Oh no! So near but so far. I was expecting a .IMG file that I could flash with Rockchip Batch Tool. Instead this is a .ZIP update package. My tablet is in MASK ROM mode (dark blue square in batch tool upon connection) and I'm a little lost. I have dumped the entire NAND off of another of these tablets that I had and tried to flash that with RKAndroid Tool 1.37 but get a failure when I press start which says "MaskRom device must choose loader for upgrading". So I figure bootloader is screwed. I have a selection of rockchip bootloaders downloaded so choose "RK30xxLoader(L)_V1.11.bin". Flashing then begins but fails with "error:download IDB failed" after a few seconds.
Any ideas, hoping you might have some insight through your previous dealings?
