I think maybe some baseband info is different. Are you using the same Portugese firmware? Maybe you need to do a data wipe and reset before flashing? I think this happens sometimes when we flash from one region to another. I tried to flash DBT (Germany) over my TGY (Hong Kong) and had this issue.
You'll need a flame shield against all those "Q&A!!!" peeps.
Anyway, mouse over the 3 letters you find on the website and find the correct version. Sounds like a bad flash to me. There's a 4.1.1 TPG for portugal.
Try reflashing and just wait it for a couple of minutes (5 mins max though) after first flash.

After the flash, it should re boot automatically. pull the battery before it reboots and put the phone back into recovery and perform a date wipe / reset.
Next boot should go all the way
People, I solved my problem
The original firmware was from TMN, but I installed one from TCL.
To solve the problem I did a data wipe.
Hi everyone,
this maybe a very noob question but how do you change the CSC on the S4?
I recently flashed an unbranded UK firmware onto my Australian S4, back with my old phone, I was able to change the CSC with *#272*IMEI# though that doesn't seem to work now. So any ideas? Any help would be greatly appreciated. I want to change the CSC to a UK CSC so I'll be able to receive updates OTA or through kies.
1.Download the appropriate firmware for your region from sammobile.
2.Extract Hidden.img and cache.img
3.Now compress these two files together into a .Tar file.
4.Flash this in PDA section of Odin
5.You now have correct CSC

Is anyone having trouble changing their CSC?
I've flashed the pre-rooted UK Firmware, and used CSC Changer to set the CSC to BTU.
It automatically re-boots, but the CSC hasn't changed.
I boot into recovery and perform a F.Reset, and the CSC still doesn't change to BTU.
As far as I can tell, I'm following all instructions correctly from here.
http://forum.xda-developers.com/showthread.php?t=2250824
"If someone want to change CSC, please use this app: Samsung Galaxy S2/S3 CSC
After using this app you MUST reboot into RECOVERY for the changes to take place.
Don't worry if you see some errors in recovery, it's NORMAL as "hidden.img" is excluded..
WORKS perfectly! TESTED!! "
I don't know what I'm doing wrong, and I'm getting increasingly frustrated!

Tried that without success. Got a failure in Odin.
There's no hidden.img nor cache.img but hidden.img.ext4 and cache.img.ext4. Are these the correct files?
I downloaded latest btu UK firmware
Loaded with odin
Did a factory reset
Switched if and then went into recovery mode
Rebooted and btu was activated
I was not rooted

they are just ext4 formats so u could mount it on linux or something else..
use mkuserimg.sh command to convert
I'm also interested in this. I also changed from Australian firmware to UK. Since changing I've noticed HD voice (wb amr) is off (check by typing *#0011# into dialer then menu key>back>menu key>key input >enter '1' then wait till menu appears >WB AMR Status.)
Prior to changing roms both WB AMR Setting and UTMS WB was On. Now they're both off. I did some searching and apparently its tied to the CSC.
so.....how do we change csc to s4? i have installed unbranded rom, wiped but csc remained the same. how de we change this?

I am also stuck after trying several suggestions of fixes..
The Sammobile firmware for NEE (Nordic) gives a CSC of BTU, i previously had H3G
Looks like we will have to wait till DEV's get time to build a work-around.
Doing web searches there are several dodgy sites that claim older changers work on the S4 & also giving instructions to install via the old way with the 3 files, instead of just the PDA.

i just reboted in stock android recovery (hold vol up + home button+ power),and it said "applied multi csc....and it changed the csc to the my curent firmware¨s csc
I am trying to set my csc to BTU. Im using csc changer app.
However everytime I run it, I dont get a screen allowing me to choose the csc as they show in guides.
I know the app works, since its changed my csc from EVR to DBT (since my rom is german based).
What am I doing wrong?
After playing around with several stock firmwares and Odin, I accidentally stumbled upon a method to change the CSC of my S4 I9505 without the need to root the device. I successfully changed from the original TGY (Hong Kong) to SIN (Singapore) and then to DBT (Germany). This is what I did (in summary)
Make sure you take a backup via Kies if you need personal files
Download the respective stock ROMS from sammobile.com or samsung-updates.com or see thread on Stock Roms on XDA
Extract zip to get tar.md5
Put device into download mode (Vol down+ Home + Power) and Flash using Odin (PDA option)
Wait till device reboots back into Android after completing the flash and recovery
Once device reboots, do a Factory Reset via Settings > Accounts
Once device reboots after Factory Reset/recovery, enter the google account info and restore settings and then turn off the device
Boot device back into download mode (Vol down+ Home + Power)
Re-flash the same downloaded firmware for a second time via Odin
Once the device reboots after the 2nd flash, your CSC should have changed to the CSC of the ROM you downloaded, and Kies also should show that CSC has changed and it should allow future updates via Kies or OTA

It's unnecessary to do steps 7-10. You may check your new CSC in recovery mode after restoring the device.

I was thinking so too but that's exactly what helped me to change CSC on my i9295 (very common with i9505). After the first wipe I still had the old CSC (I checked in Kies though). After the full procedure I have proper CSC in Kies. Probably there is a easier way but this one works also.

