[Xperia Z5 General] arftrooper2:
First, download Flashtool. You can get it here: ht tp: // w w w. flashtool. n e t /downloads. php

Once, done, install completely.

Sorry, since I am a new user, I will have to space out the URLs.

Next step, download the software needed to activate the fingerprint scanner and flash your Xperia Z5 to get your scanner working. My recommendation is to download the General Latin America software version, in order to do this you will need to click on the XperiFirm tab of the Flashtool, but make sure you are running the latest version: 0.9.23.2. If not, download the x10flasher.jar file and replace it with the one located where you installed the Flashtool.

Find your model, in this case Sony Xperia Z5 > E6603

Download the General Latin America software and the US Customized version just in case you mess up, which you shouldn't.

Now in order to do a flash of a stock ROM, you will need to have unlocked your bootloader on the Sony Xperia Z5. Please visit: ht tps: //developer. sonymobile . c o m / unlockbootloader / scroll to the bottom of the page.

You MUST perform a check first to see if your phone allows boot unlocking, directions in link.

Here, Sony will help you step by step to unlock it, once checked and you receive an email, visit the link and download everything BUT the android studio sdk (you don't need it) just download the ADB bootloader unlock tool. Do the exact step by step as it says on the page and make sure to include your unlock key.

Once unlocked, check to make sure using the same way Sony told you to check earlier.

Now let's go back to the flashtool, here you will go to tools and create a bundle. Select the General Latin America software, on device, double click and scroll down to Xperia Z5 then select E6603. For the next box put in General Latin America software, then the version, it'll probably be something along the lines of 32.3.A.0.376. you will see a list of files on the left box, transfer all the files EXCEPT the files ending with .ta to the right. then hit Create Bundle.

Before you do anything else, go to the place you installed Flashtool and install the drivers in the drivers folder, select the first two, should say flashmode and fastboot drivers, then select and find Xperia Z5. Once done move on to the next step.

Turn off your Xperia and hold down the volume down button, while doing so, connect it to the computer. If you did it correctly the light should flash red, then green, then turn off, then a steady green light on the notification light. Click on the lightning symbol and click connect in flashmode. Then select the location of the software (Remember to select General Latin America) Fill in the same stuff and then on the box select Sony Xperia Z5 using the little arrow, then again to E6603, it should say General Latin America and the software number. Select Flash and wait patiently.

If all went well, it'll say you flash finished, disconnect your phone and boot up.

Should you encounter any issues and such, reply back. Sorry this isn't very step by step, but it is just in the way how I would tell someone. (I would have included screenshots if I was using the computer I used for flashing my Xperia.) If needed I can do it more in-depth.
