First, sorry about bad english.
N810 with CSSU stable and Diablo Turbo installed.
Yesterday installed bootmenu to boot the system from a memory card.
Card properly partitioned and rootfs copied to ext2 mmcblk1p2
After command "# chroot /mnt/initfs cal-tool --set-root-device ask" bootmenu's menu appears but boot from sd fails because i forgot to make bootmenu.conf in /etc
I created bootmenu.conf and reinstall bootmenu from shortcut "install bootmenu".
Menu doesn't appears now, "# chroot /mnt/initfs cal-tool --set-root-device ask" and "press and hold menu button" doesn't works.
Device booting to flash always, just showing "press and hold" message.
Tryed to reinstall initfs with "sudo flasher-3.5 -F RX-44_DIABLO_5.2008.43-7_PR_COMBINED_MR0_ARM.bin --flash-only=initfs -R"
But flasher output is:
"USB device found found at bus 001, device address 007.
Found device RX-44, hardware revision 0805
NOLO version 1.1.16
Version of 'sw-release': RX-34+RX-44+RX-48_DIABLO_5.2010.33-1_PR_MR0"

How to resolve this problem?
Maybe some bootmenu log or something for understanding whats wrong?

Okay, old version of bootmenu working properly on n810.
