[Q] am i really on MDL even if i says MDB?

so even if im on a MDB baseband and ive flashed MDL roms but my baseband still says MDB afterwards.. it updated me to MDL? Because ive noticed that after flashing serval MDL roms my baseband does not change. That sounds kinda fishy to me that it wouldnt say MDL. i was thinking that i needed to flash to MDL to insure it will work properly with MDL roms. i was about to odin a MDL root injected rom once i found one to fix this issue but now im skeptical since i think im aready on MDL. Your modem is your baseband? Can i just flash a MDL modem and it will show MDL afterwards not MDB in the about phone. How come it doesn't change when i flash a MDL rom. i rooted and flashed on the a stock MDB baseband and its read the same a dozen roms later. i also rolled back in odin my friends OTA updated MDL to MDB so i could use moto chopper to get root. it rolled back fine. I was able to get root with moto chopper but it still read MDL even afterwards. I was pretty sure it was on MBD even though it didnt say so.

Thanks for the link, but even after flashing the MDL modem in odin it still shows that im on UVUAMDB. is that right? shouldnt it show that im on UVUAMDL now? is it only a s4 problem? i heard on a youtube video that the baseband reads the same but DID update. i've flashed dozens of modems on my s1, s2 and s3 and i knew the modem changed because it say what modem im on. i just want to make sure im using the best modem for my area. i am having an issue with death star 4.0. i use to get a strong lte signal at my home now i barley get 4g and it goes on and off mostly off. lte does work if i drive down the street but most of the time i dont have internet connection at all then it pops up for a couple of minutes at like 4 bars then back to no connection figured it might have been a problem with the modem. other roms i used i havent had any issues with data yet. just test driving this rom because a buddy of mine wants it. i personally prefer aosp roms.

I did the same as you; got the phone with MDB and wasn't on the stock ROM for more than a day or so. It took a few flashes for my baseband to report as MDL once that was out.

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.

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.

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.

This was the 2nd post in the thread. I've tried all that and for a while I thought it was fixed. I think I made it 4 days without a problem but then they came back.

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.

[Q] Where is this 4.4.2 modem people keep referring to?

I flashed the Root66 KitKat update for Wind Mobile using Odin. As I was looking through the settings I noticed there were no APNs set. I googled for Wind's APN configuration and manually entered them (before I even tested data, perhaps it was working regardless).
So far I've seen a number of mentions warning against flashing the 4.4.2 modem before flashing the 4.4.2 firmware update. However, I've yet to see the modem posted anywhere. The most recent one in the baseband thread was for 4.3. What am I missing?

Normally 4.3 modem will be working for 4.4 too but you should not have older modem then 4.3

It hasn't been posted for that same reason, so nobody will attempt to flash.. Anyone can make a flashable zip for the modem, that it why we are letting people know what happens when you try to flash on older firmware
Sent from my SGH-M919 using Tapatalk

Ill still post the modems in the near future, but wanted to first get that warning out so as many people as possible already know about it when I do. Flashing the 4 4.2 modem on 4.3 firmware has bricked quite a few devices in the Spirit and AT&T forums already. And despite all our efforts, we have yet to get the debrick method to work
That said, if you have a need for the modem, ill get it for you as soon as I can.
And just fyi, after updating to 4.4.2, you cannot use any older modems. They won't brick the device, but you won't have a working radio/signal.

Heya Doc
I have a Gs3 T999v from Videotron and have been running the 4.3 modem since early this year. I'm currently running CM11 4.4.4.
I was wondering if it would be possible to provide a link for their 4.4.2 modem so I can give it a shot. I know I won't be able to come back from it, but reception with the 4.3 has not been that hot and I've been meaning to get those kinks out. Also since the phone is nearing the end of it's life, at least to me, I don't mind the extra risk. Even if it should technically be entirely safe to do so since i'm running 4.4.2+
Cheers!

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.

bandwidth connectivity issue, (installing new radio possible fix)

i just encountered this issue the last few days and continues even after installing a new rom. im having trouble downloading files online or apps from the play store, its almost like the connection keeps getting disconnected and reconnected. im also having a problem playing a small online game called spades that worked fine a few days ago. its a card game so is not graphic intensive or take up alot of bandwidth.
another issue that ive just dealt with for months is rarely getting LTE data even though i should be getting according to the coverage map. im usually in wifi so it doesnt bother me too much but it got me thinking maybe i should look into installing another radio/modem which could possibly fix these issues. my current baseband is UCUFNJ2

You're running the latest modem for this phone, so there's nothing newer available. People have hard bricked the i747 on newer firmwares getting the bootloader and modem unmatched, so you have to be careful. We used to think the bootloader couldn't be downgraded at all post Knox, but it turns out you can downgrade as long as you don't go back a major version. There's a set of odin flashable files available. That's the only confirmed safe way I know to downgrade NJ2. Since you're already on NJ2, you have to stick with a 4.4.2 modem.
Safest thing to do, if you want to try out a different modem and just give the phone a fresh start would be odin back to stock NE4 4.4.2 using the files you can get from here.
From there you can test drive NE4 and see if it works any better. If you leave it stock it should offer to OTA to NJ1 and then back to NJ2 too, letting you fairly safely try out all the modems left available to you.
