Hoping someone from the dev thread
reads this. Only reason I can't post there is I am "new".
I'm running into an issue booting using the alternate boot option.
My primary boot is Stock rooted 6.3
My alternate is Pure AOKP ICS with Hashcode 3.0 Kerne
This is my partition table.
Code:
~ # parted /dev/block/mmcblk0 print
parted /dev/block/mmcblk0 print
Model: MMC MMC08G (sd/mmc)
Disk /dev/block/mmcblk0: 7818MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 131kB 262kB 131kB xloader
2 262kB 524kB 262kB bootloader
3 524kB 11.0MB 10.5MB dkernel
4 11.0MB 212MB 201MB dfs
5 212MB 229MB 16.8MB recovery
6 229MB 296MB 67.1MB ext4 backup
7 296MB 307MB 10.5MB boot
8 307MB 312MB 5243kB splash
9 312MB 849MB 537MB ext4 system
10 849MB 2241MB 1392MB ext4 userdata
11 2241MB 2369MB 128MB ext4 cache
12 2369MB 5750MB 3381MB fat32 media msftres
13 5750MB 5761MB 11.0MB boot2
14 5761MB 6298MB 537MB ext4 system2
15 6298MB 7690MB 1392MB ext4 userdata2
16 7690MB 7818MB 128MB ext4 cache2
This is from my init.omap4430.rc file
Code:
on fs
log "== init.omap4430.rc: on fs ------------------------"
mount ext4 /dev/block/mmcblk0p14 /system wait ro
mount ext4 /dev/block/mmcblk0p15 /data wait noatime nosuid nodev errors=continue
mount ext4 /dev/block/mmcblk0p16 /cache wait noatime nosuid nodev errors=continue
mount ext4 /dev/block/mmcblk0p8 /dropbox wait noatime nosuid nodev errors=continue
And this is my update-script
Code:
format("ext4", "EMMC", "/dev/block/platform/mmci-omap-hs.1/by-name/system2", "0");
mount("ext4", "EMMC", "/dev/block/platform/mmci-omap-hs.1/by-name/system2", "/system");
......
package_extract_file("boot.img", "/dev/block/platform/mmci-omap-hs.1/by-name/boot2");
The install works fine, and everything seems to go to its correct place. But when I select the alternate boot option it sits indefinitely on the selection screen.
What recovery are you using? Many people are reporting that ClockworkMod seems to have trouble with ROMs using the 3.0 kernel, making them unbootable even on a stock boot layout. TWRP doesn't have issues with it, so I would try that if you're currently using CWM.
If that's not the issue, then try using the "/dev/block/mmcblk0p#" style to specify the partitions in the updater-script. I had some difficulty getting it to play nicely with the "by-name" style for whatever reason, especially with the boot images (I'm not really sure why, though).

