It works but...

Hi! Thanks a lot, seeder makes my Nexus 7 and my Ace fly!

But, I am having some troubles..

1. I have installed the .apk posted in the 1st post, and it works greatly in my ace but when i put

su

watch -n 1 cat /proc/sys/kernel/random/entropy_avail

on terminal emulator, it shows

Every 1s: cat /proc/sys/kernel/ra.. blabla and nothing more. Anyway, Seeder says that is working.

2. On my nexus 7, i have installed the same that in my Ace and when i go out of seeder and i turn back, it always says Off, but when i go to terminal emulator it shows me a number above +3900

3. Oh, and i have seen a v5 version of seeder flashable by CWM but when i try to install it CWM returns an error code (0) and says "Installation Aborted"

Thanks a lot! And the tipical "sorry for my bad english :laugh:"

I really like the idea, I was wondering about this common issue on android devices... well you have figure out one of the reasons!! Good job.

Installed it on a Defy+, after a reboot + 2-3 minutes, the device has less lag! Thank you!! :victory:

I am available, If you need any help for the app (testing,dev or whatever)! :highfive:

can i use this with stock , rooted 4.2.1 galaxy nexus ? stock kernel. just by installing the app ? is see 3 files in download section. which one should i use ?
[Android Software/Hacking General [Developers Only]] MrFrem82:
I'm tryng to install V5.zip on a Galaxy 5 CM7, but installation abort all the time. I've also changed update-binary with some others that works on this phone, any suggestion?

I take .zip from here, http://www.androidfilehost.com/?fid=9390248398092763238

You need a rooted device, that's it
[Android Software/Hacking General [Developers Only]] Tungstwenty:
Here's a quick way to test if the lack of entropy (whatever the available value is) produces lag or not, WITHOUT having a process running each second - to increase entropy or to measure it - which some might argue might affect the CPU throttling:

- boot normally without any /dev/random modification active

- use if for a while to "let it settle" and get the feeling of the speed

- in a terminal or adb shell, temporarily point the /dev/random device to /dev/urandom, which doesn't block at all:

su
mv /dev/random /dev/random_ori; ln -s /dev/urandom /dev/random

- use it from then on for a while and see if it makes any real difference

- after testing, simply reboot the device to have everything as before or run this in the terminal:

su
rm /dev/random; mv /dev/random_ori /dev/random

With the symbolic link there will be no active code feeding entropy into the "random" device and all consumers will be reading from "urandom" instead without any lag.

I don't know whether the code using random data will validate if it's random enough and potentially spending more time calculating random stuff until it's good enough for e.g. SSL, though, so you'll need to interpret the outcome with a grain of salt...
[Android Software/Hacking General [Developers Only]] yodanutz01:
which files should i use ? there are 3 in download section
[Android Software/Hacking General [Developers Only]] jordi6294:
The 2nd one.. just install it like a normal apk and that's all!:good:
[Android Software/Hacking General [Developers Only]] adelancker:
So I can just download the .zip from the OP and flash it through TWRP?

Or am I wrong?

And do I need to wipe cache and data or should I do anything else too?
[Android Software/Hacking General [Developers Only]] dzltron:
Just use the .apk, wiping cache and data will do nothing.
[Android Software/Hacking General [Developers Only]] alkhemista:

[Android Software/Hacking General [Developers Only]] nhariamine:
How to install it ? there is three files in down section, the OP should write a how to install point...:confused:
[Android Software/Hacking General [Developers Only]] Ryuinferno:
Ahh...that explains why I failed when I tried using the ln command, we must actually "delete" /dev/random, then only it is possible to symlink /dev/random to /dev/urandom...will do this as a init.d script...:)

I experimented using the symlink method and the entropy generator...here are my results:

Symlinking /dev/random to /dev/urandom:

Using the entropy_watch binary by zepplinrox, my entropy value is constantly at 3000++, it goes down but gets filled up again after around 2 seconds...

Using the entropy generator:

I get values around 4000++, once it goes down, it immediately shoots up to 4000++ again...the generator does not leave space for entropy to go down...:p

However, the improvement in performance does not differ too much (or maybe no difference at all for me)...but theoretically symlinking should be more battery friendly when compared to rngd which keeps on running as a process...:o...not sure about this, needs more testing...
[Android Software/Hacking General [Developers Only]] spewak:
Purchased the app in the Play store.

Very nicely done. Apps are snappier.

I will let you know if I experience battery drain that is faster than normal.
[Android Software/Hacking General [Developers Only]] Exit_Only:
You can use seeder if you disable qrngd binary!
[Android Software/Hacking General [Developers Only]] Ofthecats:
You mean it works better that way?

