I really don't know why your phone has so many issues with my kernel when it works fine for other D802 users. I really wish I could find the difference. Its really interesting. But are you using darkobas rom with my kernel or stock?
[G2 Android Development] lambo98:
what is different between loki and oc?
[G2 Android Development] ZeNiXxX:
that's strange with. your kernel I have the best performance and battery life I've ever had. ( after an update of my Tastatur) it totally smooth now. I can write totally fast now :). I've tried 5 different lollipop roms and always use render kernel and never have a problem....

how about backing up all important files and completely Format your phone? data / internal storage /system/ cache/ dalvik cache ?

maybe there are some old files that make problems ?

---------- Post added at 05:56 AM ---------- Previous post was at 05:49 AM ----------

can't confirm that... such battery usage isn't related to the Kernel... it seems that there I'd something that "eats" your battery power.

please use apps Like betterbatterystats or wakelock detector or so....

i have D802. and i m using R7 build.

i didn't made any changes was trying to test with stock settings.
[G2 Android Development] RenderBroken:
Then something else you are adding to the Rom Kernel mix is the cause. I can tell you with out a single doubt that my kernel is not the cause if you are using stock settings. The reason being I have made the default settings for R7 VERY Conservative. More so than any kernel out there. So the fact that your batterylife is horrible leads me to think that some app or service is the cause. Install and app like GSAM and tell me what the top 5 causes of battery loss are. That will help us narrow it down. Thanks.

As far as the volume going dead loud on Bluetooth goes, I changed the volume steps to 7. (With RR rom) Not had it occur again.

my wife and i run the same rom and your r5 kernel. we both have the echo. r7 didn't hold any profiles for us. so its not just my g2, its hers to.
[G2 Android Development] KingVekxin:
Hey I flashed the most recent official build for th VS980 4G, installed renders kernel because I saw that was a workaround for the bootloop issue some of us were having. Now my question exactly what setting control the CPU governors because I've seen at least 2 or 3 gov settings but I'm not sure which settings exactly set the bar and have them stick? Can anyone chime in on this at all?
[G2 Android Development] RenderBroken:
Does she have the same model? Also its known that R7 , profiles are not working yet. I am focusing on fixing that for R8. Also regardless that it happens to your wife's phone, y'all are still in the very small minority (of those that have at least reported it) so it leads me to believe that its some specific thing y'all are doing that is triggering it. Am I gonna say that my kernel is bullet proof, no. LP as a whole is still very alpha. We are still using vendor blobs for JB! I imagine things have changes since JB but that's what we have to work with. So there may be an underlying issue but I still think its something, some setting change, whatever that is causing it to trigger for you guys. I would love to find out what it is because I cannot make it happen on my phone. I messed with tons of sound settings. But if you could get some logs with Syslog like immediately or soon after it happens, that would be awesome.
[G2 Android Development] RenderBroken:
I am not quite sure what you are asking. So I will ramble. If you want to adjust kernel settings use Synapse. Its like TricksterMod on steroids. If that is too much then just use Trickstermod. Both are great.
[G2 Android Development] hotrodwinston:
bad download?

These random people having issues could be a bad download. [MENTION=5438598]RenderBroken[/MENTION] do you have the md5 checksums handy so the people having issues can redownload and check md5 before flashing again to see if the problem persists?
[G2 Android Development] RenderBroken:
Yea I believe they are on the main site

You just need to hit the "I" icon to the far right of the file.

Hate Synapse. I was having trouble raising my headphone volume even with adjusting mixer paths. So I purchased and tried FauxSound. Wow! Just exactly what I needed! So I went ahead and used his kernel app I'd purchased in the past, and now I'm good to go!

I'm really a happy clam with your R7 on BlissPop, thanks! Only thing that would make me happier will be when djdarkknight's KlearKat gets updated to lollipop.

LG G2 VS980
[G2 Android Development] RenderBroken:
Yea, Synapse is not for everyone but I would not be able to add in the features I do without it. I could do so but then I would have to have everyone control it via command line and sysfs. That's not impossible but the everyday user couldn't do it. Still there are many other options out there. Synapse is not the only one and users still have a choice. Glad things are working well for you! Also I too use Faux's Sound App.
[G2 Android Development] TDSJR:
Check ALL of your volumes. Some of the defaults are way too high for this phone. I use the FauxSound app to tweak telephony volumes and have amazing clarity on both ends, just takes a little bit of playing.

