Quick 'n Dirty prepatched
http://www.ps3devwiki.com/files/firmware/MFW-CEX/Downgrader/
- PS3MFW Features Enabled
- Change PUP build / version
- Patch LV1 (downgrader) checks
- Patch LV1 hypervisor: Allow mapping of any memory area (Needed for LV2 Poke)
- Patch LV2 kernel: Patch to add Peek&Poke system calls to LV2
- Patch package installer: Patch to allow installation of pseudo-retail packages + debug packages
- Patch Application launcher: Patch to allow running of unsigned applications
- Add new icons to the XMB Game category: Add Install Package Files + app_home + icons to the XMB Game Category
Quick syscon rehashing
Goal: To be able to install unpatched firmwares on consoles that where previously on 3.56+
The FSM dance
NOR only, for now! Don't use directly as is on NAND, because offsets will differ!
Patch files used
Depending on which step, will be used in one or both ROS areas:
This will be the same for all steps:
After each step of patching, enter Factory Service Mode and reinstall nonpatched firmware (e.g. OFW)
Step1
| Target area | Patchfile | NOR Offset | Paste length | Remarks |
|---|---|---|---|---|
| ROS0 | ROS-empty.bin (7 MB) | 0x0C0000 | 0x6FFFE0 | |
| ROS1 | ROS-empty.bin (7 MB) | 0x7C0000 | 0x6FFFE0 | |
| trvk_prg0 (0x40000) trvk_prg1 (0x60000) trvk_pkg0 (0x80000) trvk_pkg1 (0xA0000) |
RVK-0x40000.bin (512 KB) | 0x40000 | 0x80000 | one big patch overlapping several revoke area's |
Step2
| Target area | Patchfile | NOR Offset | Paste length | Remarks |
|---|---|---|---|---|
| ROS0 | ROS-filled.bin (7 MB) | 0x0C0000 | 0x6FFFE0 | |
| ROS1 | ROS-empty.bin (7 MB) | 0x7C0000 | 0x6FFFE0 | |
| trvk_prg0 (0x40000) trvk_prg1 (0x60000) trvk_pkg0 (0x80000) trvk_pkg1 (0xA0000) |
RVK-0x40000.bin (512 KB) | 0x40000 | 0x80000 | one big patch overlapping several revoke area's |
Step3
| Target area | Patchfile | NOR Offset | Paste length | Remarks |
|---|---|---|---|---|
| ROS0 | ROS-empty.bin (7 MB) | 0x0C0000 | 0x6FFFE0 | |
| ROS1 | ROS-filled.bin (7 MB) | 0x7C0000 | 0x6FFFE0 | |
| trvk_prg0 (0x40000) trvk_prg1 (0x60000) trvk_pkg0 (0x80000) trvk_pkg1 (0xA0000) |
RVK-0x40000.bin (512 KB) | 0x40000 | 0x80000 | one big patch overlapping several revoke area's |
Redump flash after last reinstall of firmware in service mode to check if both ROS areas are occupied.
Alternative QA way
- Patch as normal downgrader (ROS 0/1 + RVK prg/pkg) on mainpage
- install prepatched firmware in service mode
- enable QA-extra and install unpatched firmware in recovery mode.
Alternative shorter reFSM way
- Patch as normal downgrader (ROS 0/1 + RVK prg/pkg) on mainpage
- install prepatched firmware in service mode
- install unpatched firmware in service mode
