Some Things I've Learned About Flashing

(Click here to view the original thread with full colors/images)

Posted by: ctfb

With all the posting going on about using Crack2d to unlock the eeprom I just had to give it a try. I have a GU87 with AT&T Wireless. I had previously flashed from A38 to A39_nosound without any significant changes to the phone except the removal of the camera sound and some minor language changes as the US English language pack was overwritten.

This time I wanted to do it all so I downgraded to A22, ran Crack2d, and flashed to A53_nosound. Now there are more changes than when I went from A38 to A39. It seems that having the EEPROM unlocked makes a big difference when flashing.

With the A38 -> A39 upgrade the startup animations, pictures and shutdown image all stayed AT&T, now with the EEPROM unlocked everything went to the Panasonic animation and screens. Also the WAP icon was originally named "Browser" and now is named "Vodafone live!".

The font is bold when entering text & numbers in A53 as reported in another post. The shortcut icon for the camera on the bottom right of the screen was a small arrow and now is a picture of a camera. The camera & messages icons have switched places. Finally, there is a kb counter on the top left of the browser window when surfing.

Also with the EEPROM unlocked I was able to upload the WallBreaker .ctc file and switch from internal games to infusio. Yea, a new game to play, although it is in italian, but who needs instructions for WallBreaker anyway

Oh, and I learned that flipping the switch from UK English to US English under Mobile Variant in CB2000 is a bad thing. It actually removes English as a selectible option and defaults the phone to Dutch. Other languages are still available and flipping the switch back restores UK English, whew!

One other possibly bad thing for CB2000 v1.35c and A53 is that the "@" or "m>"shortcut key doesn't seem to be recognized in the mobile variant section and presents a error that the setting was unreadable. The down side is that the press & hold to start the browser immediatley doesn't work anymore. The single tap to go to the browser menu and then select "start browser" does work. Hopefully there will be a newer version of CB2000 that addresses this.

So, to sum things up, flashing with a EEPROM locked phone will keep the carrier specific options in place and just upgrage the firmware with minor changes. Flashing with the EEPROM unlocked will reset the phone to the default OS (Panasonic) options - startup & shutdown screens, icon names, etc.

Now, to find a way to rename that Vodafone live! icon back to Browser

Got more! Feed the phone and watch it grow

do not use the cb2000, use the mobile configurator instead!

I downloaded the SCOPE Apps. I'm just waiting for my reg info.
Thank you for building those apps!

I never knew there was a long press for the @ button. Is it possible to get the long press back if seems to be gone? Anyone know?

Lost_Rebel's Mobile Phone Configurator has the options to change this. When I get my reg. info I'll post with the results.

It also allows to set the border color, which is quite buggy in CB2000.

Nice program

BB88 & I have been "hacking" the camera sound in this post:

Lost_Rebel, I can hex edit a file or two but I don't know how to progam, do you think it would be possible to add functionality to your configuratior or another app that would modify the firmware on the phone instead of editing it on the PC and then waiting for 15 minutes during a flash to see what happens?

The first idea would be to upload Hex code replacement that would overwrite the cam sound with blank data as the specific hex offsets can be easily identified for each firmware version. That way people could safely turn that sound on & off at will without risking a flash.

Possible?
