[Q] little help with downgrading firmware i9300 - Galaxy S III Q&A, Help & Troubleshooting

Hi guys i have busted last 2 phones because i didnt read enough or ask 1st, so im ere to ask a few things if thats ok, well i got a contract phone on 3 network in uk and have fully updated it to PDA:MC2 / PHONE:MC2 / CSC:MC2 (BTU) now i want to backup the original firmware and after reading have decided the best way to achieve this is with kies software. To do this i need to be on an older firmware after looking i think this is it
galaxy S 3 (International) GT-I9300 BTU I9300XXDLJ4 Android 4.1.1 is this the correct 1 for my device as i dont want to mess it up if im honest all i want to achieve is have it rooted with cwm on there and a backup is the method described the easiest way or is it easier just to root then install cwm then do a backup i am a bit clueless really dont wanna screw this phone up TIA

[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.

so which one there should i use? and can someone remind me if "flashing" just means updating (it's been ages since i used odin and stuff so i've forgotten a lot of the terms.)

these are i9100P europe firmwares.....

these are i9100 firmwares for O2....

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.

Flashing the New XXBLG6 ICS 4.0.4 Firmware / JUST RELEASED

Hey guys. I have the I9300 and my build number is IMM76D.I9300UBALF3 , and I just read that the UK is getting OTA update for XXBLG6 with some nice improvements. This website says that I can simply download their file and use ODIN to install it.
http://www.android.gs/update-samsung-galaxy-s3-i9300-to-official-xxblg6-ics-4-0-4-firmware/
My questions: will this infringe the warranty by any means?
Why does KIES not show that there is an update?
Is it possible that my phone will not be compatible with the update as it probably is not a UK model? ( dunno the difference )
Is there a chance that flashing the update will brick my s3, since I am not actually rooting or anything.
P.S. - I do not have root and I do not plan on getting it yet.
Thanks guys. I appreciate any help!
If u have the correct model number, u can try and it won't brick ur phone normally.
But it is at your own risk.

You would need to ask that web site bit stupid asking another forum for advice on another forums products .
Why does KIES not show that there is an update?
You do not have an update yet .
Is it possible that my phone will not be compatible with the update as it probably is not a UK model? ( dunno the difference )
Yes if its not I9300 International model .
Kies will not offer a UK update to a phone that is not a UK product code .
Is there a chance that flashing the update will brick my s3, since I am not actually rooting or anything.
Yes always possible .
P.S. - I do not have root and I do not plan on getting it yet.
As you do not know what phone you have you would have two choices .
One wait for whatever your phone is and Kies to update it .
Two you could join XDA Developers forum download the stock UK firmware and flash it on the day of release .
http://forum.xda-developers.com/showthread.php?t=1671969
The risk is very small but it is a small risk that gets much bigger if you do not follow the instructions .
Personally in your shoes i would start reading and understanding first .
PS not heard of these nice improvements ??

I do know what my phone is lol. It's the i9300 , just not sure if my firmware is a UK firmware or a different one. The improvements are on the stability, noise crackling sound, camera features, screen brightness easily accessible.
So since I know that I do have the international version I9300, can I update through ODIN without risk? or? Furthermore, will any build work for the I9300 no matter the location based firmware?

If your phone is not carrier bound you can flash any region as long as it is for your model.
Yes, there is always a risk using Odin. But then again Kies can jack your phone up too.
I put my faith into Odin. YMMV.

[Q] Rooted using toolkit 5.0,need help

Hello guys.
Samsung Galaxy S3 GT-I9300
I was wondering if anyone could answer a few questions for me. I rooted my new phone using the toolkit method from this thread http://forum.xda-developers.com/showthread.php?t=1703488 and now i am confused about the firmware versions,and if the kernel was changed and such. I forgot to check all these versions before i rooted the phone,so have no idea if these are the original ones.
My phone is bought and used in Denmark,however the firmware suggests it is now a uk version looking at the country code could this be correct? If i look at this http://www.sammobile.com/firmware/?page=3&model=GT-I9300&pcode=HTD&os=1&type=1#firmware my AP/PDA number is the same,but the CSC number is different,is this normal?
this is apparently the stock samsung firmware for my phone PDA:I9300XXBLH3 CSC:I9300HTDBLH1 from the sammobil site, and after root mine says PDA/AP: I9300XXBLH3 CSC:I9300NEEBLH2
I would like to know if this is normal? Can i use the 4.1.1. jellybean (2012 October 4.1.1 PDA:I9300XXDLJ1 CSC:I9300HTDDLI1) on my phone using odin to flash it? Or do i have to find a firmware with exactly the same numbers as my current ones?
I am afraid i might have done something wrong,however everything works,and root checker says i have root access,and superuser is installed on the phone,if the toolkit has "updated" or changed my firmware/kernel to a uk one,does it matter?
Also,after root my phone now shows up as Galaxy Tab in utorrent,but it is still I9300 in my windows7, why is this?
Did toolkit 5.0 save my original rom/kernel/firmware before rooting? If so,where?
I would be extremely grateful for someone to easy my worrying
Thank You

[Q] Downgrade firmware from Australian carrier Jellybean to UK ICS?

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.

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

Galaxy S3 GT-I9300, back to stock - Baseband version?

Hi,
I'm sorry if this has been asked before but I ran a custom rom for a while on my Galaxy S3 GT-I9300 and now I want to restore it back to stock. According to my phone's menu, the baseband version is I9300XXUGNB1 but that version is not te be found on Sammobile firmwares. Can I safely install another rom with another baseband version? For example I9300XXUGNJ? (Netherlands). Or will I risk bricking my phone? To my knowledge the S3 I own isn't uncommon or anything. It's just a carrier- and simlock free phone which I bought at a major electronics retailer at the time.
Thanks in advance.
Hello and thank you for using Q/A,
you can flash all ROMs. But please keep in mind to backup EFS and then flash.
Kind regards
Trafalgar Square
so lets just say.. god forbid, the efs partition got facked at some point.. i may as well consider the phone bricked?
no you should be able to flash stock with odin and start all over (no root) if you didn't backup efs
not sure how its done though
