Help flashing nand without a device

Hi guys, I was using the Bad Update exploit and after 3 hours of attempts it finally worked, I used the simple flasher to dump the nand and J-runner to create the XeBuild.

In theory with this steps completed, I could flash the modified nand with simple 360 flasher again, then do the soldering and complete the rgh3 without needing anything else? I know simple flasher could fail and I will have to use a physical flasher in the end, but my question is: could this work properly? Would be the chances on my side?

I have a slim model with trinity 16mb.
