structure of firmware image/flash rom and USB flashing protocol should be basically same from RK28 ages(from users' PoV). there are some amount of experiences. some open source tools such as rkflash/rkflashtool can do some work for RK3188 too. it's possible. all you need is 'don't use MEMERASE ioctl, use bs=16384'. if you need working flash_image command, you can get it from my site, http://androtab.info/clockworkmod/rockchip/ there are 2 modes for USB communication. mask rom mode, like as FEL mode on sunxi, bootloader needs to be loaded by rockchip official tools such as RKAndroidTool, RKBatchTool, etc. rkflash/rkflashtool doesn't support this mode yet. bootloader mode, bootloader(currently made by rockchip only) is loaded from flash or USB, it should be possible to read/write RAM, NAND and IDB(bootloader) via USB. rkflashtool can read/write NAND and can read RAM/IDB for now. if you don't touch bootloader, rkflashtool works nicely for kernel/userland development. there are a lot of rkflashtool forks, but this one should be better, https://github.com/crewrktablets/rkflashtools
