N9005 won't pick up 3G networks

Hi guys,
My actual phone info:
Bought with JB Stock Vodafone from Spain
Imei unlocked
Updated over OTA to kitkat
rooted via CF auto root.
Knox tripped
Phone info:
XXUENA6
XXUENA2
VFGENA4
For a week, I looked all over XDA forums, read all threads but I still can't find a solution for my n9005 problem.
Here it is: I bought one in Spain, imei unlocked it to use it Morocco. Everything worked just fine and I could use gsm network with a sim from IAM (Moroccan Provider). I then set up mobile APN to have 3G, made sure my sim is 3g enabled, but the phone refused to pick up the 3g signal. I checked the phone's mobile network settings, and found that I haf only 2 options: gsm/wcdma automatic, and wcdma only options.
Well, since Maroc Telecom(IAM) isn't offering a 4G coverage yet, I think that's normal not to have the 4g option. Still, When I use the automatic option I only get 2g signal (and can read my mails over gprs,get twitter notifications, but no internet via browser, etc..).
When I choose Wcdma only option, I simply have no network signal at all.
When searching manually for networks, I get all 3 moroccan's providers but only their 2g networks.
I was prompted for the kitkat update via OTA, updated but it didn't solve the unavailable 3g problem(and caused a few others I managed to solve).
Now, I rooted my n9005 using cf auto root, and off course tripped knox, tried to reset the phone many times, but still no way to have a 3g signal.
Thought about installing a compatible Rom, but I am a newbie, coming from the Apple world, and need some help with this.
Actually, it amuses me that I really waited until android started to ressemble to IOS to decide to switch once for all to Android
Please guys, if you have any idea to help me get the 3G signal, that would be awsome.
Thank you in advance.

[Q] Note 3 N9005 Not registered on the network! This is weird! Please help :)

Dear All,
Trust this finds you well
I have this very unusual problem. I have a Galaxy Note 3 N9005 and I live in Denmark. I havent have any problem with the network what so ever. 4 Days ago, I suddenly realized that I cant make any calls and I get "Not registered on the network". Although I can not make/receive calls, the data seems to be working (3g). I tried other sim cards on the phone and they work perfectly. My sim card also works with any other phone!! I did everything I could find on forums (from flashing new roms to....). I went to Telia store ( Telia is the company I get the network), they tried to reset my number and my sim card, tried new sim cards... but it just doesnt work!! They told me that they havent seen anything like this before. Looks like my phone is blocked on Telia Network!! No Telia sim cards works on my phone but others do!
I have tried new modems, firmwares and etc. The phone is unlocked. Right now I have flashed X-note but its still the same. No matter what Rom (custom or stock) I use, it just doesnt work. Can anyone please help me?? Much appreciated!

Hello, i got exactly the same problem here, i was thinking that the problem was about region lock but in fact it's not.
I tried everything like you, flashing modem, stock rom, custom rom... everything i found on the web and nothing worked for me.... I bought the SM-n9005 1 month ago in france, and now i live in new caledonia, i was able to make call for about 2 weeks without any problem and suddenly, impossible to connect the network. Samsung gived me the region unlock code but didn't make my network work again.
I'm so disapointed. My imei and baseband are correct.
bootlader : N9005XXUGNG1
baseband : N9005XXUGNG1
PDA : N9005DXUGNH1
CRC : N9005ITVGNG1 (audax rom)
Please someone help us !

Hello @yashironc
The interesting thing is that my phone is also from France! I have been using the phone for 6 months and no problem at all! The problem suddenly appeared few days ago. I'm actually considering to change my network provider as it appears to be working on any other one! Hope it will not be the same after some time...

please someone help us

Tried This
one thing can tried is changing the imei number, to a phone thats not connected to a telias network that way it will registered on the network another new phone it looks like your phone got blocked by your carrier

Try this.. It worked for me for my note 2...
Hi I faced the same kind of issue with my note 2 and I found some solution.
1. Download the previous version of firmware from sammobile. ( Eg: If the current version is 4.4.2 you have to download 4.3).
2. Flash the firmware using Odin.
3. After flashing the firmware now update the firmware to current one using Samsung kies.
4. After the updation when the phone reboots your issue may get resolved.
It worked for me. Just try doing that......

Thanks Rafi. I tried this but it didnt work out because when I connect to Kies, it says that I'm using the latest firmware which is strange! Looks like in Denmark, the updates are a bit late. I will try to change my IMEI number, hope it works...

Yes, may be your phone has been blacked list by Telia network. Ask your Telia network to be sure?
But curiously, how can you change the IMEI?

same problem here after afligt

Hi, i don't know if changing Imei will fix the problem because my carrier don't blacklist phone and I have the same problem here :/ I got now a phone who can't make call. Damn Samsung 700 € for that ?

Thanks vndnguyen for your reply. I asked them several times but seems like they havent blocked my phone!! They were in shock like me I finally decided to change my network provider as it was the cheapest and easiest solution. I think if the IMEI number is blocked, I should not be able to receive signal from other providers as well, cause that doesnt make sense in terms of security. Hopefully someone could find the answer to this unusual problem and save some lives Cheers!

