Custom ROMS Possible?

[s4vva]

Given that crossbow is now floating around out there I was wondering if its possible to cook your own ROM for the Herald? I would happily start researching cooking ROMS etc. if it is. Or are we faced with a situation similar to that of the hermes where we need to find a bootloader that allows the flashing of unsigned code?

[meisterlampe2000]

Hi,

i think the Problem is that Herald is not so popular as the Wizard and Prophet by now....

Let´s ait and see when someone is getting this nice one unlocked !

[pof]

you are in the same situation as the Hermes.

AFAIK all devices using NBH for rom upgrades, need the upgrade file to be signed, otherwise bootloader won't flash it.

thanks for the answer (not the one i was looking for though!), i noticed in your hermes thread that you managed to get your hands on the bootloader from a pre production hermes. has this helped? should i be looking for the equivelent for the herald?

[pof]

It helped because it has the commands to flash unsigned code... i don't know if preproduction bootloaders in Herald will have the same "feature", but it may be handy if you can get one too :)

[s4vva]

I can try looking but i wouldnt know where to start! any advice would be appreciated.

Bootloader of Herald is similar to that of prophet and wizard.The only differrence now is the nbh format.One needs to check if awizard work or not?Then we canthink of debranding.I am working on the Bootloader of herald.Will post everything in Wiki.Pls wait for some time

Thanks to aWizard v 1.3 beta2 and POF for making NBH extract..
I was able to flash my herald from 1.7 dopod asia to new HTC 1.8 without changing/touching IPL/SPL.Here is how to do :

1)Use POF's NBH extract and extract the ROM parts.
2) Copy the OS.nb to awizard ROM folder and rename it to.nba
3) From the Lib folder of awizard, transfer enable rapi and certsps cabs to yr device and install them.
4)Now run the batch file and select "e" to enable rapi.
5) Then you can directly choose the option "w".This will give you the option to choose the ROM u want.Select and wait till awizard finishes.

One can also back up the Extended ROM, Splash image, bootloader, Radio and OS ROM with awizard.
It is very interesting that the size of the .nb file extracted from NBH file and the size of the wizard ROM(80040000.nb) is exactly same.
I tried to put crossbow image into it..but I clouldn't boot the herald.The boot screen showed "OS 10.1.00.88

So if some one can extract the things from both the .nbs we can think of having crossbow in herald..and I think POF can do it.


I hope, this helps the members to upgrade and play with their toys.

[keremk]

Finally !!!! Did it. followed the instructions and wallaa finally dutch rom Bye bye bye and Hello English Rom.
Thanx Guys you rock

Look'n forward to crossbow soon.

[pof]

Very nice discovery hdubli!! :)

Unfortunately I don't have Wizard nor Herald, and I have not much experience in ROM cooking... you should ask the real gurus here if you want to port the Wizard's xbow to Herald.... I saw it was ported to Prophet, but I don't know about the internals of Herald and Wizard enough to say if this can be also done here or not.

Anyway, kudos for your finding! ;)

P.S. You should add this info to the wiki!

[s4vva]

well done hdubli, this is serious progress!

[s4vva]

I have no experience of ROM cooking, however I have both a Wizard and a Herald, so if I can help in any way just let me know.

[jaikben22]

looking for a bit of guidence here

i have the herald 1.8 ROM as .nba (taken from device using awizard)
and i have the wizard OS I want to use as .nb (extracted using typho5)

now my understanding here is i need to extract the herald drivers from the herald OS and replace the wizard drivers in the wizard OS, rebuild the OS.nba and write it to the herald using awizard. Am i heading along the right lines or am i way off? any help would be appreciated.

[jaikben22]

I do the same thing as you did, tried to put crossbow image into it, and it boot up and freeze at the start screen, so now I have the problem, how to put the old OS back?
I have back up the OS ROM, but my machine can only boot into the tri-color screen, how did you do on your machine, please tell, it will hellp me out.
Thanks

Hi pof,

I am not new to ROM flashing, but I've never used awizard to do it.
I have extracted and renamed the OS.nba from the nbh file.
I've also backed up the current OS.nba from my device.
Before proceeding with flashing, may I assume that I can use the old os.nba file to restore the previous language on my Herald (just in case...) ?

Thanks.
Silver

how do I dump ROM image from a Herald and make the NBH file? From what I understand the NBHExtract only extract ROM parts from a NBH file which I assume is the ROM image.

Sadly this thread seems to have died... let's revive it if we can!

I've been doing some minor ROM cooking on my Hermes and think I understand the process for that machine. Unfortunately, my Dopod 838Pro has a hardware problem with the D-Pad and Phone hardware keys and is out of warranty so I've switched to a Dopod C800.

From some of the findings reported on this thread, the next logical step in the process of making WM6 for the Herald would be to identify the various drivers and replace them from the Herald WM5 ROM into the Wizard WM6 ROM.

Would someone help by listing the various drivers (and the specific files involved hopefully) that need to be replaced?

Let's hope WM6 for the Herald doesn't have to wait forever for an official release and let's help make this great phone more popular!

The first WM6 release will be the XDA terra from o2 (german, sorry) But it is comming the next 2 weeks.

And when someone tells me how to extract the OS (I only get used in flashing a wizard many times) I will release here, after I get the device.

I have successfully flash the WWE 1.8 ROM to the chinese dopod c858 (herald) by following the instruction! now how can I get the extended rom flashed? there is no option to write the extended rom back in aWizard.

[dkb218]

In about a month, this thread will wake up big time... All those Hearlds T-Mobile USA will sell is gonna take some light away from the Wizard fourm...

[papamopps]

Here it is:

Sorry corrupted and i deleted the link - new one will follow

[ASerg]

And what is audible about WWE the version?

How to write down new Extrom?

[Aesthete]

The solution of changing RUS-->WWE didn't work :(

aWizard don't see any OS files... any ideas? (And yes, i extracted and renamed 06_os.nb file to NBA).

Same problem here. When trying to flash with RUU it stops after 1% and says ERROR[270] and when i want to use awizard it doesn´t show any OS.nba????


Please let us create a working RUU - like they did on Hermes forum.
