I own a Redmi Note 12 4G NFC that previously had OEM HyperOS EEA 1.0.9.0, I decided to return to Xiaomi.EU ROM, NFC was working before then (and on Xiaomi.EU ROM ver 1.0.4.0 too)
I boot into Xiaomi.EU 1.0.5.0 (This phone has yet to be rooted as of now), NFC was working then,
I installed the latest GPay_module apk, I setup Google Wallet but [This phone does not pass security checks]... I reinstall the GPay_module, clean data on Play services, Wallet, Store and reboot... and on the way i noticed that on the Wallet app "NFC is turned off" even if I press turn on on the app, I assumed it was just because i haven't passed safetynet yet.
and then i realized something is very wrong, as I can't turn on NFC at all (I press the switch to turn on, it turns off immediately, I cannot switch to HCE, it is stuck at SIM Wallet)
I backed up my apps except banking and settings, I did a factory reset, same result.
I flashed the latest stock fastboot MIUI 14 EEA ver 14.0.12 without locking bootloader, i boot into OEM MIUI 14, same result
...this is an issue.
I took some logs (via adb logcat) :
the pinned file is the logcat of what happens when i attempt to turn on NFC (here I did it 2 times)
it looks like the NFC firmware is corrupted...
is this recoverable without opening the phone and/or replacing the NFC chip ?
EDIT : As a last ditch effort i reverted to stock MIUI 14 and locked bootloader, NFC is still gone.
EDIT2 : I have found the suspect, and it is unrelated to Xiaomi.EU, the official crDroid firmware (which is what I was originally flashing before HyperOS 1.0.5.0) refused to work on my device despite being made for it, and there's an active discussion on the Telegram group about this exact issue.
I don't know how to delete this post, so if a moderator can, please and thank you.
