Hi all...
2 days back i unlocked my bootloader
Now i have FXP 137 Kernal and using Jelly venila based on CM10.. but Prior to that i took a nandroid backup with Rage kernal and Stock ICS 4.0.4 with .431 firmware..
*Now if i restore the backup will kernal also be restored or simply the Rom???
*All kernals work on any roms or is there any limitation in it??
*Can kernals be flashed with phone itself (like flashing custom ROMS in CWM) without needing pc???
*Are there other Recoveries like CWM ? if so what is their advantage ?
*after a full wipe/factory reset, can recovery be accessed just by flasing kernal only?
*Clocking depends on kernal or Rom or both??
sorry for asking too many questions..these are in head..
i would be realy grateful if anyone answere these....
thanks in Advance

*No kernel won't be restored, you will have to flash it manually
*Not all kernels are working, check the thread of the rom, which kernel is recommend!
*You need a pc and the easiest way to flash the kernel is via flashtool
*Yes, for example Amon Ra, but I don't know if it's available for our devices...
*Yes, most custom kernels have cwm built in, so you can enter even after factory reset or after formatting /system
*Overclocking depends on kernel as far as I know, but it's dangerous and your phone could brick (overheating, etc)
If something is wrong, correct me

*it dosen't matter. Personally I flash the kernel prior to flashing the rom.
*Governor is basically a setting for managing the frequency of your processor depending on different values in different governors (try googling about different governors like- smartass,ondemand,lagfree etc). In my opinion you shouldn't go above 1.4 Ghz, you can go above this setting but your battery efficiency will drop and also you risk the chance of burning your processor. Your phone should be overclockable to that value but I have read somewhere that each chip is special to a phone.
I feel that 1.2 Ghz is a safe value for my phone and is fast enough for me. You can try it youself by downloading no frills cpu control from playstore and setting your desired frequencies.

i have tried many roms but is it safe to use rom with overclocking ace ?? pls suggest roms without oc !! thanx in advance !!
"overclocking" and "safe" cannot be use in the same sentence. Its always been a risk of damaging hardware with overclocking. And it doesnt depend on rom, it depend on kernel. Most of the rom here doesnt include overclock kernel by default. But even if it does, u can just reflash with other kernel u like

Hi,
kernel is the main system core of every LINUX or UNIX system, even on Android (its something like non.consistent linux...) which controlls the whole hardware available on system - e.g. display,processor, memory, wifi and bt and so on.
As you wrote, your system has stock kernel - standart delivered from SE.
You can use any kernels from XDA for X10i, there are not so much differences between them. The main thing is the CPU governors. Stock kernel doesnt have good CPU governor (called "ondemand"), so it drains battery all the time. Thats the one thing related to kernel. There are also some optimalizations and so on like undervolting, possibility to load external harware support drivers an a lot of other stuff.
But for begginner, you would probably appreciate only the CPU governors, because of battery life.

I hear doom kernel is good, but it has wifi problems, especially with the latest version. Which kernel would you recommend?
Try doomkernel or zKernel, but u must know that some kernels are for locked and some for unlocked bootloader. U have doom for both.

How do I check?
Also if I install any of these custom kernels, would I be able to restore the original SE kernel if needed?
U can check it with s1tool, find it on this thread (step for unlocking bootloader). And yes, u can return ur stock kernel, with flashtool. All info u can find on this thread:

If you havent done bootloader unlock, you have locked bootloader Or test as described above
And yes, if you will install any custom kernel you are still able to load original kernel from SE. In case you will delete locked bootloader image; the stock kernel will load instead. This is on locked bootloader, dont know if this also on locked kernels.
No, DoomKernel doesn't have WiFi problems...I think you said it because once you have DoomKernel installed on your phone, you must flash and adittional file using Flashtool that is called Wifi Module, and everything will be fine again..

You dont need to backup stock kernel, it cant be erased (only after bootloader unlock).

Yap, on locked BL u can't erase stock kernel, u don't need to backup.

I guess that you can find a complete tutorial on FlashTools topic under the complete FlashTool guide.
Long story short:
1 Install Flashtool and put desired kernel file inside the firmware folder (which is located inside flashtool folder)
2 Connect phone with unknown sources and USB debugging checked on and check if its recognized
3 Click the flash button (the one with the little thunder), select the kernel file
4 Follow FlashTools instructions (it will show up after you select the files and hit ok)
5 ??????

