I have unlocked my bootloader from the Arc whit the testpoint method, using the s1tool, so I don't losing the DRM.

For who want to do this, its only for the Arc, not the Arc S.

Do this on your on risk!! I'm not responsible when you brick your phone!!

Only works on generic branded phones.

First download the s1tool Attachment.

Find some wire and a paper-clip, or something like that, and put it together, whit some tape.

Uploaded with ImageShack.us

Now put the other end of the wire between the usb extension cable and your phones data cable. That's for the grounding.

Uploaded with ImageShack.us

Now remove the back cover from your phone and remove your battery and sim-card. Remove the small plastic that's taped on the testpoint (you can tape it back later) Btw, the point that coloured red is the testpoint of the arc.

Uploaded with ImageShack.us

Oke, now we can started.

Let the battery out your phone, and plug the phone cable in to your computer. Put the paper-clip on the testpoint and let it stay there, then put in the cable on your phone. Your computer saying he found a new hardware, then manual choose the drivers. Go to the s1tool/USBFlash_driver folder and choose your driver. (choose manually, because windows won't find the driver if you let it auto detect).

Uploaded with ImageShack.us

Now the driver is installed, plug out the cable from your phone, but not from your computer. Start s1tool en click on Patch SEMCBoot, then click on Testpoint READY

Uploaded with ImageShack.us

Now put the paper-clip back on the testpoint and plug the cable back in to the phone. Now s1tool is working, and when he say to remove the testpoint, do it. You will see something like the picture below, and when it says its Finnish, you can plug out your phone.

Uploaded with ImageShack.us

Now you can put back the tape over the testpoint. Put in the sim-card and battery. Now you have a unlocked bootloader whit DRM.

If you want to lock it again, open s1tool and click on RESTORE. Power down your phone, press the BACK BUTTON and hold it, then plug in your phone to the computer, then a few seconds later it will say your bootloader is locked again.

When you want to relock the boot-loader, be sure you flash back to stock, outer wise your phone don't start whit a custom kernel.

I hope my English is good enough for the people to understand:p.

Now thats what i call a fully made guide

[Xperia Arc General] jimbo77:
Is the use of S1tool to unlock the Bootloader free? Or do I have to buy some sort of Credits to perform the operation?

Thanks for the help!
[Xperia Arc General] spit85:
It is a free tool.

It Supports:

X10 Xperia,E10 Mini,E15 Xperia X8,U20 Mini Pro

LT15 Xperia ARC,MT15 Xperia NEO,R800 Xperia PLAY

ST18 Xperia RAY,ST15 Xperia Mini,SK17 Xperia Mini Pro.

But I only tested it on my on LT15 (Xperia Arc), so I don't know how it works on the other models.
[Xperia Arc General] spit85:
Btw, If you want to know if unlocking the bootloader was a success; try to go in fast-boot mode, if it works, you can access the fast-boot mode and flash custom kernels. When it wasn't a success, you can't go to fast-boot mode, or flash kernels.

I tried it a couple of times (lock and unlock the boot-loader), and it always work fine for me.

When you want to relock the boot-loader, be sure you flash back to stock, outer wise your phone don't start whit a custom kernel.
[Xperia Arc General] Flo95:
You mean you can't go in fastboot mode and you can't flash a custom kernel, don't you? ;)
[Xperia Arc General] spit85:
Yes, when it wasn't a success, you can't. Sorry, my English isn't the best:p

Aber dafür kann ich gut Deutsch :p
[Xperia Arc General] TheHaso:
With this method can ota/fota be performed ?

Readed it somewhere...

From my sexy LT15i
[Xperia Arc General] spit85:
In theory, yes (the Sony Ericsson way OTA or SEUS). But I haven't tried it, because I don't want to risk a phone brick. I removed the update app from my phone, to be sure it don't update whit OTA. You can try it at your on risk, but my advise: don't try it, because I don't know it sure for 100%.

If you want to flash updates, you can use WotanClient from http://www.wotanserver.com In this clip a guy explain how to use the WotanClient

https://www.youtube.com/watch?v=ZQIw608rZfI

Btw, I'm not sure if it harms to flash whit WotanClient on a unlocked boot-loader. I relocked it, updated whit WotanClient, then unlocked it again, and that works fine for me :)
[Xperia Arc General] Flo95:
No problem. Just wanted to correct it for other people.

Sehr gut :)

Ich kann niederländisch ein bisschen verstehen, aber nicht schreiben :D
[Xperia Arc General] spit85:
Nothing wrong about that, because people must understand what I writing down.

