Hi guys,
I own an Nexus 4 with parts of the screen not responding. I got a new phone now (Ecoo E04 Plus), now I want to build a iPod-alternative. Now to my question, whats the best ROM for that purpose? It needs a long battery life in airplane mode. Second question anyone nows an that changes ur homescreen to a nice media player? (I thought of Themer) And my third question is what kernel would you prefer? Thanks for your help.

i would suggest stock rom with a few mods or a custom rom. the important thing is custom kernel.
the way i would do it is:
1. stock with xposed framework+gravity box. that way you can enable volume keys to change track
2. chroma rom. ia currently use chroma rom an it is rock stable and it has tweaks built in one of them is volume keys to change track.
in both cases i would install a custom kernel f.e. franco kernel for better battery life. if you want to maximize the battery life you can undervolt/underclock/disable cores. my phone is always undervolted 150mV.
my advice is undervolt (undervolting to much will reboot your phone. my cpu undervolt limit is 150mV so keep that in mind)and disable two cores. two cores are already capable to handle everything. the cpu frequency should be 384mhz - 1.3ghz or 1.5 ghz. see what is good for you. know that the higher the mhz the more power you need
also remember to disable sync and, if you don't need, don't install google services for battery again.
for maximizing battery i don't know which android version is best. i would go to android 4.4.4 or 5.1.1
for home screen i would suggest a widget. also you can also make your player start automatically when android start. there a lot of app in playstore for that.
P.S. if you encourter any stuttering during music playback one reason could be the low frequency of the cpu. i had a problem like this some time ago that is no more on android5.1.1. the solution for me was to change the lower cpu frequency to 512mhz or 700mhz. this solved my problem.
P.S.2 for changing the kernel setting i use franco kernel app. it is a paid app and simple to use. the free franco kernel will flash the appropriate kernel for you. you can find a lot of apps in the store that are free one populare is synapse if i remember correctly.
if you need anything else feel free to ask. hope i helped

Hello.
I've got a stock Android 3.2.1 (A501 4.066.29 COM GEN1) rooted with Stock/HV/Taboonay V3.7 for HC 3.2 16-10 - 1.64Ghz/UV control kernel.
The question is:
how to set cpufreq parameters (governor, max_freq,..) WITHOUT using 3rd party apps so that the parameters were restored after reboot.
Thank you for reading this.
Either the kernel needs to support init.d scripts or a service needs to execute on boot.
That kernel doesn't support init.d and Voltage Control has a startup service.

Forgive my ignorance but I can't put to use your answer.
I don't get where is Voltage Control and what I have to do.
Get Voltage Control from the market, make adjustments, save as boot. You'll be given the option to save as init.d script or startup service.
Well.. I tested it. Odd app.
First of all it can see only one core. It's funny. After reboot cpu0 works in conservative mode, max_freq 1.4 GHz and cpu1 in ondemand mode, 1.0 GHz.
I tried to edit init.d script and add the 2nd core but after reboot cpu worked with the default kernel values - script didn't work at all.
Moreover Voltage Control shows voltages turned upside down - the less cpu frequency the bigger voltage values. I fear to use this app
Download setcpu or antutu cpu master it recognizes dualcore , has the boot option
More education would be advised To you PLEASE DONT BREAK YOUR TABLET
Please do not take this the wrong way..
it does sound like you do not know what your doing.. I suggest you read more about over clocking./under voltage of a TEGRA 2 DEVICE.. That will get you more understanding about what you need to do. And maybe even help you decide if you really want to do this or not.. There is alot of resources online about this subject. I have tried custom kernel with set cpu.. I use it on my 650 mhz phone. clock it to 768. but it has a huge battry issue when running at that speed.Not to mention It would be dangerous to leave it on my purse with something running might be a fire bug.. GOOD LUCK .
Basically lower voltage at higher frequencies keeps the CPU stable. Leaving it linear would increase temperature exponentially.
Script Manager can run scripts on startup but I don't know how you could disable them if they keep it from starting up.
I didn't know about VC and dual core though. My bad.

I don't understand? You want something that does the same thing but you don't want to know it's there?
I found one app called System Tuner that lets you adjust CPU frequencies individually. I don't know why though.

Actually I don't like how these apps work. And I thought that setting up a few parameters would't be difficult. It seems I was wrong.
Yep. Code has to execute to do stuff, otherwise that stuff doesn't get done.
System Tuner Pro allows voltage adjustments on overclock settings. If you're interested. Also, has a lot of packages integrated into one (task manager, app freezer, etc). They have a free version in the Market if you're interested. It's nice to have several apps, in one nice package.

Thank you but I actually don't need it anymore
I have rolled back to the stock kernel because of constant "sleep of death" issue.

