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.
Please use search function. This information is already published in this forum and there is no need of a new thread for same questions. Thanks.
I have WT19i and i have unlocked the bootloader official method. Now i flashed .58 firmware and now i wanna update to .62 but i have read somewhere that after unlocking bootloader if u update the phone gets brick.
So any solution?
If i flash .62 firmware directly then would i get root access too?
cause i have root access in .58

If you have stock kernel, just relock the bootloader. Making update directly from phone with unlocked bootloader causes brick indeed.
First relock the bootloader, then make update directly from the phone(3G or WiFi) to .62.
Relocking is written in my tutorial, check there if you need help how to do it.
If I relock bootloader, the process perform a wipe same as when I unlock via Sony Official Method ?
I want relock my bootloader, but with no wipe =D
(using stock kernel and stock .58FW)
Dont forget that wipe is best thing what you can do before upgrade to ics

I have Rage Kernel installed, so now what to do?
Or shall i flash a custom rom?
and one more thing, if i install custom rom then would i be able to upgrade to ics easily?

Your question is already answered, on the ICS stuff. Reload original firmware just to be sure prior update, always perform clean wipe when shifting ROMS so as to avoid un-pleasant experience and make most of it.
I've Sony Xperia S (SIM UNLOCK & BL UNLOCK: NO) stock ICS (LT26_6.1.A.0.452_Generic_CH_1257-3740_)
I've got a operator-blocked phone but rooted with Shazar22's old method (new method won't work). Is it possible to flash a non-stock kernel through CWM?
Thanks
no, it is not ..

Hello everybody! I'm about to buy an Xperia U, and I have a few questions about bootloader, CWM and phone models.
I used to have a SGM which didn't have bootloader, locked and unlocked stuff, so i'm kinda lost here.
1-I see that there are some tutorials to unlock bootloader. Ok, if I unlock it, will there be any differences? Is it really needed?
2- There is CWM for locked bootloaders, but if i'm gonna flash some ROM, it will have to be for locked bootloaders or I can use any ROM after having CWM?
3- CWM backups Stock ROM?
4- Any physical differences between St25a and St25i? Can I flash a St25a ROM in a St25i phone?
5- If I update Xperia U from GB to ICS via official sony software, I can unlock bootloader after updating or I need to do it while on Gingerbread? Or I'll have to unlock bootloader while on Gingerbread and then flash official ICS ROM via Flashtool?
I guess that's it, if I remember something more i'll ask.
Thanks in advance
Sorry for my english
EDIT: Wait, Titanium Backup doesn't work on locked bootloader?

1.Unlocked Bootloader is not needed unless you are to install custom roms,kernels and stuff.It doesn't make difference in performance.
2.NO,you can only use roms which are for locked bootloaders.
3.It backups all the data of stock rom.if you want to revert to stock rom again you will have to flash it.
4.Don't know about physical diff,and also not sure about flashing st25a on st25i.it may harm your handset.but only difference is in baseband.
5.you can unlock whenever you want.But I guess once you unlock bootloader you can't use pcc or sus.(pc companion and sony update service) for updating your phone.But again,you can relock your bootloader anytime.
If you are going to flash it via flashtool you will need to unlock the bootloader first.
Told you all I know.if I helped anyhow hit thanks.
I am also a noob.so,if I am wrong anyone can correct me.

1. Leave it locked, safer until you get used to messing around with the device.
2. You can only use Rom's for locked bl.
3. Yes, with all your apps and data.
4. I have st25a on my st25i, no hardware difference.
5. Unlock bootloader on 2.3 or 4.1, you can only root with ICS afaik.
Also be aware that most sim locked Xperias cannot unlock bootloader ever, get yourself a sim free device if want unlocked bl.

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!
