Hi,
Same symptom:
"Extended Call Log not working after UNofficial PR1.2. flash. App starts loading and then crashes"

In x terminal i got this error:
"extcallog: error while loading shared libraries: librtcom-eventlogger.so.0: cannot open shared object file: No such file or directory"

I have search this file and i didn't found it, I found only librtcom-eventlogger.so.1 file. Maybe this version mismatch could be the problem.

Is there any solution to run this app on the new swversion ?
