iPhone X stuck in recovery mode after maxing out storage. Getting "Error Code 14" So a couple of weeks ago I restarted my iPhone after it started glitching like crazy, when I tried to boot it up again it got stuck on the Apple logo. A couple of days later I found an article that said something about booting it into recovery mode and then updating it through iTunes would fix it, well big mistake. Now it's stuck in recovery mode. I have tried every possible thing I can think of to boot it out.
Including:
Updating it in iTunes
Updating it in Finder
Switching cables
Switching computers, from Mac to Windows
Using Reiboot to boot it out of recovery mode
Using Reiboot Pro (Paid Version of Reiboot) to &quot;Repair the operating system&quot;
Using 3u tools to repair it.
Using checkra1n to jailbreak it in DFU mode
Using a Windows computer to try to mount the iPhone as a removable storage device
And a couple of other 3rd party tools. None of which have successfully fixed it.
Any help or advice would be much appreciated.
P.S. This iPhone is a business phone with a lot of important information on it that hasn't been backed up in quite a long time, so it's very important for me to try to get the information off of it.
Thanks
If the iPhone is currently stuck in a reboot loop, try to enter DFU mode and restore it using iTunes.
DFU mode is entered by:

Connecting to Mac with Lightning cable
Press Volume Up, then Volume Down quickly
Press and hold right (Standby) button until display goes dark (about 10 seconds)
Keep holding Standby and also press Volume Down for 5 seconds
Keep holding Volume Down, but release Standby button

While the display stays black, iTunes or Finder should say that it found an iPhone in recovery mode and you will be given the choice to return it to factory settings which will wipe the storage and apply the latest firmware.
Entering DFU mode from a reboot loop is very tricky, since it is likely to reboot before you are finished. Try to start the procedure as soon as the Apple logo is displayed and don't be discouraged if you need a few tries.
If that doesn't fix it I would contact Apple, maybe the storage is faulty. Flash storage needs free space for wear leveling and running it near full for a long time can cause a lot faster aging of the memory cells. I would recommend keeping at least 20% free space to counter that.
