I've tried both on my 002 EVO and even though it goes without saying I will say it anyways - Netarchy 4.1.9.1 FTW! Rock stable and great battery life for me.
[EVO 4G Android Development] scooter185:
i've ran both and decided to stick with 4.1.9.1, best battery life i've ever had.
[EVO 4G Android Development] Biofall:
Wait.. So I was giving the correct info, right?
[EVO 4G Android Development] hungry ghandi:
This kernel kicks ass. Using it with Fresh 3.2, UC'd to 800MHz, and it just sips battery. And it's stable on my phone, which I can't say for King's. Thanks Netarchy!
[EVO 4G Android Development] Scottie2H:
fresh 3.2 w/ 1.4.9.1 bfs. liking this so far! stable and quick. quadrant benchmark at 998mhz was 1449
[EVO 4G Android Development] bigupurself7:
I read in one of the boards that HAVS and SetCPU don't work well together. Is this true? Im using it now and it works fine, but just curious what other people think.
[EVO 4G Android Development] eniamg02:
Always used both and everything works fine.think for better battery its recommended not to use.
[EVO 4G Android Development] EVOme:
OK, so I just flashed 4.1.9.....dear God I hope this works better than the others I have been using.
[EVO 4G Android Development] TorxT3D:
netarchy livess!!!!

dude, we thought you got ambushed by naked mecha bunnies!
[EVO 4G Android Development] EVOme:
OMG!!! I flashed 4.1.9 and my phone sat on 100% for like 30 mins. even with a missed vibrate call and two text messages. Before when I was on the BS kernels and even Kingz 9, as soon as I unplugged my phone it would drop to 90% with an hour w/ NO use.

I have been flashing more kernels then I can even tell you to find one that made a difference....This one DID!!! Thanks more than I can say, Netarchy!!

Edit: I turned all my overclock profiles off and on main I moved the governor to 'Conservative' instead of 'on demand' and it's overclocked to 1228mhz.
[EVO 4G Android Development] Biofall:
Aw. :( Coming from King back to net, and for the first time in my flashing career, got bootlooping when I tried to flash 4.1.9.1 bfs (or just not the other one). I did wipe what I was supposed to, repeatedly. Gonna try the cfs now

EDIT: Cfs bootlooped too.. and 4.1.8... Crap..
[EVO 4G Android Development] 95z-cross-eyed:
I feel your pain both 4.1.9.1 bootlooped om me. Running 4.1.8 and it runs fine. Something different between the 2 my phone does not like.
[EVO 4G Android Development] 95z-cross-eyed:
Fixed message
[EVO 4G Android Development] jelive:
Thankfully I didn't have this issue going from King 9 bfs to 4.1.9.1 bfs this time...by chance did you use the wrong one for your ROM since there are generic/Fresh/DC ones...I did that after I changed over to Fresh ROM without realizing it and fun fun !! :o

Jim
[EVO 4G Android Development] onyx00:
I went from King #8 BFS to Netarchy 4.1.9.1 HAVS and I disabled SetCPU and all, and the performance was pretty bad compared to King #8 w/ SetCPU. The screens were lagging a lot, etc. I cleared cache, but since I have Clockwork Mod I am not able to properly clear Dalvik, however, I have a hard time believing that would lead to the performance issues I saw.

At any rate, I'm going to stick with King #8 for awhile since it is liquid smooth for me and no battery issues.
[EVO 4G Android Development] unknown_owner:
Does this kernel enable wireless N?

edited: Nevermind found my answer. The phone's wireless N only works on the 2.4ghz freq, not the 5ghz. I also had to change the 2.4ghz to mixed G/N from what it was set to just allow G. Now when my phone is near the router, the router says the rate is 135 Mbps and the phone says 65 Mbps. Download speed hit 17.8 Mbps and upload hit 7.5
[EVO 4G Android Development] cruecu:
What's been the concensus on using Setcpu with the newest kernel with HAVS? I've been reading all day and last night, but I couldn't get a clear judgement one way or the other. Mine is flying with fresh rom and 4.1.9.1 cfs. I've uninstalled setcpu since I've been running this kernel. Is it just profiles in setcpu that conflict with HAVS or constant UNDERclocking from the program in general? I'll keep it off if the overall feeling is that it doesn't help.
[EVO 4G Android Development] Biofall:
Yeah that's what I did. I thought after wiping cache and dalvik cache and then flashing a new kernel it might fix the bootloops, but I was wrong. Finally I wiped everything and started over, with net running smoothly
[EVO 4G Android Development] Roadk1ng:
I have a quick question. Did clokwork fix this issue?

