The new version XBReboot for all NAND 16MB only was published. This new image must solve the problems of freezes / lags which appeared on some games and also removes the need to patch your XEX (mediacheck).

As a reminder, XBReboot is an image of NAND flash on the console to hack JTAG.

-- Who are the authors?

Members talented XBH who have contributed by their skills. The XBR Team brings together all these contributions, development utilities, and assembles all for this to work.

-- How it works?

Whether or XBR Freebooter, both use an "engine patch for applying patches to bootloaders to reboot the console. Freebooter regard, it is "freeboot.bin" or "Freebooter-manual.bin"; to XBR, it is "xbrfw.bin" These are two binary-based startup code Xell and are launched by the exploit. The code then applies the patches contained in block 0x65 + and reboot the system.

-- What went wrong?

The XBR 1éres versions used the same pair of CB / CD to run the kernel and the 8955 feat. Freebooter, using a system of dual-nand, using the old bootloader to launch the exploit, then used the new bootloader on the flash side to start the kernel.

The problems were not related to the patches used by XBR, but rather to use the old bootloaders. Try to control when problems occur, they can always be corrected. Do not throw in conspiracy theories, the purchase of Cygnos, install a dual-nand or xD Card, to convert a nand 256/512 in a smaller etc ... Have a little patience and rationality.

-- What are the corrections?

1) Adding a copy of the new bootloaders on the flash.
2) Create patches to use the new bootloaders set up on new addresses to reboot.

It was easier to re-use the engine freeboot.bin patch for this work. Patches of Freebooter itself is not used. XBR still uses its own patch, however, the engine patch freeboot.bin be used to implement them. This also allows the patching custom format used by Freebooter.

XENON_8955_3:

- Use the CB 6750 as an alternative to allow easier support for all versions of hardware.
- No changes to the patches, they have exactly the same functions as 8955_2.

XENON_8955_2:

- Added a new copy of flash bootloaders.
- Creation of patches to use the new bootloaders set up on new addresses to reboot.
- Conversion of existing patches in XBR for use with engine patch freeboot.bin.
- Fixed build file to use the CB / CD 1921 for all Xenon.
- Remove the check to the XEX XEX launch from any media without the patch.

-- Composition of blocks XBReboot:

Ox00 - 0x2F Xell Boot firmware
0x30 - 0x3F Backup Xell
0x40 - 0x4F freeboot.bin gold-manual.bin Freebooter (patch core engine)
0x50 - 0x61 Alternate CG
0x62 - 0x64 Spare blocks
0x65 - 0x65 Patch.bin, patches for bootloaders and kernel
0x66 - 0x8F Alternate CB / CD / CE
0x90 - 0x? Flash file system

- Notes:

It is no longer necessary to extract the files and recreate SAIP. It is a limitation of Freebooter and not XBR. Apart from this difference, all functions are identical. Each section can be updated or retrieved separately via NandPro.
