Xperia Z5 Boot Up and Reboot Loop

I have this issue after trying to boot the phone with USB OTG + Mouse. My touch screen is not working and i remember that i could use a mouse with OTG. So i follow an instruction in the forum to Reboot the phone with the mouse plugged in. After that i am stuck with reboot loop. Sometime it will boot into the screen and for awhile it will restart. And the reboot loop continue. 

 

Any advice is appreciated.

 

Thank You

Hi @nicholaschong12,

I'm sorry to hear about this. Slightly frowning Face

If you remove the OTG cable and the mouse and start up the device as normal, do you experience the same behaviour?

If it starts up normally without the OTG cable and mouse plugged in I would recommend that you try with another mouse and secondly with another OTG cable.

Let me know how it goes! Slightly smiling Face

Re: Xperia Z5 Boot Up and Reboot Loop

try to remove simcard and memory card then try to boot up.

 

if your device is still connected to the internet, it may have sync some of your contact and other app data to your google account.

 

if your media is save to sd card then you can remove it before you perform software repair..

 

try to boot device by holding power button and volume down button,

Re: Xperia Z5 Boot Up and Reboot Loop

Thanks for getting back to me!

You won't be able to create a backup using Xperia Companion if you can't start and unlock the phone. Slightly frowning Face

Did any of the suggestions provided by @nolramlb work for you? Or are you still stuck in a boot loop? If you are I would suggest performing a software repair using Xperia Companion.

As @nolramlb wrote some of the data in your phone may be saved on your Google account. In addition to that, do you remember if you have used the automatic backup in Settings > Backup & reset? If you have done that you will be able to restore that data after the software repair.

Xperia Companion will always show the message about your Google account because some of our devices (Xperia Z3+ and onwards) have a inbuilt anti-theft protection that requires you to authorize yourself with your Google credentials after the phone has been reset.

When you have performed the software repair and you plug in the OTG Cable and mouse you might have to restart the device once before you will see the cursor on the screen.

Please keep me updated! Slightly smiling Face

Re: Xperia Z5 Boot Up and Reboot Loop

Hi @Gamazta1, sorry to hear that you are experiencing the same behaviour. Slightly frowning Face


I'm sorry for the late reply. I have been out of office due to vacation.

When you are trying to perform the software repair, do you get any error messages along the way?

If you do, try turning any antivirus programs and/or your firewall off during the repair and see if there is any change.

Let me know how it goes!
