    Hi Friends,


    I faced the the same issue and it is solved now....

    See the link below and follow the trick (if required repeat the trick for 2 or 3 times)


    Thanks to @jayb222

    In My Case, I did the following steps...

    After getting a full black screen (even no "low battery warning" screen after 1 day) and not even boot into recovery / fastboot...

    1) Kept the phone for 12 hours without touching and charging...

    2) Plug official charger and usb for a moment... and tried booting... Nothing happend

    3) Charged with official charger and usb for 6 hours and then

    4) Pull off the usb and put back again ... and i got the LOW battery screen again,
    WOW, staying for 4 / 5 mins...

    5) Now don't try to boot or anything.. keep it charging for 30 mins more and let it be charged
    upto atleast 10% (you will see normal charging battery icon screen) even
    it is black.

    6) Now finally boot your device by pressing power button for few seconds

    7) Phone should boot normally...

    Note: NEVER Let your Lipo / Li-ion battery discharge below 3% to avoid this kind of problem... otherwise Battery protection circuit will be activated and hence preventing your device to accept charge...

    Best charging practice for lipo battery is Partial Charge, like -- 30% to 80% or 10% to 90%

    Let us know the result....


    Another Solution , if the above process not worked ...

    2) Submit Ticket to OnePlus Support or ask for RMA.

    3) Disconnecting and re-connecting the battery Like --

    4) =================== THEORY ====================================
    for Lipo Li-ion batteries.... if it discharges lower than a battery voltage (say less tha 3volt / 2.7 volt)

    If the lipo battery voltage drops below 1.5Volt, it might damage forever. Boosting it will not help to bring it's life back.

    then a security protection battery circuit takes into action and prevents the battry to get charge ... and goes into a deep sleep mode

    if someone can charge that battery with some special charger (NiMH) with 1C, 1amp charger for 15 sec to 1 min , it will then deactivate the protection and after that , we can normally charge that battery

    here is the link for it --- http://www.rcgroups.com/forums/showthread.php?t=1072324

    Thank you for letting us. Today my OPO discharged completely, just had to plug it in and charged perfectly but I'll try to avoid those kind of situations.

    thanks for your update,
    however, i think my problem is a bit different from yours, please hear me out and please help me out.
    here is my problem:
    • the screen is black but the backlight comes on but no type of screen images come up.
    • i can still lock and unlock my phone, i can hear the sound also.
    • ive tried restarting my phone, with the volume down and power, but nothing comes up.
    • occasionally, the screen is displaying something, but the display is disrupted, just like a jigsaw puzzle.. after that, it is not responding.
    • Is it a LCD problem?
    thankyou, my friend..
    at the same time, i will be trying your method too.

    I guess , it is not battery problem... Can you see boot logo, when you pressed power button ?

    Try to boot into fastboot (vol up + power .. when vibrates , release all) , then freshly install cm11s

    Follow this link ...

    -fastboot flash boot boot.img
    -fastboot flash system system.img
    -fastboot flash recovery recovery.img
    -fastboot flash cache cache.img
    -fastboot flash modem NON-HLOS.bin
    -fastboot flash sbl1 sbl1.mbn
    -fastboot flash dbi sdi.mbn
    -fastboot flash aboot emmc_appsboot.mbn
    -fastboot flash rpm rpm.mbn
    -fastboot flash tz tz.mbn
    -fastboot flash LOGO logo.bin

    -fastboot flash userdata userdata_64G.img

    -fastboot reboot


    it problem persists ... most probably LCD H/W prob... go for RMA / Support ticket...

    I'd Just like to tell the OP that I love him in the strictest non-homo way :')) Cause now my baby is alive and running again.... Hope was still alive and I'm so happy!! They should make this a sticky just in case other people have the same problems they can find the solution easily.
