Xecuter Corona 4GB RW QSB V4
These are the Xecuter Corona 4GB RW QSB V4, they are used in conjunction with the R/W kits to read and write to the Nand on the Corona 4GB consoles. Note these are the very latest V4 models of the QSB’s and different to the ones shipping in the R/W kits currently. The difference is these Corona 4GB QSB V4 can be used on the Corona 4GB v2 motherboards but they now also fit perfectly on the Corona 4GB V4 boards as well. The QSB’s that shipped with the R/W kits were only designed to fit correctly on the Corona 4GB v2 boards, while they could be used on the V4 corona boards they didn’t fit correctly because there was two batches of resistors that the old QSB would sit on top of and so the QSB would not sit flush with the motherboard. This has now been addressed with the Xecuter Corona 4GB RW QSB v4 and they now sit flush on the motherboards on both Corona 4GB v2 & v4 boards.
