Thank you for reply, if I face the same issue with long booting time, I'll PM you.
As for this issue - I experienced the same with original software from Ibasso as well. There fore I thought this might be hardware issue since two different softwares had the same effect.
It is normal on the first boot after flashing the new firmware only. Subsequent reboots may show this message, but not for so long. Anyway, it depends on number of additional apps installed.
I doubt it would help. If you have no many apps installed, I'd suggest to "Factory data reset" from Android's "Backup & reset". If the problem persists, please PM me.
No, it is not a hardware problem. I've heard a couple of similar reports with my previous firmware build, but related to "Voice style" setting. I've never experienced it myself, which makes it hard to fix. If you decide to go for a factory reset, please note if it corrects this problem as well. If it won't, again: please PM me for instructions on how to collect more info for investigation.
