I can't make it work :(
I've downloaded the file, and installed it on my PC.
I followed the steps written above and deleted the vendor.xml file.
I plug-in my BB and and double click the Loader.exe file, a dialog box pop up with list of applications i want to restored and i checked the important applications i need. Then it started the process of loading the new OS i think because my phone was in white screen for awhile and rebooted too. when it turned ON again, i checked the version of my OS if it's already new but it still indicated my old version which is V188.8.131.521.
I've tried it 3 times already, but still the same.
What could have been wrong? Am i missing something that i supposed to do? Help please... :(
already found the workaround.
i just deleted all the files/folder of the old OS version on my PC as well as the new version i have downloaded awhile ago, then downloaded again this new version and followed all the steps again and now it's installed on my phone.
i will just observe for any difference with the old version, i'll update this post after few days.
