Hi guys,

I'm new here in xda-developers, and I'm also a newbie in the android rooting world.

I have an unlocked Galaxy SIII AT&T (I747) which was running very slow, so I decided to give it some more life and do a factory reset, root the phone and install a custom rom. I decided to go with Cyanogenmod, so I installed CM 12.1 (using CWM custom recovery, by the way). I have flashed both the latest snapshot and a couple of nightly builds, and they all seem to work fine, except for the fact that none of them detected the SIM card, so googling I found out that I needed to update the modem (and I found the list at the beginning of this thread). I have flashed all the modems listed in this thread (plus another one I found elsewhere). The ones that "work" best are I747UCUEMJB and I747UCUEMJ2 (which I found elsewhere). However, none of them detect my mobile data. Looking at the configuration options, there's no APN configured, and when I press network operators (settings->mobile networks->network operators), it doesn't detect anything.

I also found out some recommendations about deleting telephony.db or clearing the data. Using CM's terminal emulator, I ran the following commands:

rm -fr /data/data/com.android.providers.telephony/

rm -fr /data/data/com.android.phone/

Which I found on this forum:

android.stackexchange.com/questions/129886/com-android-phone-has-stopped-after-dirty-flashing-cm13 (I removed the "http" because the forum doesn't allow me to post outside link because I'm a new user; I'm putting it here as a reference).

But none of that has worked. Apparently, the only thing that's missing is the mobile data (although I haven't tested SMS yet). I'm stuck. Please give some advice, guys.

Thanks ahead of time.

[MENTION=7314841]ftaffoyam[/MENTION] Most people flashing builds of CM and related roms since about Nov 2014 report that they need to be on NE4 or newer firmware. (There are two releases since NE4. All are KitKat based.) You can find a recovery flashable file for the NE4 firmware here. Please be sure to read that post carefully before proceeding.

Hey everybody! New here, to this whole thing.

I received a handmedown phone with not much space on it.

Was already rooted prior.

But Cyanogen wasn't on it it was for the most part stock, however I wasn't able to update. In the hurry to update so I could play Pokemon Go (which btw doesn't support this device zzzzzz) I tried to get up to date, as I was running on 4.0.4 now with cyanogenmod on 5.1.1 and I received the No SIM card. I can still call, I can still text, just no data/MMS

I've downloaded the latest for - AT&T and other non-M devices. I747 - and when I try to run it in TWRP I get E:unable to open zip.

If I download it here on my computer I can open it no problem. Does anybody have a confirmed mirror to work? Or maybe could help me with why it would be unable to open? Like do I need to extract it into a folder first? BTW I can't use USB for some reason my computer doesn't detect my phone even with uninstalling reinstalling drivers/new USB cord.

I appreciate any help to get my data back.

Edit: I just had realized when trying to open the zip with es File Explorer It said I couldn't , so maybe the download was corrupted being downloaded over WiFi.

So I downloaded it on my computer emailed it to myself, opened and downloaded there. The file was able to be opened, I am now installing, here is to hoping this resolves my No SIM issue. <3

Edit 2: Now I'm in a boot loop, and yes I wiped both devlik and normal cache before booting after installing this. I can't even get back to TWRP. :(

Edit 3: With patience I was able to get into TWRP and wiped everything, reinstalled everything FRESH and back in boot loop again.

Hello,

I am trying to get Pokemon Go work on my Samsung Galaxy S3 (SGH-I747M) and I am have a bit of confusion doing so. Any information or suggestions to it would be greatly appreciated.

First off, I currently am on the stock rom (Firmware 4.0.4, rooted with TWRP), but I have downloaded and tried out CW13.

The issue with CW13 is that, like a lot of other people I see, their sim card is not detected; oddly enough I can still receive calls and texts. Since I can't send texts or calls, I decided to revert back to stock until I get more info.

What I have tried doing was updating my Baseband, and I am currently on I747MUMLJ1. I did see this post, but I am a bit confused. I see their the versions are I747UXXXXX, whereas my phone is I747M. From what I have read and understand, I need to use the I747M Firmware updates, and nothing else.

