Guys, I am going to continue trying to level this nonsense out. Unfortunately not all roms went the same route for how their kernel works and what bootloader is required. I will do what I can to bring some harmony about but I'd this continues, I will just continue to release and not worry about these other issues. It's getting ridiculous and its getting more and more frustrating. Just keep trying and reporting what you find. At the moment I am using temasek with 0 issues.

Quick and short impression of R2

Tested with F320S and BlissPop 3.8 0804 build

Well, I didn't need any kitkat bootloader for install. I just flashed R2. Of course F320 was on Loki LP bootstack.

It booted without any problem, so I was surprised. I didn't test other roms but BlissPop just worked.

Because BlissPop includes kernel auditor as a system app, I just utilized it.

What I found was Max CPU freq clock doesn't exceed 1574MHz, no matter what I set. It just kept returning to 1574MHz.

When I used geekbeench 3 with changing cpu gov and hotplug, overall score was behind what I saw in normal stock kernel, maybe meaning governer and hotplug restrain cpu usage. I think this is good for battery save.

But even when I used performace governer without hotplug, the score was too far low. This is all I found.

After overwriting stock blisspop kernel to go back, I found hotplug was gone.

I recommend when you try render kernel, be prepared in advance.

Except that, R2 is much stable than R1.

for F320, Kernel mounts external SD memory. :)

Can you post a link to the bootloader and LP bump you're using? I'd like to try it. Also, if you have to delete kernel Adiutor to get it working then you'll need to delete every time you flash as its built into the ROM.

Just for testing I flashed another Kernel. It worked on LP Bump Bootstack and KK Bootloader (dorimanx) so went to TWRP and flashed R2 bu it didn't worked again. Wiping cache and dalvik or everytime flashing bootstack and KK Bootloader again is a really hard procedure. I hope you can find a real fix for that. [MENTION=5438598]RenderBroken[/MENTION]

Sounds like the Thermal Driver is throttling you. Max freq works fine and sticks to whatever you set it to. Still Thanks for the report but def sure that its the thermal driver throttling you. ;)

I hope I can find a solution too. Also I don't wipe dalvic/cache. Its not really needed. Also I would argue that flashing bootstack, bootloader, then kernel is a difficult procedure. I would say that its unneeded though. The amount of hoops to jump through is ridiculous. One things for sure is, I would hate to drop all support for the g2 due to such ridiculousness. Still I am hard headed and persistent and feel I will be able to get it but keep in mind that there really is no gains (Not just monetarily) to spending all my free time trying to plug a leaking dam.

Thanks for the vid though. That is similar to what I am seeing as well. I had that problem on SlimSaber.

Not sure. I do know that it works with the CAF Version of Temasek!

I just tried Temasek's UNOFFICIAL CAF CM12.1 on my d803 and it still bootloops once it hits the boot animation. Any chance the d803 has a slightly different requirement from the kernel due to not having any LP bootstack or bootloaders?

We're all hoping you can figure this out and considering my variant doesn't even have any official LP I'm thankful for any work you're doing for it, whether it works or not. :)

Hi Render,

I really appreciate you as a dev and as a person (most friendly and patient dev ever) you did bring a lot to the G2 xda sub forums and still bringing it, that is why you became a recognized dev on XDA.

And spending so much of your free time for us is just generous from your side. We can not demand you to spend a lot of your time, do not get frustrated, just take it easy and work on the kernel little by little when you feel like it, maybe that way we are not going to loose you here on LG G2 xda... We can wait :)

Use xdabbebs or get the LP one from rasheds bootstack thread. Apparently both the bump and Loki that everyone has been using has been using a 4.2 aboot.
[G2 Android Development] RenderBroken:
I am currently using Bump with Anykernel. My understanding is it should work on both JB and KK Bootloaders. Try DrGravy's and let me know. Try his Bumped Bootstack.