Nope, if your imei was blocked, you still can receive signal from your home network, but you can not make a calls.

There is a difference between the two IMEI blacklists.
One is Provider-based. Meaning your provider can block your IMEI on their network alone. Other providers work without issue. They used to do this here for a long time if you used a different device than the phone you purchased from them. It still happens in some countries if the device is from another country or sometimes when it runs a customROM.
Providers are also very good at denying this.
The other is the international blacklist. This one renders a phone completely useless worldwide, and is usually reserved for stolen devices.

Note 4 exynos sm-n910k Problem please help

So I am from Canada and picked up the exynos version from a Korean seller on ebay.
Model number sm-n910K I actually have a huge problem. When wifi is turned on phone will reboot whilst in sleep mode after about 5 minutes if I turn off wifi it works fine. Note this happens even if I am not connected to a network the radio just has to be enabled. I am out of options I might rma it to the Korean seller but I think I might have to open a case with ebay, as these guys are being very difficult here is a video attached. I filmed it for 5 minutes but only recorded the last minute. http://youtu.be/ahLB0A2pCOM any help would be super appreciated thanks guys. I am at a loss whether this is software ie corrupt modem from improper driver installation at factory or just a faulty modem things I have tried already.
1. factory reset + cash wipe
2. Reinstall firmware using kies
3. turned off automatic scanning
4. turned off download booster.
The only thing that works is keeping wifi off. Any suggestions would be appreciated thanks.

Have you tried flashing with Odin?

Hey, I also have the SM N910K. What network are you using it on?

I have that version as well without that issue. Can you grab a picture of your About device specs?

Hello there i got same version SM-N910K i didn't have that issue with wifi , but i got battery drain , i live in uk and the phone keep searching for LTE- A ,

N910C with the Samsung SoC
I have the same Issue, i live in the US, I was in Malaysia and manage to get a N910C with the Samsung CPU, when I set the network to LTE/WCDM/GSM (autoconnect) it keeps serching for 4g networks, and it does not switch to lower networks even if available, which causes a huge battery drain, i had to set it down WCDM/GSM for it to get data. I did not have this issue with my note 3 which i also got in Malaysia last year, btw, the note 3 came with qualcomm cpu, and that leads me to believe there is a problem with the modem on the samsung SoC.

Hi! i found a solution where you can force your phone to go to GSM Only, WCDMA only or your preferred network type. In your dialer app type: 319712358. It will ask for a password and the password is 774632. And voila you can now choose what type of network you want to use. This will help with the battery drain.

Hi everybody..im from south korea. I have sm-n910k.
do you have any idea for rooting this phone. I cant root this phone because of bootloader is locked. Anybody help me how do i unlock bootloader?

Update to the latest 5.1.1 ROM, and follow the steps on the page. You're good to go.

Hey i was wondering if anyone could help me. I have installed a custom Rom made for N910C on my N910K and then flashed the stock kernel and modem. I was on stock marshmallow rom and the custom rom is marshmallow as well. Everything seems to be working fine except for when i make phone calls i hear weird and loud crick crick sounds and it is impossible to make phone calls. So is there any way to fix this problem??

can you share the 910K stock flashable kernel and modem link?

No phone calls?

Hey guys, I come here very often and now I'm going to have to open this thread because I've seen absolutely no posts about my problem..
My S6 Edge+ is currently unable to make any calls and I don't know why..:crying: the strange part is that I can still send text messages and use my SIM's mobile data... Another weird thing is that whenever I reboot the phone, my WiFi passwords are forgotten..
Can any one help me? I'm currently running android 6.0.1 and I am considering downgrading it to 5.0.1 to see if it solves the issue...

Still needing help..
No one?? I really need some help since I've tried 4 different roms and modems ano nothing seems to work....

Have you wiped everything and then flashed a stock rom?

Which variant do you have and which MM firmware did you flash? Check your modem, imei, network operator etc and provide that info here.
Also wifi password IMO related with
Code:
ro.securestorage.support=true
this line in build.prop. I would suggest you to add this line under 'ADDITIONAL_BUILD_PROPERTIES' in build.prop but assume you havent rooted your device. If have, add it.
Powered by Elektrik

I've downgraded to 5.1.1 and it didn't work, I have the international version of the s6 edge plus and now I'm looking for a new ROM to test to see if I can solve it.. I've checked my imei in two different websites and on imei.info it comes clear, but the other site gives me a blacklisted warning, which makes me think since I bought it online second hand... it probably was reported stolen or lost and now it's blocked... which ise rather inconvenient. .
If I go to SIM Card Status it says "Not Available" everywhere, but on imei information it says my imei and on IMEISV the value is 01. It's network unlocked and right now I'm about to flash a new ROM, probably stock..

Hello, I have the same problem at boot after I receive the call when making a call nothing remains of numbering you have a solution? thank you cordially guillaume

Hi guys, I know this is a really old thread but I'm here just to say that the problem was with the IMEI, it was blacklisted..
I changed it with a friend and then everything worked fine..
Thanks for you help mates!
