Xperia C5 Ultra Dual-Roll back to previous firmware - Sony Xperia C5 Ultra

I own a Sony Xperia C5 Ultra dual recently updated to Marsmallow 6.0. As for the time being there is no "one click root" tool for 6.0 firmware, can I -with assist of the proper tools (flashtool 0.9.19.2 and E5533_29.1.B.0.101_RU.ftf rom)- safely downgrade or roll back to firmware 5.1, where my C5 operates better and there is support of kingroot. Thanks in advance

Can C5 Ultra Marshmallow still be rooted ??

Since C5 ultra Dual ( E5533) just got fresh update 6.0 , more update for other C5s will be rolling in few hours I guess .
So will this update be able to get flashed by flashtool on unlocked bootloader devices ? And how about recovery and most important rooting method will still be the same as it was on 5.1 ?
U got an 6.0 update?

Yes to the first one, second one no idea don't have a c5, third yes if bootloader is unlocked and no if it's locked, pretty sure there is no root method for 6.0 and kingroot doesn't work after 5.1

I'd really appreciate it if you'd send me a link for the download.
Thanks for your attention.

Does the Xperia Z5C use the same ROMs as the full-size Z5?

My Xperia Z5 Compact has been barely usable since the OTA upgrade to 7.1.1, so I'm looking into burning a custom ROM. There's a Lineage ROM for the regular-sized Xperia Z5. Would the instructions and ROM also work for the Z5 Compact?

No, there are some differences between the devices. I would advise doing a clean install of 7.1.1 or downgrading to 7.0. Doing one of these will fix your issues. Also, there is a thread for Lineage on our Z5C here.
Good luck :fingers-crossed:
