Nokia Lumia 525 is dead not even getting emergency usb mode how to fix it?

[maruf8]

Lately my lumia 525 has been bricked..And my pc cannot fild it when i am connecting through usb.. What should I do?

Sometimes it is just a dead battery. Verify in Device Manager that absolutely nothing appears/disappears when you connect/disconnect the cable to the device. Sometimes it appears in ports, sometimes HID or Keyboards.

If nothing at all appears, and your battery is good, then your only hope is R3209 trick. That should only be done by someone who is comfortable working with the circuit board.

What is R3209 trick? Can you explain me?

Are you talking about connecting usb by soldering some weirs inside the logic board?

The process is described here: https://forum.xda-developers.com/wi...indows-phone-internals-unlock-t3257483/page79

There is no soldering involved but do be careful. I already killed one device doing it this way, but I have also saved several this way.

Okay but can you tell me a fresh location of GND in the logic board?

And which side of the register i should connect with gnd?

 

[maruf8]

as i said, short the resistor. after that, it doesn't matter which side you connect to GND.

Thanks a lot mate, I'll give it a try tomorrow ??

Good luck. Just be careful prying the cover up above the resistor. those surface-mount components are very small and some are quite close to the edge of the cover. no need to fully remove the cover, you can just pry up the side/corner you need to access.

Thank you for your advice ?

sorry for my late reply... phone had connected successfully. and did everything he told. i did all things successfully, still it doesn't boot up.

That would not make it boot. It would allow the phone to be detectable by Windows device manager and allow you to restore the bootloader using Wpinternals.

yeah, but it didn't work for me. i pushed the bootloader. but still it is dead not finding by usb unless i connect the resistor with GND
