B806A不带后缀，2015年联通的盒子，线刷卡在4%，ttl里
进入m8m2_n200_v1#命令行，只有upgrade 命令，没有 upgrade_d命令，只能刷merge.bin文件，可是论坛里也找不到这个格式的固件，求助，谢谢。通过网盘分享的文件：M8S_aml_upgrade_package_16.0_20160229.rar

用这个线刷，刷机工具用2.0.5或别的2.0.X版本带key的版本。短路触发刷机工具联机。 本帖最后由 这是我 于 2026-1-31 20:49 编辑

多谢回复，下了这个版本的工具晶晨USB_Burning_Tool_v2.0.5.15-build9（带license），2.0.5没有找到，
现在是刷到6%中断，提示:
--UBOOT/烧录分区 boot/初始化分区/命令结果返回错误
--Close device handle 0x0000041c
btw：短接的是R23电阻。
很多命令没有，下面是版本号：