Meine Mutti ist Deutsch, also verstehe ich es:p
[Xperia Arc General] Retrosid:
Is it needed to use the cable with the paperclip and the usb cable? You can use as grounding the metal part on the sim card

Sent from my Xperia Arc
[Xperia Arc General] spit85:
Yes that can, but it's tricky that way, because you must hold the paperclip at two points, but you can try
[Xperia Arc General] TheHaso:
Waaait, wait, some poeople had issues with the simcard detection after using that as ground.

I suggest not to use that metalplate!!

From my sexy LT15i

[Xperia Arc General] corey1486:
I tried this on my arc, did not work. Will this only work on sim free phones?
[Xperia Arc General] spit85:
S1tool only works on generic branded phones, so your phone must aloude to unlock the bootloader. Open your dailer and enter *#*#7378423#*#* to access the service menu. Tap to service Info> configuration> rooting status. If bootloader unlock allowed say yes, then you can unlock your bootloader, otherwise you can't.

But carrier branded phones can't unlocked whit s1tool, then you must use the payt version, the SeTool.
[Xperia Arc General] stirkac:
WOW!

This is amazing and should be Pinned! No one likes to be in unlocked database at Sony.

I am doing this tomorrow :) will report back. I must say this is the easiest ever bootloader unlock without consequences.
[Xperia Arc General] hpcorona:
Wow, amazing guide!

When you read the first post, you read at the beginning that it is only for generic branded phones.
[Xperia Arc General] jayman1986:
So does this DEFINITELY not work with Arc S?
[Xperia Arc General] spit85:
No, I'm sorry, but the lt18 is not supported. S1TOOL is from SeTool, and I don't know if there is a future update for it, that supports the lt18.

SeTool support it, but isn't free.
[Xperia Arc General] mrmojoman:
i want to unlock my BL but at first i need to know some more facts.

is it important to save the other pins of getting in contact with the needle (maybe cover the others with tape)?

so that only the testpoint is in contact with it?

if i want to relock the bl but have a custom rom with custom kernel running...

how can i restore stock kernel before locking and flash to stock rom?

and what's the right order to do it?
[Xperia Arc General] spit85:
You can tape the other points whit tape, so the needle won't touch the other points. But when you don't use a big needle, you don't touch the other points. And when you want to go back to stock, before relock the bootloader, you can use flashtool to go back to generic FW, ore you can use WotanClient, what I have used, so you can flash the latest generic firmware. But never downgrade the Flash from Android 2.3.4 to a lower version, then you get the 0% battery failure. Btw, that even happens when your bootloader still locked.
[Xperia Arc General] mrmojoman:
does it mean stock-kernel is included in stock-rom? i only have to flash a generic FW and then relock the bl?
[Xperia Arc General] spit85:
http://youtube.com/watch?v=ZQIw608rZfI that is a explanation how to flash to a generic FW whit WotanClient. It's not made by me, but that guy explains how to use WotanClient. After flashing back a generic FW whit WotanClient, you can relock your bootloader. But remember, don't downgrade android 2.3.4 to a lower version.
[Xperia Arc General] mrmojoman:
done it yesterday. works great. thx
[Xperia Arc General] sebasgl1:
i have two questions about this... the first one is, can i use the direct port of the pc usb cause i dont have an extender cable? and how can i remove the sticky plastic that cover the test point? i want to try this but i want to be the most careful i can, :)
[Xperia Arc General] spit85:
If it fits, then you can put the wire to the grounded from your computers usb port, but don't put the wire to deep, because it only shut touch the grounding. And the taped plastic on the testpoint, you can pul it off whit a small knife, or something flat. It's easy to remove, just like tape.
[Xperia Arc General] sebasgl1:
ok thanks, that all i need... i would try this when i get to my home

ok i am ready to begin this, its okey to put the wire like this?
[Xperia Arc General] Kriomag:
i think OTA doesnt work ;) i just tried it after bootloader patch... phone went off during update and is dead, cant turn it on, but wotan recognizes it so im trying now to flash it again :) i was so scared...
[Xperia Arc General] Retrosid:
If you unlocked your bootloader and used ota update, you bricked your phone.

Wheres the test point for the Xperia Arc S ? :)

Thanks:)
[Xperia Arc General] spit85:
This tool works only on the Arc, not the Arc S. But if you read the first post you can read it :-P The Arc S can be unlocked by testpoint, but then you need the SeTool to unlock it. SeTool is not free. Search for it, you wil find something on XDA.
[Xperia Arc General] Alejandrissimo:
I can help you with that :)

Just notice guys that the semcboot in this s1tool its old and it will not be updated, this version will not allow you to use OTA updates.
[Xperia Arc General] Qwerty123 \m/:
Although if i use Omnius its free for another 3days

All shall be cool right ? :)

And its a branded phone O2 so faik Omnius will take care of all of that :)

[Xperia Arc General] redblooded06:
Easy

Thank you so much for your tutorial. Its easy to apply. Thanks.

