how to unlock rom on treo 750v - made by htc

we are trying to unlock and or dump the rom on the treo 750v. this is a newly released treo made by htc. the treo has an awesome feature called theeaded sms which does chat style sms.
we have tried the grab it program that was on this site with no luck.
does anyone no of a way to get this done? does any have any ideas of why the grab it program doesn't work. does anyone want to help?
thanks, cody

So far we've manage to get someone to try the grab_it tool from
http://forum.xda-developers.com/showthread.php?t=238945
But they are getting a write error. I assumed since the Treo 750v uses a mini-sd card the appropriate version of grab_it would be grab_it_128_minisd_468.exe. I'm trying to get someone to try the grab_it_128_150.exe version to see if that works, since that is the version BeyondTheTech used to extract the Treo 700w rom. The 700w uses a regular sd card though.
I asked the guy that tried grab_it_128_minisd_468.exe what the storage card folder name was set to and they verified that the registry was set to "Storage Card". So it's unclear to me why they are getting a write error. Maybe the minisd version expects something else? The card used was a 2GB minisd so it should have plenty of room for the rom.
Anyone familiar with grab_it know what is different about the minisd version? I read through the thread but it wasn't clear to me what the difference is.

Ok, I'm the one who's run the grabit tool on a 750v
It runs Ok and creates a 128Mb dump.bin file but the file appears to be mostly empty. If I zip the file up it only takes 147Kb which seems to confirm this. Am I doing something wrong or is it a bug in the tool

i have hope 750v user and appreciate your efforts

Can you upload the bin file please. I think someone here may be able to figure this out by looking at the contents of it.

If anyone has a source for a unlocked 750v let me know i really need one.

File and registry dump.

Hi, please can you do me favor? I have idea which can help us get SMS threading application and other palm features as well. If isn't possible dump ROM in this moment can you download Total Commander (freeware) http://www.ghisler.com/pocketpc.htm and do following.
1, Create foder on memory card and go to the Total commander.
2, go to the root of your device and copy to SD everything what is possible specially from Windows folder and Program Files (rest will be fine as well)
- this will take some time and in case of problem with file just skip that file.
3, When this will be done please go into the "\\" in the root and then to "registry"
4, now select registry tree one by one and copy again to card.
This will give us most probably files which will be required for hack and registry keys which will be required as well i think.
Thank you very much for your help.

Here's a zipped up copy of the dump.bin file, hope it helps

I extracted that dump.bin and it looks like a 256 byte block of data that is repeated at each 16 meg boundary 8 times.
Does this ring any bells to the experts?
The only readable text is "CHEETAH IPL EVT".

wow! that's great!

I don't have a Cheetah, but there's some info on the hermes forum that might be of interest to you:

750v_User please try this program to extract the rom image.
unzip and copy TestDump.exe to your device and run it. In the "Path to file" enter the path for the dump file (i.e. \Storage Card\dump.bin). In the "Mbytes to dump" enter 128. Then press the "Dump" button. It should make a dump of the ROM file.
Zip it up and upload here. Thanks!

Thanks. That post appears to be for updating the rom. I wonder if there is some key combo like this to extract the rom.

Based on the Hermes experience, there's no knonw way yet to extract it in a form that after is flashable on another device, but you can follow these instructions to dump some parts:
http://wiki.xda-developers.com/index.php?pagename=Hermes_HowtoDumpRom
You can also use pmemdump to copy some of the ROM contents to a file. Once you've dumped SPL you can search for strings on it and you'll see the bootloader commands.
HTC has removed all the "d2s, s2d, r2sd..." and like commands in the hermes bootloader, probably you are lucky and you have some command to dump the rom to sd in your bootloader.
Hope that helps

The ROM dump // extract discussion is over my head...one question though has anyone sorted out how to unlock this device?

750v ROM dump uploaded
I put a rom dump from the TestDump.exe tool on ftp.xda-developers.com. userid: xdaupload pw: xda
file: treo750v_dump_rom.zip
I used the dumprom tool to extract files, but it looks like it's only extracting the first rom section it finds and stops. Can one of the experts take a look at the dump and see if you can extract the other sections please.
Thanks.

What are you getting from the first rom section?
Sounds weird... was the dump complete?

It looked like a bunch of system files. The kernel, img.dll, filesystem drivers and the like.
There is 59MB of data in the dump so there has to be more stuff in there.

