Hi All Can I ask help from the community. I am not very technical but usually can follow instructions but I seem to be having problems getting Sailfish X onto my new Sony Xperia X.

As per the "What you need to begin" section here. I have everything needed. https://jolla.com/sailfishxinstall/

Section 1. I need to follow instructions for a locked device. (Option 1) 1.1.1 / 1.1.2 / 1.1.3 ==> Completed successfully over a period of about 1 hour.

Section 2: 2. Install the fastboot driver 2.0 to 2.16 ==> Completed successfully (Instructions perfectly written)

Section 3: 3. Extract the Sailfish OS .zip file 3.1 and 3.2 ==> Completed Successfully

Section 4: 4. Unlock the bootloader. This is where things start to get messed up for me. I have tried to follow these instructions in a Windows PC and a Mac. I have the phone in developer mode USB debugging "On". And OEM unlocking "On

The instructions on the sony web page for windows was not very clear at all so I decided to follow the Mac instructions. I also found this question answered by jolla for mac on this page https://together.jolla.com/question/165844/unlock-your-boot-loader/

I have followed these instructions as best I can Connect the Xperia X pressing the Vol up button while connecting to the computer. I installed Android Studio for Mac

cd ~/library/android/sdk/platform-tools ENTER ==> This worked flawlessly /fastboot ENTER ==> This provided a lot of information of which I could not find any error (so I assume this worked) ./fastboot -i 0x0fce oem unlock 0x################ using the ####unlock code The 0x code I have from sony replaced the 0x################ when I pressed enter it do nothing. I didn't get an error or anything. So I assumed it worked. As there was nothing I could do I unplugged the phone thinking it was successfully unblocked.

Back I go to Jollas instructions.

Section 5: 5. Getting the Sony vendor binary images 5.1 / 5.2 & 5.3 ==> Completed successfully

Section 6: 6. Flashing Sailfish X to your Xperia™ 6.1 to 6.6 ==> Completed Successfully

At this point EMMA pops up saying "Locked Phone Detected"

Can somebody please help me. Ive been at this nearly all day. I know the solution is easy (if you know how)

Thanks in advance

when you start your xperia - is there any warning, that your phone is unlocked? if not, than sth. is wrong. - did you check at the windows device manager, wether the fastboot-driver is installed correctly?

Thanks for the reply. When I start the Xperia it starts up as normal (with Android) - No warning or anything unusual. Device manager installed the fastboot driver without any issues. Sean

All signs that bootloader was never unlocked, you get output in terminal how long process took if successful and you can't miss the yellow on black start up warning on unlocked device. You don't mention whether using Windows 10 as can be an extra aggravation getting correct driver installed. Must admit that I unlocked it upon Windows 8 machine but subsequently flashed Sailfish OS using Mac

I 100% agree with you the devise was never unlocked. So when I entered he command "fastboot " now it does nothing. But earlier it took about 1 to 3 seconds to come up with a reply (but it looked like a "help" command (screen shot is captured if required) Im using windows 7 for all the Jolla notes and Mac OSX 10.9.5 for the unlocking process from sony as the PC instructions didnt make sense. I have access easily to windows 7 / Mac osX 10.9.5 , Ubuntu latest version and linux mint latest version. Im not very technical but LOVE linux:)

Cheers Sean

For me on Win10, fastboot devices does nothing for now because I haven't yet installed the drivers. So I'd say it's possibly a drivers issue.

This doesn't seem to work for me. Can this be unlocked through Linux or Mac. The windows instructions from sony are not helpful at all.

To unlock the bootloader it can be done with visiting Sony


Or by using the Flashtool which not only can reset the phone to stock firmware which might be need if your Android version is less than 34.3 but will also unlock or relock your bootloader too.