Is there any offer which rom or which karnel to use first ? :D
[Xperia Arc General] spit85:
If s1tool says that it's done, and there a no errors, then your bootloader is unlocked.

Try to go in fastboot mode, then you know if it's worked
[Xperia Arc General] spit85:
You can choose one by your self. I use a stock rom whit a kernel from DooMLoRD, what works fine for me. But you must choose for your one wich rom you like to use.

Is it true that after this operation lost imei?

Wysłane z mojego LT18i za pomocą Tapatalk
[Xperia Arc General] spit85:
A emei doesn't have anything to do whit the bootloader. The emei is a unique id number from your phone, the same that's use whit guarantee. When you buy a phone, then de emei number is behind the battery, or near the sim card holder. And mostly its numbered on the phone box were it's packed in.

[Xperia Arc General] sebasgl1:
Spit, when you talk about fastboot mode, are you talking about the blue led indicator when you turn on your phone with the menu button pressed?

Because I always have the capacity to do it... Jajajaja damn the world of android is very complex
[Xperia Arc General] spit85:
Yes, that's fastboot mode, so you can flash custom kernels and ROMs. If there were no errors while using s1tool, then your phones bootloader is successful unlocked.

Btw, you also can try to flash a custom rom or kernel, and if it's a success, your bootloader is unlocked. If your bootloader isn't unlocked, nothing happens, because then you can't flash custom ROMs or kernels.

Got android sdk, adb, usb drivers installed installed (adb devices returns the device ok)

Run s1tool successfully :)

Booting into fastboot, blue LED. :)

Device manager shows S1 Boot Fastboot as an unknown device. :)

fastboot devices returns nothing. :(

But what's the correct one to choose?

I chose ggsemc.inf, and chose SEMC Flash Device after.

Still no joy when running fastboot devices.

Maybe i chose the wrong one?

[EDIT]

Got it working!

Used a different set of fastboot drivers (from link in comments of this video: http://www.youtube.com/watch?feature=player_embedded&v=dUsA9HxZjJE)

Drivers installed fine and fastboot is finding my device.

Yay!
[Xperia Arc General] spit85:
There is one inf file that you can choose, then there is a compatible list of drivers for your phone. Normally it must work, but maybe a virusscanner is blocking the installation. But you got it work with other drivers, that's what counting.

Bootloader unlock and sim unlock

Hello everyone! I bought Xperia Arc S. My bootloader shows BOOTLOADER UNLOCK ALLOWED NO. Also it is sim unlock to my carrier in Bulgaria (Mobiltel).

Can I use some problem (for example S1Tool) to unlock the bootloader and also to sim-unlock?
[Xperia Arc General] spit85:
For so far I know there is no free tool for it. There are tools that unlock your bootloader and remove the simlock, but the cost money. But this tool doesn't work on a ARC S. Search on XDA, you will find some threat where to find a tool for your phone, and what it cost.

[Xperia Arc General] spit85:
If you unlocked it with s1tool, then you can relock it again, later after the update you can unlock it again. But first make everything stock. If you have a custom kernel and relock the bootloader, your phone doesn't start.

Damn it!

I almost bricked my device.

this method was immune to ota and pc companion update right?

After unlocking bootloader this way, I did an OTA update and ended up bricking my phone. Had to follow jeerpleas guide to make phone work again.

Now I am afraid to do an update via pc companion.

Guys help me. What is to be done/
[Xperia Arc General] xtacy!:
Once you unlock the bootloader, don't accept OTA updates. Not sure about SEUS but I think that's a no as well.

The advantage of this method was that you didn't lose your DRM keys.

Use Flashtool or adb to flash ROMs, kernels etc.
[Xperia Arc General] spit85:
SEUS and OTA don't work anymore if your bootloader is unlocked. If you unlocked the bootloader the official way, the Sony Ericsson way, then you cannot use SEUS or OTA either. But why you want to unlock the bootloader? For custom kernels? If not, why to unlock the bootloader? Just relock your bootloader, then you can use SEUS and OTA again.

Typed down from the sky with sexy LT15i

Losing DRM is dangerous and having a.risk of warranty

No, it's not dangerous to lose your DRM. It's that a few apps need a DRM key to work. Unlocking your bootloader is a reason to lose your warranty.

[Xperia Arc General] spit85:
Wrong section.

If you want to know how to relock your bootloader, search on the forum, there you will find tools and a guide.

The testpoint method hasn't anything to do with the official method from Sony Ericsson. And you can't use Sony Update Service with a unlocked bootloader. If you relock your bootloader, your DRM still is lost, and there is no way to get your DRM back.
