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

[mihael]

From terminal even...

I don't know... Mine shows

/dev/disk/by-partlabel/cache     679M  768K  664M   1% /android/cache

@mihael for some reason it did not change/save even after I saved id with w and rebooted and formated the cache ???

But when I saved it the table was this:

SO WHAT NOW, WHY IT DID NOT SAVE???

[mihael]

I'm sorry, I really don't know... Maybe it's some linux issue that someone with more experience could shed light upon...

[mihael]

What does df -h from twrp console show?

[Stefano]

@mihael Did you do it on the phone TWRP terminal or via adb? I mean the whole repartitioning. Cos I have used adb shell for it.

[Stefano]

@mihael /dev/disk/by-partlabel/cache 496M 4.2M 482M 1% /android/cache

[mihael]

@Stefano I believe I did it through ssh...

[Stefano]

@mihael I give it a try again later, maybe I'll figure it out. (will try with TWRP terminal as well)

[mihael]

Let me know...

[Stefano]

@mihael I managed to do it. The problem was that I did not format the newly created partitions properly and did not change the names of them as I did not seen such an option in fdisk , but, there is an expert menu under ,x, and there is option to rename. After I renamed it, I format it and now it shows partition 43 = 723m, so I think that should suffice. Will try now to flash 16.04 now, we'll see what happens now! Thank you a lot for your help.

Edit. It flashed 16.04 without failing in recovery

@Stefano Wonderful!!! Thank you too for all your posts!
