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...!!

Thank you, it worked very well! Installed the last kernel and rom by nAa and the phone is way faster than before. I bet my brother is more happy with his phone now!

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 everyone!
I'm tired using custom roms for their instability and fc's everywhere for over a year I didnt found Rom that works perfect all the time with many apps installed so I just want to my phone work, dont want to flash new system every month again.
I was running stock with deleted apps, Set Cpu (tnx to gregbradley (edit: that was neoxx3m very good advidce, sorry my bad) and z-kernel for about 4 months and I was happy, that was one and only Rom that i've used so long. Yes it wasnt so fast but it was very stable and everything works so nice not even one fc. (kindda wierd couse ive installed z-kerner on my Unlocked BL x10 and now I can't and dont wanna to play and relock)
So i wanna repair my phone and get back to stock, root it, delete all uneeded apps and flash the most stable kernel so will it be failsafe from doom right?
And the question is will my plan work? I know that phone will not be so fast but will everything work and this is all I need or maybe someone has better idea?
Also have some questions about the newest fw for this Doom UB kernel. Where do i get this newest se fw?
Any help will be very appriciated.
Restore the phone back to stock using SEUS. That should do the trick

It will work because when u repair ur phone via PCC u get latest firmware (2.3.3/3.x.x.x.x.x), but my advice is to try relock BL and use zKernel, i did that yesterday and i'm happy again!

I told you that dont wanna play with bootloader no more, maybe for some time i would like to try some kernel or rom (if im not happy for using stock and doom) and will have to unlock again so im patience (tring to) and will not to this for a while.
Anyway strange is that i flash zKernel even if i had unlocked Bootloader and it work fine but when i tried to do this again ( didnt know that this kernel is fo Locked only) it didnt work
Hey noob here.
Lots of.time I.see ppl saying this rom and that rom ....and lots of time I see ppl saying trip kernel or some feral kernel or something ...what's the difference?

hi
i myself googled it (kernel) that is and what i found was something like this
the kernel itself is what controls all the processes, inputs (hardware and software inputs), controles the fysic and virtual memory etc etc.
and the rom itself (this is with out goggling could be wrong) is the software like compared to your pc it would be windows, linux, etc
hope ths helped had to translate so hope you understand!
Thanx ! ! But I still don't understand .... I mean can v be on the stock rom n hav a different kernel? Or can v hav a different rom on the stock kernel?
Sent from my X10i using xda premium
im pretty new to this myself and i've noticed there's so many different choices of roms and kernels out there so what i can tell you are the things i read and and have done/noticed so far.
first of yes i believe you can stay on stock and use another kernel (i actually went with CM7 Zmod first then changed kernels)
second ive seen most roms giving a link to a custom kernel aswell
custom kernel pros are somewhat explained in the following:
* i remember reading that the stock kernel kept on going even while its not needed
*so i installed the doomkernel V6 (CAUTION theres a difference between kernels for locked/unlocked bootloaders)
wich allowed me to set the cpu as i pleased (by another application wich i saw people using in videos etc. ''no frills CPU control'')
i did this before unlocking the bootloader and i noticed the difference in battery consumption aswell
theres so many different options in how to set the kernel that youre better of wiki'ing em . thats what i did and helped alot in understanding what it does.
sorry for all the info you didnt ask for but it might be usefull for later on ??
Yea definitely damn useful!!!!! So frm ur point, should I.change my kernel? Cuz I don't want to flash custom rom. Camera doesn't.work.best. and games don't seem to work properly on.this present stock.kernel of Sony ( srsly PES worked better on 2.1 !)

Oh and I also want to.overclock my device xD
Sent from my X10i using xda premium
im actually overclocking aswel but in moderation i suppose
theres one higher in Mhz wich i dont use because of the following.
1 im learning
2 scared
mainly because i saw this line
v06 (only for EXPERIENCED TESTERS) [OVERCLOCKED VERSION] {DEVICE MAY NOT BOOT} ( min/max: 128Mhz/1228Mhz )
and as youl see its not that different in Mhz as this one
v06-1113 [medium OVERCLOCK VERSION] ( min/max: 128Mhz/1113Mhz )
so its all out there but im pretty carefull on reading up first and then trying
ive pretty much got it all working on the first try
* CM7 Zmod
* unlocking the bootloader (meaning instead of loading stock kernel first, cancelling this, rebooting custom kernel it just goes straight to the last step (faster!))
*doomkernels V6 unlocked bootloader kernel
So I should unlock my bootloader n then change my kernel to.which ever u r on ( while being on stock 2.3.3 rom) n then overclock it ...logically n technically is what I'm saying is right?
Sent from my X10i using xda premium
while i was looking for this i also found that he submitted kernels for stock roms wich i didnt use so im not sure why tbh :s
i believe that the CM7 Zmod isnt an actual ''rom'' aswell but a port (whatever that means )
so that means im using the stock rom with this ''mod'' and the V6 kernel non stock rom and evrythings bin working fine for about 2 weeks now
rom = like windows xp software
kernell = using software to mod the motherboard so its compatible with the rom
So can I stay on stock rom n change my kernel?
Sent from my X10i using xda premium
whatever you use should be you're choice i suppose but what i did was .
get the kernel for the LOCKED bootloader first theres plenty of em out there.
dont forget the app youl need to control the cpu itself
ive seen posts of people refusing to unlock there bootloader mainly because you can mess up and brick (destroy) your phone
so whatever you do . dont unlock it untill some more exp. people explain what its all about.
im not sure so dont believe me on the following.
i believe it was something about unlocking it and doing a full wipe or such means youl do A FULL WIPE bye bye xrecovery and an endless bootloop
because xrecovery isnt or wasnt (fixed or not) build in the custom kernel
so untill then be safe theres plenty of roms/kernels etc to try with a locked bootloader so you'll wait 15 sec longer for the extra booting thats required
only reason i did it was to go straight to the custom kernel and to multi boot roms meaning i can try out other roms and still keep the one most stable for daily use.
What is perhaps the most prominent use for unlocking the booloader is that u can have your recovery built-in at kernel level (as is the case for pretty much every ulbl kernel), meaning u will always have recovery on ur phone
Sent from my Xperia X10 using XDA
That's it? For just having recovery u need to unlock bootloader?
Sent from my X10i using xda premium
no no hes saying ''at kernel lvl'' you even got recovery with your locked bootloader if im not mistaken ? (think you told me in some post)
so if i understand it it means even if doing full wipes etc youl always have xrecovery cause its build in on kernel lvl (so build in your custom kernel)
No I mean that if u flash to stock or anything usually u would break recovery but with ulbl it ALWAYS there. There are other reasons too (like extra schedulers and governor's for CPU)

Hey, I'm interested in this so I'm gonna jump in on the conversation.
I've read that with an unlocked bootloader, the recovery is built in at the kernel level, and from my limited knowledge I thought the kernel resides in the boot partition. Why wouldn't the recovery be in the recovery partition? Is their a recovery partition?
When I did a nandroid backup, I notice that it only backed up the sys, data and dalvik. Maybe theres no boot or recovery partition.... I'll eventually learn all the answers I need, I figured this was a good thread to ask some of these questions.

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
