I bought an xperia arc s two days ago..and I want to unlock bootloader/root/install CWM and costume roms..but some friends advised me not to do so and keep on stock status..because thsey claim that I may not be able to update the phone to the supposedly so near almost on the door ICS of android..is it true?and if I did the unlcok bootloader and rooted..won't I be able to revert back to stock and update to the ICS when it comes?what do u think guys..?thx in advance

If u unlock bootloader, u cant update through pc companion. However, u can always relock back the bootloader, allowing you to update using pc companion.
However, in my opinion, having an unlocked bootloader doesnt bring any downside (except losing drm) coz u can still flash ICS using flashtool or flash it as .zip coz the devs at our forum will surely modify it or something...
However,its all up to you

I think it doesnt matter which rom r u on to relock it as long as ur on stock rom. But I recommend using fw .42 to relock cause that was the firmware I usually use to relock.
Im right now using xperia s beta rom 5, doomkernel v19...

I think you can relock any baseband if you unlock the bootloader with the official se method. If you unlock it with a testpoint methode you cant relock it.

I tried to OTA update my unlocked Acro S to 6.1.A.2.50

without knowing my phone's bootloader was unlocked by the shop in the 1st place!!!
it's currently 6.1.A.2.45 Root Status: Unlocked Bootloader = Yes...
after downloading the update, the phone shut down automatically while installing the update, and a brief recovery screen appear on the restart, the phone would still start normally but there's a notification telling me the update could not be installed
I repeated this a few times then only I realize my phone was unlocked and OTA shouldn't be done on an unlocked phone :crying:
had it done any damage? I can't tell....
please help, thank you guys very much in advance........

the shop must have unlocked and rooted it for me I guess, not sure about their warranty policy
has Sony implemented a safety measure to prevent unlocked phone from installing the udpate? people used to get into trouble for OTA-updating unlocked phone right?
TQVM..

you have purchase a used phone no shop or company will root android device or unlock bootloader,this things are void your warranty

If u have an unlocked bootloader on ur device, u will experience FOTA brick while you try update OTA, I heard PCC stops working as well but SUS works for some. But you always have access to flashtool for flashing new fw.

Have you tried repairing your phone in PC vompanion?
Sent from my Xperia Arc S using xda premium

pc companion cant repair it as it needs me to go to notification via phone which is impossible since it just bootloops from sony to xepria logo.

Getting your Phone back to a factory state DOES NOT require you to be rooted or have an unlocked bootloader, the thing that's lacking here is reading, and persistence. You need to figure out getting PC Companion, SEUS, or the Flashtool (Official and un-Official) to work, so as you know what to do, it's over to you to do it, and if it's not working then you're obviously doing something wrong.

i personally prefer flashtool. simple to use and doesnt require root or unlocked bootloader if you're flashing stock ftf.

Can't unlock boot loader or flash stock

Hi there,
Has anyone got a way out of this.....
I have a rooted C1905 that I have been playing around with. I want to try CM11 but boot loader unlock fails with a "FAILED (unknown status code)" report after I send my unlock code. I then thought I'd flash back to stock using S.U.S. but that fails too saying that I have a customized rom... which I don't!!! I seem to be stuck! is there anyway to force a stock flash?
Cheers

Have you checked if your bootloader can be unlocked? Go to the dialer, type *#*#7378423#*#* then go to Service info => Configuration. In rooting status, it should say "Bootloader unlock allowed: yes", otherwise it won't work. About your flashing problem, try connecting the phone directly in flash mode before opening SUS, by turning off your phone, holding Volume Down and plugging USB cable or by flashing a FTF file through Flash Tool...

It happened to me also ,check your IMEI CODE,you need to send first 14 digits of your IMEI,

Flashed an FTF of the latest but still can't unlock the bootloader. still get "unknown Error" and it wipes my apps.
Also can't use "repair my phone" on PCC as it says I have a Customised Rom, could this be due to me trying tools like flashgordon and debloat/deoxing flashing or routing? if so how can I get back to a stock state for a UK XM so I can start again?

Nope, but try this anyway.
1. Disconnect your phone and turn it off but keep the cable attached
2. Open PCC and go to Update
3. When it says no device found click the blue repair link
4. Choose Xperia M when asked to
5. Follow the instructions
I have a locked bootloader and modified ROM and it works flawlessly. Keep us updated

Hi there,
Thanks for the help, unfortunately it doesn't work! PCC recognises my phone ok so I carried on to the "repair my phone" tab.
and this is what I get after it's downloaded the firmware and tries to flash it...
