Jumm wonder why some have problems with TW roms and others dont? Im running stock mg3 with 8/25 flawlessly. I also have a i337m if that matters
[T-Mobile Samsung Galaxy S 4] ktoonsez:
I need someone to try my ATT version to narrow down the problem. U up for it? There is no reason for the jizzer to not boot when 3000 people on the other variants r booting fine. This will at least narrow it down to maybe a ramdisk issue. Hopefully u or someone can try that for me.
[T-Mobile Samsung Galaxy S 4] Gadianton:
I'm actually on T-Mobile, but yeah I'll try it.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Lol. I know. That's the point of the test to narrow it down :)
[T-Mobile Samsung Galaxy S 4] Gadianton:
I tried out the 8/25 from the ATT thread. I have the same problem with boot looping.

EDIT - And 8/20 works.

LuigiBall: I just wanted to thank you for helping me get the kernel back on track. My issue was with the GPU voltage table, which had apparently somehow set itself to basically nothing. I went in and reloaded the stock voltage table and things have been fine since.

To any else who may suddenly get unbearable lag when using Simple or Performance GPU Governors, make sure you check the voltage, which seems to occasionally set itself to nothing, reload the stock voltage table, and things should be fine. If that does not work, try to wipe cache/dalvik, and reinstall kernel again. I personally had never messed with the actual GPU voltages, so I have no clue how they became messed up, but that was the issue.

:D
[T-Mobile Samsung Galaxy S 4] ktoonsez:
LOL, thats awesome. So Touchwiz is not longer compatible with Touchwiz, what a great ROM that is!!!!!!!!!!!!!!!!! :silly: :eek: :cowboy:
[T-Mobile Samsung Galaxy S 4] Tunasty:
lol you and your jizzer jokes :laugh::laugh:
[T-Mobile Samsung Galaxy S 4] Gadianton:
lol yeah. I've meaning to switch to something better. I need WiFi calling... anyone have a recommendation to a good rom with WiFi calling?

My office has a terrible cell signal, but great WiFi signal.

Maybe this will finally overcome the inertia and have me wipe and reload all my data... (hmm I wonder if someone hacked the GE roms with wifi calling... off to the internet to search.)
[T-Mobile Samsung Galaxy S 4] ktoonsez:
LOL, you got to admit that it is pure comedy that the same kernel compiled on 2 different days wont boot this TMO phone now, that is hilarious.
[T-Mobile Samsung Galaxy S 4] Tunasty:
Yes, ios 7 :p :cool: ;)

Hilarious yet retarded at the same time lol
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Crap, that was not too smart of me, I forgot that ATT is LOKI'd, it will never boot your phones. Can you try the INTL one instead???? Here is a direct link to the INTL 4.2.2:

http://ktoonsez.jonathanjsimon.com/sgs4/TW/KT-SGS4-JB4.2-TW-INTL-08.25.2013.zip
[T-Mobile Samsung Galaxy S 4] Gadianton:
That version booted up fine.

EDIT: Playing with it for a few minutes it actually seems much faster than 8/20... the cache rebuilding went by so quick that I hardly saw it while I was working. Might be placebo... anyway, it works fine so far.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Very odd.
[T-Mobile Samsung Galaxy S 4] elesbb:
So it does seem to be ramdisk related. Are you gonna do another build? I was gonna unpack your 8/20 and your 8/25 kernels and swap out the ramdisk.gz (should work right?) and repack it. Unless there are updates to the ramdisk then i won't do that.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Go ahead and try that and see if it works if you have time, would be a big help. It could still be something else but I think it has to be ramdisk.
[T-Mobile Samsung Galaxy S 4] elesbb:
maybe something screwy with init.rc?

---------- Post added at 09:58 PM ---------- Previous post was at 09:57 PM ----------

I just gotta get everything onto my computer (been using phone to dl all your kernel updates) so that shouldnt be too hard. Give me 15 minutes (if i don't screw anything up in terminal anyhow xD)

---------- Post added at 10:10 PM ---------- Previous post was at 09:58 PM ----------

Rebooting now.

---------- Post added at 10:16 PM ---------- Previous post was at 10:10 PM ----------

Okay i borked something. it didn't even boot.. xD this worked before when i was testing the init.rc for the many data mount points.. ugh
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Ok, Im back to my hotel, Ill build soemthing with INTL ramdisk.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Ok, guys, try this:

[T-Mobile Samsung Galaxy S 4] Gadianton:
Looks like it is working. Booting up now.

