Tutorial: How to flash International rom on Galaxy S3, GT-I9300_CHN_CHN (From CHINA)

If you are a proud owner of a Samsung Galaxy S3 (GT-I9300), but unfortunatly, your S3 was brought from china, maybe you have the versión GT-i9300_CHN_CHN.
This Version of Galaxy S3, has the bootloader blocked, then we can not flash international firmware in this model, because odin fail in modem.
In my first steps, i found a post with a firmware mixed a French files, and China Files in one Rom (thanks to XDA). But with ICS, ( 4.1.1). So because i like put he newest, i search around the net, and XDA, and i found some ways to do that.
This is the tutorial to do that.
STEP 1.
You Need to confirm, if really you have the Gt-i9300_CHN_CHN.
Put your Mobile on Download mode ( it show in chinese) and press Vol+, in the same way you do when you flash with Odin. (to enter Download Mode press: Vol-, Power; Home)
In the Screen Must appear PRODUCT NAME: GT-i9300_CHN_CHN, It´s means, you have a Chinese Version ( its International, But Chinese).
Another way its Pressing in your Phone *#1234# and its show your versión.
The latest version on china is:
GT-I9300 Galaxy S III
PDA: I9300ZCEMD2
CSC: I9300CHNEMD2
MODEM: I9300ZCELL1

http://www.hotfile.com/dl/204467117/3bfe5c1/I9300ZCEMD2_I9300CHNEMD2_CHN.zip.html
STEP 2.
Download the Latest CHINA FIRMWARE. and the firmware you prefer, I use the Spain (PHE)
The Official Link from Samfirmware:
Model: GT-I9300
Country: Spain
Version: Android 4.1.2
Changelist: 1287119
Build date: Thu, 27 Jun 2013 15:44:00 +0000
Product Code: PHE
PDA: I9300XXEMF6
CSC: I9300PHEEMF1
MODEM: I9300XXEMF6
Here is the Official Link from samfirmware:
http://www.hotfile.com/dl/233642717/ff467e6/I9300XXEMF6_I9300PHEEMF1_PHE.zip.html
STEP 3.
Once you have both firmwares ( china and your preferred firmware), you need to change the extensión of both files, you need to unrar your files, then you have something like this:
CHINESE FIRMWARE:
KIES_HOME_I9300ZCEMD2_I9300CHNEMD2_1133994_REV00_user_low_ship.tar.md5
SPAIN FIRMWARE:
I9300XXEMF6_I9300PHEEMF1_I9300XXEMF6_HOME.tar.md5
You need to delete the extensión .md5, it must have only .tar, just rename in Windows.
Then the both files we use are:
KIES_HOME_I9300ZCEMD2_I9300CHNEMD2_1133994_REV00_user_low_ship.tar
I9300XXEMF6_I9300PHEEMF1_I9300XXEMF6_HOME.tar
STEP 4.
Once you renamed both files, you need to unpacking.
To unpack your firmwares, you can use WINRAR, or another software who can work with tar files.
Or you can Use TOTAL COMMANDER, ( i prefer Total Commander)
https://mega.co.nz/#!WcUW3AbK!Y7yAFEL2nd_rApcW-DEliBCIokFG1em--FH28t5ifWY
STEP 5.
Once you have both firmwares unpacked, ( in diferent folders), you have to use some files from CHINA, and some files from Spain
In Both Folders we have these files:
Boot.img
Cache.img
Hidden.img
Modem.bin
Recovery.img
Sboot.bin
System.img
Tz.img
STEP 6.
From the China Firmware, I used these Files:
Sboot.bin
Tz.img
Modem.bin
From the Spain firmware, I used the rest of the files:
Boot.img
Cache.img
Hidden.img
Recovery.img (recovery can be omitted if you have a custom recovery and you don't want lose it)
System.img
We need put these files together,, if you have some software to pack files in Tar, Use it! ( with winrar you can only unpack, but you cannot repack)
In this step, i still Using Total Commander.
With total commander, you must put your files in the same folder, and click on PACK FILES.
The file resultant, is a tar file, ( you can rename the file as you want)
This file is flasheable by ODin, put in PDA just like another firmware. And flash it as the same way you know.
Remember: this is important: before you flash, you must do Factory reset, and format cache partition, in order to have a clean installation. ( many people dont do that, and after time, the mobile seems to have bugs, it is because need factory reset, and cache partition, so, DO IT!)
Once ODIN finish to flash, you must have a Galaxy S3 CHN, with Nordic Countries firmware, but with modem, and bootloader chinese.
There is Another Way to pack and unpack tar files, if you use Linux, search XDA for this, or you can use CYGWIN, wich is a Linux Console for Windows. ( search in XDA too)
With CYGWIN you can unpack and pack in tar and generate md5 checksum firmwares.
You Can change your firmware in other way too.
First you need to flash the CHINA firmware as it comes, without modifications.
Next you only need to open the Nordic Countries Firmware, with total commander, and delete, modem.bin, tz.img, sboot.bin, the rest of files still in rom. You can delete recovery too, if you have a custom one. (don’t forget backup the original file)
Then, Flash this rom without modem, via ODIN, in PDA, y that is all!.
Next you need to do Factory reset and Format Cache partition.
Note: CAUTION!, Backup your EFS folder, just in case.
Note 2: i don't test newest firmware, because the newest firmware from spain or Nordic Countries, are incompatible with the Structure and partitions in these firmwares, so, if you want use the newest firmware, try the new CHN firmware, and some firmware near to the build date of the China firmware.
If you mix incompatible firmwares, you will lost your IME.. DON'T BE AFRAID, YOU DON'T LOSS IT, IT IS JUST THERE, IN A DIFFERENT PARTITION.
In that case, return your old CHN firmware, and you will recover your IMEI, ( I do it twice)
I EDIT THIS POST TO CHANGE THE LINKS, SO ALL THE LINKS ARE THE GOOD ONE USING SPAIN XXEMF6.
THIS WORKS FINE, TESTED BY ME,
Enjoy

