Hello to all.
First, sorry for my bad english, I'am Portuguese.
Next, i have a problem with a 4channel dvr, Konig SEC-DVR210, which blocked at boot after a failed firmware update. On the web I found this great forum and so I come here asking for help.
I as said the device blocked at boot after a failed upgrade, certainly with the bootloader damaged, giving just a constant and annoying beep.
Although the brand of device is KONIG the board is a Japanese manufacturer, model JESMAY 3604, and has only one JTAG port not having serial port. "photos of board attached"
so, I need to unlock the boot by jtag, this has an ARM7 processor AT91R40008, and a flash 39VF800A.
I want to know if someone gains access to the bootloader of these devices and connection information for jtag, because I can not get any response from manufacturers.
Any help will be greatly appreciated and will be grateful.
Thank you in advance
