Firmware upgrade 2.90 -> 3.13 does not work. Downgrade?

[Boris]

Hi!

I followed the FAQ for the 3.13 upgrade on my OSTC 2C (from v2.90):
1) upgrade firmware
2) charge for 30 hours (minimum)

But after 2 tries of installing the firmware and 40 hours of charging the battery symbol is still blinking and the battery symbol shows only a few (5) pixles of charge. So the battery is basically empty. What did I do wrong? How can I fix it?

Well, I want to downgrade to the previous but working version 2.90 (which is the initial version on my OSTC). Where can I download it? The website gives me the latest version only.

Thanks in advance,
Boris

Did you reset the battery timer?

The problem has been solved. An early version of the FAQ said that CF74 should have the value 1800 (30 hours). Well, the value "Default" was set to 1800, but the value "Current" was set to 0. After setting "Current" to 1800 everything was fine.
Thanks to HW for solving (my) problem.

Default is a fixed value and can't be changed.
