[Q] SGH-i747m unknown baseband and imei - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

All, I have a rooted SGH-i747m, on which I had CM11. I replaced that with SlimBean recently, but lost my LTE. So, this morning I updated the modem to I747MUMUEND3 as is found in this thread: http://forum.xda-developers.com/showthread.php?t=1831898. Now I have no IMEI and baseband. Unfortunately I did NOT backup my EFS.
I have read so many posts and tried various things....but I just don't see any way to restore my IMEI and baseband (and get signal back!).
* I have tried a few of the other modems to no avail.
* I tried a restore from a backup I had of CM11 via CWM, but I'm guessing that doesn't backup the NVRAM settings.
* Attempts to use things like *#7284# yields "mobile network not available".
* the S3 doesn't seem to provide a COM port so I don't see how I could use NV-reader-writer even if I had a NVRAM backup file.....
Please advise.

What bootloader is on your phone? It may just be a case of a mismatch between the modem and bootloader.

Not quite sure.....but I did have CM11 on there and I believe a 4.4 bootloader was installed. I ended up reinstalling stock firmware, then reinstalling slim bean and everything works now.

I'm having a similar issue, no modem and carrier support after restoring to an earlier, stock ROM than was on my phone (sgh-i747) before OTA soft-bricked it.
My bootloader is now NJ1 and I can't find or flash a bootloader_modem package to update my modem, attempt to do so fails with status 7 and baseband version remains blank... while everything else on my phone is MJB = mismatch.
I'd like to know exactly what you did to fix yours, dolhop, but it may not help me as I'm already at an NJ1 bootloader

I don't even know how to check which bootloader I am using. I simply used odin to reflash a stock from from sammobile from download mode. That worked. From there I used odin to flash CWM, then used CWM to flash in slim bean.

Status 7 error can be due to an outdate recovery. Are you running the latest CWM or TWRP?

Since you have an i747, you cannot use any firmware from sammobile.com on your phone.

Thanks for the reply, audit13
My CWM is version 6.0.2.3, not most current (6.0.4.7 is latest?) - I got CWM and Team Epic Custom Recovery v5 bundled on androidcentral when I first rooted my phone
I looked at sammobile.com and only saw 4.1.1 for ATT US and didn't even bother... I got the 4.3 stock recovery I flashed here, which resurrected by phone, but unfortunately it was already at 4.4.x, aaaaand now I've got no baseband (mismatch)

[Q] Baseband Version & IMEI Unknown

Hi all,
Ran into some issues with a new phone, hopefully someone can help me out. I've been reading and tried a few things, but no dice. I purchased an unlocked AT&T Galaxy S3 off Ebay, then proceeded to install CWM recovery, take a nandroid backup of stock (v4.0.4), and installed CM 10.2. Upon inserting my T-Mobile sim card and trying to configure the phone, it complained about me needing to insert a sim card and I subsequently noticed that both my Baseband Version, Network, Mobile Network Type, My Phone Number and IMEI are reporting as Unknown.
I've tried restoring my nandroid backup to stock, same items are reporting as Unknown. Trying to flash several stock images with Odin results in 'SW Rev Check Fail: Fused 2 > Binary 0'. I'm guessing this is since CM 10.2 is v4.3. I've tried using NV-items_reader_writer to read/write the IMEI, but it won't connect, complaining 'Phone does not accept SPC. SPC is not correct.' I've run Triangle Away under CM 10.2 with no change to Odin results.
Currently, Download Mode reports:
SGH-I747
Custom Binary Download: No
Current Binary: Samsung Official
System Status: Official
Qualcomm Secureboot: Enable

Does anyone have any suggestions on next steps?
I have never been able to run cm 10.2. I have tried several times and always get the Sim card error and no signal. I don't know about the imei or the baseband, because I didn't check mine. I am on at&t and have the newest boot loader and modem. I just flashed a different ROM and my phone worked fine, but like I said I don't know what my baseband and imei showed.

correct, the model number is sgh-i747 as shown underneath the battery. i've tried flashing several stock 4.1.1 roms using Odin, but each time i'm greeted with:

do you have any suggestions on stock roms to try flashing? i think i need 4.3 for the bootloader(?) to allow it, and as far as i can tell there isn't an official 4.3 image for AT&T's i747. perhaps i'll give the 4.3 leak a try, or try flashing a non-CM rom as bellifritz suggests.

Look through this thread. Scroll down to where it says Roms and the one marked debloated is what I'm running. There is an odedex version and a deodexed version. I'm running the odexed which is closer to stock but without all the at&t stuff.