EDIT: Yup. working. booted right up.
[T-Mobile Samsung Galaxy S 4] elesbb:
This worked :)
[T-Mobile Samsung Galaxy S 4] Gadianton:
By the way, I think the GPU Voltage thing from a poster up the thread was causing all of my problems from 7/7... I cleared out all settings for the boot loop this morning and things have been running butter smooth since then.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Awesome. Try everything to make sure everything is ok, like data, wifi stuff like that.
[T-Mobile Samsung Galaxy S 4] elesbb:
Using it now :) everything is a go. However I did have a reboot shortly after installing. Last_kmsg is on my computer but the kernel panic was caused by something to do with ext4-fs I'll post it once I'm done eating.

Btw here is that last_kmsg i was talking about earlier.
[T-Mobile Samsung Galaxy S 4] gaww:
I have been using Wicked - WiFi worked on all versions - using 5.0 now. Would be great if there was a GE ROM with WiFi calling (ot Omega), but understand it is too difficult and proprietary to hack so far. Works real good with this kernel (a few minor functions do not work after 6/10 version, but don't use them so I stay current).
[T-Mobile Samsung Galaxy S 4] dragon-son:
Odd issue I've encountered. When restoring settings from a backup file the gpu voltages go to lowest settings. Duplicated several times. Restored defaults. Imported backup. Gpu voltages went low.

Also CM 10.2 is so much faster than the TouchWiz I was on before.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
That's because you need to load stock GPU table BEFORE applying or restoring any settings. If you already have then you'd need to clear Ktweaker data and start over.
[T-Mobile Samsung Galaxy S 4] dragon-son:
I was a little off before.

Forced ktweaker to stop.

Cleared cache

Cleared data

Launched ktweaker it has values for gpu

Load defaults in ktweaker

Gpu values gone 0%

Load stock table and apply

Close ktweaker and verify setting still there

restore settings values still there.

Load defaults

Gpu values gone 0%

Load stock table and apply

Restore settings values still there.

So it appears that when I load defaults on ktweaker, that's when the value for gpu goes to 0 for me.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
You are right on the "Load Defaults" from the "Main" screen, I just got that fixed. BUT, as I have stated before, NEVER restore a file that is from an older KTweaker or you are just asking for trouble. When ever I add big items like that, you need to rebuild/save your backups so you are not writing old file format to you saved settings.
[T-Mobile Samsung Galaxy S 4] dragon-son:
Yeah I know not to restore from old stuff, learned that the hard way back when I had my G2 phone. So much can go wrong with that. Also why I full wipe everything, and don't restore app data when flashing a new ROM.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Do you honestly rely on those numbers to determine real-world use?
[T-Mobile Samsung Galaxy S 4] CousinMikeyP:
I use ktoonsez's recommended settings. Both battery, and performance it is the best of both worlds

[T-Mobile Samsung Galaxy S 4] PattyNYC:
Try lowering your max frequency to 2052 or 1998. I don't think your CPU can handle 2160. I had the same problem as you but my benchmarks went up after I adjusted the overclock. Oops just read that you are using the powersave governor which locks you into your lowest frequency. Try the interactive governor if performance is a must.
[T-Mobile Samsung Galaxy S 4] stevessvt:
I bet you got **** blocked by thermal throttling. Try letting it chill for a bit then retry.
[T-Mobile Samsung Galaxy S 4] Ningcube89:
Quick question guys. Any time I use the 8/27 kernel for 4.3 I can't play video at all, phone locks up and reset. As soon as I go back to 8/21 I believe everything works fine. Any insight in to why? Thanks. Favorite kernel by far just odd that that happens.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
It's because in the newer version you need to load stock GPU table in Ktweaker BEFORE applying any settings. Also note that when new features such as GPU voltage control are added you should NEVER restore previous settings. If you have then you'll need to clear Ktweaker data and force stop then load stock GPU table and manually input your settings.
[T-Mobile Samsung Galaxy S 4] Ningcube89:
Appreciate the insight.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
That is definitely it since stock does no thermal throttle when benchmark apps are detected.
[T-Mobile Samsung Galaxy S 4] gaww:
I had been restoring backed up settings when I flashed ROM and kernel again or with an updated kernel. I only have done very basic settings (Some OC/UV, governor selection, fast charge, min max screen off/charging, etc.) Will these still possibly cause problems when upgrading?
[T-Mobile Samsung Galaxy S 4] MavereXx:
Any of you guys still experiencing sleep of deaths? I was getting it on 8/26 3-4 times per day plus random reboots and been staying on 8/20 till things are more stable... but I think I might upgrade again and post last kernel msg to isolate the issue since I haven't heard any word about it. My only guess which could make it my error is possibly too much undervolting, but I thought I had that tuned good.. and yes I remade my settings fom scratch and got the defaults for gpu before uv'ing -75mv
[T-Mobile Samsung Galaxy S 4] MavereXx:
Oh and I almost forgot - on every reboot my ktweaker app hangs on load - I have to delete cache EVERY time to get it to work, small hassle but still an annoying bug.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
The issue is due to your GPU voltages You need to load stock GPU table BEFORE applying/restoring settings. You also shouldn't restore Ktweaker data from previous versions. When new features such as GPU voltage control are added you need to rebuild your settings for the best possible results. If you've already applied any settings then clear Ktweaker data and force stop then load stock GPU table in Ktweaker then manually apply your settings.
[T-Mobile Samsung Galaxy S 4] MavereXx:
Lol I'm sorry, don't mean to be rude, but it seems you didn't read the bit at the end and just jumped to the canned message. Anyways I've updated to 8-27 and kept essentially the same perfected settings I've discovered myself before.. well see how it goes this build :)

