Hi all.
So I have an lt15i with rooted
4.1.b/ 4.0.4 locked bootloader.
The provider is rogers Canada.
As far as I know this provider has made it impossible for me to unlock
My bootloader. But I have also been reading that I just need recovery mode to unlock it. Thanks to the new cwm installer I can now get recovery and have backed up and flashed a ui mod.
So what I am asking is under these circumstances can I unlock my bootloader?.
If so how would I go about trying without bricking or loosing cwm backup?

Well I think so that you can't unlock your boot loader ! And so if you do,you can install any kernel to retain Cwm backup or install from auto installer again!
Ok. What I'm mainly asking is I have a locked BL and most methods I have seen to unlock BL needs recovery mode. Normally I cannot enter recovery but the cwm auto install allows me to enter recovery now. So basically what else does unlocking the BL need beside recovery mode?

Bump..
Any thoughts. I don't wanna go into trying it blind.

Strictly speaking it's the other way round, you need your bootloader unlocked to enter recovery. Recovery lets you flash roms, not kernels, and to unlock you either use the Sony site(official) or testpoint(unofficial).

I believe it is flash mode that allows you to flash roms. And recovery(blue light) allows BL unlock then I can flash kernels.
I can both get into flash mode and have 4.0.4 rooted witch I flashed.
But normally booting with vol down does nothing but after cwm install I can boot holding gold down to enter recovery where cwm sits and am able to flash zips and update.zips.
Now so far this seems I can flash an update zip to unlock my bootloader. I am wondering if thia will brixk the device because I am tricking it because in my service menu it says BL unlock no.
If no one has a clue I will try it out.

I was in android development and was reading an article it says
" to install just go in recovery and click on install zip"
How on earth do you even get recovery on ARC in the first place ?
please help and straight set of instruction would be appreciated.
Thanks in Advance
Hey mate
Only way at the mo is by unlocking bootloader and flashing doomkernel thru fastboot.
That will give u root ,recovery,oc etc
If ya have sim free arc bootloader can be unlocked on se website otherwise you will have to pay one of the devs to do it for ya thru omnius or setools
That enables fastboot on ur phone which is the only way to flash kernels at the mo

when you bootloader is unlocked you can also run CWM on your phone without flashing the Doomkernel.
fastboot can boot your phone in recovery without flashing it, you have to have a boot.img with recovery in it and than : fastboot boot boot.img
this way you can keep everything on your phone stock but you ill have to do this every time you want to enter recovery
im in stock GB with unloked bootloader
If i update my phone using pc companion....
will I have to re unlock my bootloader..????
U cant update with an unlocked bootloader. Some ppl said that it will kill ur phone. But, in my experienced, a pop up alert message show up at my pc screen saying "phone cant update coz a few stuff has been altered" or someting like that.

Im having custom kernal and root...
Should I have to remove them aswell...
Thanx for replying.....
Geez people, you should research before this.
Here's a thread in the General section with How to install and root: http://forum.xda-developers.com/showthread.php?t=1683957
That's for Stock ROM and Kernel.
If you wish, you can flash the ROM, then use fastboot to install a custom Kernel from the development thread which most likely will have CWM that allows you to flash RootXperia.zip and that's about it.
Unlocked bootloader makes everything easier.

I recomend u flash a stock GB firmware first, for example firmware .42, and then u relock the bootloder. After that, update, and the unlock the bootloader again

If you have an unlocked bootloader, why not just flash the 4.0.4 ICS using Flashtool? There's no point in locking your bootloader, then updating and again unlocking it.
Just flashing the .ftf is much simpler and doesn't waste your time.
So I've finally decided to unlock my bootloader so I've been reading a few threads about it but I want to be sure that I'll do it right.
I want to use this method:
http://forum.xda-developers.com/showthread.php?p=12873655
But since I'm on a branded phone I understood that I'll have to flash a generic Rom first to allow the unlocking to be done, am I correct?
I do understand that I'll lose the DRM's and stuff and that while on an unlocked bootloader I cannot use official SE programs (PCC & SEUS) because it will brick the phone correct?
After the unlocking is done I'll still have a fw installed right?
And finally, after unlocking bootloader I'll flash roms in flash mode and kernels and baseband on flashboot mode right?
Thanks for the help guys!

Things I have done.
Rooted and installed CWM for Locked Bootloaders
Tried to install a rom but CWM was rubbish and it failed.
Recovered a .45 rom using flashtool.
Rooted and put CWM on again.
Unlocked bootloader using fastboot........
Once device rebooted it gets as far as Xperia logo and reboots, and reboots etc.
I can access recovery but its useless!
Whats my best step to do next??

#Check the status of your bootloader, like if its already Unlocked or Allowed, if its Unlocked then proceed STEP 02 and if not then Unlock the Bootloader First..You can search the thread around here on how to Unlock Bootloader. Dial *#*#7378423#*#* to check your bootloader Status. It will say Bootloader Unlocked : Yes Or Bootloader Unlocked Allowed : Yes or Simply NO.
# ReFlash your firmware with Flashtool & reboot
#Fastboot your desired kernel to get root access..you can fastboot your stock kernel back again if you dont wana use custom kernels. Both ways, u will still have your root access. My advice would be flashing SSpeed Kernel v08 or Advanced Kernel as both are updated kernels of current firmwares and the best CMW obviously!
# Let the kernel set in for some couple of hours
Hope it helped :highfive:
Hi, guys thanks to xda I was able to root my phone now I can't seem find a working CWM recovery file to flash it in my device. I've not unlocked my bootloader though so please help me flash cwm recovery on my c1904 15.4.A.1.9 firmware locked bootloader thanks in advance.
Sorry, but it's impossible to install cwm if your phones bootloader is locked.

i did flash a cwm recovery for my device using flashify.But it just simply reboots it doesn't go to recovery mod. & please do something.
On Stock 4.1 i heared about a CWM for locked bl, but never tried it. But on 4.3 it isnt working. Look for the thread in general section.
But a "normal" CWM on locked bl isnt possible, as the bootloader only loads a kernel from Sony, and to boot into cwm on our device we need to detect an event to extract the cwm ramdisk instead of the nornal ramdisk, which is only possible with a modified kernel, which requires an unlocked bl to get loaded.
