[Q] Xperia Arc debug mode not working?

Hi,
I just tried to setup the Arc as debug device, but it doesn't seem to work.
May app is declared "debuggable" (I already tested it on an LG Optimus Speed) and the "USB Debugging" option on my Arc is turned on.
I also did install the driver from here.
Now, if I connect the Phone with my PC (running Windows XP), it shows up in the connected hardware section as "Sony Ericsson sa0102 ADB Interface Driver" and my phone tells me it's "connected for USB-debugging".
However, I can't find it, not with "adb devices" nor with Eclipse > "run on target" option.
Has anyone got this working so far?
Kind regards,
cherryfish
Edit: maybe someone can move this to the developer forum, I can't post there yet.

install and reboot
After installing the special device driver you mentioned, installing the SE packs from the “SDK Manager” and rebooting the PC it worked.
But it put down SE even further down the line of potential next devices. So much unnecessary hassle.

Hi,
I should have come back to this thread...
My mistake actually was that I tried to do it the complicated way. What worked for me on more than one PC (Win 7, Win XP) later was:
- just plug in Xperia Arc via USB (debug mode turned on)
- wait (for the auto-install)
- happily see it working
Do I understand your post correctly that this didn't work for you?
Actually I was quite impressed how fluent and easy this was. I did the same procedure with an LG Optimus Speed and THAT was a hassle...!
Kind regards,
cherryfish

R800i Issues with USB Driver and Bootloader!

Hi Guys,
Any help would be great! i do have google talk if anyone is willing to help me out!
My R800i Is rooted and has a version of recovery but not sure which version, i am wanting to update my phone with a better kernel and rom since the current one i have installed is giving me issues ( not being able to receive incoming calls for example )
Another problem is i reformatted the phone since i was having issues with receiving calls but now when i connect my phone to ANY computer via the USB cable the computer trys to install MTP or MSC driver ( depends on which connection type i select ) the Installer fails and i cant even take any files off my phone.
Provided details below. i want to somehow get into the current bootloader and install the ROM thats on my SD card! i do have flashtool installed and Android tool SDK installed but still no success in phone wanting to talk to my laptop.
I am running windows 7 64 bit. i am starting to think the phone is belond repair since i cant get any software to work between the phone and computer.
does anyone know what buttons i need to push on the Xperia Play to enter into the boot loader, i have tried pressing the back button and search button on phone boot but nothing happens apart from the phone starts up normally.
would a factory reset delete the boot loader and other config-ed software off the phone is this why i cant enter the boot loader or am i not pressing the right buttons on boot.
Any help would be really appreciated!

If you want to change the kernel you must unlock your bootloader. If your Xperia Play is a SIM free one, you can do it for free in this link: http://unlockbootloader.sonymobile.com
For SIM locked devices I think you must find another ways to do it. There are some online sites that unlock bootloader to SIM locked devices for a fee.
Once you have unlocked your bootloader, turn off the phone, hold on the search button, plug the USB cable in the computer, release the search button (power button LED will be blue) and install this driver: http://drivers.softpedia.com/progDownload/Google-USB-Driver-Revision4-Download-139077.html
Now you are ready to flash any kernel you want with Flashtool or any other app.

Thanks for the information, i have already done this, i payed £25 for a guy on this forum to unlock my phone to any network. i'll give this a try and get back to you, problem is the phone doesn't like to talk to my laptop via USB cable keeps on failing to install the drivers..
Thanks for quick response.

I have tried what you said but having problems with connecting my phone to my Windows 7 Laptop!

Check your device manager. The fastest way to open it is running this command: devmgmt.msc
There must be some kind of Android device while your phone is connected in fastboot mode. If you see it, update its driver with the Google USB driver v4 pointing at the folder path with the uncompressed files.

Hi I tried what you said, i Turned off my phone and holded the search button and turned it back on, the light went blue and the computer popped up trying to install fast boot i point to the SDK folder to update the driver but it fails.
do you have google talk might be easier on there to talk! cheers!

I'm not using gtalk atm. Sorry.
Be sure the driver you downloaded is named usb_driver_rev4.zip: http://drivers.softpedia.com/dyn-postdownload.php?p=139077&t=4&i=1
If Windows doesn't detects any driver in that uncompressed folder, you can choose to select the device from a list, point to that folder and force to install the driver. It's named something like Android ADB Interface.