Nice job Cpaez. Now if only someone would figure this out (or if they have, share it with the rest of us) for the i9308, then all us China users would be set. i9308 is still SOL unfortunately.

is there any way to unpack the system.img , edit the files and pack it back into the .md5 file and then flash it with odin?

Maybe I can make a firmware for the users of i9308, Just let me know wich is your firmware, or compatible ( China), and what you prefer to have,(international or european), and i will make one for you. I cannot be able to test it, but, you can test it, and share your experience, you always can return to original firmware.

Does this also work for the GT-i9300_CHN_CU firmware?

First you need to unpack the rom, Modify the system.img, and repack the rom again, you can flash it without .md5 cheksum, just flash the tar file.
If you want the md5 checksum, you need to type this in Linux console:
$md5sum -t filename.tar >> filename.tar
$mv filename.tar filename.md5
If you dont have Linux, you can use CYGWIN, this is a Linux console for Windows.

probably, you can test it, i am uploading the file in Mega, i will share the file, you can test it, if doesnt work, you must flash again, your original rom.

Hi, i am new in this forum, so i hope i can use it in the right way.
First of all, thank you very much for this tuturial... very clear.
The model of my cellphone is GT-9300_CHN_CU, its safe to use this method? Before i flash any rom on my cellphone using Odine i want to backup efs folder and the current rom, so my question is, can i root my device with CWM using odin, this procedure wil not mess the bootloader?
Best regards

Odin with multiple files
Hi, i downloaded the official rom to my device (FACTORY_I9300ZNEMD2_I9300CHUEMD2_CHU), but i this file contains 4 files... BOOTLOADER_I9300ZNEMD2_1133994_REV00_user_low_ship.tar, CODE_I9300ZNEMD2_1133994_REV00_user_low_ship.tar, CSC_CHU_I9300CHUEMD2_1133994_REV00_user_low_ship.tar and MODEM_I9300ZNEMA1_862886_REV00_user_low_ship.tar.

