@Booxtor thanks for sharing the specs! Onyx Int. sales is reluctant to release factory tools / firmware images for readers with Snow Field support. Do you happen to know when it might become available for users who have bricked devices?
@downeaster59 according to the Russian distributor, Carta+ / Carta2+ readers support Snow Field waveform technology which is an attempt to reduce ghosting for rockchip devices - just what Regal does for Freescale readers (
E Ink Carta specs sheet).
When Snow Field is enabled in OReader and Onyx Neo Reader 2, the screen refreshes with every page turn, but the screen is not filled with black, so there's no "blinking" any more. White pixels remain white, black pixels disappear (turn white), gray pixels first turn black and then disappear. 3rd-party apps won't have SF support
