          Mannn ur fone has been bricked, seems u didnt follow the procedure. well u have to unbrick by making a hard reset or downgrading your firmware. you could also find a way to recovery mode, don’t have much to say

      You don’t have to, just press the “Volume Down” button and insert USB.

    • LinnKhant 2002 December 28, 2015 at 5:19 pm - Reply

    Its saying this type of file cant be opened in ur phone

    • Anurag Kumar April 14, 2015 at 7:59 am - Reply

      It is not to be opened in mobile, PC is needed to store the file and to flash it on mobile.

    The problem I am facing is before the flashing process, cause when I am trying to install the drivers in the drivers folder it is continuously failing with cross marks, also I could not be sure which one to select from the list. Another thing, during connecting the phone in flash mode, do I need to turn off the handset. I own a Xperia Z1 Compact and i am new in flashing. Any kind of help during this procedure would be highly appreciated. Thanks in advance.

    • Anurag Kumar April 14, 2015 at 7:56 am - Reply

      install pc companion , connect your device , disconnect. It should solve the driver issue.

      Yes turn off your handset and then connect your handset in flashmode (steps mentioned in post)

      • Pratyay April 18, 2015 at 11:23 am - Reply

        Sorry for the late reply, and yes, it worked. I tried the procedure a few times and then it worked. 🙂

    Anuragh, i have two doubts, pls clarify it…

    1. can i go back to kitkat,if the booting fails??
    2. can i get the indiAn update,when it rolls out here! ??

    • Anurag Kumar May 24, 2015 at 1:21 am - Reply

      1 – If you get boot loop error then you have to flash the KitKat ftf to go back again.
      2 – Next time you will get OTA/PC Companion update notification depending upon the region’s ftf you flashed.

      If you want all updates as per Indian region’s roll out then you must flash Indian region ftf only other update time roll out will depend on the region’s ftf your flashed.

    • Anurag Kumar June 1, 2015 at 3:09 pm - Reply

      1 – Use PC Companion for backing app data and for app apks use Avg Antivirus for mobile.
      2 – Skip the step “Wipe data” while flashing the ftf file and then your app data will not be deleted while flashing.

    When the flashing is supposed to start (once everything is ready and the phone is connected in flashmode) nothing happens, las message shown is “Device connected in flash mode” and nothing else happens till a minute or so later, when phone just reboots by itself and the flasher says that the device has been disconected. What can I do??
