[Q] Downgrade firmware from Australian carrier Jellybean to UK ICS? - Galaxy S III Q&A, Help & Troubleshooting

Hi Guys
I'm a newbie here... I've done thorough searches here, but no-one's posted a query like I seem to have?!
I purchased an Australian SGS3 I9300 on the Optus network from the UK eBay site (this wasn't mentioned in the auction, so I expected to receive a full UK firmware/spec phone), it comes with Jellybean which I'm not a massive fan of...
Am I able to downgrade the australian 4.1.2 Jellybean firmware, to either an international or UK (O2 Telefonica) ICS 4.0 (which I love)?
Is it just a general download of the international firmware from Sammobile and flash through Odin?
Any help and advise appreciated

I would root the phone first and make a backup of your current firmware. Then just get the ICS FW you want to flash and do it through odin.

Thanks for your reply!
I was 'hoping' not to root it, and just do it as a general firmware download?

wouldn't you rather have a backup just in case though? you can always use triangle away and then once you flash with odin you will be back to stock anyway!

Get a copy of the firmware that is currently on the phone or at least make a note of it .
Then via Odin flash a stock UK rom from stock rom thread or from sammobile.com .

Thanks for your reply guys - very helpful
I'm going to make the backup and install the new (older) firmware

[Q] New S II. Bootloop after flashing theme

I got a new S2. Its GSM from Germany. I tried to flash an ICS Theme. But now i got bootloops. I tried to Wipe everything but it doesnt work. I am able to use Odin or Kies. Can somone help me to bring it back to where it was original. without any theme and no root? i got Odin and Kies installed. Where do i get Stock Rom for 1und1 Germany or Stock German rom and how do i install it?
which is the right firmware to download. i dont get it which one is the right one and which one is the newest to use for german language
i got these information from my rom XXKI4, KJ1
Get carrier-specific firmware here or if your carrier isn't listed in that thread get country-specific firmware here. You could also use Checkfus (do a search on here) to get the latest firmware available for your carrier that you'd normally get via Kies.
thanks a lot, but i dont know which one of the country specific is the newest and right one for me. Can you help me out?
Looks like there's only one available in Intratech's official carrier firmware thread for O2 Germany (XWKI1), Checkfus says KI8 is available for O2 Germany (Dated: 22/11/11) assuming you have a I9100 (check the sticker under your battery to make doubly sure.
I don't know which one is more recent as Intra's firmwares don't have dates on them, but I'm guessing the KI8 available thru Checkfus is more recent as this would also be available via Kies. I don't think it will make a great deal of difference which one you use at the end of the day given you don't seem to know which firmware you had on your phone originally. Either will work just fine with your phone I would imagine, provided you definitely have a I9100 or I9100T
Up to you which one you use.

[Q] No available update on kies (even though i should have!)

Hi all, I'm new to posting here but a vet over at samdroid.
I've looked around quite a bit and my problem seems to be unique...annoyingly.
I got my S2 on contract from O2 about 4 days ago, instantly went home and found out I was eligible to upgrade to ICS officially via kies. I have been on kies and connected my phone every day since, and I keep getting told I have the latest version (2.3.5), even though I've seen countless threads/comments of people delighted about the fact they upgraded through kies!
I was thinking of trying odin (i was a pro at updating roms on my spica), but don't know if using an offical update through odin instead of kies would void my warranty etc. NOTE: I don't want to actually root my phone (yet)
I hope that all made sense and any help would be much appreciated
Thanks,
Oli

make sure you got i9100 not any other varient
does other O2 in your area got ICS via KIES
odin is fine and will not void warrenty aslong you dont root and flash back the ROM you have now. you have to find this ROM first if you want to go back.

well o2 have officially released updates in the UK, if thats what you mean? will there be a thread on this forum with the offical ICS ROM or will i have to find it via google?
I got my S II on monday from o2 and I beleive its the I9100p not the I9100, if yours has NFC written on the back its the I9100p and for some reason there is no ICS on kies yet for it

what do you mean by this?
also is there an official rom for my particular S2 that can be updated using odin? or even an unofficial one that wont void warranty?
thanks for all the help guys
This Thread has instructions and official ICS.
Plz note that this is official and will have TouchWiz and does look extremely similar to Gingerbread and without root and custom theme you will not get that ICS feel. You will however get most of the goodies that ICS has to offer.
I got my S2 on contract from O2 about 4 days ago, instantly went home and found out I was eligible to upgrade to ICS officially via kies.
Well that's not exactly true you upgrade if their is an upgrade for your exact phone .
Kies has firmware for GT-i9100KAO2U product code .
I have been on kies and connected my phone every day since, and I keep getting told I have the latest version (2.3.5), even though I've seen countless threads/comments of people delighted about the fact they upgraded through kies!
But not for your phones product code which obviously does not match the released O2 firmware .O2 may well and probably over twelve months had more than one phone for sale unless contract has different codes to PAYG .
Standard older O2 UK firmware for xxx Product codes is on Kies its also on this forum in a legitimate flash via Odin .
http://forum.xda-developers.com/showthread.php?t=1544487
legitimate O2 firmware not stock Samsung tested and works on O2 .
Or you can go to Google find CHECKFUS and try to download from your codes .
jje
you still didnt confirm if you have i9100P which i think you have but i could'nt find the Stock ROM your running now, so you can go back to it later if required.
if you have i9100P this thread has good news for you though the actuall thread is stupid and useless...
http://forum.xda-developers.com/showthread.php?p=24030713
i think what happened to u is you got the model which is i9100P not the usuall i9100, thus all on normal model are on ICS and you still on GB. you can wait for it to come or use the i9100 ROM's but please search if that is actually possible.

