Can't put device into flashmode or fastboot mode.

kp789 — Thu, 13 Jun 2013 17:39:28 GMT

Hi,

I can't get my device to go into any modes - flashmode or fastboot mode. I 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. Does anybody have any idea why the phone won't let me enter these other modes?

Thanks

Ok thanks.

Have tried that and the phone still goes into charging mode while pressing the back key and connecting the USB connector. SUS doesn't pick up the phone to do the update.

Sequence of operation is

disconnect phone from USB

turn off phone for 30s

Plug USB cable into computer

press the back key

plug USB cable into phone

....and it's meant to enter flash mode

mine displays Sony Logo and then the battery icon still.

I think something in the bootload is corrupt or not working properly.

I downloaded the latest JAVA release and have tried to reflash on a windows 7 and a windows xp machine. Neither OS works.

that's odd, and you followed my advise (disable your firewall and antivirus)?

Yeah. I disabled both the firewall and the antivirus software and still no joy. I've even tried to reboot the device into fastboot mode by issuing command using the ADB drivers and flashtool but not still the same. Not sure why I can't even get into flashmode either.

Even I got the same errors.

This is what I did.

Switch off the XPS.

Hold power up+power button till 3 vibrations.

Then tried fastboot/flashtool mode

Worked like a charm!!! :smileysmileythumbsup:

Good Evening/Hello/Hi ,

I have a problem with my Sony Xperia M Dual(C2004). After i flashed my phone does not work perfectly (errors with some application in sd card) and i decided to restore it to stock firmware. The firmware i am trying to use was already flashed other time and it work fine. But now, when i try to get into flashmode the green led light up for 1 second, then light off and stuck into flashmode. I have all drivers on my pc and it recognize the phone as SOMC flash device, but the green led is down and Flashtool not start flashing.... What can I do? Fastboot and recovery mode works fine.

Hi there, I have a solution, use a MACBOOK.

You turn on USB debugging, OEM unlock too in developer settings.

Turn off your phone completely

At the same time as holding the volume up plug in your phone to the MAC and the blue light should appear.

hey Presto 🎊

I realize this post is from 2013, but I had this same problem with a xperia xz with flashtool in 2018. Turns out, for me at least, the solution was mind-numbingly easy. When your device is making the 0.5 second green lights, it is in flashmode. It was just a matter of entering flashmode prior to starting the flash in flashtool, as the application would not reconize a device in flashmode if started when promted by the application.
