Q Wifi broken on latest bootloader - Galaxy Note II Q&A, Help & Troubleshooting

Hi,
I have been reading the forums for over 24 hours and have gone from a phone which i have spent 4 months sending back to Samsung because it could not join a mobile network, them sending it back the phone stating it was blacklisted, long story short it is not and the phone is clean.
They are unbelievably useless at fixing their own product i gave up and came here.
I found DN3 custom rom, patched kernel and modem.
The problem is i can only get either mobile network working on MK4 Kernel and MJ5 modem or wifi working on MK9 kernel and MJ9 modem.
I have tried the wifi fix by dr ketan however this seems to only work on MJ5 bootloader i cannot downgrade to since i am MJ9 (came like this from Samsung)?
Please let me know if there is anything i have missed, i have read and looked for anything i can find, so hopefully this shows i am not lazy!
Thanks,
Matt

[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?

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
is good to know that you resolved your problem! Only one question, this is the rom of my country, will serve me? Or that rom should I use? The specifications are from sammobile.com

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

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

Sim Card Removed Error

I have had annoying ongoing problem of my phone needing to restart due to my Sim card being removed. I have not removed my sim card at all and it has been happening since I have updated to the newest modem NB4. My setup is as follows the Insane Kit Kat Rom V5 with the included Kernel. To note this has happened since updating to the new NB4 modem. If anyone has any suggestions I would appreciate it.
Nope, so far nothing fixes it other than exchanging your phone and hoping the replacement is fine. There is a thread over on the AT&T forum where people, me included, are having this problem. I've replaced the SIM card, SIM card holder, returned to an earlier nandroid when I did not have this problem. I've also unsynced the play store thinking it had something to do with it since it would always occur when I had an app update waiting for me. So far nothing has fixed it.

I started getting this same message a while back when on Wicked v10 and mk2 baseband. It wasn't the ROM's fault because I was using the ROM for a few months without problems. I updated to NB4 baseband and the same thing was happening. Flashed a 4.4.2 Rom didn't help. it hasn't happened since I flashed Insane kk v5.

Really?? That's great, hopefully it stays working great. What kernel are you using?
I was having the same problem and I did 2 things:
1) I verified I had no foreign debris or anything in the sim card slot. Took a can of compressed air and blew it out.
2) I re'Odin'ed the modem again (twice as mentioned in @shiamatsu thread)
It seems to have fixed things for me. Good luck.

I will try all of these suggestions that I have seen so far. What about Odining back to stock and then rooting again? Like I have stated previously I have started seeing this issue since updating to the NB4 Modem and Insane KK. I am sure it isn't the ROM, so I will stick with Insane KK because it is a nice ROM. If anything changes I will report back.
Well, I'm going to take back what I said about fixing it. Sim card removed error happened again. I managed to get a logcat, and dmesg. I have not seen any smoking guns in the logs so I'm going to try a different kernel.
Let me know what kernel you use.

I had Talexop's and switched to Ktoonsez's (TW 4.4.2). I did get another error after switching so I'm not sold on a kernel issue either.
I think I'm going to retrace my steps and start from the ground up. I jumped directly from the MDL modem directly to NB4. Maybe I need to go MDL>MK2>NB4?? Maybe try a different Odin version? Switch USB ports on my desktop? Different cable? I'm going to keep trying different things until I get it fixed. It is quite an annoyance because the error happens at times when the phone is asleep and you obviously cannot get any calls, messages, etc.
I'll keep the thread updated for sure.
Been half a day and no errors yet (knock on wood). I did not change anything as far as kernel, rom, or modem is concerned. I did go into Settings>More networks>Mobile Networks>Network Operators>Search Networks and then tapped the tmo network (manual network selection).
I do live / work in an area where Tmo goes bye-bye and there is only Vzn and ATT. I recall having to switch networks recently in order to make a call in that area for work from the no signal zone (I have a spare "work" SIM and my phone is unlocked). Perhaps doing that jacked with my selected default network and could indirectly be the cause of the no sim errors?
And I've done the SIM switch in the past on 4.3 roms without issue. Maybe it is a KK / NB4 bug?
Sounds like you're on track bro, I have tried a few things and so far knock on wood like you said it seems to have worked. First I thought about going back to stock but Odin couldn't recognize the md5 or tar files I downloaded. So then I decided to reflash the NB4 modem. I flashed it three times!! Maybe to see if that would make a difference. Then I reinstalled Insane Kit Kat V5 and did a clean install then restored my backup. So far I have Been running my set up for almost 24 hours and not one error! I will keep looking out for it and report back after my current battery had drained out.
SENT FROM MY INSANELY SICK S4
So I just wanted to give an update on my situation. I have gone back to stock the original 4.2.2, and then rooted my device and then installed Insane KK V5. I have noticed with the stock tar ball file of 4.2.2 I get the NB4 modem. A couple times I did not get the NB4 modem I had the original modem. So then I flashed the NB4 modem and my phone was saying unknown baseband. The last two times I have went back to stock it has given me the NB4 modem and I am still on Knox free bootloader. I am still getting SIM card removed errors, more frequently than ever now. A few times my phone tells me that there is no SIM card inserted at all!!! Very frustrating, I was on a phone call earlier tonight and the error happened during the call. So I called Tmo for a replacement SIM card and we will see if that helps, I'm optimistic that it will. I'm now convinced it may be the NB4 modem, we will see what happens when I get my new SIM. If anyone has any more suggestions I will be open to them.
SENT FROM MY INSANELY SICK S4
I had one error since I last posted. I agree that it must be something with the modem and perhaps we are the only 2 people seeing this issue (I find it hard to believe). I am also on the 4.2.2 bootloader with the NB4 modem. I'm hesitant to downgrade as it has not happened more than once over 4 days.
Let me know if the new SIM cures your problems. I may have to make a trip to the local tmo store as well.

