The "PS4 Tool Downgrade v100.exe" is highly likely to be a scam or malware
You cannot "downgrade" to any version you want. You can only to the immediately preceding firmware version installed on your console. This is because the PS4's motherboard contains two "slots" for firmware: one for the current active version and one for the previous version as a failsafe. How a Legitimate Revert Works
Stay safe. Don’t run random EXE files. And remember: if it sounds too good to be true on the PS4 hacking scene, it always is.
A: Possibly — if you were previously on a lower jailbreakable firmware and never allowed the console to fully download the 12.50 update, and if you have the necessary hardware backups and skills. However, for most users who bought consoles already on high firmware, downgrading is not possible.
The "v100" in your search refers to Firmware . People want a tool to roll back from 10.00 to 9.00. As of 2025, there is no software-only downgrade from 10.00 to 9.00 . The hardware fuse count prevents it.
A real downgrade requires opening the console, soldering wires to these chips, and using a hardware flasher (like a Teensy or Raspberry Pi) to dump and modify the chip data.
Help you find if a specific is able to be downgraded.
While fake, some files might attempt to write corrupt data to the system, making the PS4 unusable.
Authentic firmware reversion is possible but requires significant technical skill and hardware modification.
: Tools like the TNC++ or a Teensy board are required to interface with the chips and dump their data.
Are you comfortable using to run exploits?
Any website, YouTube video, or forum post claiming you can plug your PS4 into a computer, run a file called ps4_tool_downgrade_v100.exe , and lower your firmware is a scam. Why Software-Only Downgrading is Impossible
For the vast majority of users, the safest approach is to:
The PS4 tracks its firmware version in two primary hardware chips: the (System Controller) and the NOR/NAND flash memory .
