[Dualboot] i9082 {Stock 4.2.2/AOSP 4.4.2 and AOSP 4.4.2} 23032014 V2

Hi guys,
finally I found a way to make dualboot on our beloved i9082 working!!
This way isn't as much easy as on other devices like the desire HD where
you have just to install an app and everything is done by itself, so follow this
guide at your own risk!!
THIS IS WORST RISK YOU TAKE FOR YOUR PHONE>>>>
IT MAY BRICK YOUR PHONE.....
DONT DO IT IF YOU DONT KNOW WHAT YOU DOING...
How to dual boot your I9082...
1. Make a backup of your internal sdcard to your PC!! All your data on the sd card will be gone!
2. Reboot to cwm-recovery
3. connect your phone to your pc.
4, open up cmd or a terminal and type:
PHP:
adb shell
5. type:
PHP:
cd /dev/block
parted mmcblk0
print
This looks like following
Code:
print
Model: MMC M8G1WA (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 14.7MB 15.7MB 1049kB cal

19 1212MB 2822MB 1611MB ext4 system
20 2822MB 3409MB 587MB ext4 HIDDEN
21 3409MB 7813MB 4404MB ext4 data
The last partiton i.e data partion which is our internal SD card to be re partitioned .
6. Type
PHP:
rm 21
7. Note the start and end of the data partiton. In my case its 3409 and 7813
Firstly we have to create data partition. See the size of system partition i.e 1024 MB. So the new partion will be as follows
PHP:
mkpartfs primary ext2 3409 4433
second is system 2 partition
PHP:
mkpartfs primary ext2 4433 6044
next is cache2 partion
PHP:
mkpartfs primary ext2 6044 6744
next is data2 partion
Code:
mkpartfs primary ext2 6744 7813
Code:
quit
It will say
Code:
quit
Information: You may need to update /etc/fstab.
Ignore the warning Reboot into recovery again on pc type
Code:
adb shell
mke2fs /dev/block/mmcblk0p21
tune2fs -j /dev/block/mmcblk0p21
mke2fs /dev/block/mmcblk0p22
tune2fs -j /dev/block/mmcblk0p22
mke2fs /dev/block/mmcblk0p23
tune2fs -j /dev/block/mmcblk0p23
mke2fs /dev/block/mmcblk0p24
tune2fs -j /dev/block/mmcblk0p24
This will create ext3 partition from ext2
Now convert them to ext4
Code:
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p21
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p22
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p23
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p24
Now lets check everything is ok
Code:
cd /dev/block
parted mmcblk0
print
This should look like following
Code:
print
Model: MMC M8G1WA (sd/mmc)
Disk /dev/block/mmcblk0: 7818MB
Sector size (logical/physical): 512B/512B

23 6044MB 6744MB 700MB ext4
24 6744MB 7813MB 1069MB ext4
Then
Code:
quit
Now flash your first stock ROM..ofcource custom one from recovery.
Now You can flash your desired AOSP rom as primary and dualboot enabled secondary rom.
Scripts to switch roms has been updated.
Download following dualboot enabled AOSP rom by me CosmicCm
http://www.androidfilehost.com/?fid=23329332407579496
Download following tool kit and extract on your External sd card for AOSP rom and in Internal SD for your stock rom.
http://www.androidfilehost.com/?w=files&flid=12981
Install smanager (os.tools.scriptmanager-1.apk) in zip.
Instructions on ROM switching:
1. Go to Play Store and install SManager (or included in dualboot-k2wl-V2.zip)
2. Run SManager, browse to your DualBoot folder and select "StockPrimary.sh/AOSPprimary.sh" or "AOSPSecondary.sh". depending upon which rom you want to boot into.
3. Mark favourite and su options and run the script.
4. Optional - SManager has a homescreen widget system. It lets you add buttons in your homescreens that will directly run the linked script (it has to be put in favourites first).
AGAIN this is a nuclear level risky procedure and is for ADVANCE users only....
DO NOT TRY IF YOU DONT KNOW WHAT YOU ARE DOING.......
Bugs:-
Your data partitions will be small about 1 GB.
External SD card not working in stock rom.
More?>..... You telll me...
HAPPY FLASHING.....

Does this method works with only cosmiccm ROM or it works with all aosp based ROM ?