Of course I restarted Kies. I think what I have not done is entering Recovery once the Odin flash is done. Entering Recovery gives the following: Applying Multi-CSC... Applied the CSC-code: XXX (my new CSC here). And I think here's where all the magic happens.

At least for me, my device goes in to "Recover Booting" after each Odin flash as well as a factory reset. I actually tried a a manual recovery boot via Vol Up + Home + Power after the factory reset in step 6, but it did not change my CSC, hence doing all steps is what worked for me all the time. I once skipped the Google login part after the factory reset and it didn't work that time either and had to do another factory reset, google login and another re-flash.
I wish there is an easier way, the reason I have been experimenting with different firmwares is to see if I can get LTE working natively, since phone does not show the LTE option under Mobile Networks. We have 2 operators offering LTE here in Sri Lanka but Samsung only sells the I9500 officially here which does not have LTE, so got down my I9505 from HK. So far I have had to use Viaero 4G Toggle app from the play store to enable LTE, while it works, enabling LTE this way is a huge battery drainer!
but is there a way to extract CSC from a particular firmware and flash only this?
I used to do it on my S3 by using the hidden.img and the cache.img but if I try in Odin on the S4 it fails (
Hello,
I know it probably has been asked many times before but I can't see any answers.
Does using ODIN to flash the Lollipop update on my friends Note 3 mean that he won't then receive OTA updates after that ? He is a 3 user and although they have released the update he isn't getting it through OTA so I said I could update it for him with ODIN but I don't want to mess his phone up as it is all stock unmessed with at the moment.
Thanks
Not if you install the matching firmware that is the release for his phone .
Maybe if you install for a different CSC /Region/Phone Code .
Brilliant thank you!

I breaked knox counter twice {if that's what you meant} which doesn't allows direct update of software. But restored again.
TechArena.IN
> If you install the firmware from the identical CSC, OTA will work normally.
> If you install a different CSC, and the CSC is automatically changed to the new CSC after the install is finished (dial *#1234# to check), the OTA will work normally
> If you install a different CSC and the original CSC remains after the update, OTA will not work. To re-enable OTA: Do a factory reset through the Recovery menu to (automatically) change the CSC to the one matching the installed firmware.
> If you install a non-official firmware, OTA will not work.
I think that's all possible options.

Did you flash Marshmallow CSC? That is why
No, I flashed everything from the package I downloaded with samfirm. Ap, Cp, home_csc and Bl. And as I said I came from a clean installed nougat (the btu release from Dec the 30th).
Any other ideas?
I got the same problem. Tried to flash again did not help. Tried to wipe cache partition still the same.
Any ideas?
Try editing the csc in system manually to the correct one. Use the app phone info and check if original csc matches with installed csc. In my case there was no csc installed at all.
Did you ever resolve this issue? i have the same problem here
Read my last post
Yes but i had wipe all my data and start from scratch. There should be a way to do it but i could figure out. Good luck

As i said, it is caused by a missing csc. You have to copy the correct csc to the appropriate system folder manually and everything will be in order.

Feel like a n00b but facing the same issue but on NEE CSC .. exacly how do you copy the correct csc onto the system folder ?
(I do have TWRP and it is working fine)
I tried flashing the HOME_CSC again(actually three times) but that made no difference what so ever..
Any help appreciated!

Ok, first step is to locate your "sales_code.dat" file in the directory "system/csc" with a root explorer.
Change the access rights of the file to read and write for all user groups.
Now you have to edit this file with a text editor. If your root explorer has an editor included you can do it right away. TED Text editor for axample cant access root directories so you have to copy the "sales_csc.dat" to you internal memory, edit it and copy it back to "system/csc" by replacing the old file.
This file shall only contain your country code. In my case the file was empty, so there was no CSC chosen at all, which will mess up your settings menu.
So, just type in your desired country code (for example BTU for United Kingdom).
The second step is to copy the csc files for your country code to the correct directory, just follow this pretty nice tutorial here:
https://www.sammobile.com/forum/showthread.php?t=31670
Now just reboot your phone and everything should be in order.

Almost there. It is now showing me the correct "Firmware CSC" and "Active CSC" but "original CSC" is still blank and so is "Available CSC".
This is from the "Phone INFO" app.
The settings menu is now showing me the correct options, which is good..
O well thanks this far.. I'll see if I can get the last bits working too..
I have a similar problem now but i cant solve it. I once flashed the BTU Firmware with repartition. My original CSC is DBT so it installed the DBT CSC. Then i Updated it and had to manually change csc again to DBT so the settings were correct. Now i want wo update again and it does not install any CSC, not even with Odin. If i extract the sec_csc.zip from the home_csc file and try to flash it via recovery it just doesnt copy any files.
Does anyone have a solution?
Phone info shows me original CSC is DBT but the field active CSC is blank. i copied the files manually to the system folder but it still doesnt activate any CSC.
I had this too, and it was because i didnt installed csc. Maybe its your issue, too?
i tried to install the correct csc in multiple ways but it wont install and activate correctly. i tried via odin, tried to flash the extracted sec_csc.zip, treid to flash the non home csc. nothing worked. not even doing the repartition.
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:

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.

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.

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.

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.
