How to root and flash a custom rom

Hi all,

I'm really interested in buying this phone and flashing a custom ROM on it. It's great to see that this community of developers came together to make this a reality!

Unfortunately, I'm a little confused as to the exact steps we need to follow to flash a custom ROM. Say I want to flash this ROM here. What exactly do I need to do? I found this link here, but it sounds like that one outlines steps to just simply root. Does that guide already include TWRP, because that's the method that was outlined in the ROM link that I was interested in. Also does the guide I linked work for ANY android version?

Thanks in advance!
[G4 Q&A, Help & Troubleshooting] Xceeder:
A quick guide is -

Unlock bootloader

Download custom rom

Download twrp

Flash twrp

Reboot into twrp

Wipe system/data/dalvik/cache

Install custom rom

Reboot

Done...

Obviously there's more steps than that but it will give you a quick look into the setup and install process :)

Thanks for the reply! I think I understand everything after "Reboot into twrp". There is an option in recovery mode to flash zips, right? And that is different from the other methods that are using the .img file, I believe? Also, where is the root step in your process?

About the "Unlock bootloader" step, from what I've found, it sounds like this only works for the H815 model, but I also notice some people posting from their unlocked AT&T variant. How does that work?
[G4 Q&A, Help & Troubleshooting] Xceeder:
Yes in twrp recovery you can flash custom roms which come in zip files and some of the roms for the g4 are pre rooted but if not you can just flash superSU in recovery which is also a zip file and about the models of phones i believe the only ones that can be officially unlocked are the h815 international versions but I'd check xda for the full list just to be sure....

[G4 Q&A, Help & Troubleshooting] tdk0117:
Ah, I think I get it. The strange part is that to install TWRP, you need to be rooted first? So how can I install TWRP before flashing a custom ROM on a stock phone?
[G4 Q&A, Help & Troubleshooting] Xceeder:
No to install twrp you just have to unlock your bootloader using some adb commands and via the LG developers website and then you flash superSU via twrp , it might be different on other phones but for the LG G4 that's the way to do it...

Also the way i did mine was this-

Downloaded the rooted 10c image and used the lg unlock flash tool to wipe my device and install the pre rooted version 10c stock rom however so there's quite a few ways of rooting you could even just unlock your bootloader flash a custom rom but flash a pre rooted kernel , if you do that way then just look through the kernels on xda and just check which one preroots....

[G4 Q&A, Help & Troubleshooting] tdk0117:
Oooh I see. I think I keep getting mixed up between root and custom ROMs. If I'm understanding everything correctly, to be "rooted', just need to first install TWRP and then flash ANY rooted ROM e.g. stock versions, Genisys, Imperium, etc. The whole "unlocked bootloader" only really matters if you're in Marshmallow, right?
[G4 Q&A, Help & Troubleshooting] Xceeder:
Lol no i unlocked the bootloader on my old nexus 7 tabket and that was when it was on jelly bean haha it doesn't matter which version of android it is , if you want to make serious changes to the software then you have to unlock the bootloader , you're getting there buddy haha..
[G4 Q&A, Help & Troubleshooting] tdk0117:
Right! I did that for my nexus 7 too, but I think for the LG G4, you can only root on Lollipop, and you can't unlock the bootloader on Marshmallow except for the H815? There are all these threads lying around and I'm trying to pick up stuff from each one of them haha.

But for sure, your advice has been helpful! Thanks for all the replies!

Does the official LG backup application backup user apps data and settings?

(if I factory reset my phone will it restore my downloaded apps *data and settings* ?)
[G4 Q&A, Help & Troubleshooting] larsdennert:
Not sure but if you enabled the Google backup, it does a good job backing up everything from wifi settings to apps. Game settings/progress have to be sync'd with Google Play. Usually a game will have an internal setting for that that you elect or decline individually.

Yeah I know about Google stuff, but what about things like, say, tapatalk and it's settings/accounts/passwords?

Or my (non Google) navigation app with favorites, pois, saved routes and stuff? I could go on.

That's why I ask about a dedicated backup app, and in the case I am a good boy (as LG sees it, aka non rooted) LG should provide me with a way to fully backup my device. It is already a miss that LG backup does not allow for scheduled backups (earlier versions did). Does it at least backup everything?

If they do not provide such essential services, what's their excuse for discouraging/punishing people for unlocking/rooting the device?

Hello! I will come with a more stupid question.

I have dropped my phone in water. It survived, I took it out in time, took the battery out and put it in rice. I was still scarred and don't ask me how, I put the phone next to my ear and started hearing a strange fuzzy sound from top half of the phone(from behind), where I think the cpu is or something. I have listened to other phones, like a Samsung Galaxy s4 but those have not similar sound. Could it be water left inside the phone or yours makes the same strange sound?

