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
Added: 2013-04-14

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 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?

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.

I noticed after i had the problem! LOL!!
We have to wait a new China Unicom Firmware, to mix New One.
I comment to You... the last that works is:

Hi!, FMB Lima, Are you ever test newest firmwares?, working?, i will try the newes CHN_CHN, i Hope Its Works, i still in the i9300XXEMF6.
I just puchased a yotaPhone 2 and as all of us know there is no native update button in phone ,i downloaded firmware through yotaflasher but cannot find it in my PC and showing error ..where to download the firmware from and where to place it for flashing the firmware,can anyone please provide me detail instructions on how to flash lollipop on this phone . thanks in advance!
Yotaflasher should take care of all that, it stores firmware in the firmware sub folder. There is no need to look at anything. Just select download zip, then select flash in yotaflasher.
Try repeating it.
For detailed instructions, plz read the other posts on this Yotaphone group .
Also don't forget too put your phone in download mode! And make sure windows finds the drivers for the phone or you'll be really frustrated!
hi,i tried to upgrade to Lolipop but now i'm stuck.Using adb devices finds my device connected but when i write adb sideload <filename.zip> does nothing and after a while i get the message in my phone E:footer is wrong E:signature verification failed.
I have tried with 4 different firmwares ..same result.Any ideas please? i'm stuck in the Android system recovery and can't do anything with the phone.
Don't sideload the zips from the yota ftp - they can't be flashed like that.
Instead use yotaflasher. If needed delete the folder where yotaflasher is installed on your PC, then reinstall it again.
In YotaFlasher download latest RU firmware, put the phone in download mode ( power+ volume down) and start flashing.

- I bought YD206 CN firmware(4.4.4) and downloaded the latest firmware(5.0) under CN directory of YOTA firmwares and successfully installed it using Yotaflasher.
- After upgrading, model number reflects YD201 and the build number - LRX21M.5.0.0-HK1.1.124d
My question is can I flash the latest RU build on the firmware mentioned above?
Thanks in advance.
You need to flash RU 124 and then update with OTA to RU 134.
So in conclusion If I have HK 2006 phone Is better to upgrade to 5.0.0-HK1.1.66.zip and after that need to flash again if I want EU or RU version, never do that directly because would be problems.
I yotaflashed yd206 from HK 4.4.4 kitkat to latest Russian kit kat, then did an OTA to get the latest Russian lollipop firmware. No problems, but there is a long wait at the yotaphone animation for 5 minutes after lollipop upgrade.
I had no problems with radio (frequency bands) on newly configured Yd201 but I live in Asia.

So you say is better to upgrade the firmware from HK 4.4 to RU 4.4 and then i flash the firmware again with 5.-.-0?
No, only 1 flash is required using my method, HK4.4 -> RU4.4
You can then update RU4.4 kitkat -> RU1.1.124 lollipop by OTA (Over The Air) because it can then be updated directly in the phone settings. This OTA must be done anyway in order to get to latest RU version.
The size of the OTA is 1GB, a huge download. During the first boot up of the lollipop, there is a very very long wait for lollipop to start for the first time, where it updates all your apps to new lollipop format. Be patient at the yotaphone animation during first lollipop boot up.
I'm not saying my method is better, I only use this method because I read here that a few people had problems flashing directly from HK 4.4 -> RU 5.0 But Many people have successfully flashed direct from HK4.4 -> RU1.1.124
Forgot putting the phone in download mode

So I did, and you right know I am really frustrated. My yota is stuck on "Powered by Android" screen, what can I do? Posted more information on this thread: http://forum.xda-developers.com/showpost.php?p=69919853&postcount=24
Hello, I have recently installed Android 8.0 (Unofficial) on my S7 edge as mentioned in this thread by ProtoDeVNan0. And also installed TWRP recovery as explained here to upgrade it. After installation figured that it has some issues with some features.
So now I am trying to downgrade to the latest official firmware.
But every time I download and install the official firmware zip file using TWRP, it says the zip file is corrupt. So I tried downloading from different sources and still it says it is corrupt in TWRP.
And then I tried using Odin after extracting the Zip file. Using the tar.md5 files inside it. It fails as well.
And also found no way to install the official recovery.
Is there any way I can downgrade from 8.0 to official 7.0? And also I would like to remove TWRP and install official recovery. Basically returning it to its original state.
Searched a lot and found no possible ways to do so.
Please help. Thank you
SOLUTION:
I have found the solution to the issue.
I previously tried using odin to load all the packages in the zip file all together which was the reason i was getting the error.
The solution is to tick and select AP file only in odin and start.
(in case stuck at meta-data unplug)
Then reset odin and re-start the phone into download mode again.
Now tick and select the CSC file (not HOME_CSC), and then start.
After the phone reboots, a factory data reset will occur and phone boots up.
Why are you using TWRP to attempt to install Official samsung firmware?
You do it all through ODIN, it'll put your device back to basically original setup state with stock firmware. Flash with CSC and not home_CSC, I assume you have no data you will need to backup before hand.
More info here:
http://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin
Which Version you use odin? I try your solution but dont work on my g935f?
BL not downgraded!

