Hells,

I liked the boost framework you used in previous builds that didn't change the min freq. I believe you said that you like it better. I could be wrong. It is possible to change the next build to that framework? People would stop to question about the min freq, and this framework probably won't make the kernel any more unstable... Just a thought :)

Running the latest build without any problem.
[Nexus 4 General] hellsgod:
The problem is, since I removed the boost framework from msm_mpdecision, people began to have more SoD's. I switched back to it to see if its because of that. So if the SoD's disappears I won't switch again, sorry :)

I'm trying a different ROM right now, so I will test the new build.

I know a lot of people are using Euphoria (I was as well) so I'll test with this new ROM and see if the same issues occur, to try to rile out any issues with the kernel not getting along well with specific ROMs.
[Nexus 4 General] bart.found:
Hi, I never had a SOD in build 75, thank you for the fast update to build 78, because b77 was causing playback issues! ;)

Only a little curiosity.. does this kernel have "vdd voltage boost" feature? I think not.. because my phone can't handle the same voltages I've ever used with other kernels, but I have to raise them by 20mV to avoid freezes and reboots!!

Anyway, great job, and thank you for supporting this "old" awesome device! ;)

I tried with VLC and had no problems with b77. YouTube on Firefox is ok too. Running latest MinOs.

why u remove consentrative from b75??i really love the SOT i can get with B75 hmm
[Nexus 4 General] Stevica Smederevac:
B78 has conservative governor so update;)
[Nexus 4 General] Selmak:
So far no SODs on b78. I even went back to one active core when idle. I previously bumped up to two in an effort to stop the SODs. The only other change I made was going back from the hybrid 1.07 LTE radio to stock. I may try the hybrid radio again, and see if the SODs come back.
[Nexus 4 General] miomabusy:
Just a clarification, b78 is compiled with ubertc right?

I think I need to use hellscore again *battery life issues*

Running chroma with b75. No sod here as well. Gonna try out the latest b78 later. From what I read, most ppl have sod on euphoria..may be the rom.
[Nexus 4 General] Selmak:
So I reinstalled the 33/107 hybrid radio, and a couple hours later I get a SOD. I'm on CM 12.1 with b78. On the standard 107 radio I tried for the last day I didn't get any SODs. How many others that are getting SODs are using a hybrid LTE radio?
[Nexus 4 General] miomabusy:
Euphoria Ubertc build and b78 stock, so far no problem. Play services wakeup disabled.

Can you link me the BatMax profile? I want to try.

EDIT: Nvm, I found it xD

Thank you buddy.
[Nexus 4 General] Selmak:
And a couple hours later another SOD. So I flashed back to the stock radio again, and will report back tomorrow.
[Nexus 4 General] mymeatb18:
I think the issue is related to min freq. If I raise it to 243 no sod. Lower back to 189 I will have at least 1 or 2 sod in the day. I'm on cm, b78, -100mv, max 1350 no touchboost, min core 1 max 4
[Nexus 4 General] manpildo:
b78, 384min-1512max, -75mv, event boost enabled, intelliactive, stock 1.07 radio, play services wakelock disabled - no SODs so far.

Btw, SODs aren't linked to only min frequency. I never use freqs lower than 384 and it didn't help me before.

[Nexus 4 General] ju1da:
Euphoria running well, no fc. Why playstore FC should be related to kernel? Maybe your rom/ settings

[Nexus 4 General] LolHacker17:
Yeahh thats true butt conservative on b78 is lagg
[Nexus 4 General] poondog:
Have you got boost on your hotplug driver turned on? If not, leave it on

Conservative in the previous one you said is smooth is because the governor has inbuilt boosting (like interactive and ondemand do)

Now the input boost is back in the hotplug driver (like it is on stock) so the governor doesn't need it. If you have it on, maybe increase it to the same as it was on the previous in the governor
[Nexus 4 General] nicobrazell:
new to this kernel 😊

Hi there guys. I'm using hellscore kernel manager. What setting should I use or modify here for better battery life? I used my phone all day with the stock settings, everything's smooth and fine but I only got 3hrs SOT. Thanks. Newbie :confused:
[Nexus 4 General] dcop7:
SOT is not an indicator of good battery life. But you can underclock for an example. The rest, default is pretty good.
[Nexus 4 General] hellsgod:
If you underclock too much you'll get worse battery life. Its not that easy ;)

hells
[Nexus 4 General] dcop7:
Yeah, you are correct :) I usally underclock between 12 and 1.4 GHz. But actually, I didn't found that helps that much with the battery with my usage :)
[Nexus 4 General] ju1da:
Did you change something to Google play services (app ops)? If yes, set it to default, maybe that's the cause. Honestly, I don't find any reasonable reason why hc kernel cause your Gplay FC. I have been using it for months, fyi.
[Nexus 4 General] Selmak:
After flashing back to the stock radio again yesterday afternoon I made it through to today with no SODs. I am now convinced that it is the hybrid LTE radio causing the SODs, and not the ROM, or the kernel.

