I’m totally new to Sailfish and wanted to install it on a Sony Xperia 10 IV. According to the install instruction I need the model version XQ-CC54.
I bought the device and according to the description it is a XQ-CC54. Looking at the back of the device it also says XQ-CC54 there. But just to be sure I started the device and noticed that the version shown in the settings is SOG07. My questions are:
- Can or should I attempt to change the firm ware before installing Sailfish?
- What model version is the important one? The one printed on the device or in the firmware? And therefore can I just ignore it and continue with the installation?
SOG07 is KDDI locked may not work.
Just tried it because why not.
sudo fastboot oem unlock 0x[insert your received unlock code here]
resulted in:
FAILED (remote: ‘Command not allowed’)
fastboot: error: Command failed
Well on to ordering another device, which hopefully has the correct version on it.

your post is low on details: did you put the device in fastboot mode before running the command? Did you check the bootloader can be unlocked? Find out how to do this via a search engine - I can’t paste the instructions in this forum. In general the SOG models can’t be unlocked, but beware, it’s becoming common also on other models, check before you buy if possible.
I followed all the instructions here: How to install Sailfish X on Xperia™ 10 IV on Linux - The Privacy Respecting European OS and AI Solution Provider
My first issue is that the used device was described as model version XQ-CC54 like required and it even says that on the back of the device. Only in the actual settings it show SOG07. I will send the device back and buy a new one hopefully this time it really is a XQ-CC54
Apparently, they sold you the Japanese SOG07 variant, with the back cover replaced from the XQ-CC54 version. When buying my 1 IV I was paying special attention to this, because it seems to be a common practice. There are several reports in the Nagara (1 IV and 5 IV) port thread from people who ordered the normal XQ-xx54 versions but got various Japanese SOGxx variants and had to return them because they are locked.
Before that, you first need to do the following:
Go to Settings > System > Developer options, and enable OEM unlocking (use the slider even if it appeared greyed out) and USB debugging.
Or, even earlier, open the Phone dialler screen, type *#*#7378423#*#* and check there for Bootloader unlock allowed: Yes (or No) option. If it says No, it’s useless.
It will most probably say No in your case, because the Japanese SOGxx variants are locked.
It doesn’t really matter what it says there because those sellers replace the back cover, or else they wouldn’t sell those devices outside Japan…
