Is this supposed to happen or do I indeed have a corrupted directory?

I went ahead anyway and this was my result

[HACK] Grow your data partition

THE PROBLEM
As many of us have noticed, it is fairly easy to get an "Out of space" message when installing apps on our phones because, for some weird reason, Oppo decided that the storage part of the device should linger in the dark ages, when /userdata and /sdcard were separate partitions and you only had 2GB of data storage, even if your phone was a 32GB model.
Now, imagine that you are running KitKat and would like to try ART. This may be a bad idea as, if your data partition is more than 30% full, you will find that while converting your apps to this new format, Android will run out of space.
At OppoForums, a few bright people started looking into the issue and, of course, there is a way to improve the situation.
WARNING!
If you follow the steps below correctly, you should not run in any trouble. If you do not, however, you may end up spending much more time fixing your phone.
FIRST, THE THANKS SECTION
Anders tinkered with his device’s partition table until he got to where he had grown the /userdata partition to something useable. Yes, it’s some people’s definition of “play”
Jousa11 is the first person trying to put a guide together explaining the steps to reproduce Anders’ work. WARNING: I did no get to see said guide as Jousa quickly deleted it due to the risks involved. So, take that in account!
Rockman for providing the last resort rescue tools in case you brick your phone
Lucky for providing the WiFi fix
Please let me know if you are not on this list and I forgot to give you credit!
YOU WILL NEED
The hardware:
An Oppo Find5 phone(!)
A computer (Windows/Linux/Mac) with adb installed and working
A USB cable
On your computer:
adb
[Optional] fastboot
On your phone (SDCard):
parted + mke2fs + tune2fs
mmcblk0p21_persist_ext4.img
openrecovery-twrp-2.6.3.0-find5-TP-patch.img
[Optional] gdisk
You will use parted to work on your partition table; mke2fs and tune2fs to create ext4 filesystems on some of these partitions (parted does not know how to create ext4 partitions)
mmcblk0p21_persist_ext4.img is an image that you need to restore your /persist partition and avoid issues such as non-working WiFi.
openrecovery-twrp-2.6.3.0-find5-TP-patch.img is a patched recovery image. I know: you already have a recovery image if you are going through these steps. However, we are going to wipe it so you want to install this guy before rebooting. Note that if you forget, you can always flash it later using fastboot.
On your computer:
adb to access your phone recovery, push files to SDCard, reboot...
[Optional] fastboot. You will only need fastboot if you mess up your recovery partition.
WHAT IF SOMETHING GOES AWFULLY WRONG?
You may “brick” your phone. Apparently it’s near impossible to hard brick your Find5, though. See below.
First, Anders recommends making a backup of your partition table. I didn’t because I felt that if I messed something up, it would be a partitions’ content rather than the partition table but that’s not the wisest approach.
Furthermore, if you are really worried about what stilly error your fat fingers will cause (I know I should be!) you can also backup your partitions.
Backing up your partition table:
On your phone:
Code:
gdisk -b /sdcard/gpt.bin /dev/block/mmcblk0
Backing up a single partition:
On your phone:
Code:
dd if=/dev/block/mmcblk0p<partition id> of=/sdcard/backup-<partition id>.bin
On your computer:
Code:
adb pull /sdcard/gpt.bin
adb pull /sdcard/backup-<partition id>.bin
LAST RESORT
OK. So, you've bricked your phone. Now what?
