[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] smelenchuk:
I've done some poking around in the modem images for LALH1 and VLLH1, and I've reached the conclusion that they are, for all intents and purposes, identical. The only difference is that VLLH1 is padded at the end with a large amount of empty space (LALH1 even refers to itself as VLLH1 internally).

Just thought this would be useful to anyone wondering about that.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
I'm leaving them both up so people that are looking for a very specific version for whatever reason can find it, but thanks for the tips!

That's only because it's recently added - I'll update them all with build dates now. :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Ian1331:
I have been having trouble connecting to wifi (obtaining IP) for several days across several roms and I have been flashing the older H1 and K4 Canadian modems with no change. This morning I decided to try the "newer" H1 and after a reboot my wifi has been completely restored. I just read that the H1's are identical.. But for whatever reason, it made a big difference for me.

Edit: just rebooted for the second time since flashing the new H1 and I completely lost wifi, can't obtain an IP. Looks like I spoke too soon :(
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
Modem files don't control WiFi or Bluetooth. You might want to try doing a full wipe (wipe System, Data, Cache, Dalvik) and installing a ROM that is known to work well, like the CM10 "final" build.

You could also try connecting to a different WiFi AP; There might be some strange settings on yours causing this problem.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Ian1331:
I've wiped everything (including internal storage) several times over the last few days trying to resolve this. I have found a work around though. If I change my router to broadcast b/g/n instead of just N, wireless is rock solid after reboots. It's important to note that is is only an issue with 4.2 roms as freshly installed 4.1 roms like my wireless N only mode. Their seems to be similar findings to this with early 4.1 builds but only a couple lonely people on 4.2.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] double RL:
As soon as I upgraded to the 12-23 AOKP 4.2.1 from Task, mine got stuck at "obtaining IP". I redownloaded the rom, wiped everything, and tried any and everything possible with nothing helping. Finally figured out that if I forget the network, put it in airplane mode and then reboot, it would finally connect. Weird, but works. No idea what the issue is.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bobloadmire:
How come everyone says these modems control wifi and bt in addition to cellular then? i believe these modems are an all in one chipset, they should affect all I/O.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] kofrad:
I believe the way it works is that the cellular modem relies on a closed-source firmware blob provided by the carrier or manufacturer. This is why we have the radio/modem files to flash. Other connectivity (wifi, bluetooth) is built into the linux kernel and doesn't require the proprietary firmware.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bobloadmire:
Right but firmware is below drivers in the stack.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
Right, but the WiFi/Bluetooth/GPS is handled by a different chip from the cell Radio. Here's a great test: Write from /dev/null on to the modem firmware and see if WiFi still works. (Warning, device might not boot after.)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] smelenchuk:
If anyone's brave enough to actually try this, I'd be interested in hearing if the phone boots afterwards. (I suspect it will, but I'm not risking my connectivity to test it out myself.)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] kofrad:
I've got an old Inspire I'm tempted to try this on but am not sure if I want to try it. At least not without a decent shot at fixing it if it doesn't boot.

Any idea if fastboot/bootloader would still work if the modem has been flashed /dev/null?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bobloadmire:
Lol I really don't want to do that but I was told it was all built into the same chip. I can't remember where I read that, so grain of salt.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
I really suggest that you don't do it, because the bootloader fails to initialize if the modem firmware is missing. I've pretty much done the same thing, and it's not easy to fix. I was just trying to get the point across.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] marinierb:
Aren't these radios supposed to be named in alphabetical order? If so, then this order is incorrect:

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] meleii:
I'm not sure how it would work if your using 747m on at&t. I have no personal experience with using a phone on a different carrier.

The only thing I could say is to make sure you have a backup and try. If it don't work restore.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] slackercow:
i went ahead and gave it a shot... tried H1 modem first, booted, no signal, couldn't add/change any APN. tried to flash back to original modem, wouldn't boot past SGS3 logo. i restored to a back-up and got it booting, but still no signal. using ODIN now to get back to stock and maybe start over. don't think i have enough energy to care/do this again until tonight.

Hi I have i747m (rogers version, canadian) that I have unlocked.

Currently, I am using it with straight talk service (at&t//t-mobile)

However, I get really ****ty 4g service and I feel like maybe this is because of the modem that is currently in place (i guess it would be rogers modem)

Would it get better network service if I change the modem? should I just flash modem from here? would it work?

Quick question.

I just rooted my girlfriends s3 its the att version, after flashed jellybam and was ready to inputy info but there was no data. My question is this, do I flash after flashing Rom or can I include it while using twrp to flash the Rom modems. Ultimately though when will it behest to flash the modem?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] marinierb:
Flash modem at any time. It makes no difference at all. It's a completely separate piece of firmware that goes into it's own memory space.

