Flash kernel on top of kernel - G2 Q&A, Help & Troubleshooting

I searched for an answer and came up with nothing. I installed a kernel but want to go back to the one I really like. Can I flash it on top or do I need to factory reset and start over?

Trouble with phone after flashing.

So I have been flashing Roms since this phone has had the ability to. But recently I decided to flash a Google 4.2.2 ROM. Well, I can't flash any ROM except for Google 4.2.2 or 4.3 and its frustrating because I want to go back to AOKP. Any ideas how to fix this?

Also. To further clear it up. When I flash another ROM the phone sticks at the custom screen. Doesn't bootloop, doesn't shut off. Just sits there.

Which rom have you tried to flash? Also which S4 do you have?

Flash the rom back you wanted, and before you boot, FLASH THE AOSP ATT KERNEL FOR YOUR DEVICE. It will boot.
You did say aosp you wanted to go back to, if it is a TW rom, flash tw.
Thank you. Your Welcome.

Everything from Goldeneye to AOKP. But it just sits at the custom screen. And I have the I337 AT&T US.

I flash AOKP with the stock underwear kernel. I don't think that flashing the AOSP att kernel would effect it though. I've never ran into this problem with my past 3 phones. EVO 4G, EVO 4G LTE, and my SIII

You also didn't have locked bootloader on the others.
if you do not use loki doki or loki kernel, you will continue to hang at the boot screen.
Good point. I forgot about that.

Standard recovery image.

I flashed twrp on my Verizon LGG2. I was just wondering, since I have to have the standard recovery to get OTA updates(hopefully next one is Kit Kat), does anyone know where I can find it for my phone?

You will get kitkat much faster from the developers than you will an ota

Good to know, but doesn't answer my question.

Not sure, but I was wondering about this also. I think I'm just going to go back to stock when we get 4.4.

Anyone know the answer?

load the factory image using the LG tool. this will put you back to original stock, of course it will wipe your phone.
just an FYI, taking an OTA could possibly remove the ability to root your phone in the future. SO make sure that is really what you want.
I also have a similar question involving CWM. At the moment I have TWRP as my recovery (used flashify to install it), however I would prefer to use CWM. If I flash CWM via flashify, will it replace TWRP?

there is no reason why it shouldn't as far as I know, i've had twrp and have flashed cwm but am now back with twrp,just make sure it's the latest for your phone.

Awesome, thanks. I'm new to the LG phones (been on moto for the last few years) and just wanted to make sure

So is there any way to get standard recovery without having to reflash the entire stock rom?

4.4 Stock Kernel Question?

Is the stock kernel available for Kitkat? I thought about trying another kernel but hat the thought of having to restore a backup or fish the factory image again. I am running stock rooted Kitkat
Sent from my VS980 4G using Tapatalk
Its the wrong section mate. But here is the stock one. I made a flashable zip. Should work.
Sorry man. Thank you though. I didn't pay enough attention. Hopefully a mod can move this.

The above link works just fine, but in adition I would recomend you to check Nexus Root Toolkit, from our member WugFresh. It has you covered in pretty much anything you can do with your nexus device regarding flashing, restoring, backuping , etc...

Vs980 where to go from here?

I finally decided to drop my beloved galaxy nexus. The N5 seemed like the next phone of my dreams but couldn't stand the thought of losing my unlimited plan so G2 seemed like the next logical choice. I have been reading as much as I can and still having a hard time wrapping my head around things. Here is where I am at:
Bought phone from swappa appeared to be in new condition as advertised with plastic still on the phone.
Not sure if the phone was updated ota by the seller but the software and baseband were 12b out the box not rooted.
I rooted successfully with latest I0root method.
Installed loki patched twrp 2.6.3.3 successfully via freegee method. Full nand backup of rooted stock. Backed up imie with freegee and imie and other partitions via flashable zip method.
So where do I go from here? Is it safe to flash any VS980 rom from this point?

Bump for this? Anyone have an answer?

I have yet to install a custom rom or I could let you know. I have however upgraded to philz recovery and successfully installed dorimanx kernels. Got a little busy messing with exposed modules as well. I wanted to make sure I have all my essentials backed up before messing with roms and have the appropriate files and drivers working in case something goes wrong. I tried to install malladus yesterday and the install failed but I want to say the download was bad as it took forever. I had no issues with restore. I'll report back if I have any luck.

If you want some KitKat love, try out Mahdi ROM with the latest furnace kernel. Very very stable on my vs980.
Sent from my LG-VS980 using Tapatalk
You've bought the right device, aside from some unreleased phone of course. I too came from the gnex and I love this thing. Go install some AOSP ROM and it will be like you never left the gnex. (Although admittedly not as stable YET). With KK just being released by LG, all roms should get better. Anyways, enjoy a camera that works all the time not just when it is super bright and a battery that is equal to 3x of the galaxy nexus.
Sent from my LG-VS980 using Tapatalk
Thanks for the input. I installed AICP latest ROM last night with no issues. Feels amazing with no scroll lag compared to stock. Only thing I miss is knock off but hey you can't have it all. Gonna give furnace a go later.

I thought Mahdi came with knock on?

LG G2 won't rotate. HELP

So for some reason my screen won't rotate into landscape mode. I have the rotation setting turned on but nothing happens. And when I try to calibrate my sensor, the settings app force closes. Any ideas?

Any more information Rom, what did you come from etc

Just stock 12b. I'm beginning to think it might be the modem. Because I was lending a hand a experimenting with the 24a kitkat build for the VS980 and had to flash a kk modem to be able to boot into the build. Do you think the modem would screw with rotation settings?

Yes it's definitely the modem I've read some people tried the kk modem and in order for rotation to continue to work had to continue using the kk modem or downgrade via flashtool

How do you downgrade via flashtool? I just went into recovery and flashed the 12b modem and rotation still doesn't work.
Sent from my VS980 4G using Tapatalk
Flashing back an old radio works fine for me, have you tried that? no need to use LG flash tools if you can simply just flash the modem via recovery.
Going to try the kk modem I flashed yesterday.

I had an issue where I was on cm11 with rotation working completely fine and then decided to try a stock KitKat ROM. After reverting back to cm my rotation was broken. I tried everything you could imagine aside from going through the whole starting from scratch bs.. So I tried one last thing and it worked! I simply flashed my stock T-Mobile modem that's supposed to break rotation but funny enough it fixed it! Try that and see if it helps from now on.
