    Either flash a signed flashable zip via TWRP or fastboot flash the contents of a fastboot images zip.

    If you flash a signed flashable zip, you'll need to replace TWRP with stock recovery which you can extract from the corresponding fastboot zip.

    Mirrors of the zips are here...

    You managed to get LOS and TWRP installed so you obviously know how to flash a rom!

    Download the latest signed flashable zip from from the XDA thread I linked you to, boot into TWRP, wipe system, data & both caches and then flash the rom zip.

    I bought the OP5, I am planning on giving my hopefully updated OPO to my mother. (She's still using a Samsung Gravity 3) . Mom is anxious to get her "new" phone. The old Samsung Gravity3 barely captures a signal.

    I am running Windows 10.

    I got as far as the step 11c in TWRP Recovery to Wipe > Format Data. After the Wipe finished my OPO automatically rebooted.After this reboot, my desktop no longer recognizes my OPO. So I cannot proceed to the next step to copy OPO_Oxygenos_3.1.4_STOCK_05_FE82K17.ZIP into storage. I did back up what was there before I did the wipe.

    UPDATE: Even though Windows 10 File Manager doesn't see my O

    I train dogs for a living. I am new to doing Android stuff. Should I recover whatever got backed up so that my desktop can see the OPO? I await your sage advice.

    It's LOS attempt at humour with a late April fool.

    Wait for the next update and it'll be gone.

    The language is Pirate!

    Hello Habib,

    Thanks for your clear step-by-step guide how to install LineageOS!
    I have installed LineageOS 15.1-20180121-UNOFFICIAL-bacon.
    It took me 1 day but finally it works fine on my OPO.

    Well the upgrade to 15.1 went fairly smoothly except for a few issues.
    - The aptX package that worked on 14 doesn't seem to work on 15.1 so now I don't have aptX anymore.:mad:
    - I forgot to backup my SMS messages so now they're gone. :(

    Hi, was running LOS 14.1. Did a deep wipe clean using TWRP, wiping all except OTG. Now the 15.1 won't install mounting USB-OTG, and installing via TWRP, displaying failed... What am I doing wrong?

    Doing the same 14.1 would clean install fine? Should I reflash it over 14.1?

    Had to clean reflash 14.1 after wiping all, using usb-otg, and update to 15.1.

    Any ways to clean flash 15.1 via twrp using usb-otg, after wiping all?
