Quick update on my issue.

Well Sprint was no help with getting my replacement. Even thou I have the total equipment protection and Sprint Customer service sent me to my local Sprint store to get a replacement, the local store wouldn't help. The local store says that they are not a corporate owned store, even though they are listed as one in the Sprint database, and could not help.

My only option was to drive to NEW JERSEY!!! That's 6 hours away! (I'm in Vermont)

So...I called Amazon, where I purchased the phone. New phone is on it's way, old phone is being returned, no questions asked. Should have it by Monday.

Thanks for all the help everyone. (Don't think I'll be trying to put on a custom bootloader next time, and dropping the total protection plan)

Don't know for sure but my guess is it'll work on every rooted lollipop version.

Hi [MENTION=3708520]blkdimnd[/MENTION],

I'm sorry to hear about this and for the delay in my response. It's a "Holiday Week" here in the Philippines (being mostly a Catholic country, we observe Holy Week).

About three (3) other members have experienced the same as you did. One of them (username is [MENTION=5159277]danmak89[/MENTION]) was somehow able to pinpoint the cause and was about to try some other methods. You may be interested to read his posts, starting at Page 22 of this thread, or send him a PM.

The last method that he was about to try was this: http://xdaforums.com/showthread.php?t=2582142. But before you do anything, please send him a message. I hope I wasn't too late in responding.

I might not respond or post for the rest of the week due to the Holy Week. I will try whenever I can.

Improved One-click Approach

Hi Friends,

There's a new thread that gives root + TWRP on the LG G3!

http://xdaforums.com/lg-g3/general/d855-one-click-root-twrp-recovery-t3072767#post59897602

Based on the first post, it is targeted to the LG G3 D855, but I think it's possible to for users to repackage it by replacing the following image files with that of their LG G3 model/variant:

1. boot.img and recovery.img (I assume that users will need to "bump" these beforehand)

2. laf.img

3. aboot.img (not sure if this requires the Kitkat version)

Take a look at the thread and see if it works for you!

One-click Script Modified for Other LG G3 models/variants

Hi Friends,

I have done testing on my LG G3 D858HK and the one-click script modified by @jac10000 worked!

I likewise made some modifications:

1. Push @Skin1980's "Sharpening Mod Script" to the device.

2. Disabled the "LEAVE" command from Download Mode so that users will just do a battery pull to manually exit Download Mode

3. Users will reboot the device manually to Recovery Mode and then run the "Sharpening Mod Script" (tap "Install" and then look for it in /data/local/tmp directory)

Hi @cowboysgz,

How did you root your LG G3? Via the one-click script, I assume?

To add TWRP, you have to accomplish a few things. Please visit the First Post of this thread. There is a link for you to download. It's a script that @avicohh created to automate the rooting process, and then eventually modified by @jac10000 to add TWRP (specific to the LG G3 D855). Then I modified it further to try making it compatible for other LG G3 models/variants.

Hi [MENTION=5133359]dornz[/MENTION],

Imageprep is a little different now, no longer the same as it was back in version 1.4. I invite you to try it out (you may need to reflash first - make sure to backup beforehand) if you want to try it, and let me know what you think if you are going to try it.

A one click root&recovery for D855 models!
[G3 General] topet2k12001:
Yup, that's the one I was referring to in my response earlier. :) The one I have is based off that, only modified a bit to cater also to other LG G3 models (D855 and others too).

Plus some added extras form my version:

1. If you put your Kitkat Firmware (KDZ file) in the folder, part of the script is to extract the files you need via the KDZ and TOT Extractor Tool

2. It will also "bump" your custom recovery (if not yet done)

3. It will push a zip-flashable file, the Sharpening Mod Script by [MENTION=2174433]Skin1980[/MENTION] (this flashable zip is executed from custom recovery - at the later part of the script you already have it installed in your device). What this does is it will also "bump" your kernel (boot.img) and will allow you to set your preferred display sharpness level (some users don't like the default sharpness of the LG G3 as it creates a "ghosting effect" when reading text)
[G3 General] cowboysgz:
I was having trouble with all the extracting lol but luckily I have the D855 model lol Just one quick question. I used the one click root and recovery, can I only use bump'd roms or any rom as long as it's for my D855?

