What does it do with the raw files of the dumped ROM??

---

I have begged my friend to dump the HK local ROM (from 838pro) for me. I have a Taiwanese CHT9000. After reading the previous articles, it seems that the files in my hand (3 raw files) cannot flash the ROM into my CHT9000. Is that correct? So, what's the purpose of dumping the ROM?

Sorry...I am the beginner here.

Is it possible extract a ROM from a device and convert it to a flashable ROM? (to have a Backup or to flash it on another device)

Short answer: No, it is not possible.

Long answer: A ROM consists of 7 parts:

1. Extended ROM
2. OS Image
3. IPL (part of bootloader)
4. SPL (part of bootloader)
5. Splash screen
6. HTC Logo (normally uses the same image as the splash screen)
7. GSM radio code

You can dump the original rom, but only the things contained in the FLASH will be dumped, this does not include the IPL, SPL, splash and radio parts, so its unuseful for flashing it back.

Theoretically: if you would have the private keys for one of the 3 certificates stored in the bootloader, used to verify .nbh files, you would be able to create your own .nbh file, and flash it.

Hi pof,

Yes. I have read that. So, what's the answer? What does those raw files do? What's the purpose of getting the FLASH dumped? For development?

I used them mainly to see diffs betwen roms / vendors OS bundle and extract files from ROM. You can make a modified OS image out of a dumped OS rom, so when we will be able to flash our own code (see SD-image flashing on the wiki) you can delete unuseful files (help, images...) and add programs directly to the rom... but there's a lot of work to do until we reach that, and very few people can help in the research

Hi
I have another problem. I have dumped my MDA Vario II German ROM and extracted the Part02.raw.
If I try to use the extracted .cab files, the installation fails. Even I can't open the .cabs with Winrar.The files are damaged.
I've tested it with an other Part02.raw from the Developers FTP with the same result.
What's wrong ?

It semms, that the ROM dump ist useless.
Even, you can't use the midi and wave files.Also bmp and jpg files have the same problem.
Couriosity is, that some files work and most not.
I think it's the same problem with other parts of the romdump.

Hey guys

I dumped the black2.5 rom, hoping to make some modifications to the unlock app. Now I have a .raw image, but I am a little unsure as to reading it. I downloaded duttys koch, but I dont think that was the right approach. Im not seeing anything on the wiki, and my searching has brought me here. Can anyone point me in the right direction? Thanks.

@peezy:
Here's how to reconstruct a dumped rom:

But in your case, you have the NBH, so no need to dump & reconstruct, you can work with it with tadzio imgfs tools + bepe's packagetool.

Hopefully a little humor won't get me in trouble, but with dutty's koch, tadzio's tool and bepe's package - you should have everything you need

@pof thanks a bunch!
