I have problems with my HTC Desire 820 (single SIM) phone, have been unable to fix it myself or seen any reference to the problem(s) on all the websites & forums I have visited.
The phone, by the way, runs very smoothly, is quick & its overall performance does not appear to be hindered by the issues mentioned below.
My intention was to root the phone, firstly I unlocked the bootloader as per the HTC Developers website. The next step was to root the phone however this is where the problems started as the phone refused to install the recovery & by implication, the SuperUser. Regardless of the utility used & I have since tried many (I really like the Windroid Universal Android Toolkit), the root does not occur. Have tried via laptop using 8.1 & later Win 10 & desktop PC using Win 7 & later Win 10 – same result, no root.
I have tried to relock the bootloader, however that will not work either.
There are two more problems, firstly the Factory Reset (buttons & software) now do not work either. The phone “gives the impression” it is doing a factory reset, however it has absolutely no effect. The final problem is that the phone now refuses to install the latest update (1.05.980.6), I select update, the phone restarts but immediately goes to the HTC Fastboot screen & waits for my next command. Regardless of the commands selected, when the phone has fully booted up, it tells me there is an update to install & asks would I like to install it – clearly a circular argument.

So in effect, my phone will remain on Android 4.4.4. indefinitely unless I can resolve the issues.
The bottom line is that I really do want to resolve all the issues - help please.
