Can this be flashed through twrp on unlocked bootloader h815? Currently running s3v3n's custom rom
[G4 Android Development] Underworled:
NO

[MENTION=4747579]HK_Jason_L[/MENTION] Can we do full wipe ( system,data,cache,dalvik ) ? i know you only did cache, but your friend did full wipe ?¿
[G4 Android Development] HK_Jason_L:
no need unlocked bootloader ;)
[G4 Android Development] HK_Jason_L:
My friend did
[G4 Android Development] takeoff342:
So underworled u can try it with full reset and Report. U can either do a dirty Flash like Jason and then if flashed do a reset....

try and Report [MENTION=5301294]Jason[/MENTION] as soon i downloaded it, i upload it to a mirror
[G4 Android Development] Underworled:
Downloading..

Anyone did ?

I will do full wipe..

He said his friend did full wipe and all ok

[G4 Android Development] Underworled:
You will do dirty flash ?

EDIT : Rom downloaded, i'm bite confusing..i dont know if u should flash or not
[G4 Android Development] HK_Jason_L:
Yes.... thats why I felt confuse that should I post it out :(

I may need someone to test it
[G4 Android Development] Underworled:
MMmm, Can you make a video doing the instalation again ?

One friend is doing atm,

I 'm reporting
[G4 Android Development] takeoff342:
in fact we have 2 devices with this art to Flash and both are fine. so 100% success.

you must not feel confuse Jason. I reported the V20A KDZ in a german Forum as it came out yesterday and everybody runs out and Flash.......with no success. But....was it my mistake? NO i think. everybody must know Flash it or not. You only share you knowing with us. It is ok Jason :D [MENTION=5439922]Underworled[/MENTION] He surly dont make a Video for you and Flash it again for it. I am sure they both have there personally Things installed and no fun to Flash again. But its Jasons choice of course
[G4 Android Development] Underworled:
I did not order the video just for me , but for all the people who are not sure if the process works or not
[G4 Android Development] HK_Jason_L:

Did You lose root?
[G4 Android Development] Underworled:
LOOK , downgrading with flashtool may cause brick

If you want back to 5.1 without issue do following:

You need a TWRP Backup of 5.1 and 10D Bootloader and 10D Modem Files

1. Go to TWRP

2. Restore Backup

3. flash Modem of 10D

4. Bootloader of 10D

5. reboot and enjoy

yes,lose
[G4 Android Development] takeoff342:
I Think via Flash tool you dont come back to 5.1
[G4 Android Development] HK_Jason_L:
so thats mean there is noway to roll back :crying:

hopefully it work well:angel:
[G4 Android Development] Underworled:
With ''LGFLASHTOOL 2014' atm no.

I think you mustn't do friend.

I think 99 % you will get brick doing that
[G4 Android Development] dbamaro:
if i got root... can i flash LP with flashfire... in this case I would be in M already... but woth root!

[MENTION=5439922]Underworled[/MENTION]
[G4 Android Development] HK_Jason_L:
alright, for safe you should wait the update of flashtool atm

btw I tried to roll back but it show an error to me and no brick :)
[G4 Android Development] takeoff342:
The Problem is, if u are on a stock Marshmallow as yours Jason, how will you get the recommended files for a downgrade like the 5.1 TWRP, bootloader etc.....
[G4 Android Development] Underworled:
I think that will come in 2020 HAHA

Probably i will do ( flash with ff ) today
[G4 Android Development] HK_Jason_L:
oh sorry my English suck, I mean the 6.0 work well
[G4 Android Development] takeoff342:
No i am not on 6.0 u misunderstood. you are on 6.0 right? But for going back to 5.1 you Need a 5.1 bootloader and TWRP. So i ask that that is a Problem to get that on a stock 6.0 Device.
[G4 Android Development] Underworled:
Yeah, thats true, atm you cant go 6.0 > 5.1 with flashtool

You will flash 6.0 with flashfire -?
[G4 Android Development] Resync:
care to make FF package for LP 10D?
[G4 Android Development] takeoff342:
You Need root for this. but if u Flash This Rom you are on stock 6.0 and dont have root. that is the Problem.

I am more and more thinking about first to unlock my bootloader or simply sell my G4 and Change to another developer. Cause so the G4 makes no fun. AND we must remember. If we Flash THIS Rom from Jason....ok we have the V20A but what is with future updates? we dont get. And in the case that it never give the way to Flash with flashtool we ever stay on the V20A.

So in the Moment i dont Flash This rom
[G4 Android Development] Underworled:
MMM i dont think so, is an official rom without root, then you will get the updates by your imei..

And next update maybe will come in months...
[G4 Android Development] takeoff342:
yes.....but remember the G4 is out since Months. And until now there is no way to Flash custom roms (ok FF) or custom kernels (even not with FF). So in all the months the G4 is out, nothing is happend. No no the risk is to much that in the next months nothing happens too
[G4 Android Development] iNeri:
1.-This is stock rom, so is the same as if you flashed with LG flashtool.

