Nexus 7 (2013) Repartition
No one is responsible for your actions except yourself. Everything written further may potentially brick your device, although risk is reduced to minimum.
This repartition package offers 1.5G /system; a /vendor partition and it is fully backward compatible with any ROM (including stock system.img).
Known-issues
HTML:
- If repartition pack says that device isn't correct,
than, if partition table wasn't modified before,
congrats! your device has different memory chip
that those I worked with. No worry, PM me and
I'll add support for it.
DO THE BACKUPs. Repartition will erase all your data
USB connection to PC is MANDATORY else you will not have opportunity to push ROM to your device
Backup
# Before processing further we highly recommend you backup persist and EFS using adb
# Or you might lose your IMEI/WIFI + BT mac addresses
Code:
adb root
adb shell
dd if=/dev/block/mmcblk0p2 of=/sdcard/modemst1.img
dd if=/dev/block/mmcblk0p3 of=/sdcard/modemst2.img
dd if=/dev/block/mmcblk0p4 of=/sdcard/persist.img
Now you can find 3 *.img files at path /sdcard. Copy them to your PC since internal memory will be erased.
Installation
HTML:
# This mod is backwards compatible with any ROM so we highly recommend NOT to reverse it if repartition went well.
# You should use ONLY recovery from this thread since other don't support all benefits of this mod.
# When installing ROM just after you flashed zip and before installing GAPPs you MUST make a resize in TWRP since all roms are build for ~800M system.
# Package is unified for flo and deb. To restore stock layout use same zip and steps as for repartition.
1. Boot into recovery (You need to allow system partition modification to be able resize /system in recovery).
2. Backup your data & Move your files from flash to your PC.
3. Flash repartition pack zip.
4. Do the actions asked by repartition pack (go to Terminal in ordinary recovery and input word that pack will tell you. Everything else will be done automatically).
5. Phone will reboot into recovery.
6. Install TWRP from below (it is build with support of new partitions layout and sizes. It can be differed from official TWRP by next format 3.x.x-1 UA).
7. Format everything. (mount errors will not affect formatting!)
- In TWRP: Wipe > Format data
- Type yes
- Once this completes go to: Wipe > Advanced Wipe
- Tick all the boxes and wipe. There should be no further mount errors. (Thanks [user=7694808]@mr_rubbish[/user] for corrections in formatting).
8. Install ROM which you like.
9. Enjoy better flash partition layout.
If something gone wrong - we recommend you NOT to do anything by yourself. Write here for help, else you may do only worse.

Common issues and F. A. Q.
Repartition pack should be safe for most devices. Common mistakes, issues and their solution will be published here.
1. You shouldn't flash any internal parts of repartition pack (*.sh files) only flash whole zip using TWRP. You may use my scripts for personal use or projects but authorship should to be kept.
2. If something isn't mounting after repartition try to format partitions that don't mount using Wipe -> Advanced Wipe in TWPR. Ideally you should format in that way all partitions in Advanced Wipe menu (see 5-th step of installation guide).
3. If you want to be sure that repartition went well I enclose loging zip. Flash it after repartition (when device reboots into TWRP). It won't modify anything only generates a partition.log in root of internal storage and outputs your current partition layout to screen. You should check if your layout is same as those fragments I provide under spoiler (file systems doesn't matter). If there are any differences you have to describe what you did and enclose partition.log to your post.

...
30 2348843008B 2610987007B 262144000B vendor
4. After flashing most ROMs system size will reduce to stock, you need to resize /system in TWRP or use flashable resize zip for ROMs that support addon.d (automatic resize when dirty flashing updates).
5. After returning to stock partition table you won't be able to get into the Recovery from the bootloader anymore, but when you start the tablet normally it goes straight in the Recovery. It is normal state. New partition table proposes larger /recovery size (16MB) while stock gives only 10MB. During restoring stock process, it is impossible to restore larger recovery backup into new smaller partition. Whether not to leave user without recovery excess, recovery backup restores into /boot partition. Just flash ordinary TWRP and install ROMs from it.
6. Don't install the zip file from the USB OTG. Copy them into the /sdcard. Else you will get message after flashing repartition pack.
Code:
"Can not extract updater-script. Do you have it in package?
Updating partition details...
...done"

@rlw6534 should be fine now
Any chance you give details on backing up persist and EFS with dd command? I'm not really a noob but I also don't want to mess up my tab...
@rlw6534 You actually should't brake anything. Added an instruction how to backup EFS and persist.
OK. Tried to flash on a clean, freshly wiped system (Flo 32G), all stock, ext4 on cache and Data, TWRP 3.2.3-0. Got the following:
******Applying dark magic******
This is not a Nexus 7 (2013)
Updater process ended with ERROR: 1
How to restore files, that we copied from our tablet using dd command ? (I haven't done anything yet. Just asking)
Sent from my whyred using XDA Labs
@rlw6534 your partition table was modified.
@MikiGry same commands, just switch paths.

Do you mean that despite this error message:
******Applying dark magic******

Updater process ended with ERROR: 1
The partition table has been modified correctly?
@lollyjay No it wasnt. Package has 2 step security system. It checks if partition table was modified and in what way (by package itself, by user or it is stock). Second step is that package itself doesn't modify anything, it needs manual confirmation in terminal, else no changes will be applied.

I have previously used sysrepart.zip and sysrepartundo.zip from this thread, although not recently:
https://forum.xda-developers.com/showpost.php?p=76278047&postcount=19
I returned it to stock a while back (827MB). Perhaps I need to sgdisk a stock partition table?
@rlw6534 Every manual repartition or repartition made not by my pack needs an individual look and partition table restore.

