Google Wallet issues after may security update

[tomesiek]

Google walet showing message that phone not meat security standards after update. Just me or it's a app problem. My phone is NOT rooted and fully official software.

It looks like there is a newer version S918BXXS5CXDF/S918BOXM5CXDF/S918BXXS5CXDF for EUX region. Maybe this will solve our problems.

Same problem here. Tried flashing EUX firmware with no luck - bootloader prevents firmware change (bootlader and OS signature does'nt match), and bootloader itself cannot be flashed cause of anti rollback feature (new bootloader must be higher version). For now, the only solution is to change CSC back to default one and wait for OTA update from our region.

I returned to EUX region. manually download the newest  software and flash it. after it return to sek region. the status in google play (i think) change ones per day. now it is not certified. but after flashing I was able to add cards to wallet. I think that in S916BXXS5CXDF/S916BOXM5CXDF/S916BXXS5CXDF can be all right. will se.

You flash CXDF manually via USB cable, or using regular OTA?

[Serhii3]

manually via USB cable through Odin

OTA CXDF not found at the moment...and I stopped rooting because I don't want to spend time with Odin! Hope the fix arrive soon...

You can't flash CXDF over CXDE - both firmwares have same bootloader, and flashing only OS will fail cause of bootloader-OS signature mismath. And you can't flash bootloader cause of anti rollback feature until newer version will be available

[Serhii3]

You are wrong. CXDE has the same loader = S916BХХS5CXDE as S916BХХС5CXDF. so it was very easy to do by Odin. I did not roll back. I make a flash with newer software.

[Serhii3]

I can send you a photos with after OTA upgrade and after Odin flash.

I've already tried that - and phone refused to launch cause of bootloader - OS mismatch
