Hi guys,
Sorry guys for what might appear to be a noob question, but is there any major differences between the I9300 and I9300T model? and more importantly, will I9300 ROMs work on a I9300T model S3? or is the difference so minor that it won't really matter?
I have only just noticed that my model had the T. If someone could clear that up or shed some light on the matter, it would be greatly appreciated
Thanks in advance
I flashed it with the I9300 Italian latest rom with no issues at all. So I think they are the same, I think the network locked ones come with T, I got mine unlocked at the store where I bought it. It was Vodafone stock.

I'm guessing there must be some hardware difference. A different model number usually (always I think) indicates some hardware difference. Just adding a letter though, is usually the smallest difference of all.
The i9300 is capable of being locked, or at least it would seem to be considering it has menu functions for it. Could be wrong on this though, maybe it can't.
The T model is tuned to favour the 850mhz band. There is a difference in hardware but very minor. Other than that they are the same.
Just Google i9100 i9100t (S2 model) and you will find alot of info. Something about different sar value.
Anyway, as for flashing you'll have no problems. Firmwares are interchangeable. Same with the S2 but on the S2, it was better to flash a T modem afterwards for optimum reception.

I'm really curious about this coming from a gti9100T to a gti9300T I have found zero difference in using Tmodems vs any other

Oh ok. The only reason I ask is because I was on Sammobile and noticed this warning which stated "Do not flash I9300T roms with your GT-I9300 device!" so was wondering if firmwares were truely interchangeable.
I've been on Slim ICS on my I9000 for a while and was looking forward to flashing it on my S3, but was unsure if it would be compatible. I've tried asking in the thread but haven't got a response and thought that mayb someone else in the community could just confirm this for me.
but also from the little reading I've done, it appears that I can flash any I9300 custom ROM on my T model S3 and will just need to flash a T modem later. If someone could just confirm this, it would make my decision to flash a custom ROM a lot easier
Thanks

The T model of the S2 had a chip in line where the non-T model had just straight through wires. I was speculated that this was some sort of band filter that attenuated the non-850Mhz bands to favour the 850MHz range.
From experience I can say that, on Telstra, the S2 T model occasionally had crap reception where a non-T model right nex to it was fine. I believe this was in areas where the Telstra 850MHz network was unavailable and it was using on of their 2100MHz towers. Eventually, afer a lot of troubleshooting and flashing different ROMs and modems, I sold the T and got the non-T model.
I would NOT under ANY circumstances get another T model unless one of these useless clowns (Samsung, Telstra, Vodafone and the likes) actually tells me in writing what the difference is.
I did a hardware comparison with my friends GS3.
He has the I9300 and I have the I9300T.
Once both phones were flashed to the same ROM (Vodafone New Zealand) using ODIN, the only difference I could find (including the hardware that were listed) was the bootloader.
I just used first 3 apps I could find when I searched "hardware info" in the Google Play Store.
They all gave me the same results saying that the only difference was the bootloader.
Also we are both on the same network (2Degrees) which uses 900Mhz.
I have yet to have a close look at attenuation to see if there is any real difference though.

oh ok, that's quite interesting. I'm not very familiar with bootloaders (it was never an issue on the I9000 for me and so don't have much experience with it), but when you say the difference was the bootloader, what do you mean exactly?
you mentioned that you both FLASHED to the same ROM (Vodafone NZ), was that through ODIN or through CWM? As I've mentioned in the OP, my main concern is whether or not I am able to flash a I9300 ROM on my I9300T S3.
I'm no rush atm, as I'm waiting for a stock Aus VAU firmware to be released as a precautionary measure before I start getting into the custom ROMS, but just wanted to know so I can start researching which ROMs to flash once I'm ready
If you could confirm whether your I9300T model was able to flash a regular I9300 custom ROM, it would be greatly appreciated. Also, if you've got any recommendations as to which ROMs are good, that would be helpful too.
Cheers

yeah I ordered mine online and didn't realise it was going to be a T model S3. If I had known, It would have most likely affected my decision to purchase the phone. From my experience on the I9000, it's always so much easier to have the full international version (more compatible ROMs, more options, more support etc) and having any variants (not sure how much of a variant the T model is) is always abit more troublesome
I'm just hoping that the I9300T is compatible with the vast majority of custom ROMs out there for the I9300, otherwise I'll be hating life for the next 2 years
you mentioned that you both FLASHED to the same ROM (Vodafone NZ), was that through ODIN or through CWM?
If you read on, just after I say that, I say "using ODIN", so yes I did it through ODIN.
If you could confirm whether your I9300T model was able to flash a regular I9300 custom ROM
Yes, I9300 ROM's can be flashed on to the I9300T. They use the same hardware AFAIK.
The only thing you need to worry about is flashing the right modem, but if your network uses the standard 900Mhz band, then you'll be right.
When I got mine they didn't tell me it was the T model, but after flashing a stock ROM instead of the branded ROM, it was fine and I didn't notice any problems.
All you need to do is flash a I9300 stock ROM then flash CF-root using ODIN to root the phone, then you can use CWM to put any ROM you want on the phone.
EDIT:
A bootloader is basically the stuff that interfaces with your hardware right at the start.
You should never touch this because if you screw up your bootloader then you can kiss your phone goodbye.
Flashing custom ROM's is safe because they never touch the bootloader, thats an entirely different procedure using ODIN.
The only reason I want to touch the bootloader is because I want to know the difference between the I9300 bootloader and the I9300T bootloader.

