Black Screen After Jtag Attempt On Jasper Bigblock

Assuming the nand is messed up, can a working image be reconstructed using the keyvault and rawconfig?
Flashconfig is 0x008A3020, so the config is on 0xEF7, correct?

I managed to run an old xbr.bin by injecting kv and config and now i have the cpu key. Its the only thing that boots though. I don't know what i'm doing wrong but i can't compile any other bin that will load. Also it takes about 2 minutes to boot. I tried j-runner,xebuild and others but i don't have a good nand dump...
