Hello Everybody,
I would like to begin by saying how much I've learned in xda-devs in the last few days just by searching around the forum and Fixing different things here and there.
This is such a great community that I decided to register
OK so heres the deal:
Last week i bought a Note-2 (N7100) running Samsung Android 4.1.2 (Israel Version) + Rooted
I wanted to upgrade to 4.3 but 4.3 isn't yet released in Israel according to sammobile.com and other people I asked.
I found a Stock Deodexed Pre-Rooted ROM here on the forums (I think version was MK4), Flashed it, and lost cellular abilities (there is signal but emergency calls only) and WiFi.
Flashed WiFi FIX by Dr. Ketan, and by installing Devil's kernel (Patched_N7100_MK4_KERNEL.zip) and GT-N7100_ModemMJ9.zip I was able to gain 3G Functionality back.
Phone was working great for a few days, but then I decided to upgrade to Dito Note v3.2 because i wanted Note-3 Functionality.
After flashing it, I lost the ability to register to network again, started receiving "UIds on the system are inconsistent " and phone crashed every few minutes, screen stoped working every now and then.
I immediately looked for a different ROM to flash, (couldn't find the original ROM I flashed but i found DrKetan_Custom_ROM_V6_1).
So i wipe the phone, cache, sd-card and everything besides formatting the internal storage, Installed this ROM but still had the same issues with ULDS on the system, phone crashes and display shuts down while phone is still working).
Desperate, I downloaded Stock firmware (With KNOX) and flashed it to my device (I used Odin 3.09 and flashed everything, BL,CP,AP,CSC that was included within the original ROM). this was the Seri-Lanka firmware if I remember right.
This time phone boots without complaining about system files, but got "Emergency calls only" (IMEI and S/N still ok!).
In addition, I now have bootloader with KNOX.
I then thought, maybe the modem version is incompatible with the Cellular frequencies in my country (Israel Freqs: 850,2100), so i looked for countries with similar freq and downloaded official firmware for Thailand.
Flashed it with ODIN (same as before, BL,CP,AP,CSC basically everything) device boots fine, WiFi was working, but couldn't register on network ("emergency calls only") even if you can see your provider while manual scanning, registers successfuly apparently,but still no service.
Fraustrated, I rooted the device (Knox turned 0x1 but it doesn't really matter to me cause no warranty anyway), installed Philiz and flashed the 2 Fixes I mentioned at the begining (Devils kernel + Mj9 modem).
This resolved "Emergency calls only" issue, but now i cannot open WiFi at all!.
I tried to flash WiFi fix that i found in this forums but it didn't work. I've given everything I have in the last 2 days trying to fix this issue but I cant seem to solve this problem.
Now I'm just thankful that I can start/receive phone calls with my device.
I can't seem to understand, how did I not have signal with stock ROM?
could it be EFS was corrupted somehow so that only MJ9 Modem + Devil's Kernel read it?
How can i FIX WiFi?
Included screen-shots of "About Phone" and "*#1234#"
Thanks ahead,

Just flashed this with Odin 3.09 but it didn't solve Wi-Fi Issues. isn't this fix for devices without the original Bootloader?

try to flash stock firmware with stock kernel with kies. here you find a guide and let me know if it solved the problem

OK Thanks very much for all of your help.
Does it matter what version of 4.3 I choose to flash via Kies?
In Israel only version 4.1.2 is available and I know that going back from 4.3 most likely will erase my IMEI / S/N.
If i choose a stock rom from SamMobile does it matter what country it comes from?
I don't really understand why are there different modems to different countries, aren't all versions alike?

i have the same problem, and like you, i tried all fixes, but, with nothing solution. I've been thinking that there is no solution, just sell the bad phone and buy a new one, and then no more experience with :crying:

I don't belive in this approach, I know for sure that there is a way.
after re-flashing with Kies and getting "Emergency Calls" again, i tried to flash only the modem, and i saw that i lost connection with cellular but Wi-Fi was still working. only after flashing Devil's kernel it seems that Wi-Fi stops working..
I just got home and i'm not expecting any calls until tomorrow, I will look around maybe an alternative kernel will solve our problems..