OK. Here is my partition layout. My userdata appears to be smaller than stock, but there isn't enough room on mmcblk0 to increase it to the size that your script is looking for. I have no idea how that could have been changed without bricking the tab. Everything else looks normal. Ideas?

With the advent of Blackrose custom HBOOT which gives us S-OFF, we can now resize the MTD partitions of our N1. This method is the one used by lbcoder in the Desire thread where you patch the recovery and boot in order to pass modified MTD partition information which supersedes the one provided by the SPL. Using this, I've managed to increase my userdata partition by ~50 MB by taking ~50 MB from the cache partition.
These instructions are for advanced users only. This will involve hex calculations and command line instructions that are not for the faint of heart. I don't believe it's dangerous though so anyone could still try since I will try to make these instructions as detailed as I possibly can.
What you need:
N1 with Blackrose HBOOT (I'm not sure this is needed though after I read more in-depth about the patch)
hex calculator (or a pencil & paper if you want to do it manually)
adb
fastboot
unpack-bootimg.pl
mkbootimg
recovery.img <- in my case I used ClockWorkMod 5.0.2 from here
boot.img <- taken from CM zip (in my case my KANG)
Partition Layout:
0x000003ee0000-0x000003fc0000 : "misc"
0x000004240000-0x000004640000 : "recovery"
0x000004640000-0x0000049c0000 : "boot"
0x0000049c0000-0x00000dac0000 : "system"
0x00000dac0000-0x0000139c0000 : "cache"
0x0000139c0000-0x00001fe00000 : "userdata"
Partition Sizes in Hex:
0x0000000e0000 : "misc"
0x000000400000 : "recovery"
0x000000380000 : "boot"
0x000009100000 : "system"
0x000005f00000 : "cache"
0x00000c440000 : "userdata"
Step-by-step Instructions:
A>Backup your current system: (OPTIONAL)
*I'm assuming you're using CWM 5.0.2 for the backup step since I tried using 3.X and the restore didn't work
1.) Boot your N1 into recovery using either adb reboot recovery or through the bootloader
2.) Backup your current system (I'm going to assume you know how to use your recovery for this)
B>Calculate new MTD parameter values:
*For this example I'm going to transfer ~50MB of cache space to my userdata partition:
1.) Since I know the cache partition is ~100MB in size, I'll just divide the hex size in 2:
0x5f00000 / 2 = 0x2f80000 <= this will be our new cache size
**Note that there is a minimum of 0x20000 (128k) for a partition and the size must be divisible by it which is why I'm playing safe and just dividing the original number in order to get an easier value for this example.
2.) Add the new cache partition size to the original cache partition starting address to get the new starting address of the userdata partition:
0xdac0000 + 0x2f80000 = 0x10a40000 <= this will be the new starting address for userdata
3.) Get the new userdata size by subtracting the new starting address of userdata with the ending address:
0x1fe00000 - 0x10a40000 = 0xf3c0000 <= this will be the new userdata size
C>Create a new recovery.img file which uses the new values:
1.) Breakdown the recovery.img file into it's kernel and ramdisk components using unpack-bootimg.pl:
.\unpack-bootimg.pl recovery.img
*This will yield 2 files and 1 directory. You can delete the directory since we only need the files.
2.) Rename the kernel from the recovery.img-kernel.gz made from unpack-bootimg.pl to recovery.img-kernel.
3.) Create the recovery-new.img file using mkbootimg with the new MTD command embedded:
mkbootimg --cmdline 'no_console_suspend=1 console=null mtdparts=msm_nand:[email protected](misc),[email protected](recovery),[email protected](boot),[email protected](system),[email protected](cache),[email protected](userdata)' --kernel recovery.img-kernel --ramdisk recovery.img-ramdisk.cpio.gz -o recovery-new.img --base 0x20000000
*Note that the values for cache starting address, userdata starting address and userdata size have been changed to the newly calculated values in the previous step.
**This will yield recovery-new.img which will be used in the next steps.
D>Create a new boot.img file which uses the new values:
1.) Breakdown the boot.img file into it's kernel and ramdisk components using unpack-bootimg.pl:
.\unpack-bootimg.pl boot.img
*This will yield 2 files and 1 directory. You can delete the directory since we only need the files.
2.) Rename the kernel from the boot.img-kernel.gz made from unpack-bootimg.pl to boot.img-kernel.
3.) Create the boot-new.img file using mkbootimg with the new MTD command embedded:
mkbootimg --cmdline 'no_console_suspend=1 wire.search_count=5 mtdparts=msm_nand:[email protected](misc),[email protected](recovery),[email protected](boot),[email protected](system),[email protected](cache),[email protected](userdata)' --kernel boot.img-kernel --ramdisk boot.img-ramdisk.cpio.gz -o boot-new.img --base 0x20000000
*Note that the values for cache starting address, userdata starting address and userdata size have been changed to the newly calculated values in the previous step.
**This will yield boot-new.img which will be used in the next steps.
E>Flash the recovery-new.img:
1.) Boot into bootloader and use fastboot command to flash the new recovery:
fastboot flash recovery recovery-new.img
F>Make system operational:
1.) Boot into recovery mode.
2.) Erase everything (factory reset)
3.) Either:
- Flash the ROM you took the original boot.img from OR
- Restore the backup you made previously (this only works (or has been tested) on CWM 5.0.2)
4.) DO NOT REBOOT YET!!!
G>Flash modified boot.img:
1.) Use adb to reboot to bootloader directly from recovery: (this is for safety since if you boot from an unmodified boot.img you'll have to start from F again.
adb reboot bootloader
2.) Use fastboot to flash the new boot image:
fastboot flash boot boot-new.img
3.) You may restart normally.
For those who've read this far, everything above has been rendered obsolete! Here's an editor for the SPL itself for the partition sizes:

*Instructions are in dla5244's thread 2nd post.
Try it at your own risk though!