Use the one that gives you the best results, not need to redo.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bigal1542:
So the best one won't change on an upgrade? Like if I'm on an older one now that works best, is it possible that a different one is now better on 4.2.1
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] corythug:
Probably not, they are more your personal area related then android version number related.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
Not 100% true. New modem versions will likely be released for 4.1 and 4.2 that support features that weren't available in 4.0. Using older modem firmware on a newer ROM should never give you problems (OTAs update the ROM but sometimes leave the old modem) but you might be missing out on some new feature that might, for example, lower battery consumption by falling back to 3G when you're not using the data line.

There are many other variables in modem firmware though, and "modem features" aren't likely to change much, so I would still agree with corythug.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bigal1542:
Thanks guys. Cleared that up.

Now a question based off those: are the newer modems generally better around the US? I'm going to be traveling a lot and am looking for the best one in general. I'm running AOKP 4.2.1 if it helps.

Thanks guys!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] smelenchuk:
What modem is best seems to depend a lot on the device and the general network conditions of the area. You'd be best off trying them for yourself and seeing which works best for you.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
^ This, plus:

If you switch from one major version to another (4.1 -> 4.2, etc) you might find it worth your while to try each modem again; It might take some time, but like I said before, you might end up with much better results than expected!

Worst-case scenario, you end up back on the modem that worked best for you in the first place.

This is strange...I have a I747U and I flashed from I747UCLH9 to I747UCDLK3 and I saw my 4G speeds plummet to like 30-50 kilobits per second. I flashed back to I747UCLH9 and I'm still getting really terrible speeds. I tried a few different AOKP ROMs from task650 along with different modem combinations and I still have really the same awful 4G speeds.

WiFi's doing fine as usual though. I checked my data usage and I've only used 700 megabytes out of 3GB; I don't even tether.

My mobile network type is LTE:13 and my signal strength is...2147483647 dBm and 255 asu? What?

I read somewhere that I might have to get a new SIM card from AT&T?

Anyone here on Telus compare LH1 versus LK4? Which one do you find is better?

I've been trying both and LTE connection is intermittent with either one. Can't really tell if one is better than the other...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] kl25:
i did a search but couldnt find the answer i was looking for.

i'm currently using a rom (jedi invasion) that is based on the tmobile stock rom. i am using a i747M that's with Rogers, a canadian provider. i checked the APN settings and everything seems to be correct but the phone now only shows that i am getting 4G connection. (i do have LTE in my area).

does this mean that i need flash the i747M modem in order to fix the problme? if so, will this create more problems since i am using a rom that's based on the tmobile rom, im thinking there might be compatibility issues if i flash to the canadian modem.

thanks for any help.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
No LTE available in my area, so I can't help with that one. I've been using LH1 on MIUI for months and get great stationary H+ reception, and solid H while moving, if that helps. I also visited Edmonton and got amazing LTE speeds on the same modem.

747

M

means that you must install Canadian modem updates. Any other modems will cause you to lose all connectivity. Make sure you've got the Rogers LTE APN information; A TMobile-based ROM probably has the "standard" APN XML for carriers across the globe in it, but not the latest LTE information for non-relevant carriers. (T-Mobile won't care if their Rogers data is out of date.)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] kl25:
thank you for your help.

Is there a way i can check whether or not my current rom has the correct modem for my phone? or i'm guessing it doesn't since it's a tmobile based rom right? just wanted to double check.

in "about phone" my baseband shows as i747mvdlk4 (if that means anything regarding my modem) and i just discovered something. under "status", the mobile network type shows as "LTE:14" but the icon at the top shows "4g" but not "LTE".

and with regards to the APN setting, i selected the option that's named "rogerslte" under the APN settings menu.

thanks.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
If "Network Type" says LTE, you're already on an LTE connection.

ROMs don't include modems. You can flash any ROM you want, your modem won't change.

Baseband = Modem

"rogerslte" is just a name, the settings inside could be wrong.

LTE

is

4G. HSPA (the previous generation of connectivity) is a 3G connection, but the carriers all started calling it a 4G connection (essentially, lying) back when WiMax was coming out because it gets almost the same speeds as WiMax (WiMax is also a 4G connection, but it's garbage and nobody uses it anymore)

The "G" stands for "generation"; It's like saying the PS3 and Xbox 360 are both "7G" game consoles. It doesn't mean a damn thing.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Urinophoria:
Out of curiosity, what kind of speeds are you getting? At&t uses the terms lte and 4g interchangeably, even down to the labeling on the stock ROM. Most custom ROMs however, don't. I'd be more inclined to go by network type than by the icon. LTE:14 is LTE regardless of how the graphics are displayed in the ROM.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] kl25:
thanks for the help! you guys are right. did a speed test i was getting about 26 mbps download speed.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] loonieryan:
Well, based on my testing for the past few days around the western parts of Montreal the LK4 modem seems to be better and locks on to an LTE connection more reliably than the LH1 modem. I'm going to stick with LK4 for now and continue monitoring performance.
