I was in Epsylon3's 0722 and, as I was missing A2DP support, I flashed Quarx's 0723 yesterday by wiping just cache and dalvik cache. All was fine then (except for the laggy bootanimation, of course), but, this morning, without doing anything unusual or foulish (my Defy had just rested in a dock, like every other nights), some applications started to crash, mainly Play Store (that dreaded 'unfortunately, process android.media...' popup message) as soon as I tried to have some apps updated. I tried wiping Play Store's cache and data; rebooted into recovery and wiped cache and dalvik. Nothing helped! Then, I've restored a previous nand backup of Epsy's 0722.
Now, although still missing A2DP, I'm kinda afraid of flashing Quarx's 0724 (no direspect towards him intended, at all!).
Anyone here has experienced such weird issues in Quarx's 0723 build (still too early to ask the same about 0724)? Or, rather, one must wipe data too, whenever going from Epsy to Quarx (or the other way round)?
