stock one uses RFS. speedmod doesn't change the file system but you can choose the filesystem you want in recovery mode (JFS,ext4)

I once used JFS filesystem and it was super smooth, smoother than ext4. You guys might want to try it. Just disable any lagfix you have(if you have one) by going to recovery mode, and then select JFS.



I don't know where he got hardcore's kernel that contains factoryfs.rfs but if he goes to http://forum.xda-developers.com/showthread.php?t=822756. Download the CWM version (speedmod-kernel-k12l-500hz-CWM.zip) or odin version. Flash it. Both conatins zimage but not factoryfs.rfs & param.lfs

True, no need to be rooted. You can choose to go with odin route or CWM route. Are you on official firmware?


Disable voodoo and tweaks that you may have enabled first. I think it is a good practice to disable them. Then download the odin or cwm version, put it in sdcard and flash away.

I have just switched from SO kernel to speedmod just now while typing this

If you can go to download mode (volume down + home + power button), no need to do the fix.
You also must backup /efs folder. store it somewhere safe (your computer, dropbox,etc)

Read this http://forum.xda-developers.com/showthread.php?t=723596 and understand it.

Never. Just follow the procedure carefully. It is very reliable.

First and foremost, it is extremely hard to brick galaxy s

Always put CWM update.zip and darkyy rom in internal sdcard. if you put it on ext sd card, it will located on /sdcard/sd folder - it won't work.

ext4 is safe and reliable because it has journaling system, unlike ext2.

I'd like that one too. But so far only for gingerbread. need to be patient with supercurio and cyanogenmod team

That's odd. I use it myself but have no problem like you said. How exactly did you install touchwiz gtg?


I used to enabled it but not now because I find it to drain battery alot. Like some one said, try rebooting and install the BLN control app

Which lagfix? Using ext4 instead of samsung's stock RFS will give you extra read/write speed that comes from inherent advantage of ext4. There will be no difference in smoothness (like swiping the homescreen left and right) but for app that uses a lot of read/write, database(like newsrob), installing app(when restoring app from titanium), you'll see huge difference.

It used to be that ext4 drains more battery and wears more than RFS. But as someone here quoted hardcore's statement about the optimization he made to ext4. If that is true, there is no reason to not use ext4.

All I can say is recalibrate your battery - drain, full charge delete battery stats using sgs tools app.
Go to Settings > Applications > Running Services to see what background service is running
Install os monitor too see which app is causing the cpu load.
Try different modem. Different area gives different radio strength, thus better energy efficiency. Some modem like JPP may be better but consumes a lot of power. This is a guide from pele78. Try different modems and see which one suits you the best.


excessive use of task manager may lead to more battery usage. only use it for misbehaving app. It helps for short term only. I used to install autokiller(not a task manager, but it manages the minimum limit of free ram for froyo) to increase the smoothness of the phone. I don't know how relevant it is now since the advent of speedmod and others. I don't think many people in xda uses it anymore. Maybe because we got bigger ram from speedmod (339MB)

Very true. Even if it happens, in xda, they use hairdryer and some homemade jig to go to download mode when their phone bricked.

Added on January 15, 2011, 3:39 amRFS - Samsung crappy file system
EXT4 - build upon the reliable and most used in linux - EXT3 file system. It is open source, one of the better speed (at least in benchmark) and heavily developed.

EXT4 FTW

By downloading android sdk. Link

I think is is better to narrate eveythting that you did. It will make it easier to point out where the problem is and give you the solution.

Firstly, you know you are using Froyo, now gingerbread right
I think 17hrs with thhat kind of usage is quite ok. What do you guys think?
galaxy s has crappy gps chip. Try flashing different modems to see which one is best.See this guide from cypher guide

But the new froyo will cut off power once the phone is fully charged. It will drop to 99% even though the power cable is still plugged in. So I think just wait 5 minutes before deleting batterystats

If you have "terminal emulator" app (or similar ones) installed on the phone, open it and type
& su (press enter)
#remount (press enter)

You'll have the /system writable
If you know some linux command kungfu, you don't need to pay app like root explorer

# cd /system/app (changes directory)
#ls (lists down all the files)
#rm /system/app/whatever.apk (deletes it)
#cp /system/app/whatever.apk /system/app/whatever.apk.bak (or you can rename the apk to .apk.bak. bak files basically means it is uninstalled but you may it back later)
#mv /sdcard/apkIwant.apk /system/app/apkIwant.apk (copies the apk from sdcard to /system/app folder

Or you can use adb. It is easier because you can copy and paste rather than typing on the phone. You need to install android sdk and get its adb first. I use "wifi adb" app so that I can adb wirelessly w/o usb cable. Once phone is connected wirelessly, use the command in this page http://forum.xda-developers.com/showthread.php?t=843019

Am I too late to welcome you? I'm new to this thread too btw!

Is darkyy's website seems to be slow? I think too many people are accessing his website. Maybe you guys should check out other roms too. You should try Doc and Stefunel's kitchen. Unlike darkyy's which packages everything for you, doc's kitchen lets you choose which app, modem, themes you want. It's really cool.

doc's is one of the oldest rom cooker in the forum. Kitchen: http://romkitchen.org/sgs_v1/ Forum link: http://forum.xda-developers.com/showthread.php?t=817703

Anyhow, these rom cookers do this in their free time. They are not paid with a salary. Even though they do not ask for donations, people are giving them and this them the motivation to continue forward.

If one doesn't like a rom, just switch. There are other pro cookers like doc and nitr8.

Yes it should.

Apk from insanity should only work with insanity rom only.

It is a new feature of froyo. Once the phone is fully charged, it well disconnect by itself to prevent over-charging.

