It is basically dad, it's possible from fastboot mode to activate de usb debug mode, and if it is, how can i?


I was just commenting on another similar question. Is your phone rooted? You can try this post's solutions to see if one of the methods work.

I believe you can flash a custom recovery via fastboot in case it's not present. Eg. -

fastboot flash recovery <<recovery-name.img>>
fastboot reboot-bootloader
Then use volume keys to select recovery, power button to enter.
  • Adding to this: at least TWRP on multiple devices supports being "booted" without being "flashed": fastboot boot <twrp.img>. So no modifications needed, plus it should even work with the bootloader locked. – Izzy Jun 27 '16 at 6:26
  • "it should even work with bootloader locked" - Isn't this a huge security flaw? Now anyone can access everything from the recovery without a hassle. Is there a discussion somewhere where I may read up? – blueren Jun 27 '16 at 6:55
  • I'm not sure if this is really the case (never tried it), so I might be wrong here. But the main advantage I wanted to point out is: no modifications of the installed recovery system are needed that way. And that is true :) – Izzy Jun 27 '16 at 7:16
