So Lets start flashing this device:

Flashing Xperia could be little tricky.So make sure you have everything beforehand to prevent bricking your phone.

This tutorial is for Android 5.1.1, you can do the same for other versions when available.

Step:1 Check your firmware version (if you already have the newest one, you do not need this tutorial.
Step:2 You need Androxyde xperia flashtool to flash your xperia device. Download from this link.

Step 4:Take the ftf file downloaded in step 3 to folder “Firmwares” included in the XPERIA Flashtool[You might check where your flashtool installed.For me it is C:\Users\administrator\.flashTool\firmwares.

Step 6: Make sure USB Debugging is on your phone.For this you need to enable developer mode.Go to Setting->About Phone->Build Number and tap for some times, It will give you a message “You are now a developer” go back and you can see Developer Option. Go to Developer option and set USB Debugging On.

Unlock your bootloader:

Switch off and disconnect your phone.Open Flashtool and Select “BLU” ,It will ask you to¬† press vol up button and connect usb cable. Once connected in FLASHMODE it will give a popup where you can see your bootloader key.No need to enter it unless it is asked, The tool is itself capable of unlocking however for safer side we can copy and save it for future relocking purpose.

Open the XPERIA Flashtool, click on flash and choose downloaded firmware, than click ok. Important – if you do not want to delete any data of your phone, just uncheck flashing userdata.sin file. All data will remain in your phone, but sometimes it can cause additional troubles. So it is better (and I recommend that) to do the backup of your personal data, than proceed with clean instalation and then restore your personal data.turn off your phone and when Flashtool shows pop up window, connect phone to PC with holding volume down button after few minutes all is done and your phone gets the new firmware

Geeksphone Peak Device driver issue with Windows 8.1 64 Bits

Hi Fellas,

dsc04572-1361806288

I was trying to flash GeeksPhone Peak device on my Windows 8.1 64Bit machine. I tried multiple times but unable to install drivers for device. Windows throws an error as “The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering“.

Hard Luck ? not to worry, The reason of this issue lies in back-end of Windows 8.1 security mechanism. Windows 8.1 only allow s igned drivers to install in the system. The drivers supplied by peak are signed for X 32 BIT version but it is not signed with hash that could be validated by 64 Bit version,

So , The solution! Yes solution is pretty simple, We need to turnoff Windows Signature Validation. To do that Go to PC Settings –> Advance Startup and Restart System ,

The system would start in diagnostic mode with blue screen -> select troubleshoot ->Advanced option ->Startup Options ->Restart

System Reboot and show you some options:

“Choose Disable driver signature enforcement” system starts with disabled signature enforcement. Now you can install the driver, Window will warn it doesn’t verify publisher , choose

Choose “Install this driver anyway”!

Driver is installed now you can flash your device!

Cheers