2 Questions:
Is the userdata space where downloaded apps go?
why didn't you choose any other partition to transfer empty space from?

1.) Yes.

thank U. Now I have no need to buy a new phone because of constantly running out of memory
Does it mean that every time I flash a new kernel, the whole effort will go waste?
Also, can I use the same procedure for Amon RA recovery??

For that you need to do only steps D, F and G. If you flash only a kernel which uses koush's anykernel updater, you don't need to do anything.

One more silly question
Will the following procedure work.
1. Flash any ROM.
2. Then flash the modified boot.img (which may not belong to that ROM).
3. Then optionally flash the desired kernel.

Yeah. That would work since you're replacing the kernel anyways. What's important is that the kernel is compatible with the ROM.
Well done IR cannot wait to resize my data partition..
Okay, I extracted the recovery.img file, now when I try to extract recovery.img-kernel.gz, it gives the following error: not in gzip format. Exactly same happens for boot.img. I tried extracting it with different extractors on windows and ubuntu, nothing worked. Pls help.
I don't like using MTD because over time you will notice lag. If your already using sd-ext then your data is basically not being used. And I believe that cache never gets past 50% usage. Just putting in my two cents

Found the problem. It seems it was never compressed in the first place. Ark sees this and just copies the file without the .gz extension.
*Instructions edited accordingly.
I may sound a bit noobish, but I'm facing one more hindrance:
How exactly do I run the mkbootimg file in the ubuntu terminal? I mean, can you give me the exact syntax?
I was facing a similar problem with the perl script, but then I found a solution on google, but didnt find anything for the mkbootimg. Can I run it under windows cmd?

Wait, I found it. It's a bug. Thanks! I'll edit it when I get home. For now, please double check the values by reopening the made file before flashing. If the values are incorrect, please DON'T FLASH!!!

DISCLAIMER!
Operations on phone’s partition could be EXTREMALY dangerous.
As You surely expect - I take no resposibility if something will go... not as it supposed to. The responsibility for potential damages caused by using this guide is Yours, and Yours only!
New system partition scheme is “designed” for custom ROMs NOT based on original Samsung firmwares (because of it’s size and using /preload partition, which we intend to extremely resize), to name just a few reasons).
The method of modification is created by @Tesla-MADAL93 from Galaxy Advance sub-forum, all credits should go to him!!! He spend many hours using trials and errors method to achieve final success.
Part ONE: Preparations / theory.
1.Procedure requires any Linux distro with usb connection configured (tested on Ubuntu 12.04 LTS).
2.Working ADB (android debug bridge) – you don’t need to install whole ADK, just adb file with correct path added.
[EDIT/CAUTION]You can use Windows with adb configured, as proven by @maxprzemo, but I wasn’t tested by author of this guide!
3.It is strongly recommended to make a backup of your apps and data before start (using titanium backup or simipar app) Restoring nandroid backup will destroy your new partitions, so don’t use it!!!
4.With this method “safe partiotions” of phone’s eMMC memory are being removed and recreated „safe” using „parted” command in adb shell mode. Some partitions are extremely decreased, one is totally deleted. And the most important – partition of your choice will be expanded. Example displayed below sets internal (DATA) partition as large as possible (almost).
5.You will need external micro SD card after remodelling partitions)
6.Memory swap (SD0 and SD1) required BEFORE first start of your chosen ROM!!!
7.You can restore original partition scheme using Heimdall or Odin (not tested by me, problems with Odin reported by the author of whole modification) with repartition selected.
8.Partition numbers and names are very important (crucial), so we need to create them correctly, setting beginning and the end of each one very carefully.
9.Last important thing! I use minimal gapps pack for every ROM. I didn’t tested if full gapss fit on new /system partition! You’ll have to check it by yourself!
Default partitions and sizes are displayed here:
With this guide you will achieve something like this:
[Side Note: this is just an example – you can make internal card (UMS partition) bigger, leaving /DATA partition intact, just to install bigger games – you’ll have to calculate your own values]
Part TWO: Repartition
OK., let’s do it! You have to perform all steps EXACTLY in described order!
1.Turn phone on in recovery mode, connect it to computer using usb cable.
2.Open terminal / console (Ctrl+Alt+T)
2a. Enter command:
Code:
adb devices
You should see device connected (some numbers and letters)
3.Write (press enter after each command):
Code:
adb shell
su
parted /dev/block/mmcblk0
unit kb
print
You should see default partition scheme (just as one first screen above)
OK., say goodbye to your old partitions. Deleting other partitions could (and probably – will) have irreversible consequences!!
Now we will delete partitions, starting from the last one:
Code:
rm 8
rm 11
rm 9
rm 4
Now you will encounter some error – despite of the unmounting partitions before abovementioned procedure - /cache partition is now mounted. Do not unplug phone, just enter “mount and storage” submenu in recovery, and unmount cache partition)
So let’s continue:
Code:
rm 4
rm 5
rm 3
You just deleted all “safe” partitions, enter to check this:
Code:
print
OK., it’s time to (re)create!
(SYSTEM, partition 3)
Code:
mkpart primary 105906 525906
(CACHEFS, partition 4)
Code:
mkpart primary 3848809 3948809
(DATAFS, partition 5)
Code:
mkpart primary 525906 3848809
(UMS, partition 8)
Code:
mkpart primary 3948873 3948937
(HIDDEN, partition 9)
Code:
mkpart primary 3948809 3948873
Let’s rename them properly (probably you can do it in one mkpart command, but it doesn’t matter):
Code:
name 3 SYSTEM
name 4 CACHEFS
name 5 DATAFS
name 8 UMS
name 9 HIDDEN
Almost done, let’s check:
Code:
print
Nice? Of course it’s nice!!! )
One last thing – we have to make our magic /preload (HIDDEN) partition visible for phone [it won’t boot without it!!] Because recovery won’t format it properly, lets use parted command for a last time (wait after each command):
Code:
mkfs
y
9
ext2
Now you can unplug the phone and format (in recovery) partitions:
/system
/data
/cache
OK, as I said before – you’ll have to switch storages BEFORE using phone again.
For now – you will have to manage it by yourself, just to make it short:
-for 4.2.x ROMs you can use modified vold.fstab file
-for 4.3.x ROMs – you have to manually modify build.prop, or use available zip package that will do it for you (that method is supposed to work with 4.2.x ROMs, but I didn’t test it!)
-I never used any of 4.4.x ROMs, but as I heard, there is method for switching memories too.
WARNING!
I didn’t test the way back to original partition sizes! It was tested by tesla-Madal93 though…
Sometimes (when transfer ring from one android version ROM to other, or using some old version where /preload partition was set as SWAP) you will need manualny format HIDDEN partition, just as shown above:
in adb shell mode:
Code:
parted /dev/block/mmcblk0
Code:
mkfs
y
9
ext2
FINAL WORD: If you are not sure – DON’T DO IT!!!
Screenshots are broken... I assume this deletes the "USB storage"? If then, you and the OP are bosses :good:
I can see the pictures (but are linked from other forum, i'll switch them in future), but yes - it deletes usb storage (ok, not really - new usb storage has 64KB and doesn't have to be even formatted)
Good job !:good:
Personaly i wont do it ever because 1,2 GB is enough, and if i get over that surely i have something on phone that i need to delete because i am not using it
Great post.
I would love to see the same mkpart commands to recover the preload partition space and allocate it to the data partition.
I'll do the full repartitioning thing when the team canjica CM11 major bugs have been solved. I'm not too confident about the other cm11's memory swap sustainability over time

