any ideas whats wrong or what im doing wrong thanks paul
[Xperia Arc General] Step666:
That's the problem, you're typing your IMEI in instead of the unlocking code.

Go back and look at the instructions, particularly steps 2-4.
[Xperia Arc General] faulkner23:
my bad all done thanks very much feel really silly now hahaha
[Xperia Arc General] Step666:
It happens - it's a shiny new toy, you're happy and excited and you just get ahead of yourself.

We've all done it.
[Xperia Arc General] Gig11gs:
trying to unlock and for some reason it says invalid IMEI maybe its already unlocked? because i can reach fast boot with blue LED (when i hold menu and plug in USB) but black screen.. i have no idea if it locked or not :S... how to chick if i have an unlocked boot loader?

btw got my phone from Dubai sim free.
[Xperia Arc General] :
Remember that only the first 14 digits of your IMEI are required.
[Xperia Arc General] Gig11gs:
oh ok got it

thanks unlocked now :D
[Xperia Arc General] ChefChaudart:
Hello,

I´m blocked at point 8.

On my W7 64 bits, I´ve seen that driver installation failed.:(

What can I do ?

Secondly, I tried Sony´s way, but where to put usb driver in Android sidekick, there is none !?

Cheers
[Xperia Arc General] Step666:
Did you download the drivers lollylost linked-to?

I'm running Win7 x64 and they did the trick for me...
[Xperia Arc General] ChefChaudart:
Yep !

Anyway, I did it on an old XP machine, where it worked perfectly, thanks :)
[Xperia Arc General] phonex1:
Has anyone with a carrier locked phone tried debranding, then connecting to fastboot and unlocking the bootloader? I think after 1st page there was no further comments on that. Sorry if I missed anything.

Thanks! :)
[Xperia Arc General] Nimche:
could someone please remind me how to install those drivers for win7 X64 bit I searched this thread without any answers.

Thanks

EDIT: I got it done SE style with Android SDK and updated driver with what is there.

It worked/
[Xperia Arc General] kenjichui:
hi, the unlock page shows INVALID IMEI, PLEASE TRY AGAIN.. .

i got my arc from starhub.

is it locked?
[Xperia Arc General] hush66:
You only need to enter the first 14 digits of your IMEI.
[Xperia Arc General] Rithina:
no need so hurry to unlock first. Let wait for the root exploit first

[Xperia Arc General] El_Gorgon:
Hi lolly, my arc doesnt go into fastboot, after a few seconds with green light it becames charging...the fastboot exe stays waiting device...i have a debranded one from vodafone,and put generic one,what can i do...maybe driver problem?
[Xperia Arc General] :
Only SIM Free devices have fastboot mode.

@kiz1983 - you will be able to update using FlashTool :).
[Xperia Arc General] El_Gorgon:
It is from vodafone but i got it free by introducing the code...but it doesnt work anyway...:-(
[Xperia Arc General] :
Like you said. It's from Vodafone, not SIM Free. Even if unlocked and debranded, it's still a Vodafone handset.
[Xperia Arc General] El_Gorgon:
that´s what i suspected....:-(

So, any hope for us?

G.
[Xperia Arc General] :
No solution for you yet.
[Xperia Arc General] RandyboY:
Thanks for this easy to understand how-to :-)

Where do we find ROM's? I would _very_ much like to find a ROM with lates Sense i can use on my Arc. I'm comming from Desire and i miss the HTC Sense(everything about it) :-)
[Xperia Arc General] Larsiano:
Hey Guys!

I'm on my way to unlock the Bootloader on my Arc, but stucked now and don't know how to get further on.

I'm on the part where you have to point Windows to the drivers.

I’m doing it exactly how it is described, but during the load, when i guided the system to

"android_winusb.inf-file"

, it said that the “WinUSBCoInstaller.dll” is missed. I have looked across all the folders on SDK, but it's definitely not present there.

I already know, that this file should be a part of the “Google USB Driver package, revision 4”, but it isn't there. I installed and reinstalled it, in many different ways for the last 2 hours… just to have it in, but It's not there.

Please can someone help me a bit?

I'm apologizing to ask such a noob question, I don't want to bother you guys or be a burden for anyone, I just couldn't find out a solution.

I'm also trying much things all alone, just to figure it out by myself but unfortunately that's my limit…

Many Thanks in advance.

Best Regards

Lars
[Xperia Arc General] funkyblue04:
Stupid SE. I am regretting buying this phone. I have a NEO and cannot get it to unlock the bootloader. I already have the Android SDK installed. I can get it to display "SEMC Flash Device" and update the software but not unlock the bootloader. I want to root this phone. What do they not just release a simple tool to download and unlock the bootloader? I should have purchased a Desire S.
[Xperia Arc General] Step666:
Is your handset network-locked?
[Xperia Arc General] HYPER-X10:
SE intend for developers to unlock the phone.

