Here is how iit was done with the components, you need to transform your corona v2 motherboard like if it was a corona v1, both motherboard are the same except they have some component that are different around the nands
Here is what you have to take off:
TOP MOTHERBOARD
-the phison chip
-R1E1, R1E2, R1E3, R1E4
-C1E6, C1E7, C1E8, C1E9, C1E10, C1E14, C1E15, C1E16
BOTTOM MOTHERBOARD
-the corona v2 nand (of course)
-R1R1, R1R2, R1R3, R1R4, R1R5, R1R6, R1R7, R1R8, R1R9, R2R2
-C1R1, C1R2, C1R3
This is what you need to solder back on:
TOP MOTHERBOARD
-the corona v1 nand with the injected corona v2 ecc
-C1D1, C1E17
-R1D1 & R1D2
BOTTOM MOTHERBOARD
-R2T1, R2T2, R2T6, R2T7, R2T9, R2T10, R2T11, R2T14
Al parecer tendrian que convertir una Corona V2 en una V1, generar un ECC a partir de la nand CORONA V2 (de eso no tengo idea cómo) y deberia mostrar el Xell con la respectiva CPUKey
