Question

ASUS

Hello everyone, I need help, who knows how else to get around the error "Automatic System Restore Failed."?
The essence of the problem:
I want to flash ASUS DSL N10 B1 with Wive_WR-150N-RT3050-1T1R.5.2.7.RU.23092015.bin firmware
I do everything as it is written in the internet:

Step 1. Install the package of system utilities for the router on the computer.
Step 2. Specify the following parameters on the computer in the settings of the Internet Protocol TCP / IP network card: IP address - 192.168.1.2 mask - 255.255.255.0 gateway - 192.168.1.1
Step 3. Disable antivirus and firewall on the computer.
Step 4. Turn off the power of the router.
Step 5. Run the Firmware Restoration utility.
Step 5.1 In the program window that opens, press the Browse button and select the firmware file with the *.bin extension, which was unpacked in the root of the C:\ drive.
Step 6. We press the reset button on the back of the router with a pen or pencil and turn on the power.
Step 6.1 Count up to 15 and release reset.
Step 7. In the Firmware Restoration program, click the Download button.

But, constantly at the end of the "Automatic System Restore Error.", I tried it on different computers, PC and laptop, everywhere the same message "Automatic System Restore Error."
I turned off the antivirus, added the program (s) to the exception of the antivirus, so that it would not climb to it during the firmware.
One fig "Error automatic system recovery.", I don’t know how to deal with this error, please help.
