try to use other psu … at lest 12V1A

Still the same problem can anyone help me …?
plsssssssssssssssss…

It’s rebooting every few seconds? What’s setup in your watchdog entry?

Instead of trying to upgrade/downgrade, reset the unit back to defaults and try programming it again. Sounds like it’s an errant configuration (or a power supply issue like vacarosie200 mentions) more than a firmware problem.

How did you upgrade your firmware to 4.10? Did you use the WinBox drag&drop function? And did you make sure you only dropped the .npk package (download link for .npk file for your model http://download.mikrotik.com/routeros-mipsbe-4.10.npk).

I just did on my RB493AH board today, and works perfectly! I can only recormmend the 4.10 version, since it have a lot of features that 3.xx doesn’t have.

aaaaha.. finallyy its worked..!!! thanky everybody for helping Thankuuuu…very much
