LT15i Locked bootloader help please - Xperia Arc Q&A, Help & Troubleshooting

Hi all,
I have read many threads on this page, and developers pages, however, it seems quite difficult to unlock this O2 LT15i so I can install ICS.
I have tired and failed.
Is there anyone that might be able to spend a little time talking me through the steps to do so.
I just wish this phone was unlocked as if it was, it appears simpler.
PLEASE can anyone help, or suggest a step by step guide. (for novices like me) that really want the phone working well, but arent 100% clued up on all the softwares.
I understand the process of installing ICS to phones, as I have done so with my HTC HD2 (workked very well in under an hour). but this LT15i is something else!!!
Please help.
(sorry if this has been posted before, but I have honestly tried howevver, the guides I used have missing links, or trojans in the downloads
Kind regards
P

forgot to mention Bootloader unlock allowed says NO.
Whats my first step?
I follow all the other guides and they all have yes as the answer....

Bootloader & SIM Unlocking:
PLEASE NOTE: The ONLY WAY to Sim Unlock your Phone is to PAY for it, so do some Googling and read which services have been recommended in the past.
PLEASE ALSO NOTE:
If you're Phone was manufactured AFTER a certain date, 12W11 (look under your battery for a similar number) then the Testpoint method no longer works, and People who have had Phones returned from a Service Centre are reporting that they can no longer unlock via the Testpoint method either.
- Know Your Android Bootloader - What it is and Why it Matters
There are three ways to Unlock yours, the Standard/Official method (For SimFree/Un-Branded Phones) which is explained HERE, (PLEASE NOTE! - You loose DRM when using the official method but not with the TestPoint) but if your Phone came from a Carrier then chances are (99%) you won't be able to use that method. There is a simple method of checking if you can or not which you'll find HERE.
Standard Unlocking:
Then there is the TestPoint method...
TestPoint Unlocking:
Two members - Alejandrissimo or Jinx13 offer a Remote Service which isn't free, but cheaper than anywhere else on the net, and when you take in to account you will also SIM Unlock and retain DRM using the Remote method it's worth it.

Hey buddy, you don't need to unlock your boot loader before you install a custom ROM or upgrade your phone to a custom firmware, all you need is to get rooted and download the ful ROM, then with the help of flashtool, your done. Am currently running a custom ROM (viper xperia) which is blazingly fast and lovely UI with my Lt15i locked bootloader.

do you by chance have a link to it?
and also, i need to unlock it so i can use it on a different carrier
thanks
its stickied at this section. the top thread.
easiest and cheapest way to unlock is to use omnius but this will also unlock your bootloader but it can always be locked again.
here is link to the guide about arc
http://forum.xda-developers.com/showthread.php?t=1133650
Not much to do except themeing and rooting at the moment for a stable phone.
My suggestion is to just use it as it is because the battery life is awesome with stock ROM. I had timescape and other junk uninstalled.
There is not as much development going on for arc as for the x10 at the moment.

If you can unlock the bootloader then you should look at installed doomlords kernel... allows you to overclock the CPU.. amongst other things!
thanks everyone for your help
i really appreciate it
i followed the namaste tutorial and now have a rooted arc with 3.0.A.2.181 generic firmware
my next question and probably most important one
how do i unlock the phone to use on a different carrier?
when i insert my sim from other carrier it asks for SIM unlock code? do i have to call them to get this?
thanks again
No mate, you must buy an unlock code from a trusted website.
I highly doubt the carriers will give you an unlock code.
any recommendations for a site to get the unlock code?
Not sure why you bought a brand new locked phone to a carrier you don't use? How strange. Anyway, your carrier should sell you an unlock code. In the UK this is usually GBP15.
I would also avoid fiddling too much with custom firmware - what little exists is very early in development and rather rough. The stock SE firmware is actually very good.
The most I would do if you want to debrand is to flash a generic stock SE ROM and then actually use your phone and enjoy it.
thanks alot
i did flash it with generic rom. so thats good to go
i still dont know why i rooted it because i dont see a use for it so far... will have to wait and see
any experience with Cellunlocker.net?
Yes - I used them. I got the code in the end but it took ages - maybe it will be different now. It was expensive though. Doesn't Omnius-Server unlock phones and you get the bootloader unlocked at the same time - its way cheaper than cellunlocker too.

