Hi Guys,

I'm hoping someone will help me with my Xperia Z2.

I was running generic uk unbranded .55 firmware, previously I had just rooted to backup TA, by mistake I press update to .402 OTA which gave me green android laying down with red triangle.

So decided to flash .402 ftf file to do a clean instal of the firmware, however after it finished flashing, the phone would not switch on, no led flash at all or vibrate tried various combinations.

Power + volume up for 10 seconds and more - no vibrate or screen on

Sim slot pressed red button while holding power button - no vibrate or screen on

Tried plug in in phone while holding volume down - nothing happens but phone pops up on device manager as a unrecognised device

But nothing worked, so I left the phone today when I got back someone in the xperia z2 forum in my thread said to check this thread, I noticed when I plugged the phone to a charger the orange led would come on for a second and then disappear.

This is my log from flashtool when I flashed the .402 ftf file.

Does this mean my battery is flat and it need charging again, I had already left it 12 hours charging before .

Help!

Edit* after reading a few posts i've put a rubber band around the volume down button and the red led is on, but I do not see the phone in device manager.

An nothing is happening with flashtool.

**Edit

Well the pc recognised the device and started installing something, after this finished the phone led went off, and flashtool says phone connected with usb debbuging off.

**edit

Well that didn't work tried to use the rubber band trick came back but nothing changed. have gievn up will send for repairs.

What can I do?

Thanks
