I just succeeded doing the CF-mod on my rockboxed iHP-120!
What did I do on my iHP-120:
(0. Order the CF-to-IDE-adapter => ebay)
1. install the latest H120 rockbox-build from today
2. download the necessary "7pre4"-bootloader for the H120 here:
http://www.rockbox.org/twiki/bin/viewfile/Main/IriverFlashing?rev=1;filename=bootloader_h120_7pre4.zip3. copy the "7pre4"-bootloader to your H120´s harddisk(root directory)
4. FLASHING:
First Initialize your player as follows: (Stop audio playback).
Set "Show Files" to "All" in General Settings.
Enter the File Browser through the Files entry in the Rockbox menu.
Then I navigated to "bootloader.iriver".
I placed the cursor over "bootloader.iriver" and LONG pressed joystick, (navi), then I selected "Open with...".
From the list of plugins, select iriver_flash and execute.
If the requirements are met, a confirmation message is displayed,
Press PLAY to confirm, the firmware flashing starts, (rockbox now overwrites iriver firmware).
If everything went fine, you should see, "Success" and the player will return to the file browser.
5. Copy the complete rockbox directory to your PC
6. Put your CF-card into the iriver by using the CF-to-IDE Adapter mentioned in this thread on page 1.
7. Bend down the adpater´s jumper, otherwise you´ll run into issues later on
8. Copy the folder from your PC back to the CF-card
9. Fix the 8 torx screws and you are DONE!
I use a SANDISK 8GB extreme III CF-card, which has ONLY 133x speed(about 20MB/s read and write).
No errors on boot-screen.
NO SOUNDS of my former harddisk anymore too HAHA!
System/Rockbox-Info shows 7.xx GB as supposed to.
here some pics from my "challenge":
My 8GB CF card put into the ebay-Honkong-"CF-to-IDE adapter" : You can see how I needed to bend down the blue jumper.