Sorry, I must have missed the fact that you mentioned you used ODIN, but thanks for confirming again.
I've done some reading through XDA already and I've gathered that some people have been flashing regular I9300 ROMs on a T model S3, but that's only through looking at their sig, which may or may not always be up-to-date, so again, thanks for confirming that too
It also appears some people using the T model have been using the regular modem, and with better results too. I'll probably try experimenting between the 2 variations of the modem and finding the best fit for myself
I think Chainfire's CF-Root is compatible for both I9300 and I9300T models, so I should be ok to root and just get straight into the custom ROMs without flashing a stock I9300 first
and thanks for that brief bootloader explanation. seems like if I get CF-Root running, I should be good to go with the custom ROMs so won't look into it too much, but it's good to have a better understanding of it.
Many thanks for all your help so far

Ok. Let me explain what I've noticed and hopefully clear things up.
I had the S1 non T and flashed the guts out of it.
Then got a T model S2. Running Optus sim. Got poor reception when I flashed an international rom + modem. Turned out all I had to do was flash a T modem anytime I flashed any custom or i9100 rom. But, as mentioned I could flash anything I wanted.
Now, I have a T model S3 with the same setup, and thought it would be like the S2. Turns out that it doesn't require a T modem for good reception. I use the lf5 modem and its just as good if not better than the T modems I've tried.
So, for the S3 flash any rom you want. If it does suffer poor reception there are plenty of T modems available in xda in cwm and Odin format. But don't think you'll need to.

Thanks for clearing that up. I didn't upgrade to the S2 so was not familiar (or even aware) of there being a T variant. As such, was not sure how much of an impact that would have when flashing roms. I just knew that a lot of people had issues when flashing the I9000 roms on a variant of the S1.
But now that I know that any S3 custom rom should run fine on my T model S3, I'll start flashing once a stock AUS VAU firmware has been released (in case anything happens). I'm also using this time to see if there are any hardware faults with my device, rather than running a custom rom and finding an issue, and not be sure if it was there with the stock firmware or not.
And again, many thanks for clearing that up. I can now start searching through XDA for roms (that appear stable) and then flash once that stock firmware is released

No problem.
Earlier I saw a thread where a Vodafone Aus firmware had been added. It was in cwm format so all that needs to be done is flash and unroot + clear counter. Phone would then be stock.

Yes, I have an NZ I9300T and the Vodafone NZ ROM works fine when you flash (install as you say) it with ODIN.
Thanks for your fast reply mate!
One more question. I have rooted my phone, do I just download the NZ vodafone Rom, and flash it using Odin? That simple?
Sorry if I seem stupid lol. New to android after 3 years of Apple.
Again thank you for your help
Note: I have already download the rom was approximately 750mb in size.

I've searched a while through the forum to find an answer to my question. Maybe someone can point me to the correct thread, if my question was already asked.
Last week i have flashed my S3 with Omega Rom 12 and the phone works very well. There are no problems at all but i'm curious about the CSC topic. The Rom has CSC EUR (CSC: BLF1 - set be default to EUR), also *#272*<your phone IMEI># says "EUR" (which stand for Greece, afaik). But i'm using my phone in Germany in the BASE/E-PLUS network, APN entries are correct, Internet, phone and sms does work. At starting the phone, all settings were right after selecting country and provider.
So, is it mandatory to use a CSC specific for Germany or is it save to stay at EUR?
~Eyghon
No its mandatory .......some time some custom rom is def CSC......
but if u found ur CSC install it.....

Moved to Q/A, the dev section is for development, not questions
NOT MANDATORY
CSC is not a requirement for the phone to work .
See the Guide on page one .
jje
Not mandatory but if you do not use the right CSC you will loose:
-right fast dormancy setting for your carrier
-HD voice activation if your carrier support it
Not a big deal for some people but could be important for others...
not mandatory as long as you run into some sort of problem, i have used my phone without any csc for months.
Thanks for your feedback. I assumed, that it is not mandatory, but i wasn't quite sure. My rom has a tool named Fast Dormancy built in and it shows, that FD is enabled, but how the settings are i have to find out. But till now, I have this phone just a week and everything works fine. Mainly using Wifi and GSM/EDGE. Next week i have 3G only again, will see, what happens.
Every new phone produces a lot of new questions until it is completely explored.
So for an I9300, i can flash any damn stock rom as long as i get my model number correct? I'm from Singapore and i can flash a rom from Jamaica?
it's only mandatory if you want to receive and OTA or update through KIES, if your using ODIN and or CWM to flash roms then you never really have to worry about CSC's.
I9300 rom on any i9300
Modems interchangable .kernels interchangable .
The key word is International .

