iPhone 11 Pro MAX Error 4013 4014


Got an iPhone 11 pro max with iTunes error 4013.
18%-21% error on 3uTool.
Finder on MacOS error 4013.

Phone stop working after update (customer words) so idk what is the true.
4 me phone looks very good.
There's no liquid damage and also don't look like he was after drop. Screen and back screen almost without scraced.

I2C lines are OK, even oscilloscope preset some image and doesn't have shorted line.

I've got some more 36mA on start in IC NFC_S (200VC111) just for half second - have no idea if is correct - on other board start is always 0mA so i replace this IC and still get an error 4013 (also don't know is this chip is programming and split with the board :sad)

NAND V+ (0.9V/1.2V/1.8V/2.63V) are present .
After replacing nand with same svcfg information get error 4014 - same like without NAND ps. no more upgrade memory in newest version iPhone?

So I decide to reball CPU and after that is same situation. All procedure reballing CPU was perfect - I'm good.

4 now don't have more ideas so thats why I want ask u.
Some advice?
Thanks h.

iPhone error 4014 or 4013 often happens when you try to update or restore your phone while connecting to iTunes.

When this error message pops up, you'll not be able to do anything with iTunes. So the best workaround is to bypass iTunes and use a thiry-party tool like TunesKit iOS System Recovery to solve the issue.

After reading your message carefully I suppose two problems related to this based on my experience on 4014 after 4013
