As instructed, you need to do some reading. In my last post I gave you instructions on how to add kernel.

Help yourself first, then others will be more than happy to assist.
[AT&T Samsung Galaxy Note I717] delawaredrew:
I'll give you some slack 'cause I am still close enough to my first flash that I remember being full of questions, but at least read the OP and most recent pages in your ROM thread. You should skim through it all ideally but some are 100+ pages so....

Kernel switching in general does not require any ROM action, there are likely cases that it might be useful but I've never had a problem. You will need to ensure that the kernel is matched to your ROM; KitKat or Jellybean or whatever. I usually do it as I flash a ROM but I have gone back and installed a kernel on a running ROM plenty of times; Uber for instance was released after I had BeanStalk up and running, it is a good kernel so I switched to that.

As a more general point the Note is hard to brick, as long as you don't somehow mess up the recovery (CWM or TWRP) you are just a quick restore away from back to normal. Use the backup function in your recovery, it is your friend and savior. Keep a copy of the back-up on your PC (or Mac) and you will usually be golden.
[AT&T Samsung Galaxy Note I717] jayinc11:
If you are on BS Rom you should know that all you need to to know is on the OP post-the rom and the patch. The latter contains about 5 different kernels which you can switch betw. to your hearts content. The patch is n00bie proof to make your switches. Really hit BS OP.

He uses aroma installer, so when you flash it (personally, I did it with CWM) you don't need to wipe cache/dalvik nor wipe phone, he mentons this on patch's thread while answering questions I believe. The screenshots show you some differences between the kernels he has available, either CM, Uber or PAC.

Personally, I'm using PAC since for me it seemed to work better with the Xposed's Netflix workaround, whereas it didn't work that well with Uber.

Also, the patch provides fixes, for camera, screen flicker and such.. Give it a try, and you'll definitely love your phone more!
[Sprint HTC One (M8)] Varekai:
I have been with sprint for 8 years now. Just got the M8 for the new spark network that according to sprints coverage map, I was fully covered in. We'll, that's not the case. Been having a lot of problems, mainly if I drop to 3g, I actually have no data and no phone calls and can't send texts . I have to wait until I'm in an area that I think may have spark, and reboot my phone. Then I get a flood of text messages and voice mails. This has been going on 3 days now. Apparently this is a mass problem that could be a while to fix. I still have ten days to return it and reverse my contract. Sprint is so bad that if I'm somewhere I don't know where I'm at and try to pull up a route on maps, it will fail to pull anything up, or search for a route until it says no connection, even with 4 bars. It's hard for me to leave since I've been with them for 8 years, but I'm really getting tired of it. Would like to know of anyone else is considering this, or may have left Verizon for sprint and why.
[Sprint HTC One (M8)] hazmad:
I've been with Sprint a while too. Just LTE in my area, works great though. I'll see whenever spark comes to my area. Have you talked to sprint about this problem? Possibly a defective phone or your tower's messed up. Do you have the same issues on CDMA only mode?
[Sprint HTC One (M8)] mswlogo:
Not sure it's possible but I wonder if loading the right PRL might disable Spark. Or there is a way to shut it off in the phone settings.

LTE is still up and down for me so I leave my phone on CDMA 99% of the tie for stability.

Most places that I need speed I have WIFI.

LTE just isn't there yet.

I'm on hairy edge at home and hairy edge at work (both places I don't need it).

Even when I'm in strong LTE areas if you hit a 3G pocket the phone behaves badly.

Have not had it long enough to know if it's better or worse than HTC One M7.

But I switched it to CDMA.

I just loaded PRL 56018. So it roams on VWZ (3G only).
[Sprint HTC One (M8)] MassStash:

I had to switch my phone for the same reason you just stated. I don't have these issues anymore.
[Sprint HTC One (M8)] Sim-X:
I have had sprint over 10 years now. Only reason I stay is I'm on Sero Premium. The network is absolutely horrible in my area. Dropped calls, week signal, 1X/3G/4G no data. I'm sticking it out for Spark & hoping 800 LTE will fix the coverage issues. The m8 has had better signal and seems to lock on a lot quicker. So far haven't had that many issues with it besides the network still sucking of course. If you don't have a good plan on Sprint I would leave. I think it will get better over time but it's still going to be a while yet. I have had problems since last July.
[Sprint HTC One (M8)] Success100:
I left Verizon because of the ridiculous bills I kept getting. Boy is their network amazing. Signal and LTE everywhere.

