as stated in title.
is it Possible to flash i747 ATT ROM to i747M BELL Hardware?
Things i have tried...
Mobile Odin, flashing Kernal/System/Cache of ATT Rom to i747M.
No boot Stuck at Samsung Galaxy Logo.
Tried to unlock Bootloader to flash Stock ATT odin. (Bad Idea)
used EZunlock and bricked my device. brought back with SDcard img.
any thoughts on the subject.
Although the i747 and i747m are identical according to many posts, I don't think they will work properly when using cross-flashed bootloaders.

I unlock both my Koodo SGH-I747M by following the instructions (just by punching a bunch of codes) from one of those YT video and I've been using T-Mobile's prepaid service since.

Since the specs are all the same for SGH-I747M (AT&T/Telus/Bells/Koodo/Rogers) + my phones are unlock, does that mean I can flash both my phones with Kit-Kat (once released) by any of these carriers (AT&T/Telus/Bells/Koodo/Rogers)?
Thanks.
p/s currently still on the original 4.1.1
I would not do it as att and koodo use different bootloaders and modems.

Glad I asked first, thanks for the reply and it makes sense :good:.
Personally, I would avoid knox as most custom KK ROMs will work fine with the 4.1.2 bootloader. I would only upgrade the bootloader if it was required for a ROM I really wanted to use.
Your unlock means nothing to the ability to install a ROM or not.
Now, you can install the Samsung ported Sprint Kitkat ROM for AT&T if you update your bootloader and modem to the MK5 version and never use ODIN or try to downgrade your bootloader ever again ! This ROM will not work without the MK5 bootloader and modem. If you proceed that way, your warranty will be void
Also, you can always flash Koodo builds
If you wish to keep your current bootloader, you can always install any of the non samsung ROMs, but some will require that you have the MF1 bootloader at the least (CM for example).
I've been serching for an answer for a while and can't seem to find a proper one that makes sure that I won't brick my phone. I've been flashing roms since 2011 and know pretty much the drill but lately I've been flashing at a couple months interval CM11 m builds and since I don't follow the threads like I used to, I feel like I'm missing out on how to do the right procedure.
So this is my phone:
Rogers i747 SG3
Cm11 4.4.4
Bootloader: I747MVLUEMK5
Baseband: I747MUMUEND3
I've installed these about a month and a half ago and since I've lost LTE networking but I didn't care to try to fix since I don't use it that much and left it like that.
This morning, I tried flashing MJB bootloader and modem zip in recovery but it gives me the classic error 7
Any Idea how to get out of this impasse? I've been searching all morning and can't find what I'm looking for...
I see you're in Montreal. Do you have the AT&T version of the s3; i.e. i747?
Your bootloader (MJB - 4.3 AT&T) and modem (ND3 - Telcel) appear to be mismatched. Maybe this is causing the loss of LTE connections.
What recovery are you using? Is it up to date?

I use Clockworkmod recovery 6.0.4.7 The latest version and Its an at&t i747 phone but with Rogers(same thing).
Is there other basebands or bootloaders I can maybe update with?
Sorry, I made a mistake. Your bootloader matches the modem for am i747m from here: http://forum.xda-developers.com/showthread.php?t=1831898
Boot into download mode and look at the model number at the top.
Cool yeah it is a i747m you're right.
Once I install the latest (canadian) firmware, does that give me the possibility to flash mjb and the Ne4 to have access to the latest cm roms without any trouble? Not sure if i understand everything here...
Do not flash any firmware not specifically designed for the i747m. The mjb bootloader is for the i747 and flashing that on your phone would probably brick it.

Well thanks for the link. I updated my firmware and played with the apn and now the LTE works again and hitting an 80 mb download... pretty crazy.
So are you saying that a i747m would not be able to flash cm12(lollipop) which states in the nightly thread that it needs a NE4 bootloader/modem?!
You can determine which bootloaders are supported by CM12 by downloading CM12 and looking at the updater script in Notepad. The first few lines will list the supported bootloaders.
The latest stock firmware for the i747m can be found at sammobile.com. This firmware is flashable in Odin and would include the bootloader, modem, and the dreaded Knox.
When I first rooted my S3 I was looking for ROMs to try. I remember coming across a link to download the stock Rogers ROM with the bloatware removed.
For the life of me I am not able to find it again now that I would like to go back to the stock ROM. Does anyone know of a stock Rogers Canada ROM for the S3 (i747)?
Thanks,

