12monty34 · 02-08-2017, 21:01

Can someone exploain to me what R115 next to L16 on an Iphone 5s does?

It is missing on my board and i got error 4013

thank you

12monty34 · 02-08-2017, 21:12

and i cannot read it in my schematics but i think it is R116 next to R131

12monty34 · 02-09-2017, 11:44

i checked another pdf and it is R115. it is the PP1V1_GPU FB line... i think that may cause the issue because pmic does not get the feedback of it or?

12monty34 · 02-09-2017, 13:28

can someone please help on that topic? What is that Feeback line used for and does this maybe effect the restore?

After the water device? Adjust R115, without it will not turn on and not will sew

12monty34 · 02-10-2017, 19:58

I think it was only a screw damage device. So without r115 it will not boot?

12monty34 · 02-10-2017, 20:02

Compass ic is also removed :-) same blue redscreen issue... no restore. Device reboots when or before the restore bar is shown. Also error 4013. i think it is not the nand becasue no text error on screen, serial found and logs saying device unexpected state because it turns off ... so pmic and r115 for gpu feedback may have effects or?

On iPhone 5 there is no sores on the iPhone 5s after long screws. But R115 may be to blame.

can i jumper it or must it be a 10 ohm resistor?

PRO-mobile · 02-14-2017, 15:49