Thanks for the link. I actually have an i747m and do not want to go near 4.3 because of Knox. Also, I can go back to stock, reset the counters, and keep my warranty.

Your phone is an i747 so you should stick with stock AT&T ROMs. There is a stock 4.04 on samfirmware that you can try.

Something is not right with all that. The only reason you should have that dialogue about fused and binary stuff is with the new 4.3 bootloader, but 4.0.4 firmware is ICS. Be careful what you flash until you know for certain which bootloader you are using.
Galaxy S3 ATT Baseband IMEI Unknown
I have a samsung Galaxy S3 AT&T (I747). AT&T pushed Kitkat 4.4.2 update last night and after installing my phone was stuck at AT&T logo. AT&T says warranty is over, so they can't do anything.
I flashed JB official stock ROM and then multiple other ROMs but my Baseband and IMEI shows 'unknown'.
WIfi connection is working fine, but no network connection. Desperately need help...
Install terminal emulator from play store and enter this:
getprop ro.bootloader
Post here what firmware build it returns. Also which Rom exactly that you are currently running.
Firmware: I747UCUFNE4
It's currently running Android 4.3, Build: JSS15J.I747UCUEMJB
Try flashing one of the KK touchwiz roms. Might be that running the 4.3 rom is giving issues with the NE4 modem. If that doesn't work you may just need to reflash the modem. (You didn't flash the 4.3 modem did you?)
I think i flashed CWM_I747CUEMJB modem. is it good or bad?
once i flash KK Touchwiz ROM, do i need to flash modem also? if yes, which one?
Actually, since you are already on NE4 firmware, but you said you may have flashed the 4.3 modem, that would most likely be the cause of your issue. Try just flashing the NE4 modem and hopefully thatll take care of it for you. I just uploaded it, see below:
NOTE TO ALL!!!!!!
WARNING!!!
WARNING!!!
WARNING!!!
DO NOT FLASH THIS MODEM UNLESS YOU ARE ALREADY ON THE UCUFNE4 FIRMWARE!!!!! THIS WILL BRICK YOUR DEVICE IF FLASHED ON 4.3 FIRMWARE!!!!!!!
THIS IS ONLY SAFE TO FLASH IF YOU ARE ON 4.4.2, NE4, I747 FIRMWARE AND BOOTLOADER!!!
ATT_GalaxyS3_UCUFNE4_Modem
maybe a stupid question, but because of your warning just want to confirm:
the terminal command returned the type of boot loader which is NE4. do i need to confirm the firmware also, if yes, how? or is it the same?
Checking the bootloader confirms that you are on that same firmware. So if it said you have the NE4 bootloader, you also have that firmware so you are safe to flash.
---------- Post added at 06:12 PM ---------- Previous post was at 06:10 PM ----------
And its never a stupid question when making sure you fully understand something like this prior to flashing! If in doubt.....ask!
Thanks a lot! it worked. my Baseband and IMEI are back and it's connected to AT&T network.
But the moment i flash modem, WiFi stops working. I tried it multiple times, WiFi works after flashing JB ROM and stops working after flashing Modem. When in settings i try to turn the WiFi on, it turns off automatically.
There is also constant security information: "The device has detected an application attempting to perform action that are not permitted. These actions have been blocked". This also happens on wifi-on action.
Open the SuperSU app and it will ask if you want to disable Knox. Tell it yes and those security notifications will stop.
For wifi, if you are running a 4.4.2 rom, you will need ktoonsez' kt747 kernel. If on a 4.3 rom you need the MJ2 kernel.

[Q] Update to 4.3 from rooted 4.1.1

Could some one answer a few questions I have on how to go from rooted 4.1.1 to latest build. I have read and DL'd the zip from the "[LEAK] AT&T 4.3 UCUEMJ2 (Root & Knox versions)" thread and was wondering if the the rom can be loaded directly from CM recovery. Is the new bootloader required or optional?

Have you checked to see if you can get OTA update or update via the latest version of Kies? I was able to update from 4.1.1 to 4.3 with 2 different pre-rooted i747s - one officially via OTA and the other by flashing the same zips you refer to via cm recovery so maybe that answers your question. Before taking the one-way trip to 4.3, however, be sure you are done messing with your phone at the older firmware including unlocking, if required, as you may not be able to go back.

