**************

Here's my "One Click" method to get TWRP onto the G4 H811.

**Special thanks to Team Codefire and vn_mobile for root.

PREREQUISITES:

Issues: This might take a few tries to run if the LG drivers don't fully install in download mode.
***If you still can't get it to work, uninstall all LG Drivers, reboot and install drivers from here: LG drivers


MANUAL MODE:
Step 1: Copy recovery.img to your internal storage.
Step 2: Pull battery, put back in. Press and hold Volume up and plug cable in. (Enter Download Mode)
Step 3: On your computer open up your Device Manager and look for:
**Ports (COM &LPT)
****LGE Mobile USB Serial Port (COM?)
Look for the port number in COM#! ?=#.
Example:LGE Mobile USB Serial Port (COM3). So mine is port 3.
Step 4: In your One-Click folder press Shift/Right-Click-Mouse and press "Open Command Window Here".
Step 5: Type Send_Command.exe \\.\COM? Make sure the ?=Port number from Step 2.
Example. Mine is Send_Command.exe \\.\COM3
Step 6: Type "id" without quotes and make sure this comes up: uid=0(root) gid=0(root) context=u:r:recovery:s0
Step 7: WARNING, IF YOU GET THIS PART WRONG OR DON'T USE H811 YOU CAN BRICK!
*****Type Flash command only for H811:

dd if=/data/media/0/recovery.img bs=8192 seek=35840 count=5120 of=/dev/block/mmcblk0

Step 8: Type: LEAVE
**Phone will reboot
DONE.....

Enter TWRP:Must be OEM Unlocked in Developer Options.
**In ADB: adb reboot recovert
or...
**Pull battery, put back in. Press and hold volume down/power. When LG Logo appears only let go power for a second and then press again till factory reset screen appears. Do factory reset to boot into TWRP. If you don't see TWRP run program again.

Very Nice. Are you using the same TWRP that is in the Original Development forum? Just curious to see if there are any changes such as time fix.

 

[mawells787]

Awesome sauce! First thing I'll do when I get my G4 tomorrow.

so, i'm a little confused.....do you have to use low effort root first or do you just put your phone in download mode then run this script.?then by installing super su you will gain root?sorry i am so computer illerate.i have followed the low effort root page since day 1, have rooted other phones but like i said ...just not up to speed transferring files,running commands etc. so i have held off trying to root myself even though i am pretty sure i understand the directions.just wondering if this way might be easier,thx in advance for any help in clarifying this for me.

No, you don't need low effort root. This is essentially the Nexus way. Just follow instructions and it will flash TWRp. Once you successfully reboot into TWRP. Download SuperSU.zip and flash it and you have root, it's very easy.

If you want TWRP to flash rom's then you want this!

But you can also use this to get root, by flashing the SuperSu.zip from TWRP. This is way easier than having to download a 5gb system.img, and manually running all the commands for root in the other root thread.

Thanks for that good explanation! Guess you posted just before I did!

I just hope no non-H811 person tries to flash this and bricks their device. I put a big warning on OP. But as always somebody always doesn't read OP.

Do you have H811 and did the md5 match and did you get to the end of the program that said to pull battery?

I had to run it twice on my phone and five times on my lady's phone, but after erasing data on both phones, trying to get into the recovery that wasn't installed, both are rooted and restored. Don't know why it went that way, but it doesn't much matter now that everything is well. Thanks again.

I think it was the drivers needing to load in download mode. Each time you ran it did it say to pull battery when it finished?
