Hey for right now I am good. The temp thing can wait i really don't think my temp is going to get to high. maybe we can extract the sensor from someone else that has a working temp. I really don't push my tab to hard anyway.
[Galaxy Tab  Android Development] instechgainza:
any tips for us, what rom are you using?
[Galaxy Tab  Android Development] jkurl:
I am using overcome 1.1.3. Nothing so far. I want to try the sensor file from someone else who has the sensors working that is on the same rom as I am.

Anyone out there that can pull there sensor.default.so file from a working overcome rom 1.1.3 that is currently working w/ this kernel.
[Galaxy Tab  Android Development] VeEuzUKY:
Let me apologize upfont for this question. I just recently bought my Galaxy Tab after almost 5 years using Windows Mobile. So, while I am near-expert at WinMo, I know nothign about Android or the Galaxy yet.

I want to flash my tab with this Kernel but do not have the faintest clue how to do it or where to start. The only think Ive done to my Tab was to root it using z4root. I have not installed the Samsung Kies Application (have no idea if I need it) or done any kodding or flashing yet

Can someone please point me to a guide or step-by-step info on flashing the Galaxy? I think (not sure) Im using a Euro version (purcahsed in Hong Kong P1000ZHJJ1)...

Again, thanks for pointing me in the right direction!!!
[Galaxy Tab  Android Development] bendjlee:
I

Flashed all.known sensors - no go on overcome.

v10 sensors

V11…

v12

Kuodaxi's kernel version.

Ohwell :-S
[Galaxy Tab  Android Development] alexnguyen018:
I suggest you look up Roto's JMI v2 thread. There's a link in the original post of that thread that leads you to another thread that teaches you how to flash Roto's JMI v2 ROM. Once you got that down, I suggest looking up the Modaco kernel thread to convert your Tab's file system to ext4, which will improve speed and performance. From there, flash either the Overcome ROM or Modaco's ROM. Do all this in that order and you should learn all you need to know about flashing the Tab. Good luck.
[Galaxy Tab  Android Development] VeEuzUKY:
OK, thanks a lot, I guess i need to start from scratch. Its funny, since the G1 came out I wanted to drop Windows Mobile and go for Android but my inertia and fear of having to scratch always kept me away.

Today I actually realized (even more) how much WinMo (recently on an HD2) and the Galaxy Tab/Android are literally worlds appart. After messing up with some system files and deleting (useless) some stock applications (like I removed stk.apk and other stuff) I ran into enough problems to decide and do a full hardware reset, only to be slapt on the face with the reality that things only got dramatically worse. All the missing system apps are still missing (I thought they'd be "restored") and basically nothing works anymore. So I learned that on the Tab a hardware "system reset" doesnt really reset anything except user installed apps and settings. What you've deleted from ROM or got messed up will not come back to life. So first of all I just need to find out how to to real full restore where all system files, all missing files and positively everything gets back in the Tab as it was originally shipped, after that, Ill venture into more stuff... or maybe I should just flash the whole thing into a new ROM (maybe on the newwer Gingerbread builds)...

Its funny, I go from years of WinMo knowing all my ways around, even how to cook ROMs for the HTC HD2, to positively having no clue what I doing with the Galaxy Tab... depressing and ego-crushing...:(:(:(
[Galaxy Tab  Android Development] Stu308:
Was going to flash this kernel, but reading through all the issues I dont think it's worth doing just yet. Hopefully it will all get sorted eventually. :)
[Galaxy Tab  Android Development] shmigao:
It was quite an ordeal to get back a working tab after v11 screwed it over.

v12 boots fine and feels faster in times, but then I have regular extreme lags to total unresponsiveness (need long press power to shut down restart) - e.g. just now as I tried to type this while listening music.

Video skips.

It almost feels there is a memory leak or some extreme cache built up. I am not a dev so I don't know...

Waiting for v13... May flash back to Modaco r3 Kernel... But Voodoo sound is really cool
[Galaxy Tab  Android Development] lambstone:
To fix the accelerometer in the games, flash the v12 kernel first, then afterwards download then v11, extract the sensors.default.so from v11 and push it into your tab.

