iPod Classic 6G (80GB, A1238) Rockbox bootloader not loading issue fixed!!
Device info
iPod Classic 6th generation (model A1238, 80GB). Original Apple firmware 1.1.1. Windows 10.
Problem:
The bootloader installation (both via Rockbox Utility 1.5.1 and manual mks5lboot dual-boot) always reported success. The .rockbox folder was present, and I even created bootloader.cfg / emcore.cfg with default=rockbox in the root and in .rockbox. However, the iPod still only booted the original Apple firmware. No fallback image ever appeared, no matter which button I held (Select, Play/Pause, etc.). The DFU flash output showed "DFU image sent successfully", but the bootloader never took control on reboot.
What didn't work:
-Rockbox Utility 1.5.1 automated installation multiple times, both with and without prior bootloader.cfg/emcore.cfg files.
-Manual mks5lboot64.exe(dual-boot) same result.
-Placing bootloader config files in root, in .rockbox, or deleting them entirely.
-All known button-hold combinations to trigger boot menu or fallback image.
-Ensuring Disk Mode, DFU mode, different cables, different USB ports, admin privileges.
What finally worked:
-Using the single‑boot method with mks5lboot64.exe. This overwrites the Apple firmware so the iPod boots directly into Rockbox.
Step‑by‑step
1-Downloaded the Windows binaries ZIP from freemyipod.org. This package includes mks5lboot64.exe and bootloader-ipod6g.ipod in one folder.
2-Put the iPod into DFU mode: connected it to the PC, held Menu+Select for ~30 seconds until screen went black and Windows made a USB connection sound.
3-Opened Command Prompt in that folder (typed cmd in File Explorer's address bar).
4-Ran: mks5lboot64.exe --bl-inst bootloader-ipod6g.ipod --single
5-Output confirmed: [INFO] DFU image sent successfully (110480 bytes).
6-Disconnected the iPod and hard‑reset (Menu+Select). The Rockbox logo appeared immediately, and Rockbox booted.
7-(Had already manually placed the .rockbox folder from the stable 4.0 build on the iPod's drive – that's essential after flashing.)
Important caveats:
The --single flag permanently removes the ability to boot the original Apple firmware. If the flash fails, the iPod becomes unbootable and must be restored via iTunes in DFU mode. Try this at your own risk.
A few users have reported that even single‑boot fails on some hardware; there's no 100% guarantee. But for me, it was the only thing that worked after dozens of dual‑boot attempts.
The firmware version 1.1.1 is compatible; I did not need to upgrade to 2.0.4.
Hope this helps someone else facing the same stubborn Classic. Thanks to the community for the documentation that made this possible.
