1. D855 2GB/16GB

2. Imageprep on latest official Lollipop.

3. Sorry, what do you mean by that?

4. Well, I did everything like it's described in post #153, so all image files from (I guess latest) European Kitkat (10L).

Hi [MENTION=2741808]fxandrei[/MENTION],

Congrats! Please mention:

1. LG G3 model/variant

2. Which method did you use (Imageprep, Manual Kitkat Downgrade, Manual No Downgrade)?

3. Did "Download Mode" work?

4. Did you have to flash all the Kitkat image files for "Download Mode" to work, or just the aboot.img and laf.img?

---------- Post added at 02:17 AM ---------- Previous post was at 01:54 AM ----------

@topet2k12001, will the simple recovery switcher work after the "imageprep" procedure? If yes, then can you please advise which file to use for the stock recovery image - is it the lollipop recovery.img inside the liimagefiles folder? Would that mean one can do an ota update? Also after that if we want to switch back to custom recovery, will just selecting the twrp image file work? Apologies for so many queries. Hope to hear from you.

Try to flash the zip with new recovery from your current recovery.

If you have only the img then flash it with flashify from playstore.

[G3 General] topet2k12001:
Hi @ravi.vydianathan,

Sorry I haven't heard of the "Simple Recovery Switcher" yet. I did Google it. Am I correct to understand that it's an app that allows you to "switch" (flash) between a custom recovery and the stock recovery?

To answer your question, merely switching back to stock recovery still won't allow you to update via OTA. Rooting the LG G3 is responsible for you not being able to update to OTA...not the presence of a custom recovery. So I do not know what benefit you will get from switching back to a stock recovery.

Hi [MENTION=4692977]nickslg[/MENTION],

The error message means that it can't find the file named imageprep1.4.sh.

Check: is the package saved in the right location?

Please send us screenshots of your File Manager; show the contents of your Internal Storage. We should see a folder named "imageprep".

And then please open "imageprep" folder and show us the contents as well.

Imageprep should have been extracted to the Internal Storage (/sdcard) and not the External SD Card storage (/external_sd) where you put a MicroSD card.

Please help!

Hi guys,

I'm new here and need your help desperately... I have LG G3 D855 Europe rooted with stock Lollipop 5.0 (V20h).

Cand someone help me with pre packed files of KK for my version?

After I have these files I just copy them into that folder and then run the script? Is that all?

I really like this topic and I want my G3 with custom recovery.....with your help!

Thanks a lot!
[G3 General] topet2k12001:
Hi @nickslg,

Thanks for the pictures. Not sure how you extracted Imageprep, but it appears that you have created (intentional or otherwise) a sub-folder named "imageprep1.4" and then that's where you extracted the files. What should have been done is to do a simple extract of the Imageprep zip file, because I already organized it (sub-folders, files, etc.) in a particular manner.

There are two solutions:

1. Go inside the "imageprep1.4" folder, copy all the contents, go outside the "imageprep1.4" folder (you'll be in "imageprep" folder) and paste all the files there. Then run the command.

or...

2. In Terminal, type su (to root) and then Enter. Once running as root, type "sh /sdcard/imageprep/imageprep1.4/imageprep1.4.sh" (without the quotes). This way, we are commanding Terminal to look inside imageprep1.4 folder (which is inside "imageprep" folder) where the actual script "imageprep1.4.sh" is located, and execute it.

[G3 General] topet2k12001:
Hi [MENTION=4692977]nickslg[/MENTION],

At this point I would suggest reading the tutorial very carefully and really read through it, and then following it to the letter. I put that "checking process" in the script to ensure that not only do users have the correct image files in the correct location, but also that these image files are renamed properly. The instructions are carefully laid out in Post #153, plus there is a video tutorial that you can download and follow. Best of luck!
[G3 General] nickslg:
Ok thanks its been a long day ill try again tomorrow thanks for your help
[G3 General] topet2k12001:
Hi [MENTION=4692977]nickslg[/MENTION],

No problem. I looked at your screenshots from your previous post and it appears that you have renamed the files properly. At this point (and following the cause of your previous error), please review the location of the Kitkat Image Files. Make sure that they are inside "kkimagefiles" sub-foler. And that the "kkimagefiles" sub-folder is placed inside "imageprep". I was actually wondering why you created a sub-folder named "imageprep1.4" and placed all the files in there.

The folder structure should look like this:

/sdcard/imageprep/kkimagefiles (and then the Kitkat Image Files are inside of it)

"/sdcard" in this sense pertains to your Internal Storage.

