[Q] Galaxy S3 Unknown ROM

Hi everyone, new android user here! I'll try to make this as brief as possible:
Recently purchased a used Unlocked Galaxy S3.
Currently using Bell Carrier on it and it works fine.
I noticed that even after restoring SuperSU was installed.
Checked download mode -> odin installed with custom binary
Checked to see if the phone has root access -> it does not
I wanted to try and flash it with a official ROM to completely restore factory settings but I don't know what the original carrier is so I don't know what ROM to download. I called a couple carriers but they have no record of the IMEI.
I'm fairly new to android and my past two days of google searching hasn't accomplished anything relative to my problem (although I know a lot more about the rooting community!) so I thought I'd ask here.
Is there any way to know what's going on here?
Can I restore the phone to factory firmware/ROM/etc.?
Here is some phone information:
Model: SGH-I747M
Android Version: 4.1.1
Baseband: I747MVLDLK4
Kernel: 3.0.31-538866
Build Number: JRO03L.I747MVLDLK4
Any help would be greatly appreciated!

Just go and download this program http://www.samsung.com/ca/support/usefulsoftware/KIES/JSP
Go to Tools > Firmware Install and Initialization
It will ask you for your model number and Serial number. It will use those to determine what stock ROM is correct for your phone.
It will then flash you to stock, just as Odin would, including the stock recovery.

It definitely looks like you are on the stock Jelly Bean firmware from Samsung. I747M is the Canadian model (747 is ATT). Your build number also looks to be the stock 4.1.1 based on the DLK4 build number! Just as the last guy said, grab kies or use Odin to go back to complete stock if you are not happy with what you have now. If your phone is showing custom binary flashes and you want to get rid of that, give Triangle Away a try! Good luck. :good:

Thank you! That worked like a charm! The device is now in a "normal" state and the binaries are "official".

Thanks for the advice! I'm not too concerned about the flash count, that's only really important your warranty to to be valid, right? But I'll look into it, it may be worth it anyway.
Thanks again everyone!

Definitely more info needed.
What ROM is on your device?
What bootloader did you install?
What modem/baseband/radio is on your device?
What method did you use to try to install the bootloader?
Is your phone still showing the correct IMEI in settings or 0 ? (Compare between that shown in settings and under the battery.)
It may be as simple as updating your modem, but I/we can't tell yet.

I'm new at this, in fact I have flashed by old Captivate several times but yet to flash my SGS3. Anyhow, I have spent many hours reading. Before doing anything I suggest, read, and read some more.
Don't flash back to 4.1.1 or 4.1.2 at this point. They will install an older bootloader than is currently on your phone. From what I have read, you narrowly escaped bricking your phone. You might want to read some of the threads regarding the 4.3 stock ROM and unbricking before making any changes in restoring your device.
You can probably fix this by flashing the modem that goes with the 4.3 series ROMs. It would also be the MJB flavor, although the MJ2 would probably work. Several of the 4.3 TouchWiz ROMs in the development forum have download links for the MJB modem. I would guess you were probably going to install one of them. I would recommend flashing the modem to see if that solves your issues before going ahead with the ROM flash.

The reason I didn't put a link in the previous posts was to get you to read about what you were doing as you searched for the modem. I am offering advice on things I have yet to experience on this device and only speaking second hand. My advice is only based on what I have read not on anything I have had to correct myself.
In truth I think you just stopped too soon in the process of what you were doing earlier. You said you installed the 4.3 bootloader in preparation to installing a 4.3 or later ROM that required the up to date bootloader. You didn't mention installing the current modem/baseband. You didn't mention trying to flash whatever ROM you had been considering.
You may be able to correct your device simply by installing the 4.3 modem. HERE is the modem thread, it is in the General Forum for our device. Make sure you pick the correct one. I don't know if your device will work well on the MJB bootloader and modem with a 4.1.1 ROM, from something I seem to recall reading I suspect it will.
Take this in steps. Install the correct modem, the one that matches your bootloader. See if that corrects you sim, data, and IMEI problems. If it does correct the issues, the next step is to decide if you want to stay on the 4.1.1 ROM or change to whatever ROM you had been considering. If you decide to change, make backups first. If it doesn't fix the problem while on 4.1.1 you may want to flash the version of the official 4.3 ROM enewman17 has provided on the development thread.
Take it one step at a time. Read about what you are about to do until you understand it well, all before doing anything. Make backups sequentially as you make each corrective step.
HTH.

thanks man for telling me what was wrong your an amazing human being and i love you (no homo) and thanks again a million thanks bro.

