a uk version of rom ?
and again which carrier should i choose ? i have found a rom but i can't post url so i am going to pm you

*laughs at myself for losing you*
Yeah, that's what I meant. The BTU ROM is an unbranded ROM for the UK I9505. It's carrier agnostic, meaning no carrier mods of any kind and will function in any country, so long as the phone isn't tied to its carrier. Your phone isn't tied to a carrier, so the ROM is fine.

Help please

I bought a second hand note 4 which came from abroad... dont know where but the device shows Sprint . The device shows SM N910F in 'about device'. How ever entering recovery the device info shown is SM N910P. I wanted to check for updates but doesnt work. Later i found the IMEI no. is fake ( shows a galaxy tab in imei info). Kies doesnt connect. 'dm- verity verification failed' in recovery mode. The phone is working properly but want to install complete stock. Have downloaded UK based firmware 6.1. via odin but doesnt install. 'About device' shows ' N910FVPU4COG5' (with FVPU) , the nearest i could find on sammobile is N910PVPU4COG5 ( PVPU which shows CDMA)
Please help me get into complete stock with proper IMEI. I dont even know where to start.

I'd recommend getting a refund if you can as there is a high probablity the device you've purchased has been stolen.

Thank you so much for your response. But refund now is not an option now, as I bought second hand from a friend who came from abroad. I need to find a way to repair it myself. Any ideas?

If you take off the battery, the label underneath should have the original IMEI? Is that there? Then you could put that back using the engineering menu.
See if you have the original label under battery.

the label also has fake imei. its the same number that appears in the device.

I checked few sites. What I think is someone is masking SM N910P with SM N910F ( read somewhere F is better than P and is easier to sell). I think my device has gone through same. I tried installing SM N910F original stock but the device didnt accept. I have downloaded SM N910P also but too scared to try as I have come to know that SM N910P is a CDMA. Any suggestions?

There are apps in the Play Store that do imei changing. Read those app descriptions and do some research. DO NOT PAY ANYONE YET TO DO ANYTHING. I am also looking, so i can get back to you what i find. So for it looks that imei changing can be done easily for free. But you just need to know a proper imei - this is the hard part.
Do you think you can peel of the label to see if another is under there? That may have the true imei.....

Looking at your previous posts it looks like you definitrly have a CDMA device, and from Sprint. This is being faked as n910f, which is an international version BUT GSM. The other possibility is described below...
In Verizon note 4, which is CDMA, there are two sim slots. This is required now by law. One is CDMA and other slot is GSM or actually meant for sim when abroad I think Sprint also is the same. I have Vefizon. Verizon phones are also facgory unlocked. If you are using GSM maybe try switching sim slots. In this case yiur phone has been flashed with international version firmware so it can be recognised on gsm networks. If you have a GSM sim try both sim slots.
EDIT: I checked this and I think Slrint does not have two sims.
Go to this site and post the problem. You will def grt an answer

You are not alone, I got that kind of device too, with same build number as yours. My goal is to put a sprint custom rom and I use miui, but as soon as I install twrp the device got bootloop, I back-up the rom and install miui, now it works perfect, even 99000 imei (maybe the original imei) appears.

Gents, have you tried this - Phone INFO ★Samsung★ from gplay? It's telling what you have in your hands. After that you can check IMEI changing and other things.

Since the imei is all zeros, you've already lost the imei.
Can you return the phone to the seller or ask the seller for the phone imei? You may have to take the phone to a repair shop to have them reprogram the imei.

You just need to program the IMEI. I don't think the serial # will matter.
Can you send the phone back to the seller?

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!

try smart switch on PC to update it... frend of mine had s7 flat and no update via mobile phone, as soon as I connected it to pc and turned on smart switch update came out...

I wanted to mention that, but I've probably forgot. I did try Smart Switch, but it also said, latest update already installed. Any other ideas?

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.
