hello,
I can’t achieve to do this installation.
Do you use TWRP recovery or e-1.17…recovery ?
Because the link for install use TWPR.

How to install:

1. use TWRP 3.5.0.
2. do factory reset (wipe)
3. Flash the firmware, nik,bit or flamegapps , magisk 21 and that’s it.
   Change log:
   20201206- initial build.

When using TWPR 3.7.9_9_karin … then install e-1.17 ROM karin (no windy) with SDCARD (local storage) , the xperia goes in reboot loop with SONY xPERIA logo.

Hi @ledufinfra, welcome to this forum.

@ledufinfra

Flash the firmware, nik,bit or flamegapps , magisk 21 and that’s it.

This is unusefull :

• Firmware was already installed along Stock Sony Android OS
• i don’t know what are “nik” and “bit” for, but “flamegapps” is unwanted in our degoogled android system, and could be the cause of you issue !
• Magisk is not expected during a first “clean install”, better wait that the system boot normally before get root permission…

@ledufinfra

, the xperia goes in reboot loop

1. Please try a FORMAT /data at this point (not a single wipe)

if it don’t works

2. Install the recovery-e using TWRP,
   then install /e/ using the recovery-e → “apply update”

[ledufinfra]

1 . does not work
2 . (flash recovery-e ok), then boot recovery (e/os/) but got :
E: inotify_add_watch failed : No such file or directory
E:[libfs_mgr] Skipping mounting ‘/dev/block/bootdevice/by-name/cache’
E:[libfs_mgr] Failed to ppen ‘/dev/block/bootdevice/by-name/cache’ : no such file or directory
then many failed to read file in /cache directory !

In ecovery-e app i got :

• – Install /storage/BDCCF56/e-1.17…
• supported API 3
• Install completed with status 1
• Installation aborted

I have another one tablet : so, can someone explain the installation step by step ?

@ledufinfra

In ecovery-e app i got :

• Installation aborted

Have you tried to reboot system from there despite the message ?

Have you tried another factory reset at this point ?

@ledufinfra

Here is the summary : (1) install the appropriate Flashing Tools (2) allow “Non Vendor OS” to be installed on the device (2) Check the communication between the PC and your smartphone (5) Download a custom recovery manager (4) Download an /e/OS build (6) Unlock the Bootloader (7) Flash a custom recovery manager on your device (8) install /e/ from your computer, using the “adb sideload” method or (9) Install /e/ without computer using the “Device-Storage…

hello piero
What i’m doing :

• boot Z4 tablet in fastboot (blue LED)
• fastboot devices : ok, got => CB5A2CEZVH fastboot
• then : fastboot flash:raw boot boot.img (cause i got LTE release, but i don’t know the aim of this command …)
• then : fastboot flash recovery TWRP-3.5.0_9-0-karin_20210122.img
• then but in recovery (TWRP)
• then wipe data

[ledufinfra]

Any help ?
when fastboot then flash boot recovery img, i got a lot of message like “Failed to open /dev/block/bootdevice” in the recovery app (after booting in recovery)
is someone have any ideas ?

The only install that is working (from linux) :
On your Linux desktop
fastboot devices => give you device id
fastboot flash boot TWRP-3.5.0_9-0-karin-20210122.img
fastboot reboot recovery

On your z4 tab with TWRP:
wipe/Factory/reset
Launch Advanced/ADB Sideload

On your Linux :
adb -d sideload lineage-19.1-20240409-UNOFFICIAL-karin.zip
adb -d sideload NikGapps-basic-arm64-12.1-20240813-signed.zip
WIPE/ Factory/reset

Then reboot… but nothing work for e / OS

Any better with recent builds (and last for R):

e-2.3-r-20240912-UNOFFICIAL-karin.zip

e-2.3-r-20240912-UNOFFICIAL-karin_windy.zip

There are even LOS19 and LOS20 sources.

@ledufinfra

On your z4 tab with TWRP:
wipe/Factory/reset

Using TWRP 3.3.x-x and format /data instead of simply wipe /data can be a solution for installing /e/…

installing /e/ over lineage also can be a solution for installing /e/…

[ledufinfra]

thank you all of you, i will give it a try.

[ledufinfra]

Ok , good Working with :

• TWRP-3.7.0_9-0-karin-20230430.img
• e-2.3-r-20240912-UNOFFICIAL-karin.zip (on microsd, but probably that adb sideload work too with usb attachement to PC desktop)

[Rookysteed]

Hello,just deploying this very good rom but i got no bluetooth .
Can you help meto make the device available ?
Is there a way to install fix, driver or anything else ?

[Rookysteed]

Can i help for rebuild a rom with bluetooth ?

[ronnz98]

If you provide a fix I can rebuild

[Rookysteed]

Hello ronnz98,
On lineagos 18.1 or 19.1 alex seems to fix the bluetooth.on 20 he dont.
I will give you feedback asap.
Do you have a tutorial for building rom?
(My dev skills are medium)

[ronnz98]

I can try to build new for 18.1 as sources seems to be updated and try to build for 19.1 but cannot guarantee this will work

I made a how-to for building last year:

Howto: Unofficial Builds using repo style for supported lineageOS devices that are not (yet) supported by /e/OS

[Rookysteed]

it will be great, if you can rebuild, this is my job to test.
i will read this how to.

thank you.

[ronnz98]

@petefoth : Could you sucessfully build for LOS19?
I got one error I could not fix:
error: device/sony/kitakami-common/camera/libcameraservice/Android.bp:38:1: “libcameraservice_kitakami” depends on undefined module “qti_camera_device_defaults”

And a lot of sepolicy errors, I think I have the wrong sources for:
device_qcom_sepolicy-legacy

[Rookysteed]

For me the build e-2.3-r-20240912-UNOFFICIAL-karin.zip work fine . Only bluetooth issue.

[ronnz98]
