[Q] Resize partition cache system data - XPERIA X10 Q&A, Help & Troubleshooting

Hi there,
is it possible to change partition sizes on x10? I found some info regarding some other phones, but nothing for x10.
I also looked at the update-script of ROMs that uses xrecovery to install it, but they already start formating those partitions, not creating nor modifying their sizes; there's nothing about the mtd partition map anywhere.

[Q] 4EXT partition sizing -- insufficient information

I ran the partition alignment check and 4EXT indicated that my fat32 partition is out of alignment. The phone is working properly, so... I'm not sure if I really need to do this. Anyway, in the option for partitioning, you can either preserve the fat32 or reformat the whole card. I'm guessing that preserving the fat32 will persist the alignment issue, so a complete format is necessary.
OK...
Well, I have a problem with understanding what to do with the partition sizes. In the Info menu, I see system (789Mb), data (1.1Gb) and cache (102Mb). In the Partitioning menu all you're presented with is EXT1, EXT2, and swap. Does system=EXT1, data=EXT2, and cache=swap? Obviously those existing partitions don't fit within the presented size selections, which... brings me to my next problem.
I have a couple of backups, but now I'm wondering if I change the partition sizes, will my backups no longer work? That would be a serious drawback...
And finally... I had read somewhere a suggestion on recommended partition sizes, but I made the mistake of not saving a bookmark to it and searches aren't turning up anything. I'd greatly appreciate it if someone experienced with 4EXT partitioning could chime in here. Thanks!

Alternative to formatting data partition when installing new ROM?

I'm thinking of installing a new ROM on my phone, and I reckoned that instead of formatting the data partition, what if I just wrote a script to erase only the parts of the data partition that have been put there by the system components of the old ROM? Would that work?
If not, why?

[HELP] Link2SD. How to make it work without creating a new partition?

That.
I have an Xperia Arc S (LT18a) with a custom 4.0 ROM (Ultimate Xperia HD) and i just cant make Link2SD to recognize my 2nd partition. The classic mount: no such file or directory stuff. Which bugs me since i bought the Link2SD Pro version.
I have the normal fat32 and a ext4 partition, i've done a lot of things, created a new scrip in the .ind folder, made Link2SD a system app, rebooted, erased SD and re did partitions multiple times, it just doesnt want to work.
So i can recall couple of years ago i actually got my Moto E to work with linked folders and i never created or modified the partitions as far as i remember, so, question.
Can i link folders to install apps on sd without having to create a new partition? Because is a pain in the ass, is a slow trial and error process and im quite done after trying so much and so many different things.
Thanks
Edit. Solved. Dunno how to mark as solve it or closed so just ignore it
Solved, turned that every software **** was worthless, all i had to do was use the CWR partition tool at the recovery menu obviously and now i had correctly partitioned a ext4 partition and a fat32 one.

How I can restore partition size to original?

When i was uploading new rom, partitions connect to one. Many roms have a problems with this. Second partition has a 0MB size. I try upload stock rom by flashtool and no results. I want to restore original size. How I can do this? My phone is sony xperia lt30p.
What ROM have you flashed? Have you done a clean install, means having wiped existing Android OS before?
What's the name of the mentioned 0MB partition?
BTW:
Android comes with standard partitons as
/boot
/system
/recovery
/data
/cache
/misc
and their sizes basically are hardcoded.
Never have noticed, heard or read that when a ROM gets flashed a partition with size of 0MB will be created.
Name se

Don't confuse /sdard and sdcard.
With regards to /sdcard:
This is NOT a partition on the internal storage memory of the device but rather the ( external ) SD card.
With regards to sdcard:
This simply is a symbolic link to device's /data/media partition what is mounted as /storage/emulated/0
And How i Can restore default memory this partition? Partition with external sdcard has other name.
OK it's the partition named /data/media you're referring to.
If a partitition shows 0MB ( can't get mounted ) then this is because it probably is encrypted. Hence decrypt it. The common method is to perform a Factory Reset. If you've TWRP installed / at your fingertips then decrypting also can be done with TWRP.
This phone is other than many phones
For me, everything you post is crazy stuff: I can not understand what the problem really is.
Since Android is on the market, it has more or less the same partition layout as shown above. And I'm pretty sure your phone has this, too.
I mean about problem, when i am installing rom, show me comunicat ,,Error instaling zip file 'external_sd/android9 sony t/open_gapps-arm-9.0-pico-20201114.zip" and i wanna get rid of this problem, across restore this partition. Do you know, what i have a mean?
My last 2 cents here: Open Gapps isn't a ROM. It's merely a suite of re-compiled Google apps.
FYI: I no longer participate this thread. I hope for you others jump in.
ok, thank you for your help. Information for other people: I can't install apps on this roms, so i want to restore this partition

No system & vendor partitions in custom recoveries.

TWRP, Pitchblack, OrangeFox, whatever recovery I try, I always end up with this Super partition. And I can't see how much size it is. It's just sitting 8192MB by default.
Aren't there any recoveries that show partitions normally like system, vendor separately, with actual sizes filled ?

That's because there are no dedicated partitions for system, vendor, and product. They are all located inside one partition called "super". Think of it as one big partition that houses other smaller partitions. The size of the individual partitions is variable hence you'll only be able to see the size of the super partition.
The size of the super partition is fixed and cannot be resized after a rom is installed. The super partition was created to eliminate the need for vendors to allocate specific sizes for sub partitions. Before the super partition, each partition had to be allocated a specific size and any free memory left after writing data to it could not be used when other partitions required more space. This free space was therefore wasted.
In the super partition, the sub partitions can be the exact size of the files contained within them. Any free space is left inside the super partition and can therefore be used by other sub partitions if they need it.
Unfortunately, the biggest setback for developers is that they cannot modify the contents of sub partitions once they're made read only (usually on the first boot after installing a new rom). People who try to modify these partitions often get into boot loops forcing them to reinstall the stock rom.

Understood. But can we access /system & /vendor folders & modify files in it through root explorer.
So you're saying there's no way to remove system bloatware & unwanted apps ?

In some custom miui roms like miui eu it is possible without causing a bootloop. Sometimes a bootloop will occur because of the root explorer you use. However, of you're still on stock rom you'll very likely end up in a bootloop. AOSP roms don't have this weaknesses but they're not as stable as miui.
I recommend installing a debloated rom like MiuiMix or miui eu. Then get help from the support forums to find out how to get into system without killing the rom.
Everytime I tried to flash a ROM without wiping system (bc I can't) I got error 7. So I had to do a format data and I lost all of my stuff. Is there any way of wiping system so I don't have to do a format data?

Once after booting up any rom, check whether the device is encrypted or not. (Security > Encryption)
If it is, then offcourse, in recovery you had to wipe everything if you wanna flash a new rom. This device has dynamic partition update, that merges all OS partitions (system, vendor, product) & encrypts data partition if it's decrypted.
Ofcourse you also can't able to modify partitions while encrypted, caz you'll end up into errors.
