[Wing, P4350 Herald Upgrading] fishwiz45:
this guide really helped me when i started flashing

PAY SPECIAL ATTENTION TO STEPS 3. 3A,3B,3C...

1. Download which version of Touch IT you want. For the Last version made, here is the link: http://xdaforums.com/showthread.php?t=340403

2. Backup any information you wouldn't want to lose. Either backup to memory card or PC; your choice

3. At this point, You need to install the official RUU for your device, if you're already running the official RUU, then you need to hard reset your device. (Press and hold both soft keys and press reset button, continue to hold softkeys til screen displays to hard reset. Press the call button to continue). If you need to install the official RUU, continue to step 3a4Here is a list of uploaded RUUs

3a. Enter bootloader on your phone (Hold camera button and press reset, continue holding camera until a screen with 3 gradient colors shows up

3b. Connect your computer via USB to your ppc (Pocket PC)

3c. Run the RUU .exe from your hard drive, follow its simple onscreen instructions and click check boxes necessary to continue with the installation. This should take a few minutes, and you will more then likely see your screen flash and change things, this is normal, let it work. After a few minutes it will boot up and go into "automatic customization of your device", I continued this (screen alignment, tips, auto setup), and waited for my device to be totally ready for me to use.

4. Connect your device via USB to the PC and wait for activesync. If it automatically pulls up a profile for your phones sync, delete that profile. If it asks again to setup device for syncing items, click cancel. You will still be able to explore your phone and install devices without setting up the sync profile for your phone.

5. Make sure your phone is connected as a guest, if it is not, make sure it is. The method I used to do this was this zip file I ran "guest only" registration entry. (Make sure and run allow partnership registration after completing installation), but it should display as guest after the hard reset.

6. Copy aserg policies.cab to your mobile device

7. Run aserg policies.cab from your device

8. Soft reset (use stylus for button on side of wing, or on bottom of herald)

9. Go into your comm manager on your phone, and disable "phone". Basically enter flight mode so nothing can be sent to your phone during this process.

10. Once booted, its time to give it a shot. Make sure you're still connected as guest, and run !Upgrade_rom.bat from Touch_it folder on your PC

11. This will bring up a command prompt waiting for you to hit a key to begin, press any key

12. During this time it is installing, NEVER touch your phone or play with it in any matter. It may look as though the command prompt has gotten hung up at times, but leave it run until it completes (or fails). your phone will pop up a message saying "unknown status" or the likes, but dont close that window, like I said just leave it alone.

13. If you have no error messages in the command dialogue box then you're ready to hard reset your phone. (press both softkeys, and press reset, continue holding softkeys til you see a dialogue asking if its okay to restore settings, hit the call button to finish it)

14. Your device SHOULD boot normally, go through setup, and you should be golden.

If at any time there is an error during install, but you still let it complete, you might have a chance at it working. Hard reset it after completion (even with errors) just to see if it works. If it wont go past your Tmobile or HTC picture screen on bootup, then you have bricked your device. To UNbrick it, run steps 3a through 3c and reinstall the RUU.

If you get any errors, try and try again. Its proven working on several devices.
