Marshmallow Upgrade, From Stable To Weekly

Feb 9, 2016
Hi everyone,
first of all sorry for my english, i hope you could understand me. I have a MI4 (only by a month) with MIUI (stable) and i would like to try the new marshmallow. To flashing the ROM i need TWRP but my doubt is...I need to have a backup of my files before flash or the upgrade is "silent" like the upgrade by OTA? I hope I was clear

thanks for the answer

No you cannot go directly. You need to merge the partitions first with 5.12.17 from this forum. Have a look at other posts for mi4 the topic is well covered.
