Possible solution for Fastboot-Windows7 Problems

---

Hi guys, I have found a workaround for those having trouble with installing drivers for fastboot in Windows7. This process requires you to do things in the right order and to be quite fast during some steps, so it may take a couple of goes to understand what you are doing before you nail it. First let me explain what seems to be the problem, to help you understand the method I about about to share with you:

It seems that if the drivers aren't installed in Windows7, the Xperia S will disconnect from fastboot mode, and go back to charging. What we need to do is install drivers in this small time period it does connect to your computer.
The solution to this problem will involve being quick at two stages of this process and I will note where these times are as best I can.
Both these stages are when we connect the phone to the computer in Fastboot mode.

Steps to install drivers:

1. Open device manager
2. Connect you phone in fastboot as normal
3. As soon as you plug your device in, ignore any messages stating the driver did not install and look in device manager for the new device 'S1Boot Fastboot' . Right click this and click 'update driver'. This is the first stage you need to be quick at. As soon as you click this and the update driver window pops up you can relax! You can let go of the volume up button now also, as the device will disconnect in the background anyway! You can also unplug the phone now too.
[NOTE: If windows is still trying to install this device, you won't see update driver until it stops/fails. This is when you have a few seconds to click update driver, so be quick!]
4. Click 'Browse my computer for driver software'
5. Click 'Let me pick from a list of device drivers on my computer'
6. Click next with 'Show All Devices' highlighted
7. Click 'Have disk'
8. Click 'Browse'
9. Go to the the .inf file and open it
10. Click 'ok'
11. You will now have a list of three models. Select 'Android Bootloader Interface'. (It is easy to miss this step out and accidently choose the default model so make sure to select it correctly!)
12. BEFORE you click next, we need to get the phone connection ready again, this is the second stage where quick actions are required.
Disconnect you phone if you already haven't. Connect the phone once more in Fastboot mode. As soon as it is connected click next on the window to install drivers
13. If you followed this right you will have installed drivers before the phone had time to disconnet
14. Now that the drivers are installed for the Xperia S, it will no longer disconnect from fastboot mode and work as it should!

Now contiune to follow Sony's guide

I hope this helps you fellow Xperia S users that have problems!

The solution has already been found and posted. I know you mean well, but use search

For Win7 x64, the Arc drivers are needed otherwise it appears the drivers aren't read properly.

For Arc drivers see last page as the first post isn't updated yet.

Thanks! Was looking for this

Also, for 64bit system, make sure in the android_winusb.inf you have the following entry under [Google.NTamd64].

; SonyEricsson
%SingleAdbInterface% = USB_Install, USB\VID_0FCE&PID_0DDE
%CompositeAdbInterface% = USB_Install, USB\VID_0FCE&PID_0DDE&MI_01
%SingleBootLoaderInterface% = USB_Install, USB\VID_0FCE&PID_0DDE

Apparently some versions of the inf only have that under [Google.NTx86].
You can copy and paste it in the same format as the rest of the entries.

Sorry. I don't need to use search as I already read (and just re-read) this post and still had problems.

And seeing as this is a different solution, and quite detailed for those not too familiar with Windows, it may help.

Even means users can use the files all from the official sites. If users search for this in the future, member posted files may be deleted, like I have found on numerous occasions.

Next time, I'll keep it to myself

No reason not to share it. it is a bit easier to read through than dooms instructions, just don't open threads when it could have been easily put in the existing thread :)

I see

I guess I should have stated, but I couldn't reply to the thread as it is in the dev section and I have less than 10 posts

I would usually help more, but usually with the amount of time I have to browse the forums and after searching, someone already has a solution! I guess this is only a good thing!

Maybe it could be added or linked to if necessary

Thank you footyfanatic:
Do you mind if I translate your solution and I post it in HTCMania? a user of that forum is having problems to install his phone's drivers.

Yes this will be fine

Not work for me..phone continue to disconnect on my eeebox (work percect and bootloader unlock on my main PC) WHY ,_;

On eeebox Win 7 home premium 32 bit

On main Win 7 ultimate 64 bit

EDIT UPDATE

Worked for me if I select Android ADB interface and not Android Bootloader Interface
