[Wing, P4350 General] mkoz:
I don't take the responsibility for any damage caused by the information included.

This is not my intention to reveal any secrets of HTC Company. All this information was known earlier. I've just collected it in one place and used it for repairing my broken HTC device.

Although it was successfully tested on Herald from Dopod, it should work on any Herald and as far as I know this is the only hope, especially for Heralds with low SPL number, broken by flashing with HardSPL

If you find this tutorial useful, do it on your risk.

I've spent a lot of time in searching of a solution for my bricked Dopod C858. It has been bricked after Hard-SPL by Olipro. When this Hard-SPL was first introduced, there wasn't any warnings about minimum SPL and GSM versions requirements. That's why there is a lot of people with their Heralds stuck in the bootloader mode without a possibility of successful flashing in any way.

One of the symptoms was Invalid Update Tool 300 Error when I was trying to flash even with the official RUU. The other symptom was "GetDeviceCID: Error - InitDecoder" when getdevinfo command was typed at MTTY console.

Finally I was able to recover from this state. I successfully created the goldcard - a micro SD card with the special header, which gives us a temporary SuperCID status (security level 0). In this way we are able to flash the new ROM via SD card, instead of using the official RUU (ROM Update Utility). If it is not enough to flash successfully, we can use a wonderful service tool included in Herald's diagnostic image (heradiag.nbh).

All the credits goes to "itsme" and his hard work. It wouldn't be possible without his knowledge, his help and his great software. Willem agreed to make this tutorial and share this knowledge on the forum.

Thank you Willem!

I would also like to thank "pof" for his effort and although he couldn't find a solution, he tried to help me, so thank you Pau!

The other person I would like to thank is "canonyang_China". I know he is accused of stealing Olipro's ideas of Hard-SPL. I only want to thank him for posting heradiag.nbh file. This is the great tool which together with the goldcard can do a lot.

I would also like to mention one person. It's "jockyw". He has almost identical solution but he has found it by himself. If you find this tutorial too hard to deal with I recommend to contact "jockyw" and he will help you for a small paypal donation.

TUTORIAL:

***********************************************************

Requirements (not tested on other configurations):

1) Windows XP with SP3

2) ActiveSync 4.5

3) ActivePerl 5.8.8.822

4) Crypt-DES and XdaDevelopers-NbfUtils PERL packages

5) typhoonnbfdecode.pl PERL program

6) itsutils tools

7) working mobile device with any Windows mobile OS (2003, 5.0, 6.0)

8) any .nbh ROM file from the official Herald's RUU

9) heradiag.nbh file

10) micro SD card (tested on 512MB and 1GB)

Ad.2) download your language verion of ActiveSync and install it:

Ad.3) download and install MSI installer of ActivePerl 5.8.8.822 from http://www.activestate.com

http://www.activestate.com/store/download_file.aspx?binGUID=e5c71329-b7a6-4563-8199-e1483f751c4f

Ad.4) run Perl Package Manager from Windows Start Menu

change PPM Preferences (run Preferences from the Perl Package Manager menu and switch to the repository tab):

- Add repositories:

Name: itsme

Location: http://www.xs4all.nl/~itsme/projects/perl/ppm

- Add repository:

Name: theoryx

Location: http://theoryx5.uwinnipeg.ca/ppms/package.xml

After database synchronization install those packages (at the main window of Perl Package manager find those packages, mark them for install (the icon with green plus, next to the search bar) and run marked action(green arrow icon)):

-Crypt-DES

-XdaDevelopers-NbfUtils

If you can't find those packages on your list, please make sure you have selected "All packages" from "View" menu in Perl Package Manager main window.

Ad.5) download typhoonnbfdecode.pl from http://www.nah6.com/~itsme/cvs-xdadevtools/xda2nbftool/

Save it to "C:\itsutilsbin"

Ad.6) download itsutilsbin package from http://www.xs4all.nl/~itsme/projects/xda/tools.html. Unpack it to "C:\itsutilsbin"

http://nah6.com/~itsme/itsutilsbin-20080602.zip

Ad.7) Find a working Windows mobile device and use it to format your micro SD card as FAT32. It's important to do this on working mobile device with any Windows mobile OS (2003, 5.0, 6.0) because PC USB card readers causing troubles with making a goldcard because of a different MBR interpretation.

- Activesync your working Windows mobile device with SD card inside

- On your PC enter windows command mode (Start->Run... cmd)

- Choose your itsutilsbin directory (cd C:\itsutilsbin),

- Run this command (l means a letter 'el' - not a digit 'one'):

psdread -l

If you have problems with running psdread -l you probably have problems with the security configuration of your mobile device. There are many options to change it. In my case I was using Device Security Manager PowerToy for Windows Mobile 5.0

It is recommended to save your security configuration, then change it to the Security Off level and after the whole goldcard preparation process, load saved configuration preset if you don't want to leave your Windows mobile device Security Off. You should have your mobile device ActiveSync with your PC when you are using this tool.

- If everything went OK, look at the result at the cmd window after psdread -l and find something like that:

remote disk 1 has 1984000 sectors of 512 bytes - 968.75Mbyte

SerialNr: 75 63 00 49 8a f2 00 80 47 31 30 55 53 44 53 03

- in the next step you will have to replace the first byte ( in this case '75' ) with '00' and write this ID without spaces between numbers - this will be your

modified cardid

In this example your

modified cardid

will be 006300498af200804731305553445303

(Thank you "hookcard" for reporting troubles in this step)

Run this command, where <cardid> is your

modified cardid

:

perl typhoonnbfdecode.pl -p cardid=<cardid> -p keys=tornado -p seclevel=0 -d goldcard.img

- Your goldcard image will be saved in your current directory (C:\itsutilsbin)

- If you have error message connected with msvcr71.dll file, please download this file or try to find it somewhere on your system partition and then copy it to the directory containing typhoonnbfdecode.pl (C:\itsutilsbin)

Then repeat the previous step with running typhoonnbfdecode.pl

If everything went OK, run this command, where <number> is a number under which you have your SD card during psdread -l command, for example, "remote disk 1 has 1984000 sectors of 512 bytes - 968.75Mbyte" means that your <number> is 1:

psdwrite -<number> goldcard.img 0 0x120

Now you have a card which gives you SuperCID - you can test it with MTTY and see that g_cKeyCardSecurityLevel = 0

Ad.8) Remember to have more than a half of the battery capacity available before you start this step!

- download any official Herald's RUU and extract it to the directory, where you should find RUU_signed.nbh ROM file. (It was tested with Dopod's ROM). Copy this .nbh file to your goldcard changing its name to heraimg.nbh

- Enter the bootloader mode. When you will see on your Herald's screen the question: "Update SD image?" you will have 10 seconds to press Volume Down button and this way to start flashing

Unfortunatelly, if something will go wrong and i.e. you will see SD update failed you will have to use heradiag.nbh file to enter special menu during the start of the bootloader mode. If you have problems with flashing, please read the step below:

Ad.9) download and unpack heradiag.zip file from this thread:

http://xdaforums.com/showthread.php?t=332413&highlight=heradiag.nbh&page=6

Remember to have more than a half of the battery capacity available before you start!

- Copy heradiag.nbh on your goldcard together with any official .nbh ROM from ROM Update Utility from the previous step.

- boot your Herald in bootloader mode and you will see the diagnostic menu where you will have Reflash Image option. Choose Reflash Image and after the flashing process (about 5 minutes) please softreset your device.

That's all! You should see your Herald properly booting Windows OS.

Good luck!