I'm running seeder on 1+1 slimsaber caf, ak kernel. I'm unsure how much it improves things.
[Android Software/Hacking General [Developers Only]] moonryder:
and how can i do that?

btw my device has a snapdragon cpu with qrngd binary, but after installing seeder 2.0 i got a message that qrngd is running. i enabled Seeder and nevertheless it works (without disabling qrngd). And now?

Another question at this place:

A working selinux is kernel related?
[Android Software/Hacking General [Developers Only]] Exit_Only:
No seeder isnt working! Its qrngd working restoring your entropy nativity!

Type in terminal

su

killall -9 qrngd

mv -f /bin/qrngd /bin/qrngd.bak

SELinux is built into the kernel! Are you wanting to turn ENFORCING to PERMISSIVE?
[Android Software/Hacking General [Developers Only]] Ofthecats:
Is seeder better than native snap dragon entropy
[Android Software/Hacking General [Developers Only]] moonryder:
hi Exit_Only,

i renamed /system/bin/qrngd with Root Explorer to qrngd.bak, it´s the same like your command in terminal.

And YES i want to turn enforcing to permissive
[Android Software/Hacking General [Developers Only]] edzamber:
Hi,

Is there a way to active seeder directly in Rom without use terminal emulator ?

Many thanks.
[Android Software/Hacking General [Developers Only]] steviedhadi:
hi guys want to ask simple question from nubie. i used xperia z3 rooted. i already using seeder for several months, runs good on my device. but, today, suddenly seeder apps always force closed. i try wipe data n open the app again, still the same. force close. i uninstall, reboot the phone, n instal it again, same result. force close. i use seeder 2.0 apk from xda. someone share paid version. do this mean my apps have been detected by seeder developer team and send crash file to my seeder aps? or something else wrong? thx if someone answering my question.....

Best Regards

[Android Software/Hacking General [Developers Only]] Rhoban:
Paget96, creator of L Speed Mod, said the the rngd service may not work on newer android devices. I don't know if it is true or not.

The app runs well on my S4 with AOSP Marshmallow rom.

the best rooted app
[Android Software/Hacking General [Developers Only]] Dawidus520:
Amazing app. Works on all my devices (almost). I have problem with one mobile phone. S7560 Galaxy Trend. CM11 installed, rooted, twrp installed, everything works, terminal gives back "#" when i wrote "su" but app stil says "Seeder can't start RNGD service, this happens when your device in's rooted.. bla bla". Can't figure out what causes this error, tried to install varius versions of CM11 and even CM 10.2 but result was the same. Is this phone constructed with non-lagfree feature? :laugh: Anyway, any help will be appreciated, this app gives back some smoothness on "****ty" phones :)
[Android Software/Hacking General [Developers Only]] dhruvpaul:
Will that cause any harm??
[Android Software/Hacking General [Developers Only]] BatDroid:
A Q

Is it still on developing state?

or

Dev just thrown it away?

---------- Post added at 12:46 AM ---------- Previous post was at 12:42 AM ----------

Do u have installed any tweak like crossbred or something??

check out ur system /etc/init.d

some tweak have pre-installed seeder binary and don't let seeder to get started.

I used cm 10 to 12.

There wasn't any problem.
[Android Software/Hacking General [Developers Only]] Dawidus520:
No I don't installed anything else. But this happen even after fresh installation of rom. I mean, i Install rom, even don't install gapps, only SuperSU, and go straight into filemanager to install seeder, i open it and bam, happens this what I described before. On any other phone, seeder works both ways (fast installation of rom without Gapps, only with SuperSU, or normal one, with all what I need), but on Galaxy Trend, it doesn't.
[Android Software/Hacking General [Developers Only]] BatDroid:
then its a problem with root access may.

Is ur root okay?

I mean su binary?
[Android Software/Hacking General [Developers Only]] canodroid15:
Seeder won't work with the new "systemless root" unless kernel is set to permissive. Are you using systemless root?
[Android Software/Hacking General [Developers Only]] Dawidus520:
[MENTION=7017727]Dark Knight Begins[/MENTION], Yes it is. [MENTION=5806583]canodroid15[/MENTION] What do You mean exactly? If i understand properly, you mean that I flashed SuperSU via recovery? So Yes i did, but I'm doing it always on every phone and i don't have any problems. And on this phone kernel is set to enforcing but even if I change it to permissive (via KernelAdiutor), seeder still don't work.

Nice, keep seeder thread active, but somehow it doesn't work on newer device or older devices?,, for users with JB rom and below just use the script method.. Time to wake up randoms, keep the cpu active.. Single core device would work flawlessly alongside the script..

