1) removed the battery and put it back, by pressing power + volume down to boot into recovery, if successful then flashed 23 or 25 Rom. If can't go into recovery, the only way was by sp flashtool. You have to install the correct driver on the windows PC. Here is the link for the drivers:

Unzipped it and you have three folder, just open All MTK Drivers folder > New inst. win 7&8x64 and run DPInst64.exe for 64 bit windows or run dpinst.exe for Windows 32 or older machine. On windows 8 you need to disabled driver verification. Once the driver successfully installed, follow sp flashtool in the op to downloading the scatter file strictly fellow the instructions. Once finished put back the battery and reboot, and flashed the new rom 23 onward or the latest miui_H3WGlobal_JHDMIBE25.0_8c0bc29f06_4.2.zip. I had successfully unbricked my friend's hm note 1w. Hope it help. Enjoy.
