[Q] question about overclocking

Im planning to overclock because im experiencing some drop frame rates when playing advanced games i.e gta3 and bankstab. I downloaded atuntun cpu and the maximum I could go up to was 1024 MHz. Is this really the limit?! My phone I rooted.
Im thinking to download setcpu but im wonderimg whether the maximum I would get up to is 1 ghz or could I go higher?

You need a custom kernel to enable overclocking. To flash a custom kernel you must unlock your bootloader

Oh... ok.
A few more questions then:
1) Will increasing the MHz of the cpu make the games play more fluently? (e.g. gta3, backstab etc).
2) By unlocking the bootloader and loading a custom kernal, will I still be on stock ROM?
3) Does the phone need to be rooted again after unlocking the bootloader and loading a custom kernal?
4) Will I be able to update OTA when 4.0 comes out for XPlay?
5) Can I go back to the original state of my phone after unlocking it?

1) Yes, for pretty much any game (although some may depend more on SD card speed)
2) You'll still be on stock rom unless you also flash a custom rom
3) Not sure but possibly. It's incredibly easy to root with an unlocked bootloader though
4) Only if you use the 'Testpoint' unlock method
5) There is a file that can be flashed to relock the bootloader but I'm not sure if it works with the 'Testpoint' unlock method. You can also reflash the stock firmware which restores all factory settings (except bootloader status)

Can anything go wrong whilst unlocking the bootloader and installing a custom kernel? If yes, will it brick my phone?

WE HAVE TO SAY YES HERE.. however it highly unlikely and is almost always possible to fix.

just use dooms kernel v11 im stable at 1.4 and games run smoothly except mc3 taking freaking 10yrs plus jus 2 start a match!!!!!!!!!!!!!
its easy to unlock this bootloader ay. if you can follow instructions and got common sense then every hacking step you take should be a breeze

ok. im planning to unlock my bootloader and flash the doomkernal. although on this page:
http://forum.xda-developers.com/showthread.php?t=1176502
under notice, it says:
[ NOTICE ]
since i have changed the kernel version string stock wifi modules will no longer work on my kernel...
if u try to enable them on new kernel (v7 onwards) u will get "ERROR" while starting WIFI...
i will be providing wifi modules for my kernel which HAVE TO BE FLASHED VIA RECOVERY for wifi/bt to work correctly
stock wifi modules will also be provided which again will have to be flashed via recovery if u want to return to stock kernel OR if u revert to older v06 or lower kernels
What does this mean? Does it mean my wiFi will stop working?

Just means that each time you flash a new rom, you'll have to flash the wifi modules provided in the doomkernel thread

[Q] Going mad!!

My wife is the proud owner of a htc wfs
I made the mistake of uploading it to 2.3.5 (she liked it better 2.3.3, the phone was smoother)
What do you suggest i should do for downgrade ?
I am willing to unlock the bootloader, install cwm and the then flash the stock 2.3.3 ? (am i getting this right, don't wanna screw up - divorce on the way kidding)
Advices ? (is there a simple way to do all this ?)

Unlock boot loader, take s-off, root and get recovery & get the smoothest and stablest sense 2.3.3 rom.

you can install the gaming rom which is based on android 2.3.3 after you unlock bootloader, root then cwm.
But you can leave it at 2.3.5 by flashing any 2.3.5 rom with an overclock kernel. After you overclock, you'll find out that its faster, smoother and better than the old stock 2.3.3.

ok, thak you for your quick answers , i see that :
1. have to unlock bootloader (using htcdev.com)
2.install root, than cwm
3.this is bugging me , how can i install a stock version of htc 2.3.3, after root and cwm , is that even possible ?
I saw a tool that you can flash from cwm recovery and control your bootloader, the last option being supervision (activate it and then run ruu ?)

