Regarding Kernal Flashing - Upgrading, Modifying and Unlocking

Hi,
I am a noob in android stuff, so was going through all this forum for a while (around 1 month).
I had unlocked my bootloader for sony xperia neo V.
People say of flashing kernal before you put ROM into Device
is it neccessary ??
I Right i have got cm-9.1.0-haida and wish to use it on my Neo..
and my current build for phone is
2.6.32.9-perf kernal &&
4.1.B.0.587
should a kernal flash be required ??
shall i put cm9.1 through cWM recovery mode ?? via update

[Q] how to root my hongkong-version 4.1.B.0.431 LT15i?

i've been looking around here and found some posts about rooting the 4.0.4 of LT15i.
for my locked bootloader LT15i, i might flash the 4.0.3 .FTF(4.1.A.0.562) ,then use the one-click root ,then flash back to the 4.0.4 .FTF(4.1.B.0.431)
should i use the right 4.0.3 .ftf and 4.0.4.ftf (use my HK version .ftf)?
but i can't find any hk version 4.0.3/4.0.4 ftf in the forums.
if i flash with the global version ftf ,is it harmful to my LT15i?
BTW, in my software info, it says: file system version: WORLD-1-8_4.1.B.0.431
phone software version: 1241-4324_4.1.B.0.431
Just flash stock 4.0.3 kernel, root and flash stock 4.0.4 kernel. This way you get to keep your HK customisations.
(To flash the kernel alone, exclude all other options in Flashtool).
And flashing different .ftf's won't harm your phone. You will just lose some of the customisations i.e. some region specific apps. In most cases, it's just bloatware.

Thanks very much !
And could you give me a link of stock 4.0.3 kernel and stock 4.0.4 kernel (what does 'stock' mean here?)
i just downloaded a 431 general-global ftf from the post and it's 199MB, it may not be the 'kernel' ,is it?
You've downloaded the entire ROM, hence the big file.
Download the LT18i .562 ftf from the same post as well. This gives you 4.0.3.
Put both the .ftfs in the firmwares folder of Flashtool. Now when you choose to flash, you should be able to see both the firmwares listed. Choose the .562 and EXCLUDE everything except the kernel (in the options on the right hand side). This way, you're flashing just the kernel and nothing else. Root it and then do the same thing with the .431 kernel.
Stock means the unmodified firmware you got from Sony (Ericsson).
NB: There's a 4.0.3 kernel alone somewhere in the forum. If you don't want to download the whole 4.0.3 ftf, you would need to search for this.

You need ICS firmware aswell, ICS kernels work only on ICS firmware, GB kernels work only on GB firmware.

Don't mix Stock ICS Kernel 4.1.A.0.562(ICS 4.0.3) with 4.1.B.0.431 firmware i did the same mistake and i had the sony Logo appearing repeatly. to make your fone boot correctly just flash any kernel based on 4.1.B.0.431 (ICS4.0.4) with any ROM (stock or custom)based also on 4.1.B.0.431 only
Man, read a little bit the threads at Android Development.
Some roms, you don´t need to unlock your bootloader to install.
About battery, if you have good signal strengh, you only need to root your phone and remove bloatware (sony apps) and your battery will start to last. I use stock ICS 4.0.4 rom with Stock kernel, stock baseband, and my battery usually lasts from 24 to 48 hours.
I use a program called 'No Cpu Frills' and set my cpu to the minimum of 133mhz and to the maximum of 1024mhz, even my phone being an Arc S.
The rom you´re going to use depends more on what you want from your phone. Some roms are designed for games, others for business, others just for ego (lol) and etc...
We have many good Roms for Xperia Arc and Arc S here. Take some days and test them... only you can say for sure what is best for you.
I, for example, before getting back to stock, used a lot the IceBean 4.2 (It´s xperia S´ rom with modifications. Very sexy, indeed.)
Good luck on your quest... =)

If you have unlocked your boot loader you cant install OTA updates or any official Sony updates. To get official Sony update from PC Companion or Sony Update service or Over the air you need locked boot loader. To install official Sony firmware on a device with unlocked bootloader you need to have a tool called flashtool installed on your PC.

