[HELP] custom rom an UNDERclocking - G Pad 8.3 Q&A, Help & Troubleshooting

i need to UNDERclock my V500 the CPU and also the GPU.
with stock rooted no luck, only the 1st core and not the other 3 and also the GPU, tryed ALL apps i've fund.
tested with PERFMON http://forum.xda-developers.com/showthread.php?t=1933284 that will show the frequency of the cores
more info on http://forum.xda-developers.com/showthread.php?t=2666338
i think is the qualcomm mpdecision function...
is there any CUSTOM ROM that will do the trick? please check with PERFMON and report!
it's crucial for me, PLEASE.

Nokia X CPU and GPU overclock

Hello,
Is there a software which can overclock the cpu and gpu of Nokia X and is it necessary to wait for a modified kernel in order such software to be able to work?

The NULL Kernel already allows for overclocking. Check the Android Development Section and read the NULL Kernel thread. I believe its overclocked.

Thank you for the fast reply. I checked the thread. It seems they managed to overclock the gpu but there is no option for cpu. I guess I will need to wait and hope someone to be able to implement cpu overclocking.
I tried a few apps (SetCPU, Titanium Tweaker, KUI), but none of them overclocked my CPU. Using 3.4.86 kernel that comes with dhacker's 29 AOSP ROM.

[KERNEL][FLASH METHOD] Kernels settings for S3 NEO - stock Lollipop and CM12, 4.4.2-4

I want to create a thread about settings for every custom kernels on our S3 NEO with Lollipop Stock and CM11, CM12, stock 4.4.2 and 4.4.4 ROM.
If You are advanced or expert in the subject of krenels, parameters and features put to this thread Your settings.
This thread, I thnik, helps novice in search for the best settings to be the rom fast, stable and smooth.
So, please placing here and debate on settings the kernels.
Maybe for a CM11, CM12, CM12.1, CM13, stock 4.4.2 and 4.4.4 also 5.0.1 this settings works well, too.
Try and tell us
The Poll is only for stock TW 5.1.1 ROMs.
Thanks for Devs who made the kernels for S3 NEO:
- @sev3n1985
- @Renix63
- @LGaljo
- @nikita36078
- @oranaise2412
- if I forgot about someone - tell me.
Thanks to @gsstudios for giude about governors and I/O shedulers.
Thanks to Mike Barrett for video about Kernel Adiutor settings.

Important - only for custom kernels
The phone must be rooted.
1. Before flash any new kernel do backup your rom, boot, recovery, preload and data ex. via recovery.
2. After flash the new kernel always do wipe cache and dalvik cache in recovery and next restart the phone. (restarts takes about 5min)
3. CPU frequencis and governours are important things in rom's speed.
4. CPU freq at 1593MHz may destabilized your phone - heating problem and sometimes random reboots.
5. If You want to OC CPU - have to turn off MPDecision Hotplug and select another one or nothing (MPD may do CPU freq not stable - is always good for only stock frequencis so from (192) 300 to 1401MHz).
6. Sometimes the new kernels have to root again via flash superSU update via recovery ex. like eMotion kernel.
7. Try any changes - don't be afraid - kernel not bite If so go wrong - always have backup
Good luck.
If anyone have another advices - feel free....
The difference between kernels with zRam and zSwap options:
- zRam is a kernel with virtual memory in Internal Memory your phone (compressed) for most users
- zSwap is a kernel for the SD card with swap partition for our phone ex. 512 or 1024 Mb, so if You have not swap partition in Your SD card - do not flash this kernel (no good resoults).
Heating and random reboots problem
This dependent of frequensic CPU and if is it so CPU max freq probably is set at 1593MHz.
If we to much OC our CPU's then our phones may have some lags and freezes or reboots (after call or in camera app).
So if you have this symptoms then you have to set CPU OC max to 1401MHz or 1497MHz.
If it no helps so maybe the kernel is wrong compiled with bad linux settings - and only change the kernel for another one.
Guide for CPU governors and I/O shedulers and others settings in Kernel Adiutor
Please read THIS - big thanks to @gsstudios for this gov guide.
Please watch THIS - thx to Mike Barrett for video about settings in Kernel Adiutor.
It's a good guides for everyone.
Only my conclusions
From my experience with OC CPU and use different kernels (in stock and CM series ROMs) the stable max freq CPU is at 1497MHz.
If You want better battery life select max CPU at 1401MHz or even 1300MHz - 1190MHz.
For better battery life You can try :
- Multicore Power Saving - ON
- CPU gov at Ondemand, Intelidemand, arteractive, inteliactive (without frequent lags)
- GPU gov set at conservative (in new Renix kernel) or msm-adreno-tz
- if you only listen to music then set Max Cores Screen Off at 1 CPU and max freq at 600 - 700 MHz - for media player is enaugh.
- Power Suspend Mode at LCD Panel or Hybrid.
My steps for install all things like rom, fixes, xposed, kernels, ect. :
1. Wipe system, data, cache and dalvik cache - no restart the phone
2. Flash any ROM - no restart the phone
3. Wipe cache and dalvik cache then restart the phone
4. Flash possibly another kernel ex. Renix's, eMotion's... I do it in this step 'couse sometimes after that We have to install ex. camera fix - again in Renix kernel or superSU in eMotion kernel
5. Flash any fix for the point ROM (like RIL, key fix, mixer fix, camera fix... others) then restart the phone
6. Flash superSU (if the rom has not rooted) and possibly busybox for advanced (change build.prop in Kernel Adiutor for example) then restart the phone next go into superSU ( the app install binary) next do settings and out - the same with busybox (have to install libs)
7. Install the xposed app next go to the recovery and flash xposed sdk22(Lollipop) (23 for MM) ex. v85 by wanam, next wipe cache and dalvik cache and restart the phone
8. That's all - in my phone works good, I did and do it by 2-3 years and no problem.
Remember - after wipe cache and dalvik cache the phone's booting time will take a 5-7min.
Thanks for this thread! ^-^
I think I'll post my stats too! I got a perfect balanced mix with 3.5 renix. But for now I wanted to try the new one with boeffla kernel sources ^-^

