[Q] Modem and Carrier Unlock problems with a foreign i9305 - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi, I had a P990 (who is simply un-brickable), so I'm comfortable with CWM, I ask to a friend who was passing by France to buy a i9305 for me, he bought one in SFR France, and delivered to me in Brazil.
Neither I or he knows if the phone has some type of carrier lock or something like that, the ROM is full of bloatware from SFR, I make the update on the phone over wi-fi (think it's called FOTA update, right) and now I'm on JB 4.1.2 version.
With *#1234# command, the info that shows is:
AP: I9305XXBMB4
CP: I9305AEBMB1
CSC: I9305SFRBMB1
Other info that could help:
Build Number: JZO54K.I9305XXBMB4
My problem is that trying to use my carrier in Brazil (VIVO), the phone has a very poor signal, it even sometimes in the signal strength at notification bar puts a Ø in place of the signal.
Other think that bugs me, is that in About device > Status, the field "My phone number" shows Unknown.
When I get the Ø in notification bar, if I go to About device > Status, the field "Service state" shows Disconnected, even if Signal Strength has more than 7 asu (think 7 asu is the minimum to get signal, right?)
So, my questions are:
1) Do I need to flash other ROM, CSC or modem, to get a good service in Brazil? Because phone is 100% stock from SFR France.
2) How can I know if the phone is carrier locked or something like that? If I flash a custom ROM, (like rXTREME) it will unlock carrier for me?
I have already make a backup of my IMEI using the tutorial in the DEV Section of our phone HERE and got the 250KB file.
Thanks for helping me =)

Flash modem and c|Sc for your carrier .
2) How can I know if the phone is carrier locked or something like that?
Ni network on any other sim .
If I flash a custom ROM, (like rXTREME) it will unlock carrier for me?
NO

Ok, but I go to SamMobile to get a firmware for my country (Brazil) and no GT-9305 firmware was for Brazil, only GT-9305T.
I find that the only difference is the 4G signal that the international version has more bands (800/1800/2600) than the GT-9305T (1800/2600).
My new questions are:
1) What's the differences from GT-9305 and GT-9305T?
2) Can I flash a CSC and Modem of a GT-9305T on my GT-9305 (without T)? It will not brick my phone?

Nice question i was wondering that too if it was possible to do so ?!
Thx

[Q] Flashing a 6603 (intl generic) FW on a Bell (6616) device?

Hello
I am wondering if its possible (and if so, if it works!) to flash a generic firmware on a Bell branded device (customization number 6616).
Thanks!
its possible to put a unbranded rom on a carrier branded xperia phone , without root i think it gets a little messy but it is possible... with root it should be easier
I'm looking for a workable reverse solution. I have an unlockable 6603. Can I flash 6606/6616 radio baseband and get LTE coverage on T-Mobile or AT&T when in the US?

So are you having any problems? You can use different PDA(rom) and CSC(sales code) as long as they are from the same android version. It shouldn't matter otherwise. The baseband version will affect your reception and is region specific(ie. What may work well in one region may not work so well in another) If you want stock samsung firmware, the version you install will replace the PDA, CSC and baseband that you have now.

hey thnx for the reply ..
ahan i see ok hmm i sought of got u but still the doubt remains the same which regions firmware should i download now?
My baseband and IMEI denote germany (unlike my CSC which denotes ireland) so should i download the kikkat version for germany or ireland? i reside in UAE so getting firmware of Germany/ireland that wouldnt be an issue ryt?( as i already mentioned the firmware presently in the phone isnt of UAE either n is either of germany or ireland ... so i know geting of a new firmware of these countries shouldnt ceate an issue bt just want to be on the safe side so i am asking u)

So I'm assuming you really want official firmware. I would suggest a custom rom but it's your choice. I don't think installing 4.4.4 official firmware will be a problem, only with the baseband as I mentioned earlier might be a bit hit or miss as it will be chosen for the region where it was released. Also once you install 4.4.4 I'm pretty sure you won't be able to go back to 4.3. The only thing I can suggest if you are certain you want official is try one, then if you face any reception problems or excessive battery drain or something try another one. You are not limited to Germany/Ireland either: By flashing the firmware you download, you replace the PDA, CSC and baseband.

Firstly ya i want the official one coz want to get back my warranty.i know i can unroot to get the warranty back but still i rooted it for being able to get the official fimware on my wish .. but i will surely check with the baseband thing n confirm whether the one i choose will work well i m my region(ie UAE) or not as u said its region specific( that is what u want me to do ryt before proceeding with a baseband Just being sure ..its my first time so want to be clear mate
The question of not being able to go back to 4.3 has confused me like i was willing to back up my current rom so anything as u mentioned arises, i would easily downgrade ! ?
Lastly i am downloading the offical kikkat (from samsung updates.com) so should i back my efs folder and imei as well?any help with that would be gr8

As I've mentioned before when you flash the firmware, everything is included such as baseband
Regarding downgrade from 4.4.4 to 4.3, I have read reports saying the bootloader won't allow you to install 4.3 as it is not compatible, but I'm not sure, I've never tried it. Just google and read as much as you can if this is important(being able to downgrade)
Always have a backup of efs folder on your pc. This contains important stuff such as imei.

Hi, I have a question. Recently my phone was updated to latest software 7.1 however i wish to return to marshmallow. This firmware that u have available, will it work for my country Trinidad and Tobago? What are the implications for installing a firmware not meant for your country? Also just for confirmation. The firmware software that I am finding does not match my PDA and CSC number.. Will this be a problem?

Question Changing service provider software version

How can this be done? I'd like the stock UK one (BTU service provider I believe?) as currently it's showing as VOD/VOD EUX etc.
Will my data be wiped? Is it really worth changing and going through the hassle? I've always had stock firmwares either out the box or flashed on Odin by myself but this time it didn't remove the carrier stuff.
I did initially flash the latest stock BTU firmware (all 4 files including CSC not home CSC), yet was still met with the carrier apps and the service provider info says VOD, I'm on Three the phone is unlocked but from Vodafone