not sure why its blocked but just contact him directly here in xda-forums.
"sim unlock" allows your phone to use any networks and not just where your phone was subsidized from. means can use any sim card and network worldwide. of course if you will just stick to your current provider and not intend to go to other country and use the sims there, maybe you will not need sim unlock. also, a sim unlocked phone has more value in terms of resale.
"bootloader unlock" allows your phone to be programmed to use other software or system which is either a modified form of software from Sony Ericssson (often with enhancement) or even a whole new system for the phone which makes it look and work differently from the original. it is for more technically expert users.
For me, i am ok with Sony Ericsson stock, but I do appreciate the bootloader unlock as it allows me to flash doomlord's kernel makes downclock phone max speed possible to save battery life. it also gives root access already which offers full control of the programs running in the phone.
For your requirement, sim unlock is enough. But I believe Blagus solution when done, does already a sim unlock AND enables the phone to be bootloader unlocked. Note that it just "enables unlocking", its still choice to have it remained in locked state. Because sim locked phones have locked bootloaders and cannot be unlocked using the Sony Ericsson publicly provided procedures.

Unlocking bootloader Q's

Hello,
New to xda and the modding scene. Just got my Arc about a month ago and I LOVE it! Pretty keen on putting some mods on it but my qustion is, can I unlock the bootloader, root, etc on a simlocked phone? Mine is locked to Optus AU.
Thanks!!!
You need first to sim unlock your phone
From my sexy LT15i
Awesome thanks. Turns out that my phone is unlocked after all Time to load it up with mods
Aha, nice
From my sexy LT15i
Before going nuts on modifying your phone you need to ask yourself if you want to root+unlock bootloader or just root... Not all xperia phones can have their bootloaders unlocked (if your phone was sold by a carrier i.e. branded such as Rogers then you will NOT be able to unlock your bootloader... Technically there is a test point method but it is quite the procedure compared to simply unlocking it the simple way that Sony offers). In the newbie guide it explains if you root your xperia but not bootloader unlock it you can only install custom roms for stock kernels, although if you wanted say ICS beta rom that Sony released then you would NEED an ISC kernel which is only possible to get on your phone after bootloader unlocking...

[Q] How to unlock Xperia Play R800at bootloader?

Hi im DVE and I am new to this XDA stuff etc... I was wondering if anyone can help me out with how to unlock the Xperia Play At&t Bootloader so I can install ICS or Jellybean on my phone for I'm tired of and stuck using gingerbread 2.3 Any suggestions?
To my knowledge the R800at is the only model that does not let you use Sony's unlock site to unlock the bootloader. You need to hit up an XDA member by the name of Alejandrissimo and talk with him via Google Talk, he can unlock it for your remotely for free. Via the touchpoint method.
Check the Sony site and see if they are allowing AT&T users to unlock now:
http://unlockbootloader.sonymobile.com/
Good luck.
Edit - Wotan Server has all the files you need to download and install the drivers for the Xperia PLAY to be recognized in your PC. It also will provide you with the files needed for Alejandrissimo to unlock your phones bootloader.
http://www.wotanserver.com/en/sony-ericsson/xperia-play-r800/unlock-tool/debranding-flash
Install the file listed on the above link, and when its installing it will install ALL drivers for Sony Ericsson phones. It will pop up several windows asking you to verify you want to install the drivers, select "ignore warning and install"... or however its read.
I appreciate your reply I really do I'm just sick of gingerbread and would like to try out custom roms one day lol!

If you want to take the full tour of custom roms, many do not require a unlocked bootloader. But for the best its best to unlock. Seriously if you get stuck, contact alejandrissimo, he is awesome. Very patient and will help you to unlock your phones bootloader.
Other Solutions to unlocking R800at bootloader?
I got another question to ask ya, what if I try this website:
fast gm (dot) com
It says to pay 5 dollars for a unlock code to get rid of the At&t off of my phone via network etc... will this unlock my bootloader as well?
I mean if anything or any website that states unlocking are they referring to the bootloader too?
I have a at&t r800at too i want to unlook
i want to unlook bootloader
me too! sick of gingerbread!
Thanks for telling me about Alejandrissimo. I have moved on to a Galaxy Note 3 N900T without ever trying custom ROMs on my old Xperia PLAY R800at (despite my constant frustrations with the generic North American R800a ROM). I wanted to experiment now that it's not my daily driver but I did not want to spend $30 at some unlocked site for a phone I'm not even using. The FTF method doesn't seem flexible enough to try everything I want to try.
unlock bootloader
Hi, is there posible to unlock bootloader for free?? Or a guide to unlock it??
If you want to unlock the bootloader go to the sony site. Or if you want to unlock for free use the testpoint method.
Test point is an old trick and there are many guides on youtube. Once unlocked it will appear to still be locked. However you cannot install all roms only the ones that have been converted. If you search LOopy in the forum you should find the thread whoch contains all the roms.
That is how I unlocked my r800at it also preserves drm.

