Hi
I just found my old phone in my drawer and it seems to be soft bricked. It's running stock android with no usb debugging, non rooted. 100% stock. When I hold the power button it shows the sony logo but it stays there forever. I can access fastboot mode, however its not very useful as I can't flash (no unlocked bootloader + no usb debugging).
I can boot into flash mode by holding volume down. It shows a green LED but on windows 10 it shows "Unknown USB Device (Device Descriptor Request Failed)"
I already tried the changing the power options on my PC, it didn't help.
I have installed the USB drivers from flash tool (All of them)
Any suggestions on how to unbrick it?
Thanks
Hi. Have you already tried to use Xperia Companion? Usually their instructions on "Repair Device" mode are more than enough to unbrick your phone!

Hi there,
yesterday I tried to root my new Tablet Z (16GB, LTE, Model: SGP321, Firmware: 10.4.B.0.569) and it doesn't start since then.
I used an ubuntu live CD for all these tasks because fastboot doesn't work on my win 8.1 and my debian wheezy didn't have the libc-dev needed in its repositories (didn't want to mess with packets that weren't yet integrated into my OS).
What I did:
unlock the bootloader according to http://unlockbootloader.sonymobile.com/instructions
I followed the instructions here: http://forum.xda-developers.com/xperia-z/general/how-to-root-10-4-b-0-569-t2590781
a few annotations to this:
the firmware rar didn't include a "Recover.zip", so I used the boot.img directly inside the firmware rar
although sony and this CM tutorial use the "-i" parameter of fastboot, I didn't use it because it wasn't used by the tutorial
after I did the "fastboot reboot" step, the device wasn't listed anymore when typing "fastboot devices", which, I think, is okay since the device should restart then.
I think it didn't really restart, because the LED on the side glew red.
I tried to turn on the tablet but it didn't do anything (the LED kept glowing red).
I tried holding vol up and power for a few seconds (until the LED blinked first once and then three times) but the tablet wouldn't do anything except for the LED glowing red. at somepoint, the LED would turn off (I think that happened when I hold vol up and power for more than 10 sec).
I was able to let it glow red again by pressing vol up and power again and release the vol up button before the power button.
I also tried to use the PC companion on my windows machine to repair the tablet but the tablet wasn't even recognized (either using the fastboot-procedure by holding vol up while connecting the tablet nor normal plugging in...)
any ideas what I could do next?
Same Problem!
Hey wullxz!
I have the same problem. Red LED most of the time, and I cannot make ANY USB connection to the PC. The tablet won't show up in the device manager. So obviously cant use flashtool, nor PC companion. Ive tried all this volume up and down button stuff, but simply cannot get it to show up on the computer.. Tried a different USB cable as well.. Same issue. The USB port is definitely not broken. Its brand new..
Have you found any solution ? Or anyone else? Mine just got back from Sony Repair.. they wont fix it cuz they detected that Ive tampered with the original software.... meaning Warranty Lost!
Great!
hi,
i also sent mine to sony for a repair. i wrote that i did a firmware update and the tablet wouldn't boot afterwards.
i didn't try the bootloader-unlock again afterwards.
Help Needed!
Tablet Z with unlocked bootloader and rooted 10.1.C.0.370
My issues occured after a downgrade to 4.1.2.
I CAN:
1) Start my tablet, everything normal...
2) Charge my tablet
3) Go into safe mode
4) Go into fastboot mode (solid BLUE LED)
5) Use the memory card and use root apps (maybe this could help restore?)
I CAN NOT:
1) Get my PC to recognize that a USB device is connected. Neither in Mass Storage mode, Media mode, nor fastboot mode.
- Tried with several cables and computers (this is not a driver issue, since it won't show up at all in device manager)
- Flashtool obvious;y says, no device connected
2) Get in to flashmode: device blinks red for about half a second, then green for half a second, and then LED is off. Nothing recognized via USB on PC
3) Get into recovery mode
4) Update over WIFI (fails because unlocled bootloader I suppose)
Any help would be greatly appreciated!
i think you should open a new thread for your problem because it seems like it's not really similar to my issue.
you should get more/better replies in an own thread.

let it charge to 100%, check for flashmode drivers installed and then try attaching it to pc only when flashtool asks you to do it.