Jz out of curiosity, downloaded Darky 8.1 as wanna see how the bootanimation. I must say.... THAT is absolutely CHILDISH and Downgrade the SGS... it is not because of Transformer, it is because of the DARKY ROM wording, Custom ROM Guru been in the field for so long, i have not seen DOC design something which put his name there.

Would try to get a snatch of it if i can find another camera to do it.

No wonder some of u who upgraded to 8.1 complaint about the bootanimation.

[/quote]
FWIW, it is just a boot animation. The only downside is maybe the ugly bootanimation will not appease your non-android-using friends. If you want to show off, you'll want a cool one right?

BTW, in my personal opinion and observation, his attitude does indeed a bit childish. That is why I avoid his rom and go to other pro and experienced rom cookers.

Bottom line, if you don't like it, change the boot animation or switch rom. It takes no more than 30 minutes.

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....Wow..just left the forum for a day and its already 39 pages.

Alvinz....
after i install speedmod k12l, battery is getting better. Now can last for 20+ hours... Thanks anyway for the advise on how to maintain the battery.
Btw, no wonder ur batt can last up to 2 days....So I got the wrong info then...

Enjoying my SGS so much...Luckily I made the right choice for not buying Iphone4.

Cheers

speedmod N version is out already. I switched from super optimized kernel to hardcore's M version together with switching from JPY modem to JPP modem. I got excellent battery life. Zero percent battery loss when data is off (at night).

I don't know if the improvement is made by switching to speedmod alone or together with the modem. I used JPP modem with earlier version of speedmod. I can say that I got better call quality and gps navigation than JPA modem.

Link to JPP and other modems here: http://forum.xda-developers.com/showpost.p...postcount=14434

Although it is from Doc's thread, I use it for insanity rom and it works just fine. Should work with darkyy's too.

For radio signal and gps performance, see these threads:
Radio: http://forum.xda-developers.com/showpost.p...postcount=11945
GPS: http://forum.xda-developers.com/showpost.p...postcount=13293

Depending on the region/area, you may get different performance. So my advice is to try all of the modems and see which one suits you best. YMMV.

Added on January 17, 2011, 8:07 pmMaybe, there was a bit lag for a few hours of usage. But even now, there were few occasions where I experienced some delay. About to test playing asphalt now.


update: absolutely no problem with asphalt on hardcore M version. But I have applied ext4 lagfix. On SO, I didn't apply any lagfix.

They will not be affected.
No need to rename. When you are in recovery mode, choose "install zip from sdcard" and then "choose zip from sdcard"

Use volume rocker for up and down, back button to select.

flash cf-root to get 2e recovery. Link: http://forum.xda-developers.com/showthread.php?t=788108

I think it is better to flash using CWM than odin. It is very hard to make a mistake if you go that route. Next time, make sure you have 2e recovery. If you don't, flash the cf-root to get back 2e recovery.

You are right, both needed odin. But once you are on 2e recovery, no need to use odin anymore except when you want to flash back to eclair JM8 or something.

Yes! Custom ROMs are many times better than official roms. samsung may be excellent in hardware department but they give us touchwiz??? There were some aspects where I find TW does few things really cool but overall I feel it is very unpolished when compared to htc sense.

Forgot to add. The zero percent loss is over 3 hours . Will test overnight with BatteryFu by toby kurien (which I discovered just now) http://www.appbrain.com/app/batteryfu-batt...urien.batteryfu It can schedule mobile data and it has night mode so that it will automatically switch mobile data on at preset time.

may I suggest installing osmonitor? It can show you which app is using the cpu.

There's a thread in xda that shows the hair dryer method and homemade jig. Try a search over there.

I doubt it is bricked. Try and flash stock eclair like jm8 using odin.

odd. Have you tried going into download mode by adb method? pull out the battery for 10 minutes prior to this.

If still unsuccessful, you can use the hairdryer method.

I can name three things where samsung went wrong with sgs:
1. Lag
2. Gps
3. Build quality

- SGS had a horrible lag and sluggish performance due to usage of poorly written filesystem (RFS). It is now greatly improved in the froyo 2.2.1

- samsung uses a second rate gps chip. However, mine works so so. I got 20m accuracy on the road. Remember, a gps lock means nothing if the phone cannot maintain connection. To truly test the gps, you'll have to test it on the road. The latest 2.2.1 also has helped a bit.
I use voice navigation feature in the phone and it flawlessly helped me to to my destination. Unfortunately, I required a bit of fixing to achieve the best possible gps performance. You wouldn't care what chartcross' gps status says if the phone can give you what you want - navigation, right?
FYI, Samsung nexus s has a better gps chip. Probably they have learned a lesson. Anyhow, such problem shouldn't have existed in such a premium phone. Same goes to iphone4 with its external antenna.

- Plastic case? They shave off few grams and make it light. Some people do not like it because it will feel cheap when holding the phone. But I do not mind it at all. To me, the super amoled screen is just way too gorgeous too look at and it outweighs the cheap plastic.

However, I don't think you've wasted 2.6k on the phone. Try and learn what it can do and you'll be surprise!
Also, don't take mainstream reviews with a pinch of salt. What you should listen to are user reviews.

Or go to Settings > About Phone. Baseband version shows what modem you have.

Depends on what flash. If flash advertisement, ok. But if the whole website is flash, then it will be sluggish.

Added on January 18, 2011, 7:26 pmIt is gps chip (hardware) issue. which kind of modem you are having also affects gps performance. I have posted a link on a review made by pele78 in xda developers. It is just a few pages back. Try each one of the modem and see the result.

edit addon: I'd like to re-emphasise. Fast lock means nothing if the phone cannot give you turn-by-turn direction. Try different modem and see which one works best for you.
If wifi issues, then it is the modem.
