Hi all, I'm doing some modifications to the ubports-installer in order to be able to manage user and system data backup and restore.

I have added a backup button on the install screen :

When you click on it you will have the following screen :

The installer will read the size of both system and userdata partition and give you an estimated sized need on your disk. You can name your backup. When you will click ok let's go, the phone will reboot into recovery and the backup will start :

At this and the phone will reboot into the OS. you will be able to find 2 tar file on your computer disk : one for the system-data, the other one for the user-data.

It is actually working fine on Meizu Pro 5.
BUT, in one of my previous thread, I had the issue that in recovery image, the user and system data partition was not mounted on /data.

In the installer code, I added for the Meizu Pro 5 the mounting of sda44 on /data/

So my questions to you are :

• Who else on different phone models have the partition /data/user-data, /data/system-data not mounted in recovery ? If that is the case, what is your partition device to mount ?
• does every one have the folder user-data and system-data in the /data folder while in recovery ?
• Are you ok with this feature or do you find it usless ?

I will now write the restore option.

@jamieweb pull it from github, here are my personal notes when I did it :

git clone https://github.com/ubports/ubports-installer.git
cd ubports-installer
npm run-script dist:linux
./setup-dev.sh
npm start

@Flohack Hi back, thanks for your answer, I finally manage to do my backup and restore with success (thanks goolge).

I share here how I did:

Backup :

#!/bin/bash
echo "Backing up your data"
adb reboot recovery
sleep 15
adb shell mount /dev/block/sda44 /data
adb shell mkfifo /backup.pipe 
adb exec-out 'tar -cvp data/system-data 2>/backup.pipe' | dd of=system.tar & adb shell cat /backup.pipe &
adb shell rm /backup.pipe
adb shell mkfifo /backup.pipe 
adb exec-out 'tar -cvp data/user-data 2>/backup.pipe' | dd of=user.tar & adb shell cat /backup.pipe &
adb shell rm /backup.pipe
adb reboot

With this script, you will mount the data partition under the recovery mode, create a pipe to transfer the content of the folder (/data/user-data) through stdout to dd on the local computer in a file named user.tar, then it will do the same for the folder system-data.

Now to restore :

#!/bin/bash
echo "Restoring your data"
adb reboot recovery
sleep 15
adb shell mount /dev/block/sda44 /data
adb shell mkfifo /resto.pipe
adb push user.tar /resto.pipe & adb shell 'cd /; cat /resto.pipe | tar -xv'
adb shell rm /resto.pipe
adb shell mkfifo /resto.pipe
adb push system.tar /resto.pipe & adb shell 'cd /; cat /resto.pipe | tar -xv'
adb reboot

This script will boot the phone into recovery mode, mount the sda44 partition into /data folder, push your backup user.tar through the previously created pipe. On the phone the pipe is catched by cat then sent to tar for decompressing.

Your backup needs to be in the same folder as the script restore because I written it like this.

Credits goes there : https://www.forum-generationmobiles.net/t78912-tutoriel-backup-adb-sauvegarde-compressee-des-donnees-de-android-vers-votre-pc-gnu-linux

I tested it and it's perfectly working, I was able to clone one of my Pro 5 to the other one Pro5.

sda44 partition is mostly for Pro5, not sure that this mount works on other model.
I hope that this could help other people.

The best way is maybe to add this feature to ubports-installer, in order to be able to just backup/restore our phone (and of course re-installing it) only with one tool.

What are you thinking about that ?

@PINE64 You mean the SanDisk flash ?

Thanks @dobey once again. I have nothing to modify in it, just trying to save time by copying a portion of existing code to create a new ListView for the VVM messages in the dialer-app, I copy the ListView from the call history and I was looking for the structure of the model.

I added a button (that will be showed only if the service is activated) on the dialer page :

That will display a new page :

I would like to display a play line when we touch the item (like the iphone style).

@ubuntoutou Ok, we progress... normaly SN should display the serial number of the phone (the one you get with adb devices. And the two line should display your WiFi mac addresses.

on my phone it give :

Mar  6 19:02:40 ubuntu-phablet kernel: [    1.246534]  [5:  kworker/u16:1:   59] [c5] @@@@ SN 860BCMSxxxxx
Mar  6 19:02:40 ubuntu-phablet kernel: [    1.246746]  [5:  kworker/u16:1:   59] [c5] @@@@ MAC 68:3E:34:xx:yy:58
Mar  6 19:02:40 ubuntu-phablet kernel: [    1.246957]  [5:  kworker/u16:1:   59] [c5] @@@@ MAC 68:3E:34:xx:yy:59

We have now to find what part of the kernel is giving thoses informations, if anybody had an idea ... you are welcome

@jamieweb Of course, no problem at all if that can help other people experiencing this with their Meizu If you need help for your script, please post in your original thread and I will try to help you. Good job.

Hi, is it possible for the further new developers who would like to start devoted on OTA to have virtual machins ready to use downloadable from ubports please ? With the official tools for ubports, I mean today we still be between old SDK (by the way it seems that the https://system-image.Ubuntu.com is not working anymore) and the atom with ubports where I found that it's difficult to find a tutorial to start a new app. if the community can simply have a downloadable VM with the dev env already setup for ubports, it can maybe help a lot of people to start helping by creating new app for our favorite OS.

