Sony Xperia X Performance (dora/F8131 & F8132)

Andreas Pokorny

@Tellina Depends on what state your phone is in - when you do "fastboot devices" the blue led has to glow, otherwise it is not in fastboot mode, or the USB cable has issues, or the USB hub in your system has issues.

@kugiigi I was supposed to grab three suzu devices and accidently bought doras - so I had to adapt the port. Overall it is still not as polished, and it does not feel faster - yet. There is still something odd. Moving to arm64 made it snappier and removing the disfunct thermanager also helped. Still battery usage and overall performance should be better.

@Andreas-Pokorny Hello Andreas. Thanks for your reply. I checked the output of the "system-image-cli --info" and it shows that I'm on the:

current build number: 53
channel: 16.04/community/anpok/devel

I've read that there are now other channels, and that I should move to the arm64 branch. I will reinstall the OS using the installer.

@Andreas-Pokorny The previous version bugs still persist on OTA-13, plus camera not working now, any idea how to fix those?

alexmigf

Bugs i found until now:

No GPS detection
Wi-fi disconnects randomly (and sometimes is hard to reconnect, keeps asking for password) - New
When reboot wi-fi connection is lost, need to add password again
Camera doesn't work (photo and video)

I was having major issues. No instructions on here did the job. I am a total newbie, never flashed a phone or used Linux in my life. I expected, the F8131 I bought would just plug into UBPorts and self install - it did not. So for anyone else stuck with this phone - this is the solution:

@kophamerla @Andreas-Pokorny I used bits from you guys and then some tweeks from myself to come up with this solution:

SUCCESS !! This is solution for anyone else, using Windows 10

Get ABD drivers
Unlock Bootloader
Allow USB debugging
Use Sony 'Emma' tool to get Latest software & Firmware available on there - (bottom 2 on list) You need to put phone in flash mode to be seen. (Hold volume down whilst connecting USB to PC)
Put phone in Fastboot (hold down volume up whilst connecting USB to PC)
Go to device manager - check that Android device is showing with ABD device - if not look at other devices for an S1 fastboot device with a warning symbol showing no driver. Update driver - select from computer and put driver location. If this doesn't make the device from other device to Android device, then get ABD from google and use that one.

Get TWRP, twrp-3.4.0-0-dora.img open command prompt in that folder. Type: fastboot flash boot twrp-3.4.0-0-dora.img

Boot up phone, will be in TWRP. Select Wipe, then format data - type yes. Back to advanced wipe - select DATA, CACHE & SYSTEM and wipe them.

Then use UBPorts installer. Put phone into Fastboot, and leave connected to computer until end of process. Manually tell it F8131 as device. Leave fastboot checked, I used channel marked 'stable', I think. Continue on. Phone will boot into UBPorts recovery, and will then install Ubuntu. It will reboot, you'll see Ubuntu robot and 'installing update' phone will then reboot BUT will be stuck on SONY boot splash screen. So hold down power and volume up, releasing power when screen goes black, until blue LED is on - which means its back in fastboot mode.

Then Flash the OEM binaries from: https://developer.sony.com/file/download/software-binaries-for-aosp-nougat-android-7-1-kernel-4-4-tone/ using fastboot flash oem SW_binaries_for_Xperia_AOSP_N_MR1_5.7_r1_v08_tone.img

Do this by opening a command prompt, again, within the folder. When its done reboot phone. This time SONY screen will make way for UBUNTU TOUCH.......YAY!!!!!

@paulmbcufc
Thanks for sharing your findings.
I'm glad you managed to get UT on your phone

jlabon

Installed successfully UT on my F8131 device following above instructions (--> thanks for enabling UT on Sony Xperia X Performance).

However, some functionalities or features are missing which would make the phone ready for daily usage.
Missing feature or no functionality:

Missing feature of Fingerprint sensor
GPS/Position doesn't work at all
Camera photo flash-light not working, photo zoom not working, film recording not working (but simple photo works)
Bluetooth doesn't connect to other devices (e.g. communication systems) and often is disconnecting after a few seconds. And sometimes it cannot be restarted until device is rebooted.
USB-MTP doesn't allow file management from Windows/Ubuntu file management system/explorer (e.g. transfer files to phone, moving files on phone storage to another place on the phone deletes the file, etc). But file system/structure can be accessed for reading files.
No ring-tone when receiving a call. Just vibration is working.
Wifi password needs to be re-entered after re-boot of the phone.

Hope that issues will be solved with daily updates on devel-channel.
Or is there a tweak or trick in place to solve (some of the) issues?
(If there is, could you share it?)

P.S.: Also NFC is not working.

Update:
Now, with the new update (build 112) Bluetooth connection works with communication systems and calls are working in general.
But on car communication system contacts/telephone book is not downloaded and is not possible to use. Also forcing downloads of contacts doesn't work (car communicaton system shows that no contacts are found).

jlabon

2nd Update:
Now (with last update build 115) GPS/Position seems to work, that's great. But satelite recognition needs some time (ca. 20 sec - 2 min).

@jlabon GPS signal acquisition is quite long in general since UT doesn't support A-GPS, Glonass nor Galileo yet. Duration varies according to devices. I noticed that it's quite quick on the Vollaphone (> 1 min) and much longer on Nexus 5 (3 to 5 minutes at least).
