I am going to stick with the 4.3 update and bootloader. The issue I currently have is the "Unknown" baseband. I don't currently have a mobile signal and need to restore the baseband/modem. Would this be corrected if I go back to my backup of 4.1.1 and allow the phone to accept the OTA update?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
The bootloader version is not listed in "About Phone". I've already told you, flash a modem. Don't flash "return to stock" packages or older bootloaders. If you do, you'll brick your phone.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DroidJay123:
I have flashed a modem from your posting (i747UCDLK3) via TWRP and did a wipe of dalvik and cache. This is when I started having the "UNKNOWN" under baseband. Same goes for the IMEI/IMEISV. I have attempted to flash one of your modems to fix the problem. I tried to download your most recent modem version and the file is no longer available to download?

Modems and Bootloaders

Greetings,

I am having a bit of an issue that maybe you can help me with. I had to update my bootloader from I747UCDLK3 to I747UCUEMJB in order to get the latest version of my favorite ROM to flash, (Beanstalk 4.4+). When I did this I lost my modem connection. I found your thread and have read through most of it, and in here you state than any modem should work, ,and that depending on your location one may be better than the other. I have seen this in the past so my issue has me bamfussled. My problem is that the only modem I can get to work is the latest one that matches the name of the bootloader version I used, I747UCUEMJB. While this is not a major issue in and of it's self, my download and upload speeds are now really weird. I now only get about 15-17 meg download speeds at the best, instead of the 25-33 meg speeds I was getting with the UCDLK3 modem/basband version, and my upload speeds are now like 17-22 megs instead of the 3-5 megs I had on the old modem version. This is like I went from ADSL to SDSL on a land-line phone based DSL service 7-8 years ago with no throttling. Can you tell me how to get the older modem to work with this new bootloader since I cannot back the bootloader out. I also did see that you said this could happen, but it would resolve it's self after a reboot, but I rebooted three times on the UCDLK3 Modem and it never would give me service.

Thank You for your help,

Gary

I think it was the MDL but please don't quote me on this. It doesn't matter to me anyway since you can't downgrade once you are on a higher modem.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
Yes you can. You can install

any

modem version for your device at any time. There's no risk in doing so (except for random incompatibilities between versions)

You can not downgrade a bootloader. They're very different parts of the phone.

Hello, I have a small question. I want to update my S3 to 4.4, can I update to 4.4 with the mvldlk4 bootloader? Or do I have to go to stock 4.3 rooted with Knox removed and then flash 4.4?

Is it possible to have the 4.3 bootloader and still be on 4.2.2?

I am on 4.2.2 with the modem (i747MVLDLK4)

If your phone has any cellular connection whatsoever, your modem is "working".

I have a similar issue with the version of 4.4 I am running. I'm not familiar with the Beanstalk ROM, but check your settings for connection speeds, some of the ROM'S come with 2G/3G throttling

Hi,

Is there any known information regarding battery life?

Can a different modem firmware increase battery life? Significantly?

Are there some known to be buggy?

I am asking because I suffer from heavy battery drain from the beginning on (4%/h with >90% deep sleep).

Personally, I would attribute this to the modem firmware but of course, I am not sure...

A modem can effect battery to some extent. If you have a modem that's puling a weak signal. You can try out different modems easily. I assume your 4% lose is on stand by? You can also use betterbatterystats if you don't already. Would give you some info on your drain.

Just upgraded to 4.3 stock with root a couple weeks ago and decided to see if there were any better modems. I have tried a few and have been unable to get a data signal with any of them other than the most recent modem. My Wifi and Bluetooth seem to work fine and I believe I can make phone calls, but no data connection and it seems I am not connected to the mobile network and do not have an IP address.

Any ideas?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
The new bootloader that comes with Samsung's 4.3 updates makes older modems incompatible. Just reflash the newest modem for your variant.

Unless we get another new round of modems with 4.4 (assuming we even get 4.4 from Sammy...) I doubt that anyone will be flashing modems on their i747's because of this fact.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] pckarma112:
Wondering about this?

I'm glad I found this thread. I understand what you are saying about the boot loader. But, here is what I am wondering about. I recently bought a used att s3 for my son. To bad it is on 4.3. I own a note 2 that was never upgraded to 4.3...Over on the n2 forum. They are using older modems to get to the dialer unlock trick. As far as I know. This trick worked on the s3 too. I'm wondering if anyone has tried that yet. Anyway I have some more research to do. At some point if I get all the right files together. Gonna give it a go.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
The dialer unlock trick worked on my S3 (a Canadian model) on one of the older modems when I did it about 6 months after the S3 came out. You should be able to use any modem version with any bootloader version without problems (as long as it's for the right model) and probably make the trick work for you too. (Even if you have "no service" while doing it)

I'd try the 2nd or 3rd modem version, the newer ones removed the needed functions.

Once you unlock it, you can flash any other modem and still be unlocked. I've flashed dozens of modems, some not even for my device, and never lost my unlock.

If you are already on the newest bootloader (MJB), none of the older modems will work.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dy/dx:
Thanks. I think I am.

But that's a conundrum. I read thatt you should never ever downgrade the bootloader, right?

What happens if I flash the Samsung stock again? To my understanding the firmware also contains the modem, right?

Does this also mean that I can never revert to stock firmware (e.g., to sell the phone)?

In any case, I upgraded the modem 2 months ago or so and before everything was working (but I think I had a huge battery drain caused by the radio but this did not change with the latest modem). With I747UCUEMJB, 2G works just fine ("E" symbol), 3G sometimes ("H"/"H+" symbol) and 4G/LTE never: When I turn on LTE, the "LTE" connection symbol appears but qickly afterwards disappears. Even worse, once the connection is lost, I need to reboot the phone in order to even get 2G or 3G connection back.

What would you in this scenario?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Najuto9tail:
You can only go back to stock 4.3 mjb bootloader firmware.

If you got at&t sim, in apn settings add the word hipri in apn type. That helps mine somehow... Or either change the Rom, some Roms I ve tried does not get good reception signal and it will lead into having 3g/4g and not lte.

Mjb modem works good for me and my wife but I prefer mg2 because it gets more speed and signal on my phone. Her's have mjb bootloader so I can not change it.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] nodyarg:
Actually, you can flash any firmware you want. The modem justs wont work until you flash a 4.3 modem over top of it. I was trying to unlock my phone by downgrading to 4.1.1 to access the hidden service menu, the firmware downgraded fine, but the modem didnt take and said no service and i had no baseband. I flashed a 4.3 modem over it and it worked fine. I havent run into a rom my phone wont take, except the GS5 rom that has now bricked my phone, but thats a whole different story.

Basically dont try to downgrade your bootloader and you will be fine, you can flash any i747 rom whether its stock or custom, in either recovery or odin, then flash a 4.3 modem over top.
