As I explained before, if all you did was flash a brand new hboot/radio/recovery , then you wiped what was there, as such /system /cache /data were formatted and you no longer have an operating system installed, so naturally it has nothing to boot up into.

So you would have to boot into recovery and re-flash the rom, or restore from a nandroid backup.

If you can't get into recovery, can't get into the boot loader, etc then yes very good possibility you bricked it, though not sure which DesireZ hboot you grabbed as I flashed a DZ hboot on mine just fine. Just another example of double and triple checking information before you do anything with the phones.

That file name doesn't say what version it is, or where it came from. For example the only two hboot files I would flash would be either the G2 or DZ from this wiki : http://wiki.cyanogenmod.com/index.php?title=HTC_Vision (and currently I'm using the DZ one on this G2).

Though by the name of it, it sounds like you were trying to put the phone back into the original stock/locked state and flashed whatever the original desire-z hboot would be onto your G2. The problem is the Desire-z had more regions/firmwares/carriers than the G2 and flashing one without verifying first would most likely brick your phone, which is what I think you have done.

Personally once I've rooted/unlocked a phone I don't even try to bother putting it back into stock state for this very reason.

PS: I unzipped it to show the version : hboot_7230_Vision_HEP_0.85.0005_101011.nb0

I am not sure what region HEP is, and I haven't seen an 0.85.0005 before.

    Update 5 July 2011 : G2 users feeling like going back to G2 eng-Hboot from Dz eng-hboot (unity and doubleshot users) check out post number 2

    hello everyone ....

    im writing this thread as i could not find and adequate information on the wiki page about how to restore stock hboot on desire Z after installing ENG-hboot if you want to... after reading a million threads and asking alot of senior developers and mods over here i came to a working solution..... many of you might know it already but this guide is for people who are new to desire Z and this information is not present in Desire Z wiki......


    WARNING​

    THE FILE (HBOOT) I AM POSTING IS SPECIFIC FOR DESIRE Z WHICH WAS FACTORY UNLOCKED AND CAME WITH STOCK 1.34.405.5 ROM AND ONLY USE THIS HBOOT FILE AND THIS METHOD EXACTLY IF YOUR S-OFF WITH GFREE ASWELL WITH ENG-HBOOT INSTALLED..... IF ONLY ENG-HBOOT INSTALLED YOU SHOULD S-OFF VIA GFREE THAN USE THIS GUIDE....IF YOU DIDNT HAVE FACTORY UNLOCKED DESIRE WITH 1.34.405.5 ROM READ SECOND PART OF MY POST FIRST...... YOU HAVE BEEN WARNED AND IM NOT RESPONSIBLE IF TURN YOUR DEVICE INTO A BRICK....


    STEPS:

    (do a nandroid before starting incase you need to restore if phone gets stuck on htc screen after this procedure)

    1. Download this zip and extract stock hboot file (1.34.405.5 stock hboot for desire z) and copy to your fastboot/adb folder ....

    2. Verify its md5sum of the hboot*.nb0 (md5sum is of the hboot file not zip file) file with this

    md5sum = 613ddd077d65d51259795c02ccc2023d

    3. Then, from your computer go to command prompt and than go into your fastboot/adb folder

    adb push hboot_7230_Vision_HEP_0.85.0005_101011.nb0 /data/local

    4. After the file is pushed to the phone verify its md5sum on phone (being extra careful here) using this command:

    first write in command prompt

    adbshell

    and let adb deamon start...... you should see a $ or # depending on whether
    you have super user permissions or not....now write


    md5sum /data/local/hboot_7230_Vision_HEP_0.85.0005_101011.nb0

    and it should show up something like this

    md5sum /data/local/hboot_7230_Vision_HEP_0.85.0005_101011.nb0
    613ddd077d65d51259795c02ccc2023d /data/local/hboot_7230_Vision_HEP_0.85.0005_101011.nb0


    5. This next step is CRUCIAL. You must make sure that you are writing to the proper partition here or you could brick your phone. To be absolutely clear- the partition is mmcblk(zero)p(one)(eight) I'd recommend using an adb shell from your computer (with root privileges: just unlock your phone, run 'su' in adb shell, a window will pop up in your phone asking you to allow it to run, check for it to remember, then allow, the prompt in adb shell will change to '#') for the following command, as it will permit you to copy/paste it: ( if your already seeing # than you already have superuser permissions in adbshell)


    dd if=/data/local/hboot_7230_Vision_HEP_0.85.0005_101011.nb0 of=/dev/block/mmcblk0p18


    That should do it. You can verify that you have the Stock HBOOT by restarting the phone into the bootloader it should say

    something like "VISION PVT S-OFF" and the "ENG" would be gone......

