Friend,
I recently bought a brand new Arduino Nano.
When programming, I faced uploading issue even with the basic Blink example.
I came to know that chinese/clone Arduino Nano has this issue from years.
The only solution is to update its Bootloader using another 'original' Arduino UNO.
If...
Redmi Note 3 - 3GB/32GB Explorer edition phone.

Item will be double boxed for shipping for added safety.
IMP: This product comes with a factory unlocked bootloader. I will be shipping it out as is. Meaning, it has TWRP installed to prevent any future Mi update...
