G4 Root (Testing)

[macdaddie87]

This is a test root method for the G4. It is based off of the original root method for rooting LG devices. The original method showed modified in the boot loader but it didn't have su. This a modified script to push su correctly and the su used by the H815.

Note: On the H815 If you would like root all you have to do is unlock boot loader, flash twrp for G4 then flash the supersu.zip

WARNING: USE AT YOUR OWN RISK!!

I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this ROM
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.

This is a new method that i discovered. Instead of rooting we are just going to flash TWRP then we can root through the recovery. I have tested this on my G3 and i can confirm that you are able to flash recoveries through download mode.

The Recovery used in this is TWRP for H815 and I am not sure of how compatible it is with other variants but if it gives you root then its worth testing.

Files:LGG4_rFLASH.zip
Drivers:HERE


Step 1: Enable USB Debugging

Step 2: Download G4 Flasher and unzip, Also Install Drivers

Step 3: In unzipped folder open a new command prompt window (Shift+Right click)

Step 4: Run this command

adb.exe push recovery.img /data/local/tmp/

Step 5: Enter Download Mode (Hold Volume Up While plugging in Usb Cable)

Step 6: Check Device Manager> Serial Port (Windows) and make sure your Phones COM is set to 41, if not then change it. After changing it you may have to unplug usb, pull battery and then reboot into download mode.

Step 7: Open a new Command prompt window just like before. in the folder you extracted.

Step 8: Run this Command

Send_Command.exe \\.\COM41

.

Step 9: Run this to Backup your current recovery

dd if=/dev/block/platform/f9824900.sdhci/by-name/recovery of=/data/local/tmp/recoverybak.img

Step 10: It will now show a # then run this

dd if=/dev/zero of=/dev/block/platform/f9824900.sdhci/by-name/recovery

Step 11: Then run this

dd if=/data/local/tmp/recovery.img of=/dev/block/platform/f9824900.sdhci/by-name/recovery

Step 12: Pull battery and try to boot into recovery

Step 13: Flash Supersu.zip

Note:: to restore original Recovery all you have to do is pull it
adb pull /data/local/tmp/recoverybak.img \

Rename it recovery.img (you might have to delete or rename the one that was extracted from the zip earlier because the can only be one recovery.img in a folder )
then rinse and repeat all the steps

Edit - Just tried to download the root zip, and I got a message that it's infected with a virus.

Does anyone tried this method on the T-Mobile G4 H811?

I was able to use a web-based ZIP extractor to extract then compress it. I have done no scanning for viruses, I simply extracted and repackaged the files.

I think I am unlock is only for unlocking the boot loader not rooting

So I tried this on the H811 (T-Mobile) version.
Everything worked just as described UNTIL the part where I needed to run the root script.
After I paste the SH command, it thinks for a moment, and returns me to the # line...
Not sure how to continue from here, but will be happy to be a guinea pig if someone can tell me what to try.

Same result . Nothing happens ?

this is my input : sh /data/local/tmp/root_g4.sh/data/local/tmp/UPDATE-SuperSU-v2.46.zip /data/local/tmp/busybox

it stays on # nothing more?!
