          Thanks for the SP Flash Tool link, I will check it out. I'm confused about your first link though, you linked me to a website related to BQ products although I'm trying to get a fix for my Meizu phone?

          EDIT: Apparently the SP Flash Tool does not support the Meizu Pro 5 (only the MX4 appears on the list) so we're back to square one 😕

          EDIT2: Sorry I wasn't using the correct version, I'm checking SP Flash Tool and it seems to be the way to go. However, I do need the "scatter file" for the Meizu Pro 5 ubuntu edition, which will be used to change the phone partitions. A 15min check over the internet yielded no results so far... If someone can help with this, it would be very much appreciated.

          EDIT3: Can't get a scatter.txt file. I think its time to go back to android. This phone is unusable right now with the canonical ubuntu version, nothing is working (sim not registering, most of the apps crash, etc...). Maybe I will check again some months from now if someone found a way to install ubports on those Meizu Pro 5 that were originally shipped with the android 495MB cache partition. 😕

            @mlinodasilva How interesting. I have an Android version and had no problems to flash either Canonical or Ubports version on it.
            Had acctually another one Android version and also no problem to install.

            Make sure when flashing to clear recovery folder as if there is no room, the flash will fail.

            Device/cache/recovery and delete all inside of that folder.

              Here is the dump from when I try to flash ubports:

              503.0 # ubuntu-device-flash --server=http://system-image.ubports.com touch --device=turbo --channel=15.04/stable --bootstrap --recovery-image=recovery-turbo.img

              Can't boot recovery image
              

              Each time I have wiped the cache folder using TWRP, so for me it is a mystery why other people like you can successfully flash an android meizu pro 5 but not me.

              My problem was that I flashed canonical image on a stock chinese android meizu Pro 5, after changing the firmware to international, etc... Then at some point I broke my screen and it took me a few months for getting a new one. When I came back, canonical had discontinued ubuntu touch and ubports was just starting. When I couldn't flash my phone two months ago I figured I would wait for the community to have improved tools, but it seems I'm not yet there, so I think I migth have something strange going on over my partition structure although I never did touch them (so this should be the same stock android partition system.

              The only thing I found out about the scatter file is that it is supposed to be the mediatek MT 6795 scatter file, but the only thing I found on the web was this link for flashing android: http://flashromandroid.top/2017/03/4767-simple_step_flash_android-meizu-pro-5.html

              Again, I am simply not familiar at all with the concept of scatter files, which is why I thought about asking for help here. Unfortunately it seems I have a very specific issue with my phone though, so it's a bit frustrating on my end :).

                @mlinodasilva It can't be Mediatek scatter file when Pro 5 has a Samsung Exynos processor.
                Maybe if you, from TWRP recovery wipe all, then reboot to fastboot mode and type: fastboot -w,
                then reboit to TWRP recovery and maku sure you have a update.zip on your ExternalSD and flash an Android Flyme international version, the one with unlocked bootloder( the same one when you have done it for the fist time).
                Then normally boot it, make sure developer option is selected, usb debbuging.
                Reboot to TWRP and wipe it all completely.
                Then flash Ubuntu recovery-turbo.img via fastboot and flash Ubports again.
                I would not use the option bootstrap, it never worked for me, nor the recovery addition.

                  @mlinodasilva try to flash the recovery-turbo.img first and then just reboot to recovery and flash it without the bootstrap and recovery additios. It has to work!

                        @mlinodasilva I think those semi-secret Canonical partner devices seem to have some extra snags, but i have had the same problem as you on my Nexus 4. For me deleting all in .cache/ubuntuimages and install again solved the issue. You could try that unless you get any better device specific instructions here.

                          @mlinodasilva Have you flash the recovery-turbo.img downloaded from Ubports site?

                          Try again, install TWRP recovery, wipe it all clean, install recovery-turbo.img again.

                          Go to your Home folder on PC, enable to view hidden files, go to .cache/ubuntuimages and delete all folders from there.

                          Then try again to flash it like before without bootstrap and recovery option.

                            Allright, this is turning to be quite the challenge...

                            The recovery image I'm using is the one from ubports (as in the short tutorial to flash the Meizu Pro 5):
                            wget http://cdimage.ubports.com/devices/recovery-turbo.img
                            check.

