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:
http://wiki.xda-developers.com/index.php?pagename=Hermes_HowtoReconstruct

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!

Hi everybody,
I just bought me a TyTN and did the Rom reconstruction procedure, this all worked very well (thx for the great guides), but with this procedure only the Part02 file is transformed into a .nbh file.
Is it possible to fully reconstruct the rom including, splash screen and most import the extrom. I still have all the four Part00 - Part03.raw files but don't know how to convert them to usable .nbh files, I also don't know what the other three PartXX.raw files are.
Cause at the moment when I load the reconstructed rom, I have the extrom from the last rom I had installed which of course is not the extrom of the reconstructed rom.
Any help on this would be great. Thanks.

Please read exactly what I'm asking for
@peezy: before shouting wiki, you should read my post exactly. I already succeeded in building an OS.nbh from my dumped ROM.
What I'm asking for is a FULL rom reconstruction, especially the extended rom is a problem if missing and I'm quite sure the extended rom and maybe also the boot images are in the other PartXX.raw files but I don't know how to create the missing .nbh files for flash and extended rom. What's not such a big problem is the radio rom. But in case I have to repair the phone I'd like to go back to the OS I had before flashing the WM6 LVSW including boot images and extended rom.
I already found a thread on how to create the boot images, but the problem is I have to pull out the boot images from the dumped ROM and the even bigger problem is the extended rom which I also have to reconstruct from the dump files.
unhide extrom, copy the files and use AnDim ExtROM editor to create your new extrom.nb. See stickies in this forum for more info.
For splash screens see here:

stuck with splash dumps
@pof: Thanks for your help, I was able to create the ExtRom with AnDim ExtRom editor and I tried to extract to splash screens with mtty and usbmonitor.
But I got stuck there because USB Monitor is kind of strange to handle if you don't know what you're doing, so I tried to extract the dumps on my gentoo box. At first with your supplied 'cu' command but that fails for what reason exactly I don't know. So I used ser2net to made my ttyUSB1 accessible with telnet. And then I did a dump of my telnet session with the rbmc command one for each splash screen.
Can you please explain what I have to do in order to get the .bmp's out of the dump files? I assume at first I have to clear out the telnet command lines at top and bottom, but I don't know exactly up to where I have to cut the files and how to convert the resulting file into bmp. Cause I'd like to dump the images from a colleagues phone (which has special boot images and no downloadable rom upgrade).
or maybe you can give me a correct 'cu' command for dumping the stuff directly without having to capture the telnet session.
Thanks for you help
@marcelser: just remove everything before HTCS, and everything after HTCE. Then you have HTCS +262144 byte splash screen + 4byte checksum + HTCE.
So remove HTCS, 4byte checksum and HTCE and you have your splash screen in NB format
It worked
@pof: Thanks for you help. Made a little perl app which grabs only the portion between HTCS and HTCE minus 4 bytes at the end with a little regex and writes that to a new file.
Then used rombaker to make a new splash.nbh file and re-extracted the files in the new RUU_signed.nbh with nbhextract which also converts the extracted .nb splash images to .bmp and the .bmp's looked just fine.
Then I loaded a different wm6 rom which has other splash screens and flashed the RUU_signed.nbh with the created splash screens to the device and had the extracted splash screens back on the device.
I attached the perl file which converts any dump which has the HTCS and HTCE strings in it to splash .nb it should run on any perl version (win32 + linux) although its only tested on linux.
was wondering if someone could tell me where to find the nk.nbf from dcd's 2.2.x roms...want to cook up some custom boot screens, but have NO idea where to find it (or get it from). thanks
You need to extract the nbh from the installer (you can use procmon from sysinternals.exe to find out where the installer extracts it).
After that you need to decompile the NBH using various tools, in which will present you with a 00_OS.nb.
After doing that, you need to extract the splash images from other roms, or create your own, then recompile the NBH.
EDIT: wow first post since 2006, you can tell ive been a leech, glad to give back to the community lol...
I was going to post the contents of the readme file that i'm trying to understand...in order for you to see what i'm being told to do, but I really can't decipher it all that well, so i'm going to attach it. This is what I'm being told to do...
Have you looked in to this: http://forum.ppcgeeks.com/showthread.php?t=16939
Yeah I read through that...
Thing is...with dcd's latest roms, the only file you get when you extract his nbh is 00_OS.nb
I have my splash.nb already made from the image i chose, but I'm not sure what to do with 00_OS.nb and splash.nb
Make an NBH from them.
You can use Dutty's NBH Tool patched for the Titan.
Since I can't find the original thread where I got it (took me forever to find in the first place) I uploaded it to fileshex.
Download here
I don't have to name my splash.nb something specific when creating the new nbh? It will just know that it's the splash?
Edit: nevermind, after opening duttys tool it's clear on how it works...thanks
Ahhh..one more question...
Is it possible to just take my splash.nb and make an nbh out of that. Then put it into the RUU and flash just the splash? Or must it be merged with the entire rom and flashed?
I have no idea.. I never did it. I want the original Verizon splash screen back instead of the static Verizon logo.
Try it and let us know if it works.
Can someone upload VZW_Startup.gif from \Windows somewhere I can download it?
I'd appreciate it very much
Confirmed.
Just took splash.nb and created an nbh just including the splash fields. I then inserted it into the RUU, flashed, and worked like a charm, no need to include any other part of the OS or anything.
Looks badass...for any help let me know...now that I know what I'm doing
P.S. It WILL hard reset the phone though upon flashing...
I put all the necessary files in a zip and I'm working on an easy step by step readme...so if anyone wants to change their bootscreen send me a pm.
I have withdrawn inside i780.bin document nb0,Has made some revisions, finally has produced new nb0,BUT how the nb0 return to original state is bin?
Hi, sorry if this is not the right place.
Recently bought new device, made a copy of my pictures to PC and then copy them back to new device, point is that dates were changed to day of copy.
Image names contain caprure date as this img yearmonthday-numberofpicofday, for example
Img20190202-w0000001. Is the pic number one shot on february 2nd, 2019.
Is there any soft to extract dates and change capture date from image name? And capable of doing that in batch, we are talking about thounsands of images.
Before any answer, I am concern that extracting from exif is a possiblitie, but senseless for me cause exif data is gone from my images.
Tbahx in advance