I can almost eliminate the SODs with the hybrid radio by bumping up the min freq, and setting minimum cores to 2, but I think I have decided that it isn't worth it. Honestly HSPA+ is fast enough for my purposes, and I will likely buy a new phone when the next Nexus comes out. Well that is if it isn't huge like the Nexus 6.

---------- Post added at 09:47 AM ---------- Previous post was at 08:47 AM ----------

Well....I just had a SOD. I guess everything I said in my last post was incorrect. I was so sure too that I had the problem solved.

Trying your batmax profile...

Couple of doubts...

Is min freq 702 or something is wrong ? what is the min freq in batmax profile ?

Max freq is 1134 right ?

Also now that conservative changes have been removed by hellsgod for touch boost...do you think hellsactive might be better ?
[Nexus 4 General] Voxxx:
Because Gplay permanent FC, I did not notice the bug shown in screenshot(no internal storage)..I installed Rom again and everything is normal.

[Nexus 4 General] hellsgod:
Its because conservative is back to the state it was on b73. The current kernels aren't stables, I'm trying to find the cause for some SODs.

[Nexus 4 General] bart.found:
For me b75 was absolutely stable!! Never had a freeze, a random reboot or a SOD... Should I revert to that version?
[Nexus 4 General] hellsgod:
I think its better for now, yes :)

[Nexus 4 General] eurochild:
SODs (at least for me) were caused from disabling the wake up and keep awake of google play services

and never happened again, i also read that others report the same so i'm sure that were not related to the kernel
[Nexus 4 General] gorilla p:
OK, this might be a good point to clarify a number of things, as a number of questions have been answered at this point and are being re-asked. I can simply refer them back to this post if asked again...

No, touchboost still works for conservative. 702 is likely the touchboost freq. This has been answered a bunch of times "Why does my minimum freq show xxxx?"

The BatMax profile sets the minimum freq at 94MHz, touch boost will be 702 or 801mhz.

If you're concerned about it...

1- lower Core0 boost to 94mhz and save

2- lower the minimum freq to 94MHz and save.

3- Go back and raise core0 boost back to 702-801 and save again.

You also likely have an option in Developer Options called "Show CPU Info", which will show an overlay on the top-right of each cores frequency. This will show what your CPU is really doing.

You will see it at 702-1024 when you touch the screen, them ramp down quickly once left alone.

In regard to the question of hellsactive being "better", you need to google the " Android Governors Explained" thread and do a little reading.

I've said this before. Hellsactive is good at doing what it is supposed to do, but it is an interactive-based governor which is made for performance and has a quick ramp-up/hairpin trigger.

Conservative is the opposite. It ramps up more slowly and lowers more quickly to avoid long durations at high freqs/battery drain.

Because of this Hellsactive is used in my performance profiles. Conservative is used in my battery profiles.

I have tested multiple governors with the same settings and battery life was significantly better with Conservative. I did this because others made claims that SmartMax and StockDemand were better for battery life, but that turned out to be untrue.

I hope this answers some questions

[Nexus 4 General] gorilla p:
There is no overclocking in this kernel. It appears that this CPU is capable of 1800MHz and GPU at 533MHz.

You can safely do 1.7GHz CPU and 487MHz GPU.

Yeah, with a cleaned up device (permissions, unnecessary autostarts and wakeup permissions disabled and unnecessary apps greenified)

This phone is sleeping like a baby on b78 with BatMax profile.

Battery life has been great.

I was having some weirs battery readings (random drops and occasionally increases).

I fully charged my phone and let it charge for a few hours, I used one of the battery calibration apps, used it and let it drain all the way down, then gave it another good full charge and it's been a lot better.
[Nexus 4 General] Selmak:
I'm now at 47 hours up time on build 78. Here are my current settings. I may try going back to one minimum core instead, but with 2 minimum I'm not getting any SODs. The other thing I guess I could try is setting the slider to not force one core when sleeping. So I could allow one core, but not force it.

Edit: image not showing, but you get the idea. Also min freq is at 594. I may try turning that down again as well.
[Nexus 4 General] underskyzx:
The cause of 99% of the SODs reported in this thread are:

1. ROM related

2. Bad Gapps package

3. Dirty installations

4. Too much underclock

5. Crazy settings (min. screen off 189 MHz i.e)

No SODs here since b63 or b65, it's been stable for so long I don't ever remember the last one.

Always using latest Purity clean install
[Nexus 4 General] gorilla p:
Can you show me the logs, screenshots or other data that you have that corroborates this? Its possible (ROM related), but I think it requires some more testing.