I'm used TWRP 2.0 and 2.1, neither "worked".
The rom installed, that doesn't seem to be the issue, unless I am completely off base.
I was unable to install gapps because moding its install script to goto the mmcblk0p14 caused it to fail, I think it was because it was signed, and I modded it making the md5 invalid. I need to work on that, but that shouldn't cause an issue with booting.
The only thing I can think of is that your boot2 is on p16 while mine is on p13?? would that be the issue?
Changed to
Code:
format("ext4", "EMMC", "/dev/block/mmcblk0p14");
mount("ext4", "EMMC", "/dev/block/mmcblk0p14", "/system");
.......
package_extract_file("boot.img", "/dev/block/mmcblk0p13");
and
Code:
on fs
mount ext4 /dev/block/mmcblk0p14 /system wait ro
mount ext4 /dev/block/mmcblk0p15 /data wait noatime nosuid nodev errors=continue
# mount ext4 /dev/block/platform/mmci-omap-hs.1/by-name/cache /cache wait noatime nosuid nodev errors=contin$
mount ext4 /dev/block/mmcblk0p8 /dropbox wait noatime nosuid nodev errors=continue
This time I am trying to put the 6.3 rooted version on the alternate.
The install occurs with no issue. It just gets stuck at the Alternate Boot menu.
I'm using 0.1, not sure if there is another version of the loader.
Hi there
Is there anyone can mod the Custom Recovery for Korean S3 (E210L) ?
here is the partition info: (different for international version on block numbers)
/dev/block/mmcblk0p10 /system
/dev/block/mmcblk0p13 /data
/dev/block/mmcblk0p9 /cache
/dev/block/mmcblk0p3 /efs
Since the gapps for 4.4 need very much space wee need bigger system partitions.
I've created a script which automates this process and increases them both to 840MB.
the space is taken from the userdata partition.
You should backup your whole phone before doing this(storage will not be touched but you shouldn't take the risk)
I tested it with 32GB version only so if you want to know if it will work for 16gb, too give me the output of this command:
parted -s /dev/block/mmcblk0 print
Download:
http://d-h.st/FWz
Instructions:
1) boot into CWM
2) adb push repartition.sh /tmp
3) adb shell chmod 0777 /tmp/repartition.sh
4) adb shell /tmp/repartition.sh
5) adb reboot recovery
6) now you can do all the usual stuff like enabling TDB and installing ROM's
Sounds great but I cannot test it, since I dont have any parted binaries (at least in my 4.1.1 Wajk Wiui ROM) ? Can you please tell me where I can get them.
Second Question:
Im currently running TDB:
System 1 latest WIUI 4.1.1 v5 ROM
System 2 MIUI v6 1.9.19
Both system partitions are completely full (usage 98 %) and the same with the data partitions ( usage 97 % )!
Would it be possible to decrease /sdcard space and repartition it like the following with TDB enabled:
system 800 mb
system1 800 mb
data 1500 mb
data1 1500 mb
sdcard *the rest*
thanks in advance
sounds like you tried to repartition from Android
You need to boot to CWM - you have parted there.
Sorry I hate people who just ask stupid questions before reading the instructions carefully ...silly me sorry for that...
What about the second question, is it possible to either increase the data partitions for less space on /sdcard ?
there isn't sth. like a data1 partition. we have one data partition only that's why we need the TDB hack.
other than that it's possible but you should backup all your data and restore it afterwards.

Ok got it.
So following your instructions and editing script like the following should work ?
Code:
change_table() {
ui_print "parted: delete"
parted -s /dev/block/mmcblk0 rm 23 || return 1 # system
parted -s /dev/block/mmcblk0 rm 24 || return 1 # system1
parted -s /dev/block/mmcblk0 rm 25 || return 1 # cache
parted -s /dev/block/mmcblk0 rm 26 || return 1 # userdata
parted -s /dev/block/mmcblk0 rm 27 || return 1 # storage
ui_print "parted: create"
parted -s /dev/block/mmcblk0 mkpartfs primary ext2 336MB 1176MB || return 1
parted -s /dev/block/mmcblk0 mkpartfs primary ext2 1176MB 2016MB || return 1
parted -s /dev/block/mmcblk0 mkpartfs primary ext2 2016MB 2419MB || return 1
parted -s /dev/block/mmcblk0 mkpartfs primary ext2 2419MB 6515MB || return 1
parted -s /dev/block/mmcblk0 mkpartfs primary ext2 6515MB 31.3GB || return 1
ui_print "parted: name"
parted -s /dev/block/mmcblk0 name 23 system || return 1
parted -s /dev/block/mmcblk0 name 24 system1 || return 1
parted -s /dev/block/mmcblk0 name 25 cache || return 1
parted -s /dev/block/mmcblk0 name 26 userdata || return 1
parted -s /dev/block/mmcblk0 name 27 storage || return 1
return 0
}
Code:
ui_print "format partitions"
for NUM in 23 24 25 26 27
do
if ! format_partition "$NUM"; then
ui_print "Failed format partition $NUM"
exit 1
fi
done
already did full backup of sdcard, i just dont know if i should disable TDB before i stat repartitioning ... I dont know how TDB works to split the data partition thats my problem :/
yes that should work.
You don't need to disable TDB because your whole data partition will be wiped and it stores the TDB configuration(that means that TDB automatically gets disabled).
Had some errors but now its working fine ..thanks
unmount sdcard in CWM. It's a bug of this script.
Nice to hear it works now.
7 days ago Phone not start because partition corrupt
Hello
First do not panic is not the fault of your script but for you experience with mi2s and partitions are the few people in the world that can save my phone.
I'm playing a game phone(Xiaomi m2s 16GB) hang and one or more partitions are corrupt (I think this is the problem). But all de documentation than i find to delete o edit partition not work. Fastboot rom installation all ok but always only start with white logo. Mirecovery works perfectly and CWM by ivan works but temporally with this command sudo fastboot boot recovery.img
This is the result of your script