Maybe we just need the correct kernel and modem, the problem is that no one's development. Another solution would be to discover how to downgrade from 4.3 to 4.1. For now, our only option is to wait for more solutions and development

OK, so as I promised yesterday, I had the time to dig in to this subject yesterday and I managed to find a solution to get both, WiFi and Cellular working (together!)
Here are the steps i took:
1) Installed Stock ROM 4.3 with MK4 as the main and BL version (this will install Knox but i already had it) and modem version MJ9 (Odin 3.09)
2) Root the device with CF-Auto-Root-t03g-t03gxx-gtn7100
3) Install custom Recovery (I used philz_touch_6.07.9-n7100.tar.md5)
4) Very important! After device boots it automatically attempts to perform update with samsung! DO NOT LET IT as it will install updated modem version. it is important that we have MK4 Kernel and MJ9 Modem for this to work.
5) Flash via recovery the following files:
a) Patched_N7100_MK4_KERNEL - This installs a patched Kernel only this time because we didn't let phone update version after boot, it will be compatible with Phones version.
b) GT-N7100_ModemMJ9 - This patches the MJ9 Modem.
After performing all the above steps I finally managed to get Cellular connectivity and WiFi together. Hope it works for other people as well.
I still don't understand why Stock Kernel with Stock MJ9 modem won't work, what do those patches contain that allows me to get connectivity to cellular network?
This device is not black-list and IMEI is still original and S/N but for some reason won't work with stock.
Seems to me like some of the ROMs maybe modify EFS so that only patched Kernel and MJ9 Modem will work and it's not backwards compatible.
Can anyone confirm this? and if so, is there a way to convert the "modified" EFS version to stock compatible version? or is the EFS file encrypted with propriety Samsung encryption?
You can download the referred files here

Hi, as you can see modem version for you is ending with MJ4 so it's not the same as my version.
Look for a version that has modem version ending with MJ9 and then apply the patch (because patch is for MJ9 modem, and not any other modem from my understanding)
Hope you get your device working!!
More explanation
Here are the steps i took:
1) Installed Stock ROM 4.3 with MK4 as the main and BL version (this will install Knox but i already had it) and modem version MJ9 (Odin 3.09)

Hi there, and thanks a lot for your effort, I am really confused about step number 4, I haven't detected any update from Samsung's side, can you please provide more explanation?
Thanks
Hey All,
I have problems with my GT-N7100 after updating to rom 4.3, it's a weird situation after trying all solutions available online (all solutions I found ).
I will tell you the full scenario and please try to help me with it.
I was on rom 4.1.2 , after flashing rom 4.3 from sammobile, I started getting not registered on network, I couldn't solve it at first and I was afraid to try solving it by myself. I sent to service center and he said he can't make it work on 4.3 and it must be downgraded to 4.1.1 and he did it and it was working. I guess he installed a German rom , baseband: N7100XXALIH.
I decided to try upgrading again to rom 4.3 but first I took a backup by rom manager and then I flashed the 4.3 rom and the network problem happened again, the IMEI is correct.
I tried several ways including ariza patch and flashing several modems but it didn't work, until I found the way to flash: Patched_N7100_MK4_KERNEL then flash: Patched_N7100_XXUEMJ5_Modem.
That fixed the network problem and it worked super fine but at the same time I had problem with the wifi , it can't be turned on.
I tried Dr.Ketan wifi patch, but it didn't fix it.
I restored the 4.1.1 backup which I had at first but I still have the not registered on network problem.
I wanna run 4.3 rom and solve the network problem as well as the wifi problem.
please help me to solve this problem.
PS: I bought this phone last year from HK and I flashed 4.1.2 rom for Egypt right after I bought it and it was working fine. now after I tried rom 4.3 for Egypt, UAE, and HK I'm still having problems.
There is a service office said he can solve it but it's gonna cost around 40 USD, I wanna save that money and know the solution by myself to be able to solve it if I face it later.
Sorry for the long thread. your quick help is highly appreciated.
Thanks
For IMEI do a EFS backup. For Wifi, flash mj5 bootloader.
Hit thanks if i helped you.