Its, safe, you can do this with any firmware, many people change the modem.bin, to increase performance in signal, wifi, etc ( in our case we cannot do that).
There are many apks to backup your EFS, The most simple is with "Galaxy S unlock"need to be root in any case.
I root with Philz Touch and it works fine. You need to flash philz_touch_5.06.1-i9300.tar.md5 via Odin ( in PDA), restart in recovery mode, select install zip from sd card, and select Root_SuperSU.0.98-Busybox.1.20.2-signed restart your phone, and backup EFS folder.
Caution!, Root, and the rom you make with this tutorial, avoid your guarantee, because it is a custom rom, and increase the flash counter ( Red Exclamation Sign in the upper left of the screen during the boot)
You CANNOT, use triangle away, to clear the flash counter, because the bootloader is blocked.
Good Luck

I have a Problem flashing this Rom, I don Know was becaumy se the rom, or because HC-KTOOL, when i install this rom, i lost My IMEI, so, i think this rom is not compatible with the Chinese versión.
Backups your EFS folder, if you have trouble with this.
I will try later to do again, i recover my imei and my phone is working again. So BE CAREFUL AN DO IT UNDER YOUR OWN RISK.

I Fix It, It was'nt HC-KTOOL, was the firmware, SORRY, this firmware appear to be incompatible.
I Flash Again, another firmware without modem, and i recovery my imei.
Don try this firmware, or do it under your own risk.

I can't use triangle away!! so on the next year i can't increment the counter... there is one way to do that, with framaroot, right?
I think odin mobile is much safe than odin because it doesn't flash the boot and efs for our safe, so we don't need to care about mess efs folder and loose that important information.
And when the warranty finishes i can replace the bootloader for the international model?

Hi, i downloaded the firmware in two different places, one with "KIES_HOME_I9300ZNEMD2_I9300CHUEMD2_1133994_REV00_user_low_ship.tar.md5". And another in SamMobile.com witch contains "BOOTLOADER_I9300ZNEMD2_1133994_REV00_user_low_ship .tar, CODE_I9300ZNEMD2_1133994_REV00_user_low_ship.tar, CSC_CHU_I9300CHUEMD2_1133994_REV00_user_low_ship.t ar".
I extracted all the files and the files are the same and with the same size with one exception, the firmware i downloaded on SamMoibile.com have one more file than the other... this files is param.bin, this file is important or i can ignore it?
Thanks

Hi Cpaez, I was just about to try your method of combining a China Unicom ROM (in my case I9300ZNEMB2_I9300CHUEMB2_CHU, don't know why it's not _CHN, but that was what the phone came with) with the Nordic countries ROM (I9300XXEMG4_I9300NEEEMG2_NEE)
Now I got cautious, so before I proceed:
- It will always increase the flash counter if I combine firmwares like you describe?
- In that case might as well root (was hoping not to)
- There is no way of resetting the flash counter on Chinese firmware phones?
- Which firmware did you flash to get your IMEI back?
- Is the conclusion that you cannot marry the China Unicom firmware with the Nordic countries firmware?
- If so, is there another international firmware where it works?
Thanks

Hi Cpaez, I think your NEE firmware may simply have been too new:
http://forum.xda-developers.com/showthread.php?t=2377731
Apparently the firmwares from July onwards changes the EFS folder format, and I would guess that the problem arises because we are mixing the versions. I will try with a firmware from the same month/series (Bx) as my China Unicom.