I know that one VM is already made for the old sdk but how long will it be supported? I would like to implement a visual voice mail app for OTA and I don't want to have to rewrite it after 5 month for example...

@Flohack oh I was thinking that only the Meizu Pro5 was missing notifications features ! I will first modify my driver to enable the rgb function then ... I will try to take care of the API for everybody .

@stefano hi! Many thanks for your answer, I will try your solution, the phone was initially running Android, I convert it to Ubuntu 2 days after buying it. I should have the international version somewhere on my computer. I'll keep you informed.

Thanks, I will take a look at this!

You could also monitor the system dbus, sms appears in clear text on it.

Sorry I can't copy paste from terminal , maybe a bug.

sudo dbus-monitor --system "type='signal', interface='org.ofono.MessageManager'"

@ublublu you have to start the phone on bootloader usually power and vol down button hold at the same time until the scene display the fastboot message then using fastboot flash recovery [name of the recovery file]. or you can also try directly to start in recovery by holding at the same time vol up and power button. if you got the recovery screen, then start the ubports-installer. they are some thread about flashing a recovery for your phone over the net. sorry I don't have your model then I can't give you the precise procedure

@dobey hi, it is now standardized with omtp, as you can read in the link I posted before, I activate this service on my account and I receive a class 1 sms with the imap server adress, the port and the credentials. Then I configurate it inside dekko2 and I was able to receive my voice messages as an attachment in the email.

Happy to help !

@jamieweb I also had this error on Meizu Pro5, my solution was to modify the ubports-installer in order to ask the user to manually reboot the phone into recovery when this error occured, The installer wait and when your phone is in recovery, it perform the next step (downloading image and pushing it to the phone).

I can share the modified installer with you if you need.

@advocatux hi yes I can write a how to, the only things is that you will have to mount your file system in read write mode for a short time in order to activate the debug traces on ofono. ofono is actually ignoring the sms class 1 sent by the provider. I modified it in order that ofono push those sms on dbus as new signal that an application can catch. I'm waiting a new motherboard for a old meizu pro 5 to play my tests app on it before to release it..

@matteo I dind’t find Time to do it but I think the best way would be to download the kernel turbo from github, modify the driver, compil the kernel and simply copy paste the module on the device with a write fs activated. My plan was to do that like this.

@AlainW94 said in MX4 Ubuntu Edition: FAILED (remote: unknown command):

@jamieweb I perfectly understand, I modified it there is a while ... let me look for the modified file then i will post it there.

Try to replace this part of code in the file src/devices.js :

var instructBootstrap = (fastbootboot, images, bootstrapEvent) => {
    //TODO check bootloader name/version/device
    var flash = (p) => {
        fastboot.flash(images, (err, errM) => {
            if(err)
              handleBootstrapError(err, errM, bootstrapEvent, () => {
                instructBootstrap(fastbootboot, images, bootstrapEvent);
              });
            else {
              if (fastboot) {
                  utils.log.info("Booting into recovery image ALAIN...");
                  // find recovery image
                  var recoveryImg;
                  images.forEach((image) => {
                    if (image.type === "recovery")
                      recoveryImg = image;
                  });
                  // If we can't find it, report error!
                  if (!recoveryImg){
                    bootstrapEvent.emit("error", "Cant find recoveryImg to boot: "+images);
                  }else {
                    fastboot.boot(recoveryImg, p, (err, errM) => {
                      if (err) {
			utils.log.error("Fastboot: AW boot error; ");

			bootstrapEvent.emit("bootstrap:done", fastbootboot); // Ignore the error, ignore the bootstrap, boot into recovery then the installer will did the flash upload, works well on my Pro5, I only had to flash the recovery fisrt with fastboot flash recovery recovery.img, then run the installer. That's not nice I know but that worked for me.

                        //handleBootstrapError(err, errM, bootstrapEvent, () => {
                        //  instructBootstrap(fastbootboot, images, bootstrapEvent);
                        //});
                      }else
                        bootstrapEvent.emit("bootstrap:done", fastbootboot);
                    })
                  }
              } else
                  bootstrapEvent.emit("bootstrap:done", fastbootboot)
            }
        }, p)
    }
    bootstrapEvent.emit("bootstrap:flashing")
    bootstrapEvent.emit("user:write:status", "Flashing images ALAIN")
    if (!utils.needRoot()) {
        flash(false);
    }else {
        requestPassword(bootstrapEvent, (p) => {
            flash(p);
        });
    }
}

You will have to compile and install it or run it from the sources.
Good luck.

@AppLee Hi ! Maybe you can have a look to oFono, it is the app that is controlling the modem. In the documentation there is :

Flight Mode

• Flight Mode support. oFono uses the 'Online' property on the Modem interface
  that controls the state of the radio. When Online state is False, all
  interfaces that depend on the radio being on are removed. Other interfaces
  enter reduced functionality mode where only certain actions are available
  that do not depend on the radio. E.g. setting various settings on the local

You can use D-bus message for putting the radio on or off:

here you have the related d-Bus message :
https://github.com/intgr/ofono/blob/master/doc/modem-api.txt

Properties boolean Powered [readwrite]

		Boolean representing the power state of the modem
		device.

	boolean Online [readwrite]

		Boolean representing the rf state of the modem.

Online is false in flight mode.