i read somewhere that i can use i9100 firmwares on my i9100P, so which of those 2 links would you recommend? also, is there a lot of risk or is it pretty easy and you're just covering yourself?
finally, if i update like this, will i be able to update officially through kies when the update is finally released for me?
no im not covering my self...... i tell you in points....
1: you got I9100P on O2 for which i cant find a firmware for.
2: because you cant go back to your old firmware which is O2 you will get into warrenty problems

ok, i guess i'll wait for the official update then. thanks for your help
here are your options if you still want to continue.
1: you can flash stock firmware for i9100.
2: you can flash custom firmware
3: you can flash O2 branded firmware for i9100.
but in all cases NFC wont work by default.
plus now you cant go back to O2 i9100P firmware as it cannot be found anywhere... atleast by me.

CSC relevance

When I connect my S3 to Kies, it shows the following firmware : PDA:LH9 / PHONE:LH9 / CSC:LH9 (BTU) [Am running the JB leaks]
I bought my S3 internationally, so that is probably why the firmware is the UK version.
However, I live in India. So, my question is, when the official JB comes out, will I be able to update my S3 to that from Kies after removing root & resetting the Flash counter from Stock ROM ?? But will I also have to change the CSC code to India to be able to update from India or just flashing the Indian 4.0.4 firmware from Sammobile will be good enough. I don't really have much idea about CSC, so please forgive me if it's a stupid question.
Sorry, if this already been asked before, but I couldn't find any info upon searching.
Thanks
The CSC isn't relevant at all. You can go to http://sammobile.com or even http://androidfirmwares.net and look for the relevant Multi-CSC ROM. Now saying this is don't know what's the CSC code for your region if one exists but it won't make a difference what you flash because there's no differences.

Grab your stock Rom from sammobile original and why not new JB when it comes out for your exact provider. I'd flash it with mobile odin pro and keep everoot. Counter will be 0, status will be normal. Need warranty remove traces of root unroot and you're done.

[Q] How do I know what update to flash to from Sammobile?

I'm not new to this, been flashing roms since 2010. I'm running rooted ELK4 4.1.2. i want to flash the latest update from Samung, the official 4.1.2, yes I know I will lose root, I'm fine with that. I already did triangle away to prepare to go stock. Now, I bought the I9300 off amazon, so I know not of where it came from. How do I know what version of 4.1.2 to download from sammobile? Hope it's not a stupid question, because I looked for 2 days and couldn't find and answer.

I think you can flash whichever stock rom you want...why not?I mean you can flash custom ROMs with CSC ELLA without the stock ones being available in your country.The only issue which you have is unavailable OTA updates(with custom ROMs which is obvious )..So I think you should flash tha latest stock ROM available in YOUR country from sammobile.Anyway you can find s3's country by giving its IMEI number to your local samsung delegation.And you could ask them too in order to be sure.
there is no american stock rom for the I9300 on sammobile

You didnt mention you're from America..You can't find it cause I9300 is not available there I think.As I said before I think that you can flash wichever stock for I9300 model but I'm not sure so you can either wait for another answer or ask your local samsung delegation.

[Q] galaxy s3 software update international

Hi everyone, I got a international s3 or European I just know it's not from my carrier directly. My question is will I be getting software updates according to my carrier/country or will I be receiving the updates the time it comes out in Europe? I'm asking because I updated to 4.2.1 about 2 months earlier than my friend did and he bought it straight from Vodafone NZ
Official 4.2.1?
I think it depends on your Carrier
You will be getting updates when they come out in Europe. Updates are actually pushed through according to your phone CSC as you have an international unbranded phone unlike your friend's Vodafone branded unit.

Oh by the way, is there any difference to the software updates between countries apart from them being released at different times? I was on International UK rom but I flashed NZ stock rom and now its seems im having quite a bit of battery problems, just wondering so I know whther to reflash international stock or leave it with NZ

I found heaps of guides but they only guide on how to go back stock from a custom rom. Im already on stock rom though and i want to revert back to international stock rom but NZ stock.
Soz im a noob, still new to this
it is no different
So which is true? Does software updates follow the carrier the phone is using (eg. Vodafone) or the region (eg UK/EU)??
