[ROOT][LOCKED][FTF]Neo/Neo V OFFICIAL 4.0.4 ICS

1. First download 4.0.3 kernel. (Neo V officially but will work on Neo)
2. Open flashtool 7.0 or newer version and flash just the kernel: untick wipe data/cache and tick exclude system/baseband and no final verification check.
3. Root with DooMLoRD's one click method shown here.
4. Optional: install CWM.
5. Now reflash 4.0.4 kernel using flashtool like shown above.
If you somehow do not have 4.0.4 firmware or if you are not on ICS but you want to update to, follow this guide from where you can download 4.0.3 and 4.0.4 ftf.
is it also applicable on Neo MT15i ? ? ?

this thread is for 4.0.4 android version but you may try the same steps on your device just with flashing .42 kernel, rooting with zergrush v4 method NOT this one and then reflashing .62 just be sure that nothing bad can happen to your phone if you flash just the kernel

I'm not sure what you want to say. If you are asking about updating to ICS, rooting the phone is optional. Here is how you can update to ICS.
I must have ICS 4.0.4, for I can from 2.3.4.¿?
Sorry muy bad bad bad ... english.

Is The Kernel Updated To 3.0.x in ICS 4.0.4
Works!!!
I confirm that this works.
From 4.0.4 (4.1.B.0.431) then flashed the kernel (4.1.A.0.562) and followed the doomlords guide and back to (4.1.B.0.431).
Phone (Xperia NEO) rooted =) locked BL thanks man.
Ok I'm a noob. Where the hell is the thank button
ok i need to post first to see the thank button.
Works great.
I've bootlooped my phone several times before, with the other tuts, but this works great.
Works here, locked bootloader.

lol and how do you expect to have 4.0.4 if you don't want to download the whole rom?
you wanted to ask for a 4.0.3 kernel?
if yes, get it from here: http://forum.xda-developers.com/showpost.php?p=26798415&postcount=141
I meant,i am already on ics 4.0.4.
to root it,i need to flash first the kernel of 4.0.3 and then 4.0.4.
so,download link for 4.0.4 kernel?

Download Odin (can be found in this forum)
Download your stock firmware 2.3.6 (I dont know about the CHN_CHN Version)
Put your phone into Download Mode. (Power Off, Hold volume down+home+power button)
Run Odin
Choose PDA file which is your stock firmware.
Flash

Use search.. You will find lots of topics,, Anyways, following link will guide you :
http://forum.xda-developers.com/showthread.php?t=1110160
IMPORTANT : While choosing model from the dropdown on Checkfusdownloader, choose "GT-I9100G"... Do not choose "GT-I9100".
相信你是个中国人,要不然应该不能买到中国版的9100G。
用Odin刷5文件包吧…………

I tried this before when I first flashed to CM9, I get bootloops. Since then, I forever stick to ICS and never trying to convert back to GB although I wish to do so. I dare not and i'm lazy to deal with the bootloops.. I not sure why I get bootloops btw, some other ppl faced that as well. So I hope this brother able to convert back to GB successfully. Good luck.
To convert back to GB you have to flash an old GB bootloader for some reason after flashing the stock ROM. After that do a full wipe, everything else ended up in a bootloop for me.
Fingers crossed .

So end up you success? Would you mind to share the old GB bootloader? Not the stock rom. Is the particular bootloader. Thanks!!

I can flash GB stock GDZKL3 after flashing this bootloader right? bootloader should flash before flashing rom, or after flashing the rom? Thanks.
I tried both options. Try flashing the bootloader at first but don't forget to uncheck "Auto-Reboot" in odin. After that you should be able to flash the stock GB ROM. Do you have a jig just in case of any problems? I remember I used my jig, but don't really know why.
