do you know if it ever worked? I just tried mine, and it shows 2.70.
at one point it did show 2.70, but I did something. It has to be the IDPSet I wrote to both eid0 & eid5 so that might have changed it to 3.65 but now I can't change it back even after reverting back to the original IDPS
Perhaps, since you used an idps from a 3k, it manipulated lowest FW to a higher one and it's a one way street, so to speak..?
I did it my PS3 shutdown and I looked at the file is it suppose to be so small its only 1 kilobytes
Also my ps3 is 3001A
It's supposed to be 16 bytes.
same thing happened to me when i spoofed with a 3001 IDPS/PSID on my 2501A.
i made a dump with 3001 ID and my minver was 3.65.
i just dumped eid_root_key for 3001 ID and then restored my original IDPS/PSID from 2501A using IDPSet (writing to eid0/eid5) and reboot
must be in CEX mode lol
after reboot i can dump eid_root_key for original 2501, also minver is again 3.50! vulnerability? haha
mine won't change back to 2.70 after doing that
try using rebug 4.21 to do it or reinstall rebug 4.81.2 twice maybe?? idk? that method worked for me! i had dumps of both eid_root_key files though for each ID used.
also i had to resign the IDPSet for 4.xx, but works good!
maybe try changing to fake ID and write, reboot, then write real one. make sure all 3 files are on usb000 (idps.bin, psid.bin, eid_root_key)
nope neither worked
I dont get it, so i dont have anythng interesting to say, but it looks you hitted with something interesting
I’ve got a 4xxx Idps if you want to see if it’ll go higher again rather than lower for the minverchk?
is that firmware the lowest downgrade version of the 3x model?
I'm pretty sure yes, I'll have to check later as @ work now
I'm thinking I might grab the IDPS from the phat nor model I have, possibly get it lower then 2.70
We discussed the possibility yesterday with esc0rtd3w, he was supposed to give it a try.
If it actually worked, it would be a vulnerability we might be able to use (on CFW compatibles anyway for now)...
For some reason my original still shows 3.65, might it be possible I bought it with a spoofed IDPS? I could have sworn it said 2.70 at one point, i could be wrong.
On your original is the 8th byte 0C or is it 09?