Always increase the flash counter, i dont know how the phone knows is custom rom, even if the rom is made with oficial firmware.
To reset flash counter, you need root, you can root your phone, but, as i read in this fórum, theres no way to reset the flash counter, in this model, because of the restriction of the bootloader blocked. ( it need to Access the Bootloader, and it is dangerous)
I never tried to reset the flash counter, I don't care about that. so in my experience, i can't tell you exactly if really you can or cannot do it.
YES, You can Marry China Unicom with Nordic Countries, just not with the versión i metioned up.
My first rom was
I9300XXEMD3_I9300NEEEME1_NEE ( Nordic Countries) plus I9300ZCEMD2_I9300CHNEMD2_CHN( China), It WORKS great!
My Second Rom was
I9300XXEMF6_I9300PHEEMF1_PHE ( Spain) plus I9300ZCEMD2_I9300CHNEMD2_CHN( China), It WORKS great too!!
My third Rom was
I9300XXEMG4_I9300NEEEMG2_NEE ( Nordic Countries) plus I9300ZCEMD2_I9300CHNEMD2_CHN( China), It Mess My IMEI
When i lost my IMEI, y was in Panic!!! Obviously.! so i try to recovery with HC-Ktool, "unlock Samsung S", and nothing, I Use too EFS pro, And nothing, I was so worried, I delete EFS Folder, I Modify with Root Explorer, and Nothing, Even I format the EFS partition with "EFS Pro" ( don't do it if you don't have a backup of your EFS Folder).
I read in other post somebody, carried his phone, to Service, and they put a old rom, and he recovered his IMEI.
So i Flash the last Custom Rom who Works: I9300XXEMF6 and Works again, I recovered my IMEI.
I don't like have doubts, so, I flash Again, I9300XXEMG4, but, only flash the files boot.img, cache.img, system.img, hidden.img, without the china modem ( because the modem is right now in the phone). I LOST MY IMEI AGAIN!.
I just flash: I9300XXEMF6 and i recovered my IMEI.
In conclusión, i think, the newest roms, has diferent structure in the EFS partition, maybe It don't loss the IMEI, only the rom can't see it.
I will try to do with the lastest Spain Rom, if this Works, i will tell you.

We have to wait a new China Unicom Firmware, to mix New One.
I comment to You... the last that works is:

[Q] Upgrade/update existing firmware

hey guys!
Whether it be with ODIN 3.9 to the existing firmware G900FXXU1ANG2 suddenly to flash all three new file BL_G900FXXu1ANG9.tar.md5, kernel_G900FXXu1ANG9.tar.md5 and CP_G900FXXu1ANG8.tar.md5!!!

What is your question?
It isn't clear what you are asking. The best way to update with Odin is to flash the update, which typically goes in the AP (older versions: PDA) line. The update may or may not update the bootloader or modem in addition to system file changes. It depends of course on what the update pertains to.

How do I update to latest firmware through Odin? (Not the standard question)

Hi
As my country haven't gotten the latest update, I decided to download it through SamFirm (official firmware from Samsungs servers, just not capped in download speed like Sammobile).
But the thing is, that after decrypting, it's giving me 5 files and not just one .tar
The first 3 are named AP_xxx, BL_xxx and CP_xxx so it's pretty easy to guess where I should but them. But the last two files are named CSC_AUT and HOME_CSC_AUTO, so which should I use in the CSC slot?
Also, the UMS slot is greyed out, after putting one in the CSC slot and is stating that the firmware is only filling 65mb, even though it fills 1.8gb.
Anyone know what to do?
Thanks in advance

Hi,
Direct quote
"For some reason Samsung are now providing 5 files.
You now have some options:
1. If you want to keep your existing set up and just update, or reinstall existing firmware, you are better using SmartSwitch as described here:
http://www.sammobile.com/forum/showthread.php?t=29918
2. If you want to keep your existing set up, but want to install firmware with Odin, then use
BL - Bootloader
AP
CP
CSC_HOME
3. If you want to install another country firmware, or wipe your phone, then use
BL
AP
CP
CSC
CAUTION: This CSC contains a PIT file that will wipe your existing data and return your phone to 'out of the box' or will install another country/network firmware."
Cheers