Well...Here is my latest and greatest attempt. I flashed the NB4 modem 3 times (no auto reboot throughout the process), and did battery pulls after the first two flashes. 36 hours and no messages.
Sorry if this is a noob question but I'm having this same issue and waiting on new sim tray, which I gather....isn't going to fix the issue. Did you flash this modem in recovery or through Odin? And I'm not too keen on this Knox business. Im on a 4.4.2 ROM and not sure what bootloader I'm on and not really sure how to go about finding out. From what I gather, the process is different...... Or the file nb4 file I need to flash is different for each bootloader. I'm glued to this thread because I just bought the phone on CL about 2 months ago. Im pretty upset about this to say the least. I loved this phone before all this bull****

I'll try to explain what I know (which ain't much!). In order to avoid Knox some folks including myself have retained the knox free (MDL) 4.2.2 bootloader. How to tell if you have a knox free bootloader look HERE (credit to @shiamatsu) By flashing a modem.bin (which can only be done via. ODIN) we are able to have the benefits of the newer radio, but keep the knox free bootloader. A few of us like _eroz and crazyc78 have seen issues with SIM errors since going to the NB4 modem with MDL bootloader. And thus this thread. And in case you want the instructions to upgrade to the NB4 modem look HERE
I imagine if you don't mind knox and you did the full upgrade, you probably should not be seeing the SIM card errors. I'd be curious to know if anyone is seeing SIM card removed errors with the NB4 bootloader / modem.
Brain hurts. Time for a beer...
Thank you. I'm gunna give it a go and see if it works
This may be a hardware issue. My wife gets it on stock never rooted.
I am curious to know when you flashed the NB4 modem did you go back to stock first and then reroot your device and then flash a rom and then odin the NB4 modem? I did all that and still got errors. I am going to update to Insane Kit Kat V6 later tonight hopefully I don't have issues after updating. I am going to try your remedy and see if it works, and if it doesn'tjust wait for my new simcard.

What's the deal with lte radio?

hey guys I'm on 4.2.2 still. Rooted it and deleted the galaxy walking app, so haven't been able to do legit update, and with working alot just haven't fooled with it. Anyway I'm off and have time, want to come up to kitkat, am I not able to update my LTE radio? I'm reading and searching before turning to asking, but all I'm seeing is if I update it my sound will act up. Am I stuck on an old radio now? Was hoping for improved signal, can I go stock, update and reroot and everything will be current?? Anyway any help is appreciated.
If you don't care about tripping Knox counter, just flash the NB4 firmware with Odin and you'll be good.. I recommend fenny's fixed firmware
Edit: well it will only trip if you flash custom recovery or kernel, other than that there is root method without tripping if you plan to stay stock

im not staying stock, just want the updated lte radio on it. thinking of going lg g3 since sammy become such a pain in the ass. I've flashed stock and am updating official kitkat now, i guess that will update my modem and lte radio also, i'll reroot after that and throw something on there
If you are updating officially there shouldn't be a reason to manually update anything
i was just trying to save time, my home internet is crappy ( 100.00 bucks a month for 5mb, more like 1-3 mb) and you have to use wireless to update. I'm on kit now, abut to root and find a rom