Hey thanks for your reply... It wont go into flashmode... Theres something fundamentally wrong.. I cant figure out what... I leave it plugged in for 48 hours..but it doesnt really get full.. the most Ill get the orange LED.. like 50%... now its on since about 12 hours.. no LED on at all... strange..
But yea.. no flashmode... Nothing showing up when connecting the USB cable... nothing in device manager..and therefore flashtool sees nothing!
SOLVED
Problem solved! I can't believe it. Two bad(?) USB cables. Bought a new one, charges fine, flashmode fine. Flashed stock ROM.
However the Camera still doesn't work. Maybe the problem of the cable inside which may have come loose!
Hi everyone, i ask for your help cause i have a common problem but the fixes i found in the forum didn't work for me: my ZenFone 5 stucks at "Asus" logo with a "loading loop" wheel below that.
I know this post may be long but i beg you to read all steps:
1) Phone stucks at logo, but could enter recovery (pressing vol + down), i've updated it via external SD card (official firmware but didn't work) then i've wiped data and did a factory reset. Phone still stucks at logo.
2) Now i can't even enter recovery mode... when pressing vol + down it shows 2 options but whatever i choose the phone reboots. If i press vol + up it says "CSC mode, long press power to restart. Phone still stucks.
3) Now (after some time) the phone's screen doesn't show anything, nor charging icon or notification led when recharging, but strangely the computer recognizes it as a device when connected via USB cable, and the led turns on when i do this.
A friend told me to follow a guide that says to install "Intel Soc USB driver", i did that. After installing, when connecting the device, 2 things should pop up in Device Mangager under "Intel Soc": CloverviewPlus Device and Intel Soc USB Driver... but the second one doesn't show to me
I've also tried Asus flashtool guide... at step 4 it says to click in the box icon and choose the firmware RAW file, so i've downloaded a raw firmware for the ZenFone 5, but oddly it doesn't let me choose any raw file.
Note: the phone is recognized by the pc as "QHSUSB_BULK", so i've tried to update its driver with qualcomm drivers, and now it's recognized as "Qualcom MMC Usb storage device". But i think i've did a wrong thing cause my friend told me i should have choosed some kind of official driver
Thanks in advance for your help
Hi,
My M4 won't recognized in MTP mode.nothing happens when i connect the cable,just charging mode(Not asking to choose between charging mode and MTP)
today I wanted to flash a new firmware (E2333,UB,usb debugging on). But I cant come to Fastboot/Flashmode . In Windows a message comes, which says that the device get not fully detected. On the device manager I get "device not recognized" and the hardware id is USB\CONFIG_DESCRIPTOR_FAILURE or USB\DEVICE_DESCRIPTOR_FAILURE. I also followed the guide the, but without luck: http://troubleshooter.xyz/wiki/fix-u...equest-failed/. And drivers are for sure installed (also installed at least Xperia Companion)
I'm sure of drivers bcuz other phones do ok with drivers and get into flash mode without problem.
also tried different cables and computers.
Even replaced whole micro usb socket with a new one but nothing changed!
I did:
... power off -> hold volume down + plug usb -> "device not recognized" and red led and sony logo then gets into charging screen
... power off -> hold volume up + plug usb -> device not recognized" and red led and sony logo then gets into charging screen
... power off -> hold volume up (and also a try with vol up+down) + power till the 3 times vibration comes. but after that it also not boot into flashboot/fastboot.
... wiped the data/internal partitions from recovery -> same like before
Finally wiped system partition and installed PexoRom system.img from TWRP's Terminal,after boot nothing changed!!!:crying:
Any idea what is wrong with my M4 ?
It's very often when one of two ram is not working.
I mean it's a hardware problem. Are you able to check in settings how much ram shows ?
If something like 883mb,if Im right then you have to buy new motherboard.
So basically I suddenly got this system ui error which caused my phone to go into a bootloop eventually when starting up you could only see sony logo and it would stay on.
I tried to use xperia companion to do a software recovery but my phone would not be recognized. (the led does turn green when you press volume button down)
I tried using flashtool and installed drivers without driver signature but again when flashing it doens't recognize my device.
When the phone is in fastboot mode the device is recognized by flashtool. I tried it with 3 different pcs and 3 different USB cables and nothing.
I have never done anything to my phone so the bootloader is still locked.
I was wonder if I can still recover my phone but than via fastboot mode.
phone specs:
Xperia z2 d6503
os: marshmallow
kernel: 23.5.A.1.291
Thanks in advance for any help

Hi red5815,
Are you certain you can't boot into EDL mode? Try the procedures below and let me know If you still can't enter into EDL mode.
Note: Make sure you have all of the necessary USB drivers installed (So your PC can recognize the connected device when it is connected to EDL mode)
First Method
Turn off your device
If you are in CrashDump Mode, I think you must hold down the power and volume up buttons for around 8-10 seconds (Until the screen goes off)
Then, hold down the volume up and volume down buttons simultaneously, and your device should enter EDL mode
While holding down both volume keys, connect your device to your PC via a USB cable
Your device should be recognized
Release the volume keys and press the "Start" button on MSM Tools (This will wipe your entire device, and if the bootloader was unlocked, it will relock it)
Second Method
Start MSM Tools and wait for the "waiting for device" message to appear (Before you start, keep in mind that this process will erase your whole device and relock the bootloader if it was previously unlocked)
Turn off your device and connect one end of the USB wire to your PC
Then connect the opposite end of the cable to your device
For a few seconds, press and hold the volume up, volume down, and power keys simultaneously
Your device should be recognized, and the flashing process should be started
Edit: Added proper warnings
pressing and holding the volume buttons only make it boot to fastboot.

Hi red5815.
It takes a few attempts to get it right. Just make sure that all of the correct drivers are installed. Also, perhaps try using a different cable than the cord that comes with OnePlus Nord N200.
Without being connected to your computer, complete the button combination, and after a second or so, plug your device into the PC with MSM tools open (While still continuing the button combo). The screen will produce a momentary flash of black/green and it will ultimately connect to the MSM tool.
If that doesn't work, try this:
Open MSM tools and pick the appropriate parameters
Make sure your device is turned off
Connect the USB cord to your computer and then connect the other end to the OnePlus Nord N200 while holding the volume up and down buttons
It will then display the "connected" status in MSM tools for perhaps 2 or 3 seconds
Immediately click "start" in MSM tools (This will erase the whole device and relock the bootloader if it was previously unlocked)
Edit: Added proper warning

Red5815, great job! I'm glad you were able to get your device operating again.
