Hi man! It's been years my iPhone 5 is dead like it is stucked on Apple logo( it turns on & off) I tried updating it to the latest software but then in recovery mode it got stuck & popped up with ERROR 21 mssg.
I tried many ways from UA-cam but didn't work.
I know it's too late for this... years has been past now but unfortunately my iPhone wasn't backed up so I've some personal data into it. Please acknowledge me if you can.

Error 21 is solvable just by dfu restore. Why did you had to remove nand?

[@mrony8632]

Boss why no more uploading videos almost one year no videos..miss you

[@mironcuha]

It has been 2 years now ;(