Clockwork Mod is reportedly not wiping correctly (ie; if you try to wipe cache/dalvik-cache/data/etc it's not actually doing it, or not doing it right)
[EVO 4G Android Development] ricsim78:
Clockwork works just fine. People thought it did not clear the Davlik because it never reports that it does. You hit it and it does not seem to do anything. But people checked the Davlik after using Clockwork to wipe it and indeed it does clear the Davlik. I actually am using Clockwork and it seems to work better than Amon does for certain ROMs, plus I can use ROM Manager from the market.

This has been discussed in detail for a while. Both of the recoveries work just fine. Use which your prefer.
[EVO 4G Android Development] bigkmoney:
I just wanna say how impressed I am with this kernel (4.1.9.1). I am running it with baked snack 1.7 and have been getting some great battery life and solid performance. My phone has been unplugged for 17 hours and I still have 70% battery left with slightly less than normal usage.
[EVO 4G Android Development] Roadk1ng:
I'm very impressed with this kernel (4.1.9.1). Great job love the new speed.:eek:
[EVO 4G Android Development] nemesys504:
Update

Any update for a new kernel?
[EVO 4G Android Development] jhuff83:
Does the newest 4.1.9.1 not work with software 3.28? I flashed OMJ'S rom and tried to flash this afterwards and all I get are bootloops. I had no problems with this running on 3.26.
[EVO 4G Android Development] strongsteve:
+1

Only get bootloops with these kernals after moving over to the 3.28
[EVO 4G Android Development] Compusmurf:
Go back some pages and re-read the answer. It was posted quite a few times, even by NetArchy himself....
[EVO 4G Android Development] S4Rs:
Using setCPU

I have to say I was hesitant installing an Kernal other then the stock one on my stock Evo Rom with Root, but this was so easy and adds so much polish to my phone. The faster fps and better responsiveness overall are very noticeable. Thank you. I am using 4.1.9.1 CFS. I used clockworkmod to flash too and there was no problems. It aggravates me that I have to root my phone and void its warranty to get it to work the way it should from the factory. A couple of dudes in their spare time make a better kernal than a team of engineers with 6 figure budgets.

Just a quick question, are people with this kernal using setcpu and profiles? I am using a basic profile that lowers the max cpu to 700Mhz at 50% battery left and 500Mhz with 25% left & when the screen is off. Min cpu is always 125Mhz (or whatever the lowest setting is) and everything is set to conservative. Pretty good results too. I left auto-brightness on yesterday though (which is usually too bright all the time when indoors) and was at 50% battery left at the end of the day, with some light browsing/downloads/4g.

I would love to hear recommendations from others though.
[EVO 4G Android Development] scottspa74:
@jhuff83 and strongsteve

Weird, I don't have any problems with these kernels on 3.28 ROMs (namely, right now I'm runnin virus" badass ROM). Haven't had any issues. You do have to use the right kernel for your ROM, though. For example, fresh compatible, or dc compatible, etc.

I'm gonna go have a look what compusmurf was referring to, but I haven't had any issues.

BTW, thanks netarchy.
[EVO 4G Android Development] Compusmurf:
Quick reply.....

In 3.28 unreleased OTA, the kernels were changed some, and the OTA is NOT available yet. Nobody even knows if it's final yet. If you install this over that, you may or may not have success. Netarchy will update to the newer kernel when/if the OFFICIAL ota comes out and he gets the source code.

If you install this and it works, great, but you may run into issues or roll back any fixes that HTC is including in the new kernel.

Without the source code, nobody knows what you are replacing.

YMMV, but make damn sure your backups are current....
[EVO 4G Android Development] evokinevo:
I'm a relative noob. Been running Baked Snack 1.7 w/sooth sense on my Evo for the last few days. Wanted to try 4.1.9.1 to improve battery life, but after flashing it went into an infinite boot loop. I'm restoring the previous nandroid right now. Any idea what I might have done wrong? I used Rom Manager to flash the kernel...