/data 350M (assuming about 100M of actual usable app space) (20MB margin) -- in practice less than 600 will be quite tight
/sdcard 1M (depends on apps again and FAT fragments easily by design, avoid less than 100M)
Now what should be nice having are ROM variants with internal storage disabled, so that we can remove partition 8 and both bypass the need for storage swapping but also avoid some apps not desiged for 2 "SDs" getting partially broken
I just repartitioned my phone, but acidentally I partitioned partition 2 instead of 3 :/
Now when I try to rename the partition 2 again in "Modem FS" with the name command, it only names the partition as "Modem". Can someone explain me please how to rename it to the original name again?
Thank you

I restored my old nv_backup and now the device is booting... Let's see if it will work. I'm just confused, because in recovery the partition is called modemfs and when restoring nv backup it is called Modemfs....

Impossible (well, without LVM or something) because there's USB storage in the middle... but with 10 minutes and a calculator you can create your partition sizes relatively easily
If I'll make the following changes in partitions: UMS resize to 400MB, CACHEFS resize to 30MB, DATAFS resize to 2,313GB, Fota 0 MB and I'll leave SYSTEM and HIDDEN to default sizes can I restore CWM Recovery backup or flash stock rom with Odin?
The HIDDEN partition will have the same size, but the location on mmc is different, as you can see below.

Don't make CACHEFS partition under a minimum 100 MB!!!
In this partition is stored system apps' dalvik cache on all CM and CM-based ROMs, if available space is insufficient to store dalvik cache of all system apps the ROM isn't stable and has lot of FCs depending on what caches are not stored. If you want to go under 100 MB (that I advice) first check actual used space on this partition with Partition Table (available on Play Store) on your ROM, remember that every ROM has its system-dalvik cache size depending from apps' classes.dex

And why?
I've had zero problems in Android with 10 MB as long as you keep dalvik-cache away from it ( dalvik.vm.dexopt-data-only=1 and …cache-only=0)
Recovery probably uses it more though...