(if it says read only when using adb, remember to do a adb remount)
[Galaxy Tab  Android Development] kay_kiat88:
just flashed v12. sensors didnt work for v12. copied v11's sensors and everything worked except temperature. any idea guys? or anyone has all the sensors working?
[Galaxy Tab  Android Development] natious:
all sensors working here, v11

except i dont have a preview when using the front camera in fring
[Galaxy Tab  Android Development] kay_kiat88:
apparently this guy called noobleskill PM-ed me last night. this was what he said:

"http://xda.richardtrip.org/tab/Galax...CR_ext_V11.zip

get that one, there are 2!! the first one doesn't work.... Do a nandroid into the last good rom you had, as soo as it gets to recovery, flash Moco r1, then straight after the flash of that, again flash the V11 from the link above.... now wait for it.... and **** yourself cause it took all gosh darn weekend to get here but now you are!!!!!!!!

"

didn't try as v12 was out and v12 worked for me except temperature sensors.
[Galaxy Tab  Android Development] shmigao:
yes, thanks that did the trick. Thanks!
[Galaxy Tab  Android Development] kay_kiat88:
yeah no problem. so far from all the post i've read. only 2 or maybe 3 people has got the everything working including the temperature sensor. is your temperature sensor working?
[Galaxy Tab  Android Development] Qsilver2001:
I'm on modaco r3 kernel, roto jmi v2.. my temperature is also not working :(

Stay at 30C forever. Still considering to flash either Richardtrip's V12 or koxudaxi kernel.
[Galaxy Tab  Android Development] kay_kiat88:
on r3 we don't have to worry much about the temperature as it is not overclocked. on v12 temperature sensors are not working. but i still flashed it anyway. i don't really overwork my tab so i think it's not really a concern for me. speed is a concern for me though. depends on how you see it. just giving you my views about it:)
[Galaxy Tab  Android Development] realerdom:
Can not download the ROM, any mirrors?
[Galaxy Tab  Android Development] kay_kiat88:
it's not a rom.. it's a kernel.. know what you're flashing! don't flash the wrong stuff!
[Galaxy Tab  Android Development] kay_kiat88:
when i chose interactive, according to setcpu widget the processor is stuck at 1400mhz. dunno whether it's actually running at 1400mhz or just display bug. using modaco rom.
[Galaxy Tab  Android Development] richardtrip:
I think i know how to fix the sensor problems. Just have a little patience. New version later this evening.
[Galaxy Tab  Android Development] antiochasylum:
Sweet!!!!!!!

Edit: flashed v12 and extracted v11 sensors and everything works except temp. Awesome. I can live without temp since I only OC to impress :P
[Galaxy Tab  Android Development] Basil 123:
OMG- that will make it totally ------Perfect.

The voodoo sound - tweaked using an app from market makes the sound amazing btw.

Thanks

Basil

PS dont call it V13 - dont want it to get jinxed :-)
[Galaxy Tab  Android Development] jkurl:
Richard,

Thanks for working in this. Can't wait to get the new version.
[Galaxy Tab  Android Development] TheGrammarFreak:
Even if you break the other sensors, make the temperature sensor work. :)

Update

Version 13:

*update sensor drivers (all sensors seems to work on MCR R1)

*Update sensors.default.so

Tested gyro with NFS and working fine (not that i race any better now, but thats not the sensors fault :-)
[Galaxy Tab  Android Development] richardtrip:
tested the temp sensor of V13 with setcpu and "Temp+CPU V2" widget and it goes up when stress testing (and goes down when i stop the test).
[Galaxy Tab  Android Development] MaxiJavi:
Awesome Kernel ...

Works great for me on Modaco R1

150, 100, 75, 75, 75, 25, 50

However, conservative seems smoother than on-demand (is this possible?)

And if I SetCPU with on-demand, and a screen-off profile of 800 with conservative I get random lockups when screen is off.

However, I took those out and it runs like a dream :-)
[Galaxy Tab  Android Development] Basil 123:
Wonderful. Now 100%, goes without saying, being able to watch temps is reassuring while using an OC kernel.

Thank you Richard :-)
[Galaxy Tab  Android Development] bendjlee:
+1
[Galaxy Tab  Android Development] jkurl:
Mine is back up as well. You rock good sir. Well done.
[Galaxy Tab  Android Development] pkoper:
Could someone check how .mkv playback is with v13?

Not sure if it is the kernels fault.

Tried v12 and the modaco kernel with several roms (EXT4) and .mkv playback just stutters. Stock roms are fine though.

Or am I missing something?
[Galaxy Tab  Android Development] MaxiJavi:
I believe it is due to the Ondemand governor.

