So have console that I want to revert back to stock firmware, I do NOT have original nand dump from it just updflash file, and the info in form of cpu key, KV info. Can it be reverted to stock ?
yes, I believe so. you need to dump the nand, then in the smc type choose retail. I don't know if the chip being inside still will make a difference, but it's doubtful.
Well i have tried and no luck getting error from jrunner of unknown SMC , I can attach full dump incl keys here it makes no diference. for some strange reason console was working was left in attic and now is dead as dodo.
