3uTools-Forum

Hello I recentlly installed this app and was planning on installing 13beta on my IphoneXS. It downloaded fine but when I went to flash it to the phone, it gets stuck on 20% done, and gives me this error.
Error: Unable to restore device(-10).
Is there any way to fix this?

Hi, please check update of 3u and try again.

One easy fix is to use Joyoshare UltFix, because it won't result in any data loss.
Surely, you can back up the data to icloud, but you would still lose the data of some third-party apps after the restore.
Therefore, Joyoshare UltFix is certainly the safest soltuion.