First, you will need Windows. So if you're on a Mac or Linux and have no access to a Windows machine/VM, er..don't brick your phone.
- Download drivers and tools
- Download and follow the instructions
READY ? LET'S GET STARTED
>>>>>>>>>>>> First, Download The Files <<<<<<<<<<<<
Then...
On your computer:
UPDATE As dixxa pointed out, mke2fs and tune2fs may already be present on your device. It was not the case for me but you should check first; it seems like a good idea to use existing binaries.
Code:
adb reboot recovery
adb push parted /sbin
adb push mke2fs /sbin
adb push tune2fs /sbin
On your phone:
Code:
chmod 755 /sbin/parted /sbin/mke2fs /sbin/tune2fs
umount /cache
umount /sdcard
umount /emmc
umount /data
parted /dev/block/mmcblk0
You are now in the parted shell.
CAREFUL! Do not delete any partition below 20 or you will enter "Big Oops" territory. I recommend typing carefully and, yes, staying away from copy/paste operations that may swallow a character like, say, the '2' in '20'
Note that the size value I am using here is '4GB' for /userdata (rather than 2GB). I guess you could make /userdata bigger than 4GB, in which case you would have to recompute all the offsets in the commands below(!)
Code:
# rm sdcard
rm 29
# 28 thru 23 are reserved
rm 28
rm 27
rm 26
rm 25
# rm recovery
rm 24
# rm misc
rm 23
# rm cache
rm 22
# rm persist
rm 21
# rm data/emmc
rm 20
# now, re-create partitions but data is bigger
mkpart primary 1325 5421
name 20 userdata
mkpart primary 5421 5430
name 21 persist
mkpart primary 5430 5967
name 22 cache
mkpart primary 5967 5968
name 23 misc
mkpart primary 5968 5979
name 24 recovery
mkpart primary 5979 6012
name 25 reserve1
mkpart primary 6012 6019
name 26 reserve2
mkpart primary 6019 6028
name 27 reserve3
mkpart primary 6028 6062
name 28 reserve4
mkpart primary 6062MB 100%
name 29 sdcard
# exit parted shell
q
Let's create a file system on the partitions that require one. Note that I am formatting the SDCard using VFAT as, yes, EXT4 is a better FS, but it is also incompatible with Oppo's ROM and some apps may not require the proper permissions etc.
Code:
# Notes:
# -m 0: no reserved blocks
# -c 0: no max mount count
# -C -1: no mount count
# -i -1: max_int interval between checks
mke2fs -t ext4 -m 0 -L userdata /dev/block/mmcblk0p20
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p20
mke2fs -t ext4 -m 0 -L persist /dev/block/mmcblk0p21
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p21
mke2fs -t ext4 -m 0 -L cache /dev/block/mmcblk0p22
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p22
# Hey look it’s an ext4 SDCard!
mke2fs -t ext4 -m 0 -L sdcard /dev/block/mmcblk0p29
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p29
# Actually to avoid errors like unable to write to root of sdcard:
mkdosfs -n sdcard -F 32 /dev/block/mmcblk0p29
mount -t vfat /dev/block/mmcblk0p29 /sdcard
At this point, we have clobbered the /persist partition and this could cause issues as mentioned earlier. Let's restore it.
Code:
# Restore /persist partition
mount -t ext4 /dev/block/mmcblk0p29 /sdcard
# On computer
adb push mmcblk0p21_persist_ext4.img /sdcard/
# On phone
dd if=mmcblk0p21_persist_ext4.img of=/dev/block/mmcblk0p21
IMPORTANT! Flash your recovery partition now. If you wait until after rebooting, you will need to use fastboot instead.
Code:
# Recovery partition: on computer
adb push openrecovery-twrp-2.6.3.0-find5-TP-patch.img /sdcard/
# On phone
dd if=openrecovery-twrp-2.6.3.0-find5-TP-patch.img of=/dev/block/mmcblk0p24
Admire your work
Code:
parted /dev/block/mmcblk0 print
Reboot into your new recovery and install your favorite ROM