Thanks dev
[Android Software/Hacking General [Developers Only]] Kam0laZ:
Hmm ... I'm running a Sony Xperia M4 Aqua, an E2303, running AOSGP 2.0 rom on 26.1.A.3.111 firmware (Lollipop 5.0).

According to Sony website, this phone has a "64-bit Qualcomm Snapdragon 615 Octa Core processor (Quad-core 1.5 GHz + Quad core 1.0 GHz)"

I installed Seeder 2.0.0 apk version from this thread.

Before turning it on, the phone entropy was 1000~1500. After turning it on, the phone entropy is 3000~4096.

Seeder is working ... right? On my phone's Snapdragon processor ... right?
[Android Software/Hacking General [Developers Only]] keithross39:
It would appear to be adding entropy.....though the benefits of this increased entropy on a quad or octacore snapdragon device will probably be fairly marginal in terms of performance. Don't forget that Seeder was written at a time when single or dual core devices were the norm.....where additional entropy was really needed (no disrespect to the developer intended)......

Galaxy Ace S5830

Tried all the performance scripts (Seeder, Crossbreeder, fly on mod, Killjoy) on Mardon's CM10.2 [stable-20140309 version] ROM (including as well Pure Performance and excepting SuperchargerV6 based on Mardon's comment to Viper The Ripper). All but Seeder created issues with Apex launcher, additional lags, etc. etc.. Best combination so far I've found for this particular ROM: Root Booster (free version on Google Play Store) and Seeder (zip from XDA - free). Seem to work well together to increase performance, smoothness with better stability. Thank you lambgx02, and Ryuinferno ... very much appreciated. Cheers, S.

Root-issue :(

Hello,

sadly Seeder does not work for me, it always says it could not start the RNG-Service.

"Seeder was unable to start the RNG service. This usually happens if your device is not rooted, or if Seeder has been denied root privileges.

Check your superuser and/or su binary installation, or try restarting your device." :(

1.) Restartet the device multiple times

2.) Seeder has root permission

3.) No other application on my device has root problems

Galaxy Alpha (SM-G850F)

[Android Software/Hacking General [Developers Only]] Genesius01:
Is your kernel enforcing or permissive? I've never been able to get Seeder to work with an enforcing kernel.
[Android Software/Hacking General [Developers Only]] JellyShakers:
Are you referring to SELinux-Status ? It's "strict", which I think is the same as "enforcing" ?

EDIT: Changed SELinux status to "moderate" (permissive) with console command "su" and "setenforce 0".

Seeder is working now! However disabling SELinux ist not good :(

Any way we can fix the SELinux context for Seeder so it still works in enforcing mode ?
[Android Software/Hacking General [Developers Only]] sohojmanush:
what about seeder in marshmallow doze mode? will it work or needed some tweaking?

[Android Software/Hacking General [Developers Only]] chuaj6363:
Not working

I am running CM13 [latest nightly] on my Redmi 2 and Seeder will keep complaining that the SU binary is not properly installed... My phone is rooted tho. Help pls:eek:
[Android Software/Hacking General [Developers Only]] Dawidus520:
Well, common bug, I had this error on Galaxy Trend with CM11. If you need seeder option, you can use for eg. L Speed. It also includes seeder entropy. And also many more optimization functions. No it's not an ad, just recommending it from my experience after I had this bug.

Maybe it's placebo effect, but every phone that I used seeder on, was faster ;)
[Android Software/Hacking General [Developers Only]] ruchern:
Same problem here. Are you on CF SuperSU 2.78 SR4?

---------- Post added at 11:11 PM ---------- Previous post was at 11:09 PM ----------

L Speed doesn't even request for SU and immediately throws an error saying that Root is required.
[Android Software/Hacking General [Developers Only]] Dawidus520:
In this case probably there are two options.

First one is that you haven't enabled root in dev options.

Second one is you're just not rooted.

Is any other app shows similar messages? Check your root status using root checker app or something. And try rooting again using SuperSU zip.
[Android Software/Hacking General [Developers Only]] ruchern:
I'm running Titanium Backup abd it's working fine. How can i not be rooted?
[Android Software/Hacking General [Developers Only]] RReddington:
Same problem for me with OP3 CM13, device rooted, any other pb with app needed root :

"Seeder was unable to start the RNG service. This usually happens if your device is not rooted, or if Seeder has been denied root privileges.

Check your superuser and/or su binary installation, or try restarting your device."

