Recovering data stored on NAND chip on iPhone X (Error 14)

I was wondering if it is possible in theory to dump data from a NAND chip to a larger capacity NAND chip, flash it with the stuff necessary to boot and put it back in the same phone?

The reason I ask is because my phone got stuck on the Apple Logo while I was preparing to back it up and now I am stuck on the recovery screen. I have tried to update it many times with no success (Error 14). My suspicion is that the phone is out of storage and therefore cannot complete the update. I have the log files for the update in case anyone has any ideas. Restoring is the last thing I want to do as the data is important.

Thanks, guys.

You can't read or dump the actual data from the NAND in an iPhone. You can get access to the metadata such as SN#, MAC address etc. This is what allows techs to install a different NAND IC and still have the phone work. Unfortunately, when you do this, you lose all of the data.

The only way you will get data off this phone is to find a solution to the error 14. This could be NAND or CPU related issue. However, the iPhone X is new and the logic board is sandwiched making troubleshooting difficult. If you want to have a real chance at recovering the data on this phone at this point in time, consider shops such as iPad Rehab in NY or G-Lon or Rewa in China. Or shop around your area but ask them if they have solved iPhone X in general and error 14 in particular.

Thanks for the reply, this is part of the log file I found where it says the device has run out of space. How can this be possible if the phone has a fixed partition just for the system files?

"ASR: Could not restore - No space left on device"

AFIK, that's usually caused by data corruption. This could be induced by an electrical issue (power rails not working properly) or failure within the NAND. If it's electrical in nature, the data may be recoverable. If it's a defect in the NAND, I don't think you will be able to recover the data.

I have the same exact problem but with an iPhone 6S! Was trying to back up but it ended up in recovery mode and Error 14.

No backup and in desperate need to recover all my photos. I’ve sent my phone to IPad Rehab in NY. Preliminary evaluation by them said it cannot be solved - probably due to NAND. I’m still waiting to hear back from them as they will take another look at it again before calling it ‘no fix’. So I know how this feels :(

I really hope that there’s a solution for this somewhere out there.

This happened to me on Sunday evening and I have noticed from my research so many people have this problem. My issue is that the update cannot complete because the device does not have enough space, only a custom firmware of a smaller size can fix it. Unless it's by Apple there is no way the IPSW file can be reduced in size at the moment.

@sfw2018 did Apple manage to fix for you?

Same here, iPhone 11 Pro with 64 GB of information lost. It's the same problem. Not enough capacity to host the &&^&^$^ 5GB of the OS. &&^&^$^ 5GB. I know I should've made a backup or something, but for real? If my phone is too full the only option is to wipe out everything? They should release a lighter version of the OS for this cases.

&&^& YOU APPLE!!!!!!!!
