Team Win Recovery Project 3.0.2



WARNING: The stock boot image has dm-verity, which prevents you from booting if you swipe to enable system modifications!
SOLUTION: Flash a root such as SuperSU or phh-superuser. You can also flash no-verity-opt-encrypt.zip.


NOTICE: The LG G5 H830 currently has flashing locked!
You will need to use a tool to get around this limitation. At the moment, Team Win nor myself cannot provide anything for this.
The community, and user @tungkick has however provided an alternative method of flashing, which can be done via a full firmware flash using a TOT file.
See here for instructions: http://forum.xda-developers.com/tmobile-lg-g5/development/root-h830-t3384526


A message to those with other variants of the G5:
Should there be a time where your flashing mechanisms get cracked, simply mention my name on this thread or via private message and I would be happy to create a thread with TWRP for your device.
I have device trees ready for ALL variants of the G5, pending their unlock!

WHAT IS TWRP?

Oh come on, you know what it is - don't try to fool me!
In case you're serious, though...

i may be able to do it in a few hours as well but until then, I wanted to ask, is it not possible to fastboot boot <img> without flashing it? Only asking because that's what i've been doing lately with my huawei watch for testing without overwriting my recovery.

tried it get unknown command

Same
Code:
fastboot flash recovery twrp-3.0.1-0-h830.img
target reported max download size of 536870912 bytes
sending 'recovery' (19560 KB)...
OKAY [  0.488s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time: 0.516s

I wonder if we need to put the phone into download mode for it to take the flash... Not sure how to get there. The old hold volume up and insert usb cable trick from the G4 isn't working for me.

Awesome, anyone else? Looks like they really did lock it.
fastboot flash returns unknown command
fastboot boot returns unknown command

It seems that attempting to send an unsigned boot image returns in unknown command. I'm assuming that's just a generic error code returned by qualcomm secure flash due to invalid signature, rather than the command actually being unknown. (maybe fastboot does not have "invalid signature" return codes?)

fastboot flash recovery twrp.img didn't work. Fails with the unknown command error.

fastboot flash:recovery twrp.img doesn't work because it doesn't like the syntax.

But the command to unlock bootloader hasn't changed? In the 6P its "fastboot flashing unlock"
https://source.android.com/security/verifiedboot/verified-boot.html

I was already unlocked and tried to run that command earlier and it didn't work at all, as in, didn't like the syntax at all. I updated my fastboot and ran it just now on my already unlocked device:
Code:
fastboot flashing unlock
...
(bootloader)    Device already : unlocked!
OKAY [  0.020s]
finished. total time: 0.021s

Locking / unlocking with the newer fastboot won't yield any different results will it?

Still it's strange that both commands work, in 6P the other one doesn't work givingi the unknown command error.

    Thread re opened...

    I just want to make one thing clear

    Flaming/Trolling a Senior Recognized Developer who has done so much for this community is NOT how you go about getting more development accomplished.

    Please everyone, be kind to each other....respect those who have done much for this community, its very simple. Furthermore, you never know who the next great developer is going to be, so all users/developers/hackers should be treated with respect.

    This thread is now on our radar, please do not give us another reason to come in here and clean.

    Thanks,

    Baja

    Good news I was able to put twrp into the tot and it installed 100% once it rebooted it reinstalled the factory recovery.
    So there's still some tinkering to be done but making progress.

    Unless jcase somehow got it directly from LG, it's attainable somehow. I wonder if we could get him to share an unmodified aboot and let us work out the rest? Maybe a hint or two on writing to recovery while he's here ;)

    I got no files from anywhere, didn't need them for root. I will be in miami beach for a few days, I can dump recovery and boot from a device if someone wants to bring one up there today or on the 9th.

    Yes man,

    I'm the same that always has worked for all LG community.

    And you are the same that on G4 irc channel last year pm'ed me to have G4 unlock.bin file.....

    Shame of you man

    An unlock bin that anyone with the ohone could have given me. A worthless file at that.. You then proceeded to continue to garass me for years, to the point i sold my flex.

    You harass devs until they stop, then you insult inspiring developers.