Can you explain a little more? Does it only leave 1 system partition? Can I flash it like a regular zip?
Enviado desde mi MI 2S mediante Tapatalk
any step by step manual how to change partition? with all necessary downloads etc...
or.... is it possible to delete system2 with all its parts? - for me I'd to use system1 only
Why can not I change the size of the system partition?
Already tried several times, with disabled TDB and with enabled TDB.
Full wipe did and still no result.
P.S. I have already been able to do any repartitioning.

UPD. The problem was that I was using Windows Povershell
Run the script from the command line and everything turned out.
Thanks!
I have to format first system and system1 in recovery to apply this script, because I have and error :
tmp/repartition.sh lin 115 can´t create /sdcard/parted_12_06_2014_FDFD6F4CB043F4956D9CAD053C3738AA.
DO MOUNT your SDCARD
then Follow the instruction
duhh...
I modified the script a little bit for 1 ROM usage. System1 is 840MB as in the original and System2 is 5MB. The rest goes into userdata. This is for the 16GB version.
Ok! I did again and umount the sdcard abd it worked fine.
Thanks
I found a better way
If u reboot into dload mode, u can change the partition table from your computer
The problem is that most partition managers don't support changing the GPT Partition names and that's why I added support for that to GParted.
GParted supports booting from Live CD/USB so Windows/Mac users aren't left out.
http://i.imgur.com/3SwSXs2.png
I pushed the patch to GParted repo's and I'll inform u once there're any news.
from my point of view the best way for use is:
- system (system1) - let 1024 MB
- system1 (system2) - let 10 MB
- userdata (apps) - let 4096 MB (take it from sdcard) - but maybe more
Hi guys, I'm a new poster but long time reader of these boards, which helped me a lot since I got my A500 and an Android phone years ago. So far I've always found a ready solution for my 'droid needs and wants here but this time I think I've hit a bricked (tablet) wall! :laugh::crying:
My A500 has Skrilax_CZ's bootloader v9 with CWM v6.0.4.5 on the secondary partition and for more than a year has been running HenrikE's Android 4.4.4 (OmniROM unofficial) from this thread: http://forum.xda-developers.com/showthread.php?t=2705989 The ROM has been going fine apart from a few random freezes but overall I like it.
Yesterday I was using the tablet to read a book and it started running Play store auto updates, I went to look at the store app to check which apps etc, then switched back to my book and the tablet froze. Normally I'd just long press the power button and then press it again to turn it on, so I did, only this time the ROM would not boot anymore and the tablet got stuck at the bootloader screen. I went into recovery and wiped cache and dalvik, no change. I went back to recovery and then I realized the partitions aren't mounting nor can be formatted! /system, /data, /cache, nothing:
E: format_volume: make_extf4fs failed on /dev/block/mmcblk0p3
Without much hope I reinstalled the ROM with a data/factory reset and that of course didn't fix it. Tried to erase userdata and cache with fastboot, no change. It looks like either my internal SD card is broken/not found or my partitions are horribly corrupted? mmcblk0 isn't showing on /dev, see below from adb shell:
/dev/block # ls
loop0 loop2 loop4 loop6 mmcblk0p5 zram0
loop1 loop3 loop5 loop7 vold

/etc # mount -t ext4 /dev/block/mmcblk0p8 /data
mount: mounting /dev/block/mmcblk0p8 on /data failed: No such file or directory
/etc #
Looking at other threads I guess the next step would be to try an APX reinstall however I use Linux and don't have a Windows machine around. While I can certainly spend my Easter break setting up a Windows Virtualbox :crying: do you guys think this is a hardware fault or something that can be fixed? Many thanks for any input. Oh and yeah I do have the tablet's SBK number.

Hi all, I've narrowed it down to a bad sector on the tablet's internal storage and posted on this older thread about the same problem http://forum.xda-developers.com/showthread.php?t=1691729&page=5

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

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.

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.
