Corona With Phison And Hynix Chip Options

[ravendrow]

so a friend brought me his 4gb slim to RGH it looks like a corona V2 so i hooked up the sd card reader it detects the chip but says its size is zero...after taking it out of the case i found a hynix 16mb nand soldered to the bottom of the board so i tried to dump it via SPI and i get some jacked up flash config. just wondering if anyone has seen both chips present on the board and how i should go about dumping it oh not sure if this is supposed to happen but when i was trying to use the sd card method to dump the nand i noticed when i connected the main xbox 360 resonator to ground and plugged it in the fans spin up fast and after about 5 seconds there is a tick unhooking the resonator stops the tick when you plug it in but it still says the size is zero