Depending on your bootloader, you may not be able to flash a de-bloated ROM if the de-bloated ROM flashes an older bootloader.
The boot loader is I747UCUEMJB
Do you have an i747 or i747m? Only the i747 (at&t version) has an mjb bootloader and flashing a Rogers ROM onto an i747 may or may not work well.
Ive unrooted my phone via the super user app but I still have the Liquid Smooth ROM. From everything I read I was under the impression it would reboot completely stock
How do get it back to stock ROM!? I have been searching everywhere and nothing?
I want to get my OTA updates as I haven't used this phone since last year. I don't have access to a computer as NY charger bit the dust and I'm working the next 2 weeks in a remote location with no WiFi (I have data though)
Can any on help me, I'm slightly desperate as this Liquid Smooth ROM lags horrible, reboots if I try to use the front camera (in any app!) and is missing a lot of simple stock features like the messaging app lol,
Oy what have I done am I stuck with this or is there a way to reroot without a PC so I can flash a stock ROM?!
I'm assuming you have the i747 from AT&T.
Unrooting simply removes your administrator access to system files and apps that need root access to be fully functional, that's all.
What bootloader is on your phone? If the phone has a 4.1.2 bootloader or lower, the easiest way to get back to stock would be to flash a stock AT&T ROM from sammobile. com using Odin and I recommend living with the phone in its current state until your get access to a PC and charger.
If your bootloader is 4.3 or higher, you cannot flash a stock AT&T ROM using Odin because AT&T naver released a full ROM that can be flashed that way. You'll confirm your bootloader and follow the appropriate thread to get as close to stock as possible.
I keep mentioning the bootloader because flashing the wrong bootloader/modem combination could hard brick your phone.

I attached an image does that help as far as boot loader goes? I'm not sure how to check it. I have the I747M on virgin mobile Canada. Att ROMs have usually worked perfectly. So if my boot loader is compatible I can flash a stock ROM with Odin without rerooting?
Since you have an i747m, the safest and easiest way to restore to completely stock would be to wait until you can flash a stock 4.3 ROM via Odin. Do not attempt to flash anything older than 4.3.
Custom AT&T ROMs will work on your i747m but I don't recommend using stock AT&T ROMs on an i747m. Also, do not flash AT&T modems or bootloaders onto an i747m as this will probably brick your phone.

Okay that first part sounds simple enough for me.
But what would be a preferable stock ROM to flash if not ATT (assuming you say this because my phone is Virgin Mobile Canada) If I remember correctly I had flashed a ATT stock ROM a long time ago and ended up with no service and security issues that I eventually fixed but were a pain in the arse to figure out. I don't know if I've ever come across a Virgin Mobile ROM. I believe they are a sub company of Bell btw.
Go to sammobile.com and flash any mk5 firmware you want for the i747m. You can choose from Rogers, Bell, and Telus.
I have cross-flashed a Rogers ROM onto a Telus Phone and a Telus ROM onto a Bell phone.
Based on my own experience, all i747m ROMs for Canadian carriers appear to be the same except for carrier customisations.

Okay! Perfect this is a lot more straight forward than I anticipated, thank you SO much!!
When flashing the ROM with Odin, uncheck everything except f.reset time. When the flash is complete, you will see the word "reset" in the status window. When you see reset, remove the USB cable, remove the battery, replace the battery, boot into recovery, and wipe cache, data, Dalvik, and reboot.
I have a Samsung S3 AT&T version, SGH-i747. The phone is rooted and I have the ROM backed up using CWM.
Can I flash this phone with the stock T-Mobile ROM version without any issues (I believe it is T999?).
My goal is to get wifi calling which doesn't come with the ATT model and from what I've read, if I can install the T-Mobile stock ROM or a custom version of it, it will come the wifi calling capability.
Thanks
Hi,
According to my experience, I would say NO.
But you can try it. And if it doent work, revert back to your ROM
By the way I am using custom ROM too on ATT phone.
It may be a matter of semantics, but do not install the stock T-mobile rom. Stock implies you will also be flashing the bootloader and modem. Installing the T999 bootloader and modem on the i747 will brick it. Anything from Sammobile would flash bootloader and modem.
Now, I have seen a number of CM, AOSP, and custom TouchWiz (based on Stock Samsung) ROMs for the i747 that will run on the T999. I would think the reverse would hold true, the T999 ROMs running on the i747. AS LONG AS they do not flash bootloader and modem. BE ADVISED, I have not searched the T999 threads to verify this conjecture. Some doubt enters my mind as I recall that T999 ROMs support AWS while i747 ROMs do not, this may break running them on the i747.
The T999 roms should run fine for the most part. It's safe to flash one to try, just DO NOT flash the firmware as mentioned above.
As for WiFi calling, don't get your hopes up. If I'm not mistaken it's tied into the modem (part of the firmware you cannot flash). So unless you have a T999, WiFi calling won't work.
