i cant install any other rom with Odin. just this.
service mode just stick on first page.
any idea to help please?

none
i cant help ,wait for ohther peolpe

* restore your efs backup
* It's very weird that you can not install other firmware. Remember that you can not do MG9 downgrade modem. Try install Kitkat with pitfile.

I used to root my Samsung S3 phone with different types of custom roms but most of them drained out my S3 bsttery fast. Due to this experience, I'm scared to root my Samsung S4 which is still in it's original rom and already updated to 4.4.2. When I looked at your screen shots, I kept wondering why your android OS was so high. I was thinking perhaps it was due to your phone being rooted? Is it because most custom roms drain battery faster than original roms? My S4's battery lasts much longer than my S3. I can put aside my phone with the wifi on and battery at 100% when I sleep. When I wake up, the battery is around 98%.

i have same problem anyone can help me plz
thanks in advance

any idea please

Hi mate,
The problem in the case above is that the phone lost its IMEI , if your case is the same and you do not have a efs backup , you will have to go to a service shop to have it fix , they need a tool like z3x or similar to fix it

thank u,
my IMEI is fine its repaired IMEI "cause here in turkey somehow we have to do that" but as written above i get no network after return it to 4.2.2
any idea?
thanks in advance

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.

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??

[Q] No signal

Hi all,
First of all, I have a Samsung galaxy s4 from Canada specifically from Rogers. I have got it hardware unlocked, rooted and I am on Cyanogenmod 11.
Now to my problem, I am in the Philippines and I would frequently lose signal, if I'm lucky, it would re-aquire the signal but most of the time, my work around is to turn airplane mode on and off and it would connect back to the carrier for maybe a minute and fully lose signal again.
Any help or suggestions would really be appreciated as it is such a pain to airplane mode and off when I'm jamming to my BT speaker
Here's information about my phone:
Model: sgh-1337m
Cyanogenmod version: 11-20150309-nightly-jflte
Android version: 4.4.4
Baseband version : 1337mvluamdj
If i could help you guys, help me with my problem just let me know.
Thanks all for reading.

Signal issues are mostly connected to the modem,
Flash the right modem for your phone/carrier and see if it help

Hey, thanks for the reply!
I'm a little new to this, could you go in depth on how to do so. Or maybe direct me to a few links I could follow? I am not in Canada and this is my only phone, so I don't want a chance to brick it.
Thanks!
Edit: do I need a computer to reflash the modem because that is something I don't have at the moment.

Here is a modem list. It also has a guide on how to flash.
There was another thread that included the latest lollipop modems , but I can't find it anymore.
You will need Odin which means that you require a PC.
Go to sammobile.com and check what version you need for your carrier and country

Try this method by flashing newer modem and bootloader via Odin
