control HTC phone with broken black screen

Hi.
I have HTC Desire V with total black screen, but touch working well.
It totally stock phone with no USB debugging and else.
I want to use it as wifi webcamera. can somebody help to do that?
i tried to unlock bootloader and think it done - there at most right spot where some lines visible and i saw, like in manual (how to unlock bootloader) confirmation about unlocking bootloader after adb work, so bootloader is unlocked. what else i can do? i tried to enable usb debugging through adb, but it says "error: remote not allowed". think there s-on active, but cant make it offline - it not allowing me to flash new recovery. thanks for any help. i read a lot here on xda about similar problems, but nothing found that help me. thanks again!
No help indeed...
Looks like all much more complicated.....

fastboot oem unlock not allowed! even after unlocking it in developer mode

Hello everyone
Recently I've hard reseted my lenovo Phab (pb1-750n) mistakenly before removing my google account and unfortunately I stocked in google FRP lock, I've searched many sites and seen many videos to bypass the FRP with no success.
Finally I found a russian forum that uploaded the Chinese version of device ROM, since the google apps are banned in China therefore updating the ROM from recovery mode succeed (I downloaded ROM and put it in the SD card, then update the ROM from recovery) and device got back alive again. (NO Google NO FRP )
but the second struggle wave slapped my face, (NO google apps NO joy ), for instance I downloaded Gapps and tried to install it by replacing stock recovery with TWRP, so in device, I turned on developer mode by tapping build number many times and turned on USB debugging and oem unlock, see, I turned on damn oem unlock!!! but in the fastboot when I run the
Code:
fastboot oem unlock-go
, the result ends in oem unlock not allowed report and
Code:
fastboot flash recovery TWRP.img
also failed due to the bootloader lock status. BTW international ROM seems to be all in Chines clouds and is not accessible for non Chines people to download them, at least I couldn't do it.
any idea what is wrong in here????? did Chines made ROM to be like that???? any chance to solve the issue???
this happens because you do not unlock the bootloader, just released to unlock

Click to expand...
Click to collapse
well, after updating system to the 6.0.1, problem solved, it seems android 5.1.1 stock ROM for this phablet do not allow to unlock bootloader, I found it in a russian forum, they said so.
anyway thanks for reply.

Question OEM unlock not available?!?!

I have a oneplus from metro by T-Mobile and in developer options the OEM unlock option is there but I can't click on it is a really light color gray does this mean I can't unlock the bootloader? Please help I'm a noob
Apparently, your device is locked by carrier. I doubt that you will be able to unlock it. Anyways, according to your words I wouldn't advise to touch developer settings at all.
