hi guys. my question is should my baseband be MDL for a MDL rom? I never did the tmo software update to MDL but rooted and started flashing right out of the box. For the most part I've had pretty good luck flashing roms but I see most roms are MDL which Im still on the original MDB baseband even after flashing several MDL roms. My baseband stays the same. Off topic I noticed my system settings about phone does not show what modem I'm on. I'm confused if I were to flash (haven't looked into in yet) a new modem. How would I know which modem I'm on? I feel like I should be on a MDL baseband but am skeptical about the difficulties regarding root. Anyways is it possible to flash a new baseband like I would a modem or kernel? Or should I just odin a MDL stock rom with root injected? Then start from there? I had trouble getting root and a recovery on my friends phone that had the update so I used odin to go back to MDB because that was the easiest solution for me at the time. Silly question but is the modem and baseband related in any way? I guess what I'm asking is what do you guys recommend? Are you still on MDB like me? Or is MDL a must?

If you started flashing custom stuff back when MDB was the latest update; and you haven't manually updated your baseband... then no, you should still be on the previous baseband. Also, your modem should be what your baseband is.. MDB. I know that if you flash ROMs in CWM/TWRP you aren't getting the modem/baseband. If you just want to flash a new baseband/modem, check this thread out. I will say though, unless you are experiencing problems with the MDB modems, there's no real reason to go changing it.
Hi Guys. I got my T-Mobile Galaxy S4 in May of last year. I promptly (as soon as I got home) rooted it. It is on Baseband M919UVUAMDB and I am currently running a December 9 nightly of CM11 (4.4.1) because any newer versions cause an issue with sleep and Wifi. If my phone goes into deep sleep with WIFI on, my screen will completely freeze, requiring a battery pull.
Now I've tried multiple roms running TW based on 4.3 (Guessing they're based on the M919UVUEMK2 OTA), but they all drop data.
Now that M919UVUFNB4 is out, I was wondering what would happen if I flashed to that (waiting for a pre-rooted ROM)?
Will I have the same issues? I love CM, but TW is full of features I like to use and would like to swap back and forth if possible.
What are my options? I no longer have any backups of any stock roms (I do have a 4.2 TW ROM backed up that had NO issues. I believe it was deodexed as well, if that has to do with anything).

The data drops are because you have the MDB modem. If you want to run those 4.3 based ROMs, you need either the hybrid MK2 modem (reversible, knox-free) or the full MK2 modem (not currently reversible, installs knox). The same situation would exist with the MDL modem.
See this thread for instructions to install the hybrid modem: http://forum.xda-developers.com/showthread.php?t=2546024
I don't know, but I'd guess the situation will be similar with the new KitKat release. To run the new ROMs properly, you'll probably need the newest modem (either a hybrid or full). I'm fairly confident that you'll run into the same issues if you're on MDB, but again, this portion is speculation. MK2 might end up being sufficient, or NB4 might be required. I won't be surprised if a hybrid MDL/NB4 modem pops up soon.

Just to be sure, I can run this via ODIN, since it's not MK2, it's MD, right?

I think so, but I'm not 100% sure. It looks like the same deal as the hybrid I've been using, and that I linked in my first response in this thread, just with the NB4 GSM modem and the MDL bootloader instead of the MK2 modem and MDL bootloader.
I never want to be among the first to flash new radios though. I hold off until I see a LOT of success stories and a lot of devs recommending them.

Yeah, it's also the reason I never flash OTAs, and am on such an ancient baseband. Thanks again!
Here lately when I get home, cannot force phone to connect to Airvana at all, unless I flash back to TW based rom, then update prl, then flash back to open sourced ROM. Anyone else have this issue? I am on nd8 modem, only thing I haven't tried is flashing previous modem.

problem seems fixed with mk3 radio flash from ND8.

For anyone else who comes across this thread, do NOT downgrade your modem from ND8 if you are on the ND8 bootloader. The OP must have flashed just the ND8 Modem only for the short time it was available, so this was possible for him but won't be an option for most.
Thank you. That is all.

I have an ATT S3 which had 4.1.1 firmware before I rooted, flashed a ROM, etc. I'm having a GPS issue, but this doesn't seem to be the usual GPS issue S3 users encounter. From my research, I've seen S3 users stating that GPS works for them, they flash a certain ROM, and all of a sudden it doesn't work at all on any ROM (until they either tighten the screws in the phone, or reflash stock firmware in ODIN, or something like that). GPS works fine for me--I get a satellite signal fairly quickly, and the signal is strong enough to be accurate... but only on Jellybean ROMs. If I flash any sort of Kitkat ROM or newer, GPS can never get a signal. However, once I flash back to any ROM that is Android 4.3.1 or below, it starts working fine again.
I'm thinking this is related to the 4.1.1 firmware I had on here before flashing ROMs. I had a very similar issue with radios and getting cellular signal. With the 4.1.1 radios, I was able to get signal just fine on 4.3.1 ROMs and below, but Kitkat or anything above would not be able to find a signal. I flashed a newer radio in TWRP and signal-finding now works fine on all ROMs. [Side note that potentially is related, my i747 is unlocked and I'm using it with a T-Mobile SIM] Would flashing 4.3 stock firmware, which would perhaps give my phone "newer GPS radios" for lack of a better term, fix this issue? I don't want to leave 4.1.1 firmware if I don't have to, since apparently 4.1.1 firmware is more desirable, and once you go to 4.3 you can't come back down.
I think you have summarized it well. I have seen others comment about running newer ROMs on older firmware and modems with issues related to bluetooth, gps, and wifi. Firmware and modem upgrades fixed there problems.
You have already taken care of the greatest reason I have seen regarding having the 4.1.1 firmware, sim/carrier unlocking the device. From all I have read, that unlock is permanent no matter what rom changes and wipes you may do in the future. I guess a jtag or mobo swap would remove the unlock.
The drawbacks with the official 4.3 release (MJB) are Knox and the inability to downgrade. Knox seems to be in the official ROM and not in the firmware. I say this because the custom TW roms, 4.3 or 4.4.2, come without Knox. enewman17 has even removed Knox from some of his stock rom images. The same holds true for the three official Kitkat releases, NE4, NJ1, and NJ2: Knox and no downgrade. There is an extra kicker with the 4.4.2 releases, the modems will brick the phone if their version does not match the firmware version.
There is one thing you could do if you did not want to commit to MJB. Prior to MJB being released there was a leaked 4.3 stock rom with firmware and modem. Several custom TW roms were developed from it and you can still get the firmware and modem files in some of the threads. The short code for that release was MJ2. The great thing about the firmware with this release is that you can still downgrade it. You can also run the MJ2 firmware, (firmware = bootloader in the way I use the terms) with the MJB modem (modem = baseband = radio). The MJ2/MJB combination is downgradeable. This bootloader/modem combination file can be found in the OP of some of the ROM threads by loserskater and others. Even better, there are several custom TouchWiz based KitKat ROMs that will run on this MJ2/MJB combination, as long as you use one of two custom kernels; one is by ibuddler and the other is by ktoonsez. Ktoonsez has his own thread, just be certain to grab the correct kernel. He has downloads for TW and CM/AOSP kernels for several android versions. Links to ibuddler's kernel can be found in the Likewise ROM thread, IIRC. I know these kernels worked with NE4 TW ROMS and the MJ2/MJB combo. I haven't seen mention of if they will work with NJ1 or NJ2 based ROMS.
It could be that Ktoonsez' CM/AOSP 4.3 kernels will provide the same functionality with current CM/AOSP roms. At one point CM/AOSP roms based on Kitkat stopped working with the 4.3 bootloader, it was either November of 2014 or 2013. I have never seen mention of LP or MM roms working with the 4.3 bootloader, regardless of the kernel.
A reason to consider running a newer ROM is the Stagefright fixes to be found in them, incomplete as that may be. I haven't seen the fixes mentioned as incorporated into any of the TW based ROMs other than enewman's stock image. CM11 does have the fixes but seems to require a 4.4.2 bootloader and modem.
Something else that can be used to fix gps problems is an app called GPS Test. After an update or flash, many people have encountered gps issues, and often all you have to do is open the app and let it find all the satellites it can. Then open maps and it should get a quick location fix. (You may or may not have to clear data on maps or other gps related apps first). You can Uninstall the app afterwards as it only needs to be done once.
This doesn't always work, but it has enough to be a worthwhile alternative to try before flashing.
Also, I've noticed on more recent builds, gps/maps just can't seem to get a location fix. If you're in a bind, just leave it running for a bit and sometimes it'll start working after a while. Again, this isn't always the case, but it's worth knowing/trying if you find yourself lost or in a bind and cant do any real work/troubleshooting.

