[Q] 4.3 modem on 4.4 rom - Verizon Samsung Galaxy S III

Is there an issue with using the 4.3 modem on the 4.4 rom? I recently went to TW 4.3 but then went back to 4.4 AOSB and some of my apps don't get data connection and I seem to have terrible service everywhere?
If so where can I find a usable modem?
Thanks in advance

If you are on a 4.4 AOSP ROM then you can update your modem to the latest. ML1. Just update the modem NOT the ML1 firmware

ohhh ok so if I have already upgraded the firmware I should odin back to stock 4.2, then I can load the modem and my 4.4 rom?

No.
#1,There is no stock 4.2.
#2, if you did flash the 4.3 firmware you'd be stuck on stock 4.3. This isn't your case at all since you're on aosp 4.4.
If you're having signal issues you're free to flash mf1 or mb1 aio firmware zips. But you can only flash the 4.3 ml1 modem zip.
Does that make sense?

I've seen the same issue on ASOB with the with ML1 BB and MF1 FW. I put my phone back to MB1 (Android 4.1.2) with Odin and re-rooted it and installed a custom recovery and then loaded the ASOB 1.3.1. I then loaded MF1 FW then ML1 BB. Seems to work fine now.

You must switching modems not firmware. There is HUGE difference. If you are loading the ML1 firmware then you can't go back previous firmwares. Period. But you can go back on the modems.

He did it correctly, mf1 firmware to ml1 baseband (modem).

ya I definitely didn't flash the firmware then because I specifically waited to make sure I didn't get screwed. I guess something in the flashing process went wrong and I'm going to try a new rom to see if that fixes it. If not then I'll just re-odin like lakingslayer did and hopefully my problem will be gone.
Thanks guys!

[Q] If I have VRBMB1 can I flash a rom that is VRBMF1?

Sorry, I'm a total noob. I don't really understand how the "Baseband Version" factors into the ROM/phone operation. Can someone explain it? I have a pretty good understanding of computers but when it comes to the phone it seems very black-boxy -- I'm still learning. My underlying question is:
The BoneStock ROM says: "BoneStock v3.0 (VRBMF1) 6/23/13", my phone currently has VRBMB1. Can I flash the BoneStock ROM on my phone or do I need to upgrade the Baseband Version somehow before I do that? I saw links to different revisions on the BoneStock thread but there isn't a whole lot of explanation about how to use them.
Thanks,
-Greg
Yes No problems. I ran mb1 on bonestock.

Cool, do you know what the Baseband firmware does? Should I flash my firmware to VRBMF1?
I flashed mine mf1 because it really did help signal and data speeds. In my opinion it is worth it to flash the mf1

Did you flash it before flashing BoneStock or does it matter what the order is?
Modem has no relation to what ROM you are on. You can flash whichever you want first, doesn't matter.

Have you gone completely back to stock with Odin? I'm confused if you used a stock rooted rom or cleanRom.
If an odin back to stock doesn't work I'm out of ideas.

Ok, well if it worked then it's not like it's completely busted.
Try to odin completely back to stock: http://forum.xda-developers.com/showthread.php?t=1974114
This will ensure everything is perfectly stock, flash the mb1 image and then ota to mf1 and reroot, then once everything is on the mf1 base, only flash TW roms based on the mf1 base or use AOSP roms.

If it is working then suddenly not in the same day I'm leaning toward hardware issue. Have you tried restoring to stock but not the newest update? Try a older firmware. I had a friend I helped root his s3 and there was a issue with the newest firmware giving this error when flashing custom roms since the roms were based off the older firmware.

Tacking onto what @ems3 posted, you could try this as well which involves Odin and flashing the pit file. Disregard everything after the first post as there was an unnecessary discussion that quickly followed.

I aslo have camera errors today after flashing the Synergy ROM (r484). I'm set on this ROM because it is the only one I've found that will
Support other cell carriers on a Verizon SCH-I535 and I need to switch carriers in a couple of days. Some one in a developer thread said that it should get the older firmware flashed to fix the camera or else I could choose to change the kernal. My firmware is I535VRBMF1 and what was sugested was MB1 firmware. I have several questions. What would I risk or loose by going to the older firmware? How do I get it and flash it (I have Odin but haven't used it yet). The Kernal came with Synergy ROM and is refered to as Ziggy's.

You don't stand to lose anything except possibly data connection and speed, and signal strength and quality. You can find the all in one (AIO) zips from Invisiblek's thread, just flash VRBMB1 aio in recovery. Invisiblek does not make any of these that are Odin flashable for JB and beyond.

