I tried to install Coolreader but I get a «*The device is not registered as a Test Kindle to run this title. Please ask the developer to add this device to the list of registered Test Kindles.*» message.
I tried to add the developper keys as suggested in one post, it doesn't work (I rebooted).
I tried to follow that, too, same issue: https://www.mobileread.com/forums/sho...&postcount=136
I'll try to use kite tomorrow, good night.