                            The TWRP image I'm using TWRP_3.0_m86_patched_st0rm77
                            link here: https://forum.xda-developers.com/meizu-pro-5/development/recovery-twrp3-0m86patchedst0rm77-t3469296
                            check

                            Now I'm doing this exact procedure when I start again:

                            fastboot flash recovery TWRP_3.0_m86_patched_st0rm77.img
                            fastboot reboot
                            #I switch to TWRP
                            adb devices #I check that phone is visible
                            adb push recovery-turbo.img /sdcard/
                            #I switch to TWRP and flash the .img in the recovery (not system) partition
                            #I reboot to recovery mode and have the ubuntu logo with the wine color background
                            ubuntu-device-flash --server=http://system-image.ubports.com touch --device=turbo --channel=15.04/stable
                            

                            And then once the procedure I posted previously completes I have the error screen when I reboot the phone.

                            Now regarding the cache clearing that you guys suggested, I couldn't find any .cache folder. I tried to look with TWRP and using adb from my laptop. No can do.

                            I'm putting some info about my filesystem in hopes that it can shed some lights to some of you guys who know better

                            PS: BTW: I'm flashing my phone as root from my laptop since otherwise adb doesn't recognise the phone, I'm assuming this is not a problem correct?

                            PS1: In TWRP I can do an advanced wipe of the following partitions:
                            Dalvik/ART Cache
                            Cache
                            System
                            Data
                            Internal Storage
                            Micro SDCard
                            USB OTG

                            Which ones should I try wiping? I'm a little weary of doing anything harsh for fears of bricking the phone...

                              Edit as a way of a new post since akismet flags my edits as spam???

                              Now regarding the cache clearing that you guys suggested, I couldn't find any ubuntuimages inside the /system/root/ .cache folder. I used adb shell ls -la /system/root/.cache.

                              BTW I never posted the link discussing the android vs. ubuntu devices partitions, it may come in handy as a reference for this device: https://forum.xda-developers.com/meizu-pro-5/help/meizu-pro5-32gb-64gb-partition-tables-t3460085

                              EDIT: flashed again the recovery image then did ubuntu-device-flash after wiping cache and system through TWRP -> Advanced wipe and I still get the Update failed message.

                                @mlinodasilva It's the cache on your pc that you should delete. In your case /root/.cache/ubuntuimages since you install as root.

                                  @hans1977se oooooh I see.

                                  It didn't work though. After flashing I got the same error screen, see below the steps I made:

                                  (removed because Akismet still flags this as spam will try to repost separately)

                                  It did re-download the packages from the remote server but apparently this was not enough

                                      @mlinodasilva It still looks like a possible problem with the cache, I think, but also it would be nice to know what is in the 991 bytes file and the 992 bytes file. It might be that it contains "Invalid request", or something, which would mean that you don't have access to all the files before you install.

                                      So, i think you should check the content of those two small files and try one more time to clear the cache. I.e: rm -fr /root/.cache/ubuntuimages/.

                                            @hans1977se alright, decompressing the version1.tar.xz yields these files:

                                            as for the keyring file:

                                            In any case couldn't it be possible to manually download the kernel files and flash them like I did originally for the canonical ubuntu-touch? I used the method from this link: https://askubuntu.com/questions/767323/how-to-install-ubuntu-on-meizu-pro-5-that-was-originally-with-android

                                            I would need a kernel-OTA-15.zip (with boot.img, dtb, logo.bin, ldfw), ubuntu*.tar.xz, device*.tar.xz, custom*.tar.xz, version*.tar.xz. Basically doing whatever worked in the past with canonical...

                                            Anyway, there seems to be nothing wrong with my partition table as shown by the command below...

                                            746.0 # adb shell sgdisk --print /dev/block/sda | grep -v GUID

                                            Partition table holds up to 128 entries
                                            First usable sector is 6, last usable sector is 7633914
                                            Partitions will be aligned on 64-sector boundaries

                                              @mlinodasilva Ok, let's try something else here.
                                              Install TWRP recovery, wipe it all clean, download my backup of Ubports_ota1.zip from : https://drive.google.com/file/d/0B1z6xtxx8BDjVFQ4czZmbzhwWjg/view?usp=sharing
                                              unzip it, and restore it with TWRP.
                                              It's a fresh, clean, formated install of Ubports_ota1. Then just flash recovery-turbo.img. Then

                                              Hope it works. ( I did once the same time when I had a similar problem and then it all works like a charm) Fingers crossed.
