[Galaxy S I9000 Android Development] zenkinz:
most if not all A-GPS implementation in mobile phones make use of pre-determined (through algorithm) orbit path of the satellites (otherwise known as ephemeris data) to triangulate the position. This information takes roughly 30sec per satellite to download if through directly from Satellite, although they can be received concurrently. However, every interruption of signal (block by buildings, tree canopy, etc) result in the whole transfer process repeated again. Today's A-GPS implementation, unlike the earlier days where assistance servers are used to offload the triangulation process, offer the availability of the ephemeris data in advance through internet, eliminating the potential delay in the triangular process. The added advantage is the data has a lifespan of 5-7 days, versus 4 hours if getting it directly from Satellite. The result is fewer 'cold start' situation but as the age of the downloaded ephemeris gets older, the accuracy of the triangulation process gets lower as well.

I am sure you know all these, or maybe have different opinions. But my point is you can still get a location fix with APN or WIFI turned off, because the ephemeris would have downloaded way before.

Otherwie, I agree that getting a fix in a farmland, even indoor, makes alot of difference as compared to getting a fix in a building/apartment.

PS: If we want to discuss this further, maybe a new thread is in order. I digress.
[Galaxy S I9000 Android Development] zenkinz:
v1.50 update available!
[Galaxy S I9000 Android Development] r4stafari:
cwm version for 1.50?
[Galaxy S I9000 Android Development] manageri21:
A CWM version can you?
[Galaxy S I9000 Android Development] elhpianist:
Thank you!!! feels very very smoooth like a 500hz version of Speedmod, but without the excess battery drain under usage.
[Galaxy S I9000 Android Development] zenkinz:
uploaded. please refer to download history for the link.
[Galaxy S I9000 Android Development] musume:
Good Job zenkinz.... d^_^b

How do I overclock the phone? Is it already done in the kernel?
[Galaxy S I9000 Android Development] zenkinz:
OC (Overclocking) & UV (Under volt) are pre defined in YA-OK kernel.

To the rest, please feedback the stability of new OC value (1.12Ghz).
[Galaxy S I9000 Android Development] likepeas:
Alright cool, anyway I actually had a bootanimation before flashing the new 1.50update via odin and now the bootanimation is gone.
[Galaxy S I9000 Android Development] elhpianist:
YA-OK has never had boot animation support..which kernel were you coming from? Hardcore's speedmod?
[Galaxy S I9000 Android Development] likepeas:
XWJPA asian version, then on YA-OK 1.49 then to insanity which had bootanimation and now upgrading to 1.50 which losses the bootanimation.
[Galaxy S I9000 Android Development] tokyogtr:
what did the bootanimation look like? also, there is no 1.49 YA-OK.
[Galaxy S I9000 Android Development] bboyspyder:
Any big performance difference between 1.12 and 1.2 ghz?
[Galaxy S I9000 Android Development] likepeas:
it was the bootanimation from the insanity rom.
[Galaxy S I9000 Android Development] tokyogtr:
then you were not using YA-OK, you were using superoptimized or speed mod.
[Galaxy S I9000 Android Development] likepeas:
I'm rather sure that I was using YA-OK. How would I actually check what ROM I'm running on right now.
[Galaxy S I9000 Android Development] tokyogtr:
settings - about phone. i guarantee you were not using ya-ok and seeing the insanity bootanimation.
[Galaxy S I9000 Android Development] brack11:
Ok first GPS lock with 1.50 took about 3 minutes which is longer than with speedmod but everyone chooses features that he needs most and I choose battery life over GPS. Thank you for kernel.
[Galaxy S I9000 Android Development] elhpianist:
To check if you're using YA-OK! kernel go to settings, about phone, kernel version:

the kernel version should read something like:

2.6.32.9 zenkinz@kernelcomplier #38

and Ya-OK does not have boot animation in any of the builds.
[Galaxy S I9000 Android Development] jogefo:
how does 1.5 compare to k10i ? I got k10i at the moment and thinking of going back to here
[Galaxy S I9000 Android Development] do-shaq:
@jogefo 1.5 is way better than k10i i've tried them both and i found that 1.5 is a lot faster and more responsive and have less battery drain with all tweaks on and with ext.4 ALL, so i stick with Ya-ok for a while
[Galaxy S I9000 Android Development] emirytr:
you can not optimized this kernel to 1.5ghz. I need this. I have now 1.2ghz with your ya-ok v140. but I need more speed. it is not possible to optimize this kernel?
[Galaxy S I9000 Android Development] elhpianist:
Do you want to burn your phone or something? If you want speed buy a ferrari.
[Galaxy S I9000 Android Development] tokyogtr:
zenkinz, great job with 1.50. even smoother than 1.45. so i guess upping the cpu speed is fairly pointless in the bigger picture. refinements to memory and i/o seem to make much more difference.

