Hi everyone.
Every time I connect my ESP8266-01 to my computer using a USB to FTDI adapter, I receive the next error as soon as I reset it, and it answers to no AT commands:

What should I do? Thanks in advance!

can you upload a blank sketch to the MCU. Do not have anything connected to the device. After an upload reboot, does the checksum error go away? If not, most likely the MCU has got a booboo fatal boo boo..

Sorry? I could not understand.
I have not uploaded anything. I am not going to use it as a microcontroller. I am going to connect it to Arduino and use it to connect Arduino to wifi. Right now I am only connecting it to the computer, and as soon as I connect it sends that error.