If you want to make something like this for your device, check out this guide here
Since I no longer have an OP 7 series device, this mod is now deprecated and won't be receiving any more updates. @invernomut0 has made a continuation of this mod using orangefox recovery. Check it out here!
Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Compatibility
This has only been tested by me on Oxygen OS Stable - Android Q.
Disclaimer
This is a DANGEROUS mod. Anything involving repartitioning is. If you fail to read and bad things happen, that's on you. Although I thoroughly tested this (managed to brick my phone once), there's always the possibility that something could go wrong with the worst case scenario resulting in a brick.
YOU'VE BEEN WARNED - Use at your own risk
What is this?
This is @mauronofrio's TWRP (see official thread here) that's been modified for true dual booting by splitting userdata into a/b slots (also does the same for metadata for encryption support). The installer script repartitions userdata for dualboot or stock based on your input.
Limitations
See the section in the github readme. MAKE SURE YOU READ THIS!
Features:
Same as mauronofrio's TWRP
Can choose between stock layout, a/b userdata, or a/b/c userdata where 'c' is a common data partition that'll show up in both roms - it's quite handy
Option to choose between ext4 and f2fs
Disables verity - fstabs are modified for dual boot and so this is a must unless you choose stock layout in which case it's optional
Option to disable forced encryption
Option to install magisk
Common Data
I recommend the a/b/c layout which includes this common data partition
If you choose a/b/c layout - you'll have a/b userdata, but you'll also get a 3rd userdata partition I call 'Common Data'
The name 'Common Data' gives away its purpose - to store files that you'll access on both slots/roms. So stuff like zips, pictures, music, TWRP backups, etc.
In TWRP, this shows up as another storage option for backup/restore and on your pc as well - your phone will have 'Common Storage' and 'Internal Storage'
In order to be accessible when booted, some parts of the system are modified so that the it'll be accessible WITHOUT root by the following mechanisms:
- The common data partition is mounted to /sdcard/CommonData
- .nomedia file is placed in CommonData so files in it won't be picked up twice if you decide to mount over internal storage as outlined below
- Furthermore, if your use case is like mine where my music files are in common data, you can make 'mounts.txt' file in /datacommon containing a list of every FOLDER to mount directly over top of sdcard. So for example:
/datacommon/Music -> /sdcard/Music
+ This of course mounts over anything there (overwrites it for as long as it's mounted) so make sure that you don't have the same folder in both datacommon and regular data
+ Note that there are 3 exceptions to this folder mounting rule:
1) All - if this is the FIRST line, ALL folders in datacommon will be mounted
2 )Android
3) lost+found
+ The reasoning should be obvious - lost+found isn't something you should need to mess with and Android is for regular data partition only - that's OS specific and should be on separate slots
+ Note that you should have 1 folder listed on every line, for example:
Code:
DCIM
Music
Pictures
ViPER4AndroidFX
Flashing Instructions
You MUST be booted into TWRP already when flashing this zip. You can grab a bootable twrp img from here
Since this modifies data - the zip CANNOT be on sdcard or data at all UNLESS you do not want to repartition/format
- If you flash from data, the zip will copy itself to /tmp and instruct you to flash it from there OR you can just install twrp/magisk/disver-fec
- You could do the above or copy it to a place like /dev or /tmp and flash it from there
- Alternatively, you can adb sideload it
Read through ALL the prompts - there's lots of options
Note that if you change partition layout, THIS WILL WIPE ALL DATA INCLUDING INTERNAL STORAGE
How to Flash Roms - If you're NOT stock layout
Nothing changes here except ONLY FLASH IN TWRP
- Roms always flash to the opposite slot. Keep that in mind and you'll be fine
- So don't take an OTA while booted - boot into twrp, switch slots, reboot into twrp, flash rom
Normal flash procedure:
1) Boot into twrp
2) reboot into twrp selecting slot you do NOT want rom installed to
3) Flash rom
4) Flash this zip
5) Reboot into twrp
6) Flash everything else
Help! I Can't Boot!
Usually this is because you switched roms without formatting data first. This should be flashing 101 but we all forget sometimes. Plus this slot stuff can get confusing
If it only happens with a/b/c and not any other layout, there's a good chance it's selinux related. Try setting selinux to permissive at kernel level with this mod(source here). If this doesn't fix it, it could be because selinux can't be set to enforcing even with the mod depending on the rom
How to Manually Repartition Back to Stock
In the event any step in the repartioning fails, the entire installer aborts. The good news is that this prevents a potential brick. The bad is that you need to manually revert back. See the README on github for the procedure. Note that if the install went fine and you want to switch back to stock later, just flash the installer again and choose stock layout

The installer will tell you if it'll wipe internal storage or not.
Basically, if you choose to change the partition layout, data will all be wiped since it'll be repartitioned. If you choose to keep your partition layout at the beginning of the install, your data will be fine.
You could just use this zip as twrp, magisk, verity/fec modifer/installer to save you the extra steps and keep with stock layout
This is super cool. Will be testing soon. Just to confirm, this means I can have a custom rom on one slot and oxygen os on the other? Also f2fs should work fine with common data right?

Yup. You can do whatever you want with either slot. This mod formats all data partitions as ext4 since that's what oneplus does. You can always reformat userdata to f2fs in twrp gui later if you want though. Same goes for common data although I don't think there's a gui option for that
How does this zip to allocate the each size of userdata ? Can be customized by ourself or automated by zip itself ?

From what I see it can not be customized through the flasher (may be possible by editing values in the zip). In case you were wondering the size of the partitions, they are 96.7gb for the common storage and 62.4gb each for the individual storages.

It's automated by installer. If you have a 128gb device:

I have the steps outlined here: https://github.com/Zackptg5/TWRP-DualBoot-Guac-Unified/#how-to-manually-repartition-back-to-stock
But what did you do? It looks like you formatted all of /dev/block/sda which is essentially a brick. You are able to restore that with msmtool btw but there will still be some device specific data that is lost and you'll likely need to file warranty claim

It was this step that I really messed up
Final step is to format the new userdata partition: mke2fs -t ext4 -b 4096 /dev/block/sda$userdata_num $userdata_size - where userdata_size can be calculated with this shell command: sgdisk /dev/block/sda --print | grep "^ *$userdata_num" | awk '{print $3-$2+1}'
with this step I used the result from sgdisk /dev/block/sda --print | grep "^ *$userdata_num" | awk '{print $3-$2+1}' I do not remember the value into the spot where userdata_size was
It looks like have been able to flash partitions manually in fastboot but the two partitions that are no longer recognized are the system_a and system_b the reason I say that is because vendor and boot flash fine on both a and b partitions. and when I send the commands to flash system a or b the reply is partition not found?! I am not sure if it would fix my problem but if I could get help to restore system partitions maybe I can get this thing to boot up.