It's because the 3.7 kernel you used, is really not compatible with the a501. The ultra-low voltage causes "screen freeze" and the "sleep of death" when under 3g only. It's a known issue with the 501 and 3.6 and 3.7 kernels also. I would reccommend RTrips 3.4+. Probably his best for for a501.
I ship it with my own Alexandra II and III rom. No issues with it, and none ever reported.
Had I noticed when I woke this morning, you had an a501, I could have given this advice. Sorry, didn't have enough coffee

The problem, is that a lot of dev's, don't have a501's, only a500's. So they really can't test a lot on it. And sometimes, the issue doesn't happen for 2 or 3 days. Sometimes less. I'm going to experiment a little this weekend, with some of the newer kernels, and mess with the voltage's and see if I can get it stabilized where it doesn't freeze on 3g only.
Moscow Desire ,
Thanks for clearing it up and the advise. I'll try either 3.4 kernel or your ROM.

If you go to RichardTrips kernel thread, you will see a link to his older kernels.
You will find the 3.4 listed on his server. I think you just need to flash it, although I usually dump Dalvak cache.
Alex II is an easy install. Alex III (3.2.1) is a little more ... interesting to install, but not difficult. If you run into an issue, post it in my thread. Everybody else has got it installed, so I think you'll have no issues either.
It's the only "certified" 3.2.1 for the Acer a501 that I know if. Not that the other roms are bad, because they really are good, but, the 3.2.1 they advertise, are from system dumps after running an update, or adding missing files to a 500 rom. The TMPL is an Acer release.
Like the title says, I was just wondering if there was a way to change the default CPU speed on boot permanently? I know I can use SetCPU, but sometimes that hasn't held through a boot and I had to set the speed manually. So, I was hoping there was just some script somewhere I would have to change. But then I got to wondering, would that be possible from my phone? Would I have to build my own kernel? Or would I just be able to decompile the rom in dsixda's kitchen to change a kernel script? Any help is greatly appreciated!
I use ROM Toolbox. It has a ton of stuff including CPU Control and CPU Profiles (like to make it 691MHz max when the screen is off). And you get a lot of other stuff with ROM Toolbox. But you could say the CPU part is like Set CPU. Don't really know if this answered your question. Hope I helped though.
I'm pretty sure CM7 has a built in CPU setting feature in its Cyanogenmod Settings -> Performance menu. It gives you the option to set on boot as well. I've never played around with it so I'm not sure if it'll give you the same problems you're describing now, but it's worth a shot if you don't want the separate app.
Is your phone rooted?

I need maximum battery time. So what is the best kernel for this and it´s configuration? I don´t need answers like "search for it" . Go hell those stupid guys.

there is no such thing as perfect kernel or perfect configuration,
the factors that can determine the amount of battery usage depends heavily on the nature of the usage under the user itself,
most kernels with undervolt support and underclocking will do fine,
i'd suggest you try out tweaks and preferences yourself since no one can guarantee you an exact time frame,
but i'll give you mine,
ROM: WP8 Monochromatic 5.1
Kernel: Built-in rom (savie's)
Tweaks: Built-in rom
Scaling freq: 156min 624max
CPU Governor: ondemandx
reduced all bloatwares even gmail and maps,
Battery Time (heavy usage): 4hrs max (medium usage): 1-1.5 day max (minimal usage) 2-3days max
that's just about it,
please take the time to conduct a research on what is your best prefered battery saving method,
don't call anyone stupid,
it's bad and potato disapproves
Rom doesnt matter really if you manage the applications well.
Use kuros kernel + kuros tweaks. Thats the best battery saving combo Ive tried.
For governor, use ondemand, the most battery efficient governor and use deadline for i/o

Not really. Change between Merruk #206 and kuros latest, you can really notice the battery drain difference. Its battery efficient than stock kernel in my tests.
Here u go:
Before all id reccomend updating the software to the latest version xD
Use the latest white kernel
Use v6 supercharger and some other tweaks
Reduce the screen brightness
Lower the system volume in the sounds options
Disable animation
Disable auto-sync
Disable backup settings
Disable roaming ^^,wifi,mobile internet,bluetooth when you dont use it(gps even if turned on allways is only actually active when theres a open app that uses gps ^^)
Disabling more sound effects will make it ugly and not cool lol,so do as u wish with thease:
Keyboard sounds
Lock screen sounds and vibration
set a boot frequency in set cpu like:
312-832,conservative,sio
Set up proper profiles in set cpu like
Screen off
312-312,powersave,noop
Charging
312-832,ondemand,sio
Battery 50 F
312-832, conservative,noop
Battery <16
312-832, conservative, noop
here just take my setcpu profiles, i made it in setcpu 3.07 just put it in the root of your sdcard and in setcpu enable profiles and click on restore profiles and click on that