I got a little stutter with this.

Change it to conservative and I think it may fix your problem.
[Galaxy Tab  Android Development] :
with this kernel is possible to use SetCPU to set the max clock speed (in the range 1ghz - 1.4ghz) or the speed is set to 1.4ghz ?

thx
[Galaxy Tab  Android Development] wallah:
Everything fine here, Overcom 1.1.3 kernel v13, flash via recovery, zero problem !!!! :-D

Thanks a lot richardtrip, you are the best !!!

with SetCPU?
[Galaxy Tab  Android Development] Peter Unger:
Now my temperature sensor works too - just perfect :)

Very good to see, the 7" Tab rocks so well after this mod - just realized, that there will be no successor for it and there is only the chance to "pimp" the old one :(
[Galaxy Tab  Android Development] maxtcee:
i know this says euro but can i flash this on att or do i have to change the modem after as well?
[Galaxy Tab  Android Development] TheGrammarFreak:
Back up your current kernel, then try and report back ;) if it fails, flash your old kernel with heimdall

[Galaxy Tab  Android Development] daniel.weck:
Hi, I've compiled my own kernel with the Voodoo Sound patches, everything seems to work except that the Market app (Voodoo Control) doesn't detect the driver (it thinks that the kernel is not Voodoo-enabled). Does it work fine with this kernel ? @richardtrip: any tip on extra steps needed to make the app recognize the driver ? Many thanks :) Dan
[Galaxy Tab  Android Development] richardtrip:
Voodoo control app is working fine on this kernel. Can't tell what you did wrong because i don't know what you have done (check my github to get a clue).
[Galaxy Tab  Android Development] natious:
v13 perfect on modaco R1.

What is this voodoo sound tho, i installed the app but i dont know what options to pick.

thanks for the great work
[Galaxy Tab  Android Development] Justin^Tan:
hmm, i just gogling and the voodoo sound works to make the sound is more significant for galaxy s

i tried and its kinda works for galaxy tab also

but the bass is still nowhere near what i want

i have korean PMP with woflson chip too and the sound is on par with ipod

and 1 thing that doesnt work on tab is galaxy tuner, which to manage the sound equalizer of the hardware?

can anyone give me a link to a post or explain this to me in a more clearer way, what i really need to get a bass boost as i see that who knows this can replace my PMP

thanks before
[Galaxy Tab  Android Development] knightnz:
Download PowerAmp. It has manual equalizer, treble & bass settings.
[Galaxy Tab  Android Development] knightnz:
A score of over 2300 in Quadrant with this kernel and the Overcome firmware. Amazing.

I've undervolted mine to 1350mV @ 1.4Ghz and it seems to be perfectly stable, using the "Performance" governor which locks it at full speed all the time (and chews through the battery! :)
[Galaxy Tab  Android Development] shmigao:
Quick Q, which one is the Performance governor? Not clear about the abbreviations in xan's app

Could you share your voltage levels?

Thanks

Edit, I guess need to use SetCPU for governor, correct?

Which scheduler in xan's app to choose?
[Galaxy Tab  Android Development] knightnz:
It's the one called "Performance" in SetCPU.

So far, I've got;

1400 = 1350mV

1300 = 1275mV

1000 = 1200mV

800 = 1175mV

400 = 1050mV

200 & 100 = 950mV

I haven't done much experimenting. To work out good stability you'd need to lock the maxCPU to each given value, set the governer to "Performance" to lock the speed that that value, and then keep reducing the mV until you get issues, then move it back up by 25 or 50mV. (Best for 50mV, obvious issues may appear at -50mV, non-obvious ones may still exist at -25mV)

If I have time I'll have a play later. The CPU in my Nexus1 will run perfectly stable at 925mV @ 1Ghz so it'll be interesting to see how low the Tab will go!

YMMV - Different CPU's have different tolerances, what works for one may not work on another, or may even damage it.

Overclocking doesn't damage CPUs, over-volting can though.
[Galaxy Tab  Android Development] Stu308:
Hi, i flashed last kernel with odin. It states on here you can flash this with recovery. How exactly do I do it this way? It sounds a lot easier. I copied zip onto sd card root, then went to install zip in recovery, but it doesnt show.

I have cwm and ext4 on my tab.

Thanks.
[Galaxy Tab  Android Development] jrjunior:
75C

Hi,

I am quite new to the tab and flashed that kernel using CWM. The battery shows now 75C and the tab stops charging. Of course, this temp is not correct.

Any idea what went wrong?
[Galaxy Tab  Android Development] shmigao:
Cool, I am trying it out as we speak

Still have occasional total unresponsiveness from time to time... Don't know where that came from...
[Galaxy Tab  Android Development] knightnz:
After a bit of experimenting, looks like I can drop most of the voltages right down and it's still fine, should run much cooler. 1.4 Ghz @ stock voltage (1.25V) - maybe we should shoot for 1.6Ghz? ;)

So this is what I've got which seems nice & stable;

1400 = 1.25V

1200 = 1.1V

1000 = 1.05V

800 = 1V

400 = .975V

200 = .95V

100 = .95V

I'll give it a run and see how it goes, no problems so far though, Quadrant scores are consistantly >2200. Very impressed, it's like a different device than when it was on stock kernel.
[Galaxy Tab  Android Development] natious:
The gyro is working for the home screen, but not for games :(
[Galaxy Tab  Android Development] shmigao:
works here though... maybe try reflash v13, or push sensors separately?

you may also try fix_permissions after flash v13. someone further up suggested that, and I do that always anyway.

fix_permission within CWM recovery still doesn't work though, need to invoke separately
[Galaxy Tab  Android Development] shmigao:
trying it out with the same values.

are you using xan's app? there are "scheduler" settings i do not understand.
[Galaxy Tab  Android Development] shmigao:
You have to put the zip on external sd card. CWM recovery cant flash from internal sd for some reason

Remark: backup before flashing anything
[Galaxy Tab  Android Development] natious:
my senors only work when i push the sensors.so from v11, v12/13 only works in homescreen and breaks temp and preview of my front camera in fring, v11 everything works

so im using the v13 kernel with the v11 sensors.so

edit: I dont think my temp is working, its been on 34* after i left my tab infront of the aircon for 5mins, the tab was ice cold. :/
[Galaxy Tab  Android Development] shmigao:
did you try extracting the sensor files from v13 and push them separately?

strange. i tested it with NFS and it worked
[Galaxy Tab  Android Development] antiochasylum:
Everything works on mine. Awesome work Richard. Many Thanks.
[Galaxy Tab  Android Development] crisvillani:
Everything working good for me thank you Richard!
[Galaxy Tab  Android Development] knightnz:
Xan's app gets the job done nicely. To go any further I might shift the values manually via shell. I don't expect to be able to drop the 1.4Ghz value much more, but there's probably a bit of room in the lower speeds.

Don't worry about the scheduler options, there's very little difference between them from a usage standpoint and apparently some of them aren't implemented very well. They won't make any difference for the speed of a given application but they can improve the speed of state-changes (multitasking). They've all got up & down sides. Try bfq & noop and use the device for a while, see which feels snappier for your usage.
[Galaxy Tab  Android Development] kay_kiat88:
+1. it'll lag occassionally. shmigao, i realized we have very similar tabs we very similiar problems. lol.
[Galaxy Tab  Android Development] maxtcee:
do you have to push the file or can you copy and paste it from root explorer
[Galaxy Tab  Android Development] knightnz:
Nuff said.

Copy paste works too

Came from MoDaCo r3 kernel, just update through cwm to v13, work rights the 1st try ;) sensors are all running, with Overcome 1.1.3 rom
[Galaxy Tab  Android Development] alexnguyen018:
This kernel just breathed new life into my Tab. Seriously it runs so nice now. After I rooted my Tab and flashed the Overcome ROM, I had some lag in games like Fruit Ninja and The Impossible Game. Flashing this kernel fixed the gaming lag problems. Awesome! Good work! Thanks pressed...many times haha.
[Galaxy Tab  Android Development] jrjunior:
Anyone knows why my temp sensors are so off?

Sorry to bump my own thread, but does anyone of you know why my temp sensor is so far off? OK, it's hot in Singapore but not that hot
[Galaxy Tab  Android Development] fastcx:
Try to clear cache,dalvik-cache,& battery stat and see how things go
[Galaxy Tab  Android Development] lambstone:
Just a question does anyone have the UV settings? For instance what are the default voltages for the range of clockspeeds and also whats the maximum that we should UV?
[Galaxy Tab  Android Development] KChauJen:
:) It's hot in Vietnam too, but it's not so bad when the GT-P1000 on battery charging, is 42C, and on using without battery charged, is 36C.