I'm not aware there is any Odin flashable file for 4.3 yet. You may follow the steps in the link below for manual update via CM...
http://www.smartphonejam.com/2013/1...fficial-android43-i747ucuemjb-ota-update.html
You didn't say if you tried the OTA update? If you want to remain on stock, this is always the safest bet. If you are currently on official 4.1.1 you should be able to get this via WiFi with a valid AT&T sim card in your phone.
Me personally would avoid the official OTA update unless you're absolutely sure you want to keep it. Once you take the bootloader MJB you cannot flash any stock rom anymore unless you have an I747M then you can only flash the official 4.3.
I am on the MJ2 leak bootloader and have no issues, running S3Rx with the MJB modem phone runs great, if something happens I can simply flash anything I want to with Odin.

Exactly. I have also stayed away from the official 4.3. I have no idea why so many people around here just insist that their phone be on the latest update. Ok, the ones that had some major issues previously I could see, and yes you're going to have your exceptions whose phones will work just fine on 4.3. But all this 4.3 has done is create even more issues, with no flash-able firmware to go back to when something goes wrong. Some say there is no major reason not to update, but I say that there is no major reason to update, as most never give a reason to why they want to update. I just don't get it, other than these updates have become like new toys, just something new to play with.

shortydoggg thanks for your post and you actually hit the nail on the head. I can't think of reason I NEED to update, I just get bored and like to play. My warranty is up so voiding that isn't an issue and my 4.1.1 runs just fine, but by playing I learn so I like to play. 4.3 has a few nice features but if prevents the phone from being re-flashed then the risks most-likely aren't worth the benefits. I am just doing my due diligence, researching and asking questions. I really appreciate all the input and advice I get from forums such as this so I can make an intelligent decision.

If you really want to try and want it to be reversible you can use the 4.3 leaked MJ2 bootloader if you decide you don't like the 4.3 stuff you can simply Odin back to stock. But if you use the MJB bootloader you cannot.

Thanks. It does get into download mode. Is there an Odin flashable file for the MJ2 and, if so, where can I find this? I'm wary about flashing an older ROM (e.g. 4.1.1) to avoid any further conflicts as I still have the official MJB modem or can this be done safely?
I've tried clearing the system and reflashing but it was the same result or perhaps I wasn't doing this the right way?

I have been told by very reliable sources that you can Odin to an older version safely regardless of modem as long as the bootloader isn't MJB or MK5 so I am pretty confident it is safe. At this point there isn't too much to loose.

Odining to an older ROM is apparently not an option as this is isn't working. Thankfully, the phone is still booting into both download and recovery modes without difficulty so there is hope. I flashed CWM recovery via Odin thinking the problem may perhaps be with TWRP. However, the result was the same and the phone kept booting back into recovery mode rather than to the system. I also tried to see if was the bootloader so I flashed the MJB bootloader as well as reflashed the MJ2 system zip. The flashings were successful so, at least, it's unlikely to be a bootloader conflict but still the system will not boot.
Will greatly appreciate steers from the community on how to get the thing back working. n Thanks

Finally got it back up and running today. Cant be sure what really led to the soft brick but I simply wiped out everything in TWRP mode and then re-flashed the (MJ2) system, modem and kernel zips. This time it worked, I'd tried the same thing before but without the kernel. Now I'm back to the same configuration as before.

I made a mistake, I installed the ROM [ ROM] [TouchWiz 4.4.2] *eZKAT*, then flashed with the patch wifi, as it not to work I returned to my previous ROM DN3 v3.2 but since I do not have IMEI anymore.
I have even to flasher with official ROM but anything makes for it, always not of baseband.
Official ROM used:
N7105XXDMB6_N7105XEFDMB3_N7105XXDMB1_HO ME.tar.md5 and N7105XXALJ5
How can't get my imei ?
You made a backup of your EFS.
If you didn't then it will be really hard to restore your own IMEI. You shouldn't try to revert back your bootloader.
Give more info what you did exactly?
Which bootloader have dn3 rom?
Here's the correct way to do things

For my EFS i have a backup done with TWRP.
My phone: n7105 LTE
when i was DN3 and before flash [ROM][TouchWiz 4.4.2] *eZKAT*, i have 4.1.2 bootloader.
baseband : N7105XXUEMJ9
bootloader : N7105XXDMA5
OK what i do, well first i flashed eZKAT and flash wifi patch (because wifi don't work and after still don't)
Then reboot and see that i lost my IMEI
Then i tryed to flash 4.1.2 rom stock and restore EFS with TWRP, but not work still no IMEI
Finaly i restore my DN3 4.3 v3.2 from TWRP and have
now no baseband
bootloader: N7105XXDMB6
Now i don't no what is my bootloader
There is an app phone info samsung on the play store. Get it and check . here are many threads started by user who tried to restore their IMEI. Try to search in the forum you will find many useful info.
And you have your backup so it should not be so bad. Me I m not rooted stock so I'm not so qualified to guide you. Search the forum.

