    I'm impressed, does it have theme option and how is the display?

    You changed file system to f2fs from ext4, any difference?

    Thanks again.

    Hi @niTe_RiDeR_Pro ,

    I have a few questions:

    1. These commands, should be run in fastboot or normal mode......cd c:\adb
    adb pull -p /sdcard c:\bacon_full_backup?

    Am not able to access the backup on OPO > Internal storage, only can access the backup created on usb-otg?

    2. On COS 13.1.2, only Data and Cache be changed to f2fs, not System.

    3. I'm glad that created the initial backup both on usb-otg and Internal storage.

    Hoping to hear from you,

    Thanks.



    Edit:

    Care to clarify step 13 and 14?

    Lastly does, changing, Data and Cache to f2fs make a noticeable change or mere a placebo effect?

    Not spotted a theme option but I'm not familiar with themes. I don't see a noticeable improvement on switching to f2fs, maybe browsing through my photos is quicker. I found the switch to f2fs quite complicated as I had the permissions problem which took a while to resolve.

    Thanks, I agree, not a noticeable difference, more of a pain.

    Hi, @remedy , Lineage OS for OPO IMO, is probably the best N ROM for OPO. Apart from themes all look fine. None bugs that I noticed till now, Display is as good as COS, can consider it after COS as a daily driver...Your thoughts?

    Thanks.

    Today I went to Settings > About phone > LineageOS updates and I was offered the 6 Jan unofficial update!

    Also, I went into TWRP recovery then Advanced > Terminal. In this terminal window it is possible to apply trim to the f2fs partitions using the commands "fstrim -v /data" and also "fstrim -v /cache". This does not work for the /system which is ext4. I had previously used this terminal to issue the commands to sort out the permissions problem rather than using ADB.

    The LineageOS rom seems trouble free; this is very encouraging. If I needed to do a clean install I would probably use mini GApps rather than nano as mini replaces some of the CM apps with their Google equivalents which I prefer.

    Hi,

    I found the same...

    Downloaded the 368 MB update on PC and flashed zip using usb-otg. Perfect.

    Go to updates, set to manual.

    Great stable ROM.

    Am using Micro gapps.

    Thanks.


    Edit;

    All my OPOs partitions are ext4 now.

    Extremely stable, no WiFi network issues. Smooth as silk.

    Trying to get the feel of N.

    Thanks.

    I believe that OOS does support f2fs on /data and /cache. I've been using f2fs for a month with no issues.

    Ok. Sorry for late reply. I was having my exams.
    Saw your screenshot. Seems like something went wrong and your system & cache aren't formatted to f2fs. Its good that you didnt, because COS 13 probably doesn't support /system as f2fs.

    1) Those commands are to be run in windows cmd (run as administrator) (copy paste it as it is)

    2) You have to copy back your internal storage from your PC. See step 11 for doing so.

    3) If you have your internal storage in USB OTG too then thats good. You can copy back the files either by using File Manager in TWRP or by booting into COS and then copying it using some file manager.

    Step 13 & 14: Go to the home screen of TWRP (the screen where you see buttons like Install, Wipe, Backup etc), tap on settings and tick the option "use rm -rf instead of formatting". Why because when TWRP restores a backup, it re-formats the partition into its original file system i.e. ext4. Using this option will prevent reformatting.

    Hello @niTe_RiDeR_Pro, which practical use has f2fs instead of ext4? I don't talk about benchmark scores, do you have any examples in which (life) situation it's more useful or faster? I will definately change the cache to f2fs because it's the easiest one haha
