Do just that :- Step By Step
- open device manager
- connect in fastboot mode and click the s1 boot fastboot right away
- disconnect the device , without closing the s1boot fastboot windows !
- click update drivers -> browse for drivers on my computer -> let me pick from a list of device drivers on my computer
-> have disk -> browse and locate the device drivers -> press ok
- reconnect the device in fastboot and click next on the computer right away of the blue led

hello bro it says it encountered an error, the android ADB something bro

I think you dont need to disconnect the phone...
Open Device Manager in your windows, standby at that....Turn off your phone, and after it turned off, push and hold the Volume Up button and at the same time connect the phone to the computer with a USB-cable. This will trigger FASTBOOT mode and windows will start driver search....
Once there is a popup in Device Manager with what word i cant remember, directly right click on it and point to the folder containing the driver...If the folder youre having, failed to give the driver required....Download driver below, my driver compilation...
http://www.mediafire.com/?dw77ineguikk7bo
Unzip the Xperia_Ion_Fastboot_USBDriver.rar and unzip both files that came out
that is fastboot_with_Android_USB_file.rar and drivers.zip
Point out the driver search to drivers.zip folder...Hope it helps

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!

How the hell do I get a custom ROM on this thing?

I'm trying to unlock bootloader, root, and install custom rom.
OK, problems I have:
Tried to unlock bootloader, but cannot get phone to connect to pc in Fastboot mode. I think its something to do with the driver. Ive tried selecting all the different s1001 s1002 etc but none work.
Tried to used flashtool but it says 'Device connected with USB debugging off'. USB debugging is definately on!
Tried to root, only found zerg rush that will not work at my buld is .78. Cant find any guide that dont require me to be on a lower version!
I have been searching and looking since 16:00, its now 20:00 and im no closer. Please help
I see this thread:
http://forum.xda-developers.com/showthread.php?t=1662199
It mentions:
'your computer should prompt you to install drivers for the new device if it does then select 'install manually' and browse to the location of the drivers'
Where is the location of these drivers?
When i press search and insert usb, i get a message 'USB device not recognised'
I have a 'S1Boot fastboot' in Device Manager. What drivers will work?
I opened flastool, and connected my phone pressing 'back' and selected r800i and i got the message 'Your phone bootloader cannot be officially unlocked'. I have checked and on the phone it definately says my boot loader can be unlocked. Why did i get the error?
Ive gone to flashtool/drivers and opened Flashtool-drivers.exe, when i tried to install the r800 driveres and it comes up with 'Instal Failed'
Seems Win 8 wasnt letting me install drivers: follow these instructions:
I have done these steps and It worked for me.
Please hit thanks button / say thanks if it worked for you.
To get started:
From the Metro Start Screen or Desktop, open Settings (move your mouse to the bottom-right-corner of the screen and wait for the pop-out bar to appear, then click the Gear icon).
Click ‘More PC Settings’.
Click ‘General’.
Scroll down, and click ‘Restart now’ under ‘Advanced startup’.
Wait a bit.
Click ‘Troubleshoot’.
Click ‘Advanced Options’
Click ‘Windows Startup Settings’
Click Restart.
Choose option 7 (Disable Driver signature Enforcement)
Profit!
Now you can install the drivers of fastboot.
And now you can connect your phone in fastboot.
NOTE: It will be back enabled when you restart, but you only have to do this to install the drivers.
I didn't installed the android SDK !!
Thanks to milowke
Hmmm, done this and installed drivers, but when i connect my phone it STILL says 'USB device not recognised'!
I gave up and used a windows 7 machine

if drivers are not installed properly.. Start Windows 7 or 8 or 8.1 in "Disabled Driver Sginature Mode" (Google this if you don't know how)
if you think drivers are installed correctly.. then do one think cuz I also face the same issue.. Don't connect the Device and then try to FLash by the electric signal..
first select the firmware .. click ok.. then let the software tell u.. to connect the Device.. do that and it should work !! let us know.
Drivers are "SEMC Flash Device" for "S1Boot Fastboot". And when i try to load kernel first when device is disabled it gives me this.

Emma software from Sony works well for recovery my phone to original ROM and Kernel.
Maybe "back" button is stuck. Can you boot into android (doesn't matter is it custom rom or official firmware)
Also, try different usb port or different usb cable
Untill you found a solution you can flash custom kernels in .ftf format (you can flash them in flash mode)

Problem is not in phone but in Flashtool. If I have flash mode on phone devices shows me "S1Boot Flashmode" when fastboot "S1Boot Fastboot". I tryied all usb ports on my PC and 4 USB Cables (1 Original from XPlay and 3 others from different samsung phones) and Yea I can boot into android, and i tryied flash custom kernels in .ftf format but its always brick my phone and I must use Emma software for Revive the phone .

Yeah, it looks like phone is ok
Try to uninsatll all related drivers from PC (go to device manager, righ-click on driver, then "uninstall"). Do it when for all 3 modes (flash, normal and fastboot mode)
Then disconnect and connect phone again.
Or choose to manually install drivers for
Or reinstall flashtool

Unable to get xA2 in fastboot mode

Hi there,
strugggling to get the xa2 into fastboot mode so I can flash a new boot.img and root. I've enabled OEM unlocking and installed the USB drivers. the command 'adb reboot fastboot' doesn't work, just reboots the phone. adb over usb works fine. The official method to get into fastboot 'plug in USB whilst holding vol up/down' also doesnt allow me to get itno fastboot mode, phone just stays blank with a notification LED. I use 'fastboot devices' to see it if it connected. I've tried this on 2 PCs now to no avail
I'm thinking maybe the fastboot drivers are wrong?
Does anyone have any other suggestions or help?
Thanks

Hi thanks for getting back to me,
I assume you meant the '15 second installer', which I just did just install successfully. I am still unable to see the device with 'fastboot devices' command.
Other info: I have factory reset the phone, made sure oem unlock is checked, tried the same process on another computer. I can get adb mode to work fine, but the command 'adb reboot fastboot' just reboots the phone as usual

That is the correct behaviour.
Blue LED = Fastboot mode
Green LED = Flash mode (for reflashing stock firmware with XperiFirm in case EVERYTHING is broken)
Install these drivers:
https://adb.clockworkmod.com/
When in Fastboot mode, go to device manager, there is an Android device in there (may also be called MTP device).
In the device manager, install a new driver for that and use the ADB driver from C:\Program Files (x86)\ClockworkMod\Universal ADB Driver
Windows will tell you that it's the wrong driver. Install it anyway and Fastboot will recognize your XA2 now.

If it won't work, after that just go to devices and printers and delete Xperia XA2. It will work.
Else, after installing 15 seconds, inside device manager, update the driver of your phone (or mtp device), select local, then Android device, then fastboot. Disconnect the phone and reconnect as before (volume down)
Fastboot is VOL. UP (on this device)! (Not vol. down)
So basically turn off the device, hold Vol. UP and simply connect to USB, hold Vol. UP until LED is steady blue and you are set.
Note: VOLUME UP activates fastboot and VOLUME DOWN enables flashmode and/or recovery mode
Similar trouble here.
1. VOL UP + plug in USB: Blue led blinks once, then phone shows it's charging (turned off)
2. adb reboot bootloader: Phone just turns off

I had the same issue with my XA2.
The solution (at least for me) was: different USB cable and different USB-port. As it turns out, my cable was somehow worn out (though data transfer and charging was working quite well). Going into fastboot, the blue led lit very short time and then the phone restarted. Furthermore on my PC it somehow only worked on the one USB port and not the other (both USB 3.0).
--> Maybe trying the most obvious might help also some of you

Did solve this by connecting to different PC. No cable/port/hub change did help. Looks like there was some trouble with drivers (though the same PC fastboots Z3 Tablet Compact perfectly).

I'm also having the same issue with my Xperia XA2 Ultra. (boy that's a mouthful)
Phone model is H3223.
Host OS is Windows 10 Pro v. 2004.
Using latest Android SDK tools (i.e. ADB and Fastboot platform tools): platform-tools_r30.0.5-windows. Got it directly from Android site.
I think I had a previous driver for Android already installed or somehow Windows got it. ADB worked, Fastboot didn't. Read online about someone on this forum getting it to work by using XZ2 driver from Sony as they evidently don't have a published driver for this device. The person who posted this solution had reported problems with this driver recently. I tried it anyway.... ADB commands work and my phone shows up when listing devices. Reboot into fastboot mode and the only thing my phone does is show a blue light indicator... no splash screen or logo. To me this means it's starting fastboot but my driver isn't working with it to recognize it as any commands for fastboot return nothing or fail. It doesn't show up under fastboot devices command.
Does anyone have a clue as to what to do?

I have the exact same problem, have not managed to find a solution trying with 3(!) different laptops and 2 different cables. No idea what could go wrong. I checked the device and it says that unlocking is okay. Really frustrating.
Edit: I actually found a way! Once you manage to enter the fastboot mode (light is permanently blue) go to the device manager in windows, click on the unknown android device, and install custom drivers (either by selecting from the list or by picking the universal adb driers from a local folder). These custom drivers should be adb drivers. Once they are installed, fastboot should work.
I had the same problems with my device XA2 H3113 and Win10.
My solution: Try it with Ubuntu. Just grab an 8GB usbstick, install Ubuntu via usb-installer, boot ubuntu and open a terminal
sudo apt update
sudo apt install adb fastboot

(2) Install it with "Y" confirmation for all 3 options and reboot the PC
(3) Disable the internet connection of your pc
(4) Reboot your phone to fastboot mode and plug it to your PC's USB 2.0 port (important)
(5) Open device manager on PC and scan for hardware changes from the option if your device is not listed already
(6) If it shows 'Asus android device' -> "ASUS Android Bootloader Interface', right click on it and uninstall device with the 'delete the driver software' option ticked.

Hello, I followed your mentioned steps but in my drivers its showing "Samsung Android Device" is that okay for my asus zenfone max pro m1 device? Or there is one portable device option, is that it?
Hi guys, specially opened an account because of this issue. I am unable to run the fastboot devices command even after following all the aforementioned steps. Phone screen turns black and a message appears on the top left stating "press any key to shutdown", while the fastboot devices command gives a "??????? fastboot" response on my PC. PLEASE HELP!

After I completed all the steps, my phone showed on screen "press any key to shutdown" and even in device manager it shows android ADB interface as hidden. Help please. Rebooting again to fastboot mode doesn't help because it shows the same screen "press any key to shutdown" on reconnecting with PC.
May Asus x01bd can't in to the mode fastboot..how to solved it?

Well i learned this from somewhere but actually you need to turn off the secure boot in your PC from the BIOS. That's what helped me do it

Well you know how there's a BIOS in your PC which contains the basic commands required to run a computer. There is a setting called secure boot inside your BIOS. You need to turn it off and then install fastboot tools. To open the BIOS, repeatedly press F10 or F8 on your computer while it is opening. This is how it worked for me atleast