Thanks for the help from both of you! I tried the GPS fix app and unfortunately it didn't work. I'll give MJ2 firmware a go.
Just to confirm before I flash...MJ2 provides all MJB 4.3 radios and such, while retaining the ability to downgrade to 4.1.1 if I wish? I just want to be 100% sure before I flash this.

Yes, I did this myself. No bad side effects observed.

Well, actually, I used the flashable zip that contained the MJ2 bootloader and the MJB modem. I downgraded both back to 4.1.1 to do the free unlock. I downgraded, confirmed downgrade, performed the unlock, and then went back up to MJ2 bootloader and MJB modem. I have since upgraded to NE4 for bootloader and modem.

I'm confused once again, and I know I shouldn't be...
I did the free unlock in 4.1.1, so will going to this MJ2 un-do the unlock with the new radio?

Sorry about creating confusion.
Your Unlock, free or otherwise, is permanent - or so I have read. Going to MJ2 or any of the newer bootloader and modems should not change your unlock status.
I meant that I was already on MG2 (4.1.2) before learning of the free unlock. From MG2 I was able to downgrade to 4.1.1, do the unlock and then upgrade to the MJ2 bootloader and MJB modem. Months after that I again downgraded to 4.1.1 with no issues. I upgraded that same day to MJB and then to NE4 in order to install CM11.

I found a page on galaxys3root.com with links to 3 files... Stock 4.3 MJ2 with root (and I think no KNOX as well), MJ2 modem, and Insecure 4.3 kernel. Since these are all separate files I have to reboot to recovery and flash each one individually. I'm assuming this is what I'm looking for. If it isn't, then feel free to chime in and tell me to stop, since the downloads are probably going to take a very long time to complete (on my Windows XP netbook from 2011).

I recall seeing that page before I first rooted my S3, but I didn't use it.
Since you have TWRP you could flash the MJ2/MJ2 bootloader and modem or the MJ2/MJB bootloader and modem and not lose the ability to downgrade. There are download links in several ROM thread OPs, the ROMs I recall offhand in S3RX by loserskater and TMS3 (don't recall the dev). You could root by flashing the SuperSu.zip from TWRP. The link is in the OP of the stable thread.
I think this is what I did: custom recovery and then SuperSu.zip while still on stock. Later I went to the TMS3 4.3 rom while on MJ2/MJB. I regained root with the same method after the downgrade and subsequent upgrades I mentioned above.
Problem solved. Can now acquire GPS signal through Waze on 4.4.4 Quantum 5 ROM. I appreciate the help.

I have been happily running AICP Lollipop since July 2015 on the MK3 radio. At the time, I read about issues with the "newer" modems and not being able to roll back the firmware to an older modem. I'm interested in trying out the newer Android 6.0 roms, but many of them mention a requirement of the ND8 modem. I haven't had any major reception issues with my current MK3 modem. Are there any issues upgrading the device to one of the newer modem?
I found the L710VPUDNJ2_L710SPRDNJ2_SPR stock file on the forums here. From what I gather, this would upgrade my device to stock along with the more recent NJ2 modem? Do I just wipe my current system (I already have a nandroid backup), and flash this image with Odin? Even with a backup, I have a feeling that I won't be able to go back to my old rom. Should i just go to the older ND8 instead of NJ2 since that is the minimum required for many of the 6.0 ROMs?
Nj2 works fine. That's what I have now. No issues updating. You flash the nj2 .tar in odin. Then you will be able to restore your aicp nandroid.
To root, of course, just odin flash the latest twrp .tar. The newest is twrp 3.0.0-0.
You nandroid should work fine, but I would take this chance to do a clean flash of the rom.
I think 12/27 is the latest aicp lp. They have aicp m now. It works pretty good.
I was running the newest aicp marshmallow for a few, Not quite as smooth as LP. I went back to lollipop for now.
