Do i need to unlock my bootloader?

---

Hi,
I've rooted my phone (Sony Ericssion Live With Walkman-WT19i) and right now running stock ICS ROM from sony (build: 4.1.B.0.431). Even Clockworld Mod is installed. I want to install custom rom from cyanogenmod(or any other custom rom).
My question is : Do i really need to unlock my bootloader,coz as I know rooting may void the warranty but unlocking the bootloader will surely void it.
Please tell me the detailed process of installing custom rom step by step (right after the successful rooting and installing CWM process). I woould be thankful if u include both the process(with and without unlocking bootloader,if any).
Thank You Very Much In Advance.
Could You please mail me the steps even to my persoanl mail id sauravsagar@gmail.com

You can't install CM with locked bootloader it requires different kernel.

Yes you need to, for CM!

Yes, most custom ROMs need the bootloader to be unlocked(including CyanogenMod). There are two methods to unlock your bootloader - the test point method and the official method. If you're concerned with your warranty(which may already have been voided), use the Test point method described in the FAQ by Someguyfromhell.

And what ^ said.

Glad it worked for you! Not to be a thanks-whore, but it's just a click away if I really helped ya!
Cheers!

Might be a foolish question but I flashed some custom firmware on my Samsung Star (not Android) back in the days and only had the English language available instead of the Dutch I wanted.

If I root and install the ROM will everything also be available in English only or will I still be able to use Dutch. Will I lose something?

Another question: If I upgrade to ICS official by Sony trough Sony Bridge on my Mac and ICS is installed on my phone, will I lose data and the root and ROM?

Thanks in advance

That depends on whether the new ROM you're flashing contains a Dutch language pack. Rooting per se will not modify your data or your language. Also note that flashing can erase your internal memory data.(I have no experience with the Star, however I had a Nokia 3500c. Using the official Nokia app, I upgraded my firmware without any data loss. If you will be using the official Samsung app, you should be safe). That said, make it a point to backup your SMSes, contacts, calendars, notes etc.

Another question: If I upgrade to ICS official by Sony trough Sony Bridge on my Mac and ICS is installed on my phone, will I lose data and the root and ROM?

Will I lose root? Yes, you will most likely lose existing root permissions if you already are rooted.
Will I lose data? Unlikely, using Sony Bridge.
Will I lose ROM? Of course, that's the reason you're upgrading to ICS in the first place, isn't it?


Have a look at the following resources and any other places you'll stumble across.
