    My yureka plus nit booted up. It switched on and hanged up in yu icon. When it hangs in the yu icon the Qualcomm processor is heating up. I tried to flash the mobile using new software, but it gets some error in the starting of the flash process. After doing such things now the Mobile not booting. When switched on it just the screen is black and showing failed to load image. What may be the problem. Is the memory chip has been damaged or the Qualcomm processor,or any some other issue. Kindly help me to service my mobile

    Hi Das sir, your all solutions are so impressive.
    I have also a query I am using REDMI NOTE 3 (32 GB), I was doing charging of my phone via MI 10000 MH power bank and suddenly didn’t know what happened, charging stopped.
    I have tried to charge with all possible things but it couldn’t help me
    So I went to MI service centre they checked voltage via multi meter but its didn’t show anything in it
    They changed USB connector but still the same issue so they said there is motherboard problem
    Is there any repairing solution if you wold like to guide us for the same

    • Santosh Das says:

      Maybe there is shorting somewhere in the the PCB. Get it checked Outside by some experienced Technician. They will Clean the PCB with IPA and Flux and apply Hot Air. This might solve the problem.

    Hello, I have got a moto g2 xt1068. It is water damaged and isn’t getting start nor responds to charger. Got it a chemical wash/dip from a local shop. He returned the phone saying board has short. Now what should be done??

    • Santosh Das says:

      Apply IPA and Flux all over the Board and then Give Heat using Hot Air Blower. If the problem is not solved then the SHORTING has to be checked and the component has to be replaced. Any good experienced technician will be able to do it.

      If the Battery Removable. If Yes, the BOOST the Battery Using Battery Booster and then Charge it. Also try to switch ON the Tab with a DC Power Supply. For all this, you might have to carry the Tab to some good technician.

    Hi Mr Das once more
    Im sori i figured out i was continuity meter settings…lol
    Sorry for the trouble. Last question would be…
    Do you power the board with a DC Power Supply or you just plug in Charger?

  10. George says:

    Hi Mr Das
    Im very interested in your article above since my focus is on getting dead phone working again. I have a little repair shop and its always been a challenge to revive dead phones. So far i understand how to fix shorting but my struggle is when a phone has no short.
    Right now i followed up with a device which has no short and the 0n / Off switch is giving me readings more than 800 to 1100 on multimeter pls advice.

    Thank you in advance.

      Changing the Whole Motherboard is the easiest way to Repair any electrical device. It is difficult for me to tell about THIS Fault without checking the Phone. So, Please get the Phone Checked by some other REPUTED Technician in your Area.

    Your phone needs flashing or Software Update. Get it done at any repairing center.
