Thanks for the answer. Regarding this Youtube video (eMMC method with QNX access). Can I follow that specific tutorial for my unit? Is there anything that differs for my 5Q0035819B version softwarewise? I fix mobile phones, so I have microsoldering equipment and I am confident with the hardware part. I am willing to take the risk of bricking the unit, because if it fails, I will just buy a new unit anyway. My main question is: Do I really have to crossupdate to firmware 0480 during this eMMC process like they do in the video? Or can I stay on my current 0369 firmware and just patch the filesystem within QNX to enable developer mode/SmartLink? If I need any specific files or modified dump for this exact 819B unit, please let me know. Thank you!