See this is whats crazy, I can have the same model, flash the same rom, but have different results. If you were to look at the last 10 pages, you couldnt not make any sense of what the common thread is or what it is that makes those that work, work. I am going to be putting together a spread sheet guys so I really need as much detail about what worked or didnt work. What I need is in this order:

Phone Model

What bootstack you used (Link Preferable)

If you had to also change the bootloader (D802) Please link that as well

What Rom you flashed - I need to know the build date if possible

Here is the spread sheet guys. Please fill this out. It would help me greatly!

Bootstack is bumped from http://xdaforums.com/showthread.php?t=3173715

R2 on D802 with BlissPop 3.6

Here's what worked for my phone:

1) Flash Rashed97's LP Bumped!!! Bootstack

2) Flash Dorimanx KK 20H Bootloader (Bootstack in 1) must be bumped!!!)

3)Flash R2 Kernel

+ when necessary UKM

What I noticed:

-Thermal Options in Synapse are missing (no options available)

- Voltages can't be set freely. When I change 300 MHz from 775mV to 700mV, I have to do this in steps with 5-10mV, otherwise it jumps back to the last value.

- Some of the voltages are reverted to default after reboot.

- In KK Kernel there has been an Option to manually set the loading current, i really miss that option and would really like to see a comeback in LP :).

Thanks Render :D

[MENTION=5438598]RenderBroken[/MENTION] That's because more than half of the cummunity that SHOULD know what's going on, doesnt understand their ass from a hole in the ground.

Long version - Rashed put out bootstacks one named bump and one named loki, his versions had broken DL mode, so DrGravy made a set which is a complete copy, that had DL mode working. You would think that the "bump" version would have a 4.4 aboot, but for whatever reason both of them had the 4.2 Aboot in them. First time i tried to flash your kernel i got nothing but the black screen, then i read you stated yours is made to work on the 4.4 aboot, so i tried xdabbeb's bootstck which i was 100% sure it was on the 4.4 aboot and it worked fine. (to anyone that reads this, this bootstack is vs980 ONLY)

So, Rashed opened up a thread for the bootstacks, and he did make a bump version thats on the 4.4 aboot, loki is 4.2 ect. I tried that bootstack, and have been using it ever since, no issue.

TLDR: If you are on a vs980, use xdabbeb's or the bump bootstack from Rasheds thread.

If youre not on a vs980, go to rasheds thread, im not sure who has made you guys what as far as bootloaders, but i can confirm that Rasheds works

Hi Render i've tried your r2 on resurrection remix but the frequenzy doesn't go over 1.5 ghz(at 50 celsius degree so i don't think that this issue are related to overheat) and in kernel adiutor setting there isn't any option regard termal driver
[G2 Android Development] RenderBroken:
Please get me logs. I am fairly certain its due to Thermal. If you want to change the thermal settings look here:

/sys/kernel/msm_thermal

Still logs would confirm. Main thing is I am using R2 (Along with many others) and have n such issue until the thermal driver kicks in. For the record. The Max freq gets locked to 1.57GHz when Temps are between 48 - 54 Degrees Celcius. I plan on adjusting it so its not so oversealous.

Bliss was clean installed yesterday. Then R1 kernel was installed after booting into the ROM. R2 was installed this evening over top.

MSM hotplug is working correctly, with 1-4 cores being online as needed.

MSM_Limiter doesn't already to be working, though. Min freq is always 300 MHz (as shown in cpu info overlay) and max freq is always 1.5 GH, even though Synapse is showing it to be set at 1.9 GHz or 2.2 GHz. (I'll attach a log after posting.) CPU temp is 45-55 C currently.

Edit: oh, and the SoD appears to have been banished. :)

We're getting closer to everything being perfect. :) Keep at it. :D

Edit 2: logs attached. Been running for 10 minutes or so, screen on/off a few times, doing stuff to online/offline cores. Hopefully there's something useful in there about the max freq being limited.

What exactly is it doing? is it some addon for synapse or something?
[G2 Android Development] ZeNiXxX:
hey guys

maybe someone can help me. I really want to use this kernel but I don't get it work with my device.

I'm on Blisspop 3.8 (d802) and currently on ethernal kernel. I've used all kind of combination with kk bootloader and bumb lp bootstack etc.

