The device does not turn on, by connecting to the current it starts charging as in the picture, with the red LED flashing, then it turns off. If I try to turn it on (always under charge), it gets to the HTC logo then it turns off, if I press power + vol- the bootloader starts, but selecting any option remains blocked.
I connected it to the computer with windows 10 and it detects QHSUSB_DLOAD. I searched the forum and found this:

so i tried to use ubuntu 12.04.05, but it gave as result: 9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

My question is: can the battery be completely discharged, (I have been using it for 6 years) and then replace it, or is it another problem?
Looking at the bootloader O.S disappeared, why?

Thanks for your attention and sorry for the English.