Next, they talk about KNOX, which I somewhat, but don't really understand. If I go to NE3, they mention I can't downgrade, which I don't know if it would cause an issue if I wanted to revert back to the stock 4.0.4 ROM. Unfortunately I am not too sure about that part.

If there is any other information you need, please let me know.

Thanks in advance for any suggestions,

~404

OK I'll try to help you out. There is a point upgrading the bootloader where you cannot go back or you will brick your phone. I think a JTAG repair is your only alternative for that. I have a I747 that has 4.1.1 and am studying how to upgrade to ne1 so I can run carbon ROM 4.4.4. Also I might try 5.1 but not sure right now. You must use the I 747M bootloaders as they are different from mine. Hopefully someone who is more sure of things will advise and correct as needed.

ok i have a question can i flash it ?? i have a weird phone meaning from the inside the board says i747, in download mode it says product name t999 and rom is i9300. whch phone do i have??
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] loocool2:
No need to post to three different threads. The model number inside the phone should be the model that you have.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
On the sticker under the battery. Unless the motherboard has been changed. Don't try to go by writing printed directly on the motherboard. For example, both my d2tmo (t999) and my d2att (i747) have i747 printed on the motherboard.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] scalzo:
Sorry to revive this thread but I'm looking to download the I747M modems but the links lead to sites that are full of malware. Does anyone know where I can find it?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jason2678:
I've not seen the i747M modems posted here. The typical advice for updating the i747M is to download the latest full firmware package from sammobile.com and flash it with odin.

This thread is terribly dated, and a bit of a trap these days. The newest modem the OP lists for the i747 is from jellybean. There are at least three newer modems out there for the d2att.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Dylan is awesome:
Yeah

Mee too. It downloads some random apk that requests for device administrator access

I think you can download the full firmware on updato.com and flash the modem from one of the stock roms
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] proza:
I downloaded the full firmware. I looked at itnside but do not know which one is the modem, could anyone tell me?

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] force70:

There was no modem in the leak. And I've never seen nor heard of a modem having a changelog
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] David Dee:
Technical question: Since I first flashed the LH1 update (full firmware, not just the modem), I have been having a problem with my handsfree bluetooth phone audio in my car. Prior to the update, I could consistently make and answers calls using car controls. Now, audio works well, but I have lost control from my car, I have do everything on the phone. Occasionally the car controls work, but very rare and usually within the first 2 minutes of connection only.

My question is could this be an issue with the modem? Does the modem drive the bluetooth connectivity and its settings? I was hoping to get some feedback before flashing back to the LE8, as I am not a big fan of changing modems in general given the risks.

Thanks in advance.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] meleii:
The bluetooth issue is more the likely a rom issue.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] David Dee:
I wish that were the case but unfortunately it started when I did the ota on stock Rogers rom and continued with aristidimus and the Bell jb leak.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
The modem does not have anything to do with Bluetooth or WiFi. Those are handled by kernel-mode drivers. You may want to try out the latest KT747 JB kernel, which updates the kernel drivers for both WiFi and Bluetooth. I don't think he has a Touchwiz-compatible JellyBean kernel yet, so you might be stuck using CM10 or AOKP until there is a "Sammy" JellyBean kernel available. I don't think the stock kernel will work with the updated drivers.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] David Dee:
Thanks man! That was exactly what I needed to know, saved me some frivolous modem surfing. I may go back to ics with ktoonz's kernel until someone makes a stock jb alternative.

Modem Subsystem

I tend to disagree respectfully based on this here:

http://www.xda-developers.com/android/find-out-virtually-everything-about-the-snapdragon-s4/

Look at the Modem Subsystem for SnapDragon
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
And all we're flashing is the "LTE World Modem" control software. GPS/WiFi/BT/FM (we don't have FM enabled in hardware) are each controlled with their own driver by the kernel. The kernel uses the RIL (Radio Interface Layer) driver to interface with the LTE modem's firmware, and it is the firmware which we are replacing. A "subsystem" is simply a logical group of similar components that may or may not share any hardware/drivers/firmware.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] David Dee:
K747 didn't end up fixing Bluetooth problem. Will have to try flashing le8 modem.