Here are some build.prop tweaks
ro.ril.power.collapse=0
ro.ril.disable.power.collapse=0
dalvik.vm.heapstartsize=4
dalvik.vm.startheapsize=4
this one is alredy in v6 supercharger ;P
pm.sleepmode=1
remove some useless apps that u dont use but their allways running in the background(yeah remove anything u will never use)
Google maps
email(not gmail)
software update
and buying a new, better battery isnt a bad idea too ? is it (obviously xD)
I hope i Helped, this and some of my other build.prop tweaks made my battery go like lol xD it was lasting so long idk how much was it
Thank you all! Thanks so much guys!:good:

the correct one is "dalvik.vm.heapstartsize". dalvik.vm.startheapsize is not exist. nevertheless, this script only work for ICS. GB based rom doesnt have these prop. please be carefull with any prop for virtual memory like this one. if you clean your dalvik-cache you might ended up in bootloop.
Lots of information.

Hi guys,
Sharing with you'll few kernel tweaks that will betterment your battery backup and also maintain good performance on the default kernel of CM13 ROM and it's variants.
Won't bore you'll with lengthy description Head on straight to my screenshots and tweak accordingly.
These have resulted me with less drain in foreground usage and more solid backup in standby.
Thanks to you sir for writing this up! I'm going to try these settings on stock, just to
see if it'll work. If they do I'll let you know. May I ask you why you have set the minimum frequency higher?
EDIT:
The settings won't stick, not even through standby. Oh well. One probably needs a custom ROM then.

Yes CM13 or its variants.
Stock ROM kernel is good by itself. In stock you can try only change IO Scheduler as deadline.
Edit: one small change in TARGET LOADS uploaded in last screenshot
Just downloaded the latest version of franco kernel manager 6.1. Im a total noob in terms of using this tool, so I've been looking for a guide or a tutorial that can assist in using it. Also what is the method of flashing the franco kernel from this tool? Where can I download the franco kernel.zip? I have been looking all over, cant seem to find it. Plz help
Im currently on RR Rom latest version 8.6.3. Im looking for a setting to enhance battery life and overall performance of the Phone.

Hey there
What I did to get Franco kernel was flash it during my first time rooting (so it was a clean flash, as the phone had be factory reset). Once you're in TWRP, you flash Franco kernel and then magisk. This is one way to do it. I can't advise you to flash a new kernel without clean flash because I personally didn't do it and I don't know if issues will come from that. If you can do it, my personal advice is to just do a clean flash. You know the drill, wipe system data and that stuff > flash ROM > Kernel > Magisk, and done
As for where you can get the zip, there is a thread here in the OP5 XDA forum on ROMs and Kernels I think and that's where franco posted the kernels. He's got a website too linked in the same post
HOWEVER, he hasn't updated them since last year, and I don't think they have support for Android 10, only 9
As for settings, well, in my own experience, you won't get any noticeable boost in battery life or performance without doing some drastic change.
If you want better battery life, you can decrease the maximum CPU frequency, change the governor to Conservative or Powersave, disable some cores, or all of those at once, but they WILL degrade performance, sometimes you won't notice but then you'll try to load a heavy webpage on Chrome and then you'll REALLY notice it.
The inverse is also true. To increase performance you change the governor to performance; usually the CPU frequency is set to its maximum by default, and the cores are all enabled anyway so you don't have to change anything. BUT, keeping the governor in Performance will also keep the CPU clocks at its maximum, and that's going to drain your battery like CRAZY, plus it'll overheat it. Usually there is no practical need for this setting, but I use it to play games on Dolphin emulator since thats when I can actually make use of that performance.
A better alternative is to keep the governor on Interactive, which will scale up CPU clocks depending on the load (if doing light stuff, low clocks. Heavy stuff > high clocks). Otherwise, Conservative does the same thing but takes longer to use higher clocks, so battery is saved.
Always use 1 governor for all cores. Do NOT use multiple governors (example: powersave for big cores, performance for little cores) because that will cause instability issues
Also, if you make any changes, you gotta tap the toggle on it, which will say something like "stay on boot: true". Otherwise, if you for instance change your governor to Performance, and then reboot, all your changes will reset to Default
Personally I just keep my governor in Conservative and roll with the defaults.
Hope that helps ya
sorry for digging but I was loooking for solution..
just make a backup of present kernel (tuned with FKM) and then flash it from backup menu
I was trying flash with twrp, magisk, 'set on boot' at first and many other things but it was so simple, it's there all the time
