Solved installing EUX XDF and changing CSC to XXV from SamFW tool to keep call recording function. Now Wallet is working and device is certified but Samsung pay doesn't work

using home CSV, do you mean that if I now have SEC, I should go back to EUX and only then install the firmware? is it difficult to use ODIN,?

Hi.
It really easy and takes around 10min.
Download firmware (you can use Frija), unpack

Load all files to Odin3_v3.14.4 like on picture

Put you phone in Download mode, click start and wait, phone boot automatic.

Just remember to use file HOME_CSC_OXM, other file CP_file will wipe your phone to default setting, HOME file will keep your CSC and settings.

If you have any more question HOW TO feel free to ask.

Thank you very much, now everything is clear, I’m already downloading the firmware and odin. I still have one question: after buying a phone in Portugal, I changed the region through SamFw to SEK Ukraine so that calls could be recorded (screenshot above). Do I need to return to my region out of the box before installing the update?

[tomesiek]

no problem.

No, when you use HOME_CSC_OXM, everything will stay the same. Your current CSC, and all your settings.

There is a chance for no OTA update later, but then you need to change CSC to EUX, update phone and then change again to CSC you want (SEK)

@tomesiek I wanted to add my thanks! Your forum message came at just the right time.

I am on eux firmware but historically changed csc to ins to enable call recording. Google Wallet worked up until my phone updated the other day, when it stopped. I updated security and play system, and it worked again for a day, then stopped again. 

So now I changed the CSC back to EUX and I have downloaded the latest EUX firmware via Frija, which I found out about thanks to you (downloading off sammobile or whatever was crawlingly slow even after paying!) and I'm hoping that installing it via Odin does the trick.

It is great that there are such helpful people as yourself.
