Are you sure it shows HBOOT-0.92.0001 ???

The latest Hboot version is 6.93.. if that is your Hboot .. it difficult to get back but you can try this
http://forum.xda-developers.com/showpost.php?p=10919215&postcount=5
But if your Hboot is.. 0.93 than you can download below file.. rename it as only PB99IMG.ZIP and put it into root of you sd card.. and switch your phone by pressing volume down and power.. it will automatic detec the file and flash it..
IMPORTANT this will required a goldcard.. but your can try first without making one..
it might get your USB working

thanks for reply.
yes HBOOT ver is same as i mentioned.
ADB is not detecting my device as posted on your given link that i have to ADB but ADB is not detecting my device even though PC device manager shows Android phone.

When you are in fastboot.. that is volum down and power... update your driver with below
http://unrevoked.com/rootwiki/doku.php/public/windows_hboot_driver_install
and check adb

just installed drivers as per given instruction device manager shows Android ADB interface but again ADB shows error: device not found.

Download this

And than flash from this... I think you did not had USB debugging on .. when your phone was working... that could be the reason..
can you try this command ... fastboot devices

on flashing ROM got error [131]:CUSTOMER ID ERROR

yehs.. you need to create a goldcard...
Please check your ADB now.. is it is working ..creating a goldcard is easy
just go to
http://theunlockr.com/2010/03/10/how-to-create-a-goldcard/

ADB is still not detecting my device.when i have no other phone then how can i make gold card as gold card can only make through phone.

yehs you can... one of the easiest way is.. if you have any one around having android phone.. just put your memorycard in that phone.. and in market search for an app called goldcard helper..it will give you your reverse CID..
If you dont have that .. than also there is a way.. but it will take time and you need to do lots of thing..
what you can do is.. if you are using windows pc.. than you can install... virtual machine.. and install linux in it.. so when you open linux.. you can get your memory card cid from there.. i dont knw the exact steps.. but you can easly find on Google.. ...
Once you got CID.. you can follow the above goldcard guide.. from step 7..
On a other note.. remove memorycard from your mobile.. and than flash the RUU .. see what happer.. you may never know

i think you should try to make ADB work.. thought when I bricked my mobile .. i was not able to use ADB.. so I use my friend mobile to get CID... I dont knw if this tool will work witout ADB.. but try this too
http://android.modaco.com/content/software/308798/pc-application-goldcardtool/
Set veriables also
Right click My computer > Properties > Advanced > Environment Variables
under system variables click "path" and click "edit"
at the end of the line add a sem semi colon ";" and without a space put C:\android-sdk-windows\platform-tools - It should look like ;C:\android-sdk-windows\platform-tools then click ok.
Just let us know.. the results

no it's not working.already tried.check attached image.
now working on through linux.just downloaded vmware image of linux.lets hope for the good.i will post linux experience.

Ya i hope you will be able to get it from linux...
as when you will connect your memorycard in linux.. you can directly acces the sector zero where CID store.. so Inshallah.. it will work

Dont want to dissapoint you but read this
You can if you have Linux. You need a Laptop card reader slot and Linux. Once in Linux, navigate to a folder like /sys/block/mmcblk0/device/cid
I havent tested it out in a LiveCD. Check it out and tell me.
Programmers have tried writing applications to interface the sdcard in USB mode to get its CID number, but it needs a PCI slot or device-a phone-Either Android/Windows Mobile. A PC application may be specifically written for a PCI based card reader to read the CID, but such an application would be hardware specific for the particular brand of PCI card reader. You cant use it unless you are a programmer and know to do that. As far as I know there are currently no Windows programs that do that.
To clarify, Once again,
The only thing you need from your memory card to create a goldcard, is its unique CID number (which is inserted by the manufacturer of the card)
The CID is unique to a memory card. It is not specific to the device
You can get the CID of the sdcard from:
Any Android phone which can connect and use the adb command.
A Linux operating system running on a Notebook with PCI slot which can read a memory card. Note: YOU CANNOT GET CID FROM LINUX FROM A USB CARD READER of a PC/Laptop. You need the PCI card slot.
You can even get the CID from a Garmin proprietory OS or a Windows mobile based phone. There are utilities available online using these, which can be seen in a Google search.
Do not try to get CID from any PC via USB cable. It can display a CID code but not the correct one. It is said that "USB lies about the CID".

goldcard created can u please tell me that what should i do now with this goldcard?

issue has been resolved by creating gold card and stock ruu.thanks for the support (jhonybravo4u)

I`m stuck on the alpharev sense hboot version and the error i get while flashing the RUU is when flashing the system partition which in this case is smaller then the stock one, i suspect this is why after typing fastboot oem in cmd my phone only boots the htc logo (green letters and white background)
Please help
I solved my problem just by flashing the downgrade hboot from the alpharev site. I typed fastboot flash hboot bravo_downgrade.img in cmd after previously extracting the bravo_downgrade.img into my androidsdk\tool folder. I amnowcertain that my problem was due to having flashed the alpharev sense hboot which didn`t have enough space on the system partition. It turns out that my problem wasn`t really that bad.