Hello.
If you set CPU at 1497MHz or lower so no random reboots in I9301I.
I don't know how it look in I9300I.
So if someone can write abaut it so will be nice....

I'm happy to helped You bro.
What configaration You have ? at 1497MHz (pics) or 1305MHz (video) ? and what's kernel ?
It will be clarity for others.
If You can - edit Your post about above.. ? thx man.
Nice if it works in another phone

I have a I9301I and use Motion ROM 17.0 with eMotion kernel. Motion ROM 'as is' gave me frequent random reboots, so I tried Renix63 kernel. V2.0 fixed the random reboots, but LED lights stopped working. Later versions fixed this but introduced the problem of the phone freezing when responding to notifications and occasionally switched off the phone completely. I then tried eMotion ROM from sev3n1985. LEDs work, no random reboots, no freezes, no switch offs. It just works. nalas's second post in this thread has 20 screenshots of recommended tweaks to the Renix63 kernel. I prefer something that works out of the box.

With all due respect to nalas and Renix63 I don't understand the logic of producing a kernel that's overclocked to 1593MHz which then has to be reduced to 1401/1497 via Kernel Adiutor in order to prevent freezes or reboots.
Other users have had different experiences, so there there may be other factors to consider - variances in hardware, apps etc. - this is just my experience.
Apart from that - huge props to the devs here. If it were not for them I'd still be running TW 4.4.2.

I tested Ciro's rom but It was buggy for me (dialer does not appear but the phone call was running)
WiFi not working
SIM not working
I will try Motion Rom.

[SOLVED] [H815] How to disable Big cores on startup? Any script do that?

I have the Infinite BootLoop Issue (the hardware issue) and I'm trying to disable the 2 big cores at startup. With Kernel Adiutor I can disable one core, but when I try to disable the second, it goes online automatically. I tryed this with different governor but I cannot disable both cores (I must do it manually modifying files /sys/devices/system/cpu/cpu4/online and the cpu5 one). There is a kernel with those cores disabled, but it's old. So, is there a script that can turn off the big cores during startup?
I have H815 eur and MM (with Imperium ROM and Imperium Kernel)
Solved, with this thread https://forum.xda-developers.com/g4/general/fix-lg-g4-bootloop-issue-t3647538

Kernal Adiutor CPU frequency setting doesn't stick, should I change ROM / Kernel?

As above. Trying to underclock it for better power efficiency so that it can decode videos faster by avoiding throttling.
Can't remember what ROM I flashed when rooting, just followed one of the many guides out there.

I have a problem with the processor

The maximum frequently of 2 cores is 1820mhz while it should go to 2150mhz, and I can't change with any application with root
Which rom? Any custom Kernel? You have to give use more informations if you expect help
I have seen that too, on the original global rom. I think that's how the snapdragon 821 works, based on how many cores are loaded.
