變磚過程
先前刷的CoreELEC9.0.2版本,想升級(jí)9.0.3。這個(gè)時(shí)候9.0.3的優(yōu)盤已做好,錯(cuò)誤的插在了N1靠近HDMI的USB插口,ssh輸入命令reboot update,然后去N1那里看,出錯(cuò)了!再重啟就卡在開機(jī)畫面不動(dòng)了,感覺是磚了……
總結(jié)
降級(jí)、刷錯(cuò)包、刷機(jī)時(shí)斷電,都可能變磚。
工具
電烙鐵和焊錫、公母、公公頭杜邦線若干、排針、鑷子、螺絲刀等拆機(jī)工具

用USB轉(zhuǎn)串口,連接電腦,設(shè)置串口號(hào)(設(shè)備管理器中查看)和波特率115200
盒子上電看到串口打印信息(論壇玩家說,有回顯說明沒真磚,BootLoader還在)。
進(jìn)入U(xiǎn)boot命令行:uboot命令行的啟動(dòng)方式,板子啟動(dòng)后在PC端的putty界面中通過串口快速按任意鍵或者輸入ctrl+c,即可進(jìn)入uboot命令行模式。
用戶由p230# 變成了 gxl_p230_v1#
在這個(gè)模式下,將N1降級(jí)恢復(fù)線刷的3個(gè)文件boot.img、bootloader.img、recovery.img三個(gè)文件拷到一個(gè)fat32格式的U盤中,(U盤必須是單分區(qū)的),一定要確定文件,沒有問題,必須是v2.19版本的。
將U盤插入N1盒子,putty中逐條輸入如下三條命令更新系統(tǒng)boot: usb_update bootloader bootloader.imgusb_update recovery recovery.imgusb_update boot boot.img逐條執(zhí)行命令后,串口返回的信息: usb_update bootloader bootloader.img 執(zhí)行返回: - gxl_p230_v1#usb_update bootloader bootloader.img

降級(jí)3個(gè)文件后,如果還是不能通過網(wǎng)絡(luò)進(jìn)入線刷模式或者短接觸點(diǎn)刷機(jī)依然失敗的,可以繼續(xù)看! 終極TTL大法 N1通過USB轉(zhuǎn)串口和雙公頭線同時(shí)連接電腦,putty進(jìn)入uboot命令行模式后,打開刷機(jī)工具選好刷機(jī)包,點(diǎn)擊開始!
在uboot命令行,可以通過putty輸入
串口返回信息見下面。

刷機(jī)開始,祝您成功?。?! 2019年9月11日補(bǔ)充: 刷機(jī)成功后,一定要重新【fastboot 燒錄】刷3個(gè)降級(jí)文件 如果不重新刷降級(jí)文件,會(huì)出現(xiàn)未知問題,已知的有: 1、有線網(wǎng)卡、無線網(wǎng)卡MAC不固定,藍(lán)牙不固定 2、最嚴(yán)重的,每次重啟卡畫面,一定要斷電才能正常重新啟動(dòng)。 救磚成功記錄 - gxl_p230_v1#update
