Flash dhivael's SPI uboot (risky)

[clover]

I think my SPI is not corrupted because when there is a boot device connected, the led goes green like it was loading a kernel... But I do not understand it. One time I was able to enter loader mode even when my SPI was broken using recovery button.

The recovery button is iffy at best, from what I have gathered from the community. It is not a consistent method of getting into maskrom, sadly.

The lights are a good sign that your pinebook is not terribly broken, though  still i recommend bypassing SPI altogether. which should be a surefire way of getting back into maskrom where you can flash zeroes to your SPI, and then flash either Dhiv's or pcm720 (since you know that works for you if you want to be done with Dhiv's)
