I installed Iodé OS 10 days ago.
(Like everybody ?) I had to unlocked my bootloader.
Iodé 3.2 install was a success, but upon every startup, my Samsung S10e complained about the phone’s bootloader being unlocked.
So I had the marvelous idea of relocking the booloader.
Upon next startup, my phoned refused to boot, because the firmware was not an original one (these are not the right words, but the general idea of the XXSmall red text).
So I unlocked the bootloader again.
Next screen displayed “Erasing…”.
Result : I lost everything I did with this phone since installation.
Bottom line : Do not try to relock the bootloader.
