Palm Treo 650 Verizon/SIM board swapout
I got this phone from a friend of mine after he dropped it on the floor too many times. It had become unreliable; dropped out several times, etc… he got fed up.
I kind of like the Palm software though…. once I saw people writing notes on the touchscreen I decided I had to try one once so this Treo needed saving.
My guess was the mainboard had a crack somewhere because slightly twisting the Treo like a wet towel could reboot the Phone. I already soldered the battery to the board because I thought it might just be the connector but no such luck.
I found a very cheap Treo for parts on ebay but it was a Verizon type which don’t have a SIM slot connector. Mine used a SIM card to connec to to a provider. The sim connector is a seperate card so I took my chances in buying the Verizon Treo and expected Palm to use a single motherboard with different addons.
Luckily I was right, when I got the phone the board swapped out without problems. I had to change the firmware to get things really working though. I found that this can be done with the use of the original Treo usb connector cable. this cable has a sync button on it and you need to press this button while booting the Treo in order to get to the ROM-upload mode.
I used the grack Treo ROM tool to upload a different Treo ROM to the phone. People from the http://www.palmclub.nl/ were so kind in providing me with a clean Treo ROM. Pretty cool… you can even compile your own ROM set with programs you use more often, or erase ‘useless programs’ to gain memory space.
After this I got me a stylus pen set and a new battery from ebay and now the phone works again. Ok it’s a big phone, but battery life on this thing is something else….
