[Q] Flashed Lineage OS - modem problem - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I'm using a SGH-I747M (d2can) phone can flashed a d2att LineageOS rom. Everyone works except data. I'm able to receive/send texts and phone calls without issue. I've read that I may need to flash my modem, however I can't find a mirror anywhere. There was a complete list posted here a few years ago but all the links are dead. First of all, do you guys think it's a modem issue, and if so, where can I find the correct one to flash?
Edit:
So I've downloaded stock firmware and tried to extract the modem.bin file in order to flash it, but I can't find. I unzip the firmware, extract the md5 file, extract the NON-HLOS file, which has a bunch of modem.b01 files, but there's no modem.bin anywhere. Any advice?

Was the phone running the latest stock i747m ROM before flashing Lineage?

It was running a stock ROM, but I don't think it was the latest. I rooted the phone and Samsung stopped pushing updates because it was tampered with. I installed a stock rom (4.4.2) on the phone and it seems to be working okay, however is there anyway to install Lineage OS with the right modem?

The latest modem and bootloader is all that should be required. There is no specific modem that is made for Lineage.
Have you tried a different version of TWRP?

Does anyone have a link for lineages 14.1 sgh i747m? The links at official website aren't working.

Can't find Bootloader & Modem

Hello,
Trying to install the custom ROM cyanogen mod 11.
http://forum.xda-developers.com/showthread.php?t=2682905
First time I ever attempt to flash a custom rom.
In the guide it asks to DL Bootloader & Modem. My baseband is:
I747MVLUFOB3
I can't find any baseband corresponding to this one.
Here I found a firmware that correspond to my base band.
http://www.sammobile.com/firmwares/database/SGH-I747M/
Not sure if it is useful...
Any way to install the custom room??
Cheers

Which variant of the galaxy s3 do you have? You should be able to flash any ROM compatible with your phone using TWRP or Phil touch recovery.
I have the i747m (rogers canada). I have TWRP 2.8.7.0 & rooted with Kingo root. Somehow it was the only way to root it. Tried Towel root & odin but both were doing nothing.
TWRP was installed a long time ago. I recently made an update on kies (what a mistake sign...). I was on 4.4.2 before and after the firmware update on kies.
I got a spare S3 motherboard (with cpu etc.) I might try on that one first but I need to disassemble & assemble everything... not very tempting.
I usually just use odin and http://www.sammobile.com/firmwares/ to start fresh and root again when I want to upgrade bootloader and modems.
As you saw at sammobile, OB3 is the latest official release for the i747. You do not need to do anything to your baseband (modem) to run CM11. You may want to verify that your bootloader (firmware) matches the modem. This can be done from within TWRP. Go to the advanced menu and in the terminal enter
Code:
getprop ro.bootloader
You should get a return ending in OB3.
I suspect the CM 11 updater-script has not been updated to account for the just released OB3 firmware. If that is the case, you could always edit the script in the roms zip file.
@dawgdoc
When I entered the command, it returned me:
I747MVLUFOB3
Secondly, I have not tried to install CM11 (or the newer version CM12?). I do not know if it works. I just want to make sure I can flash and not brick my phone.
My phone is not the d2att (i747), it is d2can (i747m). I believe these two are very similar but enough different to cause problem.
So, can I install CM11 or 12?
You are talking about changing a zip file... The newb I am know how to do that, but what exactly - that he doesn't know. So I would rather not mess with that. I guess TWRP checks if the firmware of the bootloader / modem matches to those from a compatible list and simply updating that list would allow me to install the build?
I was thinking about this ROM:
http://forum.xda-developers.com/galaxy-s3-att/development/unofficial-cyanogenmod-12-t2968854
Don't know the exact difference with the CM12 but it says d2can.
However, the BaNkS GAPPS - GAPPS link does not work... I don't know what that is.

The unofficial CM12 -5.1.1 by @matrixzone is good for the i747M, aka d2can. If you have any doubts, ask on that thread if it is updated to run on OB3? Matrixzone is active on the forums and should respond to your question. Also I just checked the updater-script for the latest CM11 official nightly and it is set up to run on the i747M.
So, either should run with no problems for you.
What is the bootloader and modem version needed and how do I get them without getting a locked bootloader? I'm on i747M with 4.1.1 Stock rom with DLK4 modem and bootloader. There are newer bootloaders and modems that can be flashed through recovery but some people have been getting bricks when messing with bootloader.
THey say to use Official firmwares to have it update the bootloaders but which one is the proper firmware version to get the proper bootloader and modem version to allow DATA 4g LTE after flashing CM12.1 Lollipop rom?