Thanks!
[EVO 4G Android Development] chuckyholmes69:
this kernel is sweet. before, i just rooted/nand unlock and used the stock rom as is only just using some apps. battery life sucked. then i added kingclicks #9 which got me 11 straight hours of pretty heavy use with about 17% left. battery life does start dropping much quicker with kingclicks #9. after a few days experienced some lag, some force closed, and mic to search/text didnt seem to work as well. so i loaded up fresh rom, battery life sucked. seems like i unplug it and its at 90% already. so i tried this kernel with fresh and right off the bat i noticed the difference. i unplugged and took 22 min before it even went below 100% after 3 hours at 83 % all this with heavy use. probably too haste for an accurate report, but so far am very impressed with the battery life.
[EVO 4G Android Development] xlGmanlx:
is it me or does the kernel arm's race seem all but dead and that there has been a big slow down in releases? My hope is that there are some major things coming out that will beat the breaks off of what we already got
[EVO 4G Android Development] Brian75:
Perhaps this was already answered or someone had experienced a similar problem in regards to the latest 4.1.9.1 BFS kernel. I've read and searched through plenty of pages and everyone's problems naturally vary differently, so I decided to post mine.

I jumped from the stock kernel to this kernel and battery life seemed to be great!

Day 1 - I was unplugged for almost 24 hours with about 30% left the first day. I had pretty low usage though. A few phone calls (total of about 1.5 hours) and about 50 texts. I didn't have any of my e-mails setup yet though (I set that up in the middle of the day).

Day 2 - (My 3 e-mail accounts are now setup with peak time sync every 10 mins) I've used the phone for about 2 hours w/ BT and once again about 50 texts. I'm currently at a little over 9 hours unplugged and I'm down to only 20% left. Looking at the battery usage it shows as follows:

Android system - 92% (is this because of the e-mails?)

Voice Calls - 4%

Cell Standby - 2%

Phone Idle - 2%

A couple of questions:

1) Before I flashed this kernel, I did wipe cache and davlik via Clockwork. I did not wipe battery stats though. Could that have an affect?

2) Naturally the biggest variable from Day 1 to Day 2 is e-mail setup. Would e-mail synching that often drain the battery.

My EVO is pretty stock otherwise - stock rom from running Unrevoked 3.21. No other special apps (e.g. setCPU, etc.)

Loved this kernel but hope I could get over this hump.
[EVO 4G Android Development] rezn:
I do much more reading that I do writing on here, but I have to say since using the 4.1.9.1 CFS kernal I have had nothing but great results. I originally flashed with Clockwork recovery and had some residual issues. I decided it would be wise to listen to the OP and try it with AMON recovery and now my phone is where it should have been when I bought it.
[EVO 4G Android Development] Compusmurf:
And this is precisely why doing the 3.28 with this kernel wasn't great. the 3.28 was a test build........

[EVO 4G Android Development] JavaIV:
I'll wait for HAVS to be considered stable. Downloading 4.1.8 now. Love NetArchy's stuff! Thanks for all the hard work.

EDIT - Ok I downloaded and installed and it works great...no crashes, except when I overclock in setcpu. I can overclock to 1190mHz but then anything above that crashes the phone and forces a reboot (either freezing and making me pull the battery or just rebooting itself). Any ideas? I am on DC3.5.
[EVO 4G Android Development] skantman69:
Can someone explain to me why I can't download the files using the android mobile app. This seems to be the only thread I can't click on the download links.
[EVO 4G Android Development] EVOme:
My phone has a mind of its own..One day it stays in the 90s for hours and other days it drains quickly through the 90s. Even still, the 4.1.9 kernel is the best one I have used to date and I don't see me ever changing.
[EVO 4G Android Development] nemesys504:
Why do I feel this project has been abandoned? Hasn't been updated for awhile.
[EVO 4G Android Development] jelive:
Pretty common aggravation. I've tried several of the recommended battery methods.

Know it sounds funny but I've gotten more consistent battery drainage day to day doing this: charging till green light, unplug for a few minutes...then plug back in...note that some days it charges back to green quickly and others it takes awhile.

Source of version history, please. Sprint's own changelog looks like this:

http://support.sprint.com/support/a...e-wh164052-20100527-115429?&INTNAV=SU:DP:HDIA

No mention of FPS cap.
[EVO 4G Android Development] netarchy:
Not abandoned, I can assure you.
[EVO 4G Android Development] BrianBusby2038:
Screw him Net,you've been doing outstanding work and it's much appreciated.
[EVO 4G Android Development] netarchy:
I can understand where the thought might have come from though, it has been pretty quiet as I've been a bit busy.

Based on feedback I've received so far it would appear that I probably need to put out a couple HAVS builds targeted at different voltage levels for people whose phones are a bit unstable with the current default minimum.

Then of course there's the matter of bfs 330 which is actually in my github already, I just haven't had a chance to put up some builds for people to test on.