Did that modem fix some of the problems?

If your on 4.1.1 shouldn't you flash the DKL3 version or can't you just flash thru Odin the DLK3 stock ROM thru Odin Amd start all over again
I've been on 4.3 with that bootloader Amd have flashed back to 4.1 back to the baseband version DLK3 firmware. I would think being on 4.1 you should be able to reflash using Odin to fix the issue or flash the modem for 4.1 .

type in your model number here http://www.sammobile.com/firmwares/ i tryed looking for your phone I9070 and i see that there is not any firmware available for the USA so im guessing the device is not from the USA? also make sure you know which version of android you want. 2.3.6 is in some places and there is lots of 4.1.2 for other places.

this site should help me yes, like u said im not form USA, just form Poland. I found 2 firmwares for my phone form this website with 4.1.2 android, and that's what I'm looking for. But what does mean kies icon on this list? Because one of those firmwares doesn't have it and i dont know which one should i download.

[Q] Flash T210 4.4.2 firmware into T2105?

Hi, i bought a Galaxy Tab 3 7" Disney Edition but i don't care about kids stuffs, is it possible to flash it with latest T210 (ITV) firmware 4.4.2 with Odin?
My model is T2105 (ITV) and is still at 4.1.2
Thanks

It might work. Flash a custom (TWRP) recovery to backup the device first, then give it a try. Only problem is, anything could brick the device since there seems to be little to no info.
Some ideas:
Soe ifo on the recovery:
from http://forum.xda-developers.com/galaxy-tab-3/general/root-sm-t210-r-using-heimdall-t2936061
I used the Pit mapping for the T210. The recovery partition is "mmcblk0p10." I checked the partition info on my T210R using Partition Table by Lakshman. The T210R also has its Recovery partition on "mmcblk0p10," so I expect it to work no problem. And TWRP Odin flashables tend to be compatible with several 7.0 variants.

You can try The Nolekat Rom. It is fest Best Customrom for our Tab.

Sooooo.....
Did it work? Im curious as I got the T2105 tab for my kid and the darn thing is really slow for running Spider- Man Unlimited and some other apps
I want to put Cyanogenmod on it or some other rom with less crap

Ive been after the answer to this as well. I have the 2105 myself, and have TWRP installed and root, but not one single custom rom has worked. They just bootloop. Then you have to ODIN the stock rom. I have the original rom from sammobile, but they only have the factory 4.1.2 roms. Im wondering if a stock rom from the 210r or another Tab3 wifi rom would work.
It seems almost every tab3 from around the globe has been updated to 4.4.2 except this one...ive been checking sammobile everyday, but still no update for the 2105...

Your Bootloop prob is like the same as we have on The other device.
Flash a recovery with The Kitkat KK extension.

Well, actually its not a bootloop...it just reboots to recovery. Ill give a KK recovery a shot. any suggestions on which one would be the best? Or the recovery most likely to work? CWM or TWRP? Anything to get this off JB and onto KitKat...lol.. Apprecitae your help!

Yes, thats bootloop into recovery.
I prefere CWM or PhilzTouch on all my device.

Right on. Ill give those recoveries a shot. I have used CWM in the past (HTC Aria), but ive been using TWRP since i got the Galaxy Nexus. Ill give them both a try and report back in a few days... My internet connection sucks ass, so it takes hours to download a rom...