The formatting steps is how I initially bricked my phone when I was figuring this stuff out - I since fixed that issue and made sure it'd never happen again in the zip :/
Why were you manually restoring? Did the zip cut off with partition error?
You'll need to use msmtool in this case. Even if your partition block is completely toast, it's able to bring it all back. You can grab the latest one from here: https://androidfilehost.com/?w=files&flid=296306

Download mode is really tricky too. It times out after several seconds so you pretty much have to keep holding down the key combo until msmtool picks it up and then you can release them

Download mode is really tricky too. It times out after several seconds so you pretty much have to keep holding down the key combo until msmtool picks it up and then you can release them

Modified recovery and installer script for all OP7/Pro/5G variants that re-purposes userdata for true dual booting. You can still use this as a regular stock twrp zip - one stop shop for magisk, verity, and/or forced encryption modifications
Disclaimer
I am not responsible for anything bad that happens to your device. Only experienced users should be using this mod
This is no walk in the park mod. Although I have extensively tested it, there is always the possibility of a brick with anything that involves repartitioning. Make sure you have a backup and know how to reparititon your phone back to stock (there's a guide at the end of this readme with the basics)
YOU'VE BEEN WARNED - Use at your own risk

Limitations
If you set a password, regardless of encryption status, it'll corrupt the other slot if it's also password protected.
Note that some roms set one automatically Either don't use a password on one slot, or leave one slot (I'll use 'a' in this example) unencrypted and:
Setup rom, password, and everything on slot a
Boot back into twrp, choose common data as storage, and backup userdata (if not using a/b/c layout, backup TWRP folder to your computer)
Setup rom, password, and everything on the other slot (b)
Boot back into twrp, switch back to slot a (reboot back into twrp), and restore the twrp backup
If you messed this up and are unencrypted - delete these files in /data/system if present: locksettings.db gatekeeper.password.key password.key gatekeeper.pattern.key pattern.key gatekeeper.gesture.key gesture.key
If you messed this up and are encrypted - you lost the data on that slot:
Unmount metadata in twrp gui
Format metadata with this command:
Code:
mke2fs -t ext4 -b 4096 /dev/block/sda$metadata_partnum
where metadata_partnum is the partition number of the current metadata partition (you can find this with sgdisk /dev/block/sda --print). DO NOT FORGET THE PARTITION NUMBER. If you do, you'll format all of sda which results in a brick
Reboot into twrp and format data in gui
Storage settings only supports 128 and 256gb userdata partitions
Just a cosmetic issue as it'll say that system is taking up the difference
Some other features/notes
Can choose between stock layout, a/b userdata, or a/b/c userdata where 'c' is a common data partition that'll show up in both roms - it's quite handy
Option to choose between ext4 and f2fs
Disables verity - fstabs are modified for dual boot and so this is a must unless you choose stock layout in which case it's optional
Option to disable forced encryption
Option to install magisk
Quickmode for faster rom testing
Failsafe to keep from changing slots automatically when used in conjunction with rom install
Common Data
If you choose a/b/c layout - you'll have a/b userdata, but you'll also get a 3rd userdata partition I call 'Common Data'
The name 'Common Data' gives away its purpose - to store files that you'll access on both slots/roms. So stuff like zips, pictures, music, TWRP backups, etc.
In TWRP, this shows up as another storage option for backup/restore and on your pc as well - your phone will have 'Common Storage' and 'Internal Storage'
In order to be accessible when booted, some parts of the system are modified so that the it'll be accessible WITHOUT root by the following mechanisms:
The common data partition is mounted to /sdcard/CommonData
.nomedia file is placed in CommonData so files in it won't be picked up twice if you decide to mount over internal storage as outlined below
Furthermore, if your use case is like mine where my music files are in common data, you can make 'mounts.txt' file in /datacommon containing a list of every FOLDER to mount directly over top of sdcard. So for example:
/datacommon/Music -> /sdcard/Music
This of course mounts over anything there (overwrites it for as long as it's mounted) so make sure that you don't have the same folder in both datacommon and regular data
Note that there are 3 exceptions to this folder mounting rule:
All - if this is the FIRST line, ALL folders in datacommon will be mounted
Android
lost+found
The reasoning should be obvious - lost+found isn't something you should need to mess with and Android is for regular data partition only - that's OS specific and should be on separate slots
Note that you should have 1 folder listed on every line, for example:
PHP:
Music
Pictures
ViPER4AndroidFX
Flashing Instructions (if Android 11, see second post)
You MUST be booted into TWRP already when flashing this zip (you can grab a bootable twrp image from here)
Since this modifies data - the zip CANNOT be on sdcard or data at all UNLESS you do not want to repartition/format
If you flash from data, the zip will copy itself to /tmp and instruct you to flash it from there OR you can just install twrp/magisk/disver-fec
You could do the above or copy it to a place like /dev or /tmp and flash it from there
Alternatively, you can adb sideload it
Read through ALL the prompts - there's lots of options
How to Flash Roms
Nothing changes here except ONLY FLASH IN TWRP
Roms always flash to the opposite slot. Keep that in mind and you'll be fine
So don't take an OTA while booted - boot into twrp, switch slots, reboot into twrp, flash rom
Normal flash procedure:
Boot into twrp
reboot into twrp selecting slot you do NOT want rom installed to
Flash rom
Flash this zip
Reboot into twrp
When using failsafe mode,
TWRP will boot into the slot you were in BEFORE you flashed the rom.
TWRP will almost certainly show the incorrect "current slot" at the reboot menu.
The slot selection buttons still work. If youve kept track in youre head, and the zip didnt fail; pick the correct slot now
or reboot to recovery, then switch into the slot which contains the new rom youve just installed
Flash everything else
Quickmode usage NOT RESPONSIBLE FOR BUGS, BRICKS OR MISTAKES! USE AT OWN RISK!
Change the zip name to enable quickmode options (Case Sensitive!)
keeps current layout
add the words fast or quick in the zip file to enable quickmode with the following default options:
ForceEncryption disabled for both slot
s
Magisk installed to both slots
add any of the following options to the name of the zipfile to custimize quickmode to your liking, capitilizing the letter of the slot youd like to enable that option for:
fec.ab will ENABLE force encrytion for the capitalized slot letter
su.ab or magisk.ab will ENABLE the installation of magisk for the capitalized slot letter
Example: if the file is named Orangefox-DualBoot-fast-fec.AB-su.aB.zip then:
ForceEncryption will be ENABLED on both slot _a and slot _b
Magisk will be installed on slot _b, but NOT installed on slot _a
ADVANCED USERS ONLY NOT RESPONSIBLE FOR BUGS, BRICKS OR MISTAKES! USE AT OWN RISK!
confirm.y will skip the final confirmation before any work is done, and run the options chosen or defaults if none specified
the word warp this can be used instead of fast or quick and confirm.y if you'd also like to use quickmode without confirmation
Failsafe usage / explaination
I've had a few instances where a rom doesnt agree with whats going on, and the dualboot zip gets stuck on a slot and never finishes. This results in forcing the phone off, and leaves the phone in a non bootable state, with an unprepared slot. Not to mention a stock, or worse, no recovery at all. Bootloop city.
Enter the failsafe option: just add ` nofail ` or ` failsafe ` (case sensitive) to the zip name like above, and the zip will revert the slot change caused by the rom install and keep you able to boot back into the current slot's TWRP so you can sort out the slot youre working on. Pair this with a usb drive or commondata, and youre (relatively) safe to flash on the go, or from your bed with the computer off.
Notes
After applying the failsafe, the reboot screen in TWRP will ALMOST CERTANLY show the incorrect slot until you either manually select a slot or reboot recovery.
This adds a step or two to the flashing process, make sure you've read that.
[/QUOTE]
Help! I Can't Boot!
Usually this is because you switched roms without formatting data first. This should be flashing 101 but we all forget sometimes. Plus this slot stuff can get confusing
If it only happens with a/b/c and not any other layout, there's a good chance it's selinux related. Try setting selinux to permissive at kernel level with this mod (source here).

