Hello. You' re right I notice it too. I think you can try the app "Screen notifications" from the Play Store but I haven't tested it yet.

If I have done everything right, I have extracted the kdz file (T-mobile Croatia) and here we have recovery.img and boot.img attached to this post!

I post them because someone may be able to build CWM recovery for us, so I would like to make his life easier if he decides to do so.

Buddy you are my hero! Now I can get some stuff done with syncing CM12 sources to build CWM and after that hopefully TWRP with one buddy from BUG Forums. For now on, priority is CWM and hopefully CM12(.1 is optional). I tested out with extracting boot.img and recovery.img directly from phone and didn't had success with it (failed to do some stuff with creating .mk files for phone).

Also thanks to OP for .kdz file, it shall work on any other network because it is very much clean ROM (Croatian T-Mobile, only have few apps which can be uninstalled without root).

Peace from owner which had this phone rooted.

Nice! If you compile a working cwm for a start, YOU are a hero! Feel free to ask for anything else I can do to help you with (but I know only little stuff).

I just want to mention that the thanks for the .kdz file goes to the guys I mention at the credits!

Seems that bootloader is locked. Fastboot oem unlock didn't work and didn't have luck with loki or bump either.

You mean you wanted to flash recovery and the locked bootloader prevented you? If this is the case try the app "flashify" from Play Store.

If you just mention it, well, it's good to know. :good:

I flashed the recovery, that's not the problem, booting into it is.
Someone else with more experience about unlocking bootloaders (and time) could have a try.

I'll upload the CM device files to the github tomorrow.

Actually there isn't problem with booting in recovery you just need to do this button combination

Power + vol down and when lg logo apears press combination again

This is how LG G3 goes to recovery and it should work here too

Edit: I should upload also CM device files and kernel to my github next week at collège so we should have all files on one github

You can reboot to recovery with apps that offer an advanceed reboot menu, too. Like Link2sd.

Though, I don't know if @manakeri is talking about something else like: try boot to recovery but the locked bootloader prevents you..

    Will try to build working ROM this weekend. Spirit works as my primary internet connection so I need to swap sim every time I need to check so I did not have much time for test. I think I am very close to achieve at least booting build.

    I managed to boot lineage 14.1 on spirit. Only once from now, but I'TS SOMETHING.

    Fingers crossed, who knows, maybe someone will even CM for LG Spirit? :D

    Before CM let's first concentrate on bootloader ;) Also AOSP is just fine, yesterday tried MM (6.0) on friends Nexus 5 and I would say one thing: Doze rocks. he said that he forgot to charge phone at night (~35% battery left after all-day use with ~3h of SOT) and he woke up with 34% battery and only 1 mail notification. If bootloader stay locked (current state: downloading kdz v10h via phone connected to 4G), maybe I can build AOSP build of LP (5.1.1 maybe first?!?) for this phone and somehow figure out how to flash it on device.

    EDIT: AOSP LP is coming in next few weeks. I found solution how to flash it via stock recovery (which we can access via adb command written below and then pressing power button for few seconds) but then I need to sign and verify it (tried to flash SuperSU zip via adb sideload command and got errors like failed to verify whole-file signature and signature verification failed but I think that is SuperSU zip problem, not phone issue)

    Command which I used:

    Code:
    adb reboot recovery

    EDIT2: down is picture of stock recovery (looks crappy because I used SGM2 do make photo sorry folks)