keep up the good work!
[Galaxy S I9000 Android Development] emirytr:
I think that this mobile have more potential to go more fast. I use it all time on 1.2ghz. not hot and work fast. I ask only he can optimize it to 1.5ghz 1.6ghz for me..
[Galaxy S I9000 Android Development] jogefo:
If anyone can tell me, I guess same as before I can flash directly 1.5 without disabling lagfix. I got K10i speedmod currently. thx

Update: Just flashed over, works fine so far, will post further after testing
[Galaxy S I9000 Android Development] alimur_r:
what about the quadrant score using the latest 1.50 kernel???
[Galaxy S I9000 Android Development] boris03:
Ok now I would like to give it a try

So I think to reset the ROM to Doc´s JP8 v901 (because I think the JP6 is not yet really stable, correct?) and would like to flash

the v1.5 kernel on top.

Currently I am using Docs JP8 v9 with all tweaks but no lagfix enabled.

So how to do that the right way?

I have read so many things with deleting Dalvik and ...

Is there an explanation step by step or something I could use?

P.S. and what is the right lagfix option - there are so many!

Thanks a lot

boris03
[Galaxy S I9000 Android Development] manageri21:
feedback

for me with this OC is more stable on the score of quadrant and linpack always near the same point, any problem with rockplay software mode and hardware mode.

for 1.2Ghz you put again on next release?
[Galaxy S I9000 Android Development] manageri21:

not to offend you but:

are you crazy ? :eek:

that way

*) your battery will drain in no time

*) the possibility that your device blows up against your ear is way higher (http://dvice.com/archives/2010/12/motorola-droid-3.php)

*) you'll lose your guarantee (you have already - but that way for sure)

*) it'll overheat and burn your hand - or start burning literally

...

back to topic:

thanks for 1.5 ! :)
[Galaxy S I9000 Android Development] zoubidou:
yes you can flash it directly with cwm.

quadrant = 2058 about 100 less then 1.45

not to say it is nothing. and everything is smooth and fine.

just for the ones who had a problem with the gingerbread keyboard.

it has nothing to do with the Kernel. check in cwm mounts, and mount /system if it states "mount"

after use cwm for installation and everything is ok.

i still have the problem: mount: mounting /dev/block/stl9 on /system failed:

device or ressource is busy.

I think thats the reason way mine takes at least a minute to start.
[Galaxy S I9000 Android Development] littlejax:
Zenkin.. Can you do a version for 1.2ghz for 1.5? much appreciated

THanks~!~
[Galaxy S I9000 Android Development] bboyspyder:
Can I somehow change /system to ext4 with this kernel or I need to install voodoo kernel first so I make it ext4 and then this, because all other on this is blazing fast.
[Galaxy S I9000 Android Development] Astug:

[Galaxy S I9000 Android Development] wcg707:
My questions are:

1. What are the built-in optimization/lagfix/tweaks that comes with this kernel 1.50, without enabling/installing Voodoo or ULK?

2. Does this kernel still using the ramzswap /compcache or it has being disable?

3. What is the recommended filesystem lagfix for 1.50?

thank you
[Galaxy S I9000 Android Development] alimur_r:
thats good enough...

also the score can be increase with the upcoming Doc rom XXJPU...

heard that is more faster than ever...
[Galaxy S I9000 Android Development] Bara2:
Will probably not work atm. We'll have to wait for zenkinz and the next version :)

are we still have corupted file system??

i run Spiky rom v.4,i dont now what kernal is implemented

under kernal stay zenkins#kernalcompilir#31
[Galaxy S I9000 Android Development] betoNL:
Testing right now.

Some good news for all and some bad news for me.