[G2 Android Development] RenderBroken:
Yea I though I would try some settings from the N5 to see how well they play and for most its fine but not all. So I will most likely just be reverting some changes for R8. I am currently work on it now.
[G2 Android Development] MrDarkKV:
Hello all, after a lengthy investigation I've concluded any download issues a minority of people are having are client side related. Due to the amount of people (zero) who actually provided logs of the issue on their end, any further reports of download issues (unless there's maintenence) will be dismissed as client side. I've done everything on my end to ensure all downloads are successful including revising the servers OS to a more stable branch. I recommend that people also check the MD5 of the file they downloaded and that it matches the MD5 of the file shown on the server (pressing the "i" on the right of the file on a desktop) to ensure a successful flash.

Sorry if this sounds a bit harsh, but people complaining their having issues downloading and then not providing any info to help resolve the issue doesn't help me at all.

Thanks for understanding and if you do actually want to contribute to resolve any issues which may be effecting you please visit this link:

Hey guys,

I have a spot available on a Super Build Server for just $30 a month. The specs are freaking awesome! I bought in to try it out and loved it but its WAY too overkill for my kernel work. Especially since I already had a VPS. But for those of you Building Roms. This is a fantastic setup on the cheap! If interested PM me and I will get you in touch with the ppl. Its a professional setup with billing and all. So if you are not happy you can leave anytime. Its billed monthly. Just let me know.

Specs:

CPU:

Intel Xeon

2x E5-2670v2

20c/40t 2,5 GHz+/3,3 GHz+

RAM:

256 GB DDR3 ECC 1600MHz

Disks:

2x 2 TB SATA3

1Gig connection

You share the server with other users but its limited so as to not slow the server down. To put things into perspective. To build a full rom it takes about 15 -20 minutes. 15-20 MINUTES!!!!!!!!! So yea, just a little overkill for kernel work lol. Check it out guys! I just enjoyed the other users on the server and want to help by filling the now empty spot.

The gpu and cpu settings wouldnt stick.
[G2 Android Development] RenderBroken:
You talking about Min CPU? That is a known issue. It is the way CPU Boost works and boosts min CPU. So when you touch the check mark to apply it, you just touched the screen thus boosting min CPU. Also the same think happens with GPU. Even though the Max Freq is only 450MHz it will always show 600 even though its not used. Not really sure why it does that but I am sure its a false reading. You can look at the SYSFS file controlling MAX Freq for GPU and it shows correctly. Are these what you are talking about?

I appreciate you telling me because I do want to fix any little bug if its in my power to do so.

R7

Hi Render, may I know why the thread title is stuck at R6 and not R7? Could it be that you know that R7 is unstable? Well, I'm one of those people who have issues with R7. R7 gives me massive lag after a few minutes of use and only a reboot remedies this temporarily. R6 is working great for me though. Could it be that R7 is too conservative? I have done clean flashes on multiple ROMs and I have checked the MD5 multiple times. Don't get me wrong, I really want the best for this kernel and I love this kernel. However I highly doubt so many people have bad downloads on R7 and not R6 and other ROMs. Thanks for your hardwork.

P.S. Could you share some insights on why CM12 18/01 boots only with your kernel and not the kernel baked with the ROM?

F2FS Testing and Comparison

hope this help

R26 Kernel + Liquid Smooth Milestone

/system=F2FS (if i used EXT4 on R26 and LS, after booting-up it asked to "Type Password To Decrypt Storage")

/cache=F2FS

/data=F2FS

1. No Baseband

2. Rotation not working

3. Internal Storage can't be accessed

bart452 Kernel + Liquid Smooth Milestone

/system=EXT4 (formatted to ext4 coz im stock on LG Logo if the file system is F2FS)

/cache=F2FS

/data=F2FS

1. Baseband is Good

2. Rotation Not Working

3. i can access Internal Storage

4. the phone hangs while Shutting Down or Restarting the Phone

Note: at first i'm using the same baseband for both Kernel then switch to dr87 Baseband (rotation problem is still there)

if all file system is on EXT4 i have no Rotation Problem (strange)

while i'm on R26 i can't use Screen Capture co'z it cant write to Internal Storage so i just used Android Device Monitor on my PC for Screen Capturing.

