# Officially, this is not recommended. YMMV

# This mostly works if you are on 64bit. You are on your own if you are on 32bit or mixed 64/32bit

Downgrade and dualboot status of almost all iOS devices

UPDATED: 2024-09-25

• Reddit mirror: https://www.reddit.com/r/iOSDowngrade/comments/j1x7iv/downgrade_and_dualboot_status_of_almost_all_ios/
• GitHub Gist mirror: https://gist.github.com/LukeZGD/9d781f1b03a69fa46869384a9407a41a
• As of updating this post, there is a downgrade tool that utilizes a SEP exploit released. However its device support is currently limited: https://limefix.tech/?product=limefix-sep-utility-testing
• Save SHSH blobs for signed iOS versions using TSS Saver or blobsaver
• GitHub repo for futurerestore nightly: https://github.com/futurerestore/futurerestore
• For Windows builds of futurerestore, go to the Discord server linked in the readme

# This file contains pin mappings for the stock 2020 Creality Ender 3
# V2. To use this config, during "make menuconfig" select the
# STM32F103 with a "28KiB bootloader" and with "Use USB for
# communication" disabled.

# If you prefer a direct serial connection, in "make menuconfig"
# select "Enable extra low-level configuration options" and select the
# USART3 serial port, which is broken out on the 10 pin IDC cable used
# for the LCD module as follows:
# 3: Tx, 4: Rx, 9: GND, 10: VCC

Upload Large Files with Dropbox v2

To upload large files with Dropbox, you need to use upload sessions.

The utility function below can be used for this purpose.

It uses the Dropbox Python SDK to upload the local file specified as file_path to the remote path specified by dest_path. It also chooses whether or not to use an upload session based on the size of the file.

# This file contains pin mappings for the Creality Ender 5 Plus.
# Ender 5 Plus stock uses a Creality v2.2 board, similar to CR-20 Pro.
# To use this config, the firmware should be compiled for the AVR atmega2560.

# See the example.cfg file for a description of available parameters.
