i think its due to that stock kernel is on JFS while speedmod kernel is on EXT4 ... i am not totally sure as thats my theory, maybe u can ask hardcore at the same time wait for someone here with much more technical experience to explain ...

i mean the kernel file system itself .. not ur phone system .. i think .. haha

ops .. i meant RFS .. my bad my bad ...
i think i tried once b4, using no-RFS advanced or is it to ext4? not a fan of lagfix though, the longest lagfix i use was OCLF since the early age of SGS with eclair .. oh that bring back memories

500hz FTW! ...

Generally, u can just flash it on top without disabling the voodoo lagfix .. but the best practice is to remove it then only flash a kernel ...
rmb to enable the tweaks once u got speedmod ..

wat did u do? more specific details please ... or u just only flashed the pit file? it requires a combination of files to flash and different firmware requires different pit file, for example, official asia firmwares all requires 513pit and other than that wont boot ...

no significant difference between iphone 3gs and my sgs, shutter speed depends on settings .. but i am not sure since i seldom use the camera much ...

17hrs with those kind of usage .. consider ok wert, furthermore u r in a custom rom sure will drain more battery compared to official roms ...
about the wifi, i think u better update ur wifi to dxjpa modem, uses less battery compared to stock xxjpy ...

8hrs only? .. impossible ... i am sure something is draining ur battery, most probably background syncing such as FB, etc ... better check on those ..

its been tested .. both 256hz and 500hz plays no significant difference in battery drainage ... some report totally the same ...

did u enable ur Data Network Mode?

yes of course, darky's installer is now a standalone installer, can be installed from any platform ... but in ur case, best to use the wipe[ version ...
if u r new, i would suggest u stay on official asia firmware dxjpe .. play around .. slowly explore, research and get urself a benchmark then only proceed to custom roms ...
jumping too fast will only come out questions like the fast few pages ...

this is weird ... my case was i forgotten to enable data network then my mms got stuck and i panic-ed .. hahaha

congratz on ur new phone and welcome~! ...
go check out XDA forum captivate version, everything u need to know is there

this was posted 2 to 3 pages back ... go have a look ..

above ^^

no idea which is better ... but it depends on region and wat type of rom suits u ...

speedmod k12m is out ... might wan to check it out ..

yea one of them is me, and that was while i was using official firmwares of DXJG4 and DXJPA, even last up to 3days+ ... but for custom rom no, coz alot of customization and optimization implemented, for the speed u have to sacrifice something else ...
17hrs for me is good, and usually my phone can last even longer .... brightness set to low, no background sync, disabled data network, super duper heavy texting, roughly an hr calls daily ...
its li-ion battery, just charge whenever there is a plug and charger with u, it is safe to do so ... but dont let the battery to go under 10% which is unhealthy for the li-ion batteries ... lazy to dig out the thread about li-ion batterys, sorry dont have the source ..

1st question, y do u wan to use JPO? instead of the newest official firmware of XXJPY?

just imagine a PC ... if u overclock, it works great but produced alot heat too but no fear, u can install ventilation fans or even water cooling systems but for a phone .... if u underclock, phone consumes less battery but if u r a gamer or heavy user it might slow down the speed so ... best is stay at default clock, best of both worlds as long as its smooth, nice and frozen yogurt like ...

about the JPA wifi modem update .. its a fix by hardcore ...
http://forum.xda-developers.com/showthread.php?t=885903
both update modem files of DXJPA and XXJPY is inside so u can switch and have a test urself ..
i am using the jpa fix without any issues on my specs below ...

