I'm pretty sure I just bricked my **@#*& phone trying to Flash this Kernel :(

It failed the first time around when I tried to flash it via Odin.

So I took the battery out like I usually do then went to put it back into download mode... To my surprise I cannot get into download or recovery mode anymore.

I've tried all button methods and none worked. I can't get past the screen that has the cell --- computer screen.. Looks like I may need a jig now...

Any other ideas that I might be able to try?

Thanks.

Never had problem with flashing this kernel via Odin or sgs kernel flasher.Maybe bad odin version or something wrong with usb port or something else.Leave the battery of the phone longer 15 to 30 min then try to enter download mode

Stock JVR with Semaphore 1.6.0bm
[Galaxy S I9000 Android Development] gorylutza:
The best kernel

Hy,

I wanted to thank you for this great kernel.

I have installed Semaphore 1.6.0bm for 4 days now and all is great.

Good battery life, even with the oc script activated.

Keep up the good job.
[Galaxy S I9000 Android Development] HM.Carbide:
Did you check bootloader, or flash it as bootloader?
[Galaxy S I9000 Android Development] M.Sami:
try to flash the pit file only via odin (with repartition) and then after restarting the phone flash the other 3 files without the pit file (phone-csc-modem), and I dont think that Darkyrom 10.3 can be used on a fascinate!!
[Galaxy S I9000 Android Development] iwebsource:
It works fine on the fascinate. I've been running the DarkyROM 10.3 on the fascinate now for over a week without any issues.

I can't get the phone in download mode anymore

The issue is when I tried to Flash the Semaphore via Odin3.

I selected the Kernel in the "PDA" slot, not the Bootloader slot.

Try holding the Download Mode button combo for 30 seconds.
[Galaxy S I9000 Android Development] gsw5700:
Wow, so far, it looks great, everything appears to work, normal video is fine, now got loads of free memory, this kernel just keeps getting better,

Anyone got any suggestions how I can best utilise all this memory?

Thx stratosk

I've had this problem, what worked for me was to take battery out, hold down 3 button combo, whilst still holding them insert battery, can be a little tricky, once battery was in it came up with download mode. You may have to try a couple of times. Hope it works for you.
[Galaxy S I9000 Android Development] roundbelly:
hey the other day i flashed the 1.60 bm on a stock jvr and got a bug (i think) when i lock my screen i'm getting a green screen flash before the screen is off. can anyone explain this and tell me about the potential solution(s) thanks
[Galaxy S I9000 Android Development] pikachu01:
Try increasing the gamma a little bit by dragging the 3 sliders together.
[Galaxy S I9000 Android Development] iwebsource:
I tried this. All it does is constantly reboot the phone over and over, getting the Phone --!-- PC screen. :confused:
[Galaxy S I9000 Android Development] iwebsource:
Thanks for the tip sarbe, I'll give that a try when I get home later on
[Galaxy S I9000 Android Development] awesomeandroid:

Semaphore 1.6.0bm is awesome!!! THANKS!

Your welcome m8, I hope it works for you.
[Galaxy S I9000 Android Development] nalu_pl:
Hi there!

I'd like to thank Semaphore for this kernel (1.6.0)

I have VERY good battery life (see pict.) and performance. Today it's 4'th charging cycle.

Maybe it's not a big deal for others, but for me it's very important thing.

Cheers! :D
[Galaxy S I9000 Android Development] stoske:
This can only be achieved if you don't use your phone as smartphone.

Battery cannot last more than one day with average usage - syncs active, FB, Twitter and emails.

Here is my score, no 3G, no Wifi,.just calls (48 minutes in 5 days), no games, no nothing (phone was in the room, me on the beach) :)
[Galaxy S I9000 Android Development] darckengel:
With average use, you reach easily 2 days.

If you use you phone just for basic usages (sms/call), you can keep it for almost 5-6 days.
[Galaxy S I9000 Android Development] stoske:
My daily usage is 1 hour of calls, up to 2h display time, 10-15 emails and couple of SMS's and I cannot make 24 hours (battery properly calibrated)

This is from today (I charged the phone last night)
[Galaxy S I9000 Android Development] roundbelly:
how to do that?? i don't have the slightest clue
[Galaxy S I9000 Android Development] pikachu01:
In Voodoo Control, Gamma, Drag the 3 sliders to the right a bit
[Galaxy S I9000 Android Development] HM.Carbide:
Simplest is to press 2.3.3 defaults (values 0, 0, 0).

Every negative gamma causes the green flash.
[Galaxy S I9000 Android Development] darckengel:
I use -50/-53/-44 and i have no green flash.
[Galaxy S I9000 Android Development] gsw5700:
This is weird, on bigmem oc I can run at 1275 mV, I need at least 25-50 mV on other kernels, why do some kernels need less voltage at the same cpu frequency?

Sent using geek power
[Galaxy S I9000 Android Development] stratosk:
Do you mean that you need more or less voltage on other kernels? I think one reason maybe the time the cpu remains in the specific frequency.
[Galaxy S I9000 Android Development] gsw5700:
I'm happy that semaphore needs less voltage, just wondered why one kernel would need less voltage than smoother

Sent using geek power
[Galaxy S I9000 Android Development] stratosk:
I really don't know the exact reason. We have to compare sources to figure this out.

Which kernel do you mean? Galaxian, Talon?
[Galaxy S I9000 Android Development] gsw5700:
semaphore (for me) requires less voltage than galaxian. I find this strange, surely a CPU running at frequency x would need the same voltage regardless of the kernel !

[Galaxy S I9000 Android Development] Al3cks:
That is normal power consumption. I notice you use HSDPA (uses a lot of power for packet send/receive) for data connection and your K-9 mail client is waking up the phone quite a lot. Reduce mail check frequency or forward your mail to a Gmail account you will set up on your phone and give up using K-9, or set up Gmail to fetch your mails from your current account, switch to GPRS when you are not browsing the internet, switch off your connection at night or disable mail checking during the night, consider using Juicedefender to switch on your connection at specific intervals and to keep it disabled during the night. With your usage pattern and the above recommendations you should get more than 1 day, even more.
[Galaxy S I9000 Android Development] stoske:
@Al3cks

Thanks on your excellent advices, I am already aware of these options, but I am not interested tweaking everything to make couple more hours of battery life.

K9 is only on push, and I needed for my business. I have couple accounts...

I am just saying that it is not possible to make 4 days mark with this or any Android phone if you use it as smarphone.

From my stand, it is deception of future users of this kernel or any kernel.
[Galaxy S I9000 Android Development] dani_z:
Stratosk, JVS is already on Samifirmware.com :)
[Galaxy S I9000 Android Development] Al3cks:
Yes, if you use your smartphone for what it is then you can't expect more than one day out of your standard battery. I never tried to use it strictly as a phone (no data, no wifi, no bt) but I'm guessing if I did so, I would get more than a couple of days of battery use.

This kernel is the best among the many I have tried. It's the only one keeping my phone stable even at 1.2 GHz, no UV. Combined with stock JVR ODEXED it is so smooth. I hevily themed this ROM but it's still smooth compared to other deodexed ones.
[Galaxy S I9000 Android Development] Valinorian:
I put JVS on my phone then flashed 1.6.0 kernel. Getting Wifi bug, keeps turning Wifi off. Just letting you know :P Going back to JVR :P

Edit: Thought I give it a 2nd try. reflashed stock JVS, wifi working, flashed 1.6.0 and again Wifi not working. :(
[Galaxy S I9000 Android Development] MasterJam882:
Pls tell me that ur working on a JVS kernel stratosk^^

Need overclocking on this rly bad^^

Else samsung has to release JVS offical very soon.

This ROM is rly rly gd and with semaphore kernel it would be much better.

I can't believe that everytime they release a new ROM it's getting better and better. This shows clearly what potential this device has and that an end of support is not near at all!

[Galaxy S I9000 Android Development] gsw5700:
You don't OC individual apps, the entire kernel or phone is OC'ed People generally do this to get a better gaming experience or to simply get a more responsive phone (at the expense of battery life to a degree)

Does 1.7.0 add anything, and does anyone know if it is smoother than DarkCore 4.0?

Does this have RAM management improvements? Mine dropped pretty quickly to 90 MB...

Still smooth, but not enough for big games and stuff.
[Galaxy S I9000 Android Development] stratosk:
I will release bigmem version tomorrow and as soon as everything is OK with the standard version.

Wifi works ok so far. I will continue testing and report back.

The new version it's the same with 1.6.0 (comparing features). It just includes JVS initramfs.
[Galaxy S I9000 Android Development] zenosteam:
i can't find this oc scrip in the op !
[Galaxy S I9000 Android Development] DarkSorcerer:
My friend,

That script in on your phone, in /res/scripts (to access it - or any other -, try Supermanager or rootexplorer).

Then, copy it to /system/etc/init.d and give it executable permissions. Like read, write, dance, roll-over, whatever.
[Galaxy S I9000 Android Development] bassie1995:
Sounds nice, VERY NICE!

Will look for it tomorrow. Disable lagfix is almost touched already :P

WiFi issues can be solved already, some people on the Darky forum said that the problem lies with the router's DHCP settings.

''Ok, I also had the DHCP address reservation for the IP of the galaxy S.

I removed the reservation and the WIFI WORKS FINE NOW. It seems that there is

some problem in the DHCP request from the galaxy.

does someone know if the ROM+Kernel flashing affect also the MAC ADDRESS of the WIFI adaptor?''
[Galaxy S I9000 Android Development] stratosk:
I confirm Wifi instant disconnections with 1.7.0 on JVS.

Wifi disconnects and the connects again. This happens every few minutes.

I'm sorry for this inconvenience but it seems we have incompatibilities due to outdated sources.

I don't consider this as a critical issue and I will keep the version in public release for further investigation on this.
[Galaxy S I9000 Android Development] bassie1995:
That's weird. It isn't related to your router? I have no problems up to now.
[Galaxy S I9000 Android Development] stratosk:
No, it's definitely not related to router. I have never had issued with this router on JVR.

I'm testing different wireless encryption methods to check this.

Wifi disconnect instantly and reconnects again immediately. This happens every few minutes. So , you have to watch this in order to see it.
[Galaxy S I9000 Android Development] bassie1995:
What's the best way to watch it?
[Galaxy S I9000 Android Development] stratosk:
If you are with screen on for few minutes you'll see wifi icon to disappear and then appear again aftet 1-2 seconds.
[Galaxy S I9000 Android Development] bassie1995:
I'll test it now, on DC 4.
[Galaxy S I9000 Android Development] fredbull:
A little question, what's with "Auto brightness" with JVS+Semaphore1.7.0 ?
[Galaxy S I9000 Android Development] bassie1995:
It's been acting weird for a couple of firmwares now... I don't use it, problem solved :P
[Galaxy S I9000 Android Development] bassie1995:
Stratosk: Haven't seen the WiFi icon disappear (yet?).
[Galaxy S I9000 Android Development] scorpeeon:
that's strange i'm using this kernel and experience no disconnects.. i stared at the wifi symbol for like 4 minutes and it remained stable. so if this problem exists it must depend on the network..

so what do you recommend, go back and use the stock JVS kernel until samsung releases the new sources?
[Galaxy S I9000 Android Development] stratosk:
Maybe it's related to wireless network parameters or with DHCP. do you use static IP?
[Galaxy S I9000 Android Development] stratosk:
Auto brightness seems ok :)
[Galaxy S I9000 Android Development] stratosk:
I don't recommend anything. No offense at all, but this is a leaked ROM with a custom kernel (with outdated sources). I don't find this critical and I can live with this. In the worst case you have to refresh a page when the disconnect occurs when the page loading.

I don't go back :) After all maybe there is a solution on this. I will keep investigating this.

Waiting for sources is not a solution. Last time we were waiting for a long time for new sources.
[Galaxy S I9000 Android Development] bassie1995:
Yep, I have given my phone a static IP at my home router, for adbWireless.
[Galaxy S I9000 Android Development] fredbull:
Cool, thanks :)
[Galaxy S I9000 Android Development] scorpeeon:
yeah, i think i won't go back either until it gets really annoying. and so far i haven't experienced this problem at all :)

one strange thing that others said this disconnection happens also with stock kernel. that could mean even new sources wouldn't fix this.

it's pretty ironic, 2.3.5 was supposed to improve network stuff.

but as i don't have any problems now, and even if i had stock kernel probably wouldn't fix it, i stick with semaphore. stock kernel wouldn't be a solution anyway cause i can't live without voodoo sound :)

i hope this problem will be investigated soon.

What's new and/or what fixes/enhancements are in JVS from JVR? Just wondering when it would be necessary to go JVS.
[Galaxy S I9000 Android Development] pikachu01:
Just the initramfs changes. Lots of people in JVS are experiencing wifi issues. Best to wait for it to be stable before jumping in I suppose.

JVS brings Android 2.3.5:

http://www.androidauthority.com/android-2-3-5-gingerbread-release-date-july-11-monday-18720/

Fixes for signal reception issues

Widget for 4G settings

Teletype (TTY) support

NI push support

NFC secure element

As most of these features doesn't concern the SGS, it shouldn't change many things at all, maybe somme bug fixes, and a new modem.

Hmm i got a werid Bug.

I dont know if it is Kernel-related or not.

I use Simplicity Rom + 1.6 Semaphore

I OC to 1.2Ghz and when i listen to music... my phone crashed and shut itself down...it doesnt reboot (so no soft-reboot) it totally shut down...

This only happen when i listen to music and the screen if off.