I337 ATT MODEMS: OC3 NJ4 NI1 NC1 NB1 FMLD MK2 MJ9 MJ6 MF3 MDL MDB Modems

UPDATED 4-08-2015 with NEW ATT MODEM OC3 5.0.1 Modem
A NOTE TO CLARIFY MODEMS AND FLASHING THEM: Your Modem is your BASEBAND. Flashing a Modem will UPDATE your BASEBAND.
Flashing a Modem and Updating your BASEBAND does NOT change or lock down your bootloader at all/any further than it already is.
The BOOTLOADER is what determines how locked down your phone is and WHICH root/recovery method can be used.
IF you are on MDB or MDL BOOTLOADERS then flashing these modems will NOT effect your ability to flash anything or change your bootloader.
If you are on MF3 or Newer bootloader then you can use SAFESTRAP to have its recovery and flash compatible Roms AND these modems.
If you are on MK2 bootloader you can use MK2's version of Safestrap and flash compatible Roms and Any of these modems.
To VERIFY "WHICH BOOTLOADER" you have on your phone you can follow these basic instructions.
1. Get "Terminal Emulator" from the play store.
2. Open Terminal Emulator and then type "su" without the quotation marks.
3. Hit the "x" and close Terminal Emulator once you have granted it Root Permission
4. Open Terminal Emulator app, type "su" without the quotes
5. Type getprop ro.bootloader
6. Look at the first line that shows up which is the installed bootloader. It should read "something like"
I337UCUAMDB/ I337UCUAMDL/ I337***MK2/ etc. etc.
I have put the other ATT Modems here as well for users to find the ATT specific modems in one place or in case you need/want to go back to your previous modem. Flashable in CWM/TWRP Recoveries.

FOR SAFESTRAP MF3 and NEWER USERS
This is what a tester DeadlySin9 did. He flashed the MJ6 Modem and it worked fine. He then tested going back to the MF3 modem. So if your signal becomes worse you CAN flash back to MF3 Modem but IF you have problems you may need to follow his advice below.You can see his comments here:
DeadlySin9 said:
Baseband is back on MF3 after flashing. Interestingly enough it's booted into stock and safestrap isn't loading. SuperSU is loaded and giving toast notifications and even let me grant to TiBu. Will try reinstalling SS and/or rerooting and see what works.
Back into my Safestrap slot, modem stuck across reboot. Rerooting was necessary, although root wasn't lost (go figure). Data and service are enabled just fine. Will try going back to MJ6 modem

I am putting these ATT I337 16GB and 32GB pit file here as a repository for anyone that may need it in the future. Please use at your OWN RISK and KNOW WHAT your doing and WHEN to use these to save your phones life. PLEASE do your research before using these to flash with Odin. They CAN ruin your device if used wrong or use the wrong one.

I am thinking there is no difference between the 16GB and 32GB pit file as they are exactly the same size and have the same exact md5 even though pulled from different phones.

In my experience modems can be better or worse. It all depends on where your located in the country. What works good for one person may not work good for another. The choice of having more modems to flash can increase or decrease your data speeds/call quality.
It does not hurt to try out modems and find which one works best for you in your particular region.
You can always flash back just as easy with the exact same modem you had if it doesn't work better for you.

Baseband update

Just have a quick question. I'm not really all up to date with how the radios work but the new I535VRUCML1 is abler to be flashed I'm on 1535vrbmf1. If I flash the new radio will I still be able to use 4.1.2 roms or only be able to use 4.3?
It would be wise to stay on the MF1 baseband until you decide you want a 4.3 TW ROM. I Was on an AOSP 4.4 ROM with MF1 and had no problems.

You cannot be on anything older than a 4.3 ROM with the ML1 radio... you WILL brick.
There is a ML1 radio available for download and all you have to do is flash it in recovery. But like I said, you must be on a 4.3-4.4 based ROM to flash it without bricking.

Ok great thank you. So if I try a 4.3 ROM and decide to go back to 4.1 or restore my ROM I should also flash the old mf1.

That's not true, at least not for all phones. I flashed the ML1 radio while running a 4.1.2 Touchwiz ROM and everything worked fine. My signal and data speeds seemed worse than on the MF1 radio though, so I flashed back.

I could be wrong but from what I've read, many people must be extra careful about what radios they flash and when... especially with ML1... for some reason.
Sent from my SCH-I535 using xda app-developers app
Ml1 radio will work fine on any rom you run. If you took the OTA update, then you are unable to flash any radios since you have the entire ML1 firmware. The bootloader needs every part of the firmware in order to boot.
Since the flashable zip is only the radio for ML1, there's no danger of this doing any harm or bricking your phone. People have reported much better signal strength when using the ML1 radio with the MF1 firmware on 4.3 roms. I would stay on MF1 if using a 4.1.2 rom. I'm actually still using MB1.

You're mostly right, if you flash the entire ML1 firmware you will brick, and that will cause problems when you run a 4.1.2 rom. Flashing the modem only has no bad effects except for possibly decreased signal strength.

Do you think ML1 would be any better for me than MR1 on an AOSP 4.4 ROM?

It's possible, but you aren't going to do any harm testing it out.

VRUCML1 should work a little better on AOSP than VRBMF1 so long as it includes commits like this

What rom/modem has the best reception now?

I'm running SlimRom 1.9 (AOSP 4.3 not KitKat) with the MF1 modem. I live in an area with somewhat poor reception, so data speeds are very low in my apartment. But recently I've been getting too many dropped calls, nearly every call has problems.
What are my best options at this point?
1. update to ML1 modem (not firmware) and keep using AOSP
2. switch to 4.3 TW rom and ML1
Any other things to try?

You won't.
As long as you flash the ml1 modem you'll have no issues at all. Just don't flash anything that says ml1 firmware or ml1 ota stock rom.
