You should try to find the exact cause of the error. It could be due to a corrupted os-area. > 2) My Date time is not correct.

I don't want to modify source for my one > rtc time problem? Your problem is that the os-area database value is wrong and is not being set. The RTC hardware of the PS3 cannot be reset, so each OS (game-os and Linux) needs to maintain a difference between the hardware RTC value and the value it uses for time. A read-only copy of the game-os diff is put at os_area_params.rtc_diff. You can read that with 'ps3-flash-util --game-time'. For Linux we keep that difference in the os-area database (db_area_offset + OS_AREA_DB_OWNER_LINUX + OS_AREA_DB_KEY_RTC_DIFF). See: https://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-linux-docs/PlatformSpecificUtilities.html First you should try to set the os-area value with 'ps3-rtc-init --force'. Look at the ps3-rtc-init source to see how to set the rtc diff value yourself: https://git.kernel.org/pub/scm/linux/kernel/git/geoff/ps3-utils.git/tree/ps3-rtc-init.in#n69 Maybe you need to re-format the os-area database 'ps3-flash-util ----db-format'. Make a backup first. See '** backup flash data **' here: https://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-howto/ps3-boot-recovery-howto.txt -Geoff
