Default [HELP] Unlock Bootloader: NO/ Rooting Problems SE Xperia Arc (LT15i)

Hi,

First off sorry for any reposts is didnt know what else to do after reading forum posts for hours and hours.

So heres the Crack. I'm tring to flash CM 9 onto my SE Xperia Arc (LT15i) and so far here is what i have done.
  1. dialed *#*#7378423#*#* and found my phone is BOOTLOCKER ENABLED=NO
  2. Asked o2 for a Sim Unlock Code
  3. Entered that unlock code sucssesfuly
  4. re dialed the num in point one to find that is sill says no
  5. tried putting into fastboot anyway (as suggested by users in another post)

I'm other things i did where email and ring o2 both gave me no help and email sony mobile and recive no reply after now a week and a half
does anyone have any tips on turning the boot loader to say yes as that is my only hurdle to rooting this phone, i believe it is possible as i read a page on the sony forums sayinf a spansih comanpy called movistar was offering it for there customers however i then though one last ditch attempt with o2 on there forums where the customer service lady flatout refuses knowlage of a bootloader.

in summery a) sorry for rambling a little b) is it even possible by any means to change the UNLOCK BOOTLOADER: NO to UNLOCK BOOTLOADER: YES. and if so how?? c) sorry again if this is a duplicate post i didnt know what else to do at this stage.

If the SIM unlock was successful you should be able to unlock your bootloader. Just follow the steps here:

Actually no. Just removing the SIM-lock does not enable fastboot (and does not change Bootloader Unlock Allowed, it still stays on No).

The only way to unlock bootloader is by using test point method, if your phone is manufactured before 12W11 (11th week of 2012). You can check it under the battery. If your phone is manufactured after 12W11, then you can not unlock your bootloader and can only use stock-based ROMs.

There is no known solution to this at the moment and due to lack of interest by developers, it is highly unlikely someone will work on it.

It seems like i found the solution.


you have to pay 10 via paypal on phoneunlockserver(dot)com
and he will log on to you computer via himatchi and you put your tweezers on the test point (for the arc its under the sim card) and then plug into the usb and he flashes a kernal or something.


i havn't tried this out yet but if anyone has please let me know how it went

This is called the test point method. It only works on phones manufactured before 12W11.

No need to remove SIM-lock, just find the guide to unlock bootloader via test point method using S1Tool. Follow the guide and it should work.
You can do it pretty much by yourself, no need to pay, if I remember correctly.
