3 Coloured Bars on Reset Starting Upgrade.

[RockyH]

Hi,
Background:
I've been having a real issue upgrading my 750. First off none of the standard ROM desktop installers work. They all complain about it not being able to upgrade the language. I did some digging and found out I have a VFN version of WM5. That doesn't match any of the existing ones that I can see. It was originally a Vodafone UK 750, but I'm in Australia and need to upgrade. The Vodafone ones are VFE. WTF? Where does the VFN one come from?

Current Issue:
Ok I got the generic ROM, and I was following the instructions from the http://wiki.xda-developers.com/index.php?pagename=HTC_Cheetah_WM6 page.
Note about the page, it says to rename the .nbh file to CHEEIMG.nbh, but there are 2 or sometimes 3 .nbh files in every desktop installer image. I presume they mean the big one that is normally named CHEEIMG_FW.NBH.

Anyway, got the image on the mini-SD card. (yes FAT32 formatted)
Try to enter Bootloader (media button and reset button)
Now the thing just sits there 3 bars (Red, Green, Blue), and it says 'Serial' at the bottom. It never prompts to start the upgrade. It's as if it's waiting for a Serial connection rather than checking the SD card.

What can I do to get it to check the SD card?

you have to hold down the media button till the screen turns grey after pushing the reset button.

[RockyH]

Yes i did this. This is what I get AFTER the screen has gone grey and come back on.

[jhowle]

you have to continu holding it even after the 3 color screen appears

[RockyH]

ok...
forgive my ignorance...but for how long? It's been 5 minutes and my thumb is tired....

[Carl G35c]

it needs to be CHEEIMG.NBH and put on the root of the minisd card

[RockyH]

Yup I checked that. That is what it is called, and in all caps....same result.

Keep the idea coming. ;-)

Try this procedure, maybe can work: http://discussion.wmexperts.com/showthread.php?t=156093

Substitude CNG by VFN

[RockyH]

Thank you for pointing me at that procedure. It appeared promising. However, the installer program doesn't ever work because it reads the existing ROM and says "This update is intended to update Palm Treo 750 smartphones to the latest software. It is not intended to update the device language or other devices."

I need to scrub the screwed up version/carrier info from the existing ROM so this one will update it...any hints on that?

Sounds like you have screwed the bootloader.

You will need to run the recovery program to bring it back to default.