P.S. Still experiencing the ktweaker application hanging on launch every boot. Have to wipe data every time. Maybe physically delete the application then reflash the kernel? Using stock tw rom. AMDJ
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
No I read it. Problem was I must've misunderstood the end of your OP.. Based on that I assumed you had applied your settings even before loading the defaults. My bad lol
[T-Mobile Samsung Galaxy S 4] MavereXx:
Hey it's all good, I understand the amount of newbies you have to deal with on an hourly basis.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Yup. Have had to repeat myself far too many times now lol but as far your problem goes I normally do recommend removing the app before updating the kernel. It's not absolutely required but it has made a difference for some. If you can't seem to get around it you can try my recommended procedure and hopefully it helps.

1) Navigate to Settengs > Apps > All > Ktweaker

2) Clear cache and data then force stop

3) {Optional} Open any root browser, mount as r/w, then navigate to /system/app/ and delete Ktweaker apk

4) {Optional} Clear all Superuser logs

5) Reboot Recovery

6) Flash kernel

7) Wipe cache/dalvik

8) Fix permissions

9) Reboot

10) Go into Ktweaker

11) Navigate to Voltages > GPU > Menu > Load Stock Table

12) Hit Apply

13) Manually apply settings

14) Profit?

[T-Mobile Samsung Galaxy S 4] lordcheeto03:
Hey [MENTION=5082757]LuigiBull23[/MENTION], what is the default voltage @ 1890mhz? One of my backups had it set to 1125mV, which IIRC was a -50mV undervolt across the board; yet when I select "load defaults" it throws the voltage up to 1400mV @ 1890mhz. Loading your settings, 1890mhz gets set to 1220mV. I know that I didn't u/v by 375mV, your settings are supposed to have a -30 u/v, but that still looks weird, so what am I missing here? This is just using 1890 as a baseline; obviously the other steps are u/v'd as well.
[T-Mobile Samsung Galaxy S 4] MavereXx:
Regular battery. Just took this SS. 1998mhz oc'ed 81mhz uc'ed

Thanks ktoonsez :)
[T-Mobile Samsung Galaxy S 4] getsum:

[T-Mobile Samsung Galaxy S 4] HampTheToker:
LuigiBull23's settings from his thread in the General section and the methods outlined in the Better Battery Life While Idle thread also in the General section.

Running CM10.2 as well.

Edit: Also, I'm on a stock battery. Most of my screen on time came from watching episodes of Under The Dome.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Looks like I got myself a new challenge lol. Awesome run!! Some of the best results I've seen.

Default is 1890 - 1250mV. - 30 and you get 1220mV. You should clear Ktweaker data if you haven't already then load stock GPU table. After that then you may restore the settings and you should see 1890 - 1220mV and so on. Unless you wanna go further, I suggest just leaving it at that lol
[T-Mobile Samsung Galaxy S 4] lordcheeto03:
Ok, force stop + clear data + reboot gives me 1890mhz @ 1175mV on the latest kernel. 1250mV corresponds to 2052mhz.. Something isn't right here... :rolleyes: The picture is my stock table..
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Which build are you on? Have you tried following my update procedure from the previous page?
[T-Mobile Samsung Galaxy S 4] lvlonkey:
I'm just wondering if any one elses phone can maintain the stock max clock speed of 1890 without hitting the temperature limit and being throttled? I have a global -50 uv and I was running the stability test to make sure its ok. The test didn't run for long before I noticed the core speed kept dropping. I went into ktweaker to.check temps and notice I was constatnly hitting 70c and kept getting throttled down. I have noticed my phone gets pretty warm with just prolonged web.browsing. is this normal? what is the point of having a powerful processor if it gets so hot it gets throttled down anyways? I recently just got my s4 and note I'm wondering if it should get this hot and if I should try to return it for another s4. I hope not because I have a glass screen protector and those aren't exactly cheap.
[T-Mobile Samsung Galaxy S 4] MavereXx:
Stay on that screen press the menu button...... and load stock table! *magic*
[T-Mobile Samsung Galaxy S 4] lordcheeto03:
Yes,I have. I've also clean flashed my rom then flashed the kernel on top.. the stock table even after a clean flash shows 1175 as well.