Some info, through my own experience and also reading from other threads and forums ... no sources coz i read it last time ...
Linux is an OS which is superb for developers, its free source and have a very good ram management. So as Android is based on Linux, android inherited the good ram management as well. If ur ram manager shows u r using alot of ram, just leave it to the OS to handle, it is recommended not to use any task killers. The OS will try to calculate the best fit of ram usage for u, all u have to do is clearly/completely close ur app if u have done using it to free up immediate ram, even if u dont do so, after some amount of time the OS will just kill it for u but of course the app gotta run in the background thus eating up battery before it is closed. There are some custom roms and kernels that optimizes this ram handling as well, so u can try it out and can be found at XDA forums.
Another thing is safe up ram is to ensure u dont have any background sync, disable them or set it to the longest time limit it has (unless u r really active or required), this could save up battery.
Save battery by using low brightness, since i got my phone the brightness setting is manually set to around 10%. I dont like the screen being too bright as it hurts my eyes (high astigmatism ), this of course is altered at different environment or usage. Some said switching to GSM from HSDPA/3G helps too.
Smoothness of phone, is it already confirm that the latest official firmware XXJPY is the fastest and silky smooth rom, thats for those who prefers to stay on official roms, take note u do not have chinese/malay as it is europe firmware. No worries though u can extract and manually install them easily. For custom roms, most of them are based on JPY base, different developers have their taste so u may wan to try them out one by one. What i did was each week different rom till i get satisfied with one of them. For those who wants to stay on asia firmware, there is one half-customized rom based on DXJPE in XDA, so u might wan to try that out too.
Hope this helps someone.

time to sleep after whole day of studying

i am in Guildford, already quited GG ... punishing myself for spending too much time on it last time .. hahaha
anyway, end of this month i might go for a UK backpack tour ... when my exams over .. hehe

http://darkyrom.com/community/index.php?th...got-better.356/
read the post .... one of the question u asked is highlighted in the post ... and it was released i think an hr ago? ...

just leave it and u can either flash with odin or cwm ... all speedmod speedmod versions are interchangeable, only for version k10+ and above ...

U can try z4root or flash cwm.

I think so since v8.0 already had them.

To those who flashed to v8.1, rmb write caches and try market.i think gotta reroot through cwm again.

if i am not wrong, u dont need to ... darky have created a script to revert everything back to default then only start applying, but just disable them just to be safe ... darky v8.1 wipe version already have known issues so use the no-wipe version, i am gonna stay on v8 and start check back when my exams ends ... night guys

u can get it from here ... credits to Insanity creator, nitr8
http://insanity.rollus.net/

its the facebook app itself that is causing a problem ... either use default browser or a good browser from market and login through that, can even set to full desktop mode ...

i use google pinyin ... simple easy and works like a charm ..

another easy way ... install any moded kernel, and viola! u got cwm! ..

did u press the 3button combo long enough? ... take off battery, then put it back and make sure u press and hold on Volume Down + Home button and power button. Dont let go till screen starts up, some times it might take roughly up to 30secs of holding ... nite guys ...

@holypredator,
once again, no one telling u a solution is because we dont know either ... and maybe u should take the initiative to search for one and not to find cases to support ur problem. Different ppl have different usage, my GPS is working flawlessly in the place where i am now, using google navigation.
GPS issue is more towards the hardware, someone here opened up his SGS and fixed the chip connection and reported to be working very good, u can either try it or an alternative, sell ur SGS, 1st u can stop complaining and doubt ppl's comment, 2nd get a standalone GPS device or the Asus Garmin phone which is cheaper or even an ip4 since i heard m'sia officially start selling it already!
Once again, u cant generalize the whole population through just a measy single sample on hand. Different manufacturer and different design has his advantages and disadvantages, android users uses both and exploit it to their advantage. cheers mate.

Added on January 18, 2011, 8:13 pmbiasa la ... hilang for some time, then come back with complaints and say ppl no give him solutions , as if we r all both the hardware and software developers of this phone ... its a known fact that some devices have GPS problem, yet still cry over it every single time ...

btw, guys, i havent try this personally.. did anyone tried the gps fix in either sgs tools or toolbox? heard it changes the script line which helps in asian countries. I am too far away to try that and mine is working great.
