[Palm Treo 750 ROM Development] libal:
upgrade to WM6

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 :

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 !!
