My Xperia 1 II (XQ-AT52) fall into reboot loop that cannot get into system. So I tried to flash it by Sony Companion and flashtool. I pressed the volume down key when it turned off. After few seconds the green LED turned on, i connected it to computer over USB cable, but my computer did not recognize the phone. Strangely, I can connect it to computer under fastboot mode(the blue led turned on)! I have already installed flashmode drive and fastboot driver. Help me plz, THANK YOU.
When my XQ-AT51 fall into reboot loop, my only way (I'm not an expert, just playing with my device) was to relock the bootloader
fastboot oem lock
And made softare repair with Xperia Companion.
(After that I found my IMEI un the SIM card tray to get the code for unlocking the bootloader)
Hope it helps!

Hi,
I faced with a problem what I never seen before:
The device works normally, its on 28.0.A.7.24. I tried to update with PC Companion, it recognized the device as E6533, and offered new software.
Once process started, it downloaded, then phones rebooted instead goes to flash mode. After it (until next reboot), phone completely gone mad:
overheated, not asked for pin code, also IMEI was not available etc.
I tried with Flashtool too, but holding VolumeDown not works. It close to immediatelly drops the boot screen, and never enter flashmode.
Had anyone meet with this issue? How could I fix it?
Fastboot mode is working fine by holding VolumeUp, but flashmode not.
Thanks for help,
Your driver usb may be update,,new pc/laptop come with usb 3

Are you sure that your battery is charged?
Try this: press and hold power and volume up button for 10 seconds and see does the phone vibrate.If vibrate flash again via flashtool.,he should works.

Battery was fully charged and I've tried that but phone does not response at all to flashtool. When plug in to PC, in device manager under USB controllers, it sees it as SOMC Flash Drive. I think the phone boot is dead.

Thanks for your help...The phone was flashed successfully with flash tool with flash file E6553_28.0.A.4.8. After flash done, phone was dead, cannot power on anymore. Now when I tried to flash it again, volume down, insert USB the flashtool show as: Device detected with USB debugging off. It doesn't go to flash mode anymore. I took the back cover off, remove battery connector flex cable and connect it back and try flashing many times but flashtool will not detect phone in flash mode..PC can detect phone because it makes connecting sound on PC but detects as what mode I don't know. In device manager, it doesn't show any device in com port but it shows SOMC Flash Device in USB controllers. I tried to press volume up + power but nothing happened. Once again thanks for your help.

As I understood, you tried to downgrade. Am I right? I heard that sometimes downgrading causes hard brick. I don't know how to fix it but only option is bringing service.

I got my Xperia SP bricked, on boot loop showing Sony logo all over again and red LED turning on and off. I tried getting into the flash mode, but I can do that only for about 10 seconds, after that Flashtool shows "Device disconnected". The LED goes from green to off, to the red with Sony logo for a moment, and then back to the green, showing 100% battery charged icon and Flashtool says "Device connected with USB debugging off". I can't fix it using PC or Xperia Companion. I tried on another computer and got the same result, flash mode works just for a moment. When connected to the PC, it see my phone as "mass storage device". The only thing I can do is get into fastboot, but I have locked bootloader... Please help
then try and get stock kernel and flash through fastboot that should fix problem if not then try going on flashtool and exclude everything exept kernel and when it asks to connect u might get lucky and it flashes it very quick,only other option try downgrading flashtool http://www.flashtool.net/downloads.php pick bottom one
Hi guys! I need your help. I have z1 with ROOT and custom recovery and i would like to update it to android m. The main probleme - bootloader, i should unlock it. But i can't do it because phone doesn't determined by pc in fastboot mode or flashmode and when phone is off doesn't determined at all. But even when phone is on, pc detected phone not always, just sometimes, and phone doesn't charging. ADB drivers is installed, drivers for flashtool mode and fastboot is installed. Command window says "waiting for device" when i want to boot my phone in fastboot. When phone is on ADB works fine. So i've read many topics about problems like that and didn't find the solution. Maybe can anybody help me please?
In ADB , use the command: adb reboot bootloader
The phone will reboot and you'll be in fastboot mode and the phone will show a deep blue notification light.
You need to install fastboot drivers from the driver package bundled along with flashtool before this. So u have to donwload flashtool first
Also, if u're going to unlock the bootloader then back up your TA partition.

Yeah, I did it, the phone was showing blue led, but then it goes nothing, then pc doesn't "see" the phone. I have already installed flashtool and drivers with it for fastest and flashtool. Also I have already made a backup of TA through flashtool.
So I can do something with phone through flashtool or adb when phone is on, but when phone is off I can't do anything. I have heard that reason of that problem can be broken phone's USB port. What do you think?
And sorry for my terrible English
I've connected phone to pc in flashmode through NDR Utils, but fastboot still doesn't work
honestly, im stumped!! . AFAIK its not a problem with the usb port cuz as you said it works fine with adb. Did you try a different usb cable.
You should probably try to reinstall the fastboot drivers
But if you just wanna unlock the bootloader then you can do that with flashtool I think.

Hi! It's me again And i still didn't solved my probleme. So, i can connect my phone to PC and it recognize as Android device -> ADB interface, and as Xperia z1. If i just connect powered off phone to PC or connect phone in flash mode, then it recognize as USB devices -> SOMC Flash Device, is it right? Ok, when i want to connect phone in fastboot, phone shows blue LED and it goes nothing, PC don't determine the phone and i can't unlock bootloader
