Xiegu X6100 SD Card Creation Tool (Rufus 3.10p)
==============================================

WHAT THIS IS
------------
The "SD Card Creation Tool" offered on xiegu.eu for the X6100: "Tool to
create SD card with FW updates for Xiegu X6100." It is the portable build
of Rufus 3.10 (file version 3.10.1647, (C) 2011-2020 Pete Batard, GPL v3)
with a small rufus.ini. The same two files are in the sd_tool/ (or
Tools/) folder of Xiegu's X6100 firmware packages from December 2021 to
August 2023.

The rufus.ini sets "UpdateCheckInterval = -1", which turns off Rufus's
online update check, and sets the locale to en-US.

Rufus writes a disk image (the X6100's x6100udimg*.img / sdcard.img) to a
microSD card. It does not contain firmware. Only one version of this tool
was published by Xiegu.

APPLIES TO
----------
Windows PCs preparing X6100 firmware cards. Xiegu's tutorial names Windows
7 and 10. The tool itself is generic and writes any disk image, including
the R1CBU alternative-firmware images.

BEFORE STARTING
---------------
- An X6100 firmware package, unzipped (the .img file is needed).
- A microSD card of at least 4 GB and a card reader. Everything on the
  card is erased.
- Administrator rights (Rufus asks for elevation).

INSTALLATION
------------
Nothing is installed. From Xiegu's X6100 Firmware Upgrade Tutorial V1.1:
 1. Unzip, run rufus-3.10p.exe and click "Yes" at the administrator
    prompt. Keep rufus.ini in the same folder.
 2. Device: select the card reader's drive letter. Boot selection: "Disk
    or ISO image". Rufus normally detects both; check them.
 3. Click SELECT and choose the firmware .img file.
 4. Click START; click "OK" in any dialog box.
 5. At 100 %, click CLOSE. Eject the card reader through the operating
    system before removing the card.
Then continue with the firmware package's own instructions.

VERIFYING
---------
Rufus's progress reaches 100 % when writing has completed (Xiegu
tutorial). On the radio, the update starts by itself when the card is
inserted and the radio is switched on.

IF SOMETHING GOES WRONG
-----------------------
- Wrong drive in the Device list: stop. Rufus erases whatever is
  selected. Remove other USB storage and select again.
- The radio does not start the update: re-write the card, and eject it
  properly before removal (Xiegu warns that pulling the reader out
  directly can damage the files on the card).
- Current Windows versions or other image writers: Radioddity's current
  instructions use the current Rufus from https://rufus.ie/ on Windows
  7/10/11, or balenaEtcher on Linux and macOS; either works in place of
  this 2020 build.