How to Manually Repartition Back to Stock
In the event any step in the repartioning fails, the entire installer aborts. The good news is that this prevents a potential brick. The bad is that you need to manually revert back
Boot into twrp. If sgdisk is not present in sbin, grab it from this zip (in tools) and adb push it to /sbin and chmod +x it
sgdisk /dev/block/sda --print Note that /dev/block/sda is the block that userdata and metadata are stored on - no other block is touched by this mod. This will show up the current partition scheme. Stock looks something like this (on OP7 Pro):
PHP:
Number Start (sector) End (sector) Size Code Name
1 6 7 8.0 KiB FFFF ssd
2 8 8199 32.0 MiB FFFF persist
3 8200 8455 1024.0 KiB FFFF misc
4 8456 8711 1024.0 KiB FFFF param
5 8712 8839 512.0 KiB FFFF keystore
6 8840 8967 512.0 KiB FFFF frp
7 8968 74503 256.0 MiB FFFF op2
8 74504 77063 10.0 MiB FFFF oem_dycnvbk
9 77064 79623 10.0 MiB FFFF oem_stanvbk
10 79624 79879 1024.0 KiB FFFF mdm_oem_dycnvbk
11 79880 80135 1024.0 KiB FFFF mdm_oem_stanvbk
12 80136 80263 512.0 KiB FFFF config
13 80264 969095 3.4 GiB FFFF system_a
14 969096 1857927 3.4 GiB FFFF system_b
15 1857928 1883527 100.0 MiB FFFF odm_a
16 1883528 1909127 100.0 MiB FFFF odm_b
17 1909128 1913223 16.0 MiB FFFF metadata
18 1913224 1945991 128.0 MiB FFFF rawdump
19 1945992 61409274 226.8 GiB FFFF userdata
You may have different size userdata - mine is 256gb - depending on your device but that doesn't matter. You just need to see where they're located
Take note of the number (I'll call userdata_num for the sake of this tutorial) and start sector (userdata_start) for the first partition AFTER rawdump, and the end sector (userdata_end) of the last parititon on sda
sgdisk /dev/block/sda --change-name=17:metadata - renames metadata partition back to non-ab stock
sgdisk /dev/block/sda --delete=19 - this deletes the entire partition - use this command for each user/metadata partition after rawdump (ones generated by this zip)
sgdisk /dev/block/sda --new=$userdata_num:$userdata_start:$userdata_end --change-name=$userdata_num:userdata - this creates the new userdata partition
Final step is to format the new userdata partition: mke2fs -t ext4 -b 4096 /dev/block/sda$userdata_num $userdata_size - where userdata_size can be calculated with this shell command: sgdisk /dev/block/sda --print | grep "^ *$userdata_num" | awk '{print $3-$2+1}'
MAKE SURE YOU VERIFY ALL VARIABLES HERE ARE SET PROPERLY - if you mess this up, you could format all of sda resulting in a brick
Run sgdisk /dev/block/sda --print again to make sure everything is correct and then reboot back into twrp

Hi. All your data will be wiped and you have to reinstall both slots OS since this is repartitioning your userdata into A and B so do a Backup of all your data before.
It works great with A10 and A11. I had a little issue because I had A10 on A and B slot and when flashed this, then A11 ROM, rebooted to other slot flashed this again A11 was working great, but when tried to switch back to the slot with A10, after boot my pin wouldn't work anymore, so needed to delete locksettings.* an *.key files from /data/system.
Thanks for the great job!

Only set a PIN on one of the slots. Otherwise you will have that issue that your PIN does not work anymore on the other slot if you set it on both!!

Ok, just give me a minute, already installed another ROM, will try to give info u asked in a few minutes. Someone told me when i tried to do same with twrp dual boot that twrp can't yet decrypt OOS Beta 17 and 18
IDK what happened but now my touchscrren is not working...
After stuck at patching I rebooted into fastboot changed active slot to other slot, rebooted into recovery, it enter in OrangeFox Recovery but no touch...
Got a bit scared there... Rebooted to system then back to recovery and touch is working now...
But there is no /tmp folder...