Please Help! Phone will not boot anymore :(

Hey guys!

Please help me.

I executed version 1.5 (the latest). I was running lolipop 5.0.1 on D852.

Downloaded KitKat, extracted the files, and then my device rebooted and I saw the upgrading firmware do not unplug USB cable. And then the script told me:

"Please use CTRL-C and then Y" to exit.

So I hit CTRL-C and Y.

And then rebooted the phone. And it will not reboot anymore! :(

It is just a black screen and after a while, I see some text that sais : "boot certification verify" and it dissapears and the LED flasheds BLUE and RED.

Nothing is working and I have no money to buy another cell :(

Help anyone?
[G3 General] topet2k12001:
Hi [MENTION=6574754]D852_Canada[/MENTION],

I'm not sure if you missed it, but at the end of the script there's a reminder that tells you to reboot into Recovery Mode (meaning you should not boot directly into Android yet) because there is one final step that needs to be done. :)

As of now, you need to pull the battery out first to turn it off. Wait for a few seconds, and put the battery back on.

Now, reboot to Recovery Mode (press/hold the power and volume down button...when you see the LG "Life's Good" animation, release for a second and then press/hold power and volume down button again...you will see a white screen with "Factory Reset" written. Choose "Yes" twice - don't worry, data won't be deleted).

Once in Recovery Mode (TWRP), tap on Install. You'll be taken to a File Manager. Tap on "Up One Level" and open "data"->"local->"tmp". You're supposed to see Sharpening Mod 3.5.zip. Select that file and flash it.

Once this is done, you can boot to Android normally.

You'll be fine...based on what you wrote, it looks like the script worked as it should (you just forgot that one last step).

Hi,

I am having a similar problem. I have a rooted D852 on stock Lollipop.

I used the prepacked imageprep.zip for D852 and followed the procedure. When I rebooted I also got the flashing red and blue LED lights.

Pulled battery and follwed the procedure to get into recovery. Once there I navigated to data"->"local->"tmp but I don't see the sharpening mod zip file. I see UPDATE-SuperSU-v2.46.zip!

I tried flashing it and rebooting, but I am back to the alternating flashing lights.

The prepackaged imapeprep.zip had version 1.4 of the script

Help please.
[G3 General] topet2k12001:
Hi @D852_Canada,

Congrats, and glad to know it worked out for you! :) Thanks for trying it out. :)

Hm, I couldn't think of anything that would cause that...all scripts do is to automate multiple commands in one or a few clicks (or one or a few commands to be entered). My only theory is that either you are on a custom ROM prior to following the guide, or possibly an older Kitkat firmware (these are just theories).

If you are interested to test further, I would suggest a clean reflash of the device so that any external variables are eliminated. And then try it again and let's see how it goes. Only if you are interested, of course (and make sure to back up prior).

Hi @rezadue,

May I know the Post # of this thread that you followed? From what you wrote, I get the impression that there is a slight mix-up of steps that were followed. :)

If you want to do it the same way that @D852_Canada did, please use only the download and the steps at the First Post (First Page) of this thread. Do not use anything else (I just kept/maintained the old methods for reference purposes).

If you still want to follow the old method, it's okay so long as you don't mix the steps with the latest one that is found on the First Post (First Page) of this thread.

I tried to use post 153. but unfortunately I forgot the step about installing busybox and opening it.

[G3 General] D852_Canada:
[MENTION=5231281]topet2k12001[/MENTION]: Nah, no custom ROM. Stock LG G3 Androit 5.0.1

My hunch is that it is the Over-sharpening fix doing something funny since it is the only thing that patches the kernel on boot.

