Help with wm5 to wm6 upgrade!

[drdedos]

I'm dizzy reading all the threads, information overload, so thought I'd just post the question! This is all a bit scary and I'm a complete newbie so take it easy on me... and feel free to dumb everything down as if I were a child. :)

I live in Australia and have a Treo 750 with Software Version TREO750-1.15-ROW. It seems to be unlocked but still has the Telstra splash screen, although I use it with Vodafone. I want to upgrade to WM6, and from what I can tell I should upgrade using Treo750_2_27_ROW_EN_DesktopUpdater.zip (which I now have). Is this right? Should I skip straight to the WM6.1 upgrade? Are these official/safe?

I am running 32-bit Vista with SP1 on my laptop.

I found instructions on Palm's site here:
http://www.palm.com/au/support/treo750/downloads/wm6update.html

Are those the instructions I should follow? Is that all I need to do? I keep seeing references to the "Bootloader Method" or the "SD Card Method" or the "Cheetah Method". What are all these alternative methods? Which are the advantages of each? I've seen various different instructions, some involving renaming some .nbh file, etc. What is the definitive method?

I saw the sticky thread for the "Cheetah Hard-SPL and SIM Unlocker"... what is that utility for? Are the instructions for it in the download itself? (I didn't see it in the thread) What are "cooked" ROMs and why should I be interested? Where can I find them?

Sorry for the newbieness... thanks so much to all who respond!

If you want to upgrade to the official palm WM6 rom - then you use Treo750_2_27_ROW_EN_DesktopUpdater.zip and it is very simple - just connect the PPC to your computer . (as I know better to do it with a computer with WINXP and Activesync) , then run the program in the file Treo750_2_27_ROW_EN_DesktopUpdater.zip, and that's it.
If you want to upgrade to other roms like 6.1 normal or lite that you can find in this forum - then you need the other methods (there are two as I know - bootloader method or Kaizer..somthing method). Well, I wrote a guide how to upgrade to WM 6.1 lite using the bootloader method , I just sum up from this forum :

1. Download the rom file and the radio file:
Rom file from here : http://rapidshare.com/files/89355384/Treo750_WM6.1_WWE_Lite.rar
The radio file from here :
http://rapidshare.com/files/89336971/Treo750Radio1.54.07.00.rar
2. Download the Hard-SPL from here :
ftp://xda:xda@ftp.xda-developers.com/Cheetah/Unlocker/CheetahUnlocker.rar
3. Format mini SD card 32 FAT , using a card reader or other way.
4. Do a HARD-SPL with the CheetahUnlocker file ( step 2) . Connect the Treo with your computer using Active sync(for WINXP) and run the file. Use those steps:
- Click the Step 1.... wait the progress bar reach 100%
- Now watch the Screen on your PDA it will launch 2 times verification...
- just click YES ...wait.. and YES again.
- after finisih... wait until the activesync go green again.....
- Now click the Step 2... wait the progress bar reach 100%
- Watch the screen again... same thing.. it will launch 2 times verification.
- click YES ...wait.. and YES again.
- After finish it your PC screen will shows some popup. ignore the reading bla bla bla... about ask u to click ok.
- Just wait untill your activesync go green again.
- Now click that bloody Popup OK button.
- The unlocker app will shows up again..
- Then you will see errors saying.. continue, cancel...etc... bla bla... just click continue.. error message.. iqnore it and then just finish it.
- Now your Cheetah should be on HARD SPL mode.
5. Install the ROM :
a. Using Winrar get the file from step 1. It's name should be : CHEEIMG.nbh
b. Copy the file to the root of the mini SD .
c. Do BOOTLOADER:
1. turn phone on
2. press the MEDIA button AND at the same time with the stylus the RESET PIN
the MEDIA button is the 3rd button on the left side of the phone, under the volume button
the RESET PIN is under the MINI SD card cover
3. keep holding the MEDIA button (left side of phone) until you get the 3 color screen
Wait until it finishes. Then Hard reset the device when prompted. To hard-reset, hold the End key while pressing the pin reset button. Answer “yes” to “Erase all data” prompt.
6. Flash the radio at the same way – just copy the radio file to the mini Sd – it should be the same name. (CHEEIMG.nbh ) .
7. Download the Palm SMS file from here:(You need it only for the lite version)
http://rapidshare.com/files/99335294/threadedsms.rar
or
http://www.megaupload.com/?d=H63TXUP4
And install it as regular software (Copy to the mini SD and run it from the Treo.)
And that it all !!
Do not restore from your backup (You can restore only your data files).
Good luck !!

Thanks mate, I'm not brave enough to try the wm6.1 upgrade yet, but I did manage to upgrade to wm6 with the Updater, even though my device was "not supported". I ended up using the method where you edit the payloads.xml file before clicking 'start' so that it accepts your current device version, etc. I'm all good now.

Can anyone tell me where the AT&T Upgrade for the Treo 750 is to version 6.1. I have seen many different posts here that show many different links and different downloads with different loading instructions. Is there anything out there that is clear? I am willing to give it a try, but I am not exactly sure of which download to try. Thanks for your help.
