  1. Patch as normal downgrader (ROS 0/1 + RVK prg/pkg)
  2. install prepatched firmware in service mode

Above is already done if you just downgraded

Dump the flash first, in case you brick on dehashing, you can easily flash this one back to debrick

  1. Put console in service mode with JIG (in case you left service mode and ran the prepatched firmware in normal mode)
  2. Use normal lv2diag.self and unpatched official firmware (e.g. 3.55) on USB Mass Storage device in root and let the system reinstall that in factory service mode (FSM).
  3. After installation is finished console will turn off. Check UPDATER_LOG.TXT in root of USB Mass Storage device (it should have "manufacturing updating SUCCESS(0x8002f000)" in end section).
  4. If everything is OK, then reinsert USB Mass Storage device and let it install again.
  5. After installation is finished console will turn off. Check UPDATER_LOG.TXT in root of USB Mass Storage device (it should have "manufacturing updating SUCCESS(0x8002f000)" in end section).
  6. If everything is OK, then console should now be dehashed and no longer brick with any unpatched firmwares.
  7. Replace lv2diag.self for he one getting out of service mode and put in root.
  8. Power on console, it should turn off and not boot XMB.
  9. Remove USB Mass Storage device and boot console normally. If all went well it should load to XMB now. Congrats, you now finished downgrading and dehashing. Console runs 3.55 and any firmware of choice can be installed, no longer needing to be patched for downgrader.
