Firmware
If your DVR is working fine it is not recommended to upgrade the firmware. Firmware is created based on the chipsets of the mainboard. In the process of loading firmware, and you are having problems it is recommended that you do not perform a hardware reset. Firmware upgrades are only to be performed by a qualified tech due to various mainboard versions, and chipset version. A firmware upgrade will not solve technical difficulties on the most part. If a DVR is having a problems most likely the problem will continue after a firmware upgrade. Proper trouble shooting will be required to see if a firmware will resolve the problem.

H.264 models will see a rapid turnover in firmware releases, and it is recommended to keep up to date with your model version.

Tech Support
The distributor is responcible for techsupport issues, and tech support personal, and should not be elevated to the manufacture level. It is recommended to avoid distributors that do not have a techsupport division, and to avoid non authorized AVTech distributors.

Hardware reset
Prior to doing a hardware reset proper troubleshooting is recommended to verify that you do not have a hard drive failure, a external power supply, or an internal power supply problem.

A hardware reset can be perfomed by following the model version PDF. Most DVRs will have two pins labled JP2, or they may have to pads to perform the hardware reset.
