Hello, would first of all like to that everyone that contributes to the vast amount of knowledge on this forum.
My question(s) pertain to:
1. Confirmation I do indeed have a corona v3 motherboard (Picture attached)
2. Materials needed to successfully complete my RGH
(I have all the necessary soldering tools)
Once confirmed I plan to purchase:
- Slim Proto V2
- J-R Programmer V1 Or V2 - Leaning towards V1 unless V2 is necessary
- PostFix V2
- X-Clamp removal tool
Is there anything else that is needed that I have overlooked? Or do I not need something I have listed?
My understanding so far of Rater is limited. Does Rater on J-R Programmer V2 not work on Corona V3? Is the R2C4 bridge fix used to make it work?
3. Confirmation of my understanding of what I need to do:
I know that the resistors R2C7, R2C6, and R2C10 must be bridged. My motherboard has all the resistors already in place, so I am do not need to bridge them right? (info says to bridge only if resistors are missing, but also say V3/V5 must have R2C10 bridged for NAND R/W)
(Picture of my resistors attached)
My main focus is to just order the parts I need, any additional information is just a plus at this point. Thank you very much.