Make sure USB Debugging is enabled.
well , I successfully fixed the problem, but now i have a question, I installed my rom from sammobile, did wipe data,cache , dalvik. but still my device status is custom. how to make it official ?!
i seem to be having problems maintaining service in areas i know i should have it. i was on insane kit kat previously, i used to have to put in airplane mode or hot reboot just to get service again. everytime i would turn screen off it would drop service again. i even flashed the nb4 modem...so i switched to gpe 4.4.4 had great service..now again...in areas i had 4g i have nothing...not sure what to do at this point..tried both touchwiz and aosp roms...tried nb4...frustrated...anyone have any clue as to what else i am doing wrong? i alwasys enable roaming...always change network if needed to the most options...at a loss....

i didnt start on 4.4.4...never had the official update to kit kat. only jelly bean. rooted then...been on custom roms since...never flashed anything except the nb4 modem while was on insane kk because i thought that might solve problem...
So you did the update to 4.3? Get phone info from playstore and under firmware info it will tell you what bootloader you are currently on.
bootloader

m919uvuamdl is my bootloader...ummm its also identical to the baseband version...not sure if that means anything...
Check your baseband version in settings, more, about device see if it matches up. To my understanding, you had flashed the NB4 modem correct? It might have failed

it matches up...m919....so this means i have to re odin flash the nb4? does the basband change on every rom you flash?
Yes Odin the NB4 modem, and no it does not change when you flash ROMs.. It probably just failed to flash, make sure you flash it twice
no go...

flashed it twice with odin...i was told to open modem.bin file with the phone button in odin...although if its updating the bootloader...wouldnt i use the boot loader button? but no way was gonna test without checking...so only did with phone button..
Its not updating the bootloader, its updating the modem
Having the same exact issue - cell signal was working to make calls when I got the phone and for a while on an older SOKP rom.
Flashed a newer version and now signal is weaker, data/text works, but making a call fails saying "out of service area" and cell signal completely drops out for 10-15sec before returning for data/text.
I've flashed FROM MDL modem to MK2 and NB4 both and no improvement.
Flashed back to the older SOKP version, no fix.
Flashed other AOSP/GPE roms, no fix.
Flashed Wicked v10, no fix.
Flashed back to stock, no fix.
Flashed back MDL modem, no fix.
Checked IMEI, not stolen or blacklisted.
This is an SGH-M919 S4, but is unlocked (otherwise would not be getting ANY data/text signal either).
My next step is to make sure AT&T has the correct IMEI in their system and see if that helps at all.
But I'm really at my wits' end as to why it all of a sudden flaked out for phone calls.
[UPDATE] Went to AT&T and updated my IMEI number in their system. Signal strength has improved enough and I'm not able to make calls.
good morning! can someone really help me? i have upgraded the firmware of my Gt-N7100 from 4.1 to 4.4 but after flasing, my mobile cannot register on the network anymore. Then i tried downgrading, from 4.4 to 4.3 but its still cannot I connect to the network. Just now i tried to upgrade it again to 4.4 but still doesnt work. it has signal on but everytime i call it says not registered on the network. It also has signal even i remove my battery. I am really bothered. does my phone broken already? i am from the Philippines and the firmware i have now is N7100XXUFNG4_N7100OLBFHG1_SMA, all the firmware i used came here from sammobile. can someone please help me...

How did you flash the firmware? Using ODIN or recovery?
Do you have a nandroid backup? If yes, restore that backup & see where you go.

To keep things short, I flashed stock Touchwiz 4.4.2 via Odin on my Note 2(Wind mobile) because my mom likes the Samsung gimmicky features but I have a problem. I have no cellphone service. I flashed this T889VVLUDNH2_T889VYVLDNH2_T889VVLUDNH2_HOME.tar. The phone says my IMEI is null and the servicemode is blank. I hope someone can help me.
If it helps, I was running lollipop 5.1.1 roms before I wiped everything to flash touchwiz via odin.
