OTA installation failed on Motorola T720.
While downloading an application to the Motorola T720, an OTA failed
message comes up:"File corrupt". Does this mean the JAD/manifest
files are incorrect, class files are not correctly preverified...etc.?
In the event you experience problems, check the following:
1. Make sure ALL the fields in JAD file are EXACTLY IDENTICAL to
the fields in the manifest inside the JAR. And I mean *EXACTLY*. If
you have a white space after the Vendor name, for example, it wouldn't
work...
2. Make sure the size is ok
If it still doesn't work, try to upgrade the firmware. For firmware V8,
sometimes it has problem to download some MIDlets but these MIDlets
are installed fine on V11.
Phone issues a "file corrupt" error when installing program.
MIDlet operates fine in simulator but the phone issues a "file corrupt"
error when attempting to install the program
The PNG files in the MIDlet may contain meta-data, which the VM on
the phone cannot handle. This meta-data is attached to the PNG by
some graphic programs and is most often seen with images from digital
cameras. The image meta-data can include data like F-stop settings,
flash setting, resolution, and a host of other information.
To determine if image meta-data is the problem, try removing the PNG
images from the MIDlet and re-installing on the phone. If the error does
not appear, the PNG images will need replacing with versions that do
not contain meta-data.
