Hi,
I recently bought a G3 and 3 days ago i downgraded to kitkat to be able to root, I also installed CM12, it was fine until I had bootloops so I reinstalled it and yesterday my device had a kernel crash.
I wanted to go back to stock G3 but couldn't reach download mode! Even after a kernel crash and selecting "launch download mode" it crashes.
I don't know what to do, do you have an idea?
Thanks!

Pull battery, put it back in, boot into recovery, choose "reboot into bootloader" in it, then flash stock kdz.

When I want to reboot into bootloader it simply boot the device.
I actually managed to install CM11 which should be more stable hopefully, but I don't know if it'll last long.
If I change the kernel, will it prevent kernel crashes?

Depends on kernel... I never heard of CM11's kernel crashing.

Okay so it should be good! Probably because Lollipop is a recent update on the G3 i don't know.
Okay well thanks for the replies!

Hello everyone.
I recently installed pureness build 14 sp1 and xarc kernel.
Everything works fine except one thing i noticed. When I hit the reboot option I get stuck in a reboot loop.
I have to enter CWM and select power off in order to be able to start my device.
Any suggestions?
reflash the rom
check compatibility kernel with rom
This is the only problem I faced so far I think I will use shut down and restart for the moment. I thought it was some setting that I wouldn't see.
Because a lot of people are using this combination I think it is not a matter of compatibility.
Keep in mind that I am a rookie at this and this is my first experience with custom roms and kernels
first step use stock kernel, try
Can you please provide me with a link to a stock kernel?

Hi, I have rooted my device and installed a custom recovery. But that's it, haven't installed any new ROM, and still have the stock one witch it came with.
Today I received an update message, so I downloaded the new update, and as it should be, it requested a reset.
After the reset, the device boot himself into the recovery, ans apparently refuses to boot into the new rom, or anywhere but the recovery.
I performed a full wipe, and did a system restore. And still it always boot into the recovery.
Its a "Team Win" recovery v2.6.3.2
Help please.

I dont remember man...
I last time I rooted a device it was a Galaxy S2, and I cracked opened the **** out of him, and something like this never happened to me..
As I told, I did a system restore, why it still doesnt boot anywhere beyond the recovery?
One more thing,
After I manage to turn it off, it starts immediately as I plug in the power, but stops on the "Logo" and with this title in the up right corner: "Secure boot error! Cause: Device Unlock, so Boot Success"
Thats it... got this message and doesnt boot... After I unplug the power, it boots into recovery, and only then (whie unplug) I can order it to power off.
Iam desperate..
Ok, now I think I am truly Fckd up...
I accidentally deleted the only restore file I had... witch didn't quit helped me the one time I launched it.. but anyways, now even this one is gone.
So now I stuck with god know what system.. (I did launched the restore, bit it didnt helped).
I do have a working recovery, and thats it. Please help me restore the device to fully stoke.

Not sure. I was thinking Mahdi or Cyanogenmod. A complete ROM. If the 4.4.2 is a complete ROM, then yes. The update you are trying won't affect the recovery, correct?

Yes.. the update didnt effected the recovery, and from my experience it shouldnt... (the update is for the ROM, witch was stock)
Thats why I didnt install a custom ROM from the beginning, I wanted a rooted device, but for now I wanted to stay with stock ROM. After receiving an update message, I didnt think for a second that the root and the custom recovery will effect the update...
Maybe this update had something to do with the recovery... and because mine is custom, I have this issue...
Iam not an expert in the LG field, so Iam not familiar with those effects, the update caused...
Can you please look at the installation guide in the link I gave, and check if it is doable on my device.
Thank you for the help! :good:

I think I need to be already rooted to use this method, dp I not ?
I need to root and install twrp.
When i had my G2, the forums was buzzing with new Roms, it was pretty much a bullet proof phone, i was hoping for the same with the G4, pretty gutted that its so quiet in these forums for this phone.

No. Just install twrp. Reboot into twrp and install supersu. Be sure to not let twrp auto-install anything to root your phone.

Hope your TWRP sticks, I'm new to this and it took me 3 attempts to get it to stick.
To get into recovery
Hold both power button and volume down button pressed
At first sight of LG logo release power button 1 second, Still holding volume down, then repress power button.
You should now get white screen with just 2 options, select "Reset" , Select with Power button, scroll with volume up/down
Again get white screen and confirm reset
If TWRP is on phone it should now appear.
If its not you are in for a Factory Reset
:
Now do a default backup in TWRP (very handy this)
Then move systemless root zip to phone.
In twrp select install find your "systemless root zip " flash , then reboot using "System" DO not accept option to root your phone offered after selecting- reboot>system.
Hope its goes well

I am on the same boat as OP. I unlocked the bootloader after updating to Marshmallow, so I didn't have TWRP from Lollipop. Now, even though it says that the flashing went okay, there is no recovery to boot into. Using "adb reboot recovery" it shows the android logo with the exclamation mark. If I do it using the hardware buttons, I get the LG's menu to wipe everything or exit.

If you have root there are many apps on play store such as : quick boot, simple boot, quick reboot. Install one of these and and they all all have options for reboot, hotboot, boot to recovery, etc. etc.
I have TWRP on my phone and if I use the standard way to enter recovery , power+volume down, then I will get the standard LG recovery screen but when I accept the recovery options there, it takes me to TWRP

That's the problem, I don't have root. I need TWRP to flash the SuperSU zip, don't I?
EDIT: Wait, do I need to say yes on the stock LG recovery first? The one that says wipe everything?

@ Dante897 No, if you don't have TWRP then don't. don't say yes to LG Recovery or you'll loose everything . You can also run TWRP on your PC and install systemless root zip that way. That maybe what I did, I can't exactly remember now.
I'm off to bed now, last night was a late night too.
I figured it out. You aren't supposed to flash the recovery., you are supposed to boot to it, flash SuperSU and then use Flashify to install TWRP. I did that, but I flashed the wrong SuperSU (I am an idiot I know) and my phone won't boot now. Currently I am in download mode and downloading the rom with LG Bridge . You can follow the guide here if you want http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241 but whatever you do DO NOT flash SuperSU 2.46, grab the newest from here http://forum.xda-developers.com/showpost.php?p=64161125&postcount=3
I cannot say that it will work, all I can tell you is that 2.46 certainly doesn't work.
EDIT: Alright, I let LG Bridge install the update, no wipe happened. I did the process again, this time I flashed SuperSU v2.62-3 and everything went well and my phone is now rooted.

I also had an issue with TWRP sticking. I followed someone else's tip and you have to have the twrp IMG saved on your computer and also on the phone before flashing recovery with fastboot.

Well let me explain. I wanted to tether, so I thought I would try and root and install a custom rom. I used Odin to install TWRP, downloaded NobleRom, thinking that it should work, flashed it and all it does it sit at the android screen when I boot up. I did a wipe and tried to install a "stock" rom that is apparently incompatible. My phone is a 920P. Currently lost and looking for direction for a slim, compatible rom that works.
HELP!

The reason your phone won't boot is due to the wrong kernel and even then won't boot (as I've tried). What I recommend you doing is booting into TWRP and installing Renegade ROM its is currently one of the only stable ROMs for our phone.

That's what the post above suggested. Thank you for explaining why. So from what you're saying, each rom is based on a particular Kernel? What other factors must be the same? I'm sorry if this is a dead horse, just new to me.

My phone is also rooted with MM fully working !
rooted, debloated by some apps like maps youtube and others I do not use, working buttery smooth. I`m also using Kernel Toolkit with Ondemand (maximum battery profile selected) and Row as I/O scheduler. Works so good man. Also compared to lollipop, it has some slight battery drain but selecting those configurations I stated seemed to help and now battery is good too.

Are you sure you're using the latest official TWRP image? For now, reboot to recovery via "adb reboot recovery" instead of the hardware keys.
