Hi. I have some doubts about this, I wanna try the last rom by nAa, and it ask for a unlock bootloader and nAa Kernel, my quiestion is: After doing that is there any way for getting back to the original kernel, I mean PC companion will work? and restore it like factory?
Thx!
Don't worry, you can flash anytime back to stock kernel, witch is here http://forum.xda-developers.com/showthread.php?t=1403808
Thnx, but I meant Mini pro u20...
Btw, if I have a Backup with Minicm7 by paul in cwm with stock kernel, if then I flash Naa kernel, if I restore the backup I had, it comes with the stock kernel??
No. CMW backups the ROM and its data. To revert back to stock kernel you just have to DL a stock kernel file from the site and flash it.
And the bootloader re-lock?
What are the benefits for having an unlocked bootloader, using a rom in stock kernel...
If you're using stock kernel and dont plan on using a custom kernel, there's no benefit.
The whole purpose of unlocking BL is to be able to flash a custom kernel. there are pretty whack custom kernels around which, naturally, are better than stock.
So, what are the benefits of using Custom Kernel?
My x10 mini pro is running paul-xxx's miniCM7pro version 17, and the result I got from S1tool were: SEMC SIMLOCK CERTIFICATE (that means I can unlock it right?). My question is can I continue the unlocking process, or do I need to downgrade my phone first to stock firmware?
I'm doing this for my brother so I haven't been much on this sub-forum.
Thanks
I was like you, in the cm7 by paul, I flashed normally with no downgrading....
Just do it...!!

Depends on the kernel you're using. NAa's is the best one out there. Zombie panic is at par with it. Tonnes of features with outstanding speed and stability.
But i guess you're aware of it now
I'm a complete noob when it comes to tinker my x10. I recently installed DonutHD2.2 on it, it has baseband 2.1.71 and Kernel 2.6.29-000530g5f01537 [email protected] #1....
I've heard alot about doom kernel and the others, however I want to know what's the basic purpose of a custom kernel and which one is the best for my rom. Stable wifi connection is my highest priority xD.
Please help a newbie .

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.

Yes, I am also running DoomKernel
I am using 2.6.29-modFXP-DooMKernel-v04b; could recommend it. And wifi works great (using it often, dont want 3G data plan).
As was told - depends if you are on locked or unlocked bootloader; but locked doesnt matter I have it also for to be completely save

I don't know if I have locked or unlocked bootloader. ^.^
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..

Personally I havent used Feralab ROMs, but on other ones I didnt have any problems.
You dont need to backup stock kernel, it cant be erased (only after bootloader unlock).
If you will find any problems, we or I will surely help you
Yap, on locked BL u can't erase stock kernel, u don't need to backup.

Flashing Kernel
I am a total newbie and have rooted my x10 and unlocked its bootloader. But now I want to use custom roms but do not know how to flash a custom kernel. Can you guide to a thread which can show step by step guide on flashing custom kernel???
Any help would be greatly appreciated.
I am searching all the threads since last month without any success.

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 ??????
6 Profit

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...

Hi I would like to ask whether rooting the phone is the same as unlocking bootloader. Thanks!
No, it's not.
Rooting allows you to view and edit system files.
Unlocking the bootloader allows you to install custom (non-official) kernels.
So rooting my phone and unlocking the bootloader is 2 different issue?
Or does rooting my phone actually unlocks my bootloader as well?
Rooting does not unlock bootloader.
Unlocking bootloader can help root your phone (installing a pre-rooted kernel, for example).
Is it then possible to install a custom firmware without unlocking the bootloader or will there be problems if I install a custom firmware without unlocking the bootloader.
These two custom ROMs are the only ones that can be installed without unlocking the bootloader.

OK THANKS! SHALL GO CHECK IT OUT And can I ask, does the phone by itself already have a kernel? If it has, what is the use of installing another one?
Stock ROMs have their stock kernels.
Custom kernels can add some features, such as (for example) the chance to overclock the CPU. Almost every custom ROM needs a custom kernel to work properly.

Wrong. Custom ROMs do not need custom kernel to *function or work properly*.
The custom ROMs are installed at the Read Only Memory of your phone.
For that, you need to use an installer which has to be somewhere outside the Read Only Memory. Only such location on your phone is the kernel. So a custom kernel does nothing but adds an installer outside the Read Only Memory (that is the CWM Recovery).
Now to intall a kernel, you need an installer outside of your Read Only Memory as well as the kernel. That's the PC, and the installer is Flashtool. So, flashtool is used to install custom kernels on your phone.
Note: The two ROMs which can be installed on locked bootloaders are exceptions to this rule.

Rick

If it were like you said, any custom kernel could work with any custom ROM, as long as it has a Recovery to flash the ROM. There are different custom kernels because there are different ROMs, and each custom ROM works only with one or more custom kernels, but not with everyone. If you were right, one single kernel with recovery would be usable for every custom ROM.

Yea. It would be. Infact it is.
However, ROMs like CM9, which are NOT based on the stock ROM will not be able to work on the stock kernel. It will require a kernel which has been designed specifically for CM9. On the other hand, we had seen MiniCMSandwich, which looks like CM, but is based on stock ROM. This will work on any kernel that has a custom recovery. MESA, Rage, X, Stock Exteneded and so on...
So, to put it in other words, suppose you plan to flash an HTC Phone ROM as it came in the HTC device on your Xperia Device. You plan to just change the drivers. You will need a kernel which is designed for the HTC ROM.
But, if you, on the other hand, start with the Xperia ROM and change the aspects of this ROM into the HTC ROM's, you can make the ROM work on any of MESA, X, Rage or extended.

