How to flash using SD Card(Recommended):

Extract diskimg.nb0 to a sd card (<1G is better), insert it into 6828, press&hold 2 soft key(-) and reset. After a while, it will be in PBL mode, wait 15-20min, it will hard reset itself and flash done. The first boot time is very long so be patient , you may click the screen so that the device will not auto-off.

How to flash from PC with Windows XP (It is ok to run it in vmware)

Thanks Knave and rcperez for posting their detailed experience so I can write this section. Also thanks jimmyspa for improving the addheader's performance greatly.

1. Check your Boat loader version

(do a soft reset, and check the value printed at the bottom during the HP logo screen)

2. If you noticed that the last line states BL 1.00.05, it means you have boat loader 1.05 installed. You will need to download and flash your phone back to 1.01 via ftp://ftp.hp.com/pub/softpaq/sp34001-34500/sp34053.exe (VERY DANGEROUS, FLASHING VIA SD IS MUCH SAFER!)

3. After successfully downgraded your phone's boatloader, or your version was already v1.01, you can proceed to flash your phone to the rom.

With the check done, proceed with the required files.

1. Go to download section to download the rom file.

2. Download the file pcupdate.zip attached in this thread and unzip the contents to the same folder you used in step 1.

3. Download the latest Rom file and extract to the same folder

4. Run BuffereAddHeader.bat. It will take seconds to generate a diskimage_Ver.nb0. (You should have Java Runtime > 1.50 installed, http://www.java.com/en/download/manual.jsp)

5. Move your phone to boatloader mode ( press the two - keys, follow by a poke at the soft reset hole with your stylus )

6. Connect the phone to the PC

7. Execute the Device Utility Update program and wait till it verifies the state. Click on Update Item "All" use cursor keys to change it to "OS ONLY" then hit next **** SELECT "OS ONLY", if you cant change it to "OS ONLY" DONT PROCEED!!! It should detect your device as Model 0 etc.

8. Press Next to begin flashing.

9. Once completed, the phone will reset by itself. Wait for a while for it to startup.

Here are the notes & files provided by hochengsoon with README for flashing via Windows XP

PC flashing using BL1.0.1 must be done from C:\Windows\Temp, so why not start everthing from this folder ie PCUpdate + ROM + missing file(s).

2. run it and after entering the updating screen cancel it.

3. replace the hpRUU.exe in c:\IPAQ(default install) with the attached file hpRUU.exe in archive hpRUU.zip

4. Connect device to PC, then press and hold two "-" button and reset.

5. Run hpRUU.exe and do a normal update.

Note: you may delete eboot*.nbf to prevent bricking the device.

How to downgrade to WM5 using SD Card

1. Download this file: http://www.mediafire.com/?mbwxx9szmyz

2. Extract diskimg.nb0 to your sd card.

3. Enter bootloader mode by pressing two "-" keys.

4. Wait .

How to recover from semi-brick state:

1. Prepare a sd card with proper diskimg.nb0.

2. Pull out the batter for a few minutes.

3. Press and hold two "-" button and at the same time, put the battery in.

How to use kitchens (NEW writen by besfen):

Req: .NET2.0+

1. Download Kitchen Tools and extract it.

2. If you have diskimg.nb0 file that you want to modified, copy it to the TOOLS directory and ROM directory.

3. In "cmd", "cd" to the TOOLS directory.

4. Run prepare_imgfs.exe diskimg.nb0, it will dump the .nb0 file.

5. Run viewimgfs.exe imgfs_raw_data.bin, it will make dump folder in the TOOlS directory.

6. Run pkgtools.exe, select the dump folder and build package, it will make 2 folder, SYS and OEM.

7. Sometime some files don't move to that folder, you can open missing.txt file to know where the location of that file, move the files to the location said in the missing.txt. Finally, there isn 't files in the dump folder, all file are in the SYS and OEM. Delete missing.txt and OS.bat in OEM folder. SYS is M$ related, OEM is oem added things.

8. Replace the original SYS and OEM folder in the kitchen with new extracted ones.

User can change the OEM at will except the OEMDriver folder. I have modified it many times to get it stable on new ROM.

To add a new OEM Software, you need:

1. Extract the cab file of the app, you can use wincab manager to do this.

2. Put the extracted files to the new folder in the OEM. The folder name don't contain space, you can use _ (underscore).

3. Type the registry in the one of .rgu file. There are many .rgu file there, you can edit it with notepad. if you finish save as, choose all file and unicode type, but don't change the name of that .rgu file.

4. Make a shortcut, open initflash.dat file with notepad, the location is in the OEM_lang folder, type the shortcut name. You can read the existing shortcut in that file to know how to do it. Remember to make the shortcut file first in the folder of each app.

After that, just run build.bat file in the kitchen directory, follow the instruction and your ROM already created in the FLASH FOLDER.

GOOD LUCK.
