Installing OS 2007 hacker edition on 770 (full notes):

Note Flashable images are not available yet, we hope that we can release them during the next week.
  • Make sure that your device is running the latest official OS2006 release (we are not replacing all fiasco components, so the rest come from your old image).
  • We really recommend enabling R&D mode and disabling lifeguard reset while trying OS 2007 hacker edition. Otherwise you're likely to encounter reboot loop.
  • Install the provided kernel, initfs and rootfs images to your device using the flasher tool.

So, the steps could go as follows:
  • flasher -F SU-18_2006SE_2.2006.39-14_PR_F5_MR0_ARM.bin -f
  • flasher --enable-rd-mode --set-rd-flags=serial-console,no-lifeguard-reset
  • flasher -k zImage -n initfs.jffs2 -r rootfs.jffs2 -f

Known issues:
  • When the desktop comes up, everything seems to be frozen for 20 seconds. The same happens, if the esd crashes. Be patient
  • If you don't hear any sounds, and closing every program causes the same long freeze, try re-flashing the kernel. Your DSP haven't initialized properly and because of this esd is not working either. The reason for the freeze is discussed on this wiki page. It happened to me that I tried to flash the same image three times and sometimes it worked, sometimes not. You cannot see the difference on PC side, but if you have a serial console available, it gives you an error message.
  • osso-ias and osso-hss are currently not started (the first one segfaults and the later one doesn't initialize, currently working with that), so we don't have any touchscreen sounds and plugging a headset don't do a thing (well, kernel recognizes that).
  • Probably something more as well...
I guess it should be possible to create a FIASCO image by combining OS 2007/770 with the missing components extracted from an OS 2006 image.