Its amazing that everyone is posting when they have question but no one cares to post their findings. I (also an owner of Galaxy Tab3 Kids T2105 bought in Australia) was fed up with the old and slow firmware. So, I decided to go ahead and flash a new firmware (T210XXBNI1 4.4.2 UK upgrade for SM-T210). First I tried to upgrade with Odin 3.9 but the process would fail after "Nand Write Start". Then I tried it with Odin ver. 3.07 and the process went smoothly and now I am a proud owner of Samsung Galaxy Tab3 with 4.4.2 Kitkat. It does feel a little bit swifter than the Jellybean. Anyways, so far so good. Will post if encountered any problem !

thanks for report thethakuri... i tried to do this too, but for me it doesnt work ... after i installed the 4.4.2, i had a black screen on boot and my tablet dont charge offline... so, i turned to 4.1.2... can you give me any sugesttion?

Update from me: Just upgraded my US SM-T2105 Kids tablet to the UK KK version as well (T210XXBOA3_T210BTUBOA2_Home.tar.md5). Did not work with Odin 3.11 but worked with 3.07 as mentioned above.

The Tab3 Kids is so far holding up very well with the 4.4.2 Firmware. Much more responsive.
Only issue I have is that it switches on when charging and the screen is not very responsive afterwards. A reboot fixes that.
I came across a post somewhere that there is a new bootloader required to fix that but I can't find the post anymore . If someone has that link please post it here. Thanks !

Did you ever find a fix for the screen issue? I'm going to give this a shot this weekend my daughter really wants pokemon go on her tablet!

Unfortunately I could not find it anymore.
Using ours now just with the new firmware and make it a conscious effort to switch it off after charging it. So far works fine.

Hi.
Will update to 4.4.2 would enable the move app to sd card?
Thank you.

any solution to remove kids feature

Root the device and uninstall using root uninstaller.

[Q] S3's Model Number changed after installing wrong ROM

I have an SGH-1747M which I am sure is the correct model since that it is what it said before I installed a new ROM and it is the model listed at the back of the phone, with the serial number. Recently, I installed a Lollipop ROM from this thread:
http://forum.xda-developers.com/galaxy-s3-sprint/development/rom-d2spr-cyanogenmod-12-1-t3074688
The ROM was meant for for the model SPH-L710, but it managed to be installed on my SGH-1747M phone. The ROM, although it works perfectly, has changed the model number on my phone to SPH-L710, and now my phone is only compatible with d2spr. I tried installing the ROM actually meant for my phone but I was unable to since my phone isn't d2att (the actual code for my phone) anymore. I tried installing a stock ROM through odin but it still won't recognize my phone as SGH-1747M.
I need to know how I can return back to my default model, since I have been told I will have network problems with the current ROM since it is not meant for my phone.

Visit this thread but don't flash anything else until you have read and asked for help there . Post there and explain your situation and even private message the op if you need to . http://forum.xda-developers.com/showthread.php?t=2363882

I would just be extremely careful with this. Do you make a nandroid backup before flashing? I would restore that or a previous one first. That will probably fix your problem.
Have you tried to flash one of the Unified CM 11 Zips? Those are kind of universal installer, see if that will fix your problem. http://download.cyanogenmod.org/?device=d2lte Download this and make sure you wipe everything a few times. Then install the zip.
People on here bricked devices by downgrading to certain modems/basebands after flasher a newer one. It seems like you have a newer modem, so I wouldn't try it. If you can still get into download mode, I would flash the latest tar for your device. I'm pretty sure it is an AT&T device or close variant.

The ROM, although it works perfectly, has changed the model number on my phone to SPH-L710, and now my phone is only compatible with d2spr. I tried installing the ROM actually meant for my phone but I was unable to since my phone isn't d2att (the actual code for my phone) anymore. I tried installing a stock ROM through odin but it still won't recognize my phone as SGH-1747M.
I need to know how I can return back to my default model, since I have been told I will have network problems with the current ROM since it is not meant for my phone.

I would just be extremely careful with this. Do you make a nandroid backup before flashing? I would restore that or a previous one first. That will probably fix your problem.
Have you tried to flash one of the Unified CM 11 Zips? Those are kind of universal installer, see if that will fix your problem. http://download.cyanogenmod.org/?device=d2lte Download this and make sure you wipe everything a few times. Then install the zip.
People on here bricked devices by downgrading to certain modems/basebands after flasher a newer one. It seems like you have a newer modem, so I wouldn't try it. If you can still get into download mode, I would flash the latest tar for your device. I'm pretty sure it is an AT&T device or close variant.
