Bluetooth not working Ubuntu 18.04 Realtek

Question

I'm using Ubuntu 18.04 on HP 240 G7 and bluetooth is not working. Says "no adapters found" and the switch is grayed out.

These are some command outputs I've run:

~$ sudo lsusb | grep Bluetooth

~$ sudo lshw

I've tryed every possible solution I found but nothing works. I even turned off/on the bluetooth in BIOS. What else can I do?

EDIT AFTER ANSWER

Now bluetooth keeps telling it's off even if I turn it on.

Hm. It should work with this kernel. Please add output of usb-devices | awk '/0bda/' RS= — Pilot6, Jan 22 '20 at 18:46
That's a mystery. There is { USB_VENDOR_AND_INTERFACE_INFO(0x0bda, 0xe0, 0x01, 0x01), .driver_info = BTUSB_REALTEK }, in btusb.c but btusb is not loading. — Pilot6, Jan 22 '20 at 21:07
modprobe: ERROR: could not insert 'btusb': Unknown symbol in module, or unknown parameter (see dmesg) — Javier, Jan 22 '20 at 21:14

I can suggest to report it as a bug by ubuntu-bug linux. You can try a mainline kernel like 5.4 and test if the bug is there. — Pilot6, Jan 22 '20 at 21:17
Did you install any drivers? Maybe that is the reason. Please add output of modinfo btrtl. I didn't see problems with this device. — Pilot6, Jan 22 '20 at 21:19
Before this, I had the same issue with wifi so I did this https://askubuntu.com/questions/1047245/wifi-adapter-not-found-in-ubuntu-18-04 without need to purge bcmwl-kernel-source. — Javier, Jan 22 '20 at 21:24
You don't need any external drivers with the 5.3 kernel. You need to uninstall them all. — Pilot6, Jan 22 '20 at 21:27
I've done some things and this has change a bit. May I get some help again? — Javier, Mar 11 '20 at 19:48

You neet to remove the 3rd-party module that you installed.

Kernel has updated to 5.3 and it breaks BT.

Run in a terminal

sudo apt purge btrtl-rtl8723de-dkms

and reboot.

If the package is not found, run

sudo dkms remove btrtl-rtl8723de/0.1~bionic --all

This was installed from my PPA. Remove it too by

sudo add-apt-repository -r ppa:hanipouspilot/bluetooth

I backported the btrtl from the 5.3 kernel to let people use the BT on older kernels. No need any more now.

I did this and wifi isn't lost, but bluetooth still doesn't work. Now ths switch isn't greyed out but turning it on does nothing. – Javier Jan 22 '20 at 21:45
Did it uninstall the driver or there was an error? – Pilot6 Jan 22 '20 at 21:46
No error. Uninstalled ok. – Javier Jan 23 '20 at 02:24
Added new screenshot. – Javier Jan 23 '20 at 19:09
Screenshots are useless. What is the log now? What does modifo show? What dkms status show? – Pilot6 Jan 23 '20 at 19:13
dkms status shows nothing, and modinfo btrtl shows what I edited. – Javier Jan 23 '20 at 19:21
Now its much better. One last effort. dmesg | grep -i blue. It looks there is no firmware. – Pilot6 Jan 23 '20 at 19:24
And also rfkil list – Pilot6 Jan 23 '20 at 19:30
Added both command outputs. – Javier Jan 23 '20 at 19:32
This looks like a bug to me now. Errors in loading the firmware. Report it to Launchpar by running ubuntu-bug linux. It used to work on older kernels with my module. The've broken something now. Another way is to return to 4.15 and use my module. Post the dmesg | grep -i blue to the report and explain that BT doesn't work. It works for other people with the same device though. – Pilot6 Jan 23 '20 at 19:34
