    I tried again and got this:
    usage: fastboot [ <option> ] <command>

    commands:
    update <filename> reflash device from update.zip
    flashall flash boot + recovery + system
    flash <partition> [ <filename> ] write a file to a flash partition
    erase <partition> erase a flash partition
    getvar <variable> display a bootloader variable
    boot <kernel> [ <ramdisk> ] download and boot kernel
    flash:raw boot <kernel> [ <ramdisk> ] create bootimage and flash it
    devices list all connected devices
    continue continue with autoboot
    reboot reboot device normally
    reboot-bootloader reboot device into bootloader
    help show this help message

    options:
    -w erase userdata and cache
    -s <serial number> specify device serial number
    -p <product> specify product name
    -c <cmdline> override kernel commandline
    -i <vendor id> specify a custom USB vendor id
    -b <base_addr> specify a custom kernel base address
    -n <page size> specify the nand page size. default:
    2048


    So I have no idea what is going on

    Hello Everyone,

    I tried to unlock the bootloader and everything went fine until the last command prompt "fastboot oem lock". I got the below message;

    (bootloader) Lock successfully...
    (bootloader) TZ_HTC_SVC_DISABLE ret = 134086000 (0x7FDFD70)
    FAILED (status read failed (Too many links))
    finished. total time: 0.937s

    Ever since, I haven't been able to get service back on the phone. I also tried to re-activate the phone through Verizon's site and tried to do a factory reset. Still no luck.

    I also tried to re-do everything all over again and when I'm prompted to unlock the bootloader, after I select "Yes", the phone just shuts itself off.

    Can anyone help?

    Thanks in advance.

    Ok that last line of UNlocking the boot loader should have been fastboot oem unlock ....not fastboot oem lock. I think locking your phone right after unlocking it might have done something highly strange to it. Try repeating the entire unlock process from where you got the unlock token.

    Doh! Maybe that's why it failed. I managed to restart everything and all seems to be running. Except that I wasn't able to root it. Maybe I'll need to re-do everything and type in "fastboot oem unlock" when I find a good rom to load up. Thanks for the help.

    Anyone got the driver for "android 1.0" I dont know why but when I put my droid in hboot to get this going it says it fails to install the driver. I think this is because a had previously installed a different driver when rooting my incredible. What ever the reason I can not get past the "fastboot oem. . . " because I can not get my pc to load the proper driver. thank you for any suggestions

    Hey guys,

    I'm having some trouble here. I followed the directions, I'm on Windows 7, and when I run "fastboot oem get_identifer_token" I see the message '< waiting for device >' and it just hangs there. I've seen some folks in various threads around the 'net saying you have to make sure HTC Sync is not installed, but I've also seen a couple people saying that you DO have to have it installed. The directions at HTCDev seem to indicate that it should be installed. Regardless, when I click the link to the HTC Sync site, the Rezound is not listed as one of the supported devices for HTC Sync. What am I missing here?

    Thanks!

    Nevermind, figured it out -- had to install HTC Sync and, apparently, enable USB Debugging while booted into Android. Then the instructions worked.

    Hope you guys can help. I got to the step where I try to download the code from my e-mail. It doesn't ask where to install it, it just downloads it in my downloads section, it doesn't put it with the rest of the files that are on platform tools. Can anyone guide me in the right direction.
    Thanks

    Ok I got to the prompt screen and it says sending unlocktoken (0 kb)... but that is as far as it goes. I still am a little suspicious of the unlock file cause it downloaded in the download section, not in the platform tools folder

    are you in fastboot mode and do you have the recovery file in the same directory as fastboot and are you running "fastboot flash recovery [nameoffile.img]"?
