What is the proper procedure of flashing this kernel?

I've been trying to flash this kernel since R8 or R9, never got the chance to boot up after flashed it via TWRP.

Thanks.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
You shouldn't have to do anything special to flash this kernel . The kernel should be installed without touching the ramdisk , I don't use any boot scripts for settings or anything so if it's not booting up for you I'm not sure what it could be.

I obviously flash a lot of kernels , I usually just fastboot flash the stock boot image ( which is redundant and unnecessary , but I just do it to make sure ) then fastboot flash my kernel , then fastboot BOOT twrp to flash root.

Beyond that I haven't had a kernel not boot for me that had previously worked . Meaning the only time my kernels don't work for me is when I mess something up. ( Mess something up building the kernel that is )

I guess it could be your phone not liking the overclocking freq , but the gpu freq isn't maxed out on boot , and sched governor should keep the CPU freq in check .

IDK what rom you are on , or what else you have loaded up , but only suggestion I have is to dirty flash your rom's system and boot images , and try to flash the kernel again. Have you tried flashing other custom kernels ? Do they boot ? If not I'd say it's something else.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] :
I just installed and everything is working fine easy to install thanks broski

working perfect in RR 8.1.0 edit, when I'm using the phone I have no problem, but when I put it to charge and I'm not using the phone begins to restart often a solution?
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] spr33:
Just wondering how much of a performance increase there is from the overclocks (both CPU and GPU) and if they trigger thermal throttling?
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
I would say it's a noticeable difference in benchmarks lol , and I do see an improvement in larger apps opening , some games run better for me .

I'm not sure about the thermal throttling , are you asking if it gets hotter faster ? A little but I haven't noticed anything extreme . I just use core control anyways. And I set the thermal throttle point pretty high . On my device.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] Mikkey81:
Seeing a crash on Duo in round r17. I'll pop back to 16 to double check it works there.

Edit... So it's video related as duo pops open. I'm not sure how far across video apps it goes but there is no true crash it just doesn't open. R16 doesn't have the same issues.

Thanks as always. Pimp status.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
Interesting .

Duo seems ok for me , video works , I made a video call through Facebook messenger app yesterday , worked ok . Same for recording video through camera app .

Maybe try wiping the apps cache , and force stopping it .

At any rate I'm sure I'll be pushing a new kernel anyways , just to update to Linux 3.18.95 and some other minor updates . But I would try to get duo to work with the newer kernels. It should work.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] Mikkey81:
No good call...

Before I sent that I tried on 2 roms. To ensure it wasnt a room issues.

I ran it and was able to connect vie Firehound with EX installed. I switched to 17 and lost it.

No worries. I didn't pull a log either so... It didn't happen. I was able to repeat the issue by just starting the app with 17 installed...

Quick question...These are flipping great. Are You running everything through scripts or do you have an app you use for quick edits on CPU etc... I can't find a clean app that will manage some of the quick changes. I don't know my scripts very well either. Just curious. Thank you as always.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
I use exkm for everything , I use the user settings tool to set fingerprint boost , zswap , etc. Basically everything can be reached through /sys/whatever , or proc/ whatever. You can set them manually from a command line with the "echo" command , or through a root file manager.

What quick changes were you not able to access via a kernel manager ?

I used to use synapse for my kernels , but just haven't set anything up for it. But there is a zip floating around xda called ukm , ultimate kernel manager. It is supposed to inject uci support into the ramdisk ( what synapse needs to work ) and have all the backend written for every device . I tried it on the pixel a couple months ago but couldn't get it to install properly automatically , I had to manually copy and set permissions for everything. But once it's setup , synapse is definitely the most complete kernel tuning solution imho
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] dnsh89:
I'm new to this.. can you guide me how to run these command line for zswap and fingerprint boost in Exkm.. :confused:
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] Mikkey81:
Nah just kicking over CPU tuning. I like to just go back and forth high to low through govenors to really learn where to push on each... like sched kicks a** on a high min CPU and standard stock max... and EX doesn't hold so I end up plugging it through scripts but if youve seen me around I have a crack flash addiction and flash a new rom everyday to every other day. Just seeing if there was an alternative solution. You have a decent cmd list or a good place to grab one....I can grab somewhere.

