PC wont recognize the phone (in bootloader) - HTC Rezound

So I was using the toolkit to relock bootloader, which I did successfully, but then when I went to flash the stock RUU, my comp will not longer recongize phone. I plug it in, and it says USB device not recognized. I have tried uninstalling and reinstalling HTC drivers, different USB ports and cords. Any ideas? I cant load anything but the bootloader screen as I dont have anything loaded onto it now that I relocked the bootloader.

How do I flash from bootloader?

I am trying to flash from the bootloader to recover from an installation error on my Fuze. I've entered into the tricolor bootloader screen by holding down Vol.down and reset. Now, when I plug the phone into the computer, the computer recognize the phone as a Qaulcomm CDMA Technologies MSM, and is trying to install a driver for it (which it cannot find.) When I run the Custom_RUU, it does not find my Fuze and is showing a ERROR[260]: Connection.
What am I doing wrong? Do I need to find a driver for Qualcomm first? I searched, and it seemed that when you enter bootloader to flash, it is suppose to say USB at the bottom. Mine says Serial. Does that matter?
If more information is needed to troubleshoot:
SPL is SPL-1.90.OliNex
Phone is unlocked by using Olinex's unlocker
Rom was EnergyRom 3.0 Phoenix 51909
Problem was caused because I tried to install Studio Kuma Traditional Chinese Fonts on it. That program works flawlessly on a WM6.1. Of course, Energy 3.0 are WM6.5, hence causing the problem.
Any assistance is very appreciated.
Try sd card flashing
You have connect your device to your USB port and let it find the drivers. In order for it to download the drivers, you must have Activesync or Windows Mobile Device Center.
Once you have one of those downloaded, launch it and connect the device while it is running normally. Opt to connect via Activesync on your phone. You don't have to have these running in the future but you need it to find the drivers and install them. Leave the Activesync connection intact while you run the Flash program.
Once the phone reboots in bootloader mode, the PC will probably download some more drivers. The Flasher will probably time out while the drivers are being downloaded and installed. Keep trying.
Once the bootloader drivers are downloaded and installed, try to run the Flasher program again. Sometimes you'll need a reboot if something is hung up.
You SHOULD be able to reboot, put the phone in bootloader mode (Down + Power + Reset) and it should change "SERIAL" into "USB". Once it displays "USB" you are good to go. Load up the Flasher program and it should go all the way through without the assistance of ActiveSync or Mobile Device Center.
I always flash in bootloader mode, I just know the initial pairing is rough.
Well, I flashed from sd card, and the phone is working now. Thanks for everyone's replies.

HELP! Computer not seeing phone in fastboot

I am trying to relock my phone and install the newest RUU to get the firmware updates and I have hit a wall.
When I plug in my phone everything is peachy when its booted up and running. When I reboot into fastboot and plug in the phone it is not being recognized by my computer. I have made sure that while booted debugging is on, charge only, and everything is just as it was when I rooted(besides a different ROM). The phone isn't showing up anywhere, not in device manager and not in the devices/printers area. It will however still power the phone as it will stay on even if I pull the battery. I am running Windows 7 64. Any help would be greatly appreciated.
Also I have tried uninstalling and installing the phone drivers in device manager and restarting everything over and over, nothing is working.

the problem might be from usb cable.
try another one if you have.
Got it, I believe it was a driver issue, but I went through several things so not sure what finally worked...

[Q] ADB doesn't detect device while in bootloader, can't unlock

I had my phone unlocked and working with a custom ROM in the past, but after some problems I gave up and just relocked it and went back to stock. Now I'm trying to unlock it again and I'm running into some problems. I'm unable to get the identifier token to use with htcdev because whenever I go into the bootloader my phone is not recognized by adb. fastboot oem get_identifier_token leaves me with a waiting for device message, and adb devices returns an empty list. If I turn the phone on normally the device shows up then. To the best of my knowledge, I have all the necessary drivers. I have tried multiple USB slots, multiple computers (including the one I originally did the unlock on, when it worked fine), and have searched all around the internet and various forums for an answer. I've tried manually updating the USB drivers through device manager, but that did nothing. I have HTC sync installed as well. When I plug the USB cable in I sometimes get a device cannot be identified/has malfunctioned message. Device manager also shows a yellow warning triangle on my phone when in the bootloader. I'm on windows 8 currently, but I've tried it on a windows 7 pc as well with the same results.
tldr: adb doesn't recognize my phone while in bootloader, so I can't unlock it.
Thanks in advance for any help, I've tried everything I can think of.

You're gonna have to be a bit more specific with how you're trying to read the device:
a) When you're in bootloader, and you have the phone plugged in, does it read HBOOT USB, or FASTBOOT USB?
i) If yes: Then just run the program. It will still recognize the system even if Windows doesn't show it. Fire off a CMD command or simply click "reboot" on the toolkit and see if the phone responds.
ii) If no: Use another cable, and make sure you're securely connected. Generic micro USB cables tend to be a bit loose even when connected, so make sure the cable itself is not "ajar" in the port
Once you're in bootloader mode, post what it says here.

Hi and thanks for the reply. Im using the OEM htc cable and everything else reads just fine. I'm able to read the sd card and send some commands through the toolkit. For example i can click the "boot into bootloader" command and it works fine. The problem is once it is in bootloader the command prompt window just says waiting for device and the phone says fastboot. I am able to reboot the phone back into android using the vol keys and the power button. Im trying to relock the bootloader using toolkit but on the second window (first being putting it bootloader) it won't read the phone following the computers message saying usb device not recognized. Thanks again for the help.

You may have to try it manually. Download a fresh copy of the Android SDK tools
and put the "Platform-Tools" folder under your C:\
Fire up Command Prompt, change directory to that platform-tools folder.
Then type in "fastboot oem lock" (without the quotations).
Your phone will reboot and upon the bootloader, it should say **RELOCKED** at the top.
If you're still having issues, I would suggest loading up on another computer, or if that isn't possible, download Ubuntu and burn it as a LiveCD and see if your phone will be recognized (properly) through Linux. Sounds like the communication protocols for your phone are fuxed. As for uninstalling and reinstalling drivers like that, you may have to use regedit to completely remove trace portions of those previous installs.
It's a driver issue, uninstall and reinstall the drivers.

USB Debugging Only Charges Phone

I can only connect to my computer through normal usb, fastboot, and s/w and upgrade mode, but not usb debugging. And yes I have reinstalled my drivers over 3 times, and factory reset plus reinstalled u-boot and xloader. I tried different ports and usb cords and still nothing. The phone only charges or will say connected as installer, and the pc will see it, but i can't use it as an adb device or a storage device. I have had this problem for 3 months after trying to unlock bootloader and just need to spitball some ideas.
I do think this is a pc issue because it doesn't work on other pcs either.