I need to sleep now, I have work later. I also suggest reading back to previous posts; I remember one of the users posted screenshots to illustrate how your Imageprep folders/sub-folders should look like.

Do not worry; yours is simply a case of Imageprep Script not finding the files because they are not in the correct locations. This should be easy to solve.

[MENTION=5231281]topet2k12001[/MENTION], you can find the simple recovery switcher here: http://xdaforums.com/android/apps-games/app-simple-recovery-switcher-t2857554. It's by [MENTION=3537886]graffixnyc[/MENTION]. Seems it can switch recoveries i.e. Custom to stock and back and gives you the ability to do an OTA update and you also don't lose root. I have the tool but haven't tried it yet. That's why I wanted your opinion. Thanks.

[G3 General] afilbit:
Greetings everyone. So I have a LG G3 D855 for about a week ago and I updated it as soon as I got home to the V20h-EUR-XX (lollipop). I live in Portugal so I have the European one.

I already rooted my phone but I wanted to install xposed framework. I searched a lot and I'm pretty sure this is the safest way to flash TWRP. I never needed to extract KDZ files before so I searched more and I found the pre-packed imageprep. Do I download the LG G3 D855 SEAXX or the LG G3 D855?

I don't really want to brick this phone because I don't have a lot of money to buy a new one so can anyone help me to have this flashed in the safest way?
[G3 General] topet2k12001:
HI [MENTION=4489126]afilbit[/MENTION],

Welcome!

Please visit Post #153 of this thread. It already has the instructions laid out in detail. There is also a link to a video tutorial which you can download (note that in the video I am using an LG G3 D858HK).

If I remember correctly, someone who has the same model/variant as yours did upload a pre-packed Imageprep. Just read back some pages and most likely you'll find it. Or just wait for someone to respond.

Hi folks

Here my contribution: a imageprep ready to put in the Internal Storage, based on Brazil D855P VIVO ROM.

It´s not tested in an another network operator, it´s a Vivo Brazil only...

Run it at your own risk.

Executed in adb shell like the AWESOME Video tutorial and run flawlessly

Guys, can anyone help me wyth my pb? I instaled topet's script but something gone wrong on my d855, because as for now, I can't boot to the system anymore. Red and blue light is flashing and the message oabout certificates appears.

At last, I can reach _only_ TWRP but completly don't know how to fix my issue now.

What I exactly did: I ran the script, type "yes" and then 0 as en sharpening option. After that I typed Yes once again to replace all bootstack. then rebooted and stuck.

Files got from the one of teh topic on this forum (prepacked for 855).

Any idea what to do?

And one more - if I install CM12 my bootloader will be replaced by CM12 one or not?

I already have my ADB backup, but I don't know if it will replace existing bootloader partition, or not.

Fastboot not availabe dl mode too.

Any help apprectiated, TIA

[G3 General] ravi.vydianathan:
[MENTION=6396211]komornick[/MENTION] you may like to consult the troubleshooting section (Q&A) section. There is one which sounds like yours.
[G3 General] komornick:
thanks for the quick answer, fortunately I resolved my PB just a seconds before, by executing topet's script once again into the TWRP "Terminal command" and it seems that it solved the issue for now - and for now, I checked that the TWRP and system - both works fine, I am not sure if fastboot and downlowad mode works too, but hope yes ;)

by the way - It's a little bit strange for me, because during second execution of the script. There was no possibility to answer any questions - script just ran "by itself" and executed all commands. Into the sharpening, I couldn't chose any too and seen a number of rows with information that chosen option is not valid, but at last, no more certificate errors :)

I am writing this information there in case if someone had the same problem.

[MENTION=891586]topet[/MENTION]: am I right that if I ran this script second time, it will overwrite my backuped lollipop files by KK files under lollipop name?

best regards,

Hmm....

Apparently one has to click "Download Now" then manually remove the virus.

Clicking "Download" tries to install some stupid irrelevant EZ downloader. Man, I hate those websites that try to sneak crap onto your system and has multiple buttons with purposely no way of telling which does what :mad:
[G3 General] komornick:
[MENTION=4386025]Adso3000[/MENTION], please be careful using this prepack, because I used those files to bump mine d855 EUR and got some troubles after this operation. I am not claiming that those files are improper or somehting like that, it could be my fault probably...

