iPad Stuck in DFU Mode

I am trying to revive an iPad 5th gen wifi/cellular. Screen is black but when I connect to computer it is recognized as being in DFU mode by both 3utools and iTunes. Trying to restore on 3utools gives an error “ERROR: Unable to load RestoreRamDisk” and does not do anything. In iTunes when I restore it turns on with the apple logo and goes through the entire restore process, but when it is finished it goes right back to black screen and iTunes picks it up as being in recovery mode. Any suggestions?

You don’t really say much about what happened to the iPad before trying to revive it but this is a logic board related issue. Something is going on with the NAND, either it is not powered correctly or it is corrupted in some fashion. During the startup phase (or any Restore/Update action), the device goes through a self test of all subsystems and in your case, the NAND is not responding.

Tell us more about the history of the device and we may have a more precise diagnostic but this will likely not be a DIY repair

I got it the way it is so I don’t have a lot more info. It came in a lot that I bought of various devices and it was already in DFU mode when I got it. Thanks for the help I appreciate it.
