Hello, Since a long time, i've a Minix Neo X8-H on the firmware KOT49H.20140809. I wanted to update it directly in firmware version 9 20160324 with the tool USB_Burning_Tool (2.0.6) provided, but this resulted in an error "0x30403003 UBOOT / Partition system / Download buffer / Data tranfer error " after 4~5 minutes... Since then, I have tried everything: - reflash the beta version which worked: /forums/neo-x8-x8-h-002-beta-8-firmware-20140809.66/ - flash version 002A: /threads/official-002a-firmware.2413/ - try different version of USB_Burning_Tool (from 2.0.3 to 2.0.9) I do not have a good result and my Minix is broken. Black screen, but, I still see it on USB_Burning_Tool I specify that I did not try the method with the SD Card because I do not have one. One of you has a solution. Thank you !
