Some apps for the E75 and other symbian phones may come unsigned. To aid you in signing those without having to wait for it to get signed online I have put together a small tutorial on how to do it yourselves.

Step1 Registration: Just follow this link to the OPDA forums http://www.opda.net.cn/index.php. Now look at the pictures to register if you have never registered on a forum before. For this you need basic English language skills.

Step 2 Get your .cer and .key: This step is the most important. You have to login at the apple for cer page of the forums using your previous created id and password. Get your IMEI and type into the IMEI fields, type the model of the phone and press submit. Your new .cer and .key will be available for download ASAP.

Step3 Hack: Get two apps from here: Signer(to sign apps on your desktop)&HelloOX 2.03(to hack your phone and not sign anymore).

After that sign HelloOx with the signer app and copy it on your memory card.

Launch HelloOx from there and wait for it to install. Launch the App and wait for it to do its thing, if while runnig  this it stops or takes too long just hit cancel& restart phone. Run it again(woked for me).

This will install ROMPatcher , run it and turn on all options.