I'm far from a developer, but I managed to do it no problem.

I think it's a case of stupid funkyblue04, rather than stupid SE.

Have you tried the root method that doesn't require unlocked bootloader?
[Xperia Arc General] kiz1983:
about the part where windows need to find the required files for the drivers, its in the x86/x64 drivers that lolly provided..

you don't need to go through all the steps in the sony ericsson website, you just need the unlock key from it, that's all..

then proceed with the steps where you extract the fastboot.rar, and so on..
[Xperia Arc General] funkyblue04:
I do not appreciate being call stupid thank you.

I have tried the bootloader method as directed by SE but cannot get my phone into the right mode. Fastboot is stuck on waiting for device. I already have Android SDK installed, so it did not update drivers.

I also tried the Gingeroot APK but get the errors

"could not extract assets"

Then I get premission denied when trying the commands the posts suggests. Shell just comes up permission denied.

It's frustrating.
[Xperia Arc General] funkyblue04:
I managed to get the bootloader unlocked. It turns out I was suppose to puse the "search" button and not the "menu/home" button as described. Just have to try and get the root sorted now.
[Xperia Arc General] Nimche:
the right button is Menu button(it is used for search but main function is Menu)
[Xperia Arc General] funkyblue04:
Yeah I got that. Just never used it as a "menu" button before. In anycase, ths boot unlocking guide and the other thread have allowed me too root my Sony Xperia NEO. Thanks everyone :)
[Xperia Arc General] Step666:
The Neo doesn't have a Search button.

The button layout is identical to the Arc - from left to right: Back, Home, Menu.

Of the three new Xperia handsets, only the Play has a dedicated Search button.
[Xperia Arc General] Larsiano:
First of all, thanks for your help!

The problem now is just that my PC is currently running on a Windows XP x32, which means that the driver package from lollylost100 will take no effect.

But anyway, when it means that I have to install a x64 or x86 OS version, then I will definitely do it.
[Xperia Arc General] :
x86 = 32bit :).
[Xperia Arc General] Larsiano:
ohhh....yes...right...my bad ^^
[Xperia Arc General] tonetu:
Thank you for your efforts ..

Well, never worked with me, i reach the final step and get error:

I tried everything written here, followed the instructions step by step, mobile is connected, blue LED is there, got the KEY from SE, everything .. just dont wana work :/

Am using windows 7, my mobile bought from Hong Kong ..

Hope someone can help.
[Xperia Arc General] kiz1983:
i guess ur phone cant b unlocked..

if u wanna root, can try gingerbreak tho..
[Xperia Arc General] :
Kiz1983 - bull****.

Tonetu - What is the exact command you are entering? Paste it in here with the key.
[Xperia Arc General] kiz1983:
lolly..

sori if thr is a misunderstanding, wht i mean is whether his phone is locked to a carrier or not...

if its locked, like someone said, u can get the number from se website but u cant unlocked it...
[Xperia Arc General] :
Look at what he said. His phone enters fastboot fine. Either incorrect command and/or incorrect key.
[Xperia Arc General] kiz1983:
oh ok, sori my bad >.<
[Xperia Arc General] laurence0609:

[Xperia Arc General] naboleo:
Guys, does someone have a trick for a phone that can't be turn on in fastboot mode ?

Phone is now with a generic rom (same than the video) and has been simunlocked.... Even the command lines "adb reboot bootloader" and "adb reboot-bootloader" are simply reboot the device.

Also note that root is ok with gingerbreak

Any advice/clue ?

The handset was a dev handset from SE... could this be a problem?
[Xperia Arc General] Step666:
A Dev handset?

Care to elaborate?
[Xperia Arc General] :
If you're code request was successful then it's just an ordinary device. Try again but with typing the command instead of pasting (or vice versa).
[Xperia Arc General] dedhandi:
Got sent it from SE a few months back for development purposes. Current software is buggy as hell and crashes regularly so really wanted to reflash. Previous experience with SE pre-release handsets is that months/years later when you try to update them using their own update software, you can't - presumably because they've disabled it?
[Xperia Arc General] :
Just FlashTool for a simple reflash :).
[Xperia Arc General] dedhandi:
Thanks that seems to have been successful! So, just to humour me with an explanation, why do you need to go through the whole process of unlocking the bootloader etc, if you can just reflash using FlashTool?
[Xperia Arc General] :
To flash firmware which hasnt been approved using SE's signing certificates. This way anyone who compiles a working .img can flash it to the phone.
[Xperia Arc General] law910:
I am have the same problem this site: http://www.xperiablog.net/2011/04/18/unlocking-bootloader-is-a-one-way-process/

says that SE claims we can still update via SEUS as long as we have SE rom.. but I come across the same message saying that i have modified firmware..