It seems that you've worded that weird. I'm under the impression that sony still doesn't offer a way to unlock the r800at. Also, saying testpoint method is free, directly after, seems to infer sony charges for unlock. That, would also, be news to me heh.
But i also have unlocked my r800at bootloader with setool! Just tonight, also thanks to some info from your posts, thanks again.
This being the case, I think that services like Omnius, Wotan, and Alejandrissimo, should be referred to as either; "fastboot installation" or "fastboot unlocking". Bringing me to my original point, It seems sony; or maybe even the company of motherboard (i think qualcomm?), should have to release this "fastboot unlock/install". Recently a legislation deadline with carriers being forced to allow unlocks was met, feb 10 i think. I plan to link articles in a post soon.

[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.
dialed *#*#7378423#*#* and found my phone is BOOTLOCKER ENABLED=NO
Asked o2 for a Sim Unlock Code
Entered that unlock code sucssesfuly
re dialed the num in point one to find that is sill says no
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.

oh okay thats wallright then mines an 11W18
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.

[Q] Can i flash Jelly Bean on my XPeria Arc S no bootloader

Is it possible to somehow change my android from ICS to custom Jelly Bean on my phone
Sony Xperia Arc S LT18i, Production date code 12W22
It came up with Android Gingerbread on board.
What i did so far is using program called Flashtool to flash my phone with stock Android ICS 4.0.4 4.1.B.0.587 (the file was called Android_4.0.4_LT18i_4.1.B.0.587.tft). This replaced branded Gingerbread with non branded stock ICS
After that i used Flashtool to flash my phone with Kernel 4.1.A.0.562 and then i used DooMLoRD_v1_Xperia-2011-ICS-ROOT tool to root my phone.
And after that i flashed it with 4.1.B.0.587 kernel.
By doing this steps i supposedly achieved root on my phone (superuser and root checking apps show full access).
Now i read about flashing with Jelly Bean custom roms and all i seen mention "bootloader"
When i open secret service menu on my phone there are two things that worry me:
- Simlock - it says my phone is provider locked
- Bootloader unlockable - NO
So this is my question, is there any way in my current situation to somehow flash my phone with android Jelly Bean? In a similar way that i used to upgrade it from gingerbread to ICS?
Hi !
In order to flash a Jelly Bean ROM on your phone, your bootloader needs to be unlocked. There is no other way.
As you said, you can't unlock it the "easy" way. Nevertheless, I think that there are other ways for you to unlock it.
You can follow this guide : http://forum.xda-developers.com/showthread.php?p=35910775 > Bootloader and SIM Unlocking.
You should give a try to the testpoint method /!\ DO IT AT YOUR OWN RISK /!\
I never tested it myself.
If it works, you would be able to flash a custom kernel through FlashTool and flash a JB or even KitKat ROM.
Hope I helped.
Cheers.

Thanks for reply, unfortunatly it seems that this:
"If you're Phone was manufactured AFTER a certain date, 12W11 (look under your battery for a similar number) then the Testpoint method no longer works"
prevents me from using testpoint method because my production date code is date 12W22 which seems to be newer than 12W11.
Also the article mentions Two members - Alejandrissimo or Jinx13. I checked it with Jinx13 and he confirmed that there is no way for him to unlock bootloader from that production date phone, i didnt contact Alejandrissimo yet.
I dont mind paying for online/remote service, i know that experience and knowledge costs, im just looking to way for getting my bootloader unlocked.

You are one of those unfortunate people, who can't unlock their bootloader at all due to certain restrictions.
We do not have any confirmed solution for test point method, however there is one topic in General section of Xperia Arc, where the OP claims he managed to unlock the bootloader in such situation. You can check it out, however it is your own decision, if you try it or not.