You should probably use the latest TWRP 2.6.3.1 found here: http://techerrata.com/file/twrp2/find5/openrecovery-twrp-2.6.3.1-find5.img

Looks good to me. Just be very carefully doing this.

gdisk -b /sdcard/gpt.bin /dev/block/mmcblk0
those commands need to be typed in recovery even that one ?

Yes although I imagine this particular command should also work when booting system.

This thread is fine the only problem here is with those 2 binaries: mke2fs and tune2fs
You don't need to push them or chmod them since they are already in the recovery
Except that that thread is perfect.

Since we're at toying with partition, can't we merge the partitions in some way ?

Just wondering is there any way to build a script to do this in an automated way thus avoiding user errors and typos?

There is a thread on the oppo forums
http://www.oppoforums.com/threads/guide-resizing-internal-storage-on-find-5-32gb.8361/
Hello everyone,
is the guide for the 32 or 16 gb model?
I have 16 gb Oppo find 5.
Thanks.
PS: what "on your phone" is supposed to mean"?

If you don't know what does that mean don't do it you'll screw your phone.

hi
Please would you make something like this for oppo find 7a x9006?
thanks

Anyone willing to recompute all the offsets dor just one 16gb partition?

Hi all, I am trying to do this mod and I am half way through it with a problem
I am stuck on the new file system, I cannot use mke2fs or tune2fs, i get
Code:
mke2fs: not found
like it doesn't even exist, but it does I can see it. I get the same error for tune2fs. but parted and gdisk work fine.
Yes I did push them and chmod 755 them.. and I have tried running it from the /sbin directory.
Help!

Hello!
I'm getting the same error over and over again creating /dev/block/mmcblk0p21 to /dev/block/mmcblk0p22:
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p21
"Bad magic number in super-block while trying to open /dev/block/mmcblk0p21"
"Couldn't find valid filesystem superblock"
So i can't create a file system on the created partitions. I have been looking everywhere for an answer. Somebody have an idea?

U should just wait. Andrew dodd found a way to make find7a have unified partition and he claims he can make it work on find5 as well. Let's give him a bit to figure it out tho.
Scribed henceforth from thy G pad.

Gdisk not working...
Ok guys sort of a noob here... Firstly, totally appreciate what you guys are doing here... I wants it bad, thass why i'm here.
So far... I have i have done...
"adb reboot recovery"
"adb push gdisk /sbin"
I figured that's how you are supposed to install it ... hope i'm not wrong, but i guess it pushed through fine
But after rebooting to system in TWRP , i opened terminal emulator and when i use the command
"gdisk -b /sdcard/gpt.bin /dev/block/mmcblk0"
I get ...
"/system/bin/sh: gdisk: not found"
now i'm too scared to proceed without backing up the partition tables... so please help...
edit - FYI , i'm running the last build of Asylum Carbon... should i just go back to latest oopo stable stock rom and then root my device again and then try all this again... would that help... ???

Directly from Andrew Dodds g+ " IT HAS BEGUN.
The first phase of Find 7a/7s LVM testing is here.* See linked post for details.* (Sorry to disappoint, but the first phase is "make sure we don't break existing configurations")
Once this phase is complete, the remaining list is:
Fix up the remaining TWRP issues (make RECOVERY_SDCARD_ON_DATA runtime instead of compile-time)
Make user-friendly conversion processes
Once things are solid on Find 7, I'll work on Find 5 and N1."
Stay thirsty my friends. Good things ahead

Does this work for the 16gb model?

Can someone help please?
I'm trying to do this, but after enter in parted [parted /dev/block/mmcblk0] when i try to do "rm 29", i get "can't remove 29: no such file or directory
I'm doing the "on your phone" commands in TWRP command line., is that correct?
I'm running stable colorOS 1.0.9i

Finally I finish the process.
My notes:
Goal:
Keep my current system intact (stable colorOS 1.0.9i , because i have no patience to format, install a new ROM and reinstall/recofigure everything
So I backup everything on phone with TWRP and I push sdcard content (wich include the system backup i made) with ADB
1 - If I push mke2fs and tune2fs IT WILL NOT WORK. I flash the last find 5 recovery (openrecovery-twrp-2.8.1.0-find5.img) and I dont push or chmod anyting, parted, mke2fs, tune2fs are all already in the recover and that's the only way I could run mke2fs and tune2fs
edit: 1.5 - The phone commands had to be enter via ADB shell. In TWRP command line, after you enter in parted it will not accept commands.
2 - To "rm 29", i had to "umount /dev/block/mmcblk0", otherwise "rm 29" fail due to partition in use
3 - after this instruction:
mount -t vfat /dev/block/mmcblk0p29 /sdcard
(the last one on the 4 block of code)
We have this:
# Restore /persist partition
mount -t ext4 /dev/block/mmcblk0p29 /sdcard
This instruction was the only one that give me a error, so I move to the next ones.
The error was that the partition was busy, what makes senses because in the last instruction we mount the same partition on the same folder but with different file system!!??
So I move to the next instruction. I have no idea if it's a instructions mistake but it looks like, because it says "# Restore /persist partition" but the command has nothing to do with /persist
4 - FINISH
5 - Reboot in recovery. Push sdcard backup to /sdcard. restore system backup with TWRP restore
Voila, my phone exactly as before but with 3,76GB for APPS. Finally!!! The "running out of space" message on a flagship quad-core 2GB RAM phone!!!!!!?????? Was driving me CRAZYYYYY

Thanks Fickx for the up to date information, I just did my re-partition successfully, here's what I did:
- Use Rashr update the recovery to twrp-2.8.1.0
- reboot into recovery
- connect to PC (Make sure adb works, "adb devices")
- on PC:

How to fix bad Superblocks ?

Hello,
I have an Iconia A200 that I tried to flash with the latest Imni-Rom 4.4.4 .
So far I had a lot of obstacles cause of missing Knowledge, but status is now:
- Bootloader CWM 6.045 installed and unlocked
- Had issues with formatting/mounting, but fixed.
- Flashed Omnirom, but it doesnt boot up -> Unable to purge /Data
Now I cannot 'use' the Data Partition.
I tried the codeblock this Codeblock via ADB:
Code:
1) mke2fs -j -b 4096 /dev/block/mmcblk0p8
2) tune2fs -O extents,uninit_bg,dir_index -C 1 /dev/block/mmcblk0p8
3) e2fsck -fy /dev/block/mmcblk0p8
The first Command i had to repeat 20 times, cause it always stopped at
Code:
'Writing inode tables: 72/224'
The second Command does not work.
The third says me:
Code:
Code:
e2fsck 1.41.14 (22-Dec-2010)
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/block/mmcblk0p8
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
When i try the -b Option the result is the same.
Do I have bad Blocks in the internal Memory?
Any chance to fix this?
Thanks!

[GUIDE][WORK IN PROGRESS]Oneplus one - resize system partition and maybe even more

WARNING!!!​Everyone is responsible for the proper functioning of their device. This guide is the result of personal experiments and I'm not responsible for any damage caused to your device as a result of improper use of its contents.
Introduction
Stock partitions layout has a 1.3Gb /system partition that is too small for users that flash modern custom roms + some kinds of google apps.
This is a step by step guide to change the layout of the partitions table with a bigger /system partition.
How
On OnePlus One, stock partition table looks like the following
Code:
... ... ...
/dev/block/mmcblk0p14 : start= 294912, name="system"
/dev/block/mmcblk0p15 : start= 3006464, name="persist"
/dev/block/mmcblk0p16 : start= 3072000, name="cache"
... ... ...
/dev/block/mmcblk0p28 : start= 4521984, name="userdata"
/dev/block/mmcblk0p29 : start= 121552896, name="grow"
With this layout, resizing the /system partition may seem difficult because it's close to other very important partitions.
So I've experimented with another approach. By resizing userdata partition, and relocate the /system partition at the beginning of the resulting free space, other partitions are left untouched.
There are mainly two (little) issues
almost all custom roms out of there assume that /system partition is 1.3gb of size
on internal storage the old area of /system partition are unused.
For the first point, the solution is to resize the filesystem when you first flash a custom rom. To automatically resize filesystem at every update there is an addon.d script.
For the second point the new free space available (the old 1.3G /system partition) can be used as a new /cache partition.
And, again, the new free space available (the old /cache partition) can be the famous /vendor partition (that is out of the scope of this guide).
This guide uses the sfdisk tool from util-linux. In my opinion, it's more powerful than parted and it's easy to use via script.
IMPORTANT - Before you start
Obviously, this method is destructive regarding userdata partition, so make a full backup of your data.
Manually resizing filesystem of /system partition is needed only once because the addon.d script will ensure that everything works as expected. The only exception is when you wipe /system and flash a new rom
Prerequisites
a working TWRP recovery installed on device
knowledge of adb tools
a statically cross compiled sfdisk tool (you can self compile, or use the one attached below)
this addon.d script (thanks to @osmosis)
flashable zip of a custom rom (and optionally gapps, magisk etc etc etc)
flashable zip bacon-resize-system.zip (attached on this post)
Let's go
enter TWRP recovery and connect phone on a PC
push sfdisk into a temporary dir and ensure is executable
Code:
adb push sfdisk-arm /tmp
adb shell
cd /tmp
chmod 755 sfdisk-arm
make and pull a backup of your partition table (there is also the 64Gb stock layout in attachments)
Code:
./sfdisk-arm -d /dev/block/mmcblk0 > bacon.gpt
exit
adb pull /tmp/bacon.gpt
looking into the partition table you see that userdata partition starts at sector 4521984.
So in order to resize partition (for example 53G instead of 55,8G).
Code:
adb shell
cd /tmp
umount /data
umount /sdcard
echo "4521984,53G" | ./sfdisk-arm --no-reread -N 28 /dev/block/mmcblk0
. Scrolling down the output of this command the new userdata partition is
Code:
Device Start End Sectors Size Type
/dev/block/mmcblk0p28 4521984 115671039 111149056 53G unknown
so the start sector of /system partition will be 115671040 (115671039+1)
relocating system partition at the end of the new userdata partition(size now will be 2,8G)
Code:
echo "115671040,+" | ./sfdisk-arm --no-reread -N 14 /dev/block/mmcblk0
reboot recovery (kernel need to reload partition table)
Code:
reboot recovery
format userdata with TWRP(no wipe... full format)
push custom rom with adb and flash with TWRP (without rebooting)
flash bacon-resize-system.zip
finish.. you can now reboot or continue with flashing gapps, magisk etc etc (but now with a bigger system partition)
Rollback
TODO
Nice to have
flashable zip for addon.d script (WIP)(DONE)