Plus now with the new ota around the corner and inevitable newer kernel sources from htc (with apparently magical battery code) that will come after that, the timing of everything is going to be interesting.
[EVO 4G Android Development] kegacide:
wow this is my first time flashing a kernel and experiencing the increase in FPS... amazing...

things seem so smooth its ridiculous... so far so good with this kernel, gonna keep an eye on the battery life throughout tomorrow
[EVO 4G Android Development] noregretzzzz:

Hasn't been confirmed.

[EVO 4G Android Development] scottspa74:
Isn't it only the kernel source that has not been released? Seens as how we do already have 3.28 ROMs on xda now? I've been using the 3.28 ROMs, and tried pretty much every kernel with them and really haven't seen any issues. The kernel source hasn't been released yet, so the kernel building is stagnant for now. The 3.28 ROMs are everywhere.
[EVO 4G Android Development] Compusmurf:
3.28 is ancient history now. 3.29 is official and probably get sources soon. :)
[EVO 4G Android Development] EVOme:
Hey, man....where you been?
[EVO 4G Android Development] Richkid:
Sure is; OMJ released his v3.3 this morning based off of 3.29... Must say, it's definitely playing nice with 4.1.9 BFS.
[EVO 4G Android Development] mrwilly:
using your 4.1.9.1 CFS kernel with the new OTA and it definitely runs better with your kernel compared to the new HTC kernel
[EVO 4G Android Development] d0cx:
i'm looking forward to a new version of this kernel based on the official one from 3.29.651.5 and i'm very insterested to see how htc uncapped the fps versus how the devs here did it. it's VERY interesting.
[EVO 4G Android Development] ticklemepinks:
Why is everyone flashing the custom kernels on top of this, i thought the update change uncapped the fps and add hdmi back into the fone, and helping with battery life too... why are you guys still flashing the custom kernels??? don't bash me plz lol
[EVO 4G Android Development] ___DJK___:
Net, just wanted to say I've been using your Kernals with every custom ROM I've run and they are awesome. Ive tested others, but none are as stable or as fast.

Looking forward to seeing what you can do with the new Kernals!

Thanks!
[EVO 4G Android Development] mjohnson4580:
Hey netarchy with the new ota have you successfully moved the dalvick to cache and if so could you let me now how u did please
[EVO 4G Android Development] :
With the new OTA, I can't wait to see a nice and shiny new build of this marvelous kernel!
[EVO 4G Android Development] netarchy:
Well, the HTC kernel:

1. Doesn't allow you to overclock/underclock/overvolt/undervolt - A big issue for a lot of people.

2. Doesn't allow you to change/tweak the cpu governor (Locked on perflock)

3. Didn't "add hdmi back in" because hdmi already worked with my kernel (and other custom kernels) and has worked for a very long time in conjunction with our fps fix. I don't know where the idea that hdmi was somehow still broken came from. The HDMI not working with uncapped fps issue was fixed before the froyo update ever hit the evo, when we were still using 2.6.29 based kernels.

In fact, given that htc's fps fix appears to be not based in the radio, many of us suspect that htc may have simply adopted the fixes we've been using here for some time (as they haven't released updated sources for the newer kernel used in the OTA at the time I'm writing this, the suspicion can't be confirmed or refuted).

About the only thing the HTC kernel does have that isn't in the custom is apparently some magic battery changes (at least in the leaked 3.28 build, it's unknown if these same changes are in the official 3.29 ota kernel) that will inevitably find their way into the custom kernels once the updated source code is released by HTC for us to dig into.

That said, the battery life on many custom kernels is pretty decent as it is with stuff like undervolting and HAVS (or as several people have started dubbing my version, nHAVS), plus the framerates are more stable (seriously, have you heard some of the benchmarks on the HTC fixed kernel? 53 fps with a 10point stdev?).
[EVO 4G Android Development] MSmith1:
Netarchy for president!
[EVO 4G Android Development] d0cx:
and this is why i use your kernel. :)
[EVO 4G Android Development] asafegous:
Where is the link for the kernel?
[EVO 4G Android Development] novanosis85:
Dude the links don't show up on tapatalk or xda app.

you need to go to a browser.
[EVO 4G Android Development] netarchy:
Right. I think it's fairly safe to mark 4.1.9.1 as stable at this point, new beta build soon!

