Black screen and nothing else...

Lets make a long story short, i just got my OPO, as an advanced android user i desided to put
ParanoidAndroid 4.6, but before I installed custom bootloader (TWRP) and rooted it. Since i am installing new ROM i did a backup and then i needed to wipe my device, by accident i wiped everything from my phone, including backup and new ROM. I was left with TWRP (It is my 1st android phone without sdcard so i started to panick), then i started it in fastboot mode, to check if I can copy ROM again from my pc, but it didnt work. Then i went to restart options in TWRP and choose restart in recovery mode, then my phone turned off. Apperently it did restart but now my screen is just black and I cant do anything with it. I was holding power button, then with volume up, then with volume down, no result. When i connect it to my PC i hear sound that phone is connected but still nothing is happening. Please help me what should I do. My guess is when i pressed to restart in recovery mode, it wasn't meant to be the custom one, so it tried to open one that dosen't exist. My phone was charged 40% when i was doing that.
Note1: Unknown USB Device (Device Descriptor Request Failed), this is what i get when I check Device Manager.
Many suggestions were made so far none of them help. Hope someone will help me here!

First, TWRP isn't a custom bootloader, it's a custom recovery. The phone can't 'open a recovery that doesn't exist', it opens whatever recovery you have installed at the time. Make sure the phone is powered off (hold power for about 10-15 seconds), then try booting into recovery again (hold power + volume down).

Looks like you're using windows from the looks of you writing Device Manger so if you can boot back into fastboot then you're still okay!
Download this then just use the Flash CM11S option and it should bring you back to life.
Tool kits are amazing bro. Even as an advanced user myself they are still my favorite tools to use.

There is another problem

My friend you're in a bit more trouble than I think you realise you're in. Your device is showing up as QHSUSB_BULK in Windows, which means it's technically bricked. I believed you can save it though, have a look in this thread, you're gonna need to read through it all to find the solution you need. Let me know how you go.

[Completed] trying to put CWM on a p500

hello all, I'm really new to rooting and I'd like it if you could help me out here, this is about trying to get a CWM working on the smartphone p500. It's a new phone, I just put in the battery out of the package.
okay, so I've just rooted my p500 (root checker said it was indeed rooted), and I'm at a loss here. no matter what I try, I can't get CWM working. the first step I took was to try it via Rom manager. It got stuck at 100 % download, roughly the same problem as in this post
So I tried to get twrp, and got to this tutorial. I tried to put in the command "adb reboot bootloader". It appears as though this just shut down my phone, which would then display a "charging" symbole, since it's still charching via the USB. After putting in the next command; "fastboot flash recovery twrp.img", the command prompt returns "waiting for device", leading me to believe the phone has just shut down.
I tried to search the internet for another way to get in fastboot mode, but all I could find were threads about unbricking the p500 *after* booting in to fastboot mode. which should help, once I get there. This appears not to be an option, either.
After some more searching, I came across this post, detailing how to flash a custom recovery mod. Since I'm already rooted, I got as far as part III, step 5. step 6 is rebooting in recovery mode by pressing and holding volume down + home + power button. I've tried this while the phone is off and while it is on, but all it does is rebooting. Then, in this post, I read you need a custom recovery in order to boot in recovery mode.
Having come full circle, I've exhausted all my options. l've probable misunderstood several directions, or I have overlooked something fairly obvious. Can anyone help me?

[Completed] Potentially ruined my phone - help please!

So this morning I was trying to unroot my phone and return it to stock. I found a ROM and was going to use TWRP to flash it on and then replace the recovery with stock... except the ROM I found soft bricked my phone. OK not ideal but found a work around in the Sideload function.
I downloaded ViperROM and it was copying across but got stuck on 7% for ages. The screen was black but vibrating to the power button. After ages I assumed it has crashed so I yanked out the cable and tried to turn my phone off and on again... it doesn't turn off. It just vibrates away when I press the top button. So not only do I have a phone with no OS, I can't get it to turn off and on again.
When I reconnect it to my computer and enter adb devives I can see it's still in Sideboot mode. When I try to "adb reboot bootloader" I get "error: closed".
Any ideas on how I can at least get my phone to load the recovery again?
Please help!

Hi, thank you for using XDA assist.
You did not mention the device name. However,
There is a general forum for android here https://forum.xda-developers.com/android/help where you can get better help and support if you try to ask over there.
Good luck.

Homtom HT17 - SP Flash Tool not working?

Hi, I've been trying to flash new ROM for my Homtom HT17 (something is bugged in the system, the phone turns off 2-3 secs after the system boots up).
Using the Download option results in 'PMT changed for the ROM' error, so I tried doing Format All + Download and even though everything seemed to work fine (there was the progress bar and after finishing it showed success window) nothing changed (phone still turns off).
So I tried using just the format option to see if it removes the firmware and again even though there was the progress bar and it seemed to work fine, nothing changed (the system still boots up even though it shouldn't be there and then turns off immediately).
Do MTK6737 require different drivers than 65xx ? I've been trying to install various drivers and nothing helped so far.
What could be causing that?

Bricked unlocked device

Hello,
I recently unlocked, flashed TWRP and flashed Pixel Experience onto my Mi Mix 2s. After some time a notification of an available update appeared. I tried to install it but it didn't work. After some troubleshooting it appeared that I couldn't get my device booted into TWRP recovery mode.
I tried reflashing it via fastboot but that didn't work. It did not give any errors upon executing the command lines in the fastboot command prompt but just nothing happened. It just sat still like it was waiting, and waiting, and waiting.
So i thought, let's just reset the phone via the normal settings menu in Android. In hindsight that was quite a dumb move I guess, because after all the phone used to be working. But still I followed through and now it wound up in a bootloop. I can still get it into the bootloader mode, and in fastboot it shows my device when I execute <fasboot devices> but flashing or erasing the recovery doesn't work. It looks as if it sees the phone, can get info from it but is not able or allowed to flash anything to it. But it doesn't give any errors, it just seems to keep waiting on something, I don't know.
I hope any of you guys can help me because searching this forum or googling hasn't helped me getting any further. All topics I found at least had some errors in fastboot/bootloader mode which gave them a direction to go into...
So please help me!

Whoops, I solved it myself. On another laptop it magically worked the first time. Probably an issue with either the USB port or the drivers.
