I previously upgraded my phone's firmware to 2.3.6, seeing that Bell Canada's stock firmware for the SGS2 is 2.3.3, and has never received an update since release. 2.3.6 is much better in many ways, however the problem I encountered was random network (3g/4g) disconnection, while always being able to make and receive calls and texts. Curious to know if there is a work around to this problem? If I were to take an educated guess, could the modem file of the rom be the cause of this problem? Seeing that my SGS2 is a i9100M model, and the firmware "changes" the phone's model to i9100. Furthermore causing the network to not recognize the phone's modem?
I really would like to be able to avoid this issue because I downgraded back to stock branded courrier firmware. 2.3.3 is hard on battery usage and touch response is much worse than 2.3.6.

You didn't have to downgrade. You just needed to find modems that are more compatible with your network. Modem thread here. (easily found with a google search for "xda modems galaxy s2"... it was the fourth or fifth result)

Yeah, I already looked at that thread, including the thread dedicated to Bell/virgin courier. So I guess you missed the point of my question. I did ask what I could do to work around the problem, afterwards taking an educated guess that the modem was the issue. Maybe this forum deals with a lot of people that don't use search, but lets not put everybody on the same boat. Thanx

No offense intended, but the wording of your question didn't lead me to believe you looked at that thread, and that you were just speculating at this point that it was an issue with your modem. Sorry.
But in answer to what you could do to work around the problem, if the modem currently flashed to your phone is not ideal to your network operator, there really is no work around other than to flash a modem that is better suited.
No worries, no offense taken, was just justifying myself. So, if I understand correctly, it is the possible to flash the rom without flashing the modem? I'm just thinking logically here, but I have flashed back to stock rom, hence my network issue was resolved. I downloaded the latest 2.3.6 firmware available, so instead of flashing the modem I can leave it blank?

Hm... I honestly don't know. Where'd you download the "latest 2.3.6 firmware available"? From Intratech's official firmware thread?
If so, those packages contain everything in the zip, including the modem. I think what you can do is open up the package, and remove "modem.bin", and zip it back up. That may leave the modem you currently have... But I don't know for sure, I've never tried it.
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.

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.

Hi guys I just wanted to know if what I'm about to do is the correct method to upgrade my firmware from gingerbread to ics.
I bought my phone ( i9100 ) from Hong Kong and I live in a different country. So when there was an update for its firmware, i was unable to receive it even after checking for updates through system. So what I'm about to do is use Odin and download a firmware from samfirmware under HK's firmware and put it in the PDA part of Odin and run it.
Is this method correct? Or am I suppose to do something else? My phone is not rooted and I dont intend for it to be just yet and I'm also wondering if I use HK's firmware, will it affect my network coverage? Because being in a different country and having a different assigned network and all might cause a few problems with its radio or something?
Please advice thanks
Hi yes that's how I upgraded my firmware that method will work. Be sure to factory reset first though. As for your carrier concerns I can't answer sorry. The beauty with this though is that you can re-flash a different firmware if it doesn't work. All the best

1. Your method is correct. You shouldn't have signal issues.
Before flashing you must go through the flashing guides.
2. If you are living in another country and don't have plans of going to Hong Kong or your phone is out of warranty (this doesn't matter), you can flash any firmware for your present location. It will work very fine.

Long story
I used Odin to flash Multipackage XXLH3 ROM for s5830i by Alucard1989pl
Since then I've had lots of issues with phone network.
For some reason my phone only connects to a network called EE.
Also when I search for available networks it doesn't show T-mobile.
Big thanks in advance for getting back to me. My GF is trying to kill me for messing her phone up. :crying:
try this one to see if sim can connect to T-Mobile...

For some reason Odin keeps giving me a "fail" when I try to flash that ROM.
@N8trix You're right. But still having network issues since flashing that CSC, PDA and PHONE.
Also somehow all 200 sim contacts were wiped.
Would just like to stock the phone. Kies firmware restore feature isnt working at all.
Sorry about the lack of detail right now. At work.
Are you sure you have S5830i. Maybe 5839i or a plain 5830. Or may be a different phone. Can you verify your model?
Do you want an empty life, or a meaningful death?
Hello, first to say I'm from Spain and I don't speak English very good, but I'll try to do my best.
I have a GT-I9100 with CyanogenMod 10.1 (Android 4.2.2), baseband I9100XXLS8 (when I instaled 4.1.2) and Orange Spain.
My problem is when I am using mobile data, full signal, my phone often doesn't connect to the internet. I talked with a friend and he told me that I have to research how to change my baseband to the best for my android version and mobile operator. Can you help me? Tell me how to do it? Wich baseband version to use and where to find it?
If you don't understand something or you need me to tell you some other data, just ask and I'll try to do it my best.
Thanks,
Efalgae.
Just search for veyka,and google what can go wrong with flashing anything.
Read about nand/efs backups/odin pc setup/cwm and mobile odin.
Or you can just do what most of the impatient/lazy clowns on here do and flash a modem and pray nothing goes wrong.
-------------------------------------------
maybe your an iphone expert
------------------------------------------
Now then, you could sit here & hope someone who uses your carrier reads your thread & suggests a modem to test, and that may or may not happen. You could spend ages doing Google/XDA searches trying to find a modem that works with your carrier, or you could do the following (And I assume you mean mobile data sometimes works, sometimes doesn't ?) which could solve your problem sooner rather than later:-
Go to Samfirmware, find the stock roms released by your carrier. Start with the most recent one. Work out which modem is bundled with that stock rom (It lists Product Code/PDA/CSC/MODEM for each firmware when you click the link), do an XDA or Google search for that modem, flash it with CWM & test it. If that doesn't improve your connectivity, try the modem bundled with the stock rom released before the most recent one, test. And so on until you find one that works. Hopefully the modem bundled with your carrier's most recently released stock rom works for you tho; you'd expect they'd test it to ensure it works for most people most of the time & in most places with their network.
Whatever you do, don't flash any RIL's unless you've tried every single modem (including those bundled with stock roms released by other carriers & even in other countries; there are dozens), only flash a RIL as a last resort.
If mobile data never works, check the APN settings in settings/wireless & networks/mobile networks/access point names Vs the APN settings on your carrier's website (Actually, double check these anyway even if you end up testing modems as above).
Thanks to all.
Because I have no patience, I decided to flash last official firmware released by Orange Spain, found in SamMobile.
I flashed it, flashed CWM again, and CM 10.1 again.
Seems to work perfectly.
Anyway, thanks again to yor answers
And...yes, my mobile data was workin sometimes and sometimes not.