Right now only CosmicCm but if developers willing for making their dualboot compatible rom, it wil.

Look into the second post...
reverting changes...

thanks for the tutorials k2wl
but I have a doubt
suppose ..I have installed 2 roms
now if I want to flash a mod zip( i.e pagapps or so) file for a specific rom via CWM recovery ...ll they be installed on a specific partition for a specific rom ?

for second rom its a problem, i.e AOSP.
thats why i included gapps core in CosmicCM dual boot rom.
for original primary rom stock, you can flash any mods you want.
Give me links for the mods and gapps you wanted.
i will change them into dual boot...

aahh ..that's all I want ..you rock \m/

Well ..first thanks for this procedure..the more i thank u , the less it would be mahn!..
Now, as u say that u will help guys for mods to dual boot too, the only thing i flash after ur roms is ur kernel ... I dont think its already in there in cosmic rom,And cant live without evolution kernel mahn :|..but i think kernel flashing will screw things up right??

yes it might screw things up..
bt dont worry i will add option for evaluation dualboot kernel soon.
this is work in progress.
will add more options...

general question plss..y kernel is not put as a default in ROM( I mean ur kernel and ur ROM).
Though it will not allow users of RR and carbon to use this kernel. just of curosity

Any possibility for a GUI apps or flashable zip to do all this procedure of dual boot in future development? What I mean is like GUI apps of EFS backup

[Guide] Repartition Nexus5 to increase system partition - Space for Rom & Stock Gapps

[Guide] Repartition Nexus5 to increase system partition - Space for Rom & Stock Gapps
Before I begin...don't do this if you don't know what you're doing. If you know what you're doing still don't do this. This is dangerous, and in general people don't even make good guides for this likely because it's SUCH a stupid thing to do. Samsung phones support PIT re partitioning, but for something like a Nexus, there is no easy guide. You can and likely will brick your phone...at best you will certainly wipe all data.
I wanted to install a nougat rom on my cracked-screen Nexus5, but in flashing it AND stock gapps would error out since there isn't enough room on the /system partition for both. The Nexus5 comes with a 1GB system partition which was fine way back in the day, but isn't really fine anymore. In order to pull space from the large userdata partition, we need to do some linux trickery. I chose to make /system 2GB, which may be overkill, but this phone is going to be a baby monitor/white noise machine for a 5 month old so who cares.
The prerequisite for this process is a TWRP recovery, and that's pretty much it. Ideally, fdisk would be baked in with busybox or the parted utility would be on the phone and you could use the resize function...every time I tried to use busybox's fdisk led to errors or commands wouldn't work, and parted's resize command can't deal with ext4.
The high-level procedure here is, since filesystems must be contiguous and in order so they can be addressed properly, we need to delete every partition inclusively from system to userdata, then recreate them with new storage offsets. To visualize this, here's the storage layout as it started out on my Nexus 5:
Code:
Model: MMC SEM32G (sd/mmc)
Disk /dev/block/mmcblk0: 31.3GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags

24 192MB 193MB 524kB DDR
25 193MB 1267MB 1074MB ext4 system
26 1267MB 1298MB 31.5MB crypto
27 1298MB 2032MB 734MB ext4 cache
28 2032MB 31.3GB 29.2GB ext4 userdata
29 31.3GB 31.3GB 5632B grow
Looking at that, we want to increase system (partition 25), shift crypto (partition 26), shift cache (partition 27), and shrink userdata (partition 28). If you try this on a different phone, you'll have different partitions to move.
I did this from a Debian desktop using adb, but you can use any platform that has adb. You need to download the parted binary linked below, a nexus5 Nougat rom (or any rom I guess), and a gapps package (I chose stock). Here's the commands I used:
Code:
wget http://iwf1.com/iwf-repo/parted.rar
unrar e parted.rar
sudo adb push parted /
sudo adb shell
~ # chmod +x parted
~ # ./parted /dev/block/mmcblk0 p

