This thread is somewhat different from others. I am fully aware that overclocking requires a custom kernel however with the Application "Galaxy Tuner" my CPU on my SGS i9000 can go 1.2GHZ with a custom Voodo Kernel not supporting Overclock. I am not sure what method the guy uses and he only allows it to be used 2 minutes at a time, so I was wondering if this would be just as risky / safe to do as going into a new kernel and doing such.
If the first is not possible and I would have to use a custom kernel as it is safer, please PM me some kind of contact information as I am afraid I will break my Phone as I use a custom Voodo kernel + DArkys EXTREME ROM 9.X
Still need to know wheter or not it is safe to overclock the way the application "Galaxy Tuner" does or if its SAFER to do it with a custom OC'ing kernel.
If last, I need some help over Skype / msn

I wouldn't expect anything, just because people like me view it doesn't mean we know anything about it.....why don't you email the author of the app.

Exactly, views don't mean answers! It can be frustrating seeing a lot of views and no answer, but you must acknowledge that viewers may be looking for the answer themselves or just plain don't know. Be patient.
Well. Still, I am wondering about the overclocking that The application uses (Galaxy Tuner) because it manages to overclock a phone WITHOUT a custom OC'ing kernel. Hence i am wondering if it is just as SAFE to do as using a custom kernel.
If not, I need some guidance as I dont know how I can switch my kernel and update my ROM
The code to overclock existed on stock kernel sources apparently, it was just commented out.
When OC in this app is enabled, the CPU governor is changed to performance, and the clocks were changed. So I'd wager it's equivalent in terms of safety to a custom kernel.
Why only do the above for 5 minutes at a time when a custom kernel allows you to always have an overlclock? Just use a custom kernel..
I'm using a custom kernel to overclock to 1.2ghz and my battery is exactly the same as it's always been. I'm also underclocking to 100mhz with setCPU when the phone is idle so that's a big help. It's perfectly stable on mine but CPUs can differ so I suggest that if you do flash a custom kernel with overclock that you start lower and stress test just to make sure there are no issues. Also, don't save any voltage control settings as default until you have applied and stress tested.
Also, make sure to keep a spare kernel in zip form and always have backups.
I use super optimized kernel. Though I am looking for a 500-1000 HZ OC kernel. Any suggestion?
I don't know what method this app is using, but just due to my own paranoia I would say using a kernel with OC is safer. Too many horror stories of apps bricking phones due to small errors or badly written instructions.
Beyond that, it just takes experimenting. I am currently using DamienGTO's Ultimate Kernel OCed to 1200 and have had no problems with it, but there are a lot of high quality kernels available down in the Android Development forum. I suggest you install SGS Kernel Flasher from the market (a great app, makes kernel flashing painless and dead simple), download the newest versions of each kernel that says it supports OC, and spend a day flashing and testing. Just remember to disable any OC/UV, lagfixes or tweaks between flashings.
Hi,
Does any one know which Android Version Samsung OFFICIALLY fixed the stalling/lag issue for the SGS i9000? Is it even officially fixed?
Just that I'm recommending a phone for someone I'm not too close with and dont feel like loading on CM7 for a stranger
Searching only gives me millions of results for One Click and Voodoo solutions. I don't want to tell this person to go through these steps.
Thanks!
2.2.1 is pretty smooth and fast. 2.3.3 also, but there are issues with battery life and stuff that can be fixed but require knowledge. So, I think 2.2.1 ROMs are the best option for someone who doesn't want to deal with custom roms and kernels and rooting. Of, course a custom rom and kernel or just a custom kernel can make the phone not just smooth but blazing fast.
Hm, can you confirm that the Stallling issue is actually fixed from 2.2.1 onwards?
Specifically the problem when you click Market/Market > MyApps/Maps/Contacts and it takes ~30 seconds for it to load.
I'm not too concerned general chipiness/lack of finger-tracking smoothness.
Sorry for the paranoia , just that i hated the stalling before I was on CM7.
Officially? None. Samsung have repeatedly announced that users of their latest updates "will experience smoother performance".
They announced that with 2.2 and 2.2.1 and I'm on JVH and can confirm even JVH benefits from not running on the rfs filesystem. Yet they've never acknowledged a specific issue that creates lag, even though everyone on this forum knows exactly why and how to fix it.
Actually all stock samsung Roms run on rfs file system including the 2.3.3 ones (which means JVH too). The problems you're talking about are generally fixed by changing the file system from the stupid samsung's rfs to usual linux ones - ext4 or ext2 (ext 2 makes it extra quick in the GUI coz it quite improves the read-write speed) - everything opens immediately. Just stock 2.2.1 with changed file system will make the phone open the things you're talking about right away
Thanks for the replies.
So basically the problem exists for all Samsung ROMs, just to a lesser extent from 2.2.1 onwards. As proven by http://www.youtube.com/watch?v=g1B2fstyrRA, 2:13 mins. How annoying!
Hm, not sure i can reccommend an unhacked SGS
I would say 2,2,1 usable without any lagfix ,
Before needed a lag fix .
But ten million users on 2.1 dont know what needs fixing lag whats that ???
SGS 2 no lag .

