I just upgraded my Sony Ericsson K750i to the latest firmware version: R1CA021. The actual upgrade took less than 20 minutes but I spent more than half an hour downloading the Sony Ericsson Update Service because I was also downloading a ton of podcast episodes that time.
To know the firmware version of your Sony Ericsson phone, do this (for < push the joystick to the left, for > push the joystick to the right): >*<<*<* After doing that, click on Service Info and then click on Software Info.
If you’re still using R1N035 or R1NA005 or R1AA008, then by all means download the latest firmware-it fixes the irritating USB transfer bug. If you already have R1BC002, I’d hold off for a week or two.
The only reason I upgraded to R1CA021 is because I want to blog about it as well as write about it in my weekly column on cell phones in Sun.Star Cebu. Without this blog and the column, I wouldnï¿½t have bothered updating to R1CA021 since R1BC002 served me well. I also did the update because I’m writing a blog article on how to update your Sony Ericsson firmware (check back later when I finish it).
The Esato overview on the firmware’s improvements states that R1CA021 updates the camera software version. I donï¿½t know if this means photos will be better but I took before and after upgrade photographs below so that I can compare the quality of the pictures taken.
Frankly, I can’t see that much difference. (Click on photos to view larger images. To close the larger image, click on the close button at the lower part of the pop-up screen). But then again, I’ve just been using the phone with the new firmware for a day. The after upgrade photos were taken with less daylight streaming into the office as I finished upgrading in the evening. I’ve read forum posts that claimed that R1CA021 comes with lower video quality.
The only problems I encountered with upgrading were:
1.) Busy Server. I encountered a busy server notice twice as the maximum number of connections to the Sony Ericsson update server was reached. This means a lot of people were upgrading their phones.
2.) Missing memory stick drive letter. After I upgraded, I connected my phone back to my PC and could no longer find the Sony Ericsson removable drive in my listing of drives connected to my computer. This missing USB drive problem is easily solved and I’ve previously written about how to fix it.
Below are the details of the new firmware as listed in Esato, an excellent website if you’re a Sony Ericsson fan boy like me:
– Increased Camera software version. Photo and Video quality, however, do not appear to have changed noticably.
– FIX: The Animated menu items bug for Themes is mostly resolved. After applying a theme with an animated menu, we still need to go to the Settings or Calls menu to start the animation, but it will not disappear again after this.
