Anyone who wants to downgrade FW:
1. At first you need to flash another loader which released earler.
2. There is two types of firmware files FW96650A.bin and FWA8S711.bin
3. E.g.: after you flash loader04192013 you should use FWA8S711.bin It depends on loader not type of your DVR.
4. You can rename FW-files to take effect.
5. The best FW is DOD LS388W 1307111SC - its make special for China market ( Eng and SC languages only) but AWB is best and all features works perfect.
6. There is my July`13 FW pack - http://files.mail.ru/08D6B0CAD8DD413BBD7BFA86E803EDA1