Thanks for the download link, i going to try this in a bit and get back to you! thanks for the support guys! :good:

Just tried, i put my phone into Media Transfer Mode.. my computer tried to install the MTP usb device and i directed the installation to the driver you linked..
Update Driver Software says: the best driver software for your device is already installed MTP USB DEVICE, there is a small yellow triangle on the icon and in MTP USB Device Properties it says: This device cannot start. (Code 10)
i need someone to Teamviewer with me, for the record i don't have the Sony Ericsson software installed on my Computer because that still wont install the drivers for my phone, i also know its not needed for installing new kernel and roms.
i tried connecting this phone to a bunch of pcs including my friends and it still fails to install any drivers!!! i think i am just going to bin this phone! i have had enough (

You must install that driver when you plug the phone in fastboot mode. It shouldn't work in any other case. In other words, when you plug your Xperia Play being powered on and Android is running it needs one driver, and when you boot it in fastboot mode you need other driver.
Please, install the driver following the steps previously posted with your phone in fastboot mode (blue LED).

Hello, i put my phone into fastboot mode, my device manager shows 1 device not installed S1Boot Fastboot, i right click go to properties and click update driver...
then i browse my computer for driver software i point the location to usb_driver_rev4\usb_driver and it says: Windows was unable to install your s1Boot fastboot!

Ok, let's see...
Try to update the driver using the "choose from a list" option to force the installation, point to the driver folder and select "Android ADB Interface" from the list. If Windows shows a warning message don't worry about it and go ahead.

i tryed this and its not wanting to work (

Sorry to hear that because I don't have any more ideas for your problem.
Maybe you may spend some minutes searching in the forum to find some detail that can help you.

i need someone with teamviewer to help me go though the setup process again, if anyone is willing to get my phone working i will happy pay them some money!
Thanks Jcarbox for all your support!
Regards
Paul

I just check the Windows device manager with my phone plugged in bootloader mode and it appears as Android Bootloader Interface, so this is the device you must choose from the list when you install the driver.
Hope this helps you.

thanks for the help, to bad my phone isnt having any of it.. just going to buy another phone (

This may work

hi PsychoShaft,
I had similar problems. I don't know how to fix it permanently. but i do this to make it work for some time.First, download flashtool and install it.Open your device manager and select view->show hidden drivers.Then, delete all your drivers related to xperia play. like the adb interface, semc flash ,etc. All of them in all categories. then reboot your computer into safe mode with administrator and connect your device with flashtool running in your windows in safe mode. then the flashtool will indicate that you don't have the drivers. then,open the drivers folder in flashtool and use the setup to install arc-play-...,flashmode drivers and fastboot mode drivers.then after the installation is over windows will ask you to reboot.now reboot with your mobile connected. after boot windows will automatically install the drivers. then unplug your phone and turn off it and connect in flash/fastboot mode.it will automatically install drivers.wait for windows to say drivers installed successfully or installation failed. don't unplug it in the middle of the process then you will have to start from first.sometimes it will not work in the first time ,then reboot into safe mode and try again installing the drivers and rebooting into safe mode itself and connecting your device.at one point of time flashtool will say your device is connected in flas/fastboot mode.then continue with flashing
Gladwin.

Thanks for the support guys i managed to solve the issue!

Try!
01 - If the Device shows Sony Screen when booting and the booting animation but DOESN'T fully BOOT
Run Sony Companion (Google it if you haven't got it)
Click on Support Zone
Then look for "phone software update" --> click start
then click repair

you have possibly hard bricked your Device and may need to purchase new device
i had a similar problem with my Xperia S , my phone had crashed and the SD card was unavailable , i had to Folow "Step One" to fix it , lost all my apps , but i got access to my SD card back. also most apps had to "Force Stop" because they were not working it was very annoying
I hope this helps , and i am sorry for any mistakes. english isnt my primary and im still unsure about some things

