Press and hold Volume Up, then plug the USB cable, your screen should enter the recovery mode. CMIIW.

Can you help me?

If you bricked your phone which is very hard to do you`re fu**.
Only way to bring it back is with Jtag and i don`t think riff jtag can do this job.
Just pray and search a jtag in your area !

the drivers installed correctly ?

Just try it at another computer or install a second and if possible different version of Windows. Then there install drivers and follow guid again. I also had problems under Windows XP already. Then tried it at the same PC, but Windows 7 64 bit and suddenly it worked like a charm I always have dual boot, just in case something doesnt work I play around much with my installations
Easiest way is try it at another PC, idk, maybe a friend's or maybe u have a second one.
Already tried to disable Lg Modem?

[Q] Z1 won't turn on

Well i've got this problem with a Xperia Z1 from a friend of mine. It's not powering on. If i press the power button the phone won't turn on. It can enter fastboot but that is everything. The phone is fully charged because that's the only thing that works so far beside the fastboot. It's on stock firmware no custom ROM. Maybe that you people of XDA have the solution i hope so or experienced the same problem and that it is fixable.
Greetings,
Kyrindia

I Had a similar issue, my volume up button got stuck, causing it to always boot in fastboot.
Power up phone, connect to pc, install driver, then run fastboot on your pc and run:
Code:
fastboot continue
Let me know if it helps!

Did something happen to the phone?
Like dropped it in some liquid other than water?
Does the camera button still function?
For an android reinstall:
Boot the phone normally and perform a software reinstall using Sony PC Companion, connect it via USB to your pc.
With PCC you can fully reinstall the software on the phone.

The phone screen was replaced recently. The camera button works fine. And i don't know if there was any other liquid then water in the phone or something like that. The last thing that i could try is to reinstall the software and hopefully that works.
Thanks anyway :good:

Hello there,
I have the same or similar problem, where my P7 won't boot at all, won't go into recovery mode or fast boot mode.
Only thing it does when i have it connected on the charger and try to boot it is flash the LED 4 times red color, then once green, it keeps doing that and that's all it does. i tried what you said and it won't work or boot, it does the same thing.
Your help would be appreciated.

No, it doesn't, however when i connect it to the PC, the PC emits the USB sound (that you've plugged something in) but it doesn't identify or recognize anything.

then there's no way to flash anything to it, the only way is by fastboot and adb commands

That means it's probably a hardware issue? the motherboard might be fried?

P9 Hard Bricked - No recovery, no fastboot

Hi,
First i'm sorry for my bad english.
I've a P9, and i tried to update to Nougat. But something went wrong, and now, i can't boot my phone, no recovery no fastboot. When i plug it on my pc, my phone is recognize as "USB SER". How to unbricked ?
Hold volume down + power for 15 seconds, hold it even longer to try to get into fastboot mode. Was the battery low? Maybe you need to charge the phone up.
My phone is charged.
I tried your solution, but didn't work..

Hey mate, did you find a solution, same thing happened to me ... the only thing I get from the phone is "USB SER" ... never unlocked, rooted or flashed my phone. Could be a hardware failure?