first of all go to sammobile and get 4.3 stock rom for your region. Then boot into recovery and wipe everything. Then flash the stock rom u downloaded via odin.if you have not flashed the ezkat rom via odin. Then this will solve your problem. Most probably you would have flashed the ezkat rom via recovery so its no big deal as flashimg via recovery does not change your bootloader. So go flash a stock rom 4.3 version via odin.it should silve your problem if it still exist then root your phone(after flashing stock 4.3 rom via odin) then get twrp recovery and try restoring your efs.good lu k

Did you flash stock via odin? Try restoring efs backup.

Did u make a titanium backup when you were on dn3 rom. If yes then you can restore your dn3 rom and restore titanium backup( both system and user apps) and if nothing works then probably just flash stock rom dont root it and take it to service center.

Also if you want to flash 4.4 then dont flash stock first. My advice would be to first flash any aosp rom 4.4 via recovery( after full wipe offcourse) then again try restoring your efs

You haven't made backup of EFS and you're also flashing incorrect bootloaders to your device?
I have no sympathy for you.

Don't burn him too hard, people are sometimes too ready to offer their suggestions, and, well, yes sometimes people are too willing to act before understanding and confirming.
Anyway. IF you've flashed a 4.3+ stock rom in odin, booted to recovery and full wiped and it still doesn't work, then it looks like flashing a stock rom in odin isn't going to cut it. My next step would be google and xda, find what others have done, and not take the first answer without confirmation. Eventually if all else fails I would get the the right pit file and stock rom and flash both in odin with pit and erase all nand checked as well as the normal two, again boot to recovery and full wipe. Anyway, I do not know if that will relieve your issue at all. But from that point I would imagine installing a custom recovery and restoring a known working backup isn't a bad shout, of cause tripping knox as I imagine has already been done.

Exactly my point.
I keep telling him he kinda has 4.3 bootloader from tmobile/at&t and can't downgrade bootloader so try upgrading to 4.4 stock see if that fixes it. Unless his bootloader gets upgrade he'll be stuck with param.bin file in wrong place and no signal

Before flashing, I wanted to keep my 4.2.1 bootloader but it does not seem possible.
Now i am on 4.4 bootloader :crying: My n7105 is knoxed and "warranty void" is 1

I know but that was the only way I could think of to get baseband back. I'm glad you are up and running and please feel free to ask before you flash something if it is ok for your device.

[Q] IMEI/Baseband Unknown after 4.4.2 OTA attempt

I have an AT&T I747, and tried to install the OTA update to 4.4.2. After completing & rebooting, the phone got stuck on the white AT&T screen. I flashed stock 4.3 back onto the device, but now have no phone/mobile networks, and the IMEI & Baseband show as "Unknown". I do have Wifi. I've seen some similar issues on the forums but nothing exact - tried flashing the MJB modem (flashed fine, but no change), and tried flashing the MJB modem & bootloader (get "assert failed" followed by several getprop commands). After a couple of days chasing this, thought I should ask rather than keep stumbling & possibly making things worse. Anyone have any advice?
I was rooted but otherwise stock when I tried to do the OTA update.
I'm using TWRP 2.6.3.1 to flash, ODIN 3.07, and the files I flashed were (from links found in this forum):
4.3: I747UCUEMJB_2024954_REV04_user_low_ship.tar.md5
MJB modem: d2att_I747UCUEMJB_modem.zip
MJB modem & bootloader: d2att_I747UCUEMJB_modem.zip
Any help greatly appreciated.
Try flashing a 4.4.2 touchwiz rom and factory resetting.
DO NOT try to flash the 4.3 bootloader or firmware! You are lucky it didn't flash or you'd now be hard bricked! The MJB modem may not work on the NE4 firmware, so make sure you have that modem.