WM6 upgrading without the baggage

Hi all, I have downloaded the WM6 upgrade form Palm but when I run it insists that the device is not compatible. I've put this down to a flaky software from Palm unless you know differently....
So my question is, can I extract the CHEEIMG_FW.nbh and install it without all the baggage that comes with the Palm installer?

yes you can
that's what I did

Since my original post the nice poeple at Palm have fixed my problem and sent me a fresh install file for my VF UK 750V.
All installed and working fine now.
Let me know if you need the VF UK upgrade.

yes sure could you send it.
thank you

you can use winrar to extract the file that you need from the executable file you had downloaded

Hi, Is an "all new install" or upgrade?.
I install the VF upgrade and working fine, but I discovery that some files of an "unistalled" applicaction stay in \Windows folder. Maybe un "clean install" delete it ¿Can you share whit us?
Thank

Unlock help really needed

Hello people,
I bought an Imate SP5 from ebay and its from Orange. Now I need to application unlock it.
I know I know, first thing you will say is search older topics, which I did and its driving me crazy, here are the things I have already tried and nothing worked-
http://forum.xda-developers.com/showthread.php?t=330291
In archive three files.
The names begin with 1,2,3
In this order start all three

1) Simply put the *.zip file with the regeditSTG.exe in it with ActiveSync into a folder on your phone (but not onto the memory card).
2) Unzip the file with the *.zip program that comes with your phone.
3) Now start regeditSTG.exe and change the following Registry Keys...
I even downloaded an external registry editor and manged to change the registry values but it still did not unlock the phone.

Download this application.
1: Run program htcunlock cvs on PC
2: Find program that is created on your phone on the startmenu in on device
3: Run exe and cross fingers (It changes settings in registry, wait for the Smiley!)
4: Powerdown and Powerup!
And any other SPV Unlock applications. But they all fail since its pretty tightly locked. I can't run any third party applications.
I think the only thing left is maybe do a ROM update but I have no idea which one to use and how to go about doing it.
Please advise me on what I can do or send me in the right direction. I will be really grateful!
Thanks.

OK, I don't know what was it, but I tried running SPV Services and it ran successfully and let me set the SuperCID and I was able to update the ROM.
So I guess one of those earlier methods did work!
Thanks anyway and just want to say that I really appreciate the members of the community that work so hard to make our phones much better and more useful.
Here is a big vote of THANKS for you guys!

AT&T "Bloat-ware"

Does anyone know where i can find a listing of the at&t cab files in the windows directory that are installed during the initial start-up? Im just looking to see which cab files install was, such as the mall, or music, for example. Not that i plan on needing them but after searching the internet for a couple days now it would be nice to learn how to bring the phone back to at&t specs. Thanks.
Greg

You can hard reset and not skip the bloat or you can go into the windows directory and sort the files by their type.

But what if you want a couple at&t programs on there?

1. Open up File Explorer
2. Go to the /Windows directory
3. Sort files by type
4. Locate the .cab files
5. Choose which apps you want to install

If you are trying to bring the phone back to ATT spec (to sell or to send it back for support), the best way is to flash using an ATT stock ROM. They are posted on the ROM development forum, here is one on the front page. Since its an official ROM you dont have to mess with HardSPL or anything of that matter, it should just flash the phone.
If you are trying to get the best performance out of your Fuze, I would suggest flashing your phone with a custom ROM.

How to downgrade with official desktop updater!?

Hey,
I tried to pot my Treo back to WM6 from Vodafone with the original updater, but it keeps telling me that my device is not supported because of language issues (Right now there is WM6.1 working on it in english and I need to flash the German WM6). when I open the installer with WINRAR I can see a couple of *.nbh files (cheeimg.nbh and cheeimg_fw.nbh). Is it eventually possible to just take one of them and flash it? or do they anyway require to have a preinstalled stock ROM to update with them? And why are there so many other files in, when i usually actually just need one nbh file as a rom?
Thanks for helping me understand my phone

bump
i d like to know that aswell. did you fixed the issue by now?

If you want to use the official updater you need to modify the payloads.xml file.
You can find it by opening the official updater, but don't start the upgrade. Opening the updater will extract a bunch of files to your TEMP folder. The payloads.xml file will be in one of the subfolders. The folder is called something random so you'll have to seach for it, but you'll see a bunch of Palm icons in it so you'll know you're there.
You can edit the payloads.xml file with any text editor. Notepad works fine.
If you are changing carriers as part of the update, you will probably need to change the carrier code to the one matching the currently installed ROM. This is AT&T, for example.
Code:
<carrier_codes>CNG,ATT</carrier_codes>
I think Vodofone is VF, but you'll have to do some searching to confirm that.
Then you need to change the revision range to allow the downgrade.
Code:
<revision_range>
<low>1.13</low>
<high>3.00</high>
</revision_range>
Save it when you are done, and then start the updater. It should work. If not, there are plenty of posts here about downgrading ROM's, so search around until you find something that works for you.
And yes, you can extract the ROM's from a desktop updater and flash using the SD card method, assuming of course you have successfully HardSPL'd your phone. You need the CHEEIMG_FW.nbh file, but must rename it to CHEEIMG.nbh before putting it on the SD card.

You don't need to Hard-SPL in order to flash official Palm WM ROMs from a MiniSD.
