Boot loop after screen replacement

I have a friend's iPhone 5c and I changed the screen out for a replacement. I have done this several times on different phones with great results. This time the phone displayed a few lines of [NAND] dialogue, with the message "s_cxt_boot:88 sftl: error, unclean shutdown; adopted 863 spans". I found a blog saying to try replacing the frontcam/sensor flexcable, and the frontcam/sensor connector at the mainboard. I have replaced the first part, but cant find any instructions to do the latter. I have another phone that works, and could simply put the new screen on the other phone, but she has never done any sort of icloud backup and doesn't want to lose her stuff. Can anyone direct me?

Answer this question I have this problem too

Hi Jessica!

Yep, often error like these behave from an hardware error. This is the guide you need:

iPhone 5c Front-Facing Camera and Sensor Cable Replacement

A test you can do before buy any replacement is to disconnect, in this case, the front camera / sensor flex and without close the phone, try to boot again.

If the problem still continue, try also to disassemble the shield that hold in place the display assemble cables.

Cross my fingers for you..
