Unknown error 0xe8000015

I had all the same issues with unknown errors. Tried the power and volume button several times, still getting the error.

The only thing that worked was to hold the power and volume button until apple logo and reboot, but I held my finger on the down volume button until it rebooted with the itunes and usb cable on the screen. Then itunes picked up the phone straight away without error and restored the phone successfully.

Hope that helps someone.

Hi bekka. A similar problem was happening to me, where it would say the exact same error when I connected to iTunes. So what I did was held the home button and power button together for about 10 seconds or when you see the iTunes plug in signal (Just keep holding the 2 together until it appears). Plug it back in to iTunes and the update restore button should appear. First I just updated it but that done nothing so I just restored the whole phone. Also when it does update and restore the iTunes plug in signal on the phone is programmed to last 15 mins then it will go back to the "iPhone disabled blah blah" screen and it will most likely bring up the "cant connect this iPhone to iTunes'' don't worry about that just click ok and it should still update and restore. Hope this helps

I tried all of the above but with no success. I called Apple Support and got lucky; my senior technician was a Genius. He had me uninstall all of the iTunes components in a very specific and important order: 1) iTunes 2) Apple Software Update 3) Apple mobile device support 4) Bonjour 5) Apple Application Support 32 bit 6) Apple Application Support 64 bit. Then we redownloaded iTunes and once installed, we resumed the recovery conventional steps: plugged in the iPhone, pressed the home and power button until the iTunes logo appeared on the iPhone. Voila, iTunes then recognized the phone and we continued with the factory reset. Thank you Dionicio, you rock!

Connect you phone to PC via USB and have iTunes open. Hold down the power button, the home button and the volume down button. When the apple logo appears, keep holding down the home button and the volume down button but release the power button. It should show 'connect to iTunes' screen. iTunes will now recognise your phone and put it into recovery mode where it cam update.

Connecting the Lightning-to-USB cable to a different USB port on a Windows 10 computer (after starting iTunes as Administrator, and after restarting the iPhone 6s by simultaneously pressing Home and Power buttons) finally moved the process beyond the 0xE8000015 error for me.

I tried evey solution I could find. Try running iTunes as Administrator, this fixed it for me. FINALLY!

For error 0xE8000015, I held the home button, power button and the volume down simultaneously and iTunes recognised the device. 🙂

If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

I was facing this issue in my ipad .. Just go to %programdata% then go to apple computer delete the folder and then restart the laptop these steps are for Windows . Once you restart the laptop connect the cable to the ipad and turn of the ipad and press home button and power button together it will show you the screen connect to itunes. And then it will ask do u want to update and restore the ipad or restore ..And then it will work 🙂

Press power and home buttons and hold down till your phone shows the cable to connect itunes.

Your pc itunes will display the update/restore prompt

Follow instructions and your iphone will be working

I had the same problem with my iPhone. The pictures disappeared, it was repeatedly requesting login information for Apple Id and iCloud, all my apps malfunctioning and exiting abruptly. I didn't have a backup on iCloud or iTunes, and iTune wasn't connecting. I tried a bunch of things but I think this is what finally helped. I looked at my phone storage Setting>General>Available and saw that I had only 135 MB available. I deleted a bunch of apps and I was able to get it to 2 GB. Then I restarted my phone and I saw that my pictures started popping up again. I still couldn't backup or connect to iCloud. I'm guessing the software got screwed up when there wasn't enough disk space. So I reloaded the software (as in Hard reset, DFU, recovery mode) and with an update not a restore and I was able to get the software sort of working again. I am now able to connect to iCloud and am in the process of backing up.

I have exactly the same issue! And now I can't even connect to Wifi, I suspect the encryption functions is corrupted as well. There is no problem with Open Wifi (without password one).

Anyone can help?

what worked for me:

i have an ipad mini 4 that disabled its self after i updated, then asked me for my password to get in. after a few failed attempts, where it was only letting me try every hour or so, i came to this thread and tried what Zachiary said:

"

Hey guys had the same problem just put it in dfu mode and try again

Hold power and home for 30 secs till apple pops up then let go of the power button while you're still holding the home...