XPERIA S problems connecting to PC

Having lost my XPERIA Arc S recently, the insurance company kindly sent me a replacement handset (as they do). The only problem was that the replacement wasn't an Arc S but an XPERIA S.
There I was for a minute thinking I had hit the jackpot and received a better handset only to encounter the PC connection issues experienced by so many others with this phone.
The phone I received: stock XPERIA S, not rooted, running Android 4.1.2 (build 6.2.B.0.200).
Shock, shock, horror, horror, shock, shock, horror you know the song
Nevertheless, being stubborn in nature, I kept trying to find a solution to the issue and started re-installing drivers, software, switching off firewalls, activating USB Debugging, etc ... everything I read about in other posts but alas, all to no avail.
Then I stumbled upon something strange, namely that when I selected the option:
"Settings" -> "Xperia" -> "USB Connectivity" -> "Install PC Companion"
two (2) drives mounted on my Windows 7 system:
Code:
1. (D:) Sony PC Software
2. [XPERIA S
Note: Developer Options, WiFi, Bluetooth, NFC and Screen Lock were all OFF for this to work. Mobile Data was ON.
Forgive me that I am unable to provide you with further information and/or an explanation.
My coding knowledge and experience = 1/10; My stubbornness knowledge and experience = 9/10
It would be good if someone could be so kind to investigate and explain.
If you're in a similar position perhaps this method may work for you (please hit the "Thanks" button if that's the case)
P.S. Have tested this in Linux Mint "Maya" but nothing ... don't know about other distros or Macintosh.

Normally you plug and it mount as portable media in PC. Perhaps try in Windows.

Thanks for your reply xminirom.
If only it behaved normally xminirom, I would never have posted this thread :laugh: Perhaps it's worth noting that this method only worked in Windows 7 not Linux Mint.
Update: Have also tested this method in Windows XP and worked just like in Windows 7.
Will be testing if the same applies to Windows 8 and perhaps even in some other Linux distros. Perhaps it's worth saying that when it comes to Linux, I have followed every step of Lloir's guide on setting up MTP in Linux without any luck ... perhaps I ought to try with Android SDK installed come to think of it
Sorry but I don't have access to a Mac (and have no intention of having access to a Mac ... no offence meant by saying I'm not a fan of Apple)

1- the phone has an installer package for the software PC Companion, setup to run when the phone is plugged in to a computer. It acts like a software installer CD-ROM being inserted into the PC.
when you first plug the phone into a PC, your phone should ask you if you want to install PC companion. It also gives the option to never ask to install again.
I would say that "1. (D Sony PC Software" is being reported like a separate partition of the onboard SD card. Using a root explorer, you should be able to find the install file and delete it (I always delete it just for the space). Deleting it should remove this entry.
2- The entry "2. XPERIA S" will be the SD card mounted in MTP mode. If you have USB Debugging selected you should get MSC mode for the card (thats how it works on my ION)

The good news is that you really did get a better handset

Thanks for this Toledo_JAB. Although I didn't really need an explanation of how the process of mounting works, you're not a mind reader so I will try and be a bit more descriptive.
The problem is: device will not automatically mount when connected to a PC using a data cable, unlike my Xperia Arc S which mounts as soon as the cable is connected and is recognised as a phone (giving me access to the memory card and system when connected in MTP mode and only access to the memory card when connected in MSC mode). Have tried on several PC's now and it just won't connect when you plug it in. Initially I suspected it's Windows 7 causing the problem, so connected to a machine running Linux Mint Maya, another machine running Windows XP, yet another machine running Windows 7, and another machine running Windows Vista and finally last night another machine running Windows 8 Pro. The phone refuses to connect automatically to any PC running Linux Mint Maya, Windows XP, Vista, 7 and 8. Since it cannot connect to any PC as it normally should, I can't use the "Repair Phone" option using Sony's PC Companion to possibly repair the problem.
It's worth noting that the XPERIA S does not have a memory card slot (due to integrated storage), and therefore I couldn't just load a Stock ROM and install it from the memory card as I was able to do with my Arc S when it became unresponsive some time ago.
Having Googled my problem, I found from other posts (in this forum) and other forums that the XPERIA S and XPERIA Z are known for this problem and various solutions are suggested. However, not one of those solutions actually helped me and my XPERIA S just refuses to connect to a PC even with USB Debugging selected (MSC for the memory card doesn't even come up).
The XPERIA S I have only connects to a machines running Windows when the "Install PC Companion" option is selected. This is it: there is no other way to connect it to a PC. Furthermore, the conditions in my first post need to be met in order for this to work (various functions turned ON and others turned OFF).
It seems that nobody else has come across such behaviour or if they have, then they haven't shared it with the world, and it is this very behaviour I have found strange and couldn't understand/explain/find logic in. Hoping that someone could provide a logical explanation as why the phone behaves in such a way and only connecting to a PC under such conditions (see my first post).
Update: Since the first post, I have downloaded Flashtool by Bin4ry in the hope of creating a memory dump and/or back up of the installed ROM later today to help someone understand/explain why this particular XPERIA S refuses to connect to a computer in any other way than when the "Install PC Companion" option is selected.
Hopefully I am making sense this time and not confusing everyone again
Thanks again for all your replies people

To much info is better than to Little
Have you tried to reinstall PC companion and flashtool drivers?
For flashtool drivers I always just install all of them.

