Code 52 when connecting to computer

So I have tried recently to flash my a6000 using a custom rom because lollipop update is horrible, laggy as hell. Somewhere in the process something went wrong, so my phone is soft bricked now. I have tried many several methods found on this forum, but none seems to work. I'm getting slowly desperate. The last one I'm trying currently is method using QFIL, but the problem is I get a code 52 error when I look up in the device manager.
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
What can I do? Also if you know a method that will work 100% to unbrick my phone I would really appreciate it.

Cannot get Watch to even connect to computer or use ADB

I just got my watch today and I've been trying to use ADB to install a rom but I cannot for the life of me, get this watch to connect to my computer (Windows 8.1).
I'm not sure why ADB is not detecting my device, because I use this same computer to root my LGG4.

I keep seeing this :
I've tried those guides that I found on Google (manually installing adb drivers, manually searching and installing the watch driver) but this watch will not work.
I've also tried disabling driver verification and set my machine into test mode and it still won't work.

Are there any steps I'm missing? I'm on Windows 8.1 and I really wanna root this phone to get more battery life out of it.
Thanks!

Need your help ASAP! HTC One X+ deleted OS and computer does not list device anymore.

Help! I have an Htc one x+ that i just recently flashed CM12 onto it. Bootloader is unlocked. I tried rooting phone and had some problems and decided to do a clean wipe. I wiped System and now the phone doesn't have an OS. I tried using fastboot and adb but the problem is that the computer doesn't list any device. If only the device was listed, I would be able to figure this on my own. What can i do now? Is my phone totally useless now? I have twrp 2.8 recovery installed. Is there a way to get the computer to list this device?

Computer doesnt recognize ZenFone Max

I tired EVERYTHING, and simply get get any of my computers to see the zenfone max.

When I plug the phone into any computer, nothing will show up on the computer side, and on the phone side it says charging.
-Yes I enable developer mode
-Yes I tried USB debugging on and off
-Yes I tried the usb options for Charging, MTP, PTP, MIDI
-Yes I enabled unknown sources
-Yes I tried 5 different cables
-Yes I factory reset the device twice and same thing

I tried all the options above, all in different sequence, and still nothing.
On both windows and linux machines it doesn't show up when I try "adb devices", and on linux when I try "lsusb".

Really stuck on a crossroads here if anyone can shed any light..

My computer won't read my microSD

So I bought one of those 64GB Samsung EVO microSD cards, and I wanted to move the files from my previous one (same type of microSD but with 32GB). When I plug the 32GB one into my computer, it asks me what I want my computer to do (e.g. open the files in a folder). However, when I plug in the 64GB microSD, I am not given this prompt, and if I try to open it from "My Computer" it says that it isn't formatted. I tried formatting using the prompt it gave me asking if I wanted to format it, but it said that it couldn't be formatted. So I tried using SDFormatter and it seemed to work fine, but when I tried opening it my computer still said that it wasn't formatted. I formatted it in my phone (LG V10 with T-Mobile, if that's important) after that, but my computer still says that it isn't formatted. Can anyone help?

New computer Maybe driver help??!?!

I got a new Razer Blade 14 laptop. For some reason I cannot get the phone to enter download mode properly. It just says disabled and "Connect USB Data Cable".

I've installed the drivers and ADB software. I Have no missing devices in device manager. When booted into the OS and in MTP mode I can send adb commands and "adb devices" sees the phone. Its only when I boot into download mode that the phone says its disabled and to connect a data cable. So theres something up with the Fastboot/Download mode drivers is my guess. I just cant put a finger on the problem.

In device manager it shows as "Android Bootloader Interface" as the device. I'm using the stock nexus 6p cable. My usb drivers are up to date per intel. Computer has windows 10.

Please help!!!

I can't connect my watch to my computer

Hi!

I have an lg g watch r, the device works with LeeDroid Urban Port ROM. I would have liked put on the device another rom but i can't connect the device to my computer. I have tried everything what i read in the xda forum that i would solve this problem.Nothing helped. The debugging mode is enabled in this device and adb mode is working, windows 10 op.system runs in my computer and newest google drivers are on it. Everything is ready that two device will connect. When i connect the device to the usb cable, nothing happened.
I think that the lg g watch r dock is wrong altough the dock charges the lg g watch r.
Please help me.
Thanks

Unable to recognize MTP mode on computer

So as a start to this, the phone is recognizable when running adb devices, I can see it listed there. However, when trying to use the phone in MTP mode, it tells me that there is not a suitable driver.

What I have tried so far:

1. Uninstalling device in Device Manager on Windows 10


2. Reboot both phone and laptop


3. Downloading the latest driver version from Google


4. Turning off USB Debugging on the 6P


5. Connecting phone


6. Attempt to use recently downloaded USB Driver on phone

So when all that is said and done, I get the following screens attached below.

I also tried using this guide to find a MTP Device:
http://www.howtogeek.com/195607/how-...er-if-it-isnt/

But that does not exist in either the latest zip download of the USB drivers, or the Google SDK drivers.
I only have the option for:
Android ADB Interface
Android Bootloader Interface
Android Composite ADB Interface

Could anyone provide me with some ideas?

EDIT: I have also tried two USB cables, both have the same issue. The Nexus 6P OEM Cable, and the iOrange Cable.
