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.

# 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!
|
|
|
|
Don't be alarmed if your ThinkPad/ThinkLight power cycles a few times after a flash. That is *normal*!
|
|
|
|
**NOTE:** This will NOT modify your EC. You are safe to flash your EC with the battery or keyboard mod at any time as long as you are on a version compatible with the EC mod (check compatibility [here](https://github.com/hamishcoleman/thinkpad-ec#compatibilty-warning)). Both IVprep and 1vyrain will only modify the BIOS region! You can safely use this image to update to the latest modded BIOS without losing your EC mod!

# Custom BIOS Images
|
|
By default, the image 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!