Last Bit
Step 1: Download the stock 2.3.3 Rom from here http://shipped-roms.com/index.php?category=android&model=Marvel
Not sure which one it is but I know its now the bottom one that is the one I am running 2.3.5.
MAKE SURE IT'S A .ZIP FILE ! Since your using CWM.
Step 2: Place the .zip on to your sdcard and reboot into recovery.
turn off the phone -- take battery out -- put battery back in -- hold volume down and press power button -- then hit recovery.
Step 3: Wipe Data/Factory Reset, Wipe Cache & Wipe Dalvik (Advanced Menu)
Step 4: Flash zip from sdcard, Pick your zip file and after its finished reboot your phone and you should be fine Enjoy !!

The index has almost everything you might need to root, unlock, or whatever it is you want.
There are links there to rooting guides, as well as to ROMs - custom, overclocked, Sense or Senseless, depending on your need.
If I were you, I'd flash this one. It's Sense 2.3.5-based, but it's really fast, smooth and looks better than all the other Sense ROMs I've tried (you can also customize it by flashing some of the other options which are linked to in the ROM's thread, such as a transparent app drawer (better looking than regular Sense and no need for a replacement launcher)).

quick question, should the phone be loaded at 100% ? or the battery should be somehow calibrated ?

Better off using a custom stock rom. Much faster.

No need for the phone to be at 100%, though it is recommended, so you don't run out of battery in the middle of flashing/rooting.

[Q] [S] Future OTA if I root with locked bootloader?

Hi all,
Just got my Xperia S and really love the phone with fantastic design and awesome screen. I really intend to gain root access for my phone to troubleshoot the battery drain issue further (and using some app for better control over the setting). Here's a few queries I have (and some partially answered by some of my searches on the forum):
Will I get any OTA or official firmware update shall I just root my phone with locked bootloader? (I won't mess with custom recovery or ROM)
I suppose I could still claim my warranty. But is there anyway to remove any traces completely to prevent them from finding out? Just removing the superuser app?
If in the future I would like to have access to custom recovery so that I could flash ROM, I suppose I must unlock the bootloader right? (at least until someone gets a workaround for locked bootloader)
The tool I will use for rooting is by Bin4ry. I am on the latest ICS firmware.

Yes you'll definitely get official update
To remove trace completely just flash an official ROM via flashtool (official fw can be obtained at dev section)
No can install some stock based Custom Rom and CWM in locked bootloader
Eg : XTX,dualcore,Xcream,etc
What you can't do is flash a kernel. You'll need to flash a kernel to install Cyanogen Mod or Paranoid based rom

Hmm, I guess I could get official update, just worry that I would lose root during the update. I think I could still try to retain my root using some app right? (LOL, I am a bit outdated about all these stuff - was using a HTC Desire where 2.3 is the best we could go)
I am observing that my screen is a bit yellowish throughout, perhaps I will send in for a warranty before I do anything.
Thanks for the reply. Really appreciate it and clear off some doubts.

[Q]CWM + Root

Hi guys, so i have my stock Xperia Play GSM and i wanna install a custom Kernel with CWM and then root the phone using CWM. Can you please tell me what is the best Kernel for games and also has the CWM built in. Do i have to do anything else to my phone before i can do this ? I unlocked my bootloader and installed Flashtool ...
Device: Sony Ericsson Xperia Play R800i GSM, Android 2.3.4 -> 4.0.2.A.0.69
Thanks !

I can't tell you which is the best, and I hope all threads starting with "best" gets locked. But generally you need 2.3.3 to root but since you already have an unlocked bootloader, you can install any custom kernel, they have CWM installed so you can boot into recovery by pressing the Volume down button at Sony logo. From there you can install a custom rom that is already rooted. You need the rom and kernel to be compatible with each other in order for the phone to boot.
If you want to just root the phone you need to down grade to 2.3.3 and use the root feature in flashtool. If you want to manually install clock work mod, after rooting, use the CWM installer version 5 from this link, the option to reboot into CWM in the program will not work BTW, you'll have to do it manually. http://forum.xda-developers.com/showthread.php?t=1437840

If my bootloader would be locked, would flashtool work ? I wanna downgrade to 2.3.3 but when i do so, the program get's stuck at 17% ... When i flash the ROM, do i need to check/uncheck any items ? Like kernel or bootloader ?

