I have a 180€ mint condition used offer i would like to accept or decline in the next hour.
So, will i be able to flash a Telekom branded Xperia X?
Thanks in advance!
provider-branded models usually don't allow you to unlock the bootloader, which is the essential part of installing SFOS on the device.
You can check this by dialing "*#*#7378423#*#*" (or *#*#SERVICE#*#*) and then select "Service Info" -> "Configuration". There you need so have the entry "bootloader unlock allowed: Yes". If it says "No" or the entry is missing, you can't unlock the bootloader and therefore not install SFOS.
If you can't check the setting, I'd refrain from the purchase as provider-branded devices usually don't allow for that.
