[Q] How to revert back from 4.3 to 4.1.2 (Malaysia Region) - Galaxy S III Q&A, Help & Troubleshooting

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.

[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

Thank you for the answer. I understand everything now.. And it works fine.. I did however use the wrong firmware rom,so i got different operator,i found the correct stock firmware,and will be starting from scratch using the cf-root method with the correct stock rom.
Thank you

Hi
my phone is also with Unknown baseband and it wont connect to the mobile network. It is not a problem of the sim as the same works on other phones. I tried to restore the original firmware/do a software update but i cannot connect to Kies and over Wifi the upgrade is failing with a generic error of Processing failing.
This has happened after I rooted the phone with Odin.
I know that restoring the baseband could fix it but how do I go about it? Could you point me to the right instructions on how to get it back to life? For instance where do you get the basebands and then how do you flash the phone ?
Read the stickied modem threads .
But i suggest you flash the stock firmware through Odin .
Its all in the stickied basics .

If you got an unknown baseband usually a re-flash of the original firmware solves it, you can download them on know websites as for instance sammobile.com. How to flash a ROM or baseband/modem please have a look in the FAQ thread and stickies. You can find a collection of modems in the General section's baseband/modem thread.
Restoring official firmware didnot work

For my I9305 i tried to flash the original firmware I9305XXBMF1_I9305EVRBMF1_EVR (The UK version for EE) but still the baseband is unknown and the phone is unable to connect to the network. It looks like i need to actually install a Baseband rather than flashing with the firmware (still not 100% sure on the difference and which on excludes the other for what)
I am reading the FAQ but i might want to wait for this before using Odin again.
Has anyone got a recommendation for a baseband for Samsung S3 LTD - I9305 ?

How to downgrade from stock 4.2.2 to stock/custom 4.1.2 rom?

Guys I have been having a hectic time with this no network issue in my i9300. I upgraded from 4.1.2 to 4.3 without backing up the EFS folder and tried to come back to 4.1.2 and then the network registered problem came. So after many failed attempts I flashed the stock 4.2.2 via odin and gave my phone to a shop and got the corrupted EFS folder done with the repair box. Now the thing is when I flash Neatrom or the Omega 4.1.2 roms I do not get the network. I get my network ONLY on my stock 4.2.2 rom which has the patched MG4 modem. Please help me to downgrade and install Neatrom 4.1.2 rom and get my network back.
I have got a backup of my 4.2.2 EFS folder.

hello, I know there are plenty of threads regarding this. I went through all of them. I just want to know if anyone else encountered a problem exactly like mine.

Cant seem to get this right

Hey guys, I was recently on a custom Rom, which i liked but had so many bugs
I heard good things about the newest 4.3 update, the ones with all the bug fixes so im trying to go back to it
I flashed a really old 4.0.4 version, which for some reason was in dutch? and it had taken away my Imei and luss i couldnt change the CSC within the menu
Ive tried countless other firmwares and ran into nothing but trouble, I tried the leaked 4.3 firmware which was a Irish vodafone version and i couldnt do anything with that
Sam mobile is pretty much useless with the new host, can someone please give me a link which has the right firmware ( Unlock Galaxy S3 gti9300 ) normally i flash BTU. So yeah, The right firmware, where I can update to the latest 4.3, quick download speed and a firmware which has everything included ( I.E IMEI, Signal Etc )
Many thanks, Jack
You'll need to understand the basics if you are going to repair what you've already done to your phone.
Flashing yet another rom won't fix it, if the 4.3 firmware didn't.
You can't repair the imei, unless you have a backup of the efs folder. Instead you'll need a repair centre.
Start with reading the sticky threads in general forum, in particular efs 'know this stuff'.

[q] imei lost after unroot

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.
