1. Make sure your Treo 750 is Hard-SPL (http://forum.xda-developers.com/showthread.php?t=334100). This would allow you to install any ROM, including cooked ROMs found in this forum.
2. Download the Generic Treo 750 WM6 ROM here: http://palmone.r3h.net/downloads.palm.com/Treo750_2_23_ROW_EN_DesktopUpdater.zip
3. Extract the updater into a folder of your choice. There are two levels of unpacking.
4. Search for the CHEEIMG_FW.nbh file in the final extracted folder.
5. Put the abovementioned ROM image file into a clean FAT32 formatted mini-SD card. Rename it to CHEEIMG.nbh.
6. Insert the now populated mini-SD card into the mini-SD card slot of the Treo 750.
7. Press and hold the side media button & at the same time, use the stylus to press the reset switch. You will see the tri-color bootloader screen momentarily followed by Loading...
8. Next, you'll see a light blue screen with the heading CHEEIMG.nhb followed by a few other entries below it. The instructions at the bottom of the screen says to press the power button to continue. Go ahead & press the End Call/Power button to start the ROM flashing.
9. The ROM flashing takes about 15 mins. When it is completed, the bottom of the screen will say Update successful and the entries above with the OK appended at the end.
10. Reset the Treo 750 with the stylus & immediately perform a Hard Reset. This is accomplished by pressing and holding the End Call/Power button and simultaneously resetting the Treo 750. When prompted to Erase all data, release all the previously held keys and press the Up key of the D-Pad.
11. Once the formatting of the RAM has completed, the Treo 750 will continue to bootup & you will go through the standard startup wizard for setting up your Treo 750 for the first time.
Everything else should proceed as per normal.
I'm writing this from memory because I've just unbranded my AT&T Treo 750 & am now on WM6.1 Professional.
Please perform the abovementioned steps at your own risk. I'm not responsible for any damage that might result from the procedure.
All the best!

I tried this method and I had the same problem as you.Try this method.

1. Download the official unbranded bits here:

http://palmone.r3h.net/downloads.pal...topUpdater.zip

2. Extract the EXE file that is in the zip file (give it a specific folder to extract to, the zip file uses a funky folder name).
3. Run the EXE file, but stop when the gui pops up.
4. At the first screen, navigate to c:\Documents and Settings\your username\Local Settings\temp, then inside the temp folder you will see a palm folder, and a folder with some random numbers and letters like PQa02356.
5. Enter the installer temp directory
8. right click payloads.xml file and select edit with notepad
9.Replace the RWE carrier text with ATT if your phone was from ATT, then
Replace the high 1.16 version with 2.27
11.After you have made the necessary changes click on file-save as, then save it back into the same file as it was originally in, and save as (all files)
if you save it as a text file it won't work.It must be saved as payloads.xml
with the xml attributes.
12. Go back to the installer screen and continue with installation
13. You must complete the installation successfully, if it fails, rerun the whole process. If it isn't successful, the flash ROM isn't "closed" and you won't see the new version numbers updated, and what not else as well.
Ta daaaaa and it runs HSDPA !!!

It worked great for me. My treo was fairly new with winmo6 version 2.25 with ATT branding, and nobody seemed to have the exact directions that worked for my phone. feel free to pm me if you need any help.
Now I have the unbranded 2.27 version.It works flawlessly

I currently have an unlocked At&T branded 750 with WM 5.2 What will this download do for me? Unbrand my device or just update WM? Please understand that I am a Newbie at this. How do I upload this software to my 750 device?
