Had some trouble on my Z2 and thought I'd create an account here and ask for your advice before I did something stupid. Have no experience with rooting or modding whatsoever, so bear with me please.
I bought a Z2 whose screen never slept. I found out that the responsible was com.sonyericsson.startupflagservice v2, who would always run when I turned the phone on and remained on my notification area with no text, just an icon resembling two blue screens superposed. If I force stopped the process, the phone would sleep normally until I powered it off. When I turned it on, the process would be there again preventing sleep.
I did some research and learned how to flash a different ROM, wipe cache, wipe dalvik... Did all that and the process would still be there. Rooted my phone, bought Titanium Backup and froze the process... it worked fine, but would I reset to factory settings, there was the process again.
And finally I come to my question: would un-installing the process and wiping its data with Titanium backup work? Would I be at risk of bricking my phone?
I'm running out of options on what to do and returning isn't really an option!
Thank you very much!