Actually, my GT-P1000:

JMG (De-block-Bootloader) -> OverCome v1.3 -> r3 EXT4 Modaco (kernel) -> MCR Ext4 v13 (1.4ghz).

and it's running stable right now. I'm still using & checking with accompanied Voltage app with this kernel.

Please check the Voltage app. and find out what is your modified configuration. It is possible caused your high temperature.

FYI

Edit

On fast battery charge, the temperature is high, but after 85% of full, the charge is going slowly and the temperature goes down to 36.5C
[Galaxy Tab  Android Development] shmigao:
user knightnz posted some good values further up
[Galaxy Tab  Android Development] kay_kiat88:
anyone got random freezes?
[Galaxy Tab  Android Development] TheGrammarFreak:
I had a few, but that was due to dodgy profiles in setCPU
[Galaxy Tab  Android Development] danielherrero:
Hi

Do I ve to use the useCPU App.? I ve run it and says max speed at 1GHZ. I ve modified it to 1.4 max and 0.1 min and governor ondemand on setCPU. I ve passed from 1700 points in Quadrant to 2200. But , is this the way to use this kernel?
[Galaxy Tab  Android Development] celestar32:
I have installed V13 and overclocked it to 1200mhz. I'm on Overcome 1.1.3 rom and have not encountered any freezes or lags. I only noticed when bootup there is a bit of video distorted lines. When playing PES2011 it was as smooth as silk. All sensors are working perfectly. My temperature range read at 36.5 to 36.9.

Nice work richardtrip!!!
[Galaxy Tab  Android Development] vandunga3:
Hi there. After flash this kernel using EXT4 recovery mode, my galaxy tab goes from 24% of battery to 3% and after using awhile, my tab turns off and i couldnt charge it because it shows this error " Charging pause because of the temperature of battery is too high or too low " Could u guys please help me to fix this ?
[Galaxy Tab  Android Development] KChauJen:
It's really hard, to say, fixing your problem because we don't know your firmware and the apps running in your system, but, firstly, just turn your tab off and charge your battery and when the battery is full, then look at the Voltage configuration, and lastly, find out the firmware...

Good luck.
[Galaxy Tab  Android Development] schmolch:
My mental strength against overclocking my tab is weakening every day.
[Galaxy Tab  Android Development] vandunga3:
Hi there. My tab hasnt been installed any software yet. Im running overcome 1.1.3. I turned off my tab but when i charge it shows a thermometer flashing on the right hand side of the battery

Let it cool down, before plug it in for charge.

Take time, bro. Nothing to be hurry.

Is overcome faster than modacos Tom?

Sent from my Galaxy Tab of awsomeness
[Galaxy Tab  Android Development] MaxiJavi:
Ummm ...

I enabled geo-location in the browser and the GPSD went into a loop.

The tab was in my coat pocket so I only noticed when it got a little hot :-)

I have now set a SetCPU temp profile, any idea what a good temp to scale back at would be ?
[Galaxy Tab  Android Development] dave18:
No,think modaco's rom is faster. Just that i had connection problems so i switched to overcome (which is problem free).
[Galaxy Tab  Android Development] shmigao:
I still do

I tend to believe it's because the struggles we had at the beginning and the funny way we recovered the backup.

Some settings might be out of whack.

I had to re setup gmail and email to get them back working.

I guess a complete wipe and fresh install will resolve the random freezes
[Galaxy Tab  Android Development] kay_kiat88:
hmm i don't really have major freezing issues actually only happened once. it's just random stuttering when scrolling through the app drawer. either way i'm backing up apps and data with titanium now. gonna install the wipe version for modaco and then restore with titanium backup. i'll see how it goes.
[Galaxy Tab  Android Development] MaxiJavi:
Have you tried changing the governor to "conservative" ?
[Galaxy Tab  Android Development] jrjunior:
I installed now the same configuration as you have - still no success. The tab is not hot at all but SetCPU still shows temperatures around 70C. Charging is impossible because tab refuses to charge because of too high temp.

Should I try the older sensors.so as described somewhere else in this thread?

Would love to have a working kernel with Voodoo but I guess that I have to live without until the next version.
[Galaxy Tab  Android Development] KChauJen:
Instead of using SetCPU to find out how hot of your Tab, use the Widget Elixir.

The temperature degrees given on the previous post were from this Widget.
