@lduboeuf Thanks.

How would it possible to do a keyword search through the data of the agenda app? Would the grep command in the terminal app do the trick? Is this data in text or binary form and in what directory?

It turns out that the backup functionality was never pushed to the official installer.

The backup function seems to have disappeared from the installer. What happened to it please?

Thanks @MrT10001. It is indeed on GitHub:

$ cat ubports-installer_0.10.0_linux_amd64.deb.sha256
a530f8fbb867b07aafdabf06459b2ffec5f64202a56f13bf87ca0c225b5b1189

Where could I find an md5sum or an sha256sum for the ubport-installer please?

I can't install Ubuntu Touch on my OP6T. The installer is stuck at

"Waiting for device... Fastboot is scanning for devices".

This happened after the phone became bricked as it booted and still boots with the following message:

QUALCOM CrashDump Mode
Attempted to kill init! exitcode=0x0000000b
complete_and_exit

I bricked the device after running into difficulty trying to install TWRP first:

fastboot flash recovery twrp.img
Writing 'recovery' FAILED (remote: '(recovery_b) No such partition')

Then I read https://android.stackexchange.com/questions/209673/why-cant-i-write-to-recovery-using-fastboot-on-a-b-device which advised to run instead

fastboot boot twrp.img

That is when the phone became bricked...

May I ask if Focal Fossa is working on the Meizu Pro 5? If so, should I upgrade to it or should I stay with Xenial?

@arubislander Just to clarify:

• I don't run any server. I have no network at home apart from the link between my router and my PC and UT phone. The server I was referring to belongs to the commercial email service provider and may be located in another country.
• I am not absolutely sure that the issue does not appear on my PC. It just happens that I have noticed it on my UT phone. But I think it does not happen on my PC.
• I am using µAdBlock. But is this a problem?

@arubislander Thank you arubislander and AppLee. The cracked padlock in red does not always appear like this. Most of the time it appears as a normal locked padlock in black. Here I am talking only about a single website. On my PC with Firefox under Linux, this web site appears with a normal padlock. This web site is my web mail for which I am paying a fee every year. So it is quite a serious breach of security. Could this be a hack directed against the web mail server or even a hack against my home devices?

When I visit a secure (HTTPS) website, the usual padlock in the address bar of the Morph browser sometimes appears as red and cracked. I suppose this means the connection is not secure. May I ask why and how this happens and how to avoid it?

I have lost the four digit password which must be entered after booting. This is on an old device which I haven't used for ages. It does not have any particular data that I would want to keep. So I could erase everything and reinstall the system altogether.
However I suppose I need to enable adb access before reinstalling, but I can't because I don't have the password.
So what else could I do please?

@josele13 Reinstalling Ubuntu Touch won't bring back the EFS partition which is a firmware from the manufacturer.

@josele13 Yes thanks. I had actually already tried this to no avail.

@arubislander I am on the stable channel with OTA-23. I fear that the problem has the same root as the one described in this old post of mine where it has been suggested that I might have deleted the EFS partition when I repartitioned the phone before installation. I had to repartition because I have the non-ubuntu edition of the Meizu Pro 5 with 4GB of RAM instead of 3GB.

@arubislander I have tried the WiFi scanner from the app store. It shows the name of the hotspot with the hexadecimal code in the format [XX:XX:XX:XX:XX:XX]. But the hotspot name is nowhere to be found on the list of WiFi access points on my PC.

@arubislander I have run iwlist on my PC but the name of the phone hotspot does not appear among the ESSID list.

The hotspot function is not working on my Meizu Pro 5. I have tried tos switch on and off this function, changed the hotspot name and password, and still no hotspot to be seen on my PC.

Any idea?
