Hi,

Firstly, you will need to identify the IC by searching for Nokia Lumia Schematics on this forum.

Next, you would need to search Google for the replacement IC and do it yourself if you have micro-soldering skills?

If not, I would HIGHLY recommend searching Google again for "Nokia Lumia Ic repair specialist near me"

I hope this helps

First, with phone out of case, connect DC power supply, while watching current meter on supply, turn on phone by shorting to ground the pin 9 on the J2_AP 9 which you will need to keep shorted for about 3 seconds. Watch the current meter for sudden increase of current then make sure there are several distinct increases and changes. This tells you the logic board is likely functioning in the startup process. A steady current drain would indicate a short.
No increase in start current means board is not starting.

If all appears normal for starting, look carefully at the inductors (on the screen connector check DC continuity make sure they are under 2.0 ohms. If that's ok, make sure screen connector is properly seated and connector is not damaged.

Proceed to BL COIL, and Diode low resistance for BL COIL, standard diode test for BL diode. If no issues found change BL IC.

Try DFU mode then restore. If you get a 4005 error repeat this process a few times which can be required. The fact that the phone is recognized by you'd PC, likely indicates U2 OK. Note, that version of U2 is NOT interchangeable with 5c of 5s.

Hey team,

Mi iPhone 5s stood in DFU Mode and can't recover nor update it... when iTunes is trying to install the firmware it suddenly stops and returns 'ERROR -1' try again later.

I've tried everything already but still nothing has worked.

Any help will be greatly appreciated.
