How to manually upgrade from OTA-3 to OTA-4

[Mika15]

Hi everyone, I have a BQ Aquaris E5 with UBPorts OTA3, will I loose SMS, calls history and contacts if I upgrade to OTA4 ? Thanks.

@mika15 it's always a good idea to make a backup but said that, you'll keep all your data if you don't check the wipe option

[Mika15]

@advocatux Thanks for the quick response! I will do a backup before upgrading using rsync over ssh is enough as it or some procedures are better ? Other question, If I'm not happy with OTA4, is easy to downgrade or do I have to forget ? Thanks!

[advocatux]

@mika15 you're welcome. You can backup the whole /home if you want peace of mind [*] but you only need to backup the data you want to keep really.

You have the obvious things like Documents, Music, etc, that's easy to find

In ~.local/share/evolution/ you'll find the addressbook, calendar, memos, and tasks DDBB.

~.local/share/history-service/history.sqlite for SMS and calls log.

If you're using Authenticator, you'll find the config file here .config/com.ubuntu.developer.mzanetti.ubuntu-authenticator/

Probably the easier way to downgrade is to use the installer, probably switching channels will work too though.

[*] Edit to explain that if you have a complete home backup, you can easily copy to your phone any bit you could need or you forgot the first time

Thanks for this, @UniSuperBox
How long does the download take? I'm just wondering if the Snap is hanging, or whether! it's doing its thing.

@3arn0wl How long is long? About 15-20 mins all should be done.

Thanks, @Lakotaubp

Meh! It was longer than that, I think. I might just wait for OTA-5.

@3arn0wl Just restarting the installer and reconneting the phone fixed it for me when installing ubports on the nexus. Try that if you cant wait till Monday ; )

I also ran into the installation hanging after clicking "Install," even with the latest version (0.1.21-beta AppImage) of the installer. I discovered the problem, in this case at least, concerned the installer's handling of adb and fastboot. The system is intended to operate whether they are installed or not. I had adb installed, but not fastboot. Unfortunately, the fallback appears to have failed because the "platform-tools" subdirectory tree it depends on (see src/utils.js:getFallbackPlatformTools) is missing. However, once I installed fastboot, the installation did not need to fall back and it worked just fine.

@advocatux Thanks! Migration is done, my phone is working perfectly, I migrated from AppImage installer a fantastic tool, I have all my data as it was before, many thanks to the team for their work, the installer and the OS are excellent!

@mika15 kudos! Enjoy your new UT device

Unfortunately, I can't update my Fairphone 2. I have tried the update on three different systems:

1. macOS

The installer app asks in an infinite loop for the password. I have reproduced this error with a PIN and a password.

The first install didn't work either. It's a usb-c driver issue, I think.

2. Neon

I managed the first installation in Neon. The installer couldn't update the device with the following error:

I also couldn't install the recent installer. Therefore I removed the files for the installer at /opt/ and /usr/share/applications with sudo. Then I tried the installation again, but nothing happens after entering the password.

3. Windows 10

The installation app sais, that I have to reboot in bootloader but afterwards nothing happens. This application doesn't ask for a passwird.

Very frustrating user experience with UBPorts update!!

I have added some screenshots, but unfortunately they are not schon in the forum with the suggested syntax:

@marc_aurel You may want to check the method described above with system-image-cli - it is done from the phone terminal or from a computer logged into the phone via adb or ssh.

[marc_aurel]

@mihael This requires a setup for ssh, doesn't it?

It this instruction up to date? I'm not sure because of the path with the directory "phablet". I wouldn't call a FF2 a phablet.

[mihael]

@marc_aurel I don't remember if I did it this way but just connect a usb cable and then adb shell and you are inside the phone from the computer. Or just type that command for the updatr within the phone terminal app - you don't even need a computer, just the phone connected to internet.

[marc_aurel]

@mihael Thanks, this works now.

Unfortunately the settings of the new UBports still doesn't offer custom text size. This is a problem for visual impaired people. Has someone an idea, whether whis is on the roadmap?

Dekko is not working any more. Has someone a recommendation for an email app?

@marc_aurel DEKKO beta is here:

@marc_aurel BTW the password is the one of your PC, not the phone...

Hi all, short question:

if I manually upgrade to OTA-4 following the described steps, will I lose my data and apps or will they remain intact on the device after the update? Thanks.

[advocatux]

@gt you'll keep all your data as long as you don't check the wipe option.

Anyhow, if your data is important for you, you should make a backup