I'm sure other users could hang onto it too. Help a brother out? If not don't bother searching I'm already on the case to find a cleaner one than just the notes I have.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
So in EXKM , open the tools section , click the user settings tab .

In the bottom right of the screen that opened there should be a blue button with a + sign on it . Click it to add a new toggle .

That should bring up a browser window with different file paths .

For fingerprint boost the path is

sys/kernel/fp_boost/enabled

Then to enable it , simply input the value of 1 when it asks.

To turn off the value is 0

For zswap it is

sys/module/zswap/parameters/enabled

Then to enable it , simply input the value of y when it asks.

To turn off the value is n

Most of the tuneables can be set this way . Use a file manager to find the correct path , then enter into EXKM.

Most of the paths are in the Op too for reference .
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] dnsh89:
Thanks:good::laugh:
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
I see . Well I haven't tested the behavior of the scheduler based governor's in different kernel tuning apps. But the 1.9 GHz freq for the little cluster still gets used the proper way with those govs in EXKM , even if it actually resets the max to 1.5. that's the way it's supposed to work. I use real time freq monitoring and it definitely hits 1.9 when needed.

EXKM is seriously complete imho. It has just about everything we need.

I have been thinking about writing out a script to set the kernel how I set it , but TBH I doubt I'll ever get around to it , I'd rather let people set the kernel how they want it . And if you have to learn a few things to do it, all the better [emoji6]
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] spr33:
I attempted to flash the kernel yesterday but it wasn't fully successful.

I reflashed the February OTA, booted into TWRP (fastboot boot TWRP and not an installed TWRP), flashed Magisk (tried multiple versions) then your kernel. What happened was Magisk didn't show as installed and the phone would basically go to a black screen after x amount of time and would not boot again unless I held the power button for 20 seconds.

Not had this issue with any other kernel, just wondering if I'm doing something wrong?
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
No , its most likely because your phone's CPU can't handle the highest overclock frequency , so you can set the max CPU freq a bit lower ,or if your brave you can try raising the voltages globally by +25mv.

The first option is easiest and safest , IDK what your comfort level with kernel tweaking is .
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] spr33:
Ah, I didn't realise the over clock freqs were the standard values - back in the days when I was heavily into OC'ing, default values were stock with the option to OC for 'advanced' users. Maybe you could do the same to avoid similar things happening to other users?
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] TeChNoC4AzY:
This kernel is nice but it seems the CPU just has a mind of its own I am using ex kernel manager and when I set the CPU frequencies the way I want they always lower or raise themselves and I cannot edit them for some time I set the throttling temperature up a little bit and wanted to do a few benchmarks but the CPU just kept lowering itself constantly one time getting as low as 300 megahertz on all Cores staying there for a good minute or two I just want some kind of profile for performance when I am benchmarking to get the most out of it and something for gaming as well but the biggest thing here is how can I control the CPU the way I want do you have the throttling temperature locked in the kernel itself or can that even be edited

Also is quick charging enabled with this kernel?
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
Use any governor besides sched or schedutil , they use the max freq of the little cores different than other govs . If you use say interactive on the little cores , the max freq will not change .

The 1.9 freq is a boosting freq , meant to be a helper freq , not the max freq . But using a non sched governor will use the 1.9 as an actual max .

Yes this has fast charging enabled as well .
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] Gordietm:
It was mentioned here once before that enabling zram and uksm is overkill. They are both enabled you default. Should I leave it as is or disable uksm. What impact would that have? Right now, everything seems to be running well.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
There should be little impact running both . I use zram so I just turn off uksm , but I have had both running for days without noticing lol . While both are on, uksm reports around 8mb of memory saving. Without zram on, that number doubles.

So yeah , go ahead and kill one of them , but if you don't , nothing bad will/shouldn't happen lol .
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] Gordietm:
I'm going to try it with just uksm enabled for a bit and then with just zram enabled and see if I notice any difference at all.

