[Recovery][H830] Team Win Recovery Project for the LG G5

[jcadduono]

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://xdaforums.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...

Team Win Recovery Project is a custom recovery for Android devices.
It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, and root your device.

I'll be able to test at about 7PM tonight.

 

[ledvedder]

I'm interested in assisting.

 

[mallman]

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.

 

[joemossjr]

tried it get unknown command

 

[spanky34]

tried it get unknown command

Same

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.

 

[jcadduono]

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?)

[KOLIOSIS]

does fastboot flash:recovery twrp.img work?

Or:
fastboot flash recovery recovery.img

 

[spanky34]

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.

 

[wolfgart]

mhhh, very strange, it seems a "custom unlocked" bootloader like Meizu products....

I hope to be wrong

 

[Killua96]

But the command to unlock bootloader hasn't changed? In the 6P its "fastboot flashing unlock"

[paperWastage]

No visible recovery partition available

Take a look at this post, and see where would recovery be hiding (actually hiding, or new name)

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:

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.

 

[wolfgart]

this is a custom bootloader by LG ...

Nothing real unlocked here....