There was some confusion over what a CSC Code is and what happens to it when you flash a ROM.
CSC is the Consumer Software Customization and is specific to geographical region and carriers.
It contains the software packages specific to that region, carrier branding and also APN settings for data connection, MMS etc for your service provider.
CSC has nothing to do with what languages the firmware supports and it will not add keyboard language support.
CSC does not affect what firmware you can flash and is frankly irrelevant half the time.
What Happens to your CSC when you flash a ROM?
If you flash a custom ROM (like HyperGalaxy) you will not be able to see your CSC code.
If you flash your nations Stock Firmware (like UK Stock ROM or US Cellular) you will get the default CSC Code used for the entire nations unbranded phones.
If you flash your nations carrier-branded Stock Firmware (Like T-Mobile UK or T-Mobile US) you will get the carrier specific CSC Code which can identify what ROM you are using.
If you have a branded phone, I recommend using your nation's unbranded counterpart to insure your stock has the most flexibility in terms of updates, then use TriangleAway to hide your flashes. THIS WILL VOID YOUR CARRIER WARRANTY BUT NOT YOUR SAMSUNG WARRANTY.
You can find your CSC Code by dialing: *#1234#
I hope this clarifies things for people.
One thing I have not been able to work out from searching is if the CSC will have any impact on the battery due to settings like Fast Dormancy?
Living and working in Germany I got my GS3 here and despite being shop bought unbranded it installs a load of German applications every time I have an update (Bild etc) and I got sick of disabling and deleting them each time. I flashed an older BTU firmware and then used Kies to update to the latest BTU (4.1.2) which has worked out fine, but I cant help feeling the battery life has diminished from this.
I've been flashing Android phones since the Galaxy S but believe certain things like the fast dormancy are newer and this leaves me wondering if the CSC now has more of an impact per region..
Any info please?

It could have something to do with the RIL (Radio Interface Layer)
https://play.google.com/store/apps/...t=W251bGwsMSwyLDEsImNvbS5zaWJib3IuZ2V0cmlsIl0.
Try that and install a matching RIL.

Huh, that shows me a mismatch. RIL is not something I am familiar with (and I try!) so this is interesting. I'm also very surprised Kies did not update the entire thing.
So I better look into what RIL entails overall. And consider that thanks button pressed.
Hey guys,
I've been doing some reading and trying to work out the best way to dump a copy of my CSC so that if I flash in a new custom rom from another country that has JB that I can then load in my original CSC to get the settings back.
I've seen this thread http://forum.xda-developers.com/showthread.php?t=1106502
But one of the first things it says to look for CSCFiles.txt doesn't exist on my S3.
Is there a better method for backing this up? Additionally would like to backup my modem just to be 100% sure so ran through another thread to backup the modem (http://forum.xda-developers.com/showthread.php?t=1705650) but the backup image came out significantly larger than the other modem files I have downloaded and the MD5 doesn't match what is supposedly the same version modem.
And one more question, I found some time ago a really good thread explaining the firmware versions as there is B firmware and C if I recall correctly and the relation of these to the modems and why flashing the wrong one can have issues. I haven't been able to locate that thread again to bookmark it, if anyone can point me in the direction of this it'd be awesome.
Beacuse there is none..all the Firmwares are more or less same with little region specific customizations..
You can flash any firmware if you are okay with the region specific changes..
There is no need to backup your modem you can get it easily from here..just note which modem you are using currently..
CSC again does not make much of a difference other then providing you with region specific customization and updates.....you dont need to back it up ..you can change you CSC using dialer or CSC changer from the market..

I understand I can flash any firmware, hence asking about the CSC's to be able to retain my regional customization's.
Modem was more a paranoia of making sure what I have is exactly what is available on here. E.g. pull it out MD5 and compare. I'd rather be sure and pull the modem out myself and confirm.
I had seen references to B type firmwares and about using specific modems with certain firmwares for compatibility.. Hence the question regarding this.
I've got the CSC changer but isn't that only able to change the CSC to the ones in that firmware? From looking at the firmware list in some of the reference threads that listed the CSC's they came with they didn't list my region.
Basically I want to know that when I flash in another firmware, in this case the 4.1.1 from the UK that I can load in the CSC and get the region specific customization's back and at the same time have a route back to the original modem and firmware that I have taken backups of myself.
With that all said the modem issue is sorted but still need to confirm I can migrate the CSC from my current firmware to the new.
