I am proud owner of SE xperia arc and updated to 2.3.4. with latest 4.0.2.A.0.42 build. I have few queries regarding unlocking bootloader and rooting the device.
1) I understand what is unloking bootloader, by instruction given by SE officials. I want to confirm that will i be still able to update with SE Companion for any new release they offer after going for unlock?
2) I have seen many thread confirming rooting of arc with custom ROM. Is there any specific thread/link where i can find SE custom ROM with same features offered by original ROM?
3) Will the features differ in custom ROM from original one?
The reason i want do rooting is just want to get rid of useless apps installed by SE itself and to get more RAM free for my other frequent apps.
I do understand these things are answered here and there by i need a consolidated one.

and many more if you can spend some time in searching.
1. No, you will not be able to recive new updates from sony ericsson (un less you relock your bootloader and flash it to stock ROM)
2. The best one is cyanogenMOD

More CUSTOM ROMS

3. CyanogenMOD and every other customROM have more features than original (some are kicked out, some are added to it, by the will of maker)
P.S.
For rooting you dosent need to UNLOCK BOOTLOADER, you just need to ROOT it..
Unlocking bootloader remove your warranty..dont unlock it if you dont wanna custom ROM on your phone...

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.
This is follow in from thread = [Q] How to Root Xperia Arc LT15a 2.3.4 Build: 4.0.2.A.0.62
[ I cannot edit/post to my thead "To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages"? ]
I don't know why this thread is dead, it seems to do what I want and install official ICS and root the phone except it states after install "Its your wish if you want to stay on it but i suggest you to repair your phone software using SUS. It will reinstall the original ICS software in your mobile"
which suggests requirement, not mentioned, to have ICS installed and not the version I have installed Gingerbread v62 (4.0.2.a.0.62 2.3.4). Can anyone help?
-----------------------2nd post here as cannot post reply ------------------
Sorry I was not clear, I have Xperia Arc LT15a 2.3.4 build 4.0.2.A.0.62 installed with an unlocked boot loader and want a site that will give me the steps to :
1) install the latest official ICS
2) root the phone
I was following steps to do this on one site that required unlocking the bootloader, which I've done, but could not continue with the remaining steps as the links were a problem.

Hello everyone,
My question is i subject - I have Japanese Xperia Acro IS11S, with Android 4.0.1.B.0.117
Wonder how can I root it? I rooted it before, while on 2.3.4, using SuperOneClick software (found on XDA, too). Will it work with 4.0.1 as well?..
Just do not want anything go wrong so.. maybe someone rooted same phone already and might share some experience, or any advice will be appreciated
Thanks!!!
Hi all, I have a arc s with locked bootloader but sim unlocked (by IMEI code) and I can't unlock it (unless I pay for it, and I don't want to pay...)
I want to know if I can flash another rom without unlock bootloader and if the answer is yes, what roms can I flash and how.. Because im new on sony ericsson devices.
Im on last version for arc s(4.0.4) without root access.
I new to know:
- how I can flash a rom with locked bootloader
- What roms are the best to flash ( if possible, 4.1.2 or 4.2 versions... )
- how to do all this things...
Thanks a lot !!
