Hello Guys. I went into a bit trouble here...
I have Samsung S3 for more than 1 year, and I already flashing it with custom ROM without proper backup (foolish yeah i know)...
And now, I want to return to my official stock rom (unroot). Since i am from Indonesia, I found that the latest firmware my country has from S3 is 4.1.2 (from samsung-updates and sammobile websites) like this :
GT-I9300 Galaxy S III
PDA: I9300XXEMF6
CSC: I9300OLBEMF3
MODEM: I9300DXEMB1
Added: 2013-07-23
I reset the binary counter with triangle away and unroot it with mobile odin, but the problem is my imei was like "0049...../1" and I cannot make any calls or sms (not registered from network).
After reading a bunch of threads, i found the solution was to root it back again and install modem XXEMG4...
Is there anything I could do to have a working unroot phone? like using official stock rom from other country perhaps?
cheers
Yes it is the Modem problem. And for heaven's sake as soon as you root make a backup and backup your efs partition as well before you get into a bigger mess. Flash a stock rom that has the modem MG4 or flash a 4.3 rom of any country it hardly matters.
If i unroot it with a 4.3 rom from any country, then can i update through option "software update" or should i flash it again if there is any update in the future?
Thanks for the explanation!

no i dont think...but you can try by KIES..that may be possible..but some users have reported that kies also doesnt work for them..but you always have ODIN to flash firmware of other country or any your country whenevr it comes..
:good:
So i still have to root it?
Root doesn't matter, you cannot use the firmware of modem for your country as it is efs v1 and you didn't take a backup before you changed to v2.
There is no way back, you'll just have to wait for 4.3 to be released in your country if you want stock and unmodified status again.

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.

I have the international S3 GT i9300 and have been waiting for the Jelly Bean 4.1.2 update. Being the impatient person I am I got bored and download the 4.1.2 Touchwiz ROM for my phone and flashed it with Odin without root. However, now as the update is near, I'd rather have the official version. So I'd like to revert back to 4.1 so I can get the update. Kies is saying it isn't compatible with the firmware but is this because it isn't out yet? If its going to always say this, and it will affect later updates, how do I go back to 4.1 without root? Or will I need to root? On the other hand, if this wont affect anything and will be the same as the official, then shall I just keep with what i have?
Thanks alot
Restore your exact saved original firmware .
Or restore it from CHECKFUS .
t isn't compatible with the firmware but is this because it isn't out yet
No you no longer have Samsung firmware that matches the codes .
Root has nothing to do with updates .
Simplest would be to read the Guides .

I already have the 4.1.1 firmware which is kernal and ROM, can I just flash this in Odin?
Thanks for the help
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
hi all,my sg i9100zslpg 4.0.3 show imei & baseband unknown,,,,plz help me to fix it,
i search forum but not understand clearly much to fix it,plz guide me,
thanks.
Try flashing some stock roms. If that doesn't work, it's a fairly expensive trip to a service centre or somewhat less expensive trip to a local mobile repair shop.
can you link me with that appropriate stock rom for such problem,or can i try with new jelly bean 4.1.2?
Go to Samfirmware, choose a rom for your carrier (important with this issue in particular) with the pulldown boxes, download the rom, unzip the tar file, throw away the .dll & flash the tar in the PDA section of Odin. And pray as it reboots that your IMEI will be back when you go into settings/about phone/status. You already know what will be happening if you still have the generic IMEI.
my device is rooted,does i need to unroot it first and can i flash the 4.0.4 jplpj on it?
Do not flash 4.0.4. Stay away from it. That you don't know flashing stock firmware will remove root is illustrative of why you find yourself in the position you're currently in.
ok,as i understand you that firstly i unroot device then flash rom,
can i use 4.1.2 XWLSD?

No need to Unroot the phone ma8, just flash the Stock JB 4.1.2 XWLSD firmware pertained to ur region from PC Odin and it will unroot ur phone for u
Alternatively, u can also use 'Mobile ODin' on ur phone (which is rooted for now) to flash the same Stock JB 4.1.2 XWLSD firmware pertained to ur region
Hi guys. I need some helps. I'm from Malaysia and the android that i used before is android 4.1.2 I9300XXEMF6 (original firmware). Then ive upgraded it into android 4.3 (I9300XXUGMJ9) for UK region. Even though it is an official samsung firmware, i found out it is unstable. I flash it back to android 4.1.2 (Malaysia original firmware) but something happen. The "network have not registered" problem. I then found the solution by rooting it and install the modem. But it act funnily as the android seems unstable from before. I flash it over and over again hoping that reverting back to 4.1.2 will be the same as before but i ended up using 4.2 as the 4.1.2 have network problem. I already search the forum and find many solutions but none provide the files that i need. I also have tried KIES method by recovery and initializing method but it resulted the same. "Network has not registered. The only solution is to root it and i would really like to NOT to root my phone.
My question is, can someone provide me with necessary files such as the pit files, phone (modem) and the CSC files that specifically for Malaysia regions? I already have the firmware file. Please guys. The instability of 4.3 is driving me crazy.
BTW im using i9300.
Stop.
You are going to brick your phone if you flash things without understanding them.
Go to general forum and read the sticky post, especially efs 'know this stuff'.
Flashing a pit file WILL brick your phone.
When you flashed 4.3 you upgraded to efs v2, there is no way back. You can only use EMGx and later modems now, find a later modem that will work in your country, either with 4.1 or 4.3.
Edit. Backup your efs, perform a factory reset, flash your 4.1 country rom then an EMG modem.
hey man, thanks. One question, where can i find this emg modem?

What you`ll need is a new version of 4.1.2 with a mg4 baseband or latest, the 4.3 rom changed your efs folder format. If you want to stick with your 4.1.2 go to http://forum.xda-developers.com/showpost.php?p=43946365&postcount=15 and flash that emergency.zip (mg4 baseband), it should do the job.
Hi guys. Already solved the network problem by installing the Modem DDEMG2 files via odin. Thanks for your guys helps and advice. For some that thinks that i haven't read many posts, i have read them but cannot grasp the concept. Sorry for the inconvenience. Many thanks.
