华亚芯片HTV903,升级难,已是众所周知的,多见是可读不可写,近日无意中从厂家获悉,该芯片的接收机升级接口多数可以直接用COMS来升级,但必须在接收机处于升级状态才能升级,[ post]要升级,不不仅要正确接好RT、XT、GND,还要设置好接收机,使之处于升级状态,方法就是:电源开关为关机---按住接收机的“菜单键”不放→按通电源开关通电→5秒后→恭喜你是不是有升级画面了!好吧!大家尽情升级啦

我是单晶的5812,打开华亚升级工具serial_app.exe,设置全默认
flash 10000
偏移 10000
烧录长度 0
然后下论坛上那个《华亚HTV903+5812单晶振.img》
点开始,马上开电源,看到进度条走,然后一直等到进度条走完,屏幕上开始显示我上面贴的刷机信息,耐心等十几分钟再也没字出来,重启,搞定……
唯一有点不完美的是刷完我的遥控器上几个键失灵了,不过不妨碍用,皆大欢喜
