My phone switched off because it ran out of battery and when I tried to charge it it showed me a white screen with "active cmdline overflow (1613 bytes)" flashing at the bottom. I've Googled and read threads and they were all talking about flash kernels and all and I have absolutely no idea what any of that means. I've never downloaded or upgraded anything in my phone to alter the programming; I am a noob. The last Andriod system update was months ago. I have no idea what to do now. 'Recovery' brings me back to the same screen, as does 'Reboot'/'Fastboot'/'Reboot bootloader'. Now the screen is exactly the same except it no longer says "active cmdline overflow (1613 bytes)". I have yet to try factory reset as I just got back from an overseas exchange and I haven't downloaded all my photos to other devices. My laptop recognises that there is a HTC device connected to it, but it does not allow to do anything to the phone.
Any help would be much appreciated. Thank you.