[Q] Help with HBOOT

Hi, I have just bought a second hand Desire for my wife. The person I bought it off had changed the HBOOT and put Oxygen rom on it. She wanted it back to sense so I tried to flash the official RUU via HTC Synch thinking it would change the HBOOT at the same time. Now all I have is HTC in the middle of the screen with an exclamation mark in each corner.
Anyone give me a step by step guide of how to get it working again??.
Thanks in advance.....
Scotty.

cant u just flash the alphrev stock hboot or zip. or reflash recovery??

Read the adb and Fastboot faq via my signature (ignore all the adb stuff, read just fastboot).
Set up your computer for fastboot (or download Fastboot flash utility - http://forum.xda-developers.com/showthread.php?t=794638)
Download this: http://alpharev.nl/bravo_downgrade.img
Boot into fastboot (from off hold back and press power)
Using the knowledge from the FAQ and / or Fastboot flash utility, Flash the bravo_downgrade.img as a hboot (eg fastboot flash hboot bravo_downgrade.img)
Run RUU again
This may not make sense looking at it now, but read the FAQ and it will.

Any ideas??

Easy way- grab PB99IMG.zip containing bravo_downgrade.img from Alpharev, check md5 checksum (if it's not correct- redownload), put it on SD and boot to bootloader. Hboot will be flashed by bootloader itself

Download and unzip unrevoked, the easiest rooting method known to man. This works on any HTC phone, so if you have a different phone than the Incredible 2, just select whatever phone you have.

Dont worry what is already in there, thats nothing to do with what we're doing. Zune is an MS thing so its not implausable that its there.
1 thing though, is it my sdk tools, or googles? If its googles, check in the folder to make sure adb and fastboot are there, as they may actually be in platform-tools instead. Amend the line you are adding if that is the case. Or just add both, ie:
;C:\android-sdk-windows\tools;C:\android-sdk-windows\platform-tools

Remove RUU from sd-card or remove card- bootloader tries to flash it if file is found.
Also in bootloader mode you don't have access to adb- this requires running system or recovery.

This is bootloader screen but it finds update package (PB99IMG.zip) on sd card and tries to flash it- this is normal behaviour.

[Q] Problem on HBOOT screen

Hey guys, I have an HTC Wildfire S, and from what I can tell it is CDMA (does not have a SIM card), and apparently it goes by other names as well....marvelc, A510c, PG762. I managed to unlock it, root it, and s-off it, thanks to all the fantastic help here on XDA.
I am ultimately trying to get it so that I can try out different ROM's and such, so I wanted to install ClockworkMod Recovery on it as well. This is where the problem lays.
In the process of "playing" with the phone, I believe I screwed it up somehow....Apparently, in order to install ClockWorkMod Recovery, one of the steps is to press Vol-Down and Power at the same time, it WILL give the screen that says:
***UNLOCKED***

But underneath, where it says:
FASTBOOT
RECOVERY
FACTORY RESET
SIMLOCK
IMAGE CRC
When I plug-in tha usb cable to pc and it SHOULD say "HBOOT USB PLUG".... it does not.
I *should* be able to Vol-Down to RECOVERY and install ClockWorkMod Recovery that way, no? The problem is, I ***CANNOT*** Vol-Down, Vol-Up, Power, or anything...the phone takes over at this point, and the next thing I see is:

The phone flashes a few times and then "Get SW Version"...etc....
In order to use the phone again at all, I need to pull battery out and re-insert, and start normally.
I need to say, OTHER THAN THIS, the phone *does* seem to work normally....
What can I do to fix this? Is it a matter of resetting the hboot? Is this possible? Please help, I have no idea what to do....
Also, if someone can PLEASE give me a detailed step-by-step instruction on how to install ClockWorkMod Recovery, as well as CyanogenMod, I would be eternally grateful. Thank you in advance.
I have also made a video of me attempting to boot the phone and what I just described....but being as I am a noob here, they won't let me post it....msg me and I can PM you the link
PS. I should tell you guys I have tried this with fastboot on as well as off...same results.
Also, I found similar HBOOT problems in the threads, but they were not HTC-Wildfire-S, CDMA-marvelc-A510c-PG762 specific.

