    Thanks for your answer!

    I'm downloading oos-3.6.0-oneplus2-fastboot-20170824.zip hope this will work...

    ADB works? I mean it says flash is OK when I've tried to flash twrp.. Tried booting.. then I get device status null..
    I've googled the output and the only hit I've got was one from XDA and that one was a bad one.. apparently a hardware defect..

    I hope I can get it up and running!

    Would you have a magic toolbox like this for the 3T? I only have recovery available and adb sideload..

    That's more than enough to revive the device...
    You can just sideload the ROM zip from oneplus.net/downloads or copy the ROM to your internal storage and apply update via stock recovery...

    There's a unbrick tool for both devices, the 3 and 3t, just Google "oneplus 3t unbrick tool xda" and it should be in the very first search results

    @Sam Nakamura and @bucika66, I've been struggling with a OP2 and I have a very similar issue.

    I can get TWRP on it and install a Lineage OS rom (tried 4-5 version and then moved on to other roms) I got into a boot animation loop.

    I can get the phone back to fastboot and need to use the unbricking tool to go back to OOS 3.0.2 which I can then upgrade to 3.6.1.

    I'm not sure why I can't install any other rom on the device besides TWRP and OOS. The TWRP log for installing a rom like LOS said it was 100% successful but when the phone boots it gets stuck in the animation loop. I can't figure out why it won't boot to the OS.

    I saw an issue a page ago regarding the camera preventing LOS from booting but not sure if that's the case or if there is something else preventing it. Since it's a new LOS build I am not sure how to get the LOS failed boot log.

    Did you clean flash lineageOS? Meaning wiping everything except internal storage before flashing lineageOS, GApps, magisk...

    If so try formatting each partition (system, cache, data), this will wipe everything from your storage, so you'll need to copy the relevant files onto your phone again...

    Taking logs while bootloop isn't the easiest thing, you'll need working ADB for this (adb shell cat/proc/kmesg or dmesg), please Google yourself as I can't remember 100%, might be incorrect...

    let me know about the results!

    Did you try to flash anything else than lineageOS, please try aosp extended (AEX) or resurrection remix (RR) too, just to be sure that it's not lineageOS borking your phone..

    I did wipe everything and then formatted the partition.

    I was having the issue with ADB at that time because when I flash a new version of an OS ADB is generally disabled

    Woot, I fixed it.

    Based on the past couple of pages, I tried to find a persist.img and flash it which worked.

    That's super weird because I've never run into this issue on a phone so far.

    Hello, for method A2001 only method 1 works?
    After finishing the procedure, the green text comes out but the phone remains locked on the 1+ logo and the writing powered by andoird, does not start in recovery even by pressing the keys.
    It is recognized in fastboot mode, but it is not possible to flash because the bootloader is locked.
    I also tried the modified version of the tool with english recovery, but nothing to do ...
    Can you help me? Thanks

    Hello Naman,
    Trying to unbrick the Oneplus2, when I run MSM Download Tool and press "Start" it starts, but does nothing... I can only press "Stop", big button with something written in chinese language or just close the program.
    Any ideas? Could you please help me? :)

    /proc/last_kmesg has been removed. /sys/fs/pstore is used now
