After clearing up all the posted suggestions listed here is what worked for me
I did this (as I posted in the nook flicker thread):
I did a CAT on immediately after, and it had defaulted instead to 66461 instead of 68000 (maximum rate for the chip?)
Of course it also cleared upon reboot. Should I have seen a flicker improvement right away?
I also get 66461
------------------------
increase the refresh rate to 68000/66461 to stop/reduce flicker.
---------------------------------------------------------------------------
adb pull /system/bin/clrbootcount.sh
gedit clrbootcount.sh (assume you stay in specific dir)
add this to end of file and save
---------------------------------------------------
#run other commands
setprop persist.service.mount.umsauto 0
---------------------------------------------------
NEXT
adb shell mount -o rw,remount -t ext2 /dev/block/mmcblk0p5 /system
adb push clrbootcount.sh /system/bin/clrbootcount.sh
adb shell chmod 755 /system/bin/clrbootcount.sh
adb shell mount -o ro,remount -t ext2 /dev/block/mmcblk0p5 /system
adb shell reboot
--------------
NEXT
adb shell - NOW AT THE su # PROMPT (HAD NO LUCK WITH THE ADB SHELL and then commands all in one line)
cat /sys/devices/omapdss/display0/timings
mount -o remount,rw /dev/block/mmcblk0p5 /system
chmod 0755 /sys/devices/omapdss/display0/timings
echo 68000,1024/70/200/40,600/10/11/10 > /sys/devices/omapdss/display0/timings
mount -o ro,remount -t ext2 /dev/block/mmcblk0p5 /system
reboot
-----------------------------------------------
NEXT
cat /sys/devices/omapdss/display0/timings
66461,1024/70/200/40,600/10/11/10
----------------------------------------------
Three reboots and I still have the changes...
