Iphone hardware and software solutions in 24 hrs

[Adrian1990]

Hello, I have one Iphone 6 with "No Network" problem. I have tried to restore it, didnt solve it. Sim Card is working in other phones without problems. Iphone has IMEI. Everything else seems to be normal.

So do you have any solution for this one? Or point me what should I look at?



Thanks in advance,
Adrian.

A friend have an iphone 5s that was with a bad battery ( turning off with 80%)
He was using it on charger and suddently the phone turned off and only showed apple logo and then reboots to apple logo again .
I tried two differents batteries and had same results. When i try to turn it on or when i try to plug a charger on it. Do you guys think its a u2 ic problem? since its the power manager ic, maybe the bad battery damaged it

hello,
anybody help?

iPhone 6s has been droped down on the floor.
Screen and home button are scrap. The phone starts with no backlight and image in service mode (iTunes). Both video rails /video & backlight/ seem to be ok. All caps look fine.
However low voltage on the PP_LCM rail gives food for thought. / ;-) :

PP_LCM_BL_CAT1_CONN: 0.0V
PP_LCM_BL_CAT2_CONN: 0.0V
PP_LCM_BL_ANODE_CONN: 3.96V

Those measurements led me that the damage should look much lower and I go much lower than, to PP_VCC_Main rail.
Here my measurements:
Power rails:
ground-ok
PP5V0_USB: 4.86V
PP_BAT_VCC: 3.94V
E75 rails:
TRISTAR_DP1_CONN_P and _N: 0.001V
_DP2_CONN_P and _N: 0.0V
_ACC1: 2.71V
_ACC2: 0.0V
TRISTAR_CONN_DETECT_L generates 0.04V

on the other hand PP1V8 & PP1V8_ALWAYS they have 1.8V

Question smarter than me: what should be the appropriate voltage on PP_VCC_MAIN and PP_BAT_VCC and PP5V0_USB in iPhone 6s?

thanks and regards,

Hi, everyone.
I have a iphone 5c where I changed the chip u2 because cell phone would not start, then the phone started working and worked a little less than a year precisely until now, in fact he is still working but I have a problem with time.
I tried to put manually and automatically, but after one day stopped again and walked random changes.
I tried it reset to factory settings but does not help, I also tried to change the battery but even this does not help.
I wonder whether there is a possibility that the problem again in this chip that I changed (u2), if he has anything to do with the time on the iPhone?
Thank you. : D