[*] looking into the partition table you see that userdata partition starts at sector 4521984.

If I understand correctly, the system partition will now be 2.8 GB larger. So it will have a total of about 4.1 GB. Is that so?
BTW this is very good work. :good::good::good::good:

the /system partition are 'moved' at the end of the resized userdata partition.. so it's only 2.8G
I've made this decision for two reasons
no needs to move critical partitions
the unused space (the old /system partition) can be used in another way(for example a larger cache partition or a vendor partition)

EDIT: another reason for this method is that almost all custom roms works

I have one small problem. Internal storage (/sdcard) I haven't defined. Is it defined as "Invalid partition selection." Full storage is for /data.
How I can mount /sdcard?
Edit: I mean this: /sdcard, /storage/emulated/0, /data/media/0
I changed partition system to ext2 in TWRP.
And system partition si bigger. This works.
Edit2:
I have problem with flash new ROM. Flashing change filesystem from ext2 to ext4 always with smaller previous value. I have problem maybe with script. But I try it again tomorrow.

after formatting /data the filesystem is empty.. these directories are created when you first start android(if not found)

This is normal. Starting from nougat/oreo the building process of an android system creates a block-based flashable zip.
This means that the system partition is preformatted in ext4 and (for Oneplus One) with a size of 1.3G (the original /system partition). So you cannot change the type of filesystem.

Check if the script has the right permission (I'll update the guide).
Also keep in mind that, like others addon.d scrips, it works only with the OTA updater.
If you flash directly from recovery (changing rom, or dirty flash) you need to manually repeat the steps described for resizing partition and installing the script.
I've planned to create a flashable zip to automate these steps.
Thanks
Michele

little update... I've uploaded a simple flashable zip that resize filesystem of /system partition and install the addon.d script.
The procedure now is more simpler.

Hi ilmich, I followed your guide while flashing LOS 17.1 on my OPO and this allowed me to have a /system partition large enough to be able to have a large GApps installation, so cheers for that! However, I installed an OTA update on LOS 17.1 today (29/10 update) and that rebooted to TWRP which seemed to have installed the zip, but then entered a boot loop with several "Could not find x for ctl.interface_start" on the dmesg log. I can see the resizesystem script in the addon.d folder but something must've gone wrong because the partitions seem to have been restored to its default and /system seems to be 1.3GB again in TWRP. I will pull the partition table and post it here.
Update:
I was wrong, /system seems to be the same size on running sfdisk. The cause of the update fail must be somewhere else. Here's the /system partition from sfdisk:
Code:
/dev/block/mmcblk0p14 : start= 115671040, size= 5881856, type=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7, uuid=B17FA16F-3B1D-8D12-329D-88B49B096554, name="system", attrs="GUID:60"
I still don't understand why TWRP displays /system as 1303MB again though. Any idea?