Did that, 1175 still.. I'm just not gonna complain.. I'm sitting with 1890mhz @ 1125mV.. that's -125 from the apparent stock table across the board stable.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
When you flashed the ROM did you reboot before flashing the kernel. Probably best to do that for the best possible results.

KT is the best! I went back to jizzer because the bluetooth was driving me crazy in AOSP. First and foremost the audio cracking is fixed! Don't know if it's faux sound driver or you but in either case I'm extremely grateful. The performance is something I've never seen on a lagy bogged down jizzer rom! It's so smooth, I can't thank you enough. I can now tolerate it. Have a good weekend and holiday!

[T-Mobile Samsung Galaxy S 4] MavereXx:
Yeah I tried that still crashes on boot... idk what's going on with the app.. been this way for me since 8/15ish version. Deleting ktweaker.apk and reflash did nothing
[T-Mobile Samsung Galaxy S 4] Poser:
Its weird... my bluetooth performance on SLIM was awful on googs music, but never an issue steaming pandora. However, I just updated to Beta4 and I am not having the bluetooth issues I was before. I am going to give it a day or two... then I will flash KT again. The boxed SLIM kernel is solid, but I need me my dose of awesome. I know that their were some changes to jf device tree specifically addressing bluetooth.
[T-Mobile Samsung Galaxy S 4] mike216:
Bluetooth worked OK besides trying to use this new moga controller?

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] lordcheeto03:
I've done it both ways; flash ROM, kernel, and gapps then boot and flash rom + gapps, boot and setup, then flash the kernel... I still get the same voltage table each time. It's been like this ever since this kernel was released; I just always assumed the stock voltage at 1890 was 1175. What got me looking at it though was when I tried to just load defaults on the main menu and noticed it had shot up to 1400mV. That made me take a closer look at what your settings put the voltages to and it just confused me even further. Doesn't matter if I'm on AOSP or GE, both 4.2.2 and 4.3, or any version of TW, my voltages are never defaulted to 2250 and down from 1890mhz.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Something is either corrupt in your ROM and need to do a full wipe or just a crappy ROM. Nothing wrong with the app since thousands of people are using it and dont have the issue you have.
[T-Mobile Samsung Galaxy S 4] MavereXx:
Must be corrupt somewhere then... its a stock TW rom... haven't edited that much of the system files just rooted loki'd ktweaked and debloated... interestingly enough this was occurring before my latest wipe. Hmmm.. ill have to try.
[T-Mobile Samsung Galaxy S 4] MavereXx:
Ktoonsez I found out how to fix the bug. I Set apply settings on boot. When I had it disabled on boot ktweaker would crash... until I wiped data... So this might actually be a legitimate bug and not a crappy ROM.
[T-Mobile Samsung Galaxy S 4] dynospectrum:
I don't think it's a bug lol
[T-Mobile Samsung Galaxy S 4] MavereXx:
Lol it definitely is but if it shows up for anyone else I found the solution lol

On 8/27 build my cpu temperature is 45-55 °C while charging and the screen is getting pretty warm.... I compared it to stock kernel which never goes above 45°C while charging...... I don't mess with settings in Ktweaker (I leave everything default) I have a i337m S4..... Is there something I can do to remedy this hot charging problem..... Otherwise this kernel runs great with excellent deep sleep

Thanks
[T-Mobile Samsung Galaxy S 4] galaxys3man30:
Is that battery temp or cpu temp? What app are you using to monitor temp? Its going to get warm when charging its the battery getting hot im not totally sure on this but I think kt kernel increases the charging rate where it charges your battery faster that would cause the increase in heat on the screen especially on a car charger but in ktweaker app in extras you can control the mhz while charging that would keep the cpu idled down during charging and help with the temp as well and if your using the phone while charging its going to get warm because your using the cpu and its mixing with the battery heat that would make feel hotter as well

System tuner for cpu temperature..... I don't use the phone while charging..... I'll have a look at the charging currents.... So maybe it is set as fast charge by default then?
[T-Mobile Samsung Galaxy S 4] elesbb:
It's not a bug. A bug is persistent across all devices using that app. If no one else is having issues then it's not a bug. It's something isolated to your device/setup.
