Hello. I was on system 2 running the Chinese version of the rom. I tried upgrading to multilanguage without any wipe, just using manual update from system updates. Something went wrong and I don't see when somebody calls me, it just appears as missed calls. I entered recovery and booted to system 1. Everything works fine with the same settings i had on system 2. My question is: what happens to system 2 now? Does it remain broken or it will, delete itself after some time and automatically make a copy of system 1? How do I flash multilanguage miui on system 2 without wiping entirely the SD card? Can this be done?
