Guys, i hawe this situation. After power down, the HFM stop recognize all two card - no ignition, remote not work. Im read processor in HFM (car is 2018), RET can't read ISK/PIN CODE with dump. Data_flash in HFM looks like corrupted, many FF, status HFM in RET is "clear". Can i learn virgin (another) HFM using RET without PIN CODE/ISK? Or maybe it's possible repair data_flash?

Simply read by OBD2 the PIN code using <Read Identification> button of R.E.T , if you can't > renault.net in main dealer
Normally in this case disconnect battery 10 minutes can resolve this problem , if not > renault.net in main dealer

You need original car PIN code to learn virgin HFM so when original HFM dump is corrupted and no PIN code inside, only dealer can help you.
