So recently I wanted to make a backup of my phone and something unexpected showed up :o

That is weird, which twrp version so I can avoid it?

You didn't select data?

Is it the 101%? everyone seems to be much more surprised

@JoshBent I just wanted to write the description as specific as this I get from the analysis guy :)

This almost always happens with me. Added an issue with the maintainer of my device, no response 😅
Unless you're on Oneplus X too, Now I think this may be a recovery bug!

@doomsday I'm using OnePlus 2 :p

@nbamaral 3.1.1.1-0

@solooo7 I did but data backups only apps and apps' data not user data

@PaddiM8 it is a checksum of a file, and not me but TWRP. If I remember I have no other choice for one plus 2

@PaddiM8 I don't know why TWRP still uses it. In this case I don't care much about security. It's just a backup before updating the Android just in case

That's normal, it's because MD5...

...however, your backup will be fine and finish eventually.

@PaddiM8 Actually, the point of MD5 isn't security but integrity. checksum is calculated and saved at the time of creating the backup, and is verified at the time of restore. it ensures that the restore doesn't go through with a corrupted image. Wouldn't wanna damage the partitions with corrupted data
