[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] JPT223:
Hey,

just updated to lineage-15.1-20180524-UNOFFICIAL-rolex.zip

I am having trouble with MTP.

Connection soon crashes. After this I can read DIRs but cannot fetch or delete files. Currently only internal SD is affected, Ext SD works fine, but could crash too?

Only phone reboot helps. Unplugging does not change anything.