And if you're curious, yes, it works on 3.29.651.5
[EVO 4G Android Development] frifox:
Any differences between the previous beta and current stable 4.1.9.1?
[EVO 4G Android Development] netarchy:
No, it's just been in use long enough to safely say it's workin well ;D
[EVO 4G Android Development] FastJoe78:
Try calibrating your battery...basically you need to charge it with the phone off, wait for the green LED, turn on phone while unplugged, then after its completely booted plug back in and charge while on, wait for green LED. repeat this process until the LED is green immediately after plugging it in. Should be green regardless of whether its on or off. If you have less than 5 to 10 secs before the switch from Orange to green you are calibrated. Do this once every month or so after you run the battery down past 15%...FYI you should reframe from charging your battery if its above 30% on a constant basis as this will uncalibrate it. If you search google you will find a very well written post describing this process in much detail.
[EVO 4G Android Development] :
ive been using the 4.1.9.1 on fresh 3.2 for about a week and a half -

GREAT BATTERY LIFE! as this wasnt the case the first few days .. and i didnt calibrate like above- i cant seem to let my phone get down to 15% before i put it on a charge - i USE my phone so letting it sit there with 15% and waiting till it hit atleast 80% so i can take it off the charger with good battery is jut too long for me

i would post a screeny - but i rebooted my phone to install a theme-

off charger 945pm .. browsed a bit sent out few text - sleep at 1045 up at 7am off charger - 88% left on the phone using setcpu to sleep at 245min ... its now 9am and i browsed facebook to check messages and sent out 10 texts this morning ... now at 71%

GREATTTTTTTTTT GREAT !! BETTER THEN .8 ... donation headed your way!!!
[EVO 4G Android Development] EVOme:
Got your 4.1.9 running on new rom I just flashed...loving it.
[EVO 4G Android Development] Jayr00:
Netarchy and Toast, you guys are definitely some of the greatest devs on here... using fresh 3.3 and your 4.1.9.1 bfs oc'd to 1113 and battery / performance during games is awesome! Thanks a ton for your contributions to the Android community.
[EVO 4G Android Development] netarchy:
I'm a little behind schedule in that I wanted to get a build out in beta over the weekend, but since I don't feel that it's quite ready for public testing yet, here's a teaser of what's coming up soon(tm)

Teaser
[EVO 4G Android Development] smw6180:
...wow! Now I can't wait! :)
[EVO 4G Android Development] xhazyx:
i saw that king had a beta with the .34 kernel... but i read that it had a lot of issues, basically making it unusable

if u get yours to work fine, at least with no major issues, u might bring me back to sense :D

btw i use 4.1.9.1 everytime i feel nostalgic and flash a sense rom lol
[EVO 4G Android Development] nemesys504:
Loving it. Keep up the great work.
[EVO 4G Android Development] Djay45:
Thanks for all the work!

BTW anyone know where I can get a flashable 3.29 kernel? Always good to have the stock kernel just in case something goes wrong.

PS. Donation sent. Thanks again! Confirmation number: 2KN96120EK3759625
[EVO 4G Android Development] five40:
I've tried flashing 4.1.9.1 Fresh compatible HAVS & CFS i'm running Fresh 3301.

My Evo hangs at the 1st splash screen and fails to boot and I have to do a Nand restore to get my Evo working again.

Any suggestions?
[EVO 4G Android Development] barleysoda:
You have to wipe cache & dalvik cache. Which recovery are you using? I couldnt do it with Clockworkmod so I switched to amon-RA and then wiped the caches twice and flashed 4.1.9.1 BFS Fresh over Fresh 3.3.1

Everything is working for me so far.
[EVO 4G Android Development] EVOme:
4.1.9 did not work on Fresh 3.3 for me either. I ended up going back to BS 1.7 cause that kernel proved to give best batt life of any I tried.
[EVO 4G Android Development] :
no problems here on cfs or bfs 4.1.9.1
[EVO 4G Android Development] EVOme:
I did a factory wipe twice. First time I was not sure what caused my problem. Then I wiped again and all was good. I flashed that kernel again and my problem surfaced again.

What I was seeing was....After I installed Launcher Pro, widget locker and home switcher...(I added these before 4.1.9) I could go into Home switcher and choose LP, Sense or WL as default home. Once I flashed 4.1.9, It removed the Sense option from that list. Therefore, I had to use LP.

I wiped again...same result....went back to BS 1.7
[EVO 4G Android Development] :
i always just do everything from the start before i add anything - i will install rom > kernel > then theme> then everything else .. currently using home switcher and launcher pro ...
[EVO 4G Android Development] five40:
I forgot to mention but I did wipe both the cache & davlik cache.

I did not however do a full data wipe.

Is is necessary to do a full wipe?

I never had to b4 flashing other kernels.