You can find the drivers in Flashtool's DRIVERS folder.

[Q] Xperia Z1 Compact on Windows 7 64bit

Tried to connect my phone to a Windows 7 64bit PC using the USB cable but Windows couldn't find the device driver for D5503. I found these from the Sony site and downloaded them but I couldn't install them manually either. Anyone managed to gracefully connect this to a PC?

I have a Win7 64Bit System. I have not yet tested on Win8.1 64bit, but will do in the next days.
"Through Update" means, that my (already installed) PC Companion had informed me for an updated version 1-2 weeks ago and I've installed it.
So last Friday I just plugged the Z1C and it the driver was installed and I was able to use my phone on the computer.
If you installed the PC Companion after you connected your phone, than you might have to remove the device within the device manager. After a reboot it should work. At least my experience with other Sony devices.

just bought a xperia z1 compact, plugged into PC, didn't work.
found this thread, installed PC companion etc... still doesn't work. Windows 7 64bit just shows it with a yellow triangle in the device manager?!
I try to connect through PC companion and it does nothing, just sits there.
Please help!?:good:

Please read... It says that they manage to solve the issue by installing Windows Media Player.

I read that. But I have windows media player installed. Who doesn't on a Windows pc, its default?

I have it working on laptop, will give up with the PC.

Same problems as described above.
Following worked for my PC: (I have a Dutch windows (7, 64) and translated the following commands in English. So it is possible that these commands are named different in the English windows version.)
Go to device manager, right click on D5503 (with the yellow triangle), Search for device on my computer (second option), I want to choose from the driver list on my computer, uncheck view compatible hardware, standard MTP device, MTP USB device.
The Phone has to be set on MTP in the USB connection setting to use it with PC companion

Same issue here, any ideas?
USB debugging and MTP already worked successful, but now it's not working anymore.
Following situation:
If I disable USB debugging and plug USB cable into PC then nothing is shown in Windows Explorer and even not in the device manager. The field "MTP" is greyed out/disabled in XPERIA connectivity -> USB connection.
If I enable USB debugging, phone says "connected" however Windows is showing yellow triangle. I tried to download the drivers from http://developer.sonymobile.com/downloads/drivers/xperia-z1-compact-driver/ but Windows doesn't detect them.
If I try to uninstall the drivers right click on D5503 (with yellow triangle) nothing happens.
Phone reset the only idea?

Ok, I got it.
Just added the following lines to android_winusb.inf:

Hi there, I'm having the same problem. I've installed the CWM recovery, but stupidly didn't check that I could access the phone over USB beforehand. Now I'm stuck with a continuously rebooting phone, and windows says it can't install the Sony driver.
When you said you added the above two lines to the android_winusb.inf file, what did you mean? I found this file in the
C:\Windows\System32\DriverStore\FileRepository\android_winusb.inf_amd64_neutral_d58a98da913cec3a
folder, but couldn't edit it, even as admin.
Any help appreciated, thanks.

Ok, I installed the driver on a notebook and was able to get a ROM (CM 11 M8 snapshot) loaded to /sdcard. But after I installed from zip, I'm still stuck in a boot loop to CWM recovery.
Anyone know how to get out of this?

If you can install PC Companion then it should be fine, the correct z1c driver will be installed for your windows and Adb will work normally. But just some people never can install PCC successfully and they will need to modify their android_winusb.inf to add two lines and let your windows to recognize your Z1c.

Alternative way is to install Xperia driver set but I have never tried this method.

If you stuck in a boot loop with wrong recovery(I just tried it today). I'm afraid you have to flash a .ftf and clean all things out. At first, you can try to boot into fastboot mode(you will need to make sure your adb works) and try to flash other custom recovery and wish no boot loop again.

If it doesn't work too, then you have to start from scratch for your phone. Please follow my guide step5 to step16.

I went back to the previous snapshot, and that worked. Phone is up and running now.
Having said that, I'm sure I'll get myself into a mess like this again, so your links will be very useful!
Thanks.