That additional file called WIFI module or WIFI fix must be flashed via Xrecovery, because it's a zip file. With Flashtool you flash just FTF files (FlashTool File).
Doomkernel (V06) are good, Ferakernel also, ThJap th n5-1... This are kernels for Stock based Roms.
For non-Stock based Roms, like CM 7.2 AND CM9.1 based Roms, you must use kernels which are based on that Roms (FXP kernel, Amin kernel...)
That rom that you were flashed (Donut 2.2.9) is one of the best Stock based Rom. You can use Doomkernel v.06 with medium OC (Overclock) 1113 Mhz. First download Doomkernel on PC, and put that file in Flashtool/firmware folder. Than download WIFI module for that kernel and put on SD card of your phone(every kernel have specific wifi module). Flash kernel via Flashtool, when finished, reboot into Xrecovery ( when you power up your phone and blue led lights up, keep pressing Back button on your phone). Choose Install custom zip, than find your downloaded Wifi module and choose to install. After that, choose Reboot option in Xrecovery and enjoy...

Is there a way I can overclock my beloved x10? What are the risks in doing so?
Sent from my X10i using xda premium
use doomkernel v06 on stock rom or rom based on stock rom.... u can overclock upto 1.2ghz using inbulit app or using set cpu or antutut cpu
the risks of Overclocking are that not all devices can handle it .
and could cause sudden reboots etc when the cpu's "drowning" in data
and ofcourse battery will drain faster (not that i notice it that much)
to be honest i havent read or seen or even encountered any "real" risks can be annoying if your phone reboots but you can still undo or even try a lower OC speed.
i believe its most important factor in weither you can or cant handle is heat.
(pardon my english) a phone releases its heat passive meaning if you put it out in the sun chances on reboots will be higher.
http://www.pcadvisor.co.uk/news/mobile-phone/3255360/should-you-overclock-your-smartphone/
check this out its a good explenation i found.
I decided to try for myself and I now use DoomKernel v06 with SetCPU I don't really see a point in overclocking my phone though haha but can underclocking it have a negative effect when it's just on standby when I'm at school? And I'm not sure what governer to use hahaha

Underclocking
When phone is in standby mode it doesnt need any underclocking it goes automatically into deep sleep. This cpu mode saves lots of energy.
Most of custom kernels already handle it.

Depends on your liking. Like Battery Lifespan, performance and so on. For Knowing more about governors and their specialties,
In This Thread, it explains Things about I/O schedulers, Kernel, Governors and related information.
If DooMKernel versions for locked bootloader, i recommend 1113MHz as optimal and best for your X10 because moderate overclock, and compatible to most Custom ROMs. You can get it under my signature link.
Hope helps.

If I flash the DoomKernel-1113 kernel, is my phone automatically overclocked or do I need to set clock speeds after downloading SetCPU etc?

Setcpu is to change governor and increase frequency. Yes you need. Because your original frequency is 998MHz.

Please note that DoomKernel V6 has two versions: For Locked Bootloader and Unlocked Bootloader If you're looking for locked bootloader version, i got it linked under my signature.
While DoomKernel V6 for Unlocked Bootloader, link here Place the ftf under flashtool subfolder "Firmware" to flash the kernel wifi modules can be flashed via Xrecovery (in case Wifi not working)
There're 2 ways to get back stock kernel:
1) [LOCKED BOOTLOADER] Just full wipe, clear cache partition in xrecovery will restore your Stock Kernel as long as you didn't unlock your bootloader. Note that these actions will remove all your user and system Data.
2) [UNLOCKED BOOTLOADER] Flash the Stock Kernel for Unlocked Bootloader via flashtool. Stock Kernel Link for Unlock Bootloader Here. Remember to place the stock kernel FTF file under flashtool subfolder "Firmware" to flash the stock kernel then flash the wifi modules (if wifi not working) via xrecovery
Hope helps. Cheers

Hi,
Mine runs on 245Mhz and 1.114GHz with no negative effects. No noticeable drain on battery and no freeze effects.
When I choose 128Mhz as the lowest frequency it takes a while to get going. ie sometimes I have to press the wake button twice.
When I clock it to 1.2GHz I start to get problems with the program freezing/jamming up. Make sure you don't tick the "apply on boot" straight away until your happy with the stability of your phone.
Hope this helps.
I'm using 128/1036 Mhz. It's just that little bit extra which makes your phone super smooth and you save the extra battery life with the 128Mhz cap.