2.-Becouse of above you recieve OTA updates directly from LG poland.

3.-When LG flash tool has an update you can flash your newer's .KDZ over this withot problem.

Correct me if i am wrong.
[G4 Android Development] takeoff342:
who garantee me that the Flash tool gets an update? guys......i have my decission. I dont Flash. What you would do....your choice

PS: here is another download Link for the Rom. Jason if you want put it in your opener post.

[G4 Android Development] Underworled:
2 - OTA updates depend of your imei.. not rom/kdz.. etc
[G4 Android Development] HK_Jason_L:
alright THX
[G4 Android Development] iNeri:
Good to know.

So, we only have to worry about if we can downgrade whitout problems right?
[G4 Android Development] Underworled:
How long did it take to install the rom ? About 15-20 min ??
[G4 Android Development] takeoff342:
Yes. When i flashed the seven roms it need so 10 to 15 mins
[G4 Android Development] HK_Jason_L:
In condition!

1st situation : Stock Rom 15-20 mins

2nd situation : custom rom like 7 hd or others, may be 1 mins(for me
[G4 Android Development] emprize:
When i click the flash icon in ff, it turn off immediately, when did i do wrong?

Full wipe but stil v10e in software info
[G4 Android Development] betovanbuuren:
I have one question:

Why knock code was removed?, you stated that will be back in a future update... but afaik we won't have root with this method once we are in MM due to our locked BL. So no FF once we flash this .zip with FF right?

So i think there won't be any update soon because of the lack of root for us (the people with locked BL in stock MM)

Am i right? or im missing something?
[G4 Android Development] takeoff342:
Exact what I said and why I not flash. For the ones who have flashed....how is the performance in scrolling and gaming? Difference to 5.1? Jason and the others? Thanks
[G4 Android Development] Underworled:
Everything moves much more fluid..

You have to test it... all is so good. And you can disable heads up notification ( whatsap... etc )
[G4 Android Development] betovanbuuren:
so [MENTION=5439922]Underworled[/MENTION] is correct that knock code was disabled?
[G4 Android Development] Underworled:
Yes.
[G4 Android Development] betovanbuuren:
[MENTION=4747579]HK_Jason_L[/MENTION] is there a way to enable knock code?
[G4 Android Development] HK_Jason_L:
no because it is cut by LG
[G4 Android Development] Underworled:
If u know anything about root, mention me plz :) thx
[G4 Android Development] HK_Jason_L:
I will, as I want root too :)
[G4 Android Development] takeoff342:
Who uses knock code...

But would be interesting why LG but it. Instead of put some news into mm it cut something. Watch if Samsung rolles out mm they ever put much good news into and slightly changes on UI. So maybe I sell my g4 and buy a s6 ☺
[G4 Android Development] Underworled:
Then u have to wait a bit more..to see 6.0 on S6..

I think u dont know how samsung is with updates.. haha:D GOOD LUCK with knox.

dorimanx said '' samsung is not for devs''
[G4 Android Development] emprize:
updated to android 6.0, and puzzle and dragon get force close...
[G4 Android Development] betovanbuuren:
ok so i will flash it, thanks [MENTION=4747579]HK_Jason_L[/MENTION] & [MENTION=5439922]Underworled[/MENTION] .. Clean flash, look forward to hear when root is available for us, i guess will be the same low effor root process when available.

About the software info being shown with v10e instead of H81520A is it normal?
[G4 Android Development] HK_Jason_L:
yes,same problem, game will fix in next patch(should be
[G4 Android Development] HK_Jason_L:
so it shown 10e may case by dirty flash, but clean flash may not happen
[G4 Android Development] takeoff342:
I had many Samsung with Knox. The first I removed after root. Of course Knox status was 0x1 but.....don't care me. For that on every galaxy is root without problems custom roms without end and flash fw by Odin without probs.

Puzzle and dragons is still not optimized for mm. You must wait for an update from the game
[G4 Android Development] emprize:
android 6.0 fix is live, suppose is v. 8.3.2, which is live version:crying:
[G4 Android Development] takeoff342:

[G4 Android Development] takeoff342:
and noticed any Speed improvments in Scrolling, gaming etc?
[G4 Android Development] vwadam:
so in ff need to choose Flash firmware package (or i need to use Flash ZIP or OTA? ) and in partitions choose boot,system,trustzone,dbi/sdi and modem firmware to?
[G4 Android Development] Jojo5678:
Yes my G4 was a bit laggy when closing apps and using yt and the lag is gone now.

It feels a bit snappier when typing but overall nothing really noticable. Don't know much about gaming since I never played any games.

I was hoping for a better battery life actually. Haven't noticed anything better yet, but we'll see. Better give it a few days and a few recharges to settle down.

I do like that the silent mode is available again.

You flash zip and add the wipe cache partition.

Guys, just to be sure, double tap to wake is here? I am asking because don't know what knock code is.

Root could be archived when unlocking bl of my h815 and flash the modified kernel? Right?

[G4 Android Development] Jojo5678:
Yes, double tap to wake works and you can stil pulldown from the top of your phone when screen is locked to see the time and notifications.