EDIT: I found a fix still on LH!! The car normally downloads my address book from the phone. To do this it requests permission upon pairing. I denied the permission and now I have full control of my phone via handsfree. The only downside is my contacts are not in my car, but I use Google voice search to dial anyways. I assume there was some software issue in the LH1 OTA not allowing downloading phone contacts and dialing/receiving calls simultaneously.

Hey guys of the canadian modems which is the newer one th LH1 or LE8? I put a screenshot of my build number. Thanks for your time guys

I have applied the LH1 modem update to my phone. How do I stop my phone from asking to install the latest software update now?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] meleii:
You can use titanium backup and freeze the fwupgrade app
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] zmore:
So I'm still on the original UCLEM modem (in the NYC area), and all's fine. Are there any actual changelogs for the two LG1 or LH1 modem updates, and/or any good experimental testing that proves anything? Seems like it's mostly a ricer placebo effect mucking with modems, and I never saw any compelling evidence to switch modems on my old Captivate either.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] meleii:
I would assume living in a large city most modems would be similar. Where I live there is mostly small towns and the difference in modems is dramatic.

Canadian modems need sorting as well, LH1 is the newest. Being in reverse order than stated threw me for a bit of loop.

I just flashed the ATT LH9 modem to my SG3 to see how it performs on my area (Tampa Bay). I had been on the ATT LH1 which was great. I will run it a few days and conduct some speed tests. Will advise.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] caanda45:
Good thread, in the old Captivate days I-897 At&T and the I 896 Rogers you could flash almost any modem including the I 9000 international versions....much more dangerous today!!!!! Good reminder!!!!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] morph3k:
How do you flash a modem?

It's been 2 years since i've used android. Back then we flashed radio's by booting up with volume up + power and had a file on our SD card named something particular and it updated.

Are modems the same thing? If not can you explain what they are. Either way, can someone tell me how to install one and check which one i have?

Thanks in advance!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] meleii:
There are directions in the OP. And a modem is the same as a radio.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] morph3k:
Missed that. Sorry.

How do I check what I currently have?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] meleii:
Go to settings about phone and look at your baseband.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] David Dee:
When I had my Desire Z, we flashed all radios without any issue. My best radio was the T-Mobile, which I ran on Rogers. Does anyone know why that is not the case here? Is it Sammy specific?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] stan.s:
You can let it download and postpone for a hour and move or delete the file in the /cache/fota folder. The update will make the phone reboot but won't find the *.cfg file and not bother you again. Once a cwm version is up that won't kill root then you can update.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
In this case, there are 2 variations of the SGS3 that have been grouped together because they use all the same hardware except the radio chip. The SGH-i747 is the AT&T model, while all Canadian carriers have the SGH-i747M. The M denotes devices with the different radio hardware. The rest of the hardware is identical between the 2 models, which is why we can share ROMs.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] caanda45:
Also in addition is that with the wrong modem/radio mismatch you can have the imei messed up and or missing!!!

---------- Post added at 04:42 PM ---------- Previous post was at 04:40 PM ----------

Here is one post....it was fixed by re-flashing the stock image...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
To be fair, if just flashing a stock ROM fixed it, then the IMEI wasn't "lost". A stock ROM won't have your IMEI in it unless you did a byte-for-byte backup of your phone when you first got it, using DD immediately after rooting. (Which I did, and at the time I had no idea why I was doing it except that I knew I could restore it no matter what ever happened to my phone.)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] David Dee:
I did the full dd backup as well. But wasn't it speculated that the imei is actually stored in the chipset which is why the only successful method of restore is through a qcn backup done using Qualcomm product support tools?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ElBeaner:
Will these modems work on JB roms?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] eatonjb:
roms have nothing to do with modems, so yes. they will work for jb
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
That's a good point. All I know for sure is that I've had IMEI issues after flashing the wrong modem in the past, and my only way to recover was to restore my DD images.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] David Dee:
Did you have a zero IMEI? If so, this would be the first confirmation I have seen of a full DD restore fixing the IMEI problem. You should send a PM to peoplearmy on this, as it could somehow assist in his work on fixing IMEI's. Sorry for the tangent OP, but this is very important stuff.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ManOnTheMoon:
sooo i searched for this but is there any advantage to flashing the modem if we use any cm10 roms? i mean are there any enhancements etc. are kernels that are being made going to get messed up?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
This is a separate piece of hardware that has its own software. It's like updating your router's software; It shouldn't affect your computer, but it will make things smoother sometimes.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bobloadmire:
I read that the modem software can also affect WIFI because they are on the same chip, is that true?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] stan.s:
yes. the LH1 and 9 remove the ability to pick a 2.4/5Ghz band too. I'm mixed about any improvements and it seems to prefer 2.4 over 5 Ghz no matter which has better reception. There's a app that you can install to switch/select bands.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
Nope.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] zmore:
I upgraded from UCALEM to LH9 just for the hell of it, and noticed no change in 4G or WiFi (nor did I really expect to notice anything).

