There is no sim free rom... Search for "helroz" in market and unlock your phone!

Sorry don't quite understand the Sim Free ROM bit...surely there must be a ROM for non network phones such as sold by say Amazon UK?

He means exactly what he said there is no sim free ROM either use the tool noted or get an imei unlock.
Amazon phones are just sim unlocked mostly as non carrier branded.

I'm fine with unlocking...just want some information on non carrier branded ROM for UK? That's what i mean by Sim free ROM...

Ok just look in the original firmware "original development" CSC you want a UK "says what all csc's are in thread" they all non carrier branded.
All info for flashing is there too.
In same sub forum is also how to root.
And a sim unlock thread too.

Excellent...thanks for your help...

OTA for America?

I'm currently on LE9 which is not the latest version. Neither Kies nor my phone will recognize that there is an update. I could not find an American Odin tar for this phone in the general section with all the firmwares. Does anyone know which Odin tar i need? UK?
Edit: yes my phone is international
If your phone isn't the international model, i9300, you're in the wrong place.
Try the us forums.

I noticed that when i first turned on my phone, it asked what language to pick and by default it was selected UK. I changed it to US ofc but im thinking its the UK firmware.
Settings > About shows
Build Number: IMM76D.I9300XXALE9
I THINK the latest firmware is I9300XXBLFB. Correct?
Im also thinking that there is an American version because in I9300XXALE9 there is an A before the LE9 and there's also a I9300XXALFB out there
You can flash any of those, they will all be fine.
I'm on xxalf6 and I'm in Ireland.
Sent from my GT-I9300 using xda premium
what are the differences between the versions?
There aren't any changelogs so no one knows.
All the custom roms are based on XXBLFB since its the newest one out.

Thank you for your help!
Yours is Algerian version. Dial *#1234# and google the code that comes out that is how u find what region is your phone from. Thats what i hate about international phones, you get some phone that is made for some crap market lile african markets for example

That isn't necessarily true, XXBLFB is the newest firmware version out but it was released to lots of places, the UK, Africa, Germany etc.
ALE9 was released to lots of places too.

That's what I had in mind for the letters being related to build date rather than location.

so my phone is Algerian or no?
I don't understand why you can't just flash the latest update via Odin? I don't think it matters what you are currently on like it does on an HTC phone.

You have to find a Rogers rom somewhere, maybe on www.sammobile.com/firmware and flash it with Odin. Or else google around. This forum is for the Inernational version of the S3. Look in the US/Canadian thread.
You`re in luck here you find info:
PDA:I727RUXLF3
CSC:I727RRWCLF3
Phone: I727RUXLF3
Android Version: 4.0.4 Ice Cream Sandwich
source: Samsung Canada
*facepalm*
Well that explains your problem.
That rom is for the INTERNATIONAL VERSION ONLY.
This forum is for the INTERNATIONAL VERSION ONLY.
your need the version for the north American version.

See post 4 above and find a rogers rom in the US forum and flash it with Odin. I would get a jig to get into downloadmode.

Best bet is to head over to the forum for the at&t, sprint, T-Mobile and Verizon versions, nothing you will get here will work for your phone, they all share the same hardware whereas the international one is completely different.

The you'll need a jtag. Search for a repair shop nearby and ask them if they can jtag your phone. Costs a few bucks but allows you to access download mode again.

Unlocking in CM?

I purchased an unlock code so I can lend my phone to a buddy for a few weeks (I'm on Telus, he's on Rogers). Unfortunately, I don't think the ability to unlock your device has been cooked into CM yet. If it has been, can someone post a tutorial on how? If it hasn't, can someone direct me to a stock Gingerbread ROM using the v20a baseband?
EDIT: My "problem" is the inability to find a place to punch my code in. I've already tried “2945#*500#”, "2945#*71001#", and "*#865625#" all the while having a non-recognized SIM inserted into the phone. No result.
When I unlocked mine I had to go to 2.3.3. I just loaded dynamite for the unlock and then restored cm.

[Q][FIX] no network after Odin flash..FIX avaliable!!!

-----------------old post-------------My problem-----
HI everyone ....
i am not new to XDA but new to s3......
why does my brand new galaxy s3 which i bought yesterday has Vodafone apps and widgets.... its international then why..i bought this from Pakistan and there is NO such carrier as VODAFONE in Pakistan. i bought this its was brand new sealed.
info= pebble blue
=16gb
=baseband=i9300bulg2
build=imm76d.i9300bublg3
also i know the baseband is of another country and might be able to flash and remove this but my question is why.......................this phone was completly brand new sealed when i opened it yesterday and has vodaphone apps (bloatware) like wth..... ....... should i send it back or something lol.
EDIT = FLASHED UK ROM NOW I HAVE ANY NO NETWORK SIGN
UPDATE= SO AFTER THE NO SIGNAL ISSUE THE PHONE HAS BEEN SHOWN TO MANY TECHNICIANS BY THE SELLER AND FINALLY I WILL GET MY PHONE BACK TOMORROW ITS PRACTICALLY USELESS AND NO
SIGNAL TILL NOW GONNA FLASH FIRMWARE THAT IT CAME WITH ...TOMORROW....THATS MY ONLTY CHANCE.....
Update 3---- flashed stock firmware ....same.....but now it's says no service and that no signal sige
UPDATE--4 fixxed it with a modem patch..
-----------------new post below----http://forum.xda-developers.com/showthread.php?t=1918601-----
HERE IS THE fix^^^
You'll probably find its bought from the UK or anywhere else in Europe, flashed in Pakistan, then made available to sell....just flash UK firmware and it should be fine
anyone interested in blu-ray steelbooks, holla at your boy
You have bought a Vodaphone SGS3 .
Why you need to ask the seller .
As said looks like you have been sold an import .
jje
My s3 is a Vodafone import. Use galaxsim unlock to check if it's not networked locked. But since you can use your aim straight out of the box you should be good. Then Just flash a rom as speedyjay suggested.

Have you checked to see if the phone is network locked? Download galaxsim from the market and check your status.

Use one of the many efs tools and back up your efs, just in case it messes up. Then flash theroom again, then wipe data.

Just saw your post about nv_data error. If the stock flash isn't working it may be time to visit the Samsung service centre.
Try downloading roms from other countries, if it doesn't work then the service centre is your only option.

[Q] Unlocking Xperia U

Hi guys! Can I make sim-unlock on Xperia U , using unlocking code?
I have phone on contract (o2, UK). Also, I have bootloader unlock allowed: no
Is it posible to unlock sim, and use different network. And will unlocking code allow bootloader unlock?
Sorry my english
Yeah if you're on o2 and you got your phone from o2 they will unlock it free of charge, bootloader unlock will not change after you unlock it though

I don`t understand, why o2 can unlock it for free for everybody... maybe I want to steal it! If I stop paying, i can use it... They should block IMEI or something else... It's unbelievable
When you say unlock you mean to allow you to use it on other networks? If this is what you mean then o2 will unlock the phone for free if you bought it from them on a pay monthly contrAct