Right now im trying to use no OC and observe what happen....but is this bug kernel-related ?
[Galaxy S I9000 Android Development] HM.Carbide:
Are you undervolting? Because listening to music in sleep mode uses 400 mhz. In normal use this frequency isn't used so much. Try not to or less undervolt.
[Galaxy S I9000 Android Development] B-Ace:
Nope Im not undervolting at all...it just OC to 1.2Ghz only without using any CPU app.

This really is weird... it only happen to me while listening to music... sometimes it crashed after 30min and sometimes after 10min..

I can play games or do other stuff without having this issue...
[Galaxy S I9000 Android Development] haloimplant:
You guys getting a green flash every time you turn off the screen with JVS/1.7.0? Not a big deal just curious what's up with that. I didn't have stock kernel long enough to notice if it was there.
[Galaxy S I9000 Android Development] stratosk:
This is voodoo control side effect. It exists in all kernels that support voodoo control.

Try increase gamma settings or reset to defaults in voodoo control application.
[Galaxy S I9000 Android Development] yagami:
Does this mean that Samsung already published the JVS kernel sources, or is this the old kernel sources just recompiled for JVS ?
[Galaxy S I9000 Android Development] MasterJam882:
FYI

for all here who have the wifi problem. It's a problem with firmware and DHCP settings.

If u deactivate DHCP in your router settings it should be all fine again.

Guess those ppl here who don't experience wifi problems like me also don't use DHCP - maybe I'm wrong but u guys can tell me if I'm right by looking in ur settings.

[Galaxy S I9000 Android Development] stratosk:
After testing this on stock kernel I confirm that this is not kernel related.

This also happens on stock kernel.

Thanks MasterJam882. I will try this.

I will try tonight to release a bigmem version.
[Galaxy S I9000 Android Development] Skkip:
@stratosk:

Would it be possible to drop the 100MHz frequency and add a 600MHz frequency instead? 100MHz and 200MHz seem to use the same internal and external voltages according to tegrak oc. So we could perhaps drop 100MHz in favor of better scaling with a 600MHz step and increased responsiveness due to idling at 200MHz.

Thx in advance

Skip
[Galaxy S I9000 Android Development] MasterJam882:
Yeah m8. As is said it is definitely firmware related and NOT kernel related. Just to state that for everyone here!
[Galaxy S I9000 Android Development] haloimplant:
Weird I use DHCP (with static settings for some of the computers but not the phone) and haven't noticed a drop yet.

I remember a while there was a wifi driver one could flash separately to fix some issue (i think it was battery life) with some froyo roms. Maybe this firmware has a wonky driver and someone could put a known good one, like from JVR, in a zip file?
[Galaxy S I9000 Android Development] haloimplant:
I'm not sure if you are aware but clocking slower saves power even if voltage isn't reduced. Digital circuitry power consumption goes with f*V^2 so while lowering voltage helps alot, power consumption still goes down linearly with frequency at a fixed voltage. Removing the 100 mhz mode might be pretty bad for idle battery life with the cpu burning about 2x the power.
[Galaxy S I9000 Android Development] rom08:
Default internal for 100 MHz is 1000 mv and for 200 MHz it is 1100 mv. External voltage for both frequencies are 950 mv.
[Galaxy S I9000 Android Development] Skkip:
but you have to keep in mind, that if we are in suspend mode we use deep sleep. only if the phone is active this will kick in :) So basically it will decrease battery life i agree, but it may increase it too because of better scaling (perhaps with conservative governor).
[Galaxy S I9000 Android Development] stratosk:
haloimplant explained a good reason for not doing this.

Don't worry about responsiveness because with ondemand governor the cpu will clock to maximum frequency immediately when there is the necessary load.
[Galaxy S I9000 Android Development] Skkip:
with previous versions of tegrak it showed 1100 mv and 1000 mv but the most recent version shows the same external voltage.
[Galaxy S I9000 Android Development] Skkip:
yes, that's right. also with the default sampilng rate it scales up to quickly. try 80000 or 100000 and you will see that taking a longer timespan to measure if upsacling is needed really improves battery life at the cost of a few ms responsiveness (which could be ignored since its about 30ms).
[Galaxy S I9000 Android Development] darckengel:
If you use conservative, you want more battery saving than responsiveness, so there's no point to suppress the 100Mhz as the goal is to be the nearest of it.

If you use on demand, the CPU will first go to max freq and then goes down, so there's no point too on supress the cpu freq.

As it was said before, with same voltage, the CPU works 2x more at 200 Mhz than at 100Mhz, so you can easily understand that it will use 2x more power at 200Mhz for the lower frequency, so i don't see the interest of removing the 100Mhz.
