Enso Ex Installer Vita

Enso ex Installer is a modified enso installer with extra features.

What is enso ex installer?

Enso ex Installer is a mod of enso CFW by Team Molecule adding several features to it.

Compatibility with both fw3.60 and fw3.65.
pre-nskernel recovery from a GC-SD device.
easy low-level code exec for custom kernel patches.
Ability to keep the original Playstation Boot Logo or use a custom Boot Logo/Animation.
SafeBoot system with auto-config-rebuild feature.
sd2vita driver (optional).
Update blocker (optional).
Installer - ability to skip checks (force flash).

Just run "create_vpk.sh", it will build everything and copy the package to the root directory.

If you currently have enso, make sure that it is either https://github.com/henkaku/enso or https://github.com/TheOfficialFloW/enso.
Install the VPK, run the "enso_ex" app and agree to the """ToS""".
- If you get an error, reboot the device holding LTRIGGER and try again.
Select "Install/reinstall the hack", press CROSS, the installer will install enso_ex.
- All non-critical errors can be skipped by pressing CROSS, it is safe to do so.

"os0:e2x_ckldr.skprx" will load custom modules after all base kernel modules are loaded (but not started)
It can be skipped by holding VOLDOWN at boot, custom modules load can be skipped by holding VOLUP.
To change it you need to change "ux0:eex/boot/e2x_ckldr.skprx" and sync.

Patches are *.skprx kernel modules with no imports.
Patches are located in the "ux0:eex/custom/" directory ("os0:ex/" after sync).
Patches load list is located in "ux0:eex/custom/boot_list.txt" ("os0:ex/boot_list.txt" after sync).
A list entry should be 15 characters long and have a line break (0xA) as the 16th character.
Max custom module count in boot_list.txt is 15.

e2xculogo.skprx: Use a raw RGBA 960x544 image as the bootlogo, it is located @"os0:ex/bootlogo.raw".
- In safe/update mode the PS logo is used.
- You can change it by replacing the file in "ux0:eex/custom/" and syncing.
- If the file is not found there will be no logo, useful for boot animations.
e2xhencfg.skprx:
- Adds FSELF patches allowing homebrews at boot.
- If not in safe/update mode, plaintext "ur0:tai/boot_config.txt" is used instead of "os0:psp2config.skprx".
- If SQUARE is held at boot, "ux0:eex/boot_config.txt" is used instead of the ur0: one.
  - It works in safe/update mode.

The "os0:bootmgr.e2xp" is a code blob that is executed just before psp2bootconfig load.
BootMgr can be skipped by holding VOLDOWN at boot.
To add/change it you need to add/change "ux0:eex/boot/bootmgr.e2xp" and sync.

The "recovery" is a code blob loaded from a GC-SD device in GC slot or the os0 partition.
Recovery can be loaded by holding SELECT at boot, the device must be connected to a power source.

RAW recovery (recommended)
- Use the tool in /sdrecovery/ to flash your recovery blob to the SD card.
- If the SD card contains the EMMC image you can set a flag to use its os0 for low-level modules.
- You can force it to use the FILE recovery found in GC-SD's os0.
FILE recovery
- To add a os0 recovery you need to put "recovery.e2xp" in "ux0:eex/boot/" and sync.
- To use the SD one you need to FAT16-format your SD card and put the recovery in "SD:recovery.e2xp".
- By default the device will NOT continue the boot process after this recovery method is used.
- TODO: add a cleanup sample to continue boot.

If the recovery returned 0, the console will continue the boot process.
If an error happened the user will need to confirm that he is aware of it by pressing the correct key:
- "No recovery found" - press TRIANGLE.
- "Error running recovery" - press CIRCLE.
- "Recovery did NOT return 0" - press CROSS.

You can use the SD's os0 partition instead of EMMC's os0 partition by holding START at boot.
You can also format the SD card to FAT16, holding START will mount the SD card as os0.
If an error happened the user will need to confirm that he is aware of it by pressing the correct key:
- "Error reading GC-SD" - press TRIANGLE.
- "Incorrect SD magic (not SCE/FAT16)" - press CIRCLE.

v4.5.1

Fixed the file loader, it should now detect all sizes properly.
Added a check for os0:e2x_ckldr.skprx - it will no longer bootloop if the file is not present.
It could anyways be skipped with VOLDOWN.

This is the last release for 3.60 bootloaders, all future releases will be 3.65 only.

v4.5

v4.1

Fixed FNE deadlocks - you can now delete all e2x os0 files safely.
If a low-level module fails to load it will be skipped (dex os0 doesn't bootloop anymore).
Added BootMgr (pre-psp2bcfg code exec), put the payload in ux0:eex/data/bootmgr.e2xp and sync.
Removed default enso SD read redirects (useless), for some reason GCSD FSIO speed improved significantly.
