thank for reading, help me please !

Sorry for your situation. You might have messed-up the firmware. I would try to put a fully charged battery and see if you can do a full reset by pushing the battery button for 30 sec. Otherwise you may have to send it to DJI for reprogramming

Get your friend to buy you a replacement aircraft, simple.

Looks like it needs to be reprogrammed - I'd ship it back to DJI to sort it out - it'll be cheaper than buying a new one and I'm sure your friend will contribute as he caused it!

Not recommend you to send the drone back, cause they will charge you a lot of money especially the shipping
Maybe ask your friend to buy you another one

Shipping, to DJI, in/from Vietnam, with no warranty?
My guess, that is in Hongkong, if DJI direct would be the receiver.
And needs customs clearance on both sides.

Question at DJI:
Is there a service available, in Vietnam, with the ability to  re-flash this Spark?
