PLEASE HELP ! While updating My Xperia Z1 , my pc hanged during the process and .

[Alam_X]

While updating My Xperia Z1 , my pc hanged during the process ( so , installation of update was interrupted , guess it's same as getting your USB connection disconnected )and now the phone won't turn on .

Its shows the Sony Xperia logo , then shows a black lit screen , and that's it , nothing else happens . I can only turn it off by pressing and holding the power+up volume button , but it turns on automatically if plugged in for charging or in PC only till it gets that black screen .

I tried to flash it with a flashtool (Emma) , but it says phone locked , but since it can't even be turned on , i can't unlock it .

It's a store bought phone and is not of any contracts with any mobile service provider or anything like that ....

Funny you know ... my PC had to crash at the moment i was updating it .... my luck ....

Anyways , now please can anyone tell me what i can do ? I'm sure there is a way i can fix it using my pc and other downloadable software , so please can some one help me how i can fix this problem ? I don't care if i lose all the data on it , i just want my phone back ....

Charge your phone for one or two hours, then repair your phone with pcc

It'll be wise to use a different PC

Emma will only work with phones that have an unlocked Bootloader that's why you had the message locked - It's in the instructions what the program is for and how it works however

Try performing a system repair using PC Companion as this will often fix issues - This will factory reset your phone and erase all data

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

Thank you for taking your time for helping me ...

you said 

"Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process"

there is no " Repair my phone/tablet" option  

also , like i mentioned in the question , the phone auto starts up and goes to black screen after a minute and then pc companion can't detect the phone , then i have to power+volume reset it ....... 

[Thommo]

There should be the repair my phone option and to connect when prompted during the repair you hold volume down and connect your USB cable holding volume down untill the process begins - If you don't see repair my phone option then you aren't selecting the correct options

Problem Solved ,Thank you  very much !! 

For those who might face the problem and stumble upon this thread after googling  

Read above mentioned comments 

Now here's what I did :

Turned the phone off by power+volume key method , then plugged it in to the pc via USB and opened sony pc companion , entered Support zone , then entered the Update device option , then I Unplugged my device , only after doing this a window pops up with  Repair my phone/tablet in blue text , then i clicked on that and followed the simple instructions ..

It's basically what Thommo said , only i was so freaked out at that time that i failed to follow his instructions to the letter  

So now my phone is back to normal , and , it got the latest lolipop update !

Problem solved i guess  but Thommo , i need to disturb you again with  just one more  question ,  since at the very beginning , the update process was interrupted , and now i got lolipop after  the repair ,without needing to update again ,  so has the lollipop been installed properly on my phone or do i need to use any other flashtool to re-install lollipop ? 

again , Thank you ... 

[Thommo]

Lollipop has been installed correctly - A system repair is a clean install compared to an upgrade which overwrites things