I've had this lg g4 for about two hours now and i have been unable to get my outlook email account to sync. previously on my lg g3 it was as simple as just logging in and it would sync however now on my lg g4 it wont even allow me to add the email account. starting from a factory reset i go into the email application and select Microsoft exchange. from their i attempt to log into my account. then it tells me its checking auto info then after a couple seconds it says in a pop up. setup incomplete. cannot connect to server. check network connection and info, then try again. ( i have tried doing it on my data network and on my wifi both give the same result) then it brings me to the manual setup ( server address domain etc) ive googled and searched and tried different ports and server addresses to no avail and i am dumbfounded as to how i am supposed to sync my account to my phone. another perplexing thing it seems is that even the outlook app from Microsoft on the play store gives me the same behavior saying it cannot reach the server and using exchange services apk. gives the same behavior (gave me error code: status 110). the other odd thing is that i can make it sync just my outlook mail (using pop?) however not my calendar contacts etc. any ideas?

my g3 never exhibited any of this behavior.

Why isn't it possible to share slow motion video straight from the phone? Or is there something I'm missing?

Recently got the V10C update on my phone, and while it is lovely it has added a slow motion button to the camera app, what is the point of it if you can't share that footage straight from the phone to friends, YouTube etc?

I emailed LG a few weeks ago about this and their answer was "The G4 is a new product so we haven't yet addressed this issue. We hope to do so in a future software update" however no time frame was given for this update, and the problem also existed on the G3 which was released over a year ago.

What is the easiest way to share G4 slow mo video?

On the standard LG camera app flip it so the selfie camera is turned on, select the settings cog in the top left of the screen and there is an icon that looks like 2 faces. Clicking it makes the icon change so the faces are either pointing in opposite directions or the same way.

What does this do? I can't find the answer in the manual or anywhere on the net! :)

That sort of defeats the object of easily sharing video you've just shot with your friends. Not that I like Apple or the iPhone, but their slo-mo implementation is a million times better. The actualy quality of the video may be horrendous, but having normal speed then it slowing down is a great touch, and then just sharing as is to Facebook etc is much better than the implementation on any Android I've seen.

But, the way you've suggested also doesn't work. All a slo-mo vid on the G4 is, is a 120fps video played at 24fps speed making it appear like it is moving slowly. However you extract or share it it them remains a 120fps video played at 120fps speed so it looks like it is running normally. We need to be able to share those 120fps at 24fps to get slow motion video off our phones or share it to a PC, run through some video editing software, then share it which is a laborious task :(

G3 to G4: Is it worth it?

Hey guys,

Really deliberating whether or not it's worth the jump to the G4. I picked up my G3 brand new back in January so it's only been 8 months or so. The phone has been great, just wondering what people's thoughts are regarding whether it's worth the money to jump to the latest and greatest.

Hello everyone!

I've been planning on moving from the G2 to the G4, and I've some questions on using AOSP/Cyanogenmod/etc on it.

First, coming from the G2, using AOSP would mean having to settle for subpar camera quality because there is no access to LG's camera drivers. Is this also the case for the G4? Or is AOSP camera quality on par with a vanilla LG ROM?

Second, are there any other tradeoffs for using AOSP on the G4 other than LG-only apps and services?

That's all of my questions I guess. I'm excited to finally get a much better phone.

Hi,

I want to unlock my bootloader from my H815. But i often read that I cant install OTA-Updates with an unlocked bootloader anymore... Is it right? Atm my phone is running LP 5.1 V10d-EUR-XX with root rights. After unlocking I want to update to MM (via OTA) and install SuperSU for root rights and Xposed. Is it possible?

Thanks :)
[G4 Q&A, Help & Troubleshooting] BrotherZero:
My experience updating from LP to MM have been bad. Batterylife is the main issue, it's been terrible(and I did factory reset). Going from 4-5h SOT with the phone on for 40-50h, to 2-3h SOT and the phone on for 6-8h. The phone wont last a day anymore and I have to charge it twice. Another issue has been the knock on code. I used to love this feature when it was 3 knocks, but with MM it's minimum 6 knocks, making it useless as a fast way to unlock your phone.

But I have updated my MM today now to 20h(I had 20D) which supposedly should fix the battery issue. Otherwise I'm downgrading to LP.

i think the heat has increased for me. Can't tell any difference on the camera app but in general the experience has not been positive. Although it's very nice to have the latest security updates and the permission system for apps. It's mainly the battery life that's been bad for me, but maybe it will be fixed now.