This might be a stupid question, but if there is any noticeable difference, what would it be?
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
Honestly , real-world you probably won't notice any difference .

It's mainly a difference in how information is accessed and stored . You should see a difference in available ram with zram on .

Really both are unnecessary , the device has enough ram to not need the help , but i don't think it hurts any . With a device like the Galaxy Nexus that has a gig of ram and thats it , even less because of the carveout reserved for the camera on that device. So we had 750mb of useable ram . Zram , zswap , etc all help it that situation.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] Alcolawl:
Getting pretty frequency random reboots. Seems to happen most often when opening Snapchat and trying to bring Google Keyboard up to respond. Sometimes it'll reboot with the screen off and it just sitting on my desk. Whenever the reboot happens when I'm actually using the phone, it seems to nuke all of the cached data of the app I was using at the time and revokes notification access to my Samsung Gear Fit app. Very weird. I'll attempt to grab a kmsg when I get home from work.

Running Pixel Dust ROM R2, and R18 of this kernel. No special settings, all overclocks disabled. Schedutil CPU governor for both clusters, Deadline I/O scheduler.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
Op updated to R19

- patched up to linux 3.18.98

- I added a non-overclocked version to the Op . Same kernel as the OC version otherwise

- other changes can be found in my github

happy flashing :good:

You're a saint

The low binned Marlins will surely be grateful. ?
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
I've been called a lot of things , but that's a first lmao .
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] ChongoDroid:
Lmao well I call you a saint because I had been wanting to test the battery life of a non OC version of this kernel because I think using gpu boost to make up for lower clock CPU could be a good trade off for light gaming/UI frame rate.

So it's nice to have new toys to play with.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] ChongoDroid:
Is anyone running r19 non OC and if so, what rom are you on
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] Gordietm:
I also just recently got the black screen of death and couldn't do anything with the phone. Had to reboot and the same thing happened again. Im off this kernel for now. I used it for quite awhile and liked it.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] ChongoDroid:
It's just r19, the logs have been submitted and we all need to patiently wait for a fix. Roll back to r18 for now.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
R19 is no go

DO NOT USE

I am at work now but will fix later tonight

sorry for the derp
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] bsmitty83:
OK sorry for the bad kernel . I had no idea until my phone also experienced it . I ran the kernel for well over 24hrs before I watched it freeze then reboot then freeze on the lockscreen repeat and repeat .

It only happened when i turned bluetooth on . it was an immediate lock-up.

Never had that type of hard lock on any of my builds. not even once .

So for now I reset my branches back to R18 and re-applied the Linux update patches only . I haven't had any issues so far with the new build so it should be good to go.

Also too I have had instances of a know good kernel not booting up on first boot . just hangs on the google screen . So when that happens I can solve it by wiping the dalvik . IDK why that seems to work sometimes .

Anyways sorry for messing up your phones :( Hopefully it didnt break your phone at work like mine did and be stuck without for some hrs lol. (I called it NSFW for a reason .......)

Give it a shot . Hopefully it's back to good for everyone and let me know. I'm specifically after any hard locks that wont allow the phone to boot once it comes back on .

I am using sweep2sleep on the latest 19.1 non-oc version, and I found that instead of turning off the display, the action is just opening the power menu. Is anyone else experiencing this?

Yep I can confirm that.

Edit: double tap to wake works as does sweep to wake.
[Samsung Galaxy S7 Questions and Answers] Octanee:
Hey guys, so last winter I had no issues, snowboarding and taking the phone out, it was cold but battery was good. I noticed the past month or 2, now I noticed when battery drops to about 40% it drops fast! And when it dies if I plug it in for a short time it'll bump up to say 30% fast and discharge slower. I ran the battery discharge app, it drained down fast to about 2% then slowed, stayed at 1% for about 18 mins in the app before the phone finally shut off... , when it gets even a bit. Cold, say i left it in a 5 degrees celcuius location for 15 mins, it'll die. I thought huh? Plug it in for 5 mins and bam 68% percent. Today I was out snowmobiling, about - 2c or about 26f? The first half the ride it was ok, airplane mode on it had 85%, then get back to the vehicle and look at it, it was off, try and turn it on, it showed 0% and shut off. Let warm up and bam back to 80%....