P.S. excuse my english grammar ;)
[G2 Android Development] RenderBroken:
REALLY great info!! I appreciate you doing this and getting me proper logs! So to me it looks like the scripts are not working perfectly. At least not for KK since that's all I saw. I was actually working on re-working how the F2FS scripts worked for R27 KK and R8 LP. I will send you a link to test tomorrow if you are up for it. Once again, Thanks for doing such great tests and providing solid info!
[G2 Android Development] TheSpaceManatee:
Thanks for clearing things up, it could be something on my end hmm.. But the lag does go away when downgrading to R6. But I'm sure R8 will be a fantastic release :) Kudos to your great work!

The kernel comes with 18/01 CM12 and its a very well known issue. I think Steve Kondik said on G+ that CM12 is currently undergoing lots of changes and will inevitably break and fix stuff

Hey guys,

I just wanted to point out that [MENTION=5141006]MrDarkKV[/MENTION] and I have adjusted the link for downloads. I decided to buy a domain name (renderserver.net) and wanted to simplify things a little bit. Right now the link to downloads is:

[G2 Android Development] RenderBroken:
Working on R8 right now.

Things I am working on:

F2FS

Kexec - See Below

Sound Control

Profile support in Synapse

I will add in some other minor changes after these are done.

I will note that using the Automount scripts will not allow MultiRom to work right. I have been informed of this by Neobuddy89 which is a trusted source. I will see if there is a work around but doubt it. I also believe this is why Kexec is not working for you guys. I guess i will have to build separate kernels just to support Multirom. Its not like I dont have enough kernel to build. lol

Still with no Ubuntu or another other REAL different OS for the G2 I find MultiRom useless. On my N7 2013 with Ubuntu Desktop running on it for work and Android for Play. Sure. but to install another Android Rom, not really worth it in my opinion.
[G2 Android Development] luv2increase:
I thought you fixed f2fs in r7?
[G2 Android Development] heleos:
F2fs wasn't working properly for mounting certain partitions. Cache worked, but I don't think data did
[G2 Android Development] RenderBroken:
I am looking into why /data is not working properly. Its weird because we know F2FS works because /cache mounts properly as F2FS. We also know that the scripts work otherwise the rom wouldn't boot period. So I am trying to find the fail point. Should be an easy fix, just have to find it.
[G2 Android Development] abdel12345:
So is r7 good to flash for now. I've been away from this thread for a bit and have been using r6 for a while and I notice r6 is still in title. So should we just skip 7 and wait for 8? And also can you update link in op with new one for lollipop section? It still goes to old domain. Thanks

Also I agree on the multirom point. Only way I'd find it useful without another os like Ubuntu would be if you could flash a KitKat and a lollipop ROM on it but I think as of now we can't.

Sent from my LG-VS980
[G2 Android Development] luv2increase:
If it is a needle in a haystack, just release r8 without that and r9 right after you find the culprit. That is the same thing you did with r6 and r7, albeit it f2fs and /cache.. Of course, that is probably easier said that done. I wouldn't want for you to go through all the hassle of building all those different kernels for all the g2 variants twice when we all could've just waited another day.

Keep up the good work! We know you will fix it. This waiting on r8 has been therapy for me in patience lol!!!

How do I F2FS?

Alright noob question here, I think the community here isn't that ragy so I'd like to try my luck here. Can anyone explain what do I need to get F2FS working and how do I it? If no one has time to explain here, can someone link me? From my understanding I need blastagator's F2FS compatible recovery and once this kernel becomes F2FS stable, Render Kernel. Will any ROM work fine with F2FS? What exactly does F2FS do besides speeding things up?
[G2 Android Development] Formhault:
Is F2FS really worth it? Please tell me how does the phone do better (in terms of performance / battery life (?)) with F2FS instead of EXT4. I am really curious, because so far, F2FS isn't that much better over EXT4, and I really don't see why you people would STRUGGLE SO FREAKING MUCH to achieve... well... nothing, apparently.