Can someone please help???
[Xperia Arc General] :
You can use Flashtool instead.
[Xperia Arc General] law910:
thanks for that but is there a way to get SEUS working again as SE claims?

[Xperia Arc General] Nimche:
This is freaky now.

I called customer service and for service she asked for my IMEI number and I gave it to her but she CAN'T find any record of my phone? How is that possible...?

Anyone else has tried this?
[Xperia Arc General] zenkinz:
I have just placed an order for arc and am right now doing all the necessary research to root the phone.

It looks like unlock bootloader is the first step. Does all arc comes with a locked bootloader?

Edit: I read from other thread that unlock bootloader is not needed to root.hopefully I could use flashtool to update cm7 instead of relying on unlock bootloader? Really hope I don't need to mod something that is irreversible.
[Xperia Arc General] Nimche:
either of the two condition:

Your SE arc is unbranded = bootloader unlockable

Your SE arc is branded = bootloader NOT unlockable YET

For root, you don't need bootloader modification just use that Gingerbreak and it works flawlessly on 2.3.2

are you the same zenkinz developer from PointUI?

Hope you enjoy your new phone.
[Xperia Arc General] zenkinz:
Yes same zenkinz :)
[Xperia Arc General] dantevip59:
Hi I have a question, I did unlock my ARC successes, however, when I restart the phone, the boot screen was processing so long (around 30 minutes or more), and then it finally got into the system, it suppose to show the setting menu but mine has NOTHING, nothing means the screen was blank but only has "no service" on the top, all the bottons were not working except the power botton, when I push the power botton, it only has turn off the phone option. I tried fastboot to flash the O2 Rom, but it only shows waiting for device. I have no idea how to recover my phone right now. Is anyone can help my problem?

Ps. sorry I can't explain very well in English but hope someone can understand my problem.

If I buy one with software branding but without simlock, will it be bootloader unlockable after debranding?
[Xperia Arc General] Step666:
Ain't no such thing.

All branded handsets are SIM-locked and thus cannot have their bootloaders unlocked.
[Xperia Arc General] Flo95:
Not here in Germany...

Anyway, regarding to a german forum an Arc with T-Mobile branding is unlockable :) (Found the post there after asking here)

My apologizes in advance if any one answered this question already. I have a Rogers (Canada) Xperia Play R800a, build 3.0.1.A.0.145.

I have all the necessary things on my pc to get it done just can't seem to get the blue light. If anyone can help me out or send me a link with the help I need it would be very appreciated.

Thanks in advance!
[Xperia Arc General] Step666:
There's nothing you can do.

Network-locked handsets will not enter fastboot mode so it's impossible to unlock the bootloader.

That could change in the future but as things stand, you're stuck.

I have the same problem with some people posted here. I did unlock my phone earlier, then I did the OTA update and had to send it to warranty. (I didn't know that I can fix it without sending it earlier.)

Now I got my phone back but I can't seem to unlock it anymore. I got the 0.3 number, got unlock code from SE website twice, but I always get the same error.

(bootloader) Unlock phone requested
FAILED (remote: oem unlock failed!)

Could it be because of OTA update to 2.3.3? I thought I could simply use GingerBreak but seems like they fixed it. The other methods require unlocking and I can't do it either. And I can't redo my backups with Titanium. Could anybody help me with this?

Bootloader unlock not allowed

Hello guys,

I have a problem to unlock bootloader.

I tried a few days ago with this tutorial but when plugged in the phone + press Menu, just had Orange Led and battery charging.

Today, playing with the phone and goes to Service ( *#*#7378423#*#* ) / Service Info / Configuration, i found a line called Root status with Bootloader unlock allowed : NO.

Is it the source of my problem?

thanxs
[Xperia Arc General] YouZi:
Can I suggest @lollylost100 to mention on the first post, that, unlocking bootloader will wipe drm and stops TrackID and muisclike from working?

I understood that unlocking bootloader will wipe my data, but I didn't know that loosing drm will effect some build-in apps such as TrackID.

I guess it would be better if the op can give some warning in the first post.

[Xperia Arc General] toxicstone:
I cant get it to work, im following the steps, but when im holding down the menu button and connect the phone it just connect with green light, just like when im not pressing any button, and i see the charging logo.

it response to the left button (back) and appears "driver couldnt be installed" or something with the s1 download but no fastboot , so it respones to the left button but not the right.

dunno what to do, i have the command window open if that mathers.

Edit: NOW Not even the s1 download appears, it doesnt recognise the phone, until i let the button.

Im confused, hope to get helpt, just trying to unlock this to my sis.
