Ok I found the solution 1.insert the battery 2.if you get the same problem as me Hold the button for 6 second to change mode(if not work ,try this step again to change mode) 3.remove the battery 4.on the device, connect gpio0 to gnd then insert battery the the led will flash for a second then gone(already in boot mode) 5.remove the wire that connect gnd and gpio0 in step4 ,do not remove the battery 6.connect tx rx and gnd with your usb to ttl then flash the firmware 7.after complete flashing ,remove everything 8.insert the battery and wait for 5 seconds 9.hold the button until the led flash continuously the release the button 10.wait untill the led gone 11.the device is ready
