i asked my cousin who worked with these problems he says you have to do some complex thing on your computer. Any other way i might send it to sony.
it keeps poping up that it cannot recognize my usb plugged in .
Try downloading and running the update service:

This should flash your phone back to default (stock) ROM I believe. It worked for me when I deleted /system
Flashtool is much better that SEUS in my opinion. Much more flexible.
When my Play would be rebooting constantly I:
1. Connected it to pc, Let it recognize my device
2. Before it would reboot again, I took the battery out.
3. Entered fastboot mode
4. Flashed new firmware
Hi,
I can't get into fastboot mode on my Sony Acro S. I hold the volume up button and then insert the USB cable. The blue led light up and everything seams to be ok but after some seconds the led get dark and the phone shows the Sony logo. The computer recognize the phone and the device manager shows an unknown device but It disapear after a while...
Anyone that have seen this before and maybe have a solution?

That means your computers system is unable to install essential fastboot drivers for your phone. Try alternative USB ports.
If still it doesn't work then try it on another system. Also have a look on this,

I have exactly the same problem. Can't get my device to go into any modes - flashmode or fastboot mode. have my device turned off, hold down the back (or menu) button, and finally connect the USB. The green LED flashes for less than 0.5s and then continues to charge mode with battery icon. I want to refresh the firmware in my phone using PC companion (the latest version) but when asked to put the device into flashmode the PC doesn't detect it. PC companion has installed all the correct USB drivers on my computer. Anyone knows how to solve this problem?
Thanks
I have an xperia xa1 and when I connect it to flashtool I throw an error and it caused my cell phone not to turn on, it does not load, it does not enter in any way and when I connect it to the computer it does not recognize it, when I connect it to the load only turn on the red LED, but the animation of the load does not appear if someone has some solution I would appreciate it too. :crying: :crying:
hi, ive tried to root my xperia xa1 ultra, but it failed after flash boot.img and recovery.img with flashtool.
if i power on without cable, freezes on sony logo with white background, and i have to wait until the battery is empty.
with charger, freeze in sony logo but if i unplug the cable the phone power off.
if i start the phone with cable connected on pc, in FLASHMODE, at 30+- seconds PHONE REBOOT IN FLASHMODE AND LOOP.
bootloader is unlocked.
i cant know what % of battery the phone have, but i think it charges while stuck on sony logo while is connected at the carger(no pc), and then i can unplug and the phone shutdown, and didnt have to wait ALL NIGHT to the battery empty.
so the questions,
is bricked? do i have a solution? how can i undo the failed root process and have the old recovery? remember that i have the loop with flashmode
ps: ive tried to reboot into recovery mode with adb commands but the phone is not recognized in adb devices, and i dont know if this is a possible solution
thanks you all, sorry for very bad english, please help me!!
