[TUT] HP iPAQ 61x, 91x Stuck @ Bootloader solition

---

Hi all.
I have 3 semi-brick iPaq device (612c, 614 and 912c). After do a ROM updrage from a bad miniSD card, these device onli show me HP logo when turn on. I'v search too many time and find a way to bring them back. @XDA-dev, I've saw someone have brick iPaq like me.

You need:
DNW (Include Driver file) http://www.mediafire.com/?zmnmzmwnjtk
Your device's Flash.DIO file. How to make a Flash.dio I'll post later. But you can found .DIO file via searching the web.

How to:

- Open DNW.exe, [Configuration] => [Option], change [Download Address] from 0xc000000 to 0x3000000
- Rename FLASH.DIO to FLASH.nb0
- Bring your Device too download mode: RECORD + OK + POWER or RECORD + OK + Reset to enter Download mode. Note: It's not Quanlcomm download.
- Plug your device to PC, and manually select driver to install (files are in SEC folder)
- Back to DNW.exe and [USB Port] => [UBOOT] => [UBOOT] and select Flash.nb0 just renamed and waitting for programed

I've done with these ipaq last week and return them to my customers. These Combine-key to enter download-mode can be wrong with 9xx device. I'll find another device to test later
This solution can change language of your device to language of .DIO file

How to make a .DIO file:

- You can download ROM update of your device from HP official web site.
- After download, extract (don't run) file to a folder by winrar, 7z or another archive manager. You'll see file named FLASH.NBF
- Open FLASH.NBF with a hex-editor like XVI32, and cut off first 3432 bytes. Then save file as FLASH.DIO.
- Now you can do a flash with this .DIO file and a micro-SD card, or with DNW tool at first post.

Great, thanks Paloma!!!

ipaq 614c resurrected with this great util.

Thank you.

P.D. Hp repair cost me 246 euro replacing all mainboard

Paloma, i have the same problem, but with a ipaq 6915. It is always into initial screen with blue screen and HP logo and in the botton right corner saying "No GSM" and ROM version. I would like test this solution, but when i run UBOOT the program always say, "Can´t open USB Device". I have installed the driver and it still saying the same.
Other cuestion. When you say "Download Mode" it is the same than "Bootloader Mode"?. Thanks

hi Carlengue.
This solution isn't apply to HP 6xxx.
I've got some ideal to help you, but now I ca'n 'cause I'm not at home, without my PC/laptop. I'll PM you later, ok?

i can't find the proper key combination. I've ipaq 914c

@ Carlengue:
Follow this link: www.mediafire.com/paloma and goto folder PPC tool. Download Uni_exitbootloader and run it with your phone plugged and active-sync disabled. Then you can try with one of two ROM I've uploaded (I don't know wich device you have, G3 or G4)
@ Ericco: I'm verry sorry, I'm in traveling and cannot find a HP-9xx now to test combine key for you. Can you try with VOLUME(up or down) + Record (or Camera) and Power (or Reset).
I'm sorry again about this incompatible.

Still can't find the proper combination.

Ok. I found it

Volume UP + OK (on side) + Reset

Rom on my 914c changed from NDL to ENG yeah

Hello Paloma,

Thanks very much for this info.

I have not used it yet but I can appreciate the knowledge since I had a bricked 612c previously and had to wait for 2 weeks for it to be fixed, I tried various software at the time but couldn't get to work.

I would like to kindly ask if you could please explain to us how we could modify a flash.dio or build a custom one. I want to know how I can modify Windows Startup files and decide on what software I want to have installed by default, etc... (that would be greatly appreciated).

Thanks heaps