Still working...?
Are you still working on this guide?
I'ld love to try it, but I'm a little frightened since there seem to be issues about future udates of Lineage (see previous post).

Sorry for the late reply. For sure, but for now, I don't have with me my opo.
But if I understand correctly

update problems are not the repartition procedure.

I suppose that TWRP is built with 1.3Gb size limit (like everything that is based on opo device tree) and without mounting the filesystem show this static value.
But the power of this procedure (and the resize script) is that you can safely install your preferred rom. The filesystem is expanded in order to fill the 'new' partition size.
During my experiments, I've updated a lineage os (also simulating OTA by pushing a recovery command into the /cache partition), with and without GAPPS.
This guide, if executed step by step, should be safe.

I'm testing again my procedure. This is my situation
Code:
bacon:/ $ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/block/mmcblk0p14 2.7G 1.0G 1.7G 38% /
/dev/block/mmcblk0p28 52G 15G 37G 30% /data
I've latest official lineageos with some Gapps.
Now I'm waiting for an official OTA to see if anything goes wrong.

Hi all,
I've uploaded a new bacon-resize-system.zip that fixes the issue with OTA (wrong escape sequence when creating survival script in the updater binary).
Thanks all for the bug report.
Cheers
Michele

Hello sir,
I am still using OPO in 2021 and i want 5gb system partition.. What will be start and end sectors for that changes? I am really confused so can you please recreate your post for 5gb and will you post it in reply?
Another one question if i flashed stock rom via fastboot then it will restore partition size to default or changes still remain which we did?
Thank You.

Am I right for 4.8gb??
Please answer of this 2 questions
1. If i flashed stock rom via fastboot then it will restore partition size to default or changes still remains which we did?
2. It is necessary to flash bacon-resize-system.zip everytime whenever we flash new custom rom or after ota updates?
Thank You.

Introduction
Stock partitions layout has a 1.3Gb /system partition that is too small for users that flash modern custom roms + some kinds of google apps.
This is a step by step guide to change the layout of the partitions table with a bigger /system partition.
How
On OnePlus One, stock partition table looks like the following
Code:
... ... ...
/dev/block/mmcblk0p14 : start= 294912, name="system"
/dev/block/mmcblk0p15 : start= 3006464, name="persist"
/dev/block/mmcblk0p16 : start= 3072000, name="cache"
... ... ...
/dev/block/mmcblk0p28 : start= 4521984, name="userdata"
/dev/block/mmcblk0p29 : start= 121552896, name="grow"
With this layout, resizing the /system partition may seem difficult because it's close to other very important partitions.
So I've experimented with another approach. By resizing userdata partition, and relocate the /system partition at the beginning of the resulting free space, other partitions are left untouched.
There are mainly two (little) issues
almost all custom roms out of there assume that /system partition is 1.3gb of size
on internal storage the old area of /system partition are unused.
For the first point, the solution is to resize the filesystem when you first flash a custom rom. To automatically resize filesystem at every update there is an addon.d script.
For the second point the new free space available (the old 1.3G /system partition) can be used as a new /cache partition.
And, again, the new free space available (the old /cache partition) can be the famous /vendor partition (that is out of the scope of this guide).
This guide uses the sfdisk tool from util-linux. In my opinion, it's more powerful than parted and it's easy to use via script.
IMPORTANT - Before you start
Obviously, this method is destructive regarding userdata partition, so make a full backup of your data.
Manually resizing filesystem of /system partition is needed only once because the addon.d script will ensure that everything works as expected. The only exception is when you wipe /system and flash a new rom
Prerequisites
a working TWRP recovery installed on device
knowledge of adb tools
a statically cross compiled sfdisk tool (you can self compile, or use the one attached below)
this addon.d script (thanks to @osmosis)
flashable zip of a custom rom (and optionally gapps, magisk etc etc etc)
flashable zip bacon-resize-system.zip (attached on this post)
Let's go
enter TWRP recovery and connect phone on a PC
push sfdisk into a temporary dir and ensure is executable
Code:
adb push sfdisk-arm /tmp
adb shell
cd /tmp
chmod 755 sfdisk-arm
make and pull a backup of your partition table (there is also the 64Gb stock layout in attachments)
Code:
./sfdisk-arm -d /dev/block/mmcblk0 > bacon.gpt
exit
adb pull /tmp/bacon.gpt
looking into the partition table you see that userdata partition starts at sector 4521984.
So in order to resize partition (for example 53G instead of 55,8G).
Code:
adb shell
cd /tmp
umount /data
umount /sdcard
echo "4521984,53G" | ./sfdisk-arm --no-reread -N 28 /dev/block/mmcblk0
. Scrolling down the output of this command the new userdata partition is
Code:
Device Start End Sectors Size Type
/dev/block/mmcblk0p28 4521984 115671039 111149056 53G unknown
so the start sector of /system partition will be 115671040 (115671039+1)
relocating system partition at the end of the new userdata partition(size now will be 2,8G)
Code:
echo "115671040,+" | ./sfdisk-arm --no-reread -N 14 /dev/block/mmcblk0
reboot recovery (kernel need to reload partition table)
Code:
reboot recovery
format userdata with TWRP(no wipe... full format)
push custom rom with adb and flash with TWRP (without rebooting)
flash bacon-resize-system.zip
finish.. you can now reboot or continue with flashing gapps, magisk etc etc (but now with a bigger system partition)
Rollback
TODO
Nice to have
flashable zip for addon.d script (WIP)(DONE)

I'm interested in installing Ubuntu touch on my OnePlus One but since I used this guide successfully to resize my system partition I don't think I can install it without restoring the partition tables. How can I restore the partitions properly without bricking my phone?

have you figured it out?
i was succeeded, through
Failed to mount '/system' (invalid argument)
i have seen also.
i was able to sideload lineage and boot it.
After rebooting into recovery the error message was away.
After that i sideloaded lienage again, then bacon-resize-system.zip.
After that i was able to sideload Gapps Nano, the required size check was successful
Oh wait, you have OPO Phone, not OnePlus One
you can try to restore your partiotion table from backup created earlier
Bash:

[TUTORIAL] How to resize system partition on Galaxy S3 for larger GAPPS

On newer Android versions, the system occupies more of the system partition and with GAPPS upgrades, larger GAPPS packages (such as stock and mini) cannot fit on the system partition of the 2012 Galaxy S3. You can just use pico or nano, but sometimes you want the full GAPPS, the real deal. This is also necessary for upcoming ROMs that come with GAPPS preinstalled, such as Pixel Experience. To do this, you must resize the system partition. You can do this by taking some of the space from the cache partition and giving it to the system partition.
PLEASE NOTE: This process is not risk-free! If you do not know what you are doing, I strongly advise against this procedure. I am not responsible for any bricked devices or issues you may face. You have been warned.
Requirements:
A Samsung Galaxy S3. I have the i9300 model, where I have tested it.
parted, downloadable from here. If it downloads as a txt file, delete the extension by renaming it without the txt.
TWRP installed on your device (available for i9300 from here.)
A computer with ADB installed and relevant drivers.
First of all, you must boot TWRP. Once booted, wipe all partitions in TWRP, including system. Reboot back into recovery. Then go into mount and deselect all devices, and uncheck the box saying "Mount system partition as read-only"
Secondly, connect your S3 and send parted to the device with the following command:
Code:
adb push <path_to_parted> /
Thirdly, enter the ADB shell with the following command:
Code:
adb shell
Now, give executable permission to the parted file with the following command:
Code:
chmod +x parted
Now run:
Code:
./parted /dev/block/mmcblk0
Run the print command and you will get a list of partitions. It should look something like:
Code:
Model: MMC VTU00M (sd/mmc)
Disk /dev/block/mmcblk0: 15.8GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 4194kB 8389kB 4194kB BOTA0
2 8389kB 12.6MB 4194kB BOTA1
3 12.6MB 33.6MB 21.0MB ext4 EFS
4 33.6MB 41.9MB 8389kB PARAM
5 41.9MB 50.3MB 8389kB BOOT
6 50.3MB 58.7MB 8389kB RECOVERY
7 58.7MB 92.3MB 33.6MB RADIO
8 92.3MB 1166MB 1074MB ext4 CACHE
9 1166MB 2777MB 1611MB ext4 SYSTEM
10 2777MB 3364MB 587MB ext4 HIDDEN
11 3364MB 3372MB 8389kB OTA
12 3372MB 15.8GB 12.4GB ext4 USERDATA
Make a note of the Start and End points for partitions 8 and 9 (CACHE and SYSTEM). In my case, the start and end points for partition 8 are 92.3 and 1166 and the start and end points for partition 9 are 1166 and 2777.