Time to feel silly you have left the pg76diag.nbh after you s-offed pal. The bootloader will Always look for this file and others and if it finds them and they are untampered with, and have the correct cid (s*on) then it will execute them. If you are s-off it will always execute no matter what the cid/tampered state. Delete this file and any other pj76 files from your sd card then boot to hboot. The device will look for these pj76 type files and if it finds none it will give you control of the volume buttons and activate the USB plug if it is attached

[Q] Restoring Android OS

Hi I just found my old phone and wanted to restore it. I honestly have no clue about this kind of procedures so I'll ask you to please be patient. I've been doing some research but wasn't really successful.
When I turn on the phone I get

No signs of the operating system is shown whatsoever. There is a list of options:
BOOTLOADER
REBOOT
REBOOT BOOTLOADER
POWER DOWN
I tried all of them but didn't get anything exiting. When I get to BOOTLOADER some screens are shown and then it says
Loading image [PG76IMG]
or something like that and asks "Do you want to start update". Just for the heck of it I pushed no and then it asked me to reboot. Then when I went to Bootloader again it showed the same thing but this time I pushed yes. It did some updating and then it asked me to reboot again but then the same thing happened.
How can I get past this screen? Does it even matter that I do? How can I install Android on the phone?
Thank you.

I think you don't have a recovery installed. Search for a recovery like CWM or TWRP in the forums and follow the instructons. By the way what did you do with the phone last time???

Hi thank you for your answer. I actually was looking for recoveries as suggested in another post but I'm unable to mount the phone on LInux or Windows when it is on fastboot. I have seen that many people can do this when they get into Recovery but I can't. Any hints on that?

I got this phone like a year ago and it wasn't working. Basically it was showing me the screen with the three Android logos and wouldn't start. I remember I tried some stuff I found on this blog to get a new OS on it but I didn't have much time back then as I was having finals. I remember I got the phone blocked and it said S-ON and was told how I needed to unlock it and turn it to S-OFF.

You don't have to mount it in fastboot you just have to take it to fastboot mode and connect to your PC and use the fastboot utility that comes with adb. However if fastboot does not work try to flash the recovery through SD card.....take your sd card connect to PC and delete the PG76IMG.zip that's there.....then download the flashable recovery zip and rename to PG76IMG.zip place it on SD and connect in your phone and again go to bootloader where it asks to apply update. Update it, turn off, delete or rename the PG76IMG.zip from SD and boot.......see if it can boot into recovery....or go to bootloader and select recovery.......for the recovery I will suggest TWRP (google for TWRP wildfire s) and download zip from there.

Stock HTC One M8 with Bootloop

Hi All,
Really struggling to find info for the bootloop issue on stock HTC one M8 loads for rooted etc
so my phone randomly restarted and then got stuck in a boot loop. i couldn't do anything i managed to get into Fastboot after waiting for the battery to die completely. got into Fastboot and factory reset. but no change.
The fix seems to be to flash RUU onto it but i cannot find any info on how to do it on a un-rooted HTC One M8.
Any suggestions/guidance?

also forgot to add if i choose Recovery from fastboot screen i just get a image of a HTC phone on the screen with a red triangle and ! inside.

RUU works fine on unrooted phones. Its an official HTC tool designed to be used on stock devices. You just connect the phone to a PC, boot into fastboot mode, and run the RUU executable on the PC, and the executable will do the rest.
This is provided you use the correct RUU for your specific device version (and not all versions have RUUs).
If you want more help on identifying the right RUU (if there is one) we'll need more info about your phone. In fastboot mode, open command prompt on computer, and do command fastboot getvar all, and post the results (delete IMEI and serial number).

That is the stock recovery. If you press vol up and power, it will show you the recovery menu. But there is not much you can do with it, that will help your current condition, aside from trying a factory reset.

Just saying you have the same problem, isn't going to do much for you; or allow anyone to help you much. Please provide specific information about your device version, as I requested from the OP.

RUU works fine on unrooted phones. Its an official HTC tool designed to be used on stock devices. You just connect the phone to a PC, boot into fastboot mode, and run the RUU executable on the PC, and the executable will do the rest.
This is provided you use the correct RUU for your specific device version (and not all versions have RUUs).
If you want more help on identifying the right RUU (if there is one) we'll need more info about your phone. In fastboot mode, open command prompt on computer, and do command fastboot getvar all, and post the results (delete IMEI and serial number).

That is the stock recovery. If you press vol up and power, it will show you the recovery menu. But there is not much you can do with it, that will help your current condition, aside from trying a factory reset.

Fair enough. To further elaborate on my experience.
I have the HTC One M8 Google Play Edition (Unlocked).
-Downloaded the RUU (version 6.12.1540.4) and HTC Sync Manager from HTC.
-Put device into FASTBOOT mode
-Connected device via USB with HTC Sync Manager open (Showed device was loaded with OS-5.07.1700.11)
-Ran the RUU. Phone displayed HTC logo
-RUU attempted to execute
-ERROR [155]: UNKNOWN ERROR -- The ROM Update Utility cannot update your Android phone. Please get the correct ROM Update Utility and try again.
-Felt confident I had the correct RUU. Proceeded with the Recover button. No success there.
-For confirmation, I know my phone is GSM so I also tried the RUU for AT&T and T-mobile. Again, same error result.
-Device maintains HTC logo on screen.
-After unplug of USB connection, device displays

I am not familiar with the the command prompt procedure (command fastboot getvar all), but I can provide what the phone displays under BARCODE:
