Chosen Solution

my lumia 925 is not responding / or even blinking while charging .. its dead . .I have contacted nokia care they said its issue with the mother board and it cost around 80% of the mobile phone.. so got my mobile back ..

More than likely Nokia just wants to sell you a new phone. I would guess that a fairly cheap part such as the battery needs replaced, or possible the usb charging port but not the motherboard. These phone manufactures want you to buy new not fix what you have. Lithium ion batteries are great but they will not last too long without proper care. You should always use the correct charger for a battery, while most wall and usb chargers will charge your battery, some provide the battery with to much current and some with not enough which in time can cause the battery to fail, and not hold the proper charge. You may have a 3.7v or 3.8 li-ion battery, but if the battery voltage goes below a certain voltage(usually under 2.75) the battery will put itself into a protective mode, which most people would assume its dead. Also a battery which is rated at 3.7v usually won’t power on the device once it drops below 3.4v or less. Unless water damage is involved I would guess the motherboard wasn’t the problem.

I am also facing the same problem with lumia 925. It is 1 year and 4 months old. While it is connected to wall charger, the reset process (Volume down + power button) shown blinking of windows logo but the phone doesn’t start. When removed from charger, even this doesn’t happen. And when connected to computer/laptop, it shows driver not installed successfully. Now whether repair of such kind is possible or it’s just a dead brick.

same happened with me after two year use of nokia lumia 925 i bought in dec-2013, one kids playing subway surfer and mobile got heat after one hour i use fb than mobile hanged i restart mobile by using volume and lock key button but than only nokia symbol pop-up and than dead… nokia care said that they will send mobile at banglore for reparing and service charge will be cost about Rs.9000/- so denied and got back and given at pvt repair shop but they couldn’t repair it.

Hi Friends, i got this problem today from a customer. same time i was reading your messages regarding this issue. the solution is very simple, unscrew the phone take out the motherboard from the phone and set the temperature on 409C and give heat to the power ic for not more then 30 sec. and then let phone cool down. your phone will start work, then may you need to reinstall the software. thanks

This is ridiculous. How can Microsoft be ignorant of this issue when its affecting so many users. When a automatic software update could crash a boot loader, Microsoft should be liable to fix this with some sort of solution. This is a classic smartphone with amazing camera (not comparable to any other iPhone or android phones even today in the market). I have had this phone Nokia Lumia 925 since 2 years until I ran into the same problem day before yesterday. I spent 2 sleepless night to bring this up in every possible way but in vain. Phone detected as QHSUSB_DLOAD in PC. When its detected in “Care Suite emergency connectivity mode” there should be some possible way to flash the device and restore it. Downloaded the firmware to flash the loader.

  1. Nokia Care Suite - not able to flash
  2. windows device recovery - not able to flash
  3. Thor2.exe: - FAILED Sending OPEN_MULTI_REQ Message send failed with error code 8 Failed to get response to OPEN_MULTI_REQ ALPHA EMERGENCY FLASH END Emergency messaging closed successfully Operation took about 11.00 seconds.

so no luck yet…

Please remove your battery from your phone and charge it manually when battery full charge check battery with multimeter when it show 4-5 volts then put your battery in your phone .your phone 100% power on.