A benchmark which shows small improvement does not mean EVERYONE SHOULD JUMP SHIP AND OH MY GOD IT'S SO AWESOME KILL ALL THE THINGS IN THE QUEST TO F2FS. Cause that's pretty much what's going on lately.

---------- Post added at 04:31 PM ---------- Previous post was at 04:31 PM ----------

The same answer as 6 months ago.

---------- Post added at 04:34 PM ---------- Previous post was at 04:31 PM ----------

I want someone to perform an in-depth EXT4 to F2FS comparison. FOR THE G2.

Oh and real life tests, too, like opening applications, phone startup, file transfer speeds.

The results will show that it is not worth the hassle of getting your phone from EXT4 over to F2FS.

If all it would take is a push of a button, then yes, moving over from EXT4 to F2FS would make much sense. Because the factor "hassle" would no longer be a... well, factor.
[G2 Android Development] heleos:
Render is actually putting all the work in for you, so it literally is a push of the button for you. I moved my cache over to f2fs a few weeks ago. Do I see a gigantic improvement? No. Will I see one when I move over data and system? Probably not. Do I like trying out newer systems, especially ones designed for this type of hardware, and tinkering around with my phone? Absolutely. And I know I'm not alone, this is what most people come to xda for. We're android enthusiasts

It is counterproductive to move /system over to f2fs. It is beneficial however to move /data and /cache over to f2fs.

[G2 Android Development] RenderBroken:
When I release R8 I will write up a Tutorial on how you can setup F2FS. Just hang tight a bit longer and you will see that its pretty easy.

F2FS is not why R8 is not released yet, I am a multi tasker (you know lol) and I am working on a number of things for R8. So far I have updated the Ramdisk to work with newer LP Roms, Working on Sound Control, F2FS, and Synapse profile support and having the ability to reset all Changes made by the user with just a single button push.

In regards to F2FS, Why flash my kernel over Stock Kernel? Because its better, in a measurable way. Why would I go to F2FS on all partitions? Because its better in a measurable way. I have seen some astounding benchmarks on even new hardware. But even if its a small benefit, it is still a benefit. Thats why we flash aftermarket firmware and kernels, to eek out as much performance as possible. Also what is not really shown is the positive effect on battery life that F2FS has. Is it much, no, but its still better. Whatever I can do to make my phone stay relevant and competing, I will do just like any user out there.

"Render Kernel - keeping your phone from becoming obsolete"
[G2 Android Development] Formhault:
lol k
[G2 Android Development] carlos67:
Must say I agreed with [MENTION=4129455]Formhault[/MENTION] about f2fs but after reading the OP's reasoning here, I now understand and support his endeavours. He makes a compelling case for it.

My biggest hope for R8 is better integration with Synapse. At the moment it is hit and miss as to whether my synapse profile gets applied on reboot/boot-up. Sometimes I get "synapse boot completed" while other times I get nothing or maybe "synapse boot cancelled". It's a real, inconsistent pain in the arse. I'm so hoping that it's better in R8.

Also, I'm really hoping that R8 is tuned more towards performance rather than the very Conservative R7 is.

Lastly, Blisspop ROM now comes with Render kernel baked in! It's an excellent, stable LP ROM.

Edit: suggestions welcome for how to ensure synapse profile gets applied on every boot/reboot. I've tried most things like clearing data and reinstalling synapse. Tried removing su perms and re-granting in Supersu. Nothing seems to make it apply profiles consistently. Arrrrrg!
[G2 Android Development] heleos:
I think you'll still have to flash render kernel separately, otherwise synapse won't work at all
[G2 Android Development] drivenby:
I don't think f2fs will bring much to the g2.

Like, If it's not TOO MUCH hassle, then you should do it Render, it is a (benchmark) measurable improvement, even if real life tests haven't been thorough yet.

But I can see where Form is coming from, cause I've seen like dozens and dozens of users messing with f2fs for dozens of hours, for a benchmark improvement that might or might not improve things in a real life setting.

It's just the cool new thing to try, and I'm willing to try it, but again, if it's not too much of a hassle for you Render. You already have tons of (nonpaid) work! :)

And to the people that are fighting the benchmark wars....

You know I've seen pretty much every custom kernel dev saying stuff like "benchmarks don't matter" ... But they do when I'm trying to prove a point?
