HifiMan HM-603 slim problem

[deadman242]

Hey Guys. I've just stupidly placed .rockbox build in step 1 listed below to internal storage of my device and followed with the instructionu:

Extract the rockbox build (rockbox-hifimanhm*.zip) on sd card of your device.
Download and install PowerISO. Free unregistered version would be enough. Or you can use any analagous program, which could edit image files with FAT filesystem.
Open OF image file (HM-601.IMG, HM-801,... ) in PowerISO? program.
Copy BASE.RKW file from SYSTEM folder in image to the .rockbox folder on sd card.
Replace BASE.RKW in OF image with bootloader.rkw (Rename booloader.rkw to BASE.RKW and replace original BASE.RKW in SYSTEM and SYSTEM00 folders).
Save changes and put derived IMG file into internal storage of your player.
Reboot your player

Currently I'm having AIA error: -4 trying to turn it on. Windows doesn't see it as usb storage anymore.

No ideas how to fix it. Please, help.

Insert sd card with proper folder .rockbox on it (should contain original BASE.RKW as well) and it should work.
