Hello everyone!
There is no power related problems, such as shortage of mA or not enough V or too many V ( I have the FTDI232 that has the 3v jumper), also I've measured everything with my multimeter.
I have 2 problems, I successfully flashed Espressif firmware on my ESP-12F(the little black one that looks like ESP-12E) and AT commands work, can change the baud rate, etc. but after I disconnect the VCC, remove the usb port, reconnect the VCC and connect back the port, i can't send any AT commands, every time I send something the led on the esp flashes like it received but no response whatsoever.
Second one is, whatever I try, I cannot flash nodeMCU on it or rather any other firmware except for electrodragon's firmware which works but throws garbage characters and sometimes throws the watchdog reset.
With nodeMCU, I flash the Espressif (shown as in the picture), then I flash nodeMCU bin at 0x0000 and it flashes but the ESP won't respond to anything. I tried to flash nodeMCU with the default esp_init_data_default.bin at 0x7c000 , it succeeds but after disconnecting GPIO0 and reconnecting the usb windows throws the "unrecognized/malfunctioned device" error.
(Yeah in nodemcu flasher I've changed the DIO flash to QIO)