NXT ROM + Doomlord Kernel question

Hello! This is my first thread
I have this following problem: I've got the bootloader unlocked and the NXT Rom 1.2 but now, i'd like to flash the Doomlord kernel v14.
The question is:The build of my Xperia Play R800i is 6.0.A.3.73 ... can I flash the kernel with this firmware?
Becouse in the requirements of Doomlord post there is:
"[ requirements ]"
stock SE 4.0.2.A.0.42/.58/.62 FW
I'm sorry if my English is not very good.
yes you need to have one of these build no. or you may try other doomkelnels for lower build no.

So,what I have to do now?
Must I flash the 4.0.2.A.0.42/.58/.62 FW? Or I can stay with the 6.0.A.3.73 and flash the doomkernel(v14) with this current firmware?
i mean if you want doomkernel(14) then flash .42 etc if you dont want to change frmw then just flash doomkernel provided for lower frmw but you will loose some features which were made available in v 14. v 14 doomkernel is latest for gb whereas for for lower frmw doomkernel is outdated
Ok thank you very much.
But I've got the last noob question: So,can I flash the 42.(or 58/62) if I have the Nxt Rom that changed my fw to 6.0.A.3.73 ?
Thx again and sorry.
well i dont think nxt rom changed your build no. to lower because it requires .58 so you initially had that lower version.
now use flashtool to flash stock .42 or .58 that you want. and then flash other things i.e kernel and nxt rom again.
and one question for you did nxt really changed your frm ver to 3.73? bcoz i flash .58 based rom (i.e gin2jelly) on .42 and now my build no. is .58
and press thanks button instead of manually saying it
and I recommend to flash 4.0.2.A.0.58 Enhanced FW only because of 420mb userdata partition and simple root.
Well,this is what I did:
1-Unlock the Bootloader.
2-Flash firmware 4.0.2.A.0.58 Enhanced via Flashtool.
3-Install XPERIA NXT v1.2 by Kris Dee.
And after this..if I go to settings my build number is 6.0.3.73. But I thought it was normal becouse on his site (http://forum.xda-developers.com/showthread.php?t=1649368) he says that this rom is .73 based.
So now I must reflash the 58 Enchanced firmware.After this flash the Doomlord kernel and finally the NXT Rom, right?
Ok I did it by myself...and now I have doomlord kernel with Dixperia 2 Thx.
Well, you didnt needed to unlock bloader for NXT rom, but it will have advantages Have fun!

You can do that but then your baseband will be stick to 4.4.2 ver and not optimized for 4.4.4 sometimes will lead to compatibility problem on 3G/4G or wifi connection. Baseband sometimes can even to affect the camera performance though this is rarely to happen.
You can try it first and see if any problem found on radio part. If you want to do a real flash start from the scratch then probably a lots of job you will need to do.
http://forum.xda-developers.com/showpost.php?p=54297393&postcount=5
You can follow my detailed guide but actually you don't need to follow all steps, you just need to ask flashtool to flash the baseband part.
Thx theendHK,

If you ask questions please be exact and complete with your first message
If you what to install 4.4.4 custom ROMs you need Jelly Bean (JB) at first!
You are still on Gingerbread (Baseband XXLL2 is GB)
1) Flash JB FW accoring to your Phone (http://samsung-updates.com/device/?id=GT-I8160 - I8160XXNB1 or I8160XXNF2)
2) Flash TEMP CWM via Stock Recovery (http://forum.xda-developers.com/showthread.php?t=2141395)
3) Flash 4.4.4 custom ROM you like via temp CWM
An seperate rooting is not needed because almost any Custom ROM has Root integrated.
