Motard Geek

hello dear friend i bought the ortur obsidian at its launch in 2020 and trust me i have always had problems with the firmware. I have read the whole chat and I was wondering if you then determined which is actually the final firmware to use. I release the latest v62 and the printer restarts with white display sometimes, sometimes it freezes, sometimes it turns off the hot end while it prints and continues to print. Well can you help me ?? Thanks in advance
note: initially the ortur diagnosed that I had a corrupt motherboard and then they sent me a new one that I mounted but same problems with the firmware.