So what's this about not being able to select a WiFi band? It works for me. Tried it just now on CM10 9/24 and it flawlessly switches between my 2.4 and 5GHz bands on my dualband router when I switch it between 2.4-only and 5-only. Simply shows my remembered 2.4 SSID as "Not in range" when I'm in 5-only mode.

(And I'm still amazed that I'm only the only N router in the area in a sea of dozens of G APs :))
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bobloadmire:
Well I was having problems stock, out of the box connecting to wifi on the original modem software, so I updated to the latest modem software, and I am still having the same issues, though I'm on CM10 now.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] stan.s:
There are plenty of reports with rooted stock and the 9 modem having issues and the wifi band switch removal. See my screen shot below, there's no reason to be connected to the 2.4Ghz band.

Last I checked, CyanogenMod doesn’t usually include modems so updates can be important.

I also have a area where other people with 5ghz are either rare or simply don't reach me (much more likely).
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] TheUnforgiven83:
Regarding the last couple or 3 posts, the modem doesn't have anything to do with your WiFi. The kernel is what handles the WiFi. The modem is only for the GSM/EDGE, UTMS/HSPA+, and LTE radios. The WiFi, Bluetooth, and NFC is in the kernel itself.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Ends:
Incorrect. Radio/modem handles any and all information that travels through the air. The kernel is the communication link between software and hardware.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
Alright, I'll prove you wrong Ends.

Install a Canadian modem on your phone. Nothing cellular-related will work, but I promise you'll still have Bluetooth, wifi, and NFC.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] stan.s:
Aren't some Canadian S3 equipped with different chips? I would think that Bell modems would be likely to work on AT&T phones, since they have the same GSM bands, though I have not checked the LTE ones (and those may not be compatible).
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
Bell, Rogers, SaskTel, and Telus are all using the same modem chip, wireless bands, and firmware. AT&T is using a different firmware, but I don't have a clue if the wireless bands are the same or not. I do know for a fact that AT&T firmware doesn't work on a Telus device (whoops), which means it wouldn't work on any Canadian device.

I should point out that I'm

only

talking about the I747(M) here; There are other Canadian carriers that have a different model entirely, the T999 (for AWS carriers like Mobilicity and Wind; also, T-Mobile has the T999) and I know that the modems will be completely incompatible from those devices.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Ends:
You can't disprove fact. The reason it will still work is because the instructions for nfc, wifi, and Bluetooth are the same no matter where you go. So when you flash a Canadian modem, you've really flashed nothing different from a us modem. Except for the frequency bands. Now I'm no expert. And don't understand everything. But trust me on this. Besides, think about this. The "kernel" can't send and receive any sort of signal. It's acts as a middle man between hardware and software.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] johnhazelwood:
Better proof is to uninstall your modem completely and then see what happens. My assumption is the kernel will laugh at you when you try to connect to a wireless network.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dstruct2k:
I'm tempted to try this, just to be able to say for certain what happens... I can just "dd if=/dev/null of=/dev/block/mmcblk0p#" and wipe the modem out, and then reinstall mine after, right? I mean, it shouldn't brick me?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] johnhazelwood:
I'm not sure it's worth risking your phone for. Might be safer to ask one of the kernel developers, if you want to know for sure.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Ends:
My assumption as well.
