How To: Install Windows on Raspberry Pi with Linux/macOS/Unix (WoR)

Wondering how to create a Windows 10 on ARM (Windows on Rapsberry Pi) SD Card from a macOS or Linux/Unix computer? Using a free minimal Windows 10 Virtual Machine image and the open source software Virtual Box you can pass your SD Card or USB Drive the Windows on Raspberry (WoR) media creation tool! This easy guide will show you how

Requirements: SD Card Reader/USB Drive, ~20GB Free hard drive space on the host machine to download and Extract the Windows 10 VM and download an ARM64 disk image of Windows 10 for installation.

1. Download and Install Virtual Box

How To: Reverse Engineer Any Private API (iOS/Android and Desktop)

Have you ever wanted to access data from an application that doesn’t provide a Public API? Well I’ve got great news. That application is getting its data from somewhere. You just need to find out how to plug into it! This process is called Reverse Engineering (Or hacking if you want to pretend you’re really smart) a Private API. I will document some tips and useful tools that will help you reverse any Private API from any application on any platform.

Reverse Engineer any Private API – Watch the YouTube video here! https://youtu.be/RchCi6E2hVs

Tools

There are a hanful of tools that can be used to complete this task. Windows 10 was my platform of choice for working with the data so I’ll be sharing what I used on here.

Fiddler: Fiddler is an HTTP/HTTPS Proxy that can be used to intercept and decrypt SSL/HTTPS traffic. This application is also useful for replaying requests, creating custom request, and exporting a request as cURL to be converted into Python 3. Fiddler is free to use, just sign in with your Google Account! Make sure you install the certificate and enable HTTPS mode so you don’t miss any requests. https://www.telerik.com/fiddler

MitM Proxy: Man in the Middle Proxy is a great way to read data from Smart Phone Applications. This is what I used to get all the data I needed for my API reversal. Simply download the executable from https://mitmproxy.org/ to start up a server (disable your firewall or open port 8080) and then enter your PC’s IP address into the Proxy Server settings of your Phones WiFi settings. After that navigate to http://mitm.it/ on your Phone and install the provided certificate. Follow the provided instructions on http://mitm.it/ and start sniffing!

Tips

Create a text document to save all your finding and especially any useful URL endpoints you find. Having your information organized will help to ensure that you don’t waste time on the same thing twice or need to proxy your device over and over again to find what a request should look like.

Update to PHP 7.4 with Redis on Apache2 Ubuntu 16.04/18.04/20.04

PHP 7.4 is recommended to use used by WordPress. In this guide the simple to use commands will be layed out one by one for easy copy and pasting to your Ubuntu VPS/Server.

First update/sync your repositories and make sure you have redis-server and php7.4 installed

next disable php7.3/php7.2 and enable php7.4 (substitute for your currently used php version)

sudo a2dismod php7.3
sudo a2enmod php7.4

Install common php7.4 modules. You may skip this step if you know exactly what modules you need.

sudo apt install php7.4-dom php7.4-common php7.4-mysql php7.4-xml php7.4-xmlrpc php7.4-curl php7.4-gd php7.4-imagick php7.4-cli php7.4-dev php7.4-imap php7.4-mbstring php7.4-opcache php7.4-soap php7.4-zip php7.4-intl -y

Install php-redis and enable the module

sudo apt install php-redis
sudo phpenmod -v 7.4 -s ALL redis

restart the apache2 service

sudo service apache2 restart

Jailbreak iOS device with Android Phone – One Tap checkra1n TWRP App

Download on GitHub: checkra1n TWRP: Jailbreak iOS with Android

Long time no see iOS/Android enthusiasts. I wanted to share a useful app I created to automated the process of running checkra1n for arm64 (Android Phone/Tablet) in TWRP (Team Win Recovery Project). This is a fully open source program (excluding the checkra1n binary) licensed under Zero Clause BSD. View it on GitHub here.

TWRP has a built in functionality to queue commands for the next recovery boot. These commands are located in /cache/recovery/command which is just a text file that TWRP reads. This is the same functionality that allows Over The Air (OTA) updates for custom ROMs to boot and reflash themselves.

Using this queue system the checkra1n TWRP app copies an Open Recovery Script (flashable .zip) to /data/checkra1n/checkra1n.zip and boots to recovery by invoking reboot recovery. The included checkra1n.zip then executes and boots back to system reboot system after the checkra1n log message of [*]: All Done is received.

This will not increase the comparability of checkra1n for Android devices but my 2015 Nexus 5X and 2018 Mi Mix 3 both run this application flawlessly. If you were already using your Android device to run checkra1n this should make things easier for you as you don’t need to interact with a shell at all on invoke/remember commands.

To flash the .zip within TWRP without running the app, which is useful if you leave your Android turned off until you need it for a retether, you can find the flashable Open Recovery Script in /data/checkra1n/ and flash it from the Install menu within TWRP.

Happy jailbreaking! (please report bugs on the Github Bug Tracker)

Edit: Removed from Google Play for TOS https://github.com/downthecrop/checkra1n-twrp/issues/3

If you would rather run the binary directly you can follow my old guide here: https://downthecrop.xyz/blog/jailbreak-ios-device-with-android-phone-checkra1n-for-android-tutorial/

Jailbreak iOS device with Android Phone – checkra1n for Android Tutorial

How to run checkra1n on Android to jailbreak iOS – Watch my video guide here!

Edit : 9/9/2020 I’ve made an app to easily run the required commands! Check out my updated guide here: https://downthecrop.xyz/blog/jailbreak-ios-device-with-android-phone-checkra1n-twrp-app/

Did you know you can use an Android Phone to jailbreak iOS using checkra1n? Here’s the step by step guide and tutorial to explain how to run checkra1n on Android.

  • Rooted Android device
  • USB-C to USB-A Adapter
  • Lightning cable
  • TWRP Custom Recovery

When you have gathered the supplies navigate to the official checkra1n website and download the lastest arm64 Linux binary of checkra1n

https://checkra.in/

Note the location you downloaded the file to. You will need to know the absolute path the file is located so you can execute it from a terminal command line.

Once you have the file downloaded boot your Android phone into Custom Recovery. Running the tool from Custom Recovery instead of directly inside Android you don’t need to worry about a conflict between different processes fighting over the USB controller. I wasn’t able to run checkra1n from a fully booted Android 10 but I was able to run it from Custom Recovery! Your luck may vary but Custom Recovery is the most reliable option.

Open a Terminal in Custom Recovery (TWRP 3.3.1-17 was used in my video) and change directory to where you saved checkra1n

cd /sdcard/Download

Next we need to add the execute flag to the binary so it can be run as a program

chmod +x checkra1n

Finally we can run checkra1n from Android

./checkra1n -c -v

Connect your iOS device using your USB-C to USB-A adapter and your Lightning cable.

Now we need to manually enter DFU mode on our iOS device. This is done differently on different devices so if you are unsure just look up “How to put iPhone X into DFU mode” replacing iPhone X with your model and you should find some button combinations to enter DFU.

If you have successfully put your iOS device into DFU and it is connected to your Android Phone running checkra1n the program should recognize the DFU mode USB device and run the exploit!
