How to increase cache partition on Meizu PRO 5 original Flyme

Martin111

Re: How to increase cache partition ( or any partition ) on Ubuntu Touch phone? Question.

I have 1year Meizu Pro5 orig Flyme G, after complication unrooted unlocked.
The Ubuntu 15.04 (r3) installed in TWRP only from .zip file because cache for installing has only 495.9MB.

original filesystem is now :
Filesystem Size Used Available Use% Mounted on
tmpfs 1.8G 156.0K 1.8G 0% /dev
tmpfs 1.8G 28.0K 1.8G 0% /tmp
/dev/block/sda43 495.9M 432.0K 485.3M 0% /cache
/dev/block/sda44 53.5G 209.0M 53.3G 0% /data
/dev/block/sda41 2.4G 1.7G 720.4M 71% /system
tmpfs 1.8G 156.0K 1.8G 0% /system/dev

From discusion of mihael and Stefano is all understanding.

But for me nonstandard Linux user - how get fdisk command for delete custom partition and create new custom 324MB partition.
I have not on my phone -partition sda42. (which is custom partition?)
Using fdisk without experience of android partitionig can be dangerous.

Thank you for any answer.

Yes, this is the post: https://forums.ubports.com/post/6899

How can I help?

Martin111

@mihael Thanks for answer. I was detailed read.
This i can not use :
fdisk: delete the 'custom' partition (partition 42 for my meizu pro 5)
fdisk: create the 'custom' partition with a smaller size (I calculated: 512 - (700 - 512) = 512 - 188 = 324MB so that 188 would be available to add to the current size of the 'cache' partition)

I am not standrad using fdisk in LInux - Android.

How get syntax in fdisk for delete "custom" partition.
What is "custom" partition in original Flyme partitions.

Thank you

mihael

But up to that point did you follow each step? If yes, then inside fdisk type 'm' for help and it will show you what is the command for deleting a partition.

Martin111

@mihael Yes, I was see in help the possibilities of fdisk.

in this :

original filesystem in PRO5 is now :
Filesystem Size Used Available Use% Mounted on
tmpfs 1.8G 156.0K 1.8G 0% /dev
tmpfs 1.8G 28.0K 1.8G 0% /tmp
/dev/block/sda43 495.9M 432.0K 485.3M 0% /cache
/dev/block/sda44 53.5G 209.0M 53.3G 0% /data
/dev/block/sda41 2.4G 1.7G 720.4M 71% /system
tmpfs 1.8G 156.0K 1.8G 0% /system/dev

is not sda42 - where is "custom" partition?

Thank you

mihael

With sudo parted -l you can see what partitions you have...

Martin111

@mihael in using : sudo adb shell (in pro5)
parted -l (answer - not found)

advocatux

@Martin111 you run adb shell in your computer, that gets you the device shell, and then you run that command @mihael has told you (sudo parted -l)

Martin111

@advocatux in using : sudo adb shell (in pro5)
sudo parted -l (answer - not found)

I am usin Linux Mint - I hope this has no problem with linux synatax

advocatux

@Martin111 no problem at all as long as you have adb tools installed in your computer

Martin111

@advocatux how install complete adb on computer?

advocatux

@Martin111 for Linux Mint I think the name of the packages are android-tools-adb and android-tools-fastboot. Install them as you usually do.

Note: it's good to have both adb & fastboot tools if you're going to play with UT

Martin111

@advocatux I was try upade and update all system and answer is the same.
I was try it in twrp in terminal -sudo parted -l and parted -l .
The same answer.
I must go sleep. I will try discus tomorow. Tahnks for your time.

Stefano

@Martin111 I've never experienced this. That's strange not to have partition 42.
I would you advise, to go back and install 15.04 with ubuntu-device-flash tool.

First go back to TWRP and wipe it all.
Then install ubuntu-touch recovery with fastboot.
Next step is to try to install 15.04 UT with ubuntu-device-flash tool (if you running Ubuntu or Ubuntu 16.04 based distro)
Then after installing of 15.04, try again check if your partition 42 appeared.
Or
Take a shortcut and just try to reinstall the same image you are currently running with ubuntu-device-flash tool. It might fix the isue with part.42.

if none of this helps, you'll probably need to go back to Android and start from there (wipe it clean ...)

Someone with 64Gb Pro 5 could help with posting his/her Pro 5 partition table???

@druk13 nice guide, yeah, in German, but still. Hopefully that helps those guys that need to repartition theirs Pro 5.