STILL NOT DOWNGRADED!!
You can apply the solution described above (using ODIN to flash AP, CP and CSC with a previous version of firmware). However, the Boot-loader will remain under the latest version (since January 2018 update).
The problem is drastically worst for those who used to patch certificates before the January 2018. For those users, I will advise to not install the update from January 2018 because, they will not find any tools currently available to patch certificates and get the phone work a new. They can try but it will not be successful and the phone will keep saying "Emergency call only" or "not registered on network".
Anyone having successful experience to inform others please!
Thank you.

Yes it Solved. You Need to have Stock Firmware of March , and extract PIT File, then flash Firmware with PIT File.
In Options tab check "F. Reset Time", "Auto Reboot", "Nand Erase", "Re-Partition" and "Phone Bootloader Update". Rest options must be UNCHECKED!!!
If anyone need Firmware of March for G935F and the PIT , then let me know.

You must Flash it with Odin, with PIT , you must do it how i sad it in my last Post. I Upload Firmware and PIT now to Mega.

Sorry if my english is not good, i'm confused where to go for help.
I also experienced the same problem. I just tried installing android 8.0 (from the same link and way as you explained) and it works. but after I tried several times, a lot of bug that makes me uncomfortable.
So I plan to restore it to the official/original firmware version as before. I've tried using odin and also the same as you experienced, always fail when installing BL. And AP, CP, CSC works well.
Then, what should i do?
Can someone please help explain to me more clearly? with more easily understood words. My English is not very good, I still have to use translator for sentences that I do not understand. I would appreciate your help.
Thank you

after trying for many days got this Solution.
The baseband should be same or higher of the firmware to downgrade.
Example: G935FXXU2DRAG Oreo
G935FXXU1DRAG Nougat ( will not happen.)
Both should be same I mean the U2 in the middle.
Or u can downgrade upgrade from U1 oero to U2 Naugat. But not from U2 to U1 Baseband.
Hope it helps.
Just download last nougat release and flash it using latest odin simply guys,
I have tested, no one needs to use pit file or nand erase etc. Use samfirm to download latest firmware for your model. Then use latest odin to flash. Be sure to use normal csc file, NOT the home csc. You don't need pit file when using normal csc, its included with it.
If you used twrp recovery etc to flash unofficial oreo releases, you need to first confirm if oem unlock is enabled, don't tick on auto reboot option, just tick F.reset from odin options, then first flash latest nougat for your region through odin, then flash twrp through odin. Then when odin says pass, force reboot into twrp recovery from download mode, then format data in twrp and flash super SU/magisk and no verity opt encrypt. Then reboot and you will be good.

can't downgrade
odin gives "FAIL" when starting the procedure.
i have the U1 nougat version and the U2 oreo version.
can't seem to find U2 nougat ( if any) and I guess upon upgrading to OREO sonething had changed and can't downgrade anymore.
I managed to get into android recovery and did a factory reset and total wipe but nothing, through ODIN flashing doesn't work.
Any ideas anybody ? I really want to downgrade so I will be able to install stock nougat, and flash an oreo custom ROM with magisk in order to get around the KNOX triger thing.
tks

You can't flash U1 nougat on U2 oreo firmware. It has been all over xda that U2 firmwares has Version 2 bootloader which can't be downgraded to Version 1 bootloader of U1 firmwares. Nougat has many U2 firmwares, you simply need to search..

bluetooth start works but need switch off battery optimization
Hello everyone
I found it!!!
Problem with your bluetooh connection after upgrade can be solved in one of the way follow previous post or "disable battery optimization.
I try before swichng off and on all networks, emergency mode etc. and nothing happen.
Disable battery optimization
Sometimes battery optimization also messes up with Bluetooth connections. I suggest you check battery optimization settings and remove Bluetooth from it. To do so, follow the steps:
Open device Settings and go to Battery. There is few ways to go there:
first can be: open settings go to "device maintenance">>>clik on "battery">>>clik on "batterry usage">>>clik on 3 dots right top corner>>>then clik "optimise battery usage">>> and u are there - swich off “Bluetooth MIDI service” and apps that you use with Bluetooth such as Play Music, Phone, youtube, maps etc.
2nd
open settings Tap the 3-dot menu present at the top right corner and select “Battery Optimization”.
Turn off Battery Optimization for “Bluetooth MIDI service” and the apps that you use with Bluetooth such as Play Music, Phone, youtube, maps etc.
