noob questions about cr4xl and jrp

[monsta182003]

Hello modding experts. This is my first rgh attempt. I have a corona v1 board and i am attempting to get the cpu key. I already bought the following: cr4 xl, jrp2, jrp/nandx cr qsb v3.

I read a few tutorials on this forum unfortunately most refer to cr3 and the guide in jrunner refers to jrunner v3 build 1 but my jrunner updated to beta 7.

The guides for installing the qsb and cr4xl were straight forward but no mention is made about the connectors on-board the cr4xl , the qsb and jrunner v2.

After I connect the spi-nand cables to qsb there are 2 more white connectors on the qsb what are they for? (wondering if I have missing cables)

What is the post_ttl for? and Should i connect the cr4xl to the jrp using the post_ttl cable?


Can someone please help me with some answers or If someone could point me to an updated guide that covers this i would be grateful.

Got an answer about post_ttl from a post:

the post ttl port on the cr4 is for the rater feature of jrp v2 and the jrp v2 comes with the cable.

don't try to program the cr4 because it will be trash if you do.

also if you use the small via for the point you lifted I would tape it down to secure it. I wouldn't use hot glue because if you ever need to remove it it might lift the wire trying to remove the hot glue.