Upgrading to Nougat using firmware from different region

Hello,
I am planning on installing the latest official UK BTU firmware on my Samsung Galaxy S7 Edge (SM-G935F), my CSC is CRC (Chile). Before proceeding I would like some help please. I know this may have been asked plenty of times before, but each case is different and in addition, I have some specfic questions about the process that I haven't been able to answer from other posts.
First of all, here is my phone info:
Product Code : SM - G93 5FZKLCRC
Original CSC Code :
Firmware 's CSC Code : CRC
Active CSC Code : CRC
Available CSC Codes : CDR , CHL , CPA , CRC , CTI , CTP , CTU , PCT , PET , PGU CSC
Country : COSTA RICA / CR Mobile Operator
Claro / 71203
I already have the official firmware and Odin, and the process seems pretty straightforward, extract the firmware, load it into Odin, put phone in download mode, flash. Oh! and hard reset seems to be the result of doing this which is ok. However, I am unsure about the following:
- The current firmware on my device seems to be Multi-CSC and I want to install a single CSC, what considerations should be taken when doing this? Is there any undesired effect?
- When extracted, the firmware package has 5 files: AP, BL, CP, CSC and HOME_CSC. I know I can ignore HOME_CSC, but, do I load all other 4 files in their respective field in Odin?
Should I ignore one or more of these files?
- Do I need a pit file and repartition or am I ok flashing without repartitioning?
- Can I easily go back and flash my original CRC Mashmallow firmware? Is the process the same but backwards?
Any help will be greatly appreciated. Thanks in advance.

Software update questions for unlock device flashed to ATT firmware.

Hello Everyone,
I'm a long time iphone user since 2013, and I just transferred to Samsung.
Recently I bought a new unlocked S10+ from samsung website. As a AT&T user and I need to use WiFi calling since my reception at work and home is bad. I did some search on the forum and flashed my software to 975U AT&T version, by using the files in SAT-1-9.0 folder in this link(https://androidfilehost.com/?w=files&flid=290649).
After I unzipped the G975U_SAT_1.zip files I got the BL, AP, CP ,CSC files, and I also downloaded the USERDATA file in that folder as well(USERDATA_ATT_G975USQU1ASAT_CL15296297_QB21819666_REV00_user_low_ship_MULTI_CERT.zip).
I try to search online find if I should upload the USERDATA into Odin but I'm unable to find any, but I did it anyway and upload BL, AP, CP, CSC, HOMEDATA all together.
The flash was successful and I was able to get ATT logo during booting and all the apps in the phone. Then I found out the SAT version of firmware is kinda old, there are newer updates available already.
Back in to that website folder, there are SBA and SD3 available as well, in SBA folder there are G975U_SBA_1.zip, 3.5 GB just like the previous SAT one, so I assume this is the main file. They also have USERDATA available as well and I saw the ATT one is in there too.
The SD3 folder doesn't have any "Main file", it only has USERDATA.
I tried to clicked check updates in the phone but it showing me my current software is up to date but apparently it's not(SAT version is back in Feb and there are SBA and SD3 already)?
Then I downloaded a new firmware (SD3) on firmware.science web last night and flashed it using the SD card, it wiped my data but the flash was good and the phone is now showing SD3 version.
My question is:
1. Will I get OTA updates in the future?
2. What does USERDATA do? I'm guess it let your software has specific carrier features, that's why the file name contains carrier brand name, the SBA and SD3 are all carrier updates, so if I want to flash to a newer version, I need to upload newer USERDATA into Odin, is that correct?
3. I flashed the SD3 using the MicroSD card. If I want to flash it using Odin, what should I do?
4. Is the SD3 file on the firmware.science website the same to USERDATA file in SD3 folder on androidfilehost.com?
5. How can I update without losing the data? Yesterday during the SD card flash I have to factory reset before update otherwise it will stuck at "Starting android" forever.
Thank you very much.
