I read all the available guides and tried with a lot of custom roms... how to change CSC???
I tried *#272*IMEI# and set a new CSC, from the available list. Phone reboots and seems to flash something by showing the progress bar. But after that *#272*IMEI# or *#*#1234#*#* show me again the original CSC code!
The only way I got successful is by flashing CSC from Odin. In this way I loose compatility from ROM versions... and sometimes I noticed lags in rom functionings.
HELP!
Where I'm wrong??

Tried also to manually copy CSC folder (under /system/csc/ITV) to corresponding folders... overwriting original files...
Now I can see ITV when pushing *#272*IMEI# but with *#*#1234#*#* I can see OXA again!!!
Remove required CSC files as above from original rom or CSC rom .
Custom rom open with win rar or 7zip do not extract .
Delete CSC folder delete CSC files and CSC version text delete SW Configuration XML file .
use ADD tab to add original CSC files to replace those deleted .
Close zip and flash via CWM .

Tried (with Cognition Rom) but typing *#*#1234#*#* I can see OXA again.. even if the only CSC available in the /system path is ITV!
Typing *#272*IMEI# I can see only ITV.
Also, how to check the CSC is set right? Are there other checks available?
Hello,
trying to repair an error that is bugging me to hell. When you run the recovery than thers a thing, this thing ('/system/csc/MOT/system/', proceeding with MULTI CSC)
So I was thinking that when I would flash it with the correct CSC file from my carrier MOT and get rid of the the Multi one.
And yes, does any one know why is my stock recovery written in red? Da faq ;/
I know that i can edit the previous post, but let this serve as a bump.
Is there a way lets say I could copy my carriers csc into the multi one and delete all others and then rename the whole flashable zip with the right name as it were my carriers separate csc file and just integrate it into the multi csc file. Probably I can do it this way, but in the multi csc zip there are three files in it;
- cache.img.md5
- GT-I9070_EUR_XX8G.pit.md5
- hidden.img.md5
so which of them should be modded to? How are those two files involved in the cache one which has the csc info? Why is there a pit file again? Or in other words.. which files trigger the correct order to successfully apply the modded csc.
If you can help me, I can guaranty that there will be "thanks" raining as Im not alone with this problem.

Have a nice day
Ive been doing some reading on creating your own rom using samsung stock. What im wanting to do is use the system.img from marshmallow, and combine that with the rest from oreo (to get around the downgrade disable). Knox is already tripped i dont care about that...
both roms have the 5 tar.md5 files when extracted, AP, BL, CP, CSC and home CSC - however, to extract those once again, marshmallow contains regular disk image files, .img while oreo contains bin.lz4
Can I either, leave these different compression styles within the tar.md5 files, replacing the oreo system.bin.lz4 with the system.img from marshmallow, compress back into the tar.md5 and try flashing. Or, is there some clearcut way to convert either the bin.lz4 into .img , or the other way around? Has anyone done this before?
I was able to extract the bin.lz4 using diskinternals linux reader which produces a single file, simply labelled as "file" under the file type (windows 10). but what i cant figure out is if that is correct, and if so how to turn it into a regular .img file. the file sizes, between the bin.lz4 and the "file" ones are the same, which makes me suspect that this isnt correct. 7zip wont open the lz4 files at all.
Id love some advice from here. I know this is alot of work just to downgrade, but I am determined. Id love to figure this out! It would be my own personal way of saying "screw you" to samsung for locking things down so hard... also Im looking for that full touchwiz experience, for anyone whos about to suggest a custom rom. maybe its "chunky" but i love it.
Okay so I have managed to extract the XAA csc files from the G973U and decrypt them. I'm wondering if there's a way to use them on a G973F to make it the correct region. How do you go about setting which CSC is active, I can copy the XAA folder to system/product/omc but not sure how to activate it. In BeyondRom you can select which CSC to be active on installation so there has to be a way to set which CSC is active. I may try just switching out the files from XAA to my current TPA CSC folder and see what happens.
Update: After some investigating it seems you can change the CSC with the Phone INFO app as long as you have root, the only CSC available to change to though will be the OXM ones. I am thinking if I replace the whole OMC folder with the OMC folder from the G973U it may work. I will have to decyrpt all the cscfeature.xml and cscfeature_network.xml files, not difficult, just a bit tedious.
Would love some input on this.
UPDATE 2 I have attached the link to all the USA CSC files. It is 100% possible top use the OMC CSC files from the G973U on the G973F. I just tested out using the XAA csc and took a screen shot for proof. I needed to modify the mps_code.dat, sales_code.dat, add XAA to the sales code list and add XAA to the SW_Configuration.xml.
OP updated
If someone could use the Phone INFO app and tell me what their "Product code" is on a G973U1 that would be great! Would like to try changing the product code all and see if Samsung Pay will work.
EDIT: Found the product code for the USA G973U it's SM-G973UZKAXAA for the unlocked phone, and then for TMobile it would be SM-G973UZKATMB.

How did you change your CSC with Phone INFO? Mine doesn't let me.

Yeah the Phone Info way didnt work, what I did in the second update in the OP did though, but it didnt allow me to get samsung pay to work so I will try changing the product code at some point. Make sure to do a FULL TWRP back up including your product folder before doing any if this incase you mess something up.

I actually was able to get SW Version to say TMB/TMB/OPS. Everything works except RCS, although the video calling option is hidden (still works though). As for the product code, for some reason I am unable to access the IMEI folder. It's super weird, I can see it through a root browser, but can't modify anything. When I try looking for it through TWRP's file manager, it's hidden. I want to replace the prodcode.dat with a USA one so i get full support, but can't seem to modify it. What are the permissions on your folder? Mine may have gotten screwed up.

Im using Root Explorer.
Thanks! Could you also send the owner permissions for the imei folder as well please?
Edit: Nvm I got it. Have the TMB firmware installed, everything works except carrier version is showing 0.0.0. Gotta figure out how to get the TMB branded carrier version on here. That's what solved RCS on my S7
I am quite interested in this. I got a exynos. Id like to add cricket csc to
Hi, after some experimentation, I got the full T Mobile CSC to work on the exynos phone. It requires modification of the EFS folder + a carrier installer zip from mentalmuso and the CSC files from the carrier firmware. Basically you manually set the efs files to the make/model of the CSC, flash the zip, and replace all the files in the product folder with your firmware files. I used it for TMB, but I'm suspecting that permissions/folder names will need to be modified in the zip for it to work on other carriers.