What's going on? I think a battery mis calibration? It's bizarre and I've Googled but havent found a fix. Thanks!
[Samsung Galaxy S7 Questions and Answers] JeffDC:
Well, I'm thinking a few things:

1. Batteries hate the cold, and can be very sensitive to temp changes/certain temps where they really drop off efficiency. Age and cold can certainly add to their stressed unreliability.

2. If your battery is doing well in more normal temps, drops to say 40%, and then drops fast, followed by a recharge to 30%,where it discharges slower, maybe because the charging heated it a bit... ? So it's performing a tad better ?

3. Seems less possible that there is a short, but could be a temp sensitive short. I have seen those in electronics and cars, though the initial description has the feel of a battery going south.

If it remains stable to 40% and higher, and either the 40% lower threshold or temp get's it, perhaps changing out the battery would be a safe bet.
[Samsung Galaxy S7 Questions and Answers] Octanee:
Thanks for the reply. I got reading a theory that as the battery ages, internal resistance goes up and when it gets cold it really shows, but who knows. My. Best bet I think is just to replace the battery.

Hi guys, a friend if mine wants to exchange my G930F for his Nexus 6P. What You think?
[Samsung Galaxy S7 Questions and Answers] Beanvee7:
S7

Both the Exynos and Snapdragon SoC's and GPU's for the S7 are better than the Nexus 6P. The 6P also has the SoC known for bootlooping.

If you have the Exynos variant it's also got ROM support like the 6P.
[Samsung Galaxy S7 Edge Questions and Answers] HD7WP7-User:
Hi, my Samsung S7 Edge, SM-G935W8, use to get monthly updates up until a few months ago. It's a Rogers, Canadian carrier, phone but it' unlocked and I use it with Vigrin Mobile Canada. I use to plug it into my computer and use Samsung Switch to update, and occasionally I would get a OTA update but nothing since Aug. Is there something I can do to force a new update? I don't want to root the phone or go to a custom ROM as I use my phone for work, have it encrypted, use Android Pay and RBC Wallet, Secure Folder, and other Samsung apps that I would prefer to stay unaffected.
[Samsung Galaxy S7 Edge Questions and Answers] HD7WP7-User:

I suggest you root your phone and install one of the s8 or n8 ported ROMs, which include the newest security patches..
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
I know i can root and install custom roms with latest security patches, but the problem is that samsung sucks when it comes to updates and especially its way of ignoring some regions/countries totally while providing to some, it really needs to change its priorities.
[Samsung Galaxy S7 Edge Questions and Answers] nexidus:
You can search for listings with official firmware released by Samsung for your device model.

For example (am a new user so link restricted):

www sammobile com/firmwares/galaxy-s7-edge/SM-G935W8

There are guides on XDA for flashing official firmware. The usual caveats being:

1. Potential loss of data

2. If unbranded then technologies like VoLTE / 4G / RCS may not be supported

3. Scary if it's your first time. Be gentle, take your time, and read the guide ;)

You can flash with Odin in Download mode without voiding warranty because it's signed by Samsung.

Since it's for work you probably have a backup, but if you want to retain your data you can flash your HOME_CSC instead.

Have you contacted your carrier for more info?

Is your device being controlled with MDM policies by your business/enterprise, i.e. managed inhouse?

It seems you use it in public venues so hopefully you are using a VPN or similar for your business.

Good luck!

[Google Pixel 2 XL Questions & Answers] bretrick30:
I have noticed my battery life on my watch has been really bad since getting my Pixel 2 XL. I previously had the regular Pixel. I have everything set up the same but I did notice today that in the drop down, there is a Bluetooth icon and sync arrows that flash often so I'm thinking the Bluetooth is syncing a lot and causing my battery issues. I have added a screen shot of what I am talking with the link below, I was unable to attach a photo for some reason...

https://drive.google.com/file/d/1A1Tt5j-J1TAYuUSlcWYU1mSlZJBHB7QP4Q/view?usp=drivesdk
