How do I reflash my tablet?

[SuperWind]

I have the recovery image for it but not sure what to do, I dont wanna do it via fastboot because it wont work(it wont show up my device when using fastboot device plus it always say waiting for device) so i heard you can do it with adb shell but how.

Using ADB shell, you could place the image file on the SD card or internal memory and use the dd command. I'm not sure so PLEASE DO NOT JUST USE THIS COMMAND, but I think recovery is /dev/block/mtdblock4, so it would be something like dd if=/mnt/sdcard/yourNewRecovery.img of=/dev/block/mtdblock4 bs=512.
