[SOLVED]data error (cyclic redundancy check) --- Corona ECC write

hello tx long time no see.I'm trying to rgh my corona v4/v5? (not winchester) - 4gb onboard mui have a homemade usb reader and successfully dumped nand (48mb in size)what is the next step? I failed to write ecc to board with data error as said in title. I have nothing bridged, is that required as stated in the guides? (i thought it needs to be bridged to boot xell, not write ecc)tried power cycles and 3 different readers.- and Y3C1 is connected to groundback in the day you would read nand, write ecc, install your chip then boot. - do i need to have my cr4 installed to write the ecc?also, cr4 is pre programmed right?thanks for reading

run a hdd testing utility on pc this error means the hdd had a head on crash with platters usually caused from dropping pc check the smart status of the hdd and report back and no you dont need it installed to flash ecc u need it to boot but not to flash yes cr4 is pre proggramed

UPDATE: I WAS ABLE TO FLASH ON A .ecc file, but still reads nand as full 3.6gb? - did it work?

yes

yes

SUCCESS!!! Successfully booted into xell and grabbed key. For those with similar issues (data error) all I did was a power cycle about 6-7 times and it finally wrote to flash. Keep Jrunner open throughout this process and keep pressing write like 3 times before a new cycle

ALSO:
(I was able to connect the POST OUT without the adapter!----- I literally shoved a wire into the 4th pin and held my iron against the wire until it stuck. Not a sure sound way but it worked!
