I bought an unlocked AT&T i747 in the U.S. and gave it to my sister in Germany, where she uses it on the O2 network. It's still on the 4.1.x AT&T stock ROM, and I want to upgrade it to 4.3, but have a few question for you S III experts:
1) Should I use the official AT&T MJB ROM, or one of the Rogers/Bell/Telus MK5 ROMs? (keep in mind that I need none of the carrier specific stuff, I just want the best 4.3 stock ROM for the i747)
2) It is unclear to me what difference the new 4.3 bootloader makes. Do I need o flash it, or am I better off leaving the bootloader unchanged? I understand one cannot go back once on the 4.3 bootloader, but I don't understand what advantages the new bootloader brings.
Any advice is greatly appreciated. I am still in Germany for a few days before returning to the U.S., and would love to perform the upgrade while I'm here.
Also, battery life is of utmost importance, so if upgrading to 4.3 is known to have any negative impact in this regard, please let me know.
Thanks!

Hi all,
I have a Galaxy S3 already and have been following this forum for a while, but I have never had problems with it as with this one. It's about my Galaxy S4 mini DUOS (i9192). I've bough the phone from an unofficial seller because i9192 was never supposed to be imported in Croatia (EU). The phone came with I9192XXUAMF7 build and modem. Today I've expereinced that the phone was running fine but I couldn't make any calls and nobody could call me untill I've taken out the battery and SIM. It was runnign on one SIM only. Network was OK and signal was full. I' would like to change the modem to see if that's the problem.
My question is - has anyone experienced anything similar or has changed the XXUAMF7 modem? I'm located in Croatia (Europe) and the closest country modem localisation is Ukraine. Should I change it to Ukraine modem?

Thanks for the notice! I have SGS 3 and it has no Knox bootloaders so I'm not familiar with it but from what I've read it's a no no. My original bootloader is stock Samsung. No Knox icons in download mode. I just might try your ROM. Have been reading about it just a few minutes ago.
I've been listing sammobile FWs and it gives me Russian and Ukrainian ROMs. You're suggesting I give one of them "a spin"?

Hi guys,i am the owner of a Galaxy s4 Mini I9195(i don't think i have the Lte option) but i don't know wich update is for 4.4.2 and for this phone.It's bought in Romania and unlocked and the BB is I9195XXUBML4 .My question is,wich stock Rom is for me because software update shows i have up to date firmware?And if i flash it will my phone get locked on that specific carrier again?
You can flash any 4.4.2 firmware with odin
But if i flash any stock Rom from my country with Odin,won't my phone get carrier locked or something?Atm it's unlocked but i'm a bit too scared.
I live in Canada and have a N975W and want to flash the star wars U1 firmware, but before I do I wanna know what happens when you put a Canadian Carrier sim in?!? Will the U1 CSC have Canadian Carrier info preset? Will I have to manually modify to get things like MMS to work? Or does the U1 firmware have Canadian stuff preloaded that gets triggered with the Sim card?
Thanks
Nobody?
Exynos

Now from the first just remember to do that whith already inserted sim into your phone so it can instantly fetch the settings of your sim carrier .

The American CSC does not contain information for Canadian carriers. After you flash the American U1 firmware, flash the Canadian CSC. There is only one CSC for Canada, and it contains information for all the Canadian carriers (Bell, Rogers, Telus, etc.). After flashing the Canadian CSC, when you insert a SIM from a Canadian carrier it applies the settings for your carrier's VoLTE, wi-fi calling, APN, etc.
If you flash Canadian CSC after flashing full U1 firmware will it not effect the U1 firmware? The CSC file is so large I'm wondering how it will effect the U1 firmware. Anyone do this yet? Do I need to use modified Odin?
Have you done this? Does flashing a different CSC effect the firmware?
---------- Post added at 11:58 AM ---------- Previous post was at 11:57 AM ----------
I would appreciate any input from someone who has tried this please. I really want to flash the star wars Android 10 for U1 on my 975W but am afraid that CSC will be different and not sure If flashing CSC from a different firmware will work as the file is so big.
if it doesnt work, you just flash back to stock firmware and csc.
just make sure its for the same processor.
OK, so, I flashed first Star Wars Android 9 version of U1 firmware to test and it works perfectly. Booted up with Canadian carrier sim and it loaded all APN settings. Everything works perfectly.
Flashed Android 10 version of Star Wars U1 firmware and its all good.
So you can load U1 firmware on N975W unlocked version. Same hardware and works in both countries. Do not even need Canadian CSC.
Do not load the HOME CSC file. It will wipe everything but its worth it. Firmware is solid and beautiful.
By flashing unlocked firmware, did you get rid of any carrier bloatware?
Can I ask you guys an info? I own N975u1, on first boot It haven't Greek language and I choose it later at setting. Does N975w on first boot has Greek language? So I install N975w firmware to solve my problem?(some settings remains in English).
975W is Canadian model and i have it on my note 10+ with carrier esk or eastlink if you wish to know what carrier esk stands for. If you are trying to get your phone to show Greek language I do not believe the 975w firmware would be a good choice. It lets you select which country you are from when you start up a freshly formatted phone but I have never selected any language other than Canada which is English. Just thought I would let you know that my model is also a Snapdragon chipset and I don't know if you can Flash another firmware unless you unlock Bootloader and I do not know if that is possible currently on a Snapdragon chipset Note 10.

I have n975w snapdragon with Virgin mobile. I can't access my oem unlock. Is there a firmware I can flash that will give me access while maintaining my plan with virgin?

The only phones with an unlockable bootloader are the N9750 (chineese variant) and Exynos models.
Can you please be more specific with what you are looking for within regards to firmware. Other then the information/answers posted in the first page of this thread I saw this thread, but depending on what your looking for specifically the post may not be of any help.
Also be aware that if you want to retain full compatibility with Virgin then you shouldn't go messing around with the firmware. Flashing other firmware (especially for US models) can result in things not working the way they would normally.

OK, so only the exynos version of my phone is oem unlockable? I am just trying to be able to root my phone, i figured if I could flash an oem unlocked firmware while keeping my carrier then I would be able to do so.

Correct.
Only the models with the exynos chipset and the N9750 variant can be rooted.

Only firmware for OEM UNLOCK switch in developer menu is exynos models. I found other sites on the net stating SM-N975W Snapdragon can be bootloader unlocked but i tried them all and none worked. DO NOT flash exynos firmware on Snapdragon model as you may ruin your phone or void warranty. Luckily mine still shows official and knox counter didn't get tripped. Sorry, wish I had better news 4 ya.

Bought a phone in US G988U but I am canada and need a firmware like G988W for Canadian BMC carrier
Is there a compatibility issue to do it?
https://samfw.com/firmware/SM-G988W/BMC/G988WVLU1BTI8