Thanks for the advice! So would you recommend flashing 4.4.2 first, and then an NE4 modem if I don't have it, or reverse that order?

which ROM and files did you flash? in what order? I'm in the same boat. It works in 4.3 with "Baseband Unknown". However, If I try to update to 4.4.2 , the phone will freeze after "Samsung" logo.
What firmware are you on?
Install terminal emulator and enter this:
getprop ro.bootloader
If it returns NE4, that's the modem you need. If it returns MJB or MJ2, do not flash the NE4 modem or it'll hard brick. Basically, you should use whatever modem matches the firmware/bootloader version you currently are running.

Was at stock 4.3 . Received OTA update and froze in the middle of updating.
I used this to get back to stock 4.3 I747UCUEMJB_2024954_REV04_user_low_ship.tar.md5
Everything works , but Baseband Unknown. If flashed NE4 modem, Baseband is back and phone working again, but can't turn on Wifi.

- install TWRP and flashed 4.4.2 stock zip -> freeze after Samsung logo after reboot
- restored to stock 4.3 again, install TWRP and flashed 4.4.2 OTA zip -> freeze after Samsung logo after reboot
- restored to stock 4.3 again, used stock recovery and flashed 4.4.2 OTA zip -> freeze after Samsung logo after reboot
Ok, this is what happens with wifi....
4.3 firmware with 4.4.2 rom = no wifi
4.4.2 firmware with a 4.3 rom = no wifi
In both cases you need a custom kernel. Since you are updated to 4.4.2 firmware, if you want to use a 4.3 rom, you will have to flash either the MJ2 or kt747 kernel for wifi to work. The NE4 modem is the only modem you can use now.
Your boot hangs will be solved by factory resetting. I doubt there's any way around this at this point.
I suggest flashing the NE4 stock rom from enewman17. Then factory reset. It should reboot and work fine now.

Thx for the tips. Will try soon.
However, once the phone froze after Samsung logo, I could not access custom recovery anymore. In the case of stock recovery, I could get back to it but there were no point. Phone still froze after Wipe.
Try refreshing your recovery with Odin. Try rebooting recovery again. Then try to factory reset before flashing the rom, and again afterwards.
Good luck and let me know how it goes!

After 5 hours working on this phone, I think I'm happy which what I have now.
1- Restored back to stock 4.3
2- Flash custom recovery
3- Flash NE4 modem
4- Flash ktoonsez kernel Touchwiz JELLYBEAN 4.3 VERSIONS
Everything is working now. I will not update this to 4.4.2 b/c no matter which ways I used to go to 4.4.2 either through custom or stock recovery, phone would freeze after Samsung logo ( already did factory reset before and after flashing ROM/update)
Thx for your help.

That ROM appears to have a pretty old base and uses a stock kernel, and you're phone is on relatively recent kitkat bootloader and modem. You might be able to get everything working by flashing a custom kernel.

This one is the most up to date. It's Perseus' unofficial version.
Make a backup of boot using your recovery before you flash the kernel. It will be very fast; probably a 10 - 20 MB backup. Then flash the new kernel. That way if you bootloop or it doesn't work out for some reason, you can boot back into recovery and restore that backup of boot to get back to your original kernel.
If that doesn't work, you can try some of the other touchwiz kernels, or just update to a more current ROM.

Before you mess with kernels, have you made sure you're on the right APN for T-Mo? Just thought I'd ask since that ROM supports a wide range of carriers.

You should be able to get back into recovery and restore the backup you made of boot to restore your original kernel, or just flash the ROM zip over again. Either way will get your ROM working again.
I suspect that old 4.1.2 jellybean ROM you're trying to run just doesn't have right ril libs/binaries to work right with the kitkat-gen modem on your phone. Did it let you edit APN's and show your IMEI in the ROM? Either of those not working is usually a sign the ROM just doesn't know how to work with the modem on the phone.
You'll probably have better luck if you switch to a newer touchwiz ROM based on the NE4 ROM that matches the firmware on your phone or an AOSP ROM.

You are on a 4.4 bootloader and modem. That ROM says you need a 4.4 bootloader and modem in big red letters right in the OP. I think it should work with the firmware on your phone. :good:
---------- Post added at 03:16 PM ---------- Previous post was at 03:02 PM ----------
Whatever you do, do not try to downgrade your bootloader and modem to work with older ROMs. Not sure if you've read this about this phone yet or not, so I'll put it out there. The 4.3 and 4.4 bootloaders and modems (MJB, NE4, NJ1, & NJ2) always need to be matched. Some people have reported hard bricks trying to flash a modem that doesn't match their bootloader, and those 4.3 and 4.4 bootloaders cannot be downgraded. The result of attempting to downgrade those bootloaders is always a hard brick.
