If you don't rename to eboot.nb0 => Your device didn't flash it => Your device not dead. Have another files in the root folder of miniSD card ? List for me!!!
--Try this way :
Press both softkeys (two "-" keys) and remove battery then insert battery again (don't unpress two softkeys) and softreset, wait 2-3 seconds. It'll go bootloader mode. You can flash your device again.

What is your current bootloader, 1.01 or 1.05 ?
If you follow that menthod but it didn't go to bootloader, your bootloader was dead.
You can send it to HP to repair, or try this way : http://wiki.xda-developers.com/index.php?pagename=DeadBoot
I recommend to sent it to HP.

You was flash wrong bootloader due to make your device dead.
Now you need restore bootloader.
If you send to HP, they will replace board you must pay for it.
But you try the JTAG menthod to restore bootloader it'll make your warranty expired.

thx for all ur answer, i really appreeciated.
btw, for sure hp center will replace a board in it and that will be expensive rite?
if i sent to other shop which is not HP official service, will they do the same?
izzit juz flash using tools they hv>?
and expensive?

Here is what I did ... might help you
Hi
Make sure your phone is powered, it would be wise to charge the phone via AC power at least for 1-2 hours before you try to install anything.
I finally managed to install WM6 on my HP ipaq rw6828. But it wasnt easy, it took me 1 full day to get it installed. Just to help other people who are installing this, here is my experience -
What all I did and how I finally got there -
1.
Tried to install it via PC. When I already had a higher version of the Bootloader installed. Best way is to install it via 1GB mini SD card.
2.
After reading other posts I managed to downgrade the bootloader to version 1.0.1 (not sure of the version number...but its the version you get after installing the HP SP34074).
3.
Once I managed to downgrade. I got into the Bootloader mode on my device( its pretty simple to get into BL mode, make sure you ask someone to help you with it, its easier with two people, to get into Bootloader mode - a)press the two "-" buttons on the phone together. b)While the two "-" are pressed have a second person remove the battery. c) Wait for a few seconds and ask the person to insert the battery back. d)Once the battery is in place ask the second person to use the stylus and push into the soft reset hole (its hole on the left of the USB connecter on the phone). e) Wait for a few seconds and then phone should go into the BL mode. f) release the two "-" buttons after it enters the BL mode. Sometimes for me it entered the BL mode after I released the "-" buttons also. But dont release the "-" buttons till you have pressed into the hole with the stylus.
4.
With my phone now in the BL mode and showing the older version 1.0.1 (not sure but it should not be 1.0.5) I clicked the Device Software Update Utility.exe. I got the screen where you get a combo/dropdown with "ALL" pre-selected. The install step clearly says choose "OS" only and not "ALL". But I made a mistake here, for some reason using the mouse I didnt see any other option in the dropdown accept for "ALL". so I selected ALL and did a next. The setup kicked in and I got different screens showing status of install. But on the final screen it got stuck at 6% and stayed like that for well over 6 hours...I didnt touch the install as the instruction clearly say not to disconnect or stop the exe. But after 6 hours I realized that something is wrong and i killed the Device Software Update Utility.exe file.
5.
I did a soft reset on the phone and to my surprise after a while it loaded WM6....but that was it. Has the install failed in between the WM6 on the phone was totally screwed up...nothing worked properly. I coudnt even get ActiveSync to recogonise my device or connect to it.
6.
I tried the whole sequence mentioned in step 4 again but no luck now Device Software Update Utility.exe would error out I assume it could be because of the BL version 1.0.5. So I thought let downgrade and install the older BL version....but with no active sync i coudnt downgrade the device.
7.
Then i read somewhere SD card boot method to copy the EBOOT0908_MNT_1.00.05.nbf from the SP34074 and rename to eboot.nbo. This didnt work either, am not sure if I renamed the file correctly to .nbo(Orange) or .nb0(zero). Well I dont know whats correct eboot.nbo or eboot.nb0. But since this step didnt work. I was really upset as I felt I was stuck...then GOD had mercy on me and I did something which simply worked ...
8.
I took my mini SD card out connected to my Laptop in the SD card slot with the SD adapter. Did a quickformat to clean it up...if you have data its a good idea to back up the SD card in a seperate folder.
9.
Now I had a clean SD card with no files I downloaded the 1.0.5a (for 68x8) for miniSD. I copied the diskimg.nb0, size : 64,000 KB to the SD card root folder.
10.
Since I was trying the SD card method, I connected the mobile to AC power instead of the PC just to make sure I had enough power for install.
11.
I popped the SD card back into the phone. Removed the phone battery. Then entered into the Bootloader mode (refer to step 3 for getting into BL mode). Well nothing seemed to be happening...but I decided to stay on the BL mode .... to my surprise after 10-15 min i got a message asking my reset and goto factory mode. I wasnt sure if it was asking me to do something or was just a message. While I was wondering...the phone restarted automatically and it loaded WM6 ..asked me to do the tap thing to configure like the initial factory setup .. after all this I poped my SIM inside. Connected the phone to my PC. Active Sync finally recognized my device and synched everthing. Now everything WORKS!!! Though there are some issues like the camera flash doesnt come on.. etc but more or less everything seems to work. I havent tried other applications like email SMS wifi bluetooth etc.. I will post soon my experience weather all main applications work without a glitch...but am so happy my patience paid off..
Thanks to nhocbanme for WM6 version for HP ipqa rw6828, my biggest mistake was not to properly follow steps listed by nhocbanme. For people trying to install WM6 on HP ipaq rw6828....please please use the SD card method...it works and takes less then 30 minutes...you can follow my steps 8,9,10,11 to have a trouble free setup.
Good luck

Thanks you.

Hi WilliamSun,
if you can go to boot loader it mean you can repair your device. You should download WM5/WM6/WM6.1 ROM that design to flash via mini SD. you can download it from nhocbanme's or hellowordl1's thread, and flash your device again.
Good Luck.