I've tried to kk 20H, 20D and lp bumb bootstack ( find it here in forum ).After that I've flashed kernel v2. But I always ended up in bootloop... I can't access recovery however I've tried it... to solve that I need to Flash kdz rom and than to setup all again ( and all data are gone than.)

So have I to flash first lollipop bump bootstack than kk bootloader or first kk bootloader and than lp bump bootstack?

edit: v1 booted fine with kk bootloader... but v2 doesn't work for me.

Hi Render,

I wanted really to try R2 and after not being successful with the Bumped LP Bootstack and KK Bootloader from Dori on my D802 with SlimSaber latest I decided to give it another try and wiped everything (without internal storage) installed latest Rashed LP Bumped Bootstack which has integrated KK Bootloader, after that installed SlimSaber, Gapps,SuperSU and set up my device, cleared cache of Kernel Auditor and uninstalled it, got to latest TWRP 2.8.7.1, cleare cache and davlik cache and flashed R2 after that the phone is getting to the LG logo for a second and goes to black screen, there is no way to go to TWRP, no mater if I am pressing the power button for long time or trying to go to TWRP - all the time the result is LG logo for a second and black screen. The good news for me is that I can go to download mode and I get the firmware upgrade screen the red sign ROOTED. I will see if I can manage to do the KDZ instalation, so maybe I am not getting a hard brick here...

I am sure that it is not kernel fault, maybe something got messed up in flashing or I got some corruption in internal storage or mmc, just wanted to report the steps that got me to here.

Your kernel is the best I used and if I manage to revive my device I will keep trying to find a way to use it :)
[G2 Android Development] ZeNiXxX:
finally I got it.

Solution: The issue was wrong lp bootstack !

It seems that some lp bootstack are mixed up !! my previous lp bootstack I've used was called " bootstack-d802-LP_30d-Bump-signed.zip " .... But when I flashed it the recovery script tells me " installing d800 bootstack ".... so I've downloaded a other version of lp bootstack from render spread sheet, installed it than installed renders kernel and than kk bootloader 20H.

Now it's booted and it's seems to be smooth. no sleep issues.

@ render. will you add some governors back ( lionheart, nightmare and so)?

Smartmax gives me nice results,too but I just wanted to know :).

thank you for that kernel

D801 running latest CM12.1 Nightly (8-11-15), Render R2 CAF kernel, drgravy LP bump bootstack, synapse, ukm and everything is running well.

Installing apks seems slower than Temaseks ROM/kernel, I tried rebooting before finishing all the apks and it was still on the slow side, so I guess its a governor/scheduler setting that might be holding it back. Otherwise the phone seems very stable. The other day I watched a couple x265 tv shows on Temaseks ROM/kernel and the phone got very warm, today I watched again a couple episodes and the phone didn't get as warm (same encoding and tv show series) with the Render kernel.

I miss some of the tweaks from the Temasek rom, like the ability to close all the resent programs all at once. I don't know if you can add that? :)

Mate, I manage to revive my device and because I am stubborn I gave it one more try, to see am I going to brick my device again, following the same procedure :silly: :o

Rashed latest LP Bumped D802 Bootstack + Dori KK Bootloader + SlimSaber = freeze on the startup screen (I uninstalled again Kernel Auditor, wiped cache and davlik cache also).

And then I did try other method full wipe and only Rashed Bumped D802 Bootstack + SlimSaber = the same result.

I guess there is something really deep in SlimSaber that conflicts with R1 and R2 or my LG G2 D802 is crazy in some aosp way, hahahahh,

[G2 Android Development] sdeft:
Please be aware that both bootstacks from lg-devs use the same aboot which is not bumped but lokied as it is the JB one.

Do a file comparison of aboot and you will get that both files are the same. If you want to test the KK aboot which is bumped I suggest you use the one from AutoRec LP version.

Furthermore the bootstack is just an extraction of partitions from stock KDZ file with a modified aboot. My understanding is that the other files in the bootstack are not patched. Please correct me if I am wrong.
[G2 Android Development] RenderBroken:
Honestly, bump should work on both JB and kk bootloaders. Loki is the one that will only work with JB. So it SHOULDN'T matter but you never know anymore. . . .
