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:

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.

Is the model # sgh-i747 according to the phone's label located underneath the battery? Did you try using Odin to install a stock ROM?

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.

Actually cm11 works fine for me as well as quantum. If you want a stock ROM I can find a link to the thread with the stock debloated 4.3 at&t ROM that I am running.

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.
I am able to install CWM and every 4.4.2 ROM I have tried installs without a problem.

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.
Hi,
I have a Sprint CDMA galaxy s3 device (of course) that had samsung stock rom 4.3 with Knox.
i rooted the device and disable knox with SuperUser, and then installed CM11.
now i want to go back to stock rom (downloaded from Sammobile).
do i need to worry from brick because of the knox? because it is disabled now, or is it ok to flash the stock rom via odin?
thanks in advance

I did this from CM10.2 last month and it worked for me, now i'm running cm11.
thanks, but it says DO NOT FLASH THIS IF YOU HAVE UPDATED TO MK3 (4.3)!!!! IT WILL CAUSE A HARD BRICK!!!
i had 4.3 before CM11, so i guess this is not relevant for me

I installed cm 10.2.1 coming from cm11 yesterday, it booted up the first time and worked great but after reboot it was stuck on Samsung screen, now i'm back to cm11, but i'm thinking of trying to go back to stock using odin. I get bored a lot I guess lol, and I can't have fear of bricking my devices if I'm flashing roms, have to learn somehow!

if it is interesting for someone, i flashed official stock 4.3 via odin successfully
You can flash the stock tar through Odin or even use dsxdias android kitchen to customize it so you don't have to flash the whole tar file and lose custom recovery or root.

Finally got Superuser installed and TWRP recovery working - Ran the Knox script. What ROMS will work with the new 4.3 OTA MJB besides slimrom?
I understand that if I update the ROM it shouldn't include a bootloader that is why I am asking this question???
Also since I have been using the stock 4.3 my battery is draining like a sieve. Anyone else having this issue?
Thanks,
Any rom designed for the d2att should work as long as the ROM is compatible with the bootloader.
Ok would any of the 4.3 or higher roms work?

I haven't tried that ROM but I have tried Cyanfox and Validus, both of which are based on 4.4.2. I think all ROMs will work with your phone's 4.3 bootloader.
The updater script is located \Meta-INF\com\Google\android\
Ok. I have the same concern. Rooted 4.3 att stock rom. I wonder if cyanogen rom 4.3 or 4.4 would work?

You should install a custom recovery first, then install a custom ROM.
Another question: Does the modem affect the rom in any way? I am on MJB from the last OTA update. I am just a little nervous because now that I am on 4.3 I cant use ODIN to flash the old stock rom anymore. All I have is a Nan backup of the current stock rom from ATT.
Yes. I installed cmw touch when I rooted. BTW I flashed CM11-M3. Working fine. But my GPS is screwed since I went back to stock 4.1.2 via Odin.

You can install an older ROM by using mobile Odin since mobile Odin does not flash a bootloader or modem.
mobile odin is 5 bucks. is there another alternative? I saw mobile odin lite but I was not sure what kernel to use? I have twrp recovery installed. is this a good recovery to use?
Quantum & Quantum Kernal
Quantum and quantum kernal are what I've been using since the first day I rooted me phone.
I recommend using them if your looking for a fast energy saving 4.4.2 KitKat rom.
I also used Odin on my PC to do my initial root/bootload/ROM etc. I'm sure you can Google and find an installer. Its what I did.
By the way Quantum is Spectacular!!!!

Install ClockworkMod 6.0.4.7 before any custom ROM!!!
It allows you to backup your current setup and recover to you working setup if needed on bad flash.
I also recmend the ROM Manager app from the play store it helps a lot.

The MJB bootloader in the official OTA 4.3 will prevent you from using an older bootloader. Odin .tar files of stock ROMs prior to 4.3 include bootloaders, installing them will brick your phone. The MJ2 bootloader from the leaked version of the 4.3 update will allow you to go back to 4.1.1 or 4.1.2. I have seen one mention of one of the devs using a difficult way to revert to older stock even after having the official 4.3 bootloader.
There is not a Odin .tar for the OTA 4.3 but enewman17 has provided a method to return to it from a custom ROM. AT&T I747 UCUEMJB Stock Restore

Latest Quantum is v3.5 and link is http://d-h.st/users/TommyTarts/?fld_id=33215#files Blue color name on first page of Quantum thread is actually link
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.

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)

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.
will a rom like this one work ?

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:

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.