Good news:

1)It's fast, responsive 1100 quadrant (no lafix)

2)The "Kernel Scheduler parameter" thing , does have an impact on gps performance or

that's something to do with the Hz and voltage thing...why? For the first time I got a satellite lock INDOORS just by staying close to the window

and no FULL A-gps (supl). never happened before

The bad news (for me):

Instability when running iGo Motonav (freezes)..something with the voltage settings I guess....still trying... perhaps could try using xan's apk., just dont know...
[Galaxy S I9000 Android Development] manageri21:
i download the firmware but i wanna wait the developer for slim firmware like doc or insanity,

and certainly the kernel

we hope soon
[Galaxy S I9000 Android Development] brack11:
Wow, gps indoors!!! Naa, you must be using a-gps... Never mind, just welcome to the club. And as I mentioned before, I don't think kernel tweaks improved gps in 1.5, speedmod must have something else.
[Galaxy S I9000 Android Development] brack11:
Are there any plans to support jpu?
[Galaxy S I9000 Android Development] betoNL:
Indoors, c-l-o-s-e to the window.

Never happend before with the sgs, only with my sirfstar3 equipped devices...

Therefore the scheduler tweak that gives the gps process, more processing time, must be working.....
[Galaxy S I9000 Android Development] Virnik0:
+1 to that question, I am interested in it too.

Second thing is, do this kernel support boot animation? What about BLN? What about TUN module?
[Galaxy S I9000 Android Development] -NRG-:
No, no custom boot animations are supported. BLN is possible trough clock work mod which is included. Don't know about TUN module..
[Galaxy S I9000 Android Development] lifelessfreak:
Hey, i got a stupid quest. What do u mean by OC in ur changelog? If i install or flash this kernal, it would be automatically OC'ed? Or i've to enable it manually?

Edit : I meant Overclocking.
[Galaxy S I9000 Android Development] jsen:
automatic..all is preset in YA-OK ;)
[Galaxy S I9000 Android Development] wcg707:
YA-OK inbuilt overclocking is giving me plenty of error message "[PWR] set_gpio_dvs" every 1-2 seconds from dmesg or OSMonitor.

I suspected it was some other apps spewing this message but after replacing it with SpeedMod, the error messages no longer there. After running a test on 10i 500mhz with ext4 lagfix, I think YA-OK still rock except for those messages above which I think is coming from the oc.
[Galaxy S I9000 Android Development] Angelos1979:
is the ya-ok v1.50 kernel compatible with the new xxjpu firmware?
[Galaxy S I9000 Android Development] g00ndu:
No....
[Galaxy S I9000 Android Development] Robyj80:
;) boot animation

This is kernel support boot animation?
[Galaxy S I9000 Android Development] elhpianist:
No again, please read the first posts of all threads..99% of the time it be there, if its not, look at the 2nd post ;)
[Galaxy S I9000 Android Development] zenkinz:
bootanimation should be available in next release, many thanks to hardcore for his willingness to share his initramfs with me.
[Galaxy S I9000 Android Development] zenkinz:
most likely caused by the OC, rather than UV. to verify, use setcpu to limit cpu frequency to 1GHz, and see if your iGo still fails.

in some cases, restarting and rerunning the offending app (at the same freq, but after reboot obviously) might be okay.
[Galaxy S I9000 Android Development] lifelessfreak:
Cool! Thanks!
[Galaxy S I9000 Android Development] azizmulhim:
When it is possible to have OC user configurable instead of using setcpu application.

Another question, which is more stable version 1.2b or the latest kernel.

appreciate if someone can answer these questions.
[Galaxy S I9000 Android Development] lifelessfreak:
Does anyone faced any probs with this kernal?
[Galaxy S I9000 Android Development] wcg707:
What problem would that be? I was using this before going to Speedmod and now to XXJPU. There was no problem with YA-OK.
[Galaxy S I9000 Android Development] betoNL:
Was facing instability (freezes)

Didnt happen with Trasig's kernel using same OC: 1.12Mhz

Stopped testing it because I was to curious to try Stock JPU

JPU looking good!

IMHO the only optimized kernel that would beat stock JPU, would be a Optimized(even more) JPU
[Galaxy S I9000 Android Development] nabilfareez:
wat lagfix setting will be nice for this kernel in da lagfix options?
[Galaxy S I9000 Android Development] elhpianist:
Been using this kernel since build #23, never a problem, each update gets better! its one of the best available, if not THE best for my needs and usage :)
[Galaxy S I9000 Android Development] elhpianist:
Data=ext4, or All=ext4
[Galaxy S I9000 Android Development] nabilfareez:
bln need to be on or off?? which better??
[Galaxy S I9000 Android Development] elhpianist:
BLN has nothing to do with lagfix, its a feature implemented in this kernel. If you want to know more about BLN, please look at the BLN's thread, the developer is neldar.
[Galaxy S I9000 Android Development] nabilfareez:
i know it has nothing to do with lagfix.. juz wanna ask da bln drain bat a lot or not.. :)
[Galaxy S I9000 Android Development] elhpianist:
Look in the BLN thread, cause your question has nothing to do with this kernel. Also tip, most of the answer you want are from search or uncle google :D
[Galaxy S I9000 Android Development] nabilfareez:
hehehe.. ok.. tq..
[Galaxy S I9000 Android Development] coldhandz:
I've tried many different kernals but I always end up back to Zenkinz. Stable, smooth and fast.

