[Q] Is unlocking necessary? - Xperia Arc Q&A, Help & Troubleshooting

I'm quite new to meddling around with phones, but after reading around, it seems that to get the most out of your phone, or for more advanced options, you must root it or unlock the bootloader.
So I have a few questions....
If when I go to configuration information it says "Rooting Status: Bootloader unlock allowed: No" does that mean I can't root my phone, or install custom ROMs?
What does unlocking the bootloader really get me?
Will it void my 1 year warranty? Or is there a way I can still send it in if anything was to go wrong? Maybe re-lock the bootloader?
Do I need to unlock my phone to flash a kernal?
Thank you!

First, I'd recommend to you to read this thread.

You can flash custom ROMs/kernels, etc.

You can relock your bootloader, but only to receive OTA's or to use PCC or SEUS.
But you'll void your warranty!

No, my bootloader is locked, a flash file that I blocked again.
I made the lock to try to upgrade to the ICS but had not tried to unlock then upgrade again and is giving error.

Anybodyyy?
dude whether your phone is locked or unlock..it doesnt matter if u flash a ftf file in flashtool..it wont even take much time this way..so just download the latest 4.0.4 ftf and flash it

Will I lose the maintenance if i unlock my device

will i?
Do you mean updates from your carrier? I'm not sure the answer, but since it looks like you have an international Ion you should be able to unlock the bootloader, so you would just have to flash the upgrades manually if you can't receive maintenance OTA
If I'm wrong someone please speak up
If you unlock the BL then you will be unable to do OTA updates or updates through PC Companion unless you relock the bootloader first. As far as warranty goes thats up to Sony if they will still provide warranty repair after the BL is unlocked. Look at the Sony Bootloader unlock page for info. http://unlockbootloader.sonymobile.com/

No they will always know you unlocked it via the official sony way because you have to provide your IMEI number to get the unlock code.

Hello Guys,
Today i was about to unlock my bootloader using SE Bootloader Unlocking v1.6(http://forum.xda-developers.com/showthread.php?t=1560613) but before doing so i used s1tool to identify my device.Here is the screenshot. Check my S1_EROM version it starts with "r" not "R".so it's alreay unlocked? How do i know(check) my mobile has bootloader unlocked?
I bought this mobile almost a year ago and it was brand new from stock.So not sure it's already have bootloader unlocked since i haven't unlocked the bootloader yet.I just want to know what's happening.Sorry if this question has already been asked as i am kin of noob(but have rooted and flashed ROMs using flashtool and CWM) and want to know what's the bootloader status.If anyone know how to check bootloader unlock staus it would be very kind to share as i am gonna unlock my bootloader and need to recheck if it's unlocked properly so that it won't brick my phone.

Try flashing a kernel is the obvious and simplest answer.

So if my bootloader is locked it won't let me flash custom kernel like(boot.img of cynogenmod) or it will brick my phone? You link doesn't explain anything on how to check bootloader unlock status."bootloader unlock allowed:yes" will be for those devices whose bootloader can be unlocked but it doesn't tell you if bootloader is unlocked or locked.
I simply want to unlock my bootloader.Then flash cynogenmod.I want to make sure bootloader is unlocked properly before flashing cynogenmod kernel.If flashing boot.img on bootloader locked device won't brick my phone then i am ready to go.Just need conformation on what happens if i flash custom krenel and rom in bootloader locked mobile accidentally.

When your rooting status says
"Bootloader unlock allowed: yes"
Then the bootloader is locked..
If it says
"Bootloader unlocked: yes"
Then your bootloader is unlocked..
Simply dial *#*#7378423#*#*
Then find your rooting status..
And I think you should use the official way to unlock bootloader.

HAhaaa unless that shopkeeper imported the phone,unlocked bootloader and flashed a kernel.Place where i live doesn't have authorized sony mobile distributors.So they import from somewhere.
My booloader was unlocked whole time after purchasing it.It was new when i bought but no sure now.Anyway i am satisfied with my purchase a year ago as i haven't got any problem till now except that famous house crack.
I have flashed Cynogenmod successfully.Thank you all for the help.You guys gives some courage for nervous guy like me who are tempting to do new things.

a question about bootloader unlocking/locking

If I flashed the stock MIUI 10 with miflash and by mistake I chose "clean all and lock", and the bootloader got locked again, should I wait again for the waiting period if I want to unlock it?! Or is the waiting period a one-time thing?
Thanks
once you have the permission from Xiaomi! you can unlock again with same procedure!
You have to wait only once to unlock the bootloader after that you can lock and relock bootloader anytime

Ok.
I actually haven't unlocked the bootloader yet, does the waiting time happen after I press the Unlock button on miui unlock app?
Because I once saw something like "getting the permission for your account" and it showed up for less than a minute and it's gone, but I didn't unlock it back then, so my question is, when exactly does the waiting period happen? Thanks a lot

Thanks, this helps a lot, when locking the bootloader again, does the device show locked or relocked in bootloader status? (like Huawei devices)
