Re: How to unlock bootloader - Sony xperia X
 

Flashing the F5121 firmware could work (at least with custom roms it only has no dual-sim support so it could be enough to backup the keys).

The drm-keys unlock some functionality on android but won't be needed at all on Sailfish OS or custom android roms (there are drm-fixed-kernels available for custom roms which restore those features).

In many places (eu afaik so you'll be fine until brexit is done :p) they aren't even needed to "restore" warranty since wiping the warranty by unlocking your bootloader is not allowed there.

So unless you're going to sell the phone or you plan on ever running stock rom on it again you don't need to backup your drm-keys (can't hurt though).

Thanks jakibaki, I have no intention of using android or going back to it. I thought that Jolla might need the DRM keys to access some of the hardware stuff (Camera, audio DAC, etc...)

As you helped me in the other thread getting F5121 marshmallow firmware is not an issue but F5122 seems to be a right pain and I don't think I need go through it.

I guess we will know more next Wednesday. Once again thanks for helping :)

Re: How to unlock bootloader - Sony xperia X
 

Hi folks,

so in order to install Sailfish X do I need to unlock bootloader using Sony's instructions (and install android sdk and other stuff)? Or does Jolla provide some tool for this on wednesday or can I unlock bootloader using Emma?

Re: How to unlock bootloader - Sony xperia X
 

From what I understood EMMA can't flash anything with a locked bootloader. So you will to first unlock it before using EMMA.

I haven't unlocked my bootloader yet but with doing some reading you don't need the whole SDK to unlock it. But I will wait to see Jolla's instructions first before doing anything.

Also if you have a windows PC sony has a video on how to unlock the bootloader: >>Video Here<<

I am following helpers:

My XperiFirm -Create your FTF firmware [1302-3140] file is always failing at the end of the download with unpacking failing. I am using Mac.

@mousse04
Should your FTF version work with phone "Region: Nordic (Generic) [1302-3140]"?

Re: How to unlock bootloader - Sony xperia X
 

I had that on Linux after one successful try. I tried deleting the directory created by flashtool (something like /root/.flashtool). Next try was successful. So maybe this might help in your case as well.

Re: How to unlock bootloader - Sony xperia X
 

Aaand - boot loop with Mousse04's file above.

Edit.

But now managed to get working with Mousse04's ftf. I totally missed step "Right at Wipe , we select everything from APPS_LOG, DIAG, SSD, USERDATA"
After this I boot loops gone.

Thanks for the file!! :)

Now I can continue to DRM stuff...

Please note that as of today you need to update Xperifirm:
https://forum.xda-developers.com/cro...oader-t2834142

Have to manually amend Androxyde's Flashtool to account for this change as no longer connects to server by replacing Xperifirm.exe in Users > Name > .flashTool with version dated 16/10/2017 to restore XF icon function.

Re: How to unlock bootloader - Sony xperia X
 

Back in August, I struggled with this subject using a Windows 10 pc.

I ended up using flashtool-0.9.23.1-windows.exe to get the necessary drivers onto my pc. That worked well, but today Norton Security claimed there is some malware hidden in the tool, within the file flashtool-drivers.exe. So it deleted this file.
The name of the malware: Heur.AdvML.B

To whom it may concern...

Re: How to unlock bootloader - Sony xperia X
 

Yes. I noticed this aswell :)
But, consider this. Flastool contains exploits for many things. For Example rooting the device.
Sure, its “malware”, but its intentional ;)

Just remember to get it from the (more or less) official sources !
