Team Win Recovery Project 3.0.3-0



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.


A message to those with other variants of the G5:
The H850 International variant is the only one with an official bootloader unlock from LG.
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.

DOWNLOAD

You can find the device page here:
https://twrp.me/devices/lgg5h850.html

FULL STEPS FOR OBTAINING ROOT
  1. Follow LG's bootloader unlocking instructions here before you begin!
    Transparent.gif
  2. Download the latest TWRP .img for your device from this thread or twrp.me.
    Transparent.gif
  3. Use the same fastboot tool you downloaded in the LG unlock instructions to flash TWRP using the command:
    Code:
    fastboot flash recovery twrp-x.x.x-x-h850.img
    * Replace x.x.x-x with the actual version you are flashing!
    Transparent.gif
  4. Now you can either power off your phone and boot into recovery using the button combo [Volume Down] + [Power], or you can run this command in fastboot:
    Code:
    fastboot boot twrp-x.x.x-x-h850.img
  5. At this point, you will see the TWRP splash and reach a screen asking you if you want to allow system modifications.
    By swiping right, you will trigger dm-verity, and if you don't follow step 8 you will be unable to boot!
    If you are going to root your device or follow the rest of these steps, then it is safe to swipe right and enable modifications.

  6. Only if you want internal storage or data to work in TWRP:
    Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
    WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
    Go to [Reboot] -> [Recovery].
    Transparent.gif
  7. Please consider backing up your stock boot partition in TWRP before proceeding to the next steps!
    Transparent.gif
  8. If you want to be rooted with SuperSU:
    Download the latest SuperSU stable by Chainfire.
    Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
    -or-
    If you only want a bootable system partition or writable data in TWRP:
    Download dm-verity and force encryption disabler.
    Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.
    Transparent.gif
  9. Go to [Reboot] -> [System].
    Transparent.gif
  10. Wait 2-5 minutes for your device to finish setting itself up.
* MTP, known as Media Transfer Protocol, is the same way you transfer files from your PC to your device when booted into system.

Is the Sprint variant H850? I don't think so. You need to have an unlocked bootloader which has currently only become available this morning for the H850 European variant.

Thanks for this! Time to go buy my G5 now (Australia's a bit behind the times, only became available yesterday lol)

Following instructions found here

For TWRP to "stick" you must first boot directly into TWRP and not back into Android, until after flashing the SuperSU zip.
After flashing TWRP unplug the USB cable and pull the battery. Plug battery back in then boot into recovery which should hopefully load TWRP.
To boot into recovery:
a. Using 2 hands.. use one hand/finger to press/hold volume down.. and use the other hand for the power button. Press n hold both buttons.
b. As soon as you see the LG logo on the screen.. let go of the power button then quickly press it again (never letting go of volume down).
c. Keep holding until you see the Factory Reset screen. Click thru the factory reset screens.. Yes.. Yes...

10. You will not be able to decrypt your internal data while in TWRP but you can manually mount your external SD card to view the SuperSu zip. Feel free to back up first.. but otherwise.. time to install SuperSu. Click the Install button and navigate to the external_sd, select the SuperSu zip then swipe to install. Now you're rooted and TWRP'd! Reboot into system...

Stuck on TWRP splash screen.

I followed those instructions aswell but everything worked fine for me. Was able to get into twrp and flash supersu. Wonder why it's only working for some.

I wonder what is which has stopped everyone else's from working?:confused:
what was your process in flashing it and everything?

Just followed the instructions here to the letter. Didn't do anything different. Only thing I can think of is that I let the phone boot fully after unlocking and then installed twrp after that. Not even sure if that can affect anthing

Recovery hangs at TWRP splash screen.
My PC sees Recovery ADB device connected (in Device Manager), but ADB program doesn't see any device, so I can't get logs.

If that was the reason behind it working, i cant imagine there is away to do that once the device is unlocked and how long did it take to get into TWRP

    TWRP image for Nougat

    Hi everyone,
    Since the current TWRP image won't boot on Nougat firmware which (at time of writing) is v20a, I repacked it with Nougat kernel.

    You can find it here, just flash via fastboot.

    EDIT: exFAT support is not included, if you need to use your external MicroSD card please make sure you're using one with FAT32 file system (or reformat it)

    :)

    **NEW TWRP UPDATE**

    twrp-3.1.0-0-h850.img
    https://dl.twrp.me/h850/twrp-3.1.0-0-h850.img

    twrp-3.1.0-0-h830.img
    https://dl.twrp.me/h830/twrp-3.1.0-0-h830.img

    Flash it in TWRP (install zip) or use the official TWRP App to flash this boot.img.

    I'm currently looking into the date and time issue so hopefully I'll have a fix soon.

    Here is the system image from h850 for TWRP, hope it helps.
