Hi trigrong,
So, your Classic is a Lite, and you have done the Reset.
But, I wonder if you have waited for the LEDs on the Classic to stop blinking before removing the jumpers from the Reset configuration.
Just to make certain, please look again at these following instructions:
"The way to do the hardware version of the factory restore (VMM)is as follows. There are 4 sets of jumpers directly above the blue terminal block. For the purpose of this we will call the left most jumper JP1 and the right most JP4 (actually labeled "Boot") •Step 1- Turn the PV and Battery power off to the Classic and remove the front cover
•Step 2- Locate the 2 jumpers JP1 and JP2. Take the actual jumpers and keep them in your hand
•Step 3- Turn the Battery power on to the classic
•Step 4- within 1 minute place jumper JP4 on its two pins and then place jumper JP1 on its two pins. at this point the 3 LEDs on the top of the circuit board should flash back and forth for about 60 seconds.
•Step 5- After the flashing stops (wait about one minute, to be sure) power down the classic and remove JP1 and JP4 and stow them back on a single pin like they where.
•Step 6- Put the front cover on and power up the Classic Lite (or Classic). If you have the MNLP set to Custom you will need to go to the local app and reset the battery voltage and setpoints etc."
I needed to do the jumper Reset on two Classics, and I did not wait long enough when first trying to do the reset, so ...
NOTE: When doing the Jumper Reset, you MUST WAIT for the LEDs on the Classic main board to STOP blinking -- previously, I gave up too soon, and guess that all of the Resetting was not complete. (this wait interval was not actually defined in Erik's posted info from boB - IMO). One Classic reset took about 45 seconds, the other about 38 seconds, by my count.
AND, there IS a lot of customized data that must re-entered into the Classics to return them from the Factory Defaults.
Just to try to make sure that the full reset has taken place before removing jumpers.
YES, it is very troubling when an Update fails, and you cannot go back to the original firmware.
Good Luck, Vic