A few weeks ago i flashed Rafael's kernel, after a few days the phone rebooted during a call and bootlooped. I had to flash with odin back to stock kernel.
As i read, Rafael made a version with E3 recovery.
Which is better for my phone? E3, CWM or RZ recovery version?
I have a stock ROM, baseband XXLA2.
I use ext3 with Link2SD.
I think there are no more important infos.

Hi,
You can flash back to stock kernel, when you flash the whole stock rom.
The first warning? Me too can not understand.
The second: when you want to restore a backup, which you backuped with an earlier version of the kernel, then you will (soft)brick your phone.

Hi brother,
You can flash the E3 one....the CWM and RZR have some ext 4 problems. Rafael himself recommends the E3 version. There is a bug in the kernel...(rebooting). He will look into the matter as and when he gets time. Till then if you dont have problems with a few reboots, then use the kernel or stay with the stock one. :thumbup:

Is the Jelly Bean 303 compatible with E3 version kernel? I tried to flash this combination but the phone booted to a black screen. CWM version seems to boot normally (albeit is a little unstable)
then with the stock kernel can not use link2sd? because I'm using now, then what? if I wanted to go back to the stock kernel as I do? and what precautions should I take first? and if I wanted to try the latest rafael's kernel What should I watch?
may not understand what this warning means?

Yes, that kernel has problems with random reboots and there is no solution at this moment. However, the issue is not as bad as it may seem as "random" literally means random - you might get 3 days of stability and then 3 reboots on the 4th day. Anyway this is a relatively minor inconvenience and will be sorted out soon I'm sure. You can always go back to the stock kernel through Odin

Oh and if you do flash Rafael kernel, get the E3 version, the one that doesn't format system partitions to ext4. Or else you risk of soft bricking the phone on any of those random reboots I mentioned in the earlier post. Totally not cool
you guys are lucky coz you successfully flash the kernel.. but ME after flashing...
my phone always got a softbrick but I follow all the intructions step by step

That's beccause you use CWM or RZR recovory instead of E3(stock recovory).
Flash stock rom trought Odin and everything will be allright !
no! I even use e3... and same thing happens. T.T

After a few days of testing this is howto avoid reboots on s5830i with Rafael's kernel:
1. Disable 156MHz frequency - allow to scale CPU from 312 to 832Mhz. Best way to do this is to install "No frills CPU control" from google play
2. (optional) Increase voltage in kernel sources and re-compile it. This is easy if You have Ubuntu as scripts are prepared for this system. My values can be found in one of my previous posts.
After doing this I had no single reboot. Works 100%. I'm not sure if step 1 without step 2 will help much, but can guarantee that doing both will solve Your problems.
Quick backgroud (what I suspect):
1. Not every phone is ready for low voltages introduced by rafael. Some of them needs higher voltage - this is first source of reboots
2. It looks that some of s5830i does not like 156MHz, especially during call. Rafael has added this frequency for longer battery life, but as we can see it was not a good move for all the phones.
Bro it is important bcuz it is the only successful kernel for galaxy ace s5830i...u can get that on any custom rom

I can confirm this, after disabling 150mhz speed the phone got mostly stable. Still reboots sometimes under heavy app load but that is to be expected I guess, it might be caused by programs too

Install kernel and modules first
Then install custom ROM without boot.img
Then flash modules again
I own a GTi9300 4.1.2 XXEMC2 rooted but still on stock (didn't find any advantage in any custom ROM so far) i rooted it using CFautoroot.. I didn't install CMW yet using ROM manager, but im willing to once i find a kernel that will let me overclock my phone.
So any adviced Kernel that will work on my phone to overclock? Currently SetCpu only allows me to underclock :/.
Thanks in advancee
N. B: I DONT OWN A MEMORY CARD IN CASE ITS NEEDED TO FLASH A KERNEL
check the development section for compatible kernels. all of them allow OC

Siyah Kernel up to 1.8 GHz. What app is great is stweaks it allows to select how many cores u wanna use also has a build in sound equalizer and many other cool things. But u need Siyah kernel installed for it to work.
