Please add your suggestions to improve the documentation for the Sony - Xperia Z5 - sumire here …
I’ve just installed /e/OS on Xperia Z5 and went well. I am super happy!
The link for downloading the Custom Recovery in the /e/OS install instructions is broken, I used the TRWP custom recovery that I downloaded from here:
https://xdaforums.com/t/twrp-z5-twrp-3-2-3-for-xperia-z5-z5c-and-z3.3571050/
For unlocking the bootloader with Sony’s code as said in the install instructions, one has to add “0x” just before the code, like this
$ fastboot oem unlock 0x<your_unlock_code>
otherwise fastboot returns a formatting error
Hello,
I had an issue with the recharge, e.g., after reaching 1% battery and turning off the phone, I tried recharging while being off but it didn’t work and I could not even turn it on again.
But I manage of solving the problem by booting into recovery mode and then rebooting it from there. So I am super happy again