Stock extended, yeah. Try to run MiniCMSandwich on Gingerbread stock extended kernel. Will it work? Of course not. All the kernels you named are based on stock ICS kernel, so it's simple to run ICS based ROMs on them. This doesn't mean that every kernel with recovery can make them work

Stock GB is to Stock ICS is same as Stock Xperia ICS is to Stock HTC ICS. They are different ROMs. Completely.
The ROMs have instructions according to which it behaves with the kernel. These instructions are all same for kernels that are based on stock ICS. So if you want to try any ROM that is based on stock ICS and such kernel will do.
But CM, GB, HTC ROMs and so on, are completely different.
Say you want to port an HTC ROM to Xperia ICS. You can do the following (I am taking example of the bootanimation file)
1. Simply change the bootanimation.zip file at /system/media of the stock ICS ROM.
So your ROM is based on the stock ROM itself. You just change the files, not the way the files are accessed. You do not even change the way the kernel is accessed. So any kernel based on stock ICS *with recovery* will do.
2. Change the whole Read Only Memory Partition.
This makes all the files replaced, the way HTC has made the ROM. This time you will need a kernel *again with recovery*, built to be accessed by the very specific ROM.

MiniCM7Pro will only run on the stock kernel, there was no need to unlock your bootloader, and most certainly not to install a custom kernel. Get back to stock kernel (I think there's a link provided for a kernel you can flash with flashtool) and then run MiniCM7Pro.

No, the order doesn't really matter, but your phone will only work if you pair the right kernel and the right rom together. The ROM post will state which kernel it will run on.
so for:
MiniCM7Pro - Stock Kernel
MiniCM7 - nAa-13 Gingerbread kernel
ArcMiniNxt - Just about every kernel
MiniCM9 - nAa-04 ICS kernel

Just about all roms that state they're based on CyanogenMod (CM) include App2SD by default, all you have to do it activate it in settings.
ArcMiniNxt is a Gingerbread ROM with a sony ericsson framework, so it will look and work a bit like the original firmware, but based on Gingerbread, and it will run on the stock kernel. It seems smooth and easy on battery-life.
MiniCM7 is sort of the 'default' ROM to go for if you want Android look-and-feel, it is further developed than MiniCM7Pro, but you will need the nAa-gingerbread kernel for it. It is also very smooth and fast.
Mind you, nothing is perfect, you can expect some problems with your keyboard layout and keyboard lights on all Gingerbread ROMS, but there are fixes for that if you care to search through the x10minipro development forum

i just installed MiniCM7Pro, rebooted the phone and its now stuck on that android motion logo :S is this normal?
edit: NVM it is normal ahha.. xD i now have it perfectly installed im in love with its interface. i now have to get use to it.
So, I'm a pretty average custom rom user of an x10a.
I've flashed and tweaked out with several gingerbread roms, without any issues.
Recently I found about the newer 4.1.2 roms for the x10 from late December. And I was wondering, 'cause I want to update to one of those, I understand that they're flashed in the same way 2.3 roms are. But, my xRecovery is the 3.0 gingerbread ready version. So I don't know if it will work at all after I've installed one of the Jelly Bean roms.
So I'm kindly asking anybody who knows on the forum if it will still work after I flash to 4.1.2. 'Cause I'm not certain which rom of the two I found is better for me. And I want to test them both out, but of that of course I'd need xRecovery working.
In short I'm just asking for a y/n answer on will xRecovery for the Xperia x10 work after I've installed a 4.1 custom rom, or will I have to go back to stock 2.3.3 and re-root and unlock my bootloader again?
Big thanks to anybody who replies This is the first post I made here, and probably the only one I'll never need.

copy your choice of rom, ics/jb into your sd card. install the appropriate kernel via flashtool. all ics/jb kernels includes CWM so you should have no problem installing these roms granted that you have unlocked bootloader.

It can be done, but it depends on which kernel you flash.
Some kernels only contain CWM, while others contain xRecovery and CWM.
But you can always flash a kernel that has xRecovery (Like Doomkernel of ferkernel 3.6), and thus you have xRecovery.

What you must understand is that a Rom comes with some installation scripts. CWM and xRecovery will able or not to understand those scripts.
In order to be able to flash a ICS or JB rom from xRecovery it means that the rom has to been prepared to be flashed thanks to xRecovery.
The Recovery "manager" are provided with the kernels, so there shouldn't be anything to ask about xRecovery or CWM regarding Roms,
just flash the kernel that works with your rom and you'll get the correct recovery to install the ROM from.
The only exception is that on some phone, the CM10 kernel doesn't want to go into recovery before flashing CM10 Rom (happened to me when coming from stock gb), so you have to flash CM9 kernel, install CM10 rom and reflash CM10 kernel.
The question of xRecovery and CWM is more when you try to flash some libraries after the installation of the Rom.
So regarding this question, there's no ICS or JB roms (that I know of) that have a xRecovery scripts.
