- added signed ADB driver for Windows x86/x64 (tested on Win 8 Pro x64)
- zipaligned a few stray APKs
- root (Superuser)
- adb root (ro.secure=0 in default.prop, adb remount possible)
- CIFS/SMB support (load /system/lib/modules/slow-work.ko before /system/lib/modules/cifs.ko for it to work) - pilfered from MalaRom - thanks Mala!
- added /system/bin/flash_image (for flashing recovery.img etc. via adb shell or terminal emulator)
- some build.prop tweaks (boot animation disabled, so don't freak out when the screen stays blank for a while)
- Cowon bloatware removed (Kakaotalk, JetVD, Twitter, about a dozen ugly clock widgets, etc.)
- Google Play Store included
- Titanium Backup (free version) included
- new default wallpaper in framework-res.apk
Unpack the update.zip from the Cowon_D3_v3.55-xxxxxxxx-DFKT.zip and put it on /sdcard/ or /sdcard/tflash. Flash the update.zip in stock recovery (hold play button while powering on, then at the triangle screen press the home soft button). If you came from stock v3.55 you don't have to wipe anything - at least I didn't, and my D3 runs fine.
After you installed the custom ROM you can install CWM Recovery via flash_image, either in adb shell or in a terminal emulator. Unpack the recovery.img from Cowon_D3_CWM_Recovery_x.x.x.x_flash_image-DFKT.zip and put it on the /sdcard/. Flash it in adb shell with adb shell flash_image recovery /sdcard/recovery.img or in terminal emulator with su, then flash_image recovery /sdcard/recovery.img.
CWM Recovery can't deal with the NTFS-formatted internal storage, so all the backups go to the external SD card, on /sdcard/tflash. Same goes for flashing update.zips with CWM - you have to put them on /sdcard/tflash for CWM to find them.
I built this CWM Recovery from the Cyanogenmod ICS branch, so it's not the very newest version, but it's good enough.
If for some reason you want to go back to stock recovery, I prepared a recovery.img for that case too - flash it the same way as CWM Recovery.
