Factory Startup Service after Factory reset

[Pras13]

Hi,

Everytime the phone restarted or turned on, message "FACTORY START UP SERVICES, PLEASE WAIT FOR POWER OFF BUTTON" always appear. And when ever i press the "onscreen off button" the phone turned off, and the message didnt disappear when i turn it on again.

This issue happen after i did "factory reset" after upgrading to Oreo via OTA update, i did factory reset because its getting a little bit laggy.

What i have done so far :

1. Factory reset again

2. Repair with Xperia companion

3. Reflashing the same firmware using flashtool

But no results, the message still appear, and the only way i can use the phone is fastly going to apps and deactivate com.sonyericsson.startupflagsevice.

Someone have similar problem with me?

Please help

Thank you

Looks like im the only one facing this issue..

Update:

Intalled The last update, After installed the January Security patch, the phone restart as usual, and the problem still exist...

Factory StartUp Service, Please wait in screen Power OFF button...

Tapping power off, turn on the phone, and it start appearing again..

I am also facing the same issue with my Xpeia XZ after update to Oreo. Anyone has the solution please?

[Pras13 · Accepted solution]

Well finally i can solve the problem myself. (at least for my XZ)

What i did :

1. Flash Marshmallow firmware using Flash tool. Firmware Version 39.0.A.1.250

2. Turn On the phone, in the first boot, Factory Startup Service show up, and i press on Screen Turn Off button

3. Turn on the phone again, this time Factory Startup Services doesnt show up.

4. Flash Oreo Firmware using flash tool

5. Turn On the phone, in the first boot, Factory Startup Service show up, and i press on Screen Turn Off button

6. Turn on the phone again, and NO Factory Startup service message Appear.

7. Try to restart multiple times, Factory Startup service never show up.

But I never try to Factory reset, because im lazy to do all the step if the Factory startup service message appear again.

Hope this can  help people with the similar Problem.

I resolve my problem by doing step stated in post 6.

Basically what i did was Reset the phone to the original Firmware which is Android 6 Marshmallow.

Because we cannot go back to previous firmware from the phone, so I use Flash tool to manually flash original firmware (Android 6) to my phone.

Hope that steps also work on your phone.

Nb: flashing original firmware using flashtool didnt void warranty

Hi I have a Sony Expedia L2 it will not start my phone because I forgot my password please help 

[hoangz5]

don't even have to do all these hassles !  and these are dangerous if you mess up the flashing things...

You just need to wait for the phone to power off itself. Waiting time from 40-60 min. 

Sony has an English problem : instead of "power off", it should says "powering off" so that people know that the phone is working, that is : it is in the process to powering off the phone.