There is a thread in general specifically for updating radios for those of us still on MDL. If you were to have followed that guide you would have updated your radio without any sound problems, would still be KNOX free, and would still be able to have the option to run 4.2.2, 4.3, and 4.4.x ROMs flawlessly.

i've been searching here for years on everything. Unless you stay in the loop everything is just cluttered. Even rooting, I'm looking and reading threads from pre 4.4.2 where chainfire link was last updated in 2013, it sucks searching here. And I thank you guys for the help. I'm rooted now and didnt want to ota, but everything I found to read said I could update the modem but not the LTE radio without sound issues... I must of missed something. LOL, I had a ton of tabs open from searches before posting. Been rooting since iden on nextels in early 2000's so it's just basic info I need thats hard to find here , tons of threads I guess. Anyway lets a get rom on this thing..

I totally agree and understand. I've pretty much been tinkering around the S4 forums since a few weeks after release (before I even purchased my S4) and have followed pretty well everything from square one so it's pretty easy to remember THAT I've read something but not remember WHERE I read it... Looking back through the Q&A and General threads, I couldn't imagine just now getting into the S4.

I would be interested in that thread... I have updated my GSM modem (modem.bin) to NB4 but as I understood it, the LTE part is tied to the bootloader. So, those of us with MDL have to retain the MDL LTE radio. If it is possible to update the LTE radio, without the sound/wifi problems, and retain MDL bootloader and thus no Knox, I'd love a link!

Ahh, you got me on that one. It didn't even register to me that the LTE modem is unaffected by that method. My apologies.

Bad/no reception on T999L, need help/suggestions

These issues started with the upgrade to latest T-Mobile 4.3 software pack at the end of November. Phone operated perfectly before then. After the update, the phone would periodically not receive/place calls/texts/use data. The issue kept worsening daily. It is not related to the SIM card or location, as the card has been replaced and tested in an alternate phone where it performs perfectly.
The T999L was then consequently rooted, KNOX flagged (it's already past warranty, Samsung wouldn't give a rat's ass about it), flashed to CM11 M12 and later a variety of modems was tried. Same issues persisted. Restored to stock 4.1.2, same issues. Did 3 updates OTA to get to latest 4.3, same issues.
Messed around with 4636 menu, 2263 menu, etc. Some changes had a temporary result but nothing permanent. Calls to the phone are redirected to voicemail. When placing a call, it takes 5-10 seconds to either place it or disconnect it (as it can't connect to the network, I guess?). The bars on the phone show 3-4 bars typically, but the phone is rarely able to acquire a data connection. Again, this is not the case with other phones the SIM is tried on.
Any suggestions? I've spent probably close to 10 hours researching this and trying everything out and I am absolutely stumped. This is my mom's phone and a replacement Alcatel OneTouch Fierce 2 just "doesn't look nice", so I'm getting a fair bit of *****ing for trying to help solve this, even though it's not my fault. Would appreciate some help before Christmas.
Have you tried updating the modem?

I'd say so. Used this thread: http://forum.xda-developers.com/showthread.php?t=1880987 and flashed the 4.3 basebands for T999L and T999N, total of 3. I'm thinking this is something to do with the 4.3 bootloader or basebands... any methods to go back to 4.1.2 without a brick?

If you have a T999L stick to the designated T999L modems and nothing else, or you may damage the device. If you have a 4.3 bootloader there is no way back. Have you tried to use ODIN to flash the latest NF4 firmware for your T999L and then do a factory reset using the stock recovery? I posted NF4's link in this post. Good luck.

Downloading right now, and will test. Pretty sure this is the firmware update after which this problem started occurring.
Any other ideas for what might be affecting this besides baseband? I have a feeling something else might be causing this. I'm not familiar with Samsung partitions though and what is flashed by OTA/Odin.

Well, OTA updates can sometimes fail, that's why I gave you the ODIN firmware link. It's the best help I can offer.

Lost signal on NH7

Hi everyone, I recently bought a cheap S4 M919 with the NH7 basband and keeps losing signal whenever I stress the phone like downloading or tethering. So I search all forum and tried to flash the NB4 and so on without luck and I starting to think that it´s a hardware issue but the technics that I know are suggesting another antenna or a bridge in the network filter (their words not mine) but I post here as a last resource. Someone has the latest basebands NK2, OH3 or OK3 alone? Please
I upload my settings because I wonder if it´s a tinkering issue
Does everything work properly on a stock ROM? If it does, the problem would be software-related.