The flashing process can take time, wait up to 10minutes. Sometimes it can get stuck due to bad cable or other variables. Try plugin it in a different port, preferably USB 2.0 port, and with no other USB devices connected to your computer, keep trying and it will work eventually. Try a different cable as well.
Flashtool have to work with locked bootloader, which is needed if you want to restore a locked phone to stock. You don't have to check anything unless you want to specifically exclude it from being flashes. You should flash this firmware, its 2.3.4 but it has been modified to be rootable: http://forum.xda-developers.com/showthread.php?t=1591398
I thought you said you unlocked your bootloader though.

[Q] Why do you need "unlocked bootloader"?

I've done some research in to unlocking the bootloader for my Xperia Arc. I have yet to understand the reason why you would need to unlock it at all.
The official definition given by Sony on their website is:
Unlocking the boot loader allows you to put custom ROMs on your device.
Click to expand...
Click to collapse
However this is clearly not true. As I am able to put custom ROMs on my Xperia Arc without unlocking the bootloader (ie. I was on official ICS firmware. I flashed kernel to different version then root using doomlord's ICS root, flash back the original kernel then installing Ultimate HD 4.0 via recovery.)
I have noticed some other ROMs state they are for unlocked bootloader only. Is this becuase they require custom kernals in order to function? Is that why you need unlocked bootloader (because locked bootloaders can only accept official kernals during flash/boot)? Or is there a more in-depth reason?

To explain further, you can still install custom ROMs, but only ROMs based on stock firmware and using stock kernel. If you tried to install other ROMs like CyanogenMod you will realise that you can't install the ROM at all because you cannot flash the custom kernel that comes with it. What the unlocked bootloader does is allow you to install unsigned kernels onto your phone. Stock kernels are already signed by Sony so they can be flashed without unlocking your bootloader.
The kernels you have been flashing so far are all stock kernels so you can flash them with no issues. If you tried to flash a CM kernel you will get an error if your bootloader is locked.

Thanks. So I was right. The Kernel is (one of?) the reason you would want to unlock your bootloader.
Do you know if unlocked bootloader is required for SD partitioning on Xperia Arc? I had a read here http://forum.xda-developers.com/showthread.php?t=2126363 but something is confusing:
- Unlocked Bootloader (need EXT4 support, not allowed in stock kernel)
- EXT4 Kernel Support (most of kernels for Xperia 2011 have EXT4 support)

u dont really needed i payed 10 dollars to unlock it so i can use custom kernel to increase the performance of the phone,but still after 2 months after that i dont see any improvenments

Really? Went from Stock .587 rom to ultimate HD with stock .587 kernel and I find the phone can't handle more than 3 apps without slowing down at certain times.
I was actually considering unlocking so I can get an overclocked/custom kernel to improve performance.
What do you mean by after 2 months you don't see any improvements? Did the performance improve at first but now have gone back to similar performance of stock kernel?

If you don't know how to optimise the ROM then it will be as slow as any stock ROM. Don't say that the performance never improves after a certain time of usage. Please read up on the ways to optimize and improve ROM performance rather than assume that custom ROM is not good when you haven't tried optimizing it yet.

The base ROM is good, but it's the stock kernel giving the bad performance. Overclocking doesn't help much with performance so it's not recommended.
Like I said in my earlier reply, the ROM will work properly if you optimise it for performance, so don't say that the performance does not improve after a certain time of usage.

Correct me if I'm wrong but by saying "ROM will work properly if you optimise it for performance" do you mean flashing a custom kernel? (in which case you would need unlocked bootloader?)
Or do you mean an add-on like this: http://forum.xda-developers.com/showthread.php?t=1908269 ?
Or something else?

The only "optimizing" that u can do on a rom is removing the animations since overclocking is not recomenced.So i still find it useless.Even the phone app is starting slow.So in my opinion spenging money on unlocking ur bootloader is useless

So I tried "pimp my rom" and ticked all I thought I wanted but got a boot loop and had to reflash everything.
I'm keen to know what you mean by "optimising".

It can be as simple as installing and removing apps to running scripts that improve performance. I use Greenify to hibernate apps running in the background and I don't install Facebook on my phone. Only install apps that you use often because if you install many apps on your phone, it's going to take up more memory and slow it down.
