Can I flash a stock kernel without unlock the bootloader? I want to install the .100 in my Xperia U but, to root says that I need to flash B.10 kernel and then, root or something. How can I do that? And install CWM in .100? Please, help me. I have a locked bootloader because says "bootloader unlock allowed: No" Thanks

You don't need unlocked bootload to flash stock kernels. You need unlocked bootloader if you want to install custom kernel and roms as muiu, cm10, cm9.1 etc.
This is the procedure you have to follow:
1)Download and flash via flashtool b.100 .
2)After that go here and download b.10 kernel: http://forum.xda-developers.com/showthread.php?p=40513111
3)Power on the phone and root it using this tool: http://forum.xda-developers.com/showthread.php?t=1886460
4)After rooting, install cwm using this one: http://forum.xda-developers.com/showthread.php?t=1948455&highlight=cwm
5)After that, from the ftf file of the .100 you previously downloaded, using winrar, extract the file named kernel.sin and flash it via flashtool.
6)Done!

my device ia neo v (bootloader unlocked) and I rooted it recently using flashtools with downgrading to .42 .now I want to update it to .62 but I saw in some posts that I must do that with ota..but everytime it says couldn't update the software..so I want to install it with zip package with cwm menu..can anyone give me a zip package to install from my sd card?
First relock your bootloader,upgrade to .62 via Pc Company,then unlock bl again and flash RootXperia via CWM,and that's it,you'll have .62 rooted.

ohh...unlocking and relocking bl is really hard as the official sonymobile site tells..
It's not hard at all,it takes only 5 minutes.

Hi guys...
Last week my xperia mini ST15i just updated to 4.1.B.0.587
I am going to root, unlock bootloader and install custom rom on my phone, but looks like there is no clear instruction on how to root it...
I did found some instruction though, but i am not sure which is good :
1) http://talk.sonymobile.com/thread/41119
2) http://forum.xda-developers.com/showthread.php?t=1568792 (Should I follow the method for 4.1.B.0.431 ?)
3) http://forum.xda-developers.com/showthread.php?t=1923409
Which method i should follow?
And lastly, should I unlock the bootloader before root or after rooting?
Many thanks...
Look in my signature there's how to unlock bootloader.
You needn't root it before, but if I were you I would downgrade to gingerbread before unlocking bootloader, after that flash a prerooted kernel like rage kernel for gingerbread and your device will automaticly be rooted

Thanks for your reply... :good:
What the different if I root it straight from ICS?
Those prerooted kernel comes with CWM recovery right?

No there's no difference, do it on the software version you want.
Yes these prerooted kernels will root your device automaticly and cwm is built in the kernel

1. No difference. You'll just have ics firmware . You can just unlock your bootloader the official way while in ics and just like that flash a custom prerooted ics kernel .
2. And yes all custom kernels for our device has cwm .
No need to downgrade to ginger bread just for gaining root access if you are going to unlock bootloader!
hit thanks if I've helped!

I would use this method, but you need an .ftf of .587 for your device, if you have one, do it like explained there.
The kernel trick method is okay, too
I suggest you unlock your bootloader first by this
http://forum.xda-developers.com/showthread.php?t=1560613
(it directly unlocks bootloader without writing any commands)
And then install a prerooted kernel via the above mentioned toolkit...
Your will be rooted and then just flash the custom ROM :thumbup:
And the best part... You don't need to downgrade to GB

1. Yes u can, with GB ftf file.
2. If u think on ROMs like CyanogenMod ROM answer is no, u must first unlock ur BL.
1. Of course u can, just download the file and flash it with flashtool
2. Some custom rom need unlock bootloaders to be installed, but another rom no need that.
I think if u want to install more custom rom, mod, root and etc, unlock bl is the best way

Guys, thank you very much. I succesfully downgraded to GB official stock ROM.
Now my last but very important question is - i dont like GB and i still dont like ICS (i downgraded only because of better battery life in GB), but i want to test some custom ROM (like AOKP rom posted in Sola section).
As much as i red i can not flash this ROM without unlocking the bootloader and installing CWM on my phone, is that right?
Actually the question i wanted to ask was - if i unlock bootloader can i flash custom rom with Flash Tool or i can flash only with CWM (which i dont know but i dont want to use)?

Hi,
I recently tried to root .62 LWW stock rom.
My unsuccessful attempts are recorded here:
http://forum.xda-developers.com/showthread.php?t=2068238
Again today i tried to do it 2 times. Once with Flashtools and other time with SEUS (though it says i have the latest version on .58!).
I have unlocked BL so doing OTA on .58 rooted version = stops my device from turning on.
So i am just requesting whether someone could upload a rooted .62 stock rom for LWW version? IAlso i have tried rooting on my own using Knight45's article but it failed to boot :/
So now my only option is to get a .62 rooted rom and tweak it slowly on my own
It would be much appreciated for your support in this = )
Thank you
Download A Stock ROM (Check Stickies Thread) then Flash a Custom Kernel (You Had Unlocked your bootloader right? ) so you can get Root

Hi,
Little confused as this hasn't been mentioned before.
Are you saying, for me to get root on .62, all i have to do is:
Flash a stockof .62 rom to my LWW
Flash a custom Kernel i.e. rage kernal 3.0 or x-kernal?
and i shall have root?
And also, yes i have unlocked bootloader.
Custom kernal i was looking to use (will most likely use rage kernal):

Yep, Just Flash a Custom Kernel if you have Unlocked Bootloader and you will get root
1) I had xperia U firmware 6.1.1.B.1.10 .
2) I rooted my my xperia U with flashtool.
http://forum.xda-developers.com/show....php?t=1933985
It was rooted perfectly.
3 ) Later on, I used flashtool to upgrade flash my phone to 6.1.1.B.1.54 firmware
using this --

But, now when I am opening Titanium Backup or other application. I see the message no root access found!
I saw in some thread that adding some files helped restore root access...
Please advise...
You lose root when you flash stock ftf.

Re-root if you have your bootloader locked... or use a kernel if unlocked...
When you flashed new firmware,the whole system folder was replaced with new one.It did not have su binary needed for superuser to run.So you lost root access.
Just flash 6.1.1.b.1.10 kernel,root with bin4ry or flashtool and then flash back 6.1.1.b.1.54 kernel.You will be rooted again.
Kernal vs Firmware confusion...

1)But just use B.1.10 kernal FTF(5Mb) instead of full firmware first
2) then root ..
3) Then again use flashtool and do it for B.1.54??
Any step by step link please if I am wrong ?
