[Xperia Z3 Compact Q&A, Help & Troubleshooting] bigode69:
Hello guys

I sold a Z3C to a customer but 1 week after the phone died (January V4.4.4). He don't make nothing (root, unlock bootloader, flash rom, etc). Just a sudden death.

The issues were:

-By pressing the power button, the sony logo turned on but suddenly it shuts down just after that (once time).

-When I putted it on chage in the wall it appears the battery level ans it charges as well.

-When I was pressed vol up (or down, i can't remember well) + power it gave 3 vibrations.

- The LED light apperently was working.

What I've tried:

-Recover through the official softaware but I can't because it don't apear in USB and It asked to turn on the phone (the phone don't boot).

-Using flashtool. Same trouble, the usb don't recongnize.

After that, I gave up and sent it to sony repair. So it takes long

SIX months

. In the first, they said that was the battery. Next was the mainboard and that's it, no way to repair and them return the phone to me.

New issues (after the "sony repair"):

- The back glass was badly adjusted. No glue at all.

-No Sony logo anymore when press power button neither the LED lights.

-Good bye the 3 vibrations when press the 2 buttons.

-No charging battery icon when I puted in the wall charge (thank you sony).

-When I put it in the wall charge (or USB cable PC) the LED bright red and the logo sony appears over and over again in an eternal loop. Turns on, turns off.

I got new experience/knowledge with an asus zenfone 5 bricked and "ADB and Fastboot". I follow this tutorial:

a little update on my mini guide should be more clear now

- Download ADB and Fastboot (install at c:\adb for easy access )

- Download and install the Windows zenfone 5 driver

- Download firmware from Asus site for WW ( extract this zip file to get fastboot.img, boot.img and copy these to your ADB Fastboot folder )

- Rename the WWzip into "rom.zip" and move it to your ADB Fastboot folder (for easy typing in cmd)

- Turn Off your phone - connect to pc with usb cable

- Hold vol up and then press power On button of your phone - Keep holding both buttons, it should went into Droidboot screen.

- Open command prompt (cmd) and go to your ADB Fastboot folder (e.g. cd C:\adb)

- Type the following 2 lines: "fastboot flash fastboot fastboot.img" and "fastboot flash boot boot.img" (look phone screen, should say successfully done for both)

- Scroll down(use volume keys) to recovery and select it(use power key) and your phone will reboot

- now that you are in recovery(you can see a droid symbol lying down with red triangle over its stomach)

- Hold Vol Down and press Vol up (menu should appear)

- Choose "Apply update from adb"

- From cmd above type "adb sideload rom.zip"

- Wipe cache/dat and reboot

But in "fastboot flash fastboot fastboot.img" it appear "device not found". I installed PDANet Desktop and some ajusts I could fix the USB problem.

What I've tried (Today):

- If I press vol up button and plug it on PC the LED light is blue and show the USB icon next the clock.

-When I open ADB terminal and type "fastboot devices" it returns YT910YCRMG

-When i tried to flash the new room through the Flashtool the follow message appear:

24/016/2015 21:16:47 - INFO - Device connected with USB debugging off

24/016/2015 21:16:47 - INFO - For 2011 devices line, be sure you are not in MTP mode

I'm sure that the customer doesn't turned the debugging on (he don't know what is this). There is a way to turn debugging on the device in the current situation?

I can't apply the same tutorial from asus because there's no fastboot.img and boot.img files inside the Sony rom .TFT.

Some suggestions? I really appreciate some suggestions.

Thank you