Got the Sprint HTC one m8. I mean Sprint is just terrible. LTE barely works barely have a signal anywhere. Love the phone but only on WiFi around the City
[Sprint HTC One (M8)] reverepats:
Same here. I got I think 9 people on my Sprint family plan, we've had Sprint for over 10 years now. I left for Verizon when the galaxy Nexus was relleased. Man, I loved Verizon, but my bill was upwards of $120 per month. Luckily I got to deal where if yo bought 2 or 5 GB plan, they would double it. So i had 10 GB of data at that time. The service was unbelievable, but I hated the price. So after 9 months, I came back to Sprint. Here in Boston, the service is great, but I've also seen a sporadic in and out connectivity.

[Moto X Q&A] csytracy:
Please look at the end of time axis. During the charging, the battery level jump from 78 to 100 suddenly.

I found similar jumping several times, and I did a calibration by completely discharging the battery. During discharging, the last 1 percent is supper durable. However, after a couple of days, the jump reappear again.

Any ideas?
[Moto X Q&A] c19932:
My battery jumps from 80 to full when charging too
[Moto X Q&A] ConstantHero:
I've noticed that as well anytime I charge from anything except dead 0 it jumps from 80 to 100 from 0% it charges smooth to 100
[Moto X Q&A] csytracy:
Exactly. Did you also notice that the last 1% is supper durable?
[Moto X Q&A] Bionic22:
Yeah I've noticed this as well. It was very surprising because my old phone would take hours to charge but the Moto X took almost 1/3 of the time. But then battery does last long after the full charge so NO COMPLAINTS here :good::good::laugh:
[Moto X Q&A] c19932:
yeah i feel like the battery percentage is not accurate at all on the moto x. I compared it with mV voltages in battery monitor pro and its always off...
[Moto X Q&A] jayboyyyy:
your phone is guessing what your battery percentage is. if you want to fix it, drain phone down until it completely dies. then charge it to 100% without turning it back on. It will recalibrate your phone battery stats and you no longer will have the phone jump from 80-100% when charging.
[Moto X Q&A] csytracy:
I have done that twice. This symptom reappears after several days.

What you need is a rooted i-537 with safstrap installed.

make sure phone is rooted and you have safstrap installed.

prevent you phone from updating itself as shown in the root guide in this forum.

get a copy of the tethering provisioning apk from a custom rom. One that worked for me is attached to this thread.

put the custom tetherprovisiong apk on an external sim card for access. boot into safestrap and make sure stock rom is selected.

mount filesystem then open up safestaps file explorer and delete tetherprovisioning apd and tetherprovisioning odex from system/apps folder. Confirm that it is deleted.

Now paste the custom tetherprovisioning.apk into the same system/apps folder. Reboot phone into stock, rooted rom and enjoy wifi tether.

You should now be able to turn off and on with the normal method.

[8125, K-JAM, P4300, MDA Vario General] Frankk:
I have a Qtek 9100 with i-mate k-jam OS.

I have this issue with volume, whatever volume level or settings I use I always get notification sound for "data connection terminated" (translated from italian, maybe original english version differs).

In my opinion when I disable all sounds tapping in volume icon in the top bar every sound and notification should be disabled except the alarm. On the contrary alarm in silenced while the notification mentioned above still plays (there are others, but I cen't remember now).

While the alarm not playing is not a big issue to me, the notifications playing in silenced mode annoys me a lot.

Is there a way to make it completely quiet? Maybe a registry key, or something...

Thanks,

[Asus  Eee Pad Transformer Prime] kokopuphz:
Development of this kernel was aimed at resolving the I/O issues at the root of the problem, by fixing some improper implementations as well as updating the source code.

I am not a big fan of disabling fsync or modifying SQLite library to disable sync. Both these temporary workarounds will alleviate the problems, however they introduce very real risks of corrupting data or at times corrupting an entire partition, resulting in a brick. As such, I will not be touching these, however the mods needed for dynamic fsync will be included in the kernel.

I have only tested on the stock TF201 bootloader. I have not confirmed if it will work on the HB bootloader (TF300T bootloader), however with build v1.0.1, the bootloader restriction of the installer has been removed for those that are feeling adventurous... however please make sure to have NvFlash enabled first!!

Thanks to Namidairo, Voyager2k, and others for the hard work on the kernel.

Known issues:

Reboot does not work.

Unknown other bugs that are bound to come up, as everything has not been thoroughly tested.

Todo:

Implement other sdhci-tegra specific algorithm. Google/Nvidia seem to be working hard on completely reworking the code from scratch for 3.10 implementation.

