Need help to flash Meizu5 pro originally on Android. Problem with the cache partition
-
@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 which ones? the keyring and image-master files?
-
@mlinodasilva yes
-
@hans1977se alright, decompressing the version1.tar.xz yields these files:
720.0 # tree . |-- system | `-- etc | |-- system-image | | |-- channel.ini | | `-- config.d | | |-- 00_default.ini -> ../client.ini | | `-- 01_channel.ini -> ../channel.ini | `-- ubuntu-build `-- version-1.tar.xzas for the keyring file:
729.0 # tree . |-- device-60f53a5768e9340729d3a5ef9263bd3a9726792e7d0dbf830e5b124938dd419a.tar.xz |-- device-60f53a5768e9340729d3a5ef9263bd3a9726792e7d0dbf830e5b124938dd419a.tar.xz.asc |-- keyring-4c4e7ef380ebcfa2c31084efa199138e93bfed8fc58aa3eb06bdf75a78af9b57.tar.xz |-- keyring-4c4e7ef380ebcfa2c31084efa199138e93bfed8fc58aa3eb06bdf75a78af9b57.tar.xz.asc |-- system | `-- usr | `-- share | `-- system-image | |-- archive-master.tar.xz | `-- archive-master.tar.xz.asc |-- ubports-d50c18b27590af5734a826c4f7857d8909b0e0f902d21af142a780620c8eb58b.tar.xz `-- ubports-d50c18b27590af5734a826c4f7857d8909b0e0f902d21af142a780620c8eb58b.tar.xz.ascIn 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 Disk /dev/block/sda: 7633920 sectors, 29.1 GiB Logical sector size: 4096 bytes 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 Total free space is 11386 sectors (44.5 MiB) Number Start (sector) End (sector) Size Code Name 1 1024 1279 1024.0 KiB 0700 private 2 1280 1343 256.0 KiB 0700 proinfo 3 1344 1407 256.0 KiB 0700 misc 21 2048 3071 4.0 MiB 0700 param 22 3072 5119 8.0 MiB 0700 efs 23 5120 5631 2.0 MiB 0700 pnv 24 5632 6655 4.0 MiB 0700 ldfw 25 6656 7679 4.0 MiB 0700 dtb 26 7680 13823 24.0 MiB 0700 bootimg 27 13824 22015 32.0 MiB 0700 recovery 28 22016 30207 32.0 MiB 0700 bootlogo 29 30208 35327 20.0 MiB 0700 rstinfo 30 35328 40447 20.0 MiB 0700 mnv 31 40448 45567 20.0 MiB 0700 reserved1 32 45568 50687 20.0 MiB 0700 reserved2 33 50688 55807 20.0 MiB 0700 reserved3 41 65536 720895 2.5 GiB 0700 system 42 720896 851967 512.0 MiB 0700 custom 43 851968 983039 512.0 MiB 0700 cache 44 983040 7633914 25.4 GiB 0700 userdata -
@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. ThenHope it works. ( I did once the same time when I had a similar problem and then it all works like a charm) Fingers crossed.
-
@mlinodasilva if you search xda site for multirom v33 ,there is a link for all the bits and pieces of pro 5 (when using fastboot i always have to use sudo , or nothing happens)

This post is deleted! -
@mlinodasilva Just try to restore that backup of mine and let me know how it did go.
-
@Stefano That worked thank God!! I had an additional difficulty the recovery couldn't flash the data partition for some reason so I reformated it, I suspect the issue might have been lying there. For the sake of it I tried ubuntu-device-flash and it still didn't work, but this time he got stuck on a progress bar.
Anyway I flashed all the partition images you sent me, and soon enough I had ubports booting!
I cannot state how much I am grateful for your help, you have been most kind in helping me, I was going nuts oer this. THANKS!
Now I just have to figure out how to make my SIM work again (I never could get it to work in anything else than the slim slot with the canonical image, and now it doesn't seem to recognize the sim in any of the two slots, but thats probably an hardware fault I have had since the beginning, these meizu 5 phones are known to have random hardware issues).
In any case, I have internet, camera, and hopefully GPS already working, so it's already a nice start. Thanks again Stefano!
-
@mlinodasilva Very nice indeed, that @Stefano was able to help you to get ubports onto your phone!
I'm thinking that it is probably not only you having this problem so now when you have both his working files and your non-working files in the cache, could you try to compare to see if you can find something that looks wrong about them? In particular the files keyring and image-master files that looked strange in your log print would be interesting i think.
-
@hans1977se I can upload my /root/.cache/ubuntuimages I haven't deleted it yet, would that be of interest?
-
@mlinodasilva Sure. Why not. More people will be able to compare then. Could be a good idea to limit the size if there are obviously unrelated files, though.
-
Update: Don't try to rsync your old canonical home folder in ubports, everything gets stuck, I'm in the middle of wiping my data folder and reflashing again
It's gonna be a pain in the ass re-importing the contacts, calendar, etc... is there a list of the relevant hidden folders anywhere?
-
@mlinodasilva Copy the .local/share/history-service/history.sqlite, the .local/share/evolution/addressbook/system/contacts.db and your camera pictures. Should take you quite a step, hopefully.

@mlinodasilva I would wipe all partitions apart from ExternalSD ( not rm -rf, but wipe in setting of TWRP)
Then I would do fastboot -w, reboot to recovery,
then I would flash Flyme - the one you flashed when converting from a to i/g firmware. IT might show some errors, but it will flash successfully.
Unlock the bootloader if it gets locked again.
Start the Flyme, enable the Developer options + Usb debbuging.
Reboot to fastboot, flash TWRP recovery.
Reboot to recovery, wipe ( not rm -rf ) all partitions apart from ExternalSD.
Now reboot to fastboot and flash recovery-turbo.img
Reboot to recovery
In terminal type: adb devices if it list your device.
Now try ubuntu-device-flash..... again. -
@Stefano this is to try to solve the issue
With the phone not detecting the SIM card? Did anyoneelse have this issue in the past? -
@mlinodasilva What happened that your phone doesn't recognise sim cards? In settings, are there an IMEI numbers or is it says None?
This might help to fix the issues with the partitions on your phone, since you have some glitches there, so maybe a complete wipe + factory reset + flashing Flyme and later Ubports might be a sollution.
Not sure about the recognising the SIM, but give it a shot. -
@mlinodasilva I forgot to tell that rsync between my Nexus 4 with Canonical image and Nexus 5 with ubports image works for me.
-
Heh, it seems I have a string of bad luck regarding this phone (in between the hassle it was getting it from China, then flashing canonical ubuntu, then breaking the screen, trying to get a replacement one, the ubports).
I tried anther chip and it works, so for some reason my SIM is malfunctioning, will get a replacement one...
I've been slowly reinstalling stuff, I noticed that the GPS has trouble working, although it seems to be recognised, but I remember it was already difficult when indoors during the days of canonical. Accelerometer works, but the compass app doesn't seem to be working. Minor hurdles...
Anyway, by request I uploaded my ubuntuimage folder from /root/.cache the link is below:
