## Electra Setup
* Jailbreak your iOS 11.0 - 11.1.2 device with Electra >= b7
* Jailbreak your iOS 11.0 - 11.4.1 device with Electra >= 1.3.2
* Copy the bfinject tarball, https://github.com/BishopFox/bfinject/raw/master/bfinject.tar, onto your jailbroken device. You might need to copy it to your laptop first because Github enforces SSL, but the Electra version of `wget` doesn't support SSL.
```
ssh root@your-device-ip # (the password is 'alpine')
ln -s /electra /bootstrap # (latest Electra path move to /electra)
mkdir /bootstrap/usr
mkdir /bootstrap/usr/local
mkdir /bootstrap/usr/local/bin
mkdir bfinject
cd bfinject
wget http://<your_server>/bfinject.tar
tar xvf bfinject.tar
```

## LiberiOS Setup
* Jailbreak your iOS 11.0 - 11.1.2 device with LiberiOS >= 11.0.3
* Jailbreak your iOS 11.0 - 11.4.1 device with LiberiOS >= 11.0.3
* Copy the bfinject tarball, https://github.com/BishopFox/bfinject/raw/master/bfinject.tar, onto your jailbroken device. You might need to copy it to your laptop first because Github enforces SSL, but the LiberiOS version of `wget` doesn't support SSL.
