I have this tablet that runs on RK3168 (Rockchip) SoC. The problem is that fastboot doesn't recognize the device, but after so much toil, I managed to find Finless' flashing tool and flashed CM Recovery image unto the device. The flashing worked because when I rebooted to recovery mode, it showed CM recovery screen instead of the stock recovery screen.
The flashing tool is a windows GUI. It doesn't have an unlock bootloader function. But since I was able to flash the recovery image successfully, my question is, does this mean that my device bootloader is already unlocked?
Edit: (more details) Using Finless' flashing tool, I backed up all the NAND partitions and named them accordingly, e.g. backup.img, kernel.img, etc. Then I reflashed them all back into the device but reflashed a different recovery.img. I reflashed a generic CM that I got from this site instead: http://androtab.info/clockworkmod/rockchip/
I did all this with the assumption that the flashing tool actually works. After all, I used it to make the backup as it was the only tool that detected the device in fastboot mode because fastboot just doesn't detect it. (It could be that the bootloader interface driver doesn't work properly for fastboot on Win x64, but I don't have the luxury of setting up a 32-bit OS.)
When I rebooted the device, everything was fine. Rebooted into recovery mode and CM recovery screen showed up.
I'm still new to all this android flashing stuff, I don't really know what an unlocked bootloader means, and I just read from other guides that in order to flash a custom recovery, I need an unlocked bootloader first. So I'm presuming that if I was able to flash images, that my bootloader is already unlocked? But I'm not sure, so that's why I'm asking (albeit a very naive question...)
