A03 fastboot mode
 

Guys I have a Samsung A035M (A03). is on the following fastboot screen and does not exit. I've already checked the keys and none are pressed directly, there's no trace of oxidation. update would be the next step, how could you update it, it doesn't go into recovery, it doesn't go into download.

what program could i use to make the flash? at test point it is recognized on the pc.

thank you from now.

remove battery and hold v- and put cable it will go to download mode

I already tried to do it that way but it doesn't go into download mode.