If I want to remove the over-sharpening patch only (and keep the ROOT and TWRP) in order to test without it, how do I proceed?

Thank you sir.
[G3 General] topet2k12001:
Hi [MENTION=6574754]D852_Canada[/MENTION],

Yes the oversharpening fix does include the patching of the Kernel (boot.img)...but it is a required step for adding TWRP to the LG G3 running on Lollipop. A stock, non-patched kernel is the reason why you experienced the flashing blue and red and not being able to boot to Android.

If you will revert the kernel (boot.img) to stock, that means you will have to let go of TWRP as well (you'll also need to revert to stock recovery.img).

Let me modify the script with just patching the kernel and then please test it and let me know. If the rebooting (or not booting) issue is still there then we will need to look at another possible cause.

I do remember though that even in previous versions of the script, some D852 owners are experiencing that (you can do a search in this thread). I am using a D858Hk and used the same script and did not experience a random non-boot issue.
[G3 General] rezadue:
Since I can't get into download mode the flash the stock KDZ, but can get to TWRP, can I just put a ROM ( such as CM12) on the external SD card, mount it in TWRP and flash it to recover from this?
[G3 General] topet2k12001:
Hi [MENTION=2472758]ingoljosh[/MENTION],

The logic behind this has been explained in previous posts as well as the first page (under Click to show content). We're not flashing the entire Kitkat KDZ firmware here...we're just extracting a couple of files from it.
[G3 General] rezadue:
Thanks. I downloaded the zip file and since I could not get the computer to recognize my phone, I put it on the external SD card.

Booted into recovery and flashed the zip file and used TWRP to reboot.

Now when I start the phone I don't get the flashing lights. I see the main LG boot screen followed by a small LG logo and the caption security error.

the phone shus down after that.

Youre help is appreciated.
[G3 General] topet2k12001:
Hi [MENTION=4134502]rezadue[/MENTION],

I can give manual steps but to be honest, using version 1.5 would have been easier for you. :) You will just need your Kitkat Firmware handy. The instructions are in the script itself and they will appear at the appropriate time. Would you like to try it?

After all, the script is merely an automated way of achieving what I am supposed to tell you in more laborious steps.
[G3 General] rezadue:
Thanks for the quick replies. I am confused. Don't version 1.4 and 1.5 of the script do basically the same thing?

I will try whatever will get me back to a working phone.

At the moment I can boot into TWRP.

I can't boot into download mode.

Phone is not recognized when I plug it in with the volume up held.

Phone won't boot into Android. It goes past the start screen followed by LG Security error and then the screen goes off.

Please point me in the direction of what I should try and I will.

Thanks again.
[G3 General] D852_Canada:
[MENTION=5231281]topet2k12001[/MENTION]:

The only reason why the oversharpening fixes the issues is because it auto-bumps the kernel in memory as well and it allows it to boot with no further security checks.

Couldn't just flashing a bumped kernel from 5.0.1 (boot.img) accomplish the same thing without the oversharpening fix?

At least this is what I understand so far.

If you offer in your script the option to install either a bumped kernel or the oversharpening script that patches and autobumps the kernel that would be the best. That way if the user decides NOT to install the oversharpening fix, you can upload to the device the bumped boot.img from the lollipop version on the device (same method as extracting the aboot.bin, etc.) and it will still boot with no issues and you would have TWRP as well.

---------- Post added at 01:50 AM ---------- Previous post was at 01:44 AM ----------

[MENTION=4134502]rezadue[/MENTION]:

The simplest thing where you are at the moment is to simply copy the "Sharpening-Mod-3.5.zip" to your SD Card and install that via TWRP.

That should fix all your issues as it autobumps the kernel thus bypassing security checks and as a bonus it fixes your sharpening issues and make your G3 usable! :)

Simple as that.

bootloader

Hi i am not sure if i am at the correct thread.

