Hi all, I have an SGH-i747 with ver 4.0.4 which has been rooted. I will like to update my version systematically with the original updates i believe there where from 4.0.4 to 4.1.1 then 4.1.2. then 4.3, 4.4.2 etcc.. its there a place where i can find the original ups, my phone will not take the original firmware updates on its own. Reason is once i try to flash any ROM pass 4.1.1 i loose the Mobile Data getting the no sim inserted msg and no signal, forcing me to go back the original state in order to work. seems there is a problem with the modem once i go pass 4.1.1. .. thank you.
What bootloader version is on the phone? Where did you get the firmware to flash? You're using desktop Odin to flash?
Are ota updates an option for you? If they are you can unroot and flash the stock recovery; it might be easiest just to Odin back to stock.
Otherwise enewman has posted firmware updates to xda. They are bootloader + modem zips you can flash in custom recovery. You have to flash them incrementally, mjb then ne4 then nj1. Search the forum here and you'll find them. Just be careful and read read read those threads. Messing with bootloaders is the best way to hard brick this phone.
I'm in a similar situation - I've been on a custom version of the Stock ROM for 4.1.2 - never bothered to update the bootloader because I had the soft unlock done, didn't want to lose it. Now I'm bored with it. I'd love to get up to 4.4, or even a 5.0 ROM... but not sure the steps needed to do so. I'm vaguely aware that I have to update the bootloader/kernel, etc... but it seems like I'm 4 years behind the curve with all the ROMs and threads about bootloaders, and I've lost my touch.
That thread with the list of bootloaders sounds good though, I'll go looking for it to start I guess.

Here you go. This TLDR post has all enewman's firmware update threads linked to it.

Thanks! I'll give it a look, down a couple of shots of liquid courage, and give it a go this weekend.
EDIT: Yikes, didn't take long for that to fizzle out. I'm using a i747M. Noticed that my current baseband version isn't listed anywhere on that thread. Hmmm. Oh well, guess I'll do some more digging later...
With an i747m, you can flash the latest 4.4.2 using firmware from sammobile.com and desktop Odin.
Do I need to do them in sequence, or can I jump to the latest? I'm assuming once I've flashed the stock firmware, I can load any current custom ROM?
@gfinockio, is your phone sim unlocked? If not and you don't see any mention of the warranty bit in download mode, you could flash back to stock 4.1.1, use the free method to sim unlock, and then run OTA updates until you are running the latest ROM. OTA updates are the safest route to upgrade the phone.
If you phone is sim unlocked already, you could flash directly to the latest ROM; however, you will not be able to downgrade the bootloader as any attempts to downgrade the bootloader could hard brick you phone.

I used the "free unlock" in 4.1.2 (so it's unlocked) but I thought when you upgraded the bootloader you lost that lock. Now that I believe that isn't the case (and I've used a different tool to unlock as well), I may just try the OTA updates. I was with MTS (Manitoba), but now I'm with Rogers, so I guess I would just use the Rogers OTA images to upgrade from 4.1.2 to 4.4? Do I use Odin or whatever to do that? Once I upgrade to a "stock" image, won't the updater just prompt me to upgrade again and again until I'm "up to date"?
Unlocking the phone via code or the free method is permanent even after upgrading the ROM, bootloader, and modem.
The carrier ROMs for the i747m are pretty much identical but I always recommend sticking with the original carrier's ROM. If you download the stock image from sammobile.com, use Odin to flash the ROM.
OTA updates will not work with a rooted stock ROM too.
When i search for the stock firmware on sammobile for the i747m, it doesn't have any listings. Are you able to find it on there? I don't see it.
Search for the sgh-i747m.

