    Hi, my phone is H990DS and is stuck in Firmware Update screen with error 910K B50.
    I tried to flash winth LG UP the H990ds10c_00_OPEN_SG_DS_OP_1214.kdz firmware creating proper LG.dll file but my phone doesn't restart and it is stuck on Firmware Update screen.
    How can I fix my phone?
    Do you know what is my problem?

    You soft bricked it. It's still fixable. Try to go to Android recovery mode and clear the cache and do a factory reset. If that does not work, you will have to reflash the OS... you'll have to download the correct firmware for your model, go to Android boot mode, and then use ADB sideload to reinstall the firmware OS. Check or ask XDA for help, they specialize in that over there.

    wait wait. pull the battery and then put it back close it up, put the power cord in and then boot It Up. I have the exact same problem and it's got to be plugged in because I think it's a precaution so that on a firmware update it's big trouble if the power goes out so they force you to have constant power.

    You may have to call your carrier and ask them to push the firmware upgrade again cuz if it went away and it comes back it may come back when your phone's not plugged in.

    I'm not sure if the phone also has got the factory reset command.
    I've not tried the ADB mode yet and I hope to fix my issue..

    You mean that does the phone need to get a quite charge to boot regurarly and I have to let the phone gets the charge for an enough time?
    I don't remember fine but as I know I did it..
    My carrier is a problem because I need to ship the phone far for repairing...
