Teensy ++ easily reads and writes dump in the PS4. It remains to change the offsets in the dump and downgrade ready.
Ps4 have flash memory ps3 have nor and nand memory. It's quite another memory so e3 does not give advice

You can buy flash memory such as the PS4 and play with them, then take a dump with the PS4 and modify the dump.

Ideally having for instance 4.05 do dump upload 4.06 to do a dump and compare that offsets change.
dump from low OFW are available on devwiki so you can pull the offsets and embed them in their own dump. Clean the drive and keep trying to upload 1.76

sorry for my English

No, you really can't.



The reason a downgrader is still not available (and may never be) is SAMU's fault. Firmware is encrypted and decrypted upon system boot by SAMU. Since the keys are locked inside the hardware, unless by some miracle they're found or a hole is present in the encryption system (which is possible), external encryption/decryption isn't possible.

Tools are ready to break up dump owners part.

Guests on youtube just replaces part of the dump in order to repair the evaporation falls



3 dump compared with the same PS4 various FV and offsets that are changed after the update are repeatable
I think the substitution offsets from 1.76 to 4.06 dump
flash memory already been ordered from aliexpress
I am also looking for PS4 tests in Poland

At least I can fight
The PS4 uses a nand chip not nor. And e4 flasher? Not sure y they would change the name on it. Still would be used for dumps/flash of a nor chip

Specter has stated you can't. I'd go with what he said since he knows what he's doing.

That being said, thread closed.