I have LG G3 D855 rooted on stock lollipop. I tried to install TWRP but after the restart i am getting a secure boot error and after just blinking the light. I remove the battery and the phone starts normally. So that means that the bootloader is locked right? Is there any way to do unlock it or i have to go first to KITKAT unlock it and after back again to lollipop? Thank you in advance.
[G3 General] D852_Canada:
[MENTION=4134502]rezadue[/MENTION]:

Wait you are doing this on a G3 right? D852? Running the default 5.0.1 ROM?

Did you try unplugging the battery and rebooting? (do not forget to remove USB wire as well!)

Or else you can always try to flash the stock boot from 5.0.1 (did you make a backup? if not download the kdz and extract/rename "boot.img" and install to boot partition with TWRP) and remove the battery and power on.

This should make you boot at least but will not make TWRP work.

If not, you might need to 0 wipe your boot partition before copying boot.img from stock ROM.

I am guessing that your boot partition is dirty and that somehow the oversharpening script is unable to find the proper bytes sequence to patch. This is what would be happening and why the device is unable to boot.

Once the device boots, run version 1.5 and follow steps.

[G3 General] topet2k12001:
Hi D852_Canada,

Yes, we are practically saying the same thing. :) In my version 1.4, what you are requesting for is what the script actucally does, minus the "rooting" part (version 1.4 assumes you are already rooted prior).

The Oversharpening Mod Script is actually two (2) scripts: the sharpening fix, and then bump. If you wish to not apply/modify the sharpening level (i.e. keep LG G3's "Default" sharpening value), you may simply select value 40. In this manner, only the bump portion will be the one at work. In this sense, users have the option to only bump and not apply the sharpening fix. Hence, your feature request (option to bump only) is already in place. Or are you requesting that the script should "bump" the boot.img (Kernel) even prior to the user rebooting? If so, that can be done as well.

As far as uploading a "bump'd" boot.img (as well as a Kitkat aboot.img and laf.img) pre-packaged to the script, yes that is possible and in fact has been accomplished (as an example, [MENTION=4479135]jac10000[/MENTION] modified the automated rooting script of [MENTION=2200907]avicohh[/MENTION] in this manner, for the D855). What I have in mind though is to have like a one-stop-shop for various LG G3 models/variants, hence my modification is done in this manner that you see currently.

I'm working on some more improvements to make the experience more seamless for everyone, so please stay tuned.

Hi [MENTION=5443932]giorgosperi[/MENTION],

1. Indeed, you will get a secure boot error. Flashing TWRP on Lollipop is no longer as it was back during Kitkat.

2. Flashing blue/red (with secure boot error) when booting to custom recovery (TWRP) means that (1) your custom recovery (TWRP) is not yet "bump'd" (or "patched"), and/or (2) you haven't replaced your aboot.img and laf.img partitions with Kitkat versions yet.

3. If you do replace aboot.img and laf.img with Kitkat versions, and if you flashed a "bump'd" TWRP, you will be able to boot to custom recovery but not

Hi [MENTION=4134502]rezadue[/MENTION],

Just follow the full tutorial from the start. Select only one method (version 1.4 or 1.5). At this point, due to the mix-up in the steps followed, the time spent in back-and-forth conversation will take longer than to simply start from step 1. Definitely I can help you with providing instructions manually, but the script should address this faster than having to guide you step by step.

1. Version 1.4 assumes that you have your phone already rooted and running Lollipop. It involves manually extracting some Kitkat files from your Kitkat firmware and copying them over to certain folders.

2. Version 1.5 assumes that you haven't rooted yet and running Lollipop. It will also involve some extraction but in a (comparatively) simpler manner. Just make sure that at the end of the script, DO NOT REBOOT TO ANDROID. Reboot to custom recovery first and follow the instructions written in the script.

Hi [MENTION=6511877]ravi.vydianathan[/MENTION],

Great to hear that. Congrats!