It's great, around 1050 QB, 16.7ish Linpack no lagfix, no tweaks. v1.50

Stock JP8 rom.
[Galaxy S I9000 Android Development] lifelessfreak:
Cool! But how about the OC? Does it works well too? (: I'm interested in this kernal, cuz of the OC function actually :D
[Galaxy S I9000 Android Development] coldhandz:
OC works very well. No FC, no freezing what so ever. Can't fault it.
[Galaxy S I9000 Android Development] do-shaq:
I agree this is the best kernel, no doubt about it!
[Galaxy S I9000 Android Development] tokyogtr:
the beauty of this kernel is it's performance with stability. that and the fact that the dev only updates it occasionally. if it ain't broke, don't fix it. too many kernels and roms out there that jump all over the place almost 2-3 times per day.

i found insanity and ya-ok have a very good release schedule.
[Galaxy S I9000 Android Development] coldhandz:
Couldn't agree more......If it ain't broke..........:D
[Galaxy S I9000 Android Development] wcg707:
When I was on non-JPU, this is the best kernel, fast and stable. Whether its 1.2 or 1.12, it never broke down on me.

Now that I'm on JPU, where lagfix is a non issue, this kernel once tweak and tune to JPU, will be the one to go for. Any development on this JPU release, if any?
[Galaxy S I9000 Android Development] supercurio:
Every developer is waiting badly for new kernel source release, I hope it won't take too long.

Samsung developers are aware of the multiples issues now (I think by inquiry, I contacted one of them directly also).

It's on Samsung side now!
[Galaxy S I9000 Android Development] knocker235:
thanks for your Kernel

but in last kernel v1.50 i have a problem in wifi, i can't connect and it give me always obtaining IP address.

do you have any solution for this problem???

Thanks
[Galaxy S I9000 Android Development] coldhandz:
You may need to reconnect it manually by re inputting your wep key code.
[Galaxy S I9000 Android Development] jsen:
Happened to me. I turned on all tweaks in CWM and wifi works fine.
[Galaxy S I9000 Android Development] oversim:
can I use this kernel with a JPU rom?
[Galaxy S I9000 Android Development] jsen:
answered 2-3 pages back.

NO
[Galaxy S I9000 Android Development] oversim:
Sorry, but be quit please.

As far as I know, K10x kernels work with jpu and non-jpu rom. And they are jpm-sources based...

With JPU rom,we can use

- K10J (JPM-based + XXJPU modules)

- K11-XXJPU (XXJPU stock kbased + some tweak, 2e bootloader, ecc..)

Now, my question was: and what about this kernel?

The answer "because Samsung has not released sources, yet" I think it isn't correct at all (see above other kernel status). Or not?
[Galaxy S I9000 Android Development] dictatorr:
Custom bootanimation supported ?
[Galaxy S I9000 Android Development] supercurio:
hahaha this was big :)
[Galaxy S I9000 Android Development] elhpianist:
Well why dont you try it, if you semi brick your phone dont come here and complain that its not compatible!!!!
[Galaxy S I9000 Android Development] SirM2X:
I really like your kernel, the performance of the phone is awesome and it has so far been the best kernel I've ever used.

There's only a slight problem I have (not sure about others)

My GPS is somewhat useless with this kernel! No sat lock even after about 10mins!

Takes about 4 or 5 mins to even find 3-4 sats! Use to have ~30sec locks indoors with Hardcore's kernel.

Don't really know if it's me or others are having the same issue...

Thank you so much for this kernel! :-)

Keep up the good work.
[Galaxy S I9000 Android Development] zoubidou:
i am using darky's 2.1 with hardcore (K11 alpha) which is not OC. but still have 1950 in quadrant. battery is pretty good also.

GPS is very good, 5 sats indoor in <10 secs., and i am not living in a wooden house in the country, still not the iPhone, but 10 secs is good.

but i will be back to yours a soon as JPU support is there. And i am sure you will do a hell of a job.
[Galaxy S I9000 Android Development] zenkinz:
you can't undervolt, overclock, optimise core of kernel through compiling, etc w/o the source.

if you like the other kernel that are compatible with JPU, then stick with it.
[Galaxy S I9000 Android Development] knocker235:
Regarding WIFI, i tried to turn on all Tweaks but it didn't work with me, do you have any idea??

