    Hello, I can not start HTC Desire 12. "Normal" starts up with the message "COTA data processing", which takes a few hours and nothing happens. I tried to reset the phone, but I encountered more problems. The combination of Vol.down + power: I see "Fastboot mode" and nothing more. The Vol.up + power combination: a lying robot with a red exclamation mark and no command is displayed. What can I do with this. Please help.

    When the robot is displayed, press the buttons again. The recovery menu should appear and then select reboot system now

    After pressing the same combination, the phone reboots itself to the lying robot.

    I have the same problem with the same phone. The only thing I can do is to quickly enter the pin, which works in some way. I have not tried anything else, because I am able to start the phone, and if sometimes I do not manage to do it, I just restart the phone.

    Did anyone find any other solution to this problem? Unfortunately, inserting or lining the SIM card does not give anything, and restarting does not.
    HTC Sync can not see the phone, even under fastboot or Recovery mode.
    The phone switches on to the code input screen and the message COTA Data Processing appears immediately ...

    Even if you upload new firmware, how and where?

    I still have to try the hard reset option, but I would prefer to recover my data somehow.

    This is a fresh model - data is definitely crypted, so it will not be easy to recover if possible.

    Well, unfortunately, the model is not enough, that fresh is still not popular and not from the top shelf ... :P
    But you can see some firmware already found.

    Fortunately, I managed to make it usable without loading anything, even without restoring the factory settings.
    I just tried to run it in safe mode. When it was turned on, with the message "COTA Data ..." displayed, I kept the power button pressed, after the window appeared with the selection of switching off the phones, or restarting it, I held the "restart" option for a while until the message about starting in emergency mode, which of course I confirmed.
    I do not remember whether the phone immediately started up to the system, or if I had to quickly enter the PIN code to run, or repeat the procedure with emergency mode again ... but eventually the normal system turned on without this annoying error. I was able to connect to WiFi and update the software (relevant information showed up), the phone started again and for now it works as nature wanted. ;)
