Before iodéOS, I had installed CalyxOS 6.8.21 with a relocked bootloader (avb_custom_key.img).
Unfortunately, Calxy unexpectedly closed its doors. Two leading figures, Nicholas Merrill and Chirayu Desai, have left the Calyx team. More = A letter to the CalyxOS community
The installation of iode-6.6-20250803-bangkk by @ronnz98 went completely smoothly.
