  Hello there. I am trying to flash the latest firmware v85 to flash an esp12 mcu. I am using esptool.py and following instructions provided on the website. Everytime the flashing finishes, the mcu restarts in a weird way with no led lighting and it consumes more power. when i try to connect there are weird letters and symbols and it says prompt not found. Any clue on how to fix this? i am using flash map for 4mb mcu. i have tried it using esptool, espflasher, nodemcu flash tool,etc. all same behaviour. any help is highly appreciated. thanks