A big thank you from Denmark. Wife's from Cebu btw, so it's cool to see other great things coming out of the Philippines :D

I've been itching to do this having flashed so many previous devices on a regular basis for years. Now I can wave goodbye to the frustration of reading G+ community posts about great ROMs I could never try myself.

:victory:

1. D855 32GB V20h-EUR-XX Android 5.0 (European).

2. Imageprep (No Downgrade).

3. "Download Mode" worked.

4. I did NOT replace entire boot stack. I put all files from below link into the imageprep folders as directed.

https://drive.google.com/folder/d/0B_7RX232M2_ObjB0Nk1WdmZLYTQ/edit (courtesy of Phil Dorney). It comes with TWRP 2.8.5.0

HI @rodharden,

Thanks for your contribution! I'll add that to Post #153.

Hi @komornick,

Let me try to absorb what you wrote by reading it again. Sorry I'm tired as I just came home from a long day at work. Or would you mind re-writing what just happened, to the best of your memory?

Hi @isholay,

Great to know, congrats! Please try rebooting the phone into Download Mode too, just to be sure, and revert back.

Hi @Adso3000,

Congrats!

Oh I see...your wife is from the Philippines too. Cebu is the "middle" part/region of the Philippines (the "Visayas" region). It's where the famous Boracay Beach is. Have you visited the Philippines (or are you currently staying here)?

Hi @afilbit,

Ah...a brave soul. :) Please report back your findings. Back up your files first and prepare for a full reflash in the event of a soft brick!

I am actually interested to know if aboot.img and laf.img is the same regardless of LG G3 variant. Because if that is the case, I might as well come up with Imageprep 1.5 where it will already be pre-packed with aboot.img and laf.img....although, I do know that some LG G3 variants only work in Download Mode if their corresponding laf.img is flashed (laf.img is responsible for having Download Mode feature). This applies to the US Verizon model/variant...and US Sprint, I believe.

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

I noticed that you have been consistently sharing image files (Kitkat Boot Stack and Bump'd TWRP). Are you sharing only for the D855 Euro version? Or are you also sharing for other LG G3 variants?

I appreciate what you are doing. I'd like to make a suggestion: before uploading, put them all in a folder and name the folder with the appropriate LG G3 model/variant. This is to help ensure that nobody will end up downloading/flashing the incorrect image files (it can get confusing for people who like to download instead of extracting these image files on their own).

Keep up the good work!
[G3 General] komornick:
Hi, [MENTION=891586]topet[/MENTION]: i apologize for such chaotic description. I was in rush and a little panic, so let me explain all once again:

My g3 is d855 2/16 on stock 20h. I wanted to flash TWRP and after some fails on other methods i decided to try yours. So i got prepacked imageprep for 855 eur from this thread and followed step by step by your instruction: agree on instalation by typing yes, then no sharpening by typing 0 and at last yes for replacig whole bootstack (but without restarting to check if needed of no...). As i remember, during the execution of the script there was a short message that something wasn't find but you know i am not so quite sure now.. Sory for this.

After reboot i stuck on alert about certificates and the only thing i could do was to enter the twrp (!) recovery (i am not sure now but once or twice i seen a message to agree on reset to factory just after entering recovery and after agreed twice it moved me to TWRP instead reset settings... But some times ago i tried to install TWRP by other way and instruction tells that it happen like this...i do not know it was due to this old attempt or it was recovery from script instalation) anyway, my "panic miode" was set to highest level but i just remind that someone there had similar situation aborting sharpening script, so in TWRP i ran yours script once again.

And then, script just follow all actions (still in TWRP) but without asking me about anything (no confirmation to continue etc.), so i hadn't chace to chose sharpening mode too and after this point of script (mean sharpening settings) i just seen some messages of improper values. When the script just finished its work i rebooted and all works OK.

Hope this time it was a bit brighter described than before but if you need more information just let me know.

And now i want to thank you for your work and help.

I am sure that it was my mistake or bad luck :)

Can you boot the phone to TWRP custom recovery? From phone off, press and hold the power button and volume down. When you see the LG Logo showing "Life's Good", release for a second and then press and hold power and volume down again. Then choose "Yes" (it'll show up twice).

[G3 General] ravi.vydianathan:
[MENTION=4327605]squall458[/MENTION], just download the twrp image from their website, rename it to twrp.img, place it in the root of your internal sd card, through terminal emulator or adb shell type the following (one after another):

su

dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

After that reboot to recovery to check version. You should be done.

Flashing through flashify might also work but haven't tried it out.