    RETURNING TO STOCK HBOOT PART 2​

    If you dont have the factory unlocked desire z and your phone didnt come with 1.34.405.5 rom out of the box dont use the HBOOT file i posted.

    But you can use this method for returning to stock hboot.

    STEPS:

    1. For that you download the RUU file specific for your phone from the sticky stock roms section.....

    2. open the RUU*.exe file and while its open find the temp folder and locate the folder rom.zip.....

    cant find the rom.zip????? use this Guide... it helped me find my rom.zip on my windows 7 :)

    3. open it with any zip explorer (for some reason my windows 7 was not opening this rom.zip file saying it is invalid i used winrar instead)

    4. extract all files to some folder and go there to find the file named something like this.....

    hboot_7230_Vision_HEP_0.85.0005_101011.nb0 (your file might have different numbers in the end but its name will start with hboot)

    5. generate its MD5sum (there are many md5sum generators online use any you want)

    6. than use my guide posted above and use your extracted hboot*.nb0 file and using the name of your file rather than what i posted in commands above.....



    Credits go to our forum mod steviewevie for helping me out in restoring my stock hboot and getting rid of eng hboot....

    and also to vision wiki .... most of the commands and text i used here are from the eng hboot wiki section ......

    Guide to go from Dz-Hboot back to G2-Hboot (unity and doubleshot users)( For G2 only)

    Update 5 July 2011

    People who are concerned with flashing DZ-hboot on the G2 for Unity rom or Doubleshot rom..... You can use this guide to Return to your G2 Hboot be it Eng version or stock version .All the warnings and disclaimer posted in the first post apply here too.

    This is not For Desire Z owners. You will brick your phone if you apply G2 hboot onto Desire Z


    STEPS:

    (do a nandroid before starting incase you need to restore if phone gets stuck on htc screen after this procedure)


    1. For G2 Eng-Hboot download this vision.hboot-0.76.2000.zip


    2. Now simply extract the hboot-eng.img file from the zip and compare its Md5sum of the hboot-eng.img file with this md5sum 7669AE12DC2FAA10AE555A164980EFD0 and copy to your fastboot/adb folder ....

    3. Then, from your computer go to command prompt and than go into your fastboot/adb folder

    adb push hboot-eng.img /data/local

    4. After the file is pushed to the phone using this command:

    first write in command prompt

    adbshell

    and let adb deamon start...... you should see a $ or # depending on whether
    you have super user permissions or not....now write


    md5sum /data/local/hboot-eng.img

    and it should show up something like this

    md5sum /data/local/hboot-eng.img
    7669ae12dc2faa10ae555a164980efd0 /data/local/hboot-eng.img

    compare the Md5sums here from your phone .....


    5. This next step is CRUCIAL. You must make sure that you are writing to the proper partition here or you could brick your phone. To be absolutely clear- the partition is mmcblk(zero)p(one)(eight) I'd recommend using an adb shell from your computer (with root privileges: just unlock your phone, run 'su' in adb shell, a window will pop up in your phone asking you to allow it to run, check for it to remember, then allow, the prompt in adb shell will change to '#') for the following command, as it will permit you to copy/paste it: ( if your already seeing # than you already have superuser permissions in adbshell)


    dd if=/data/local/hboot-eng.img of=/dev/block/mmcblk0p18


    That should do it. You can verify that you have the Eng-HBOOT by restarting the phone into the bootloader it should say IN Second line "HBOOT-0.76.2000"

    and your done :)

    if your stuck on htc screen after restarting means all your partitions have been wiped. go into recovery ( ignore any errors like cannot mount cache) . do a full wipe,than wipe cache and finally wipe dalvik cache from advanced. than restore your nandorid backup. and preferably not of unity or doubleshot rom cause that will not fit in system partition....

    even though I've pushed PC10IMG.ZIP into sd card that I took from RUU, I stiil can't flash my device
    Click to expand...
    Click to collapse

    if you can .... download the pc10img.zip from virtuous Rom .copy it on root folder on your sd card (use someone elses phone to access the sd card or use card reader) and go into bootloader again. hopefully that will be flashed.

    from what i see maybe either you have the wrong RUU pc10img thats why its being rejected. or if you flashed stock hboot which is for G2 on a desire Z. that is checking the PC10img and than rejects it because it sees your phone as G2 and rejects the desire z stock RUU pc10img
