Software-based "jailbreak" allowing all ivybridge-based xx30 thinkpads to softmod custom bios images.

This repo contains the main script and pre-compiled binary files used in the 1vyrain image to flash machines.

The main link to the ready to go live USB image can be found **[here](https://n4ru.it/1vyrain/)**. *Requires a 4GB+ USB flash drive.*

Updates will be published here in the form of scripts that can be downloaded and ran on the USB image.

# Features:
- Automatic exploit chain unlocking bios region for flashing
- Model detection and automatic bios flashing
- Support for custom bios images (coreboot, skulls, heads)

# BIOS Mod Features:
- Overclocking support (37xx, 38xx, 39xx CPUs)
- Whitelist removal to use any WLAN adapter
- Advanced menu (custom fan curve, TDP, core disable, etc)
- Intel ME disablement via advanced menu

# Install

0. Ensure you're on a compatible BIOS version. Run [IVprep](https://github.com/n4ru/IVprep) if you are not.
1. Burn the 1vyrain image onto a flash drive.
2. Boot in UEFI mode from the flash drive.
3. Follow the on-screen instructions.
4. That's it!

# Custom BIOS Images
By default, 1vyrain includes the latest BIOS versions for all models, but you can flash a custom image such as heads, skulls, or a coreboot build. Make sure you have wired ethernet attached on boot, and that your image is *EXACTLY* 4MB and uploaded somewhere that you can grab with a simple `wget` command. When asked what to flash, select "Flash a custom BIOS from URL" (option 2). Input the URL. That's it!

Don't worry, if your download screws up or the filesize was wrong, the flashing will simply fail. You won't brick.

This was a monumental amount of work to put together and release, and took a lot of time. 

Special thanks goes to the r/ThinkPad discord for their efforts testing, especially \x!

Somehow we had ZERO bricks throughout the entire process! No hardware programmers were needed for recovery!
