Hi,I've found the custom recovery boot TWRP for the A15 (https://twrp.me/samsung/samsunggalaxya154g.html).But i can't any custom OS for this device. Nothing on LineageOS, /e/os or Iode.The GSI Rom is really a pain to install or can't found an easy tutorial.Does anyone have any information on how to install a custom operating system on this device please?Thanks