Seeder as bug with new su?
[Android Software/Hacking General [Developers Only]] Dawidus520:
Probably it's related to new systemless root method which didn't existed while Seeder app has come. And simply it don't recognize this way, so app thinks that there is no root/su binary. Switch to other app.
[Android Software/Hacking General [Developers Only]] ruchern:
I am still not getting it to work on SuperSU 2.79 SR1
[Android Software/Hacking General [Developers Only]] canodroid15:
Are you running in permissive? You have to be running in permissive mode with systemless root & it might say it failed anyway but look at the entropy level. If its full it working despite the message that it failed. Also, you may have to open the app & hit the on switch after each reboot or power cycle.
[Android Software/Hacking General [Developers Only]] ruchern:
I am running Permissive and with SuperSU Systemless Root. It's says failed when I press the on button. But with aggressive I do get 4096 entropy levels.
[Android Software/Hacking General [Developers Only]] canodroid15:
Then its working :good:
[Android Software/Hacking General [Developers Only]] Daman5202:
Hey, im using kernel adiutor to manage entropy levels! Do I still need this app? Heres the kernel adiutor screenshot :
[Android Software/Hacking General [Developers Only]] MihaiSG:
No, this feature of Kernel Adiutor does the same thing.
[Android Software/Hacking General [Developers Only]] ruchern:
Seemed like the development for this app is over. :(
[Android Software/Hacking General [Developers Only]] Namoi:
But if you use for instance kernel adiutor and a kernel exposing entropy parameters you can tweak this without the need of this app which is also probably why it isn't developed anymore as it was superseded by kernel tweaking app.
[Android Software/Hacking General [Developers Only]] asusgarb:
I have always used this app on every device because it works without consuming too much battery. Now on my tablet I flashed Lineage 14.1 and seeder doesn't work (I suppose because of systemless root). I even use L-Speed, but it's seeder works good only in aggressive mode, but so battery dies too fast. I think even kernel adiutor setting could cause the same, because let entropy 4096 all the time.

Is there something we can do to have seeder without killing battery?
[Android Software/Hacking General [Developers Only]] jc9896:
Doesn't seem to work on CM13... Says that service can't start.

Using cmSU (stock CyanogenMod root)
[Android Software/Hacking General [Developers Only]] MihaiSG:
For me on CM13 and SuperSu Seeder is working fine.
[Android Software/Hacking General [Developers Only]] asusgarb:
I have 2 devices with Unofficial LineageOS 7.1.1, and in one Seeder works as expected, in the other i have the same error.

Now one question. I set entropy (both read and write) to 4096 with Kernel Adiutor, but battery drains faster then with seeder (i tried also where seeder is working).

I know that development has stopped, but i want to upload 2 logcats taken from both my devices. Maybe someone can understand the problem and suggest a solution.

Updated Seeder app for newer Android Versions

I hope I have not broken any laws or XDA rules, or antagonised anyone because of decompiling and recompiling an app, I honestly did all of this with good intentions and only modified the code that are no longer working. If I have broken any laws/rules please tell me I'll delete this post and the above post. I did NOT inject malicious code or viruses into the app or do this so as for commercial purposes. If you do not trust me because I'm not the original developer(I understand), feel free to edit the app yourself, who knows you might find better solutions :) If you don't mind share your solutions with us here! For details on what is wrong in newer Android versions look here Credits to [MENTION=1107425]lambgx02[/MENTION] for making this amazing app, I am seriously a newbie to Android development and cannot have written something anywhere close to this good. All I have done is update snipplets of his code to work in newer Android versions, I have no part in writing any code in this app. And with all due respect [MENTION=1107425]lambgx02[/MENTION] I also mean no offence in writing/doing all this, I am not calling your app outdated or you a lousy developer, all this is because of updates to Android's security framework which in no way is your fault, and this app is really amazing and useful as many others have said. Thank you so much for this app ^_^

Note: This app is signed with a different signature(because I obviously do not have lambgx02's developer signature) so you will have to uninstall any versions of Seeder that you already have. But don't worry you won't lose anything if you uninstall Seeder and install this, just configure Seeder again to your preferences :)
[Android Software/Hacking General [Developers Only]] lambgx02:
Actually I greatly appreciate it. Unfortunately my life changed pretty dramatically in the past few years (for the better, haha) and I don't have any free time at all these days. The fact you can keep Seeder useful for others on modern versions of Android is fantastic, and frankly if you want the source just PM me.

I can put a link to your builds up in the first post when you're ready.
[Android Software/Hacking General [Developers Only]] haoyangw:
Oh congratulations on the positive changes to your life haha, my best regards and all the best :) Thank you for your understanding and support too! I don't mind helping to maintain and update this app haha, I'll PM you in greater detail and discuss about this
