What you need to know
First off, flashing your rom is dangerous. Not blow-up-the-world type dangerous, but you're-out-500-bucks dangerous.
If you brick your phone (render it useless), it's your own fault. At this point the ROM is still what I would consider 'unsafe', in other words it's not at the point where you can follow steps 1 through 10 and achieve success.
Additionally, flashing your phone is completely unsupported by either Palm or your wireless carrier, and may void warrantees, insurance, etc, etc, etc.
I've only tested this with Sprint. Verizon and any other carriers may or may not work, try it at your own risk.
How to flash your phone back to standard settings (stock ROM)
The basic method of flashing is essentially the same for any rom (at least with the Sprint update). This is the method of flashing your phone to standard/default settings, allowing you to (hopefully) get back to a standard rom should something go wrong. This is not 100% guaranteed, and may or may not work depending on how badly the flash went wrong.
- Download the (Sprint) SD card ROM update. (http://www.palm.com/us/support/downl...installsd.html as of this posting the update is at 1.15.)
- Format your SD card in FAT32 format (any other format will most likely not work). You will need at least a 128 meg SD card, I recommend larger so you can place a few useful programs on it (such as psShutXP) on it.
- Extract the SD card ROM update to your SD card. You should see 4 files in the root directory, and a folder named 2577.
- Have your power cable handy for your phone.
- Hard reset your phone. (The flash is designed to "upgrade" your phone rather than overwriting everything. Nice when everything is working the way you like it, not so nice if it's not. If you don't hard reset your phone you may not see all of the new options. For example, I didn't see the new Wait Cursor until I had performed this step in this order, a straight hard reset or straight flash did not actually seem to clear everything.)
- When the Treo splash screen comes up, but before it starts loading: Pull the battery on your phone. (Note: your battery should be nearly or fully charged.)
- Place the SD card into your phone.
- Hold the volumn up button on your phone.
- While holding the volume up button, replace the battery in your phone.
- You will see a screen that tells you to press up on your 5-way if you want to flash, or any other key to cancel. If you don't see this, go back to step 6.
- Before you press up, plug your power cable into your phone. The red light will not go on as normal, this is expected, but assuming your power cable is plugged in at both ends and working properly, the phone is still on AC power.
- Press the up arrow on your phone.
- Very carefully (without disturbing anything) place the phone in a safe location. You do not want to move it and risk disrupting the power or accidentally ejecting the SD card. This is a good way to brick your phone.
- Wait patiently for the "Download OS + BL" screen to finish.
- Once the bar is full, your phone will reset.
- If you get stuck on the Treo spash screen, you're bricked your phone. You may be able to recover by going back to step 1.
- If you get stuck on the Windows Mobile splash screen...be patient! The first time your phone boots it will take a minute or more to load. If it hasn't loaded after several minutes, go back to step one. You've bricked your phone, but most likely can recover as it's Windows that is not loading, and not the boot loader.
- If everything is successful you should be asked to setup your phone again (including calibrating the screen). Congratulations!
- You can play around with it at this point, but you will need to soft reset it for everything to take effect (especially recommended if using a custom ROM).
Note: After you are done flashing--and your phone has reset--you may want to pop out the SD card. This seems to help decrease the amount of time your phone will take to boot the first time (This would be after step 14). Do not remove the SD card before your phone finishes flashing!
How to flash your phone with a custom rom
You will follow the directions pretty much above. The only difference is you will replace the default NapaBoth.nb0 file with your own custom one. This would occur between steps 3 and 4.
