If you are using a tool like Eclipse+JCOP to develop and to deploy applets in the microSD cards of Cell-Idea, the used configuration will be the standard for testing purposes.
First, connect with your contactless terminal, and then reset, ...
/card -a a000000003000000 -c com.ibm.jc.CardManager
... select, ...
set-key 255/1/DES-ECB/404142434445464748494a4b4c4d4e4f 255/2/DES-ECB/404142434445464748494a4b4c4d4e4f 255/3/DES-ECB/404142434445464748494a4b4c4d4e4f
init-update 255
... and authenticate to Card Manager as usual, but when you are going to upload the package, use the command
upload -b 250 <cap_file_name>
The Eclipse+JCOP tool use "upload -d <cap_file_name>" as default, failing in the last block.
Finally, install the applet as usual:
install -i <instance_AID> -q C9#() <package_AID> <applet_AID>
