Install Rockbox using RockboxUtility or + download the latest daily build and uncompress it into the root folder + of the iPod. + + Windows only: + + - If iTunes is installed: + . Configure iTunes: Summary -> Options -> check "Enable disk use". + + - If iTunes is not installed: + . You need a DFU USB driver for your device. To check if there is a + valid USB driver installed, put your device on DFU mode and choose + one of either: + a) Use Windows Device Manager to verify if you USB DFU device is + present. + b) Use mks5lboot tool running "mks5lboot --dfuscan", common output: + . When the DFU device is found and a valid driver is installed: + [INFO] DFU device state: 2 + . When the device is found but there is no driver installed: + [ERR] Could not open USB device: LIBUSB_ERROR_NOT_SUPPORTED + . Then the device is found but driver is not valid (probably a + libusb-win32 driver is installed): + [ERR] Could not set USB configuration: LIBUSB_ERROR_NOT_FOUND + . If there is no valid DFU driver installed, try one of these: + a) Use Zadig (http://zadig.akeo.ie/) to build and install a WinUSB + (libusb.info) or libusbK driver for your device. Note that + libusb-win32 (libusb0) drivers are not valid for mks5lboot. + b) Use Apple Mobile Device USB driver (included with iTunes). + +Command line install: + + - If you are using iTunes on Windows, close iTunes and kill (or pause) + iTunesHelper.exe before entering DFU mode. + + - Put you device on DFU mode by pressing and holding SELECT+MENU buttons + for about 12 seconds. + + You can notice when the device enters DFU mode running the next command + to scan the USB bus every second (press Ctrl-C to abort the scan): + mks5lboot --dfuscan --loop + + - To install or update a bootloader, build the DFU installer and send it + to the device: + mks5lboot --bl-inst /path/to/bootloader-ipod6g.ipod + + When the DFU imagen is loaded and executed, the device emits an 'alive' + tone (2000Hz/100ms). When the bootloader is successfully installed then + a dual tone beep sounds (1000Hz/100ms+2000Hz/150ms) and the device + reboots. If something went bad then 330Hz/500ms tone is emited and the + device reboots. When three 330Hz tones sounds, it means that the NOR + got corrupted and the device must be restored using iTunes (should not + happen). + + - To remove a previously installed bootloader, build the DFU uninstaler + and send it to the device: + mks5lboot --bl-uninst ipod6g + + If USB access is denied, try to run the mks5lboot tool using a privileged + user (i.e. Administrator or root). + + +Dual-Boot +--------- + +The purpose of this program is to provide dual-boot between the original +firmware and the new (rockbox) firmware. + +The button press check is done ~800 ms. after power-up or reboot, then: + + SELECT + MENU: resets the device after ~5 seconds, then if SELECT+MENU + remains pressed the device enters DFU mode after an + additional period of ~8 seconds. + SELECT + LEFT: enter OF diagnostics (after ~7 seconds). + SELECT + PLAY: enter OF diskmode (after ~7 seconds). + SELECT + RIGHT: enter bootloader USB mode. + MENU: enter OF + Hold Switch locked: enter OF (see below for details). + Any other combination: launch Rockbox. + +Switch current firmware: + + Tries to behave like ipod Video, see http://download.rockbox.org/manual/ + rockbox-ipodvideo/rockbox-buildch3.html#x5-290003.1.3 + + Apple is the current FW: + - Stop playback and wait a few seconds for hard disk spin-down. + - Press and hold SELECT+MENU, after ~5 seconds the player hard resets, + release the buttons when the screen goes black. + + Rockbox is the current FW: + - Shut down the device using "Long Play" key press. + - Once the device is powered off, there are three ways to enter OF: + 1) Press and hold MENU button for at least ~800 ms. + 2) Turn on the Hold switch immediately after turning the player on, + it must be done before "Loading Rockbox..." message appears (~3 + seconds from power-on). Be careful, if the hold switch is locked + when Rockbox starts then your RB settings will be cleared! + 3) You can also load the original firmware by shutting down the + device, then clicking the Hold switch on and connecting the iPod + to your computer. + + +Single-Boot +----------- + +Use --single option if the Apple firmware is not installed on your iPod +and/or you want to force the installation of the bootloader to use Rockbox +as unique firmware. The single-boot installer writes the bootloader on the +NOR with no previous check, the original Apple NOR boot is destroyed if it +exists. + +To build the DFU single-boot installer and send it to the device: + mks5lboot --bl-inst --single /path/to/bootloader-ipod6g.ipod + + +Compilation +----------- + +Needs libusb > 1.0 installed, tested on: + +Linux: gcc-4.9.2 + libusb-1.0.19 +Windows XP: mingw32-gcc-4.8.1 + libusbx-1.0.15 +OS X 10.11: clang-7.3.0 + libusb-1.0.20 + + +Hacking +------- + +See comments in mkdfu.c, ipoddfu.c, dualboot.c and bootloader/ipod6g.c for +more information. -- cgit v1.2.3
