The most important of all, before you start to read this guide, make sure you have the ability to handle the problem you meet. You are fully doing this at your own risk, I’m not responsible for any damage caused.

If you don’t know what this article is doing, you can download the released ipa on the author website resign by tools such as iResign and install it to your iPhone without building it youself.

Advantage of build the toolkit yourself

1. Know the structure of the code
2. Preventing if there were malicious code in toolkit.
3. Remove unused features. For example, in this toolkit, it will install Anemone tweak after you jailbreak. The last part in this tutorial will told you how to do it.
4. Keep the latest version, you can pull the latest version from Github and build it yourself.
5. You need to turn the SIP off of macOS before you did these instructions.

Clone repo

You can access the Electra repo on Github, which contain a Xcode project.
Clone it to your ~/Desktop or any other path you like to work with.

git clone https://github.com/coolstar/electra.git

Build Xcode project

Open the Xcode project then build. You will meet some error with the clean Xcode environment.

ldid2 error

After you build the project, you will meet a error. You will see this error:

At the first test, I tried install ldid original version by

brew install ldid

and the bin of the ldid would be at /usr/local/Cellar/ldid/1.2.1, then link it as ldid2 in /usr/local/bin

ln -s /usr/local/Cellar/ldid/1.2.1/bin/ldid /usr/local/bin/ldid2

With the ldid, it can work, and you can build the toolkit into your iPhone. However, the jailbreak won’t success and block on 2/3.

So I tried to find the solution on Github. I found xerub make a ldid2 with SHA256 support. However, this repo is not complete. The repo are lack of make code and wasn’t build.

Add ldid2 to /usr/local/bin/

I completed the ldid2 project and put the binary in release version page.
Project Link

curl https://raw.githubusercontent.com/GaryniL/ldid/master/ldid2 -o ldid2
sudo mv ldid2 /usr/local/bin/
chmod +x /usr/local/bin/ldid2

Then rebuild the project, it will work.

Remove Anemone

Besides, you can remove the line for preventing installing Anemone tweak