Check my long post over there.

[SOLVED] I think my i747M may be soft bricked?

Hey all. I am fairly inexperienced when it comes to rooting, though I have done a few succesfully in the past. I currently have the newest version of TWRP installed on my Samsung I747M. The I747M I have is not from one of the major carriers, but as far as I am aware, the phone is factory network unlocked. Carrier is GCI, in Alaska.
I currently have a 4.4.2 Touchwiz Rom installed and started having problems after I attempted to flash the ROM Dandroid, which is 4.3 (http://forum.xda-developers.com/showthread.php?t=2121506). I had created a backup using TWRP before flashing the ROM and reverted back once I noticed the problem.
The main issue I am experiencing at this time is the Baseband Version, IMEI, and other information related to the modem is showing "Unknown" and features such as wifi will not toggle on.
I had also attempted to flash the most current version of the modem that I was able to find thru Odin. Odin showed the flash as successful. The version I flashed to the phone was I747MUMUEND3: modem_CWM_I747MUMUEND3.zip - 18.80 MB - April 3rd, 2014 (http://forum.xda-developers.com/showthread.php?t=1831898)
At this point, I can still get into recovery, download modem and I am able to boot up the phone and access most all functions. The next step I was going to try was going to be to flash back to stock firmware from sammobile's website (Was using to use the Roger's version of 4.4.2), though I don't want to cause more issues than I can handle or resolve thru software.
Any advice on how to proceed would be greatly appreciated or even just how to get the modem/wifi features functional again would be helpful. I'm just as happy staying on my current ROM at this point if I can get the phone fully functional again.
It's possible that the rom is not compatible with the kk modem and bootloader.
Flash cm12.1 to see if your imei comes back.

Forgot to mention, this is something I did try. I attempted to flash Cyanogen Mod 12.1 (Download: cm-12.1-20151017-NIGHTLY-d2att.zip (286.76 MB) ) and most recent nightly build & the most recent stable release (CM11) (Download: cm-11-20140210-SNAPSHOT-M3-d2att.zip (194.37 MB) ). When flashing these, I transferred the downloaded ZIP file to the internal storage of the phone in the root directory and attempted to run an install from TWRP. Both installs failed.
Since the phone is an i747m, I recommend flashing back to stock using Odin 3.07 and stock ROM file from here: http://www.sammobile.com/firmwares/database/SGH-I747M/
The i747m versions are interchangeable between Rogers, Telus, and Bell.
After flashing back to stock, install TWRP using Odin 3007 from here: https://dl.twrp.me/d2att/twrp-2.8.7.0-d2att.img.tar
Create a nandroid backup using TWRP and then try to flash a custom ROM again.

I'll give that a shot when I get home. Stock firmware was one of my next thoughts. I have it downloading at the measly 15 Kbps offered for free from sammobile so hopefully should be done by the time I get home & update this thread with any progress.
Another possibility is a custom kernel, if you are wishing to stay with TouchWiz and not wanting to upgrade your bootloader and modem past 4.3.
Some of the 4.4.2 TW roms will run on 4.3 bootloader and modems using one of ibuddler's kernels or ktoonsez's TW kernel. This was discussed most in the Likewise ROM thread and links to the various versions of ibuddler's kernel may be found there. It may have also been discussed in TMS3KK thread. The ktoonsez kernel can be found in its own thread.
But, you may really want to consider a newer ROM in order to change to something with the stagefright fixes. I think any of these may require the latest 4.4.2 bootloader and modem. (What say you @audit13?)

