Hi, I have the Chinese smartphone Uhappy UP920, android kitkat.
I tried to root my phone with kingoroot and all other root software before one week, without success, kingo always said "connection with servers failed, try again", I tried it two days from different libraries & I tried some software for upgrade, just to see if it is possible to upgrade to the android 5 & 6, the upgrade was refused because developer didn't make such possibility.
I don't remember from all this software if I used any software for flashing device, but here is the problem:
in one moment after trying all these software, I saw that phone battery dropped from 10% to 1% and the USB cable didn't work any more, I tried OTG cable also but the phone didn't recognize my USB device, when battery was gone/spent, I tried to use USB cable to charge the phone with my computer, but no success. I don't have ac adapter (charger), I think it would not work in any case because OTG cable is not working, not only USB cable.
battery is gone, I can't charge it with USB cable, I tried to make restart with "down volume button" and "home button", but it didn't work.
when I press Power On button, display become something like blue for a second and it is dark again. I can't start the phone.
my theory is that some software destroyed possibility for android kitkat to recognize smartphone microUSB port (for USB cable, you can see that port on the photo: https://img.fasttechcdn.com/231/2314500/2314500-9.jpg). So, maybe it is software problem, maybe hardware problem...
anyone had similar problem? anyone has a solution?
p.s. before battery was gone, USB debugging option was checked, that's requirement when I tried to root the phone, in theory I could try ADB to do something with the phone, but I don't know how to use ADB, I tried to list devices but I got everything black in the terminal, I didn't get listed my device. if you recommend ADB, please tell me what commands to use.