Hi all.
I have been using non-stock ROMs ever since I got my Nexus One. I am really frustrated with the slow USB transfer speeds. Strangely, they appear only in some of the roms I've tried and never in Recovery:
CM 7 - slow (2MB/s max)
MIUI - slow
Hypersense - fast (~10MB/s)
Oxygen - fast
My tests were always performed with the same file, USB port and original cable.
Therefore I am assuming it is a kernel issue (CM and MIUI use the CM kernel). So is there any kernel I can use with MIUI that fixes this?
Thanks in advance!
Yes, it's indeed a kernel issue. Stock speeds were once even worse, bordering on 1MB/s.
Recovery always moves the files fast (though seeing 10MB/s is strange, I believe Nexus' HW maxes out below that).
Unfortunately, I don't know how to help you with the settings, it might be something more complicated than buffers allocation etc. But dbasabe might help you more - he's the developer of Sense kernel, so he can tell you if he compiled it with any specific switches/tweaks regarding SD speed.
I believe the issue is within the CM source, as only CM-based ROMs suffer from it. The workaround is to use the app Multi Mount found on the market.
Try the ICS roms--FAST

Yes, SD card trasfer speeds are faster in Texacise/MeDriod roms. However, ROMs are in alpha and have many other issues. I seem to struggle with network going off on its own and soft reboots .
The latest ones have network fixed--I use daily now. But, yes it is alpha.
However, most of these roms give some issues to some people. One key is preparation/study and FULL wipes.
Thanks for all the input guys
I guess I will stick to MultiMount for now as I really enjoy MIUI. I haven't encountered any issues with the app so far although there are a lot of negative comments about it.
Hey all,
Recently I tried out the latest Alien Revolutions and I noticed the RAM is 421mb total. Obviously I'm a noob but I'm assuming that the SWAP script is making the RAM so high, is that right? I did type in "free -m" in the terminal and it came up as Swap: 0...
So is it swap? zram? ram hack? Or just an amazing ROM?
Hei1125 says "RAM optimizations" in the change log.
The wifi doesn't work, but when you flash the kernel hei1125 suggests, it does work fine, but the total ram goes back down to the usual, near 350mb.
Any help would be greatly appreciated,
Sam

There is a kernel hack which gives back certain amount of memory back to the system (but sometimes at the expense of some things not working). So I think this could be the effect of the kernel memory hack.
Which kernel have you flashed? I believe that originally the AR rom contained vadonka's HOC_OTF_48.
kernel hack
Thanks for getting back to me. I asked the maker of the ROM and he said the same thing as you, a kernel hack. I'll do some research into what that is exactly.
You mentioned that the kernel uses less ram for the OS, does that mean that the ROM will have the same processor efficiency as other kernels without the ram hack? Does ram hack use more battery is what I'm trying to ask.
I'm not sure which kernel it was, I flashed the swiftextreme 48 2011 2011 kernel, it keeps the memory at 420mb total, although this has done nothing for my available ram, it's still at 195mb.
Thanks again
Alright. I've searched the forums for 4 hours trying to find different answers to my questions and I haven't had success in all. So, in case I'm that much of an idiot for asking a question that's been answered 1000 times, I'll be happy if you point me in the right direction instead of "politely" asking me to use the search button .
My GF bought an Ace which we were unable to root until we stumbled across the fact the 5830M differs from other models in some ways. We finally got it done yesterday with the help of this thread (I should add the her sole intention of rooting the phone was to expand her Ace's internal memory to be able to install more apps). and we are supposed to partion her SD card (32GB) today. However, after going through so many threads, and deciding CWM will do the partition, we are now unsure about wether we should switch ROM's or keep stock.
So, my question is: Is there any disadvantage of having a rooted phone with its stock ROM? Or better yet: Is there a reason as to why I SHOULD change ROM's?
Thanks in advance.
Hey there,
At this time, there are 3 custom ROMs that are truly different: Razodroid, Retribution ROM and the rest of the deodexed ROMs (2 or 3, I believe).
Let's take each on its own:
Razodroid offers the following:
EXT4 File System
Link2sd
New lock screen
Hard root
Bravia engin
14toogle
Galaxy SII CloCk
New icon pack
Custom bootanimation
Defult *ICS* theme
Ext4 script
Msg limit increased n skins added
Tweaks added
Miui music player added
New google play
All apps updated
New tw Modded
Busybox(latest)
New Launcher
ICS keyboard
Deodex
Zip Aligned System Apps
Sign all apk n zip
Swipe To Clear Notification
Battery saver Tweak
Better Performance
Battery Life increased
Faster SDCARD Read/Write Speed

In other words, it will bring you a slight performance boost, more juice, a different look and some (currently buggy/not so smooth) new features such as swipe to clear or 14 toggles.
Retribution ROM has less features. It's mostly about performance, but it's still in a beta stage, so there's more to come:
Smooth Scroll Mod
Build.prop tweaks
Flash Player pre-included
Beats Audio Mod pre-included
Updated libs and modules for better perfomance
Completely ad-free

Both of these ROMs come along with Rafael's kernel, which adds support to init.d, iptables and cpu governors, among other features. They're useful for running scripts at boot, using firewalls (e.g. DroidWall) and changing the phone's governor (as the name suggests).
Last comes the deodexed ROMs that have no additional features. As any deodexed ROM, they remove odex files, giving you some extra internal space (at the cost of a slight performance hit) and allow easier theming, allowing you to get, for example, an ICS (deodexed) theme for the S5830I (it's made by rajrocks, search for it if you're interested).
To sum it up, there are no disadvantages of having a rooted phone with the stock ROM. Actually, you have almost no reason to get a custom ROM unless you're interested in the new features they bring, especially that performance/battery tweaks can be applied using scripts or manually without needing a custom ROM, if you know what you're doing.
EDIT: You should however consider getting Rafael's latest kernel for the reasons mentioned above: http://forum.xda-developers.com/showthread.php?t=1818830
Very detailed answer. Thanks!
TBH, I think we'll just keep the current ROM (if it was up to me, I'd be tweaking the hell out of the phone) seeing that it isn't really necessary. If we do, we'll be picking option # 1.
Thanks again.
The only disadvantage of installing a custom rom (i think) is the bigger chance of losing your phone's warranty