Look into adding wake lock for bkops so that bkops can be done when tablet is going idle > this should help reduce overhead when active

Source can be found here.

Notes:

There are bound to be several bugs in the implementation. Use at your own risk.

Sounds very intriguing. Would love to see something to make the prime leaner and less sluggish. But, I'm a little gun shy for trying out on cm11 - Im not really in a position to spend a lot of time trying to unbrick if things aren't compatible the first go around. I'll be keeping my eye on this, though. Thanks for the work on this!!

Hi

I would like to test your kernels, which boot loader do there work with?, I am using the updated wookie version (10.6.1.27.1) and get an error saying that my prime is a tf300 not an tf201 on flashing your CM 11 version

sent from my TF201

I'm going to try this, currently have cm 10.2

I tried all the cache2sd and data2sd stuff and it didnt seem to help much, further evidence that it might not be a h/w issue
[Asus  Eee Pad Transformer Prime] scote:
worked ok on cm 10.2, cant say I noticed much difference with performance.

I've just flashed cm 11, the tablet is flying again, this is what normally happens with the tf201, when you flash a new rom its fast for a while then it gradually slows down. I did forget to do a wipe so a couple of apps are misbehaving, I juts clear their data or uninstall updates if its a system app.

Now the big question is if I install this kernel now will the tablet not slow down again after a few days/weeks of usage?

I think I'll give it a go, I'm on the verge of recycling this tablet now so if anything can inject some life into it its worth trying.

edit: well I tried it on cm 4.4.2 unofficial thats posted on here and it didnt boot, just got the spinning cm logo, left it for a few minutes.
[Asus  Eee Pad Transformer Prime] kokopuphz:
This is exactly what should be resolved with this kernel.

An internal mmc usually does automatic maintenance type activities on every write and erase. With emmc 4.41, a new feature called background operations was introduced, which allows for the delay of the maintenance operations.

There are two problems with this. First, it was left up to the kernel developer to implement the algorithm of when to execute the background operations and when to stop them. The second problem is that once the background operation is enabled on an mmc, it can never ever be disabled. Thus, once enabled, the kernel MUST issue the background operation command, or all the necessary maintenance operations will never happen, where as on a card with it not enabled the maintenance activity occurs on all writes.

ASUS has enabled background operations on the mmc, and the simple algorithm implemented by nvidia is causing some lag.

Most custom ROMs are compiled with the background operation logic disabled, thus the algorithm is skipped altogether. This leads to eventual degradation in performance due to the lack of maintenance command being issued.

In the kernel I a working on, I attempt to address this issue by implementing a better algorithm for bkops. With the bkops logic in place, the mmc should work in the way that it was meant to work, and there should be minimal degradation of performance over time.

I'll try to resolve the issue with cm11 soon.
[Asus  Eee Pad Transformer Prime] mythoc:
I dont think there is any way to see real perfomance improvements without formatting to f2fs. trust me i am running this new file system right now with prime, and i dont really care about data corruption (would only happen if the tablet shutsdown by accident of course, i wont allow that!). The i/o perfomance without data2sd is over 3 times faster. Play safe with f2fs and you are never gonna return to ext4. i can only imagine what data2sd plus f2fs can do...
[Asus  Eee Pad Transformer Prime] scote:
My tablet is more or less permantly docked and on ac power and I very rarely get random reboots. Corruption would be of little worry to me. If the mmc maintenance is implemented in the filesystem layer and f2fs currently does a better job of it than ext4 then it may be worth me trying that. If the mmc maint is in a layer below filesys then the work the op is doing will help in either case, is that correct?
[Asus  Eee Pad Transformer Prime] kokopuphz:
[MENTION=453028]scote[/MENTION]

You're absolutely right. The changes are on an underlying layer, thus it should help both.

[MENTION=4126442]mythoc[/MENTION]

As a reference, could you let us know if you used any benchmark for the comparison between f2fs and ext4?
[Asus  Eee Pad Transformer Prime] scote:
I'm thinking about trying f2fs on my cm11 rom. As I have a /data that is ext4 and has been in use for a few months I think it may be good to benchmark that first, then again after conversion to f2fs, and then again when this kernel is fixed for cm11.

I've tried a few storage benchmarks from the play store, is there a good one that has selectable partitions and has random writes?
[Asus  Eee Pad Transformer Prime] mythoc:
damn my benchmark results from ext4 are gone. i can only test f2fs now with antutu i guess. i remember getting total of 15-16k score, with 1192 storage i/o and and 630* database i/o. I dont really trust benchmarks much, you feel the difference anyway :)