i have rooted and unlocked galaxy s3(i don't know if it is t999 or i747)the imei and boatloader are for t999 and the android build is i747mvldlk4 4.1.1 official rom and i want to flash new rom but i don't know what i have to flash (t999 roms or i747)please help me....
What does it day in download mode? What about the baseband/modem version?
Best way to know for sure is to install terminal emulator and enter this:
getprop ro.bootloader
You may simply have a T999 running on an I747 based rom. The two are very compatible when it comes to custom roms.
Since it sounds like you are on pretty old firmware, you will probably need to fully update it before flashing a newer rom. Just remember to only flash firmware for your model device. So if it's a T999 do not flash I747 firmware. Once updated you can then flash custom roms from either device.
(Also check the sticker under the battery to see what model it says)
baseband:t999uvdmd5 and modem board is msm8260a
What about the bootloader?
boatloader:t999uvdmd5
And just for good measure, check the sticker under the battery.
You are currently running on T999 base firmware with an I747 based rom, so you can be pretty certain you've got a T999 model.
You'll want to flash one of the two latest firmwares for the T999. (NC2 or OH1 if I'm remembering correctly) (note that some roms may not flash on the newest OH1 firmware if they have been updated recently, so you may want to go with NC2 to make things a little easier for now.)
After flashing your firmware, flash a custom recovery and then from the recovery flash your choice of rom.
Hope that helps and good luck!
thanks so much for help....but i want to ask about the files which i need to download when i flash nc2 firmware please(do i need to download any files for modem and kernel or this files are downloaded automatially with the firmware file??
When you are dealing with firmware, it includes everything, unless otherwise stated. Download and unzip the firmware package. Then flash the .tar.md5 file with Odin. Back up data first of course, just in case.
Doing this will give you a fully updated, stock, unrooted device. Reroot using Towel root, or flash recovery then a rom if you choose.
If you haven't already, I suggest reading the first few posts of my firmware thread (sticky in dev section). There's already a lot explained there.
does flashing t999uvuenc2 relock my mobile network..and if that will happens what can i do to unlock without code
Once the phone has been unlocked via code or the free method, the phone should remain unlocked after flashing ROMs.
Yup, the unlock is permanent. You can safely flash firmware, roms, etc.
ihave flashed cm12.1 d2tmo on my t999.but the features of camera like full HD video recording and face detecting were lost..can I restore them on this rom
Hello All,
I am currently looking at different ways to try and update my device to dojc or doj7. Right now it is on DOH6 and seems like I have a few random glitches with the way it works and crashes. I am rooted currently with engineering bootloader with a custom recovery. I am thinking of one of two paths and wondering what might be the better of the two options in your opinion.
First, create a firmware file to flash with Odin that does not have the bootload file in it and flash that. Then root the device again the same way I did with the DOH6 root method and engineering bootloader. Stay on that install from Samsung and just root it.
Second, install a custom rom with that new version as a base (I think I remember seeing some stock rooted roms). and then upgrade the modem only with odin. Not sure if there is anything else other that the modem that would need to be updated with Odin.
I am just not sure if that second option would work if the firmware is too different to work with it. Any opinions on which might be the better option? How have you been able to update to DOJ7 or DOJC and root without worrying about Knox? And input would be greatly appreciated.
Couldn't you just flash a custom Rom and flash the new modem with Odin?
Would that work okay guys? I think that should be fine and leave the bootloader on 5.0 engineering and it won't trip Knox.
I have a Canadian Galaxy S3, on 4.1.1 DLK4 Official. I rooted it, and have TWRP.
I want to upgrade my rom to a CM12/13 but of course with root and custom recovery, OTA updates are blocked.
I need newer bootloaders and modem to run the newer android versions.
Should I install them now, while on 4.1.1, and then flash CM12, or should I sequentially update each of the AT&T firmwares until I get up to 4.4.2?
Do official roms have the bootloaders and modems in them and install them automatically?
Should I use the Kies restore method?
The Canadian and att s3 phones are not the same model number. Don't flash an att bootloader to your Canadian phone as this may brick the phone.
Flash latest stock rom from Sammobile.com, flash twrp, flash cm.

Okay, but i can use AT&T roms tho?
The i747m will work with d2can, d2lte, and d2att Roms.
Is it safe to flash straight from 4.1.1 to 4.4.2 using a sammobile rom? will i brick due to Knox bootloader and modem?
Can I flash it using TWRP?
If someone could link a tutorial that would be very helpful.
I keep reading stuff that says to flash the newer bootloader before flashing a 4.3 firmware, and some that say the opposite. Others say that people should incrementally update.
I want to go from 4.1.1 original with Root and TWRP, to CM13.
Thank you.
Yes, you can flash the latest stock 4.4.2 rom from Sammobile.com directly to your phone. No need to do anything other than backing up your data.

Now I just need to get the balls again to use odin. Flashing the custom recovery using the Universal Tool Kit that had step by step walkthrough was adrenaline rush enough LOL.
I could also use Kies, as that has 4.4.2 OB3 (telus), and also has "emergency firmware recovery" feature if a brick ever happens. Though ideally the only time boot.img gets flashed is only with Full Stock Firmware files.
I find kies to be unreliable when I have tried to restore firmware so I always stuck with Odin.
I was on one of the latest versions of MM, I was trying to downgrade to 5.1.1. When i tried flashing the 5.1.1 it put me in a fail that i cant get back to 6.0.1. The only .tar i could get to flash is the combination flash that is for troubleshooting all sensors and hardware, I cant get twrp, or any other stock 6.0.1 images to flash back on it without fail on Odin 3.12.3. If anyone has any ideas how to proceed from this purgatory much appreciated.
It's back!
After being very persistent with not being able to flash anything but the combination firmware stock binary, I switched to usb port on back of computer, went backward to Odin 3.9.?, flashed an early MM firmware successfully with the help of a Pit file being flashed with stock firmware. Had recurring fails saying ext4 fail. PIT file fixed that. Back to square 1 now. Was on the latest MM,now on Jun 2016 release of MM. Still hoping to unlock bl and root .

If your bootloader is locked again I think you're going to have to Odin back to BPA1 and do the bootloader unlock process twice again to get back to MM with unlocked bootloader. What's your bootloader now?
Bootloader Is locked, will try to get back to the 5.1.1 again. Thanks
Hi Sir,
Can I flash stock firmware from 910F European version (GSM) after unlocking bootloader on 910V (CDMA)? Or I need permanent root or TWRP.
Because I just want to convert it to GSM phone but full stock without any customise.
Both versions have same hardware.
Please anyone help me. Is it safe conversion?
