Hey guys i hope someone can help me out : )
Problem:
I froze some system apps on my xperia pro including mtp (the one that you need for the usb to connect to the computer)?!
well then i was using the phone like regularly and it suddenly froze.
Rebooted the phone ..black screen , the phone is booting normally but i cant see a thing of course.
Fastboot / Flash mode
With flashtool It says its connecting but then i get an error
With the cmd fastboot method its just stating "waiting for device" and when i connect it in fastboot mode nothing is happening just windows telling me thats something wrong with the usb connection and it wont work.
When the phone is turned on and connected to the computer i can see it listed in the device manager as mk16i
if that is relevant
Thanks for reading.
problem 1 : is your phone hardware qwerty button light up when you turn it on and dim when wait a few second? if similiar like that maybe you need to replace the flex cable
problem 2 : try reinstall your phone's driver and make sure you connect the phone in fastboot mode with blue notification led light up.

so my phone r800i xperia play i tried to get cm9 aqnd when it told me to fastboot
reboot the device to cwm it didnt turn on and when i press on button it just makes a buzz and it connects to my comp it like 1 min and the red light flickers while its pluged in to my computer using usb then it pops up unkown device plugged in your pc.then fails to install it help fastboot and flash mode wont turn on.
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,

hi ppl
usb not recognize, not even the "unknow device" just like nothing conected. only logo "sonyericson" show. if use hot keys to flash mode or fastboot mode, the phone stay stuck in a blackscreen and a green light or blue light in the power button, depending what condition u start.
used flashtools, and pc companion tryin to fix, but not work if no usb is detected.
I have arc s with running cm11.All the drivers are completely install on my laptop window 8.1.when I swtch to fastboot my arc s doesn't load to fastboot why although I have latest fastboot and adb drivers and latest flashtool too.when ever I try to load to fastboot or flashboot blue led blinks for just 0.2 sec and mobile goes to charging plzzz help me to get rid of this.When i used flashtool n check the option of drivers in flashtool,flashtool says list of adb devices CX... And list of fastboot devices none.When i switch off the phone and turn it to fastboot blue led once again blinks for just 0.2s plzzz help pllzzzzzzz
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
Hello everyone,
I really hope somebody can help me with this.
I have xperia z5 premium, power button stopped working a month ago or something, but the phone was working perfectly fine. Of course, I made a mistake and did not charge it in time and it turned off. Now I can't get it to turn back on because the button is not working.
I explored all my options and I realized I can do fastboot reboot through fastboot and adb. However, I can't seem to get my phone to go into fastboot mode.
I hold volume up button (which I know for a fact is working), I plugin usb, and instead of getting that blue led light everybody keeps talking about, I just get a red led and then a green one after the sony logo that signals the phone is charging.
I installed ADB and xperia z5 premium drivers and I still can't get it to work. When I type fastboot reboot it says <waiting for device> when I try adb reboot or adb reboot bootloader it says "error: device not found".
I've also installed xperia companion app and when I plugin my phone it shows a screen where it says: "Your device is locked
1. Unlock require
Unlock the device using password or fingerpint if needed
2. Allow data access
On your device, select the option to allow data access"
I've tried doing the same thing with adb on two different pcs, always get the same result. Phone just gets to charging screen and keeps charging instead of going into any mode.
I also tried holding volume down button and plugging in usb which is supposed to be recovery mode or something, but that doesnt work either, I also get charging screen. And I'm 100% sure both my volume up and volume down buttons are working.
What am I doing wrong?
P.S - Debugging mode is not on, im 100% sure since i never turned it on.
Somebody please help!
Thanks!
