scrolling lights across LED, the "knight rider" fix.

by arboristman.
first be sure your com port settings are correct:
settings for com port:
on your pc press start-control panel-performance & maintenance-system-hardware tab-device manager- ports(com1) or (whatever com port#your after)-port settings tab (in the new window)-and set your baud rate to 115200

1.Don't panic,your 2700 is not broke.

2.Prepare the unit for loading a bin file.although,this time,leave rear switch OFF.

3.Prepare the current loader,select the factory bin file (recommended,try first,but latest bin file is OK also).

3.Press download on loader,next flip the rear switch of the receiver ON.
the loader should start.
(If it does,let receiver fully reboot and read ON once again.Be sure to load latest bin file if successful,you are now finished).

4.Most commonly this will not work the first time.Try step # 3 a few more times.(if not successful continue).

5.Turn rear switch OFF,prepare loader with bin file.Quickly flip the rear switch ON,wait for FIRST light to scroll by,and press download on loader,loader should start.
(If it does,let receiver fully reboot and read ON once again.Be sure to load latest bin file if successful,you are now finished).

6.Repeat step #5 (completely)only wait for the SECOND light to scroll by,then try waiting for the THIRD light if not successful.

7. Repeat steps 5,6 until successful.Making sure the receiver reads ON and latest bin is installed on your unit when finished.

tips:
Do not give up,this WILL bring your unit to the ON condition.
It's common to take 4-8 tries.
However,it may take up to 10 tries.possibly even more,but not common.
Be sure your using the latest loader,this will work for all boot versions.
Do not try and load old b62 factory bins to a unit that has been upgraded to boot version 75.Or visa versa.

info:
nick named the "knight rider lights" or "knight rider" after the 80's tv series
"knight rider" due to the car KITT had scrolling lights across the front of it's hood.
A fairly common occurrence,likely to happen to anyone with a 2700 at least once.(to date,it's only happened once to me,while flashing)
It seems to happen most often while flashing the unit,though it does also happen while in use.
Some users may never see this,and to date is considered very minor.