Thanks
[Galaxy S I9000 Android Development] zenkinz:
tried reboot your phone and see if you have the problem solved.
[Galaxy S I9000 Android Development] tokyogtr:
that's not really just the kernel's fault, it's the combination of rom, modem and kernel. i use insanity rom, ya-ok kernel and zsjpe modem and i get lock perfectly with great accuracy down to 3m.

i tried 7 different modems to get the right one for my rom/kernel combo.
[Galaxy S I9000 Android Development] tokyogtr:
it could also be the lease time has expired and your router is not granting a new lease. have you tried restarting your router?
[Galaxy S I9000 Android Development] techeretic:
i am waiting for this kernel for JPU, best kernel so far IMHO, for ol' JPO, 2200 quadrant score, 1.5 days of battery life under heavy usage and pure lagfree performance...! YA-OK - Yeah Baby!! :P
[Galaxy S I9000 Android Development] knocker235:
:( no hope till now
[Galaxy S I9000 Android Development] zenkinz:
try another router or reboot your router. it could be your router is not leasing out proper id address as some had suggested.
[Galaxy S I9000 Android Development] knocker235:
i tried about 3 or 4 routers, all the same problem

WIFI was working in the old Kernel
[Galaxy S I9000 Android Development] coldhandz:
Hi Knocker235, have you tried menu/settings/wireless and network/wifi settings/turn on wifi

it will show what wifi networks are available and if your connected, if your not connected then /add wifi network/ you should see your router then input your wep key:D

Hopefully that will help you.
[Galaxy S I9000 Android Development] zenkinz:
there's a delay in releasing v1.60 (because I havn't work on it yet! :P) but I should be able to do it by this coming weekend the latest. Key feature is the bootanimation and also try to tweak the kernel parameter to see if the effect on the UI experience.
[Galaxy S I9000 Android Development] zenkinz:
Sorry it's hard to troubleshoot the kernel for such 'wide problem' so there's little I can offer other than the following

1. Flash back your stock Kernel, and see if you can connect WIFI

2. Flash back the entire ROM (yes you will lose your data so make sure you back it up first), do not restore the data, and with stock and YA-OK kernel, see if you can connect WIFI
[Galaxy S I9000 Android Development] shranav:
Please include latest stable speedmod in your kernel. Thanks.

[Galaxy S I9000 Android Development] SirM2X:
Hmmm.... My modem is now JXJPE and in a word it's aweful! :(

My ROM is JPJPG the official release and am using YA-OK now.

Mind telling us which modems you tried before deciding to go with ZSJPE? :confused:

Thanx in advance

Edit: Oh and one more thing. Is there anywhere where I can download the standalone "modem tar" files?

Most of what I've found are contained in a single tar file with the firmware its self.

Wanna try different versions to see which ones work for me.
[Galaxy S I9000 Android Development] tokyogtr:
can i ask what phone you are using? exact hardware? and where did you get JXJPE modem and JPJPG rom?

i've used JPM, JK3, JPP, etc etc. pretty much every modem on the 2nd post of doc's rom.

also, how are you flashing these modems? why don't you just flash cwm versions?

From experience, I have tried JPM, JPD, JPP, BUJP5 and can confirm that the ZSJPE gives me the best GPS results. I am from Australia, and been playing around with GPS settings, but I went back to the original GPS settings and currently getting GPS accurancy to 5-10 metres, with about 6-7 satellite locks in under 20 seconds.

Go to the GPS' thread here and play around with your settings:

[Galaxy S I9000 Android Development] SirM2X:
My phone is GT-I9000 8GB International if that's what you're asking.

There was this guy who worked at Samsung's customer service on some other forum who provided me the JPJPG firmware. For the modem I think when I flashed JPJPG, the modem was updated too not sure though! I don't remember the modem version before the update.

Cool! cmw versions are better! Just didn't know where to find 'em. Thanks a bunch! :cool:

Thanks will do and will report my results.

EDIT: Alright so now I've switched to ZSJPE and it looks really promising. On JXJPE I lost fix occasionally (even moving 10 meters would have resulted in losing fix).

First fix took ~40 seconds with 6 sats. Then suddenly the number of visible sats increased to 10 with strong signals! :-)

Hope it would fix my issues. Will test for like another day and report back!

Thank y'all guys :-)
