Hali!
Nekem ezzel a kóddal sikerült JAVA-t telepíteni a d900i-re:
1. Enter *# 52828378 #
2. Enter OTA Type Setting Menu
3. Switch from GPRS OTA to SERIAL OTA
4. Add software or games to Java Uploader (Uploader.exe)
5. Enter #*5737425#
6. Select PPP UP and USB (First time use only else just go straight to step 7)
7. Select SERIAL DOWNLOAD
8. Watch the download
9. Launch the software
10. Switch back from SERIAL OTA to GPRS OTA to get WAP working
WARNING:
DO NOT SELECT PPP UP SECOND TIME UPLOADING GO STRAIGHT TO SERIAL
WHEN YOUR IN SERIAL OTA MODE SELECT "NO" WHEN THE PHONE ASKS TO SEND HTTP INFO AS IT CAN CRASH AND RESTART THE PHONE
És a "Softick PPP+Java Uploader+szervízmenüben babrálós verziót" használom.
