I'm trying flash the AT firmware and use Arduino UNO to flash it.The process I follow is I hold GPIO0 low, since the power is ON until the flash finish, disconect GPIO0 and power, i return power it and the ESP dont start, the blue led always is ON, and dont blink. Power... I use a PC power supply... Should reset from pin?

To flash the device, GPIO 0 should be low, GPIO 2 should be high when the device is booted. At this point, the device is read to program. Now you can flash it.
Perhaps if you attached a photograph of your setup, that would help.
How are you powering the device?

Perhaps it is a different using with the arduino. I am using nodeMCU and the programming adapter I told about viewtopic.php?f=13&t=4132
I do it the way I wrote and it works fine.
