[Q] N7100 No Wifi after "Emergency Calls" FIX and WiFi Fix (STOCK 4.3)

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)
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.
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

Definitely more info needed.
What ROM is on your device?
What bootloader did you install?
What modem/baseband/radio is on your device?
What method did you use to try to install the bootloader?
Is your phone still showing the correct IMEI in settings or 0 ? (Compare between that shown in settings and under the battery.)
It may be as simple as updating your modem, but I/we can't tell yet.

I'm new at this, in fact I have flashed by old Captivate several times but yet to flash my SGS3. Anyhow, I have spent many hours reading. Before doing anything I suggest, read, and read some more.
Don't flash back to 4.1.1 or 4.1.2 at this point. They will install an older bootloader than is currently on your phone. From what I have read, you narrowly escaped bricking your phone. You might want to read some of the threads regarding the 4.3 stock ROM and unbricking before making any changes in restoring your device.
You can probably fix this by flashing the modem that goes with the 4.3 series ROMs. It would also be the MJB flavor, although the MJ2 would probably work. Several of the 4.3 TouchWiz ROMs in the development forum have download links for the MJB modem. I would guess you were probably going to install one of them. I would recommend flashing the modem to see if that solves your issues before going ahead with the ROM flash.

The reason I didn't put a link in the previous posts was to get you to read about what you were doing as you searched for the modem. I am offering advice on things I have yet to experience on this device and only speaking second hand. My advice is only based on what I have read not on anything I have had to correct myself.
In truth I think you just stopped too soon in the process of what you were doing earlier. You said you installed the 4.3 bootloader in preparation to installing a 4.3 or later ROM that required the up to date bootloader. You didn't mention installing the current modem/baseband. You didn't mention trying to flash whatever ROM you had been considering.
You may be able to correct your device simply by installing the 4.3 modem. HERE is the modem thread, it is in the General Forum for our device. Make sure you pick the correct one. I don't know if your device will work well on the MJB bootloader and modem with a 4.1.1 ROM, from something I seem to recall reading I suspect it will.
Take this in steps. Install the correct modem, the one that matches your bootloader. See if that corrects you sim, data, and IMEI problems. If it does correct the issues, the next step is to decide if you want to stay on the 4.1.1 ROM or change to whatever ROM you had been considering. If you decide to change, make backups first. If it doesn't fix the problem while on 4.1.1 you may want to flash the version of the official 4.3 ROM enewman17 has provided on the development thread.
Take it one step at a time. Read about what you are about to do until you understand it well, all before doing anything. Make backups sequentially as you make each corrective step.
HTH.

thanks man for telling me what was wrong your an amazing human being and i love you (no homo) and thanks again a million thanks bro.

Did that modem fix some of the problems?

If your on 4.1.1 shouldn't you flash the DKL3 version or can't you just flash thru Odin the DLK3 stock ROM thru Odin Amd start all over again
I've been on 4.3 with that bootloader Amd have flashed back to 4.1 back to the baseband version DLK3 firmware. I would think being on 4.1 you should be able to reflash using Odin to fix the issue or flash the modem for 4.1 .

[Q] Not registering on Network / Wrong IMEI after flashing stock 4.3

Hi, I have just flashed Rooted Note 2 on 4.3 to the latest stock ROM which I downloaded from the SamMobile and now it will not register on the network.
The new version I flashed was the same as the old as i found it with the CSC N7100BTUEMK2 on sam mobile.
I checked the IMEI and it says 00499010640000 in status menu which is different from the one under the battery.
I did not perform a backup of anything as I was not worried about losing any data.
Any ideas what has happened to it and how to get the IMEI correct again?
I understand this is something to do with an efs file but in what way it has become faulty from flashing the same rom I cannot decipher
Any help much appreciated! :good:

From my experience:
1) Reflash the ROM.
2) Flash a custom ROM.
Both worked for me.
N7105 rocking AOSB with AGNi kernel,
Click "Thanks" if I was of any help!

Thanks, I have reflashed the current 4.3 rom UEMK9 and a slightly older UEMK4 with a DEMJ9 radio.
I have tried lots of radios - DM3, XXDME4, XXMI6, XXMJ5, XXMJ2, and some other modem.bin
From what I understand its when you go from newer to older roms that you get IMEI problems, so its prob useless to try pre 4.3
Its all a bit confusing to me and which rom has which radio seems like an arcane mystery.
It is quite possible that I flashed a same version 4.3 rom but my old radio was different and not knowing it was such a minefield on Galaxy phones I never checked that or bothered with a back up.
I may have to resort to paying the people at unlocksamsung online £26 to reset my IMEI
Can anyone tell me, is it just the radio that causes the IMEI problem and should I just trawl through flashing radio zips until my IMEI comes back so I can save the efs file?
BTY everything else seems ok SN is correct and wifi works fine, I just can't get on a network without my correct IMEI
Thx

i also have the same issue on my note 2 gt-n7100 and now phone does no respond to the touch post rooting and all..i am tired of rooting and unrooting the phone like 100 times allready and now my phone is stuck in loop

Questions About SIM Unlock

Hello.
I have the SGH-M919 with the following details:
Android version: 4.2.2
Baseband version: M919UVUEMK2
Kernel version: 3.4.0
Build number: M919UVUAMDB
This is after using various guides to rooting, getting rid of the SIM lock, changing the baseband version and reverting it.
Right now the phone works, I can make calls and the sound is fine. However, I can't turn Wi-Fi on. Thus, I have a few questions:
Is there a way to fix Wi-Fi on my phone?
Will upgrading to 4.3 be worth it, or will there be any risks?
Will upgrading/flashing a new (stock) rom bring back the SIM lock, or am I done with that?
Thanks.

1) there are several ways. You can start by downgrading your modem to its original since you are still on older firmware and see if that works
2) not very risky, just make sure you know about Knox and all that
3) Nope, unlocked for good

Thanks!
I'm so happy to know that it's gone for good. That means I could probably just flash a stock 4.3 rom and get the matching modem with it, and hopefully have wi-fi working, right?

[Q] SGH-M919 Modem/BootLoader Question

Hey Everyone,
I'm currently running a Knox (Warranty VOID) bootloader, and M919UVUFNB4 Modem Firmware/Baseband on a Rooted T-Mobile SGH-M919 Galaxy S4, Running 5.0.1. Sometimes I get Emergency Calls Only/Insert Sim, and the only thing fixing this is a reboot.
I'm looking to update the Modem to Fix the Issue.
I Need a recommendation as to which Modem/Bootloader or Both do I need, that you know for a fact works.
What do I load 1st BootLoader or Modem and How to do both?
Sorry for Noob Question. Just don't want to screw things up.
Thanks.

Keep in mind that the SGH-M919 (Android 4.4.4 - M919UVUFNB4) has a restricted bootloader.
Can anyone else provide the steps on flashing the bootloader that would allow the OP to either upgrade ONLY the bootloader to Android 4.4.4 (M919UVUFNH7) or downgrade to Android 4.2.2 (M919UVUAMDL)?
I am particularly interested in how one would flash the bootloader to an older version; specifically, Android 4.2.2. (M919UVUAMDL).
