So I tried to update the OS on my prime 4 via pc, but the installer froze in my pc, so I closed it and then tried it again then it failed to update after turning off and on the prime 4 is stuck on Engine DJ with the little chip icon that means it’s waiting for the software on the pc to update it, but the software refuses to do it keeps freezing or loads endless. After hard restarting it trying to downgrade the OS and to update again, I don’t know what to do anymore.
I tried everything I read all the other responses on this topic in this forum, and it just dost work it keeps in the engine DJ screen frozen, when I try to update via pc it keeps hanging on 3-9%, and it just stops after hours it keeps at 5-9% I tried to update via USB but with the screen only showing engine DJ with a chip I don’t know if It’s trying to read it or just dost even knows is there.

Have you tried updating via Wi-Fi (OTA)?
Or is it stuck in update mode? Have you tried keeping your finger pressed on the power button to hard restart it?

Please get in touch with your retailer or create a ticket at [Support | Engine DJ](http://www.enginedj.com/support).
I think there isn’t much we can do as a forum community at this point.
