DesktopUpdate 2.26 ROW error.

[Rickson69]

Hi all,

Try to update my Treo 750 with: Treo750_2_26_ROW_EN_DesktopUpdater.exe file.
But it gives an error :mad: saying:

Unsupported Device

Important:
This updater only works with the Palm treo smartphone.

What am I doing wrong......

- SD card is Fat32, 2gB freespace
- just fired up the exe file

And then the Unsupported Device.....:confused:

My Treo 750v is allready unlocked (got T-mobile now)

Hi all,

Like you could read, i couldn't upgrade using Treo750_2_26_ROW_EN_DesktopUpdater.exe file.

http://www.filefactory.com/dlf/f/641510/b/4/h/6af69e22285ac86cec78ef60a3145bc3cbc2b3bb/j/0/n/Treo750_2_26_ROW_EN_DesktopUpdater_exe

But it finaly worked, so i thought i'd share the welth with the one who also want to upgrade and didn't succeed, this is how i did it.

Step by step.

1. Unpack Treo750_(version)_?DesktopUpdater.exe
2. Find CHEEIMG_FW.nbh (it's about 83MB).
3. Format your card to FAT32 (using Windows and card reader).
Make sure that this is FAT32, not FAT(16).
4. Copy CHEEIMG_FW.nbh to formatted miniSDcard.
5. Rename CHEEIMG_FW.nbh to CHEEIMG.nbh
6. Put your miniSD card into your Treo. Plug charger into Treo.
7. Holding PPT/Media button (one under volume keys) + push reset
(under card slot) with stylus.
8. You should get bootloader screen (red green blue).
9. If you made previus steps right Treo should ask if you want
to flash rom.
10. Press power button (red) to confirm.
11. Watch progress bar while Treo is being flashed
(it will take about 10 minutes).
12. After upgrade make hard reset (reset + holding power button,
then "up" to confirm).

So this did the trick. :D (for me)

Now i'm on wm 6.0
Planning to upgrade to 6.5 :D

Did you Hard-SPL first?

If you did first Hard-SPL and then the steps then it should work.

Which upgrade did you do, wm5.0 -> wm 6.0/6.1/6.5??
