Question Indian firmware with European Z FOLD 4 (SM-F936B)

[gregou]

I just saw online that India Market got the new update (F936BXXU1AVIH) with September security patch.

So my question is, as i have an european model with the same model number (F936B), what is the risk if i flash this firmware ? As i know that it's not gonna change my 4G/5G bands anyway, so i'm guessing maybe an OTA issue after flashing this firmware (like not receiving them as i don't live in India).

Sorry if it's a stupid question :-/

No risk, CSC HOME and all good. I do it.

Ok, thanks for your reply
And what about future OTA updates ? Will it still be working ?

 

[megatooth]

Yes.

Yesterday I installed the Indian version on my European version Fold 4, there is no problem except that it does not pass the Safetypass and I cannot make contactless payments.

No Root, no OEM unloock, just ODIN upgrade (firm from Sammobile).

I confirm that i can no longer make contactless payments as well, but i never used it anyway so not a big deal for me... i hope that there will be no others bad compatibilities like this one.

Will update on a newer European firmware later or just flash the AVIH European firmware when it'll be released

But you have flashed also CsC?

Yes i flashed Home CSC too (to keep my data as it was before the update

It's strange,because Home CsC not change your original CSC

I'm guessing that it's caused by the software itself and not caused by CSC. Maybe in India, Google Pay is not used, i don't know...

It's very strange that the India version does not pass Safetynet's CTS checks. I also used the Home_CSC, I had never had a similar problem. I will wait to try with another region when it comes out.

Same here....Some week ago I bought a Z Fold 4 with EUX CSC and immediately changed CSC to INS using SamFW ver 2.1, Wallet worked like a charm until latest security update installed some days ago...Now, reverting CSC to EUX, does not solve the problem...

So you're saying that you reverted back to the last Eurpoean Firmware and that you can't still use GPay ? Or you just tried to changed the CSC without flashing European firmware ?

Yes, I reverted back to european firmware without success...

Maybe we have to wipe everything to get it working again when reverting