Dualboot still no work with oos beta 17 and 18,,its always stuck when patching fstab ( decrypt).
There's init process called High Assurance Boot (HAB) that verify your system's integrity. Check the script "/vendor/etc/init/hw/init.mmi.hab.rc".
This command show many values, which one to pick.
gdisk /dev/block/sda --print | grep "^ *$userdata_num" | awk '{print $3-$2+1}'
edit: typo, worked fine now...
Tried it with Beta 19 and doesn't work with that either

Files restored
Works great, tested with multiple ROMs...
Having below issues
1. Even if pin not setup in secondary ROM, need to delete files otherwise pin in primary is not accepted
2. After every flash of this recovery, all my magisk settings, modules are all lost
3. Images and videos in common data not visible in gallery
This is a port of Lanchon REPIT.
- Nexus 10 Manta -
Disclaimer:
I am not responsible for your actions or consequences, directly or indirectly, related to the files and/or advice offered.
It is your choice to proceed.
What is REPIT?
REPIT is a simple, safe, device-only, data-sparing, and easily portable repartitioning tool for Android devices.
See the GitHub README for more on What REPIT is. GitHub - Link
Limitations:
Requires TWRP (or TWRP based) recovery.
Does not support encrypted devices.
Will cause data loss if the repartitioning process is externally interrupted.
See the GitHub README for more on Limitations. GitHub - Link
---
Notes:
A few years ago (September 2018), I made a port of REPIT for deb,flo and manta that was spread out between multiple threads.
Some comments and instructions were lost in thread chatter or just in a different thread altogether.
The file name actually configures the repit script.
Noted that you may have to toggle MTP Disable, Enable, Disable.
Noted that you may have to reboot into TWRP after disabling MTP.
Remember /tmp is wiped after a reboot. Copy repit to /sdcard and after rebooting back into TWRP, copy it from /sdcard to /tmp using TWRP File manager.
Noted that you may have to unmount cache and data.
Do NOT flash repit from USB/OTG.
This is designed for a stock partition layout. If your device has been modified and a vendor partition was created, REPIT will not work.
Side note:
Lanchon added Nexus 7 (2013) to the official list. (November 2019)

Be Careful.
There are always risks involved when you start messing around with a device.
If something goes wrong, you may end up with a non-working "bricked" device.
This is especially true when you start modifying partitions.
Backup what you want to save and store it off device.
Copy it to your computer, cloud storage, USB, ...
Instructions:
This operation might take a long time and must not be interrupted.
- Depending on the device and REPIT configuration, this might take a few hours.
Make sure your battery is fully charged or mostly charged.
- You can connect to a charger while the REPIT script is running. May or may not charge depending on the recovery.
How To:
If you already have a ROM installed, repit will backup, change the partition, restore and resize.
- You can just reboot once the script finishes.
Boot into TWRP
Swipe to Allow Modifications
Copy the repit zip to /tmp
Disconnect from computer
Disable MTP
Disable MTP TWRP -> Mount
Install repit
TWRP -> Install -> navigate to /tmp and flash the repit zip
Reboot to system
If you are doing a clean install, add the +wipe option to system in the zip file name. This will speed up the partitioning since system will not be backed up and restored.
lanchon-repit-20210221-cache=16M+wipe-system=1.3G+wipe-data=max-manta.zip
- Reboot back into TWRP after the script finishes.
- Then follow the instructions from the rom thread to install the rom you are going to use.

Cheers all.
Note about configuration.
The user configuration is done by renaming the zip file before flashing it.
The modifiable partitions are cache, system and userdata (7, 8 and 9).
The actual partitioning is done by a sector range. This is declared inside the script along with a default configuration.
Code:
# the set of partitions that can be modified by REPIT:
# <gpt-number> <gpt-name> <friendly-name> <conf-defaults> <crypto-footer>
initPartition 7 cache cache "same keep ext4" 0
initPartition 8 system system "same keep ext4" 0
initPartition 9 userdata data "same keep ext4" $footerSize
# the set of modifiable partitions that can be configured by the user (overriding <conf-defaults>):
configurablePartitions="$(seq 7 9)"
...
# the set of contiguous partitions that form this heap, in order of ascending partition start address:
heapPartitions="$(seq 7 9)"
# the disk area (as a sector range) to use for the heap partitions:
heapStart=$(parOldEnd 6) # one past the end of misc.
heapEnd=$deviceHeapEnd # one past the last usable sector of the device.
The default zip name lanchon-repit-20210221-cache=16M+wipe-system=1.3G-data=max-manta.zip
Creates a 16M cache partition, the wipe option (+wipe) will stop the backup and restore of cache.
Creates a 1.3G system partition, since there is no wipe option, the system partition will be backed up, restored and expanded or compressed.
The rest of the space is used for userdata. (data=max) again, since there is no wipe option, data will be backed up, restored and expanded or compressed.
Setting a 16M cache and a 1.3G system, userdata will not be reduced. If system is set beyond 1.3G, userdata will be reduced by the same amount.
If you change the name to lanchon-repit-20210221-cache=16M+wipe-system=1.5G+wipe-data=max-manta.zip
Creates 16M cache partition, the wipe option (+wipe) will stop the backup and restore of cache.
Creates 1.5G system partition, the wipe option (+wipe) will stop the backup and restore of system and you will need to install a rom.
The rest of the space is used for userdata. (data=max) again, since there is no wipe option, data will be backed up, restored and expanded or compressed.
If you change the name to lanchon-repit-20210221-cache=16M+wipe-system=1.3G+wipe-data=max+wipe-manta.zip.
This will create a 16M cache partition, a 1.3G system partition and use the rest for userdata.
Since the wipe option is added to all, no backup and restore is done. Only empty/formatted partitions are created.
This will speed up the partitioning if you are doing a clean flash.
Userdata is erased also so, make sure to backup what you want/need to keep off device.
See the GitHub README for more on how to configure. GitHub - Link
Cheers all.