Knock code is when you tap on 4 parts of the screen to unlock your device. That's gone for now

Can't help you with the other question, though.
[G4 Android Development] HK_Jason_L:
tap to wake still here :)

yes, you can root in this way but for unlocked bootloader only

Your cust partition doesn`t match the cust for this rom. Try to flash the file attached, it`s the cust from 10e. If it doesn`t help, use Windows LG Firmware Extract to extract cust.img from the latest kdz which didn`t show you such kind of notification and replace cust.img in my zip with your cust.img, than flash it.

View attachment LGG4_cust-restore_H815_10e.zip

How to extract:

1. Unzip the downloaded windows LG firmware Extract.zip to some folder.

2. Copy the kdz file there.

3. Open the WindowsLGFirmwareExtract.exe.

4. Click Open > select the kdz file.

5. Check the .dz file in the list

5. Click Extract KDZ.

6. Once extracted, open the rezulting .dz file

5. Check cust files in the other list.

6. Click Extract DZ.

7. Rename the biggest extracted cust_XXXXX.bin file to cust. img

8. Replace the file in my zip with the cust.img you have just created (I use Total Commander for this).

Is this actually a problem though? Besides the message on boot up, I don't see anything wrong with the day to day function of the phone.

Just wondering can you use FlashFire add the rom, add Flash latest SuperSU BETA-SuperSU-v2.52, and Root_Kernel_Android_6.0_Marshmallow_by_S3V3N.zip then hit flash? This would give folks with out an unlocked bootloader 6.0 with root?
[G4 Android Development] jonny_blagwind:
sorry for sounding like a total noob but where are we getting flashfire from? is it an app or a programme for your pc? also people say you don't need root in the thread but at the top it says you need root to use flash fire?
[G4 Android Development] wadken1:
To get FlashFire you need to join Chainfire's Beta programe - just search for his thread on xda - there's a link their which takes you to a sign-up page on PlayStore.

You do need root to run Flashfire - that's easy enough to do. I used the "Low Effort" method from this forum.

Cheers
[G4 Android Development] jonny_blagwind:
Thanks i'm just working on that now i've extracted the .tar file and but its showing as only 433mb? the zip file is 1.4gb and the tutorial vid says it should be nearly 5gb extracted should i try downloading it again?

---------- Post added at 02:22 PM ---------- Previous post was at 02:20 PM ----------

also i'm on 10d atm the low effort method has a file for 10c should this still work?
[G4 Android Development] wadken1:
Firstly, I remember correctly you need also to extract the zip - it will then inflate to 5Gb or so all in one file called system.img (I think).

Second. I wouldn't try to install a 10C image if you already have 10D installed. I'm not an expert on this but I read a lot about people getting into trouble when trying to revert to earlier versions. May not be an issue at all but for safety I would say to either :-

a) go back to 10C by flashing the appropriate stock KDZ for your phone and then using the pre-rooted system image approach

OR

b) use the alternative "root injection" method which involves pulling you existing system image from your phone, injecting root (using LInux) and then putting it back on the phone.

I have only done the second part of a) above so you will need to read up the details from the appropriate threads.

Cheers
[G4 Android Development] jonny_blagwind:
That's what it's extracted to but only 433mb

Sadly (luckily by the sounds) despite the port bat file detecting my com as no 8 it does not connect I'll give the root injection a look in though!
[G4 Android Development] Medizinmann:
No, you need unlocked bootloader to achieve root with MM.

Yes, you need root to use flashfire and get from Chainfires beta test program over his Google+ site.

But with flashing this rom you then loose root and most probably the ability to use an unofficial bootloader unlock - if ever available...

I would not do it and wait for an unofficial bootloader unlock - then flash a rooted version through TWRP.

And BTW : As I read it MM for the LG G4 is still buggy - I would wait a while.

[G4 Android Development] roopesh:
Umm... I followed the instructions... after flashing, my G4 H815 (SEA) is in a bootloop. It comes up with

Secure booting Error
Error Code : 1014

Any advice?
[G4 Android Development] jonny_blagwind:
Enter recovery and reset?
[G4 Android Development] roopesh:
I tried getting into recovery, it never enters. Assuming this is correct:

1. Powered down

2. Hold down Power + Volume Down

3. See Logo

4. Release for 1 second

5. Hold down Power + Volume Down

It just bootloops me back to the secure booting error.
[G4 Android Development] jonny_blagwind:
Release just the power button for 1 second

https://youtu.be/mCxJ5k8vWEI
[G4 Android Development] roopesh:
OK, got into recovery, but still in the bootloop.

I can get to downloader mode, but when I try LGFlashTool with the original KDZ, the process gets stuck at extraction.

EDIT: OK, got it back to SEA through the LGFlashTool. Helpful tip: Don't run LGFlashTool and have the KDZs on a networked drive. Once I moved everything to my [virtual] C: drive, everything restored fine.

I guess that means you can downgrade from this 6.0 back to 5.1?
