Despite several attempts at reflashing, the issue persists. I have a suspicion that the baseband component might be problematic, though I must clarify that I'm not a professional and this is merely speculation on my part. Nonetheless, I'm hopeful that the development team can offer their expertise and assistance in resolving this matter.
