I got random restart with sMIUI 5.9.27 too.
I finally fixed it with following steps.
1. Make a sMIUI 5.9.27 ROM (uncheck all MODs.)
2. Install TWRP
3. Wipe cache and install new ROM via TWRP
Hi seb1991,
I flashed 5.9.24 on MI2S , it ramdon restart more the 10 times in an hour.
So I flahsed back 5.9.17. Everythine looks fine now.
Any big change between versions?
I merged partitions. Then install sMiui 5.5.22.
But I found there is no GAPPS(google play, gmail ... etc) !!
And CWM alaways overwite by offical Recovery.
Is that normal ?