What we're going to do is delete these two partitions, then recreate them, but make the new partition 8 (Cache) smaller and allocate the space left to partition 9 (System).
Remove them with the following commands in parted:
Code:
./parted /dev/block/mmcblk0 rm 8
./parted /dev/block/mmcblk0 rm 9
Now recreate them with the following commands:
Code:
./parted /dev/block/mmcblk0 mkpart primary <cache_start> <cache_start+200>
./parted /dev/block/mmcblk0 mkpart primary <cache_end> <system_end>
Replace <cache_start> with the start of the former cache petition. In my case, it would be:
Code:
./parted /dev/block/mmcblk0 mkpart primary 92.3 292
./parted /dev/block/mmcblk0 mkpart primary 292 2777
Now name the partitions.
Code:
./parted /dev/block/mmcblk0 name 8 CACHE
./parted /dev/block/mmcblk0 name 9 SYSTEM
Then format them as ext4:
Code:
mke2fs -T ext4 /dev/block/mmcblk0p8
mke2fs -T ext4 /dev/block/mmcblk0p9
Run ./parted, followed by print, to check if the changes have been applied. If so, well done! You have successfully enlarged the system partition. Exit parted with the quit command.
Now configure and exit:
Code:
mount -a
exit
Reboot back into recovery and install any ROM of your choice. Once you've installed the ROM, reboot into recovery once again, and navigate to wipe --> advanced wipe, select system, tap repair or change filesystem, then resize.
You can now install any GAPPS of your choice. I've gotten LineageOS 16.0 working with mini gapps (Google Play Store + some Google apps) and it is working fine. You could make the system partition bigger by borrowing some more MB from the cache partition, or experimenting further by taking some from the HIDDEN partition. Remember, I am NOT responsible for any damage done when doing this. You assume full responsibility for any problems with the device. I hope this tutorial did help you, feel free to post here if it did or ask for help if you need it.

Did you experiment this process for a long time ? With so small a cache what could be the consequences ?
A finally do you know what is the use of HIDDEN partition ?
Great tutorial anyway.

Newer Android versions don't use up as much in the cache partition. If you're on say stock ICS or JB you may encounter some issues but if you're using LOS 15 or 16 it should work fine. I've used LOS 16 with GAPPS using this method for a while on my S3 and it's been fine.

Cheers for that. I've been trying for some time to do the same thing on a Galaxy S4 Mini, working from a few variations of this process that I've found here and there, but never with any success. All appears to go well, with no errors, but it doesn't stick--the device just reverts to the previous partition sizes on reboot..
I've been using parted 3.2. I wondered if it would work with the parted you were using, but the one from your new link is 1.8 and doesn't even get as far for me (tried that one previously and it gets errors on my device).
If anyone know how to overcome the issue of resized partitions not surviving a reboot on Android, please help! I've been unable to solve it.
If it was plain Linux, it would be something to do with fstab, but fstab is never mentioned in the posts where people succeed in resizing Android partitions, so I think it must be something else, and perhaps something that varies from one device to another. Looking forward to any suggestions--thanks!

Can this idea/technique be applied to other *droid based devices
like Nook HD ?