I'm not opposed to any of this. Mostly just trying to slim down this phone to the basics as much as I can and am quite open to any recommendations. Main thing I want to maximize is battery life & simplicity since this is for my wife and those are her major wants in a phone. I figure any kind of ROM that just covers the basics should cover my bases & would prefer one with a darker/black skin to maximize battery life w/ the OLED screen. I am in the process of flashing to the Roger's stock ROM as I type this w/ my fingers crossed.
Just to add, no over clocking or anything of that nature is desired. If I remember correctly I ended up putting the ktoonsez kernel on one of my handsets, either this Galaxy S3 or my Galaxy S5, though I can't recall which since it was so long ago.
Alright! So progress! Wifi, Baseband version, IMEI and all other missing information restored & now works w/ stock rom flash. In process of reflashing TWRP now.
Let us know what happens.
Still all good with TWRP installed. Have not flashed back on a custom ROM yet. After reviewing some of the above recommendations, I am kind of liking the looks & features of TMS3KK (http://forum.xda-developers.com/showthread.php?t=2725750) and feel it would suit my needs.
I factory reset, cleared cache, and cleared Dalvik thru TWRP & then made a back up. Prior to this, I confirmed everything was still working normally w/ phone fully loaded after TWRP was installed.
One of the things mentioned on the installation instructions for that ROM is the following:
---
Do not mix and match 4.3 firmware (bootloaders/modem) with the new 4.4.2 ones. You will hard brick and I warned you. This works the same as any 4.3 or ND8port ROM with 4.3 firmware and it can use the new 4.4.2 ones also.
Link to recovery flashable i747 and i747M 4.4.2 bootloader and modem packages: http://forum.xda-developers.com/gala...hable-t2856914
---
How would I go about confirming my current bootloader/modem versions to make sure they are both 4.4.2 before flashing this ROM? At the link provided, those files/links to the files were removed because they were causing some bricked devices per a note at the top of that thread. Here's a link to the thread I am referencing since the above link looks to be broken. (http://forum.xda-developers.com/gal...mware-ne4-ne6-nf2-recovery-flashable-t2856914)
If you flashed the latest stock rom, you are running the latest 4.4.2 bootoader and modem.
You can download and run the Samsung phone info app from the play store to confirm this.
You should be good to flash any d2lte or d2att rom.
I recommend not flashing any modem or bootoader from this point forward unless the bootoader and modem are newer than the currently installed botloader and modem. Also, the botloader and modem must be matched to each other.

Thank you so much for the help and information. I guess I never realized that the bootloader & modem were installed w/ the stock rom as I always have flashed those separately through Odin when needed. Definitely good information to have and not easy information to find. I have successfully got my custom ROM on there and am now fine-tuning it for the wife.

baseband imei unknown - tried virtually every modem out there - help

Hi everyone,
I know this problem is well known and solved many times already, but I'm not being able to solve it by myself. This is why I'm posting this thread as a last resort to try and get some help, just in case i missed something..
My phone is currently with unknown baseband and IMEI on stock 4.4.2 flashed via kies recovery. If I try to flash any 4.4.4 port ROM the phone locks up seconds after boot, it will only work with stock rom. I already tried a few modems i found on another threads but no success.
Can anyone help?
Thanks.

Isn't that a bit pointless? Maybe I'm missing the point, but if I already have flashed latest firmwares from both sammobile and kies, it kind of makes the point that modem and bootloader files from sammobile don't solve the problem, right?

Well truly doesnt seem pointless
I got my baseband resolved (Previously showed 'Unknown') by flashing pure stock rom (got from SamMobile) THROUGH ODIN so might be there is a point.
Try stock rom flashing from odin as according to me stock rom has everything in it radio(Baseband),boot(efs), system, etc etc
The unknown baseband and imei can be due to a modem and bootloader mismatch.
To confirm the bootloader and modem on the phone, install the Samsung Phone Info app from the play store to confirm the version.

Firmware Update

Hello,
I have been reading the forum trying to find information on how to flash a custom rom to my phone to upgrade my current firmware. I am currently on stock firmware 4.3 and my phone is rooted.
I am attempting to to upgrade my phone's firmware to a stable release (if possible) of firmware 5.0 or higher. Preferably the most stable release, as long as it is a minimum of 5.0.
I was reading several threads in the development section. However, a lot of the links in the threads are dead due to the age of them. When I do find a download, I am also unsure of what download type to use for my phone. My phone model is SGH-I747M (a Bell Canada phone). I see things at times referencing the AT&T I747 phone d2att downloads. But, I was unsure if any of that related to mine.
If anyone could point me in the right direction on where to go to begin flashing my phone to at least 5.0 it would be greatly appreciated.
Thank you!
I recommend flashing your phone to the latest ROM from sammobile.com. This will update both the bootloader and modem to the latest release. Then, flash TWRP and any custom ROM designed for the d2can, d2att, or d2lte.

Thank you for your response.
When coming back to reply to your post, I just noticed that you said to flash TWRP. I was reading so many different threads on here that I ended up flashing clockworkmod (version: 5.5.0.4).
I went to the sammobile site and downloaded the ROM package for the ATT phone. I hope that was the right one. However, upon attempted installation it says that the instillation was aborted.
I also tried flashing a ROM from the "[ROM][OFFICIAL][Lollipop 5.1.1][D2ATT] PAC-ROM LP MR1" thread. However, upon attempted installation a message pops up that says:
Warning: No file_contexts . This package is for device: d2att, d2lte, d2tmo; this device is d2spr.
Any assistance on this? My device definitely said SGH-I747M for the model number.
I performed all the factory reset steps before attempting to flash. So, now my phone doesn't boot up. I created a nandroid backup before doing all this. But, I'm not sure how to proceed with flashing a ROM.
Thanks!
You need to flash the stock rom for an i747m as the att s3 is the i747 if you want to return to stock.
CWM is outdated.

I apologize. I was mistaken from reading so many things over the last couple days. I double checked and it was the stock rom for i747m that I attempted to flash from here: http://www.sammobile.com/firmwares/database/SGH-I747M/
I downloaded the "Bell Mobile" package.
I also just flashed TWRP to my phone instead of clockworkmod. I attempted to flash the stock ROM package through TWRP and I now get this error message:
It says it is installing the zip file that I specified and then says:
Checking for md5 file...
Skipping MD5 check: no MD5 file found
Verifying zip signature....
Zip signature verification failed!
Is there something I'm overlooking? So far I've rooted my device, flashed TWRP, made a nandroid backup through both clockworkmod and TWRP and backed up both to my computer, downloaded the stock firmware from sammobile, inserted the zip file into my SD card, and attempted to flash through both clockworkmod and TWRP.
And thank you very much for your assistance. It doesn't seem like this forum gets much activity anymore. So, it is greatly appreciated.
Update: I also just verified that my version of TWRP is the most up to date release.

I was actually just about to come back into this thread to ask if I had to flash using Odin.
My phone showed up fine in Odin prior to flashing clockworkmod or TWRP. However, with TWRP flashed, Odin no longer recognizes my phone.
What could I do about this? If I need to remove TWRP and revert to stock recovery, I'm not sure how to.
I hope this is the last piece in solving this puzzle. :good:
Thanks!
Edit: I figured out why it wasn't being recognized in Odin. I was entering into recovery mode instead of download mode upon starting up the phone. That's my mistake. I'll be attempting the flash later in the day and will report back if everything goes fine, or if there's any issues, so this thread can be resolved in case any future users stumble upon it.
Are you in download mode when connected to Odin?

I got it all working now. I updated via the sammobile website and then flashed one of the ROMS found on this site in the development section.
So, all is good now. I've lost root after flashing one of the roms from the development section. But, I'll have to figure that out later.
For the most part, it is all resolved.
Thank you very much for your assistance. :good:
Depending on the rom, enabling root access may be found under developer options.

No connectivity after baseband downgrade (I9195)

I'm trying to use galaxsim unlock to unlock my I9195. The app says that I need a baseband ending with MJ7 or older.
At the moment the phone is on stock firmware
I9195XXUCOD3, which is android 4.4.2.
I have tried using Odin to flash two different modem files, one is a MJ7 modem file that I downloaded on its own, the other one is one that I extracted from some older 4.2.2 firmware. In both cases they flash successfully, the phone boots up, but there is neither mobile nor wifi connectivity. I assume that this is because the older modem file is not compatible with the newer firmware? I have successfully extracted modem files from stock ROMs and flashed them in the past, so I'm fairly sure I'm doing that bit properly.
I have also attempted flashing the older 4.2.2 firmware in it's entirety, rather than just the modem file, but it won't flash because the bootloader is older than the current one.
Any help for how I go from here would be greatly appreciated.
edit: i have also now tried flashing the I9195UBUBNE2 brazilian firmware that allows for downgrading from 4.4.2 to 4.2.2. even with this firmware, there is still no connectivity after i flash the MJ7 modem. so as far as i can establish, any MJ7 or older modem is not compatible with the later bootloader?
