O2 IIS - how to downgrade to wm2003

HELP!!!

the link can't go

It had a typo in it. Fixed:
http://wiki.xda-developers.com/index.php?pagename=BA_Downgrade_WM5

Thanks!! I done!!

In the instructions, it says I should extract files from the rom I've downloaded... however when I double click on the .exe files (I've taken the third rom on this list from http://wiki.xda-developers.com/index.php?pagename=BA_Upgrades) it simply starts the upgrade process, and I cannot extract any nk.nbf etc.
What am I doing wrong? How do I extract the rom files so I can use MaUpgradeUt_noID.exe?
Any help appreciated!

So that means that with rar or zip you right click on the .exe and use the extract option.

Palm 750v Vodafone WM5 1.16 (For those on WM6 downgrading; or upgrading earlier)

Official Palm 750v 1.16 WM5 upgrade for Vodafone customers

http://www.palm.com/nz/support/treo750v/#software
Same upgrade as the UK 1.16. It's possibly the exact same software -- I'm just posting as it's another source for the 1.16 ROM.
[From website:]
"What does this update do?
This update provides:
Improved viewing of emails formatted in Rich Format Text (RTF)
Added support for Vodafone’s dedicated email tariffs – please see your operator for details. "

Is there any workaround for people using Windows Vista ? i hv got a update failure when flash using Vista .

I tried updating using XP and also have update failure. I only could do this extrating the rom and flashing by SD.

I extracted the updater exe. I guess I have to use CHEEIMG_FW.nbh (63,4 MB) and rename it to CHEEIMG.nbh to update/downgrade using minisd card. Am I right?
There's also cheeimg.nbh but very small (257,3 KB)...

Which CHEEIMG file?

Having downloading the WM6 update from Palm, I keep getting the Unsupported Device Error (even though it's an English Treo 750v). I've extracted all the update files from the tmp folder. Which CHEEIMG file do I load on to a card, there are the following.
CHEEIMG.MD5
CHEEIMG.NBH
CHEEIMG_FW.MD5
CHEEIMG_FW.NBH
Cheers

Rename CHEEIMG_FW.NBH (about 80 MB) to CHEEIMG.NBH and flash with it.

Cheers, that did it, upgrade successful

I put the CHEEIMG.nbh in my treo750v...push the lateral button and reset..but nothing happend.. appear 4 colour bands.... "serial" down...but NOTHING more ¿?.
Where is my mistake ¿?
Thanks in advance for your help.
Abraham
I have 1.12 in my treo750v [spanish] and I try to put wm6 [english version] I understand it is possible... ¿?

Make sure the cheeimg file is in the root of your miniSD and that your miniSD is formatted FAT32..

Backing up carrierdb.pxp...

Seeing as my hopes were dashed yet again today for the release of the AT&T WM6 ROM I've decided to bite the bullet and load the ROW ROM and be done with it. I just want to make sure that I can back up the carrierdb.pxp file so that I can restore the auto settings once I have WM6 up and running. I understand that this file is in the EXT ROM but the EXT ROM unlocker floating around seems to be for WM6 only.
If I am mistaken in my information please feel free to correct me on this. Just want to make sure I will have all features enabled when I am finished.
Thanks in advance,
David

Am I really barking up the wrong tree here?
Could some perhaps just send me/post the carrierdb.pxp from the leaked AT&T ROM?

Thanks for the link, but I already have the leaked ROM. If I could extract the files from the 04_ExtROM.nb file I'd be set. From all the my reading this does not appear to be possible without loading the ROM. Would prefer to just load the ROW ROM instead of going with the leaked AT&T ROM first. All I'd really like is a carrierdb.pxp file for AT&T. I see that someone did post the extracted ExtROM but it contains and extracted carrierdb.pxp, not the packed file. Any way to repack this or just a hint on what to do with the extracted files?
Edit: I see that the pxp files can be extracted as zips.....any chance they can be just rezipped and have the extension changed? Any particular settings that need to be used if it is possible?

Further to this, can we add another carrier in the pxp file? And can we modify the pze file?
The reason why I ask, is Fido merged with Rogers and my Treo 750 shows roaming as there is no GSM network for Fido in the pxp file. (i.e. 302-37)

Okay, I have been running the ATT WM6 leaked version for some time and recently unlocked my device and upgraded to the 2.23 ROW from Palm. Here is what I would recommend you do:
1. Upgrade your device to the ATTWM6 version first.
2. Follow instructions on this site (use the search in this forum) to "mount" the extended ROM. From there you can copy/backup the carrierdb file to your local PC.
3. Unlock your device.
4. Install 2.23 ROW.
5. Re-mount the extended rom and backup the new carrierdb file from the new rom
6. Copy back the carrierdb file from your hard drive obtained from the leaked ATT WM6 install.
Simple - if you know how to do all these things. You WILL have to spend time reading/researching on this forum to learn how to do each step, but this is the process from a macro level.

You betcha. They *are* zip compressed files with a different filename extension. Use the winrar defaults to create.

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