Just a quick double-check - hells core is compatible with 5.1.1, correct?

Just upgraded my N4 to 5.1.1 using NRT and lost hellscore.

[Nexus 4 General] salxtai:
Cheers for the quick reply ;)

I went ahead and downloaded the B78-L off box (running stock ROM, rooted), and attempted to install via NRT.

I'm getting an error via the phone's TWRP:

Now I'm 90% sure this is how I installed B73 last time, so not sure what's gone wrong - incidentally, I did run into this error when trying to go back to stock kernel to flash 5.1.1 earlier but decided it was a fluke and just got NRT to install the 5.1.1 factory image w/o wiping user data as I figured it would override the custom kernel anyways.

Not sure if this is the kernel file itself, or if I should hunt for the solution from the point of view of the NRT?

---------- Post added at 11:19 PM ---------- Previous post was at 10:56 PM ----------

Addit: Just tried flashing B78 using TWRP, and ran into a similar error. This time it says:

... I'm at a lost. NRT definitely updated my N4 to 5.1.1, successfully re-rooted it via N4 + installed TWRP in the same process, so not sure why I'm suddenly getting errors flashing zips via both custom recovery and NRT.

Could it be some bizarre kernel zip issue?

[Nexus 4 General] steviemch:
Are you using the latest version of TWRP (2.8.6.1)? I know version 2.8.6.0 had problems unzipping zip files leading to errors.

The problem could also be NRT, why not just flash the zip directly through recovery?

It's a TWRP issue. This has happened with a few different TWRP releases with the usb-otg error. I didn't have this error in 2.8.6.0
[Nexus 4 General] steviemch:

[Nexus 4 General] gorilla p:
No major changes. It has a toucuboost which should do that. If you're using conservative with touchboost (which you can adjust to whatever you want) and you're still having lag, you may want to check out the optimal battery life document on makostuff to clean things up.
[Nexus 4 General] salxtai:
I did try via recovery directly, got the same type of error e.g. unable to mount /sd-card/usb-otg.

As for TWRP, I'm using whichever version is automatically loaded up by NRT, which I've just confirmed is 2.8.6.1

Can also confirmed I've just tried changing from MTP to PTP, with no difference in outcome - same errors as above with both NRT and directly via TWRP.

What really confuses me is the fact that I got this error when trying to flash the stock kernel yesterday before installing 5.1.1, so the error was already there - possibly starting after I installed my custom kernel, but I don't undertand the error enough to see how a kernel could kill the usb-otg, let alone why the issue isn't resolved when the stock kernel got flashed over the top by 5.1.1
[Nexus 4 General] gorilla p:
I've seen the usb-otg error with almost everything I've flashed with TWRP 2.8.6.1 but it hasn't effected anything. This uwb-otg error has popped up before and is of no consequence.

That 2nd error however, I have not seen.

Try flashing TWRP 2.8.6.0 using flashify (play store) and see what that does.

You can get TWRP2860 from bit.ly/makostuff root&recovery folder.

Flashify is simple if you haven't used it before

Flash>Recovery image>choose a file>navigate to downloaded twrp2860 file and flash.
[Nexus 4 General] salxtai:
Just tried that, still with no success. Installed 2.8.6.0 from /makostuff with flashify, and confirmed it is running.

There is no mention of the usb-otg error, however I get the following now:

I also tried through Flashify and was told it was successful and to reboot now, but when I press "reboot now" it goes into TWRP and I can see the same error as above in the log.

Yeah, as I said, the usb-otg error was just a stupid TWRP bug, which didn't exist in 2.8.6.0.

The other error you're getting is something else that I haven't seen before.

Its not likely kernel related and likely isn't TWRP related either.

However google returned only one result for this error and the person had it 2mo ago

Is this happening when flashing other kernels?

If not, try downloading the file again, or try downloading it from another source/location like makostuff, to make sure you don't just have a bad file.

Just for comparison, I use ES file Explorer and when selecting properties, it shows the following file size.

[Nexus 4 General] salxtai:
It happened with the stock kernel I downloaded to flash over my original hellscore (B73) prior to starting the 5.1.1 upgrade.

However, I have no explanation on why this all happened but I went and re-downloaded b78 from Mako, this time directly into my phone rather than via the PC, and it's successfully installed via flashify!

I have no explanation, although I suspect it was a confusing combination of a bad file (original b78) and a buggy TWRP that got installed after I upgraded to 5.1.1, although that doesn't explain why my stock kernel failed to install at the very beginning before 5.1.1 was added....

Now I need to play around with b78 settings - seems my b73 settings are still remembered by HC kernel manager - can I just leave them at that, or should I follow the suggestions posted in this thread as to tweaking b78 specifically?
