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 live in Israel and I want to flash official israeli ics rom to my galaxy s2 i9100 ....is it possible?
No. You would brick the phone.
Sent from my Galaxy S2 GT i9100
But there's no hardware differences between this versions as I know only different modems so the 3g would work normally...so why should this brick my phone?
Australian/Oceania variants
GT-I9100T
The GT-I9100T (sold by Vodafone Australia and Telstra, and some carriers around the world except Europe and the Americas) is virtually identical to the I9100 and is functionally equivalent. There are claims on the XDA-Developers forum that this variant there are some differences in software, giving slightly better performance in the 850 MHz WCDMA band.

Info taken from wiki. In theory seems yes, but you don't have to. Your phone will work with any ROM designed for i9100.
Sorry about the wrong info. :/

YES, it is possible.
Do the following when flashing such Roms:
1. Backup your present ROM just incase.
2. Do normal wiping necessary before just like you want to flash a new ROM (just ask for help if you don't know what I'm talking about)
3. Flash the ROM
4. Flash back your modem (also known as baseband version)
5. Flash an I9100 custom kernel e.g Siyah or speedmod (don't flash any CF-ROOT kernel)
6. Fix permissions (under advanced)
7. Reboot your device.
All should go on as expected
Good luck

Hi guys, i want a firmware or custom rom for galaxy gt-i9100t, if there is any rom after 4.1.2 ! , also i have a question: the normal rom for g-ti9100 could be installed on gt-i9100t !!?
There isn't any stock firmware >4.1.2. Yes, you can flash I9100 stock roms on the I9100T, but you may have to use a modem from an I9100T rom if you're using the phone on a network belonging to a carrier who sold the I9100T.
okay 10x for help, i'm so greatfull
What about a i9100 custom rom?! Can i use it to i9100t !?
Sent from my GT-N7100 using xda premium
Yes, of course. the I9100 & I9100T (I also have an I9100T) are exactly the same except for a very slight difference in radio output, achieved by firmware - the modem.
If you flash an I9100 stock rom, it will include an I9100 modem which might (not always though) mess with your connectivity, and as I hinted at in my PP, in my experience, using modems which have been bundled with stock roms released by carriers which sold the I9100T tends to result in the best connectivity. You can check these by searching the I9100T firmwares on Samfirmware, which lists the baseband (modem), and you can then find/download whatever modem in question here.
However, if after flashing an I9100 stock rom your connectivity is OK, no need to change the modem. Only change the modem if your connectivity isn't great. Custom roms don't include modems, so flashing a custom rom won't change your current modem.
i got it, thank you very much for your help and your notes about the modem thing :good: .
