Hello everyone,

 

My Tmall Magic Box 3 emmc clear Unable to boot what should I do.

 

Repeated display:EMMC:0;READ:0;CHK:AA;SD:800;USB:8;

due to no vendor binary blobs to build uboot, restore to vendor OS is the only way to unbrick. these binary blobs are for memory init, power sequency.

now your device is bricked, you can just try VIM's u-boot or p212's u-boot.

 

只能重新刷成出厂的云OS。你看看国内论坛有没有。例如：znds.com等。

既然你的设备已经坏了，可以试试VIM. 或 p212的u-boot。这样可以重新安装成Linux/Armbian，但安卓/云OS只不能了。

不懂可以私信我。

if you want to try VIM's u-boot, armbain supports VIM, you can download armbian and flash it to SD card.