# Download from here: http://www.androiddevs.net/downloads/
sudo adb push aosp_hammerhead-7.1-nougat-*.zip /data/
# Download from here: http://opengapps.org/
sudo adb push open_gapps-arm-7.1-stock-*.zip /data/
sudo adb reboot recovery
# Install the nougat rom through twrp...this will resize the /system partition back to 1GB!
sudo adb shell
~ # umount /system
~ # resize2fs -f /dev/block/mmcblk0p25 2000M
~ # mount -a
# Install opengapps in twrp
~ # exit
# Reboot into system through TWRP GUI
There were some logging errors with the SantoshM nougat rom I tried, but they had no impact. I am unmounting /sdcard and that's where it's trying to stash the logs, hence errors.
You can see that the offsets for the new partitions are 1024MB higher than the originals, meaning the partition will be 1GB bigger. Here's my final partition table:
Code:
Model: MMC SEM32G (sd/mmc)

When we resize /system, we're not quite giving it the whole space...I recommend running "resize2fs /dev/block/mmcblk0p25 2048M" and seeing the error...it's easier to adjust the actual filesystem size than the partition size, so we fudge it a bit here so long as it's safe. If this test is unsuccessful, it will tell you that you're allocating more blocks than you have. If it's successful, it'll tell you to run e2fsck...this is normal, and running the resize2fs command with the -f flag overrides that warning...but it'll also allow you to allocate too many blocks, hence why you run a test first as a sanity check. For this exact procedure, 2000M is the exact maximum size.
All in all, this technique can likely be adapted to other android phones. The key is making sure you resize system by the amount you take from data, and making sure you offset all partitions in between linearly by the correct amount. I'm not sure how updates will work...anything that basically lays down a partition is gonna cause issues since it'll try to resize to the default partition size. Anything just laying down new files should be fine.
Happy hacking!

I was looking for such an option as I wanted to install a bigger gapps package then just pico. But shrinking my userdata partition is not was i had in mind. I also really do not want to loose all my data, as i am leazy
so i was thinking about just resizing /cache to a bare minimum of lets say 128mb or even less. Because as i understand /cache is just used for OTA updates - if i am mistaken here, feel free to update my knowledge.
Has anybody done this? On the Galaxy Nexus this is the way to go afaik and one would not loose things in /data.

It worked, Thank you!
What i essentially did was make a nandroid backup followed by "adb pull /sdcard/" on the computer.
Followed your instructions (just before the flashing section), pushed the sdcard data back and restored the backup.
chowned and chmodded the /sdcard directory:
Code:
chown media_rw:media_rw /sdcard
chmod 755 /sdcard
Resized the /system bit, rebooted and hoped it wouldn't 'bootloop'.
The process was nerve wracking, but now the handset is ready for a future stable ROM (I'm still on stock).

So, we need to do
Code:
resize2fs -f /dev/block/mmcblk0p25 2000M
every time we flash a new ROM?

Depends on the ROM you're installing.​

Everyone must pay attention that this guide is for 32gb model........for 16gb commands are different.......pay attention else u brick seriously you phone.....

Yes, this...my numbers show the methodology, but for the 16GB nexus 5 (or any other phone) you need to start by looking at the starting state of the partition table, then do the math from start to finish. I hope I've provided enough methodology and warnings that someone will either abort or do it right.

In general I would say that's a very bad idea...however, if you're very careful and are willing to incur some risk, it could possibly work...on the N5, since the cache partition sits between system and userdata (and more importantly doesn't touch recovery) you could theoretically try it, and if it doesn't work, undo it, all while leaving your userdata partition untouched. If preserving your data is your goal...it's probably a bad idea, but that doesn't mean it isn't possible.

How about taking space from cache to userdata? 1-1,5GB'll be unused anyway and on 16gb variant it'll be nice to have some more memory to have

Aim
To convert my Nexus 5 16GB into a Pixel using CM14.1 and Stock Open Gapps (I didn't want to keep flashing random pixel-experience.zip files)
Issue (strikethrough issues are with Stock Gapps)
When using Aroma Gapps:
1. Launcher3 crashes everytime the G search bar is clicked on
2. Google Now is not on the left pane despite my chosen packages
1. I couldn't Sign into my WiFi because no soft keyboard would appear (workaround: I created a password-less Hotspot on another phone)
2. I wasn't able to get past through the Google setup process; Google Play Services would crash every time I attempted to skip Tap & Go taking me back to a SIM card missing screen. On skipping this, I get taken to Tap & Go... and repeat
I've wiped all the caches (of course). If anyone has any ideas, it would be great.
Question to @surfrock66
You have a parted command that says:
Code:
~ # ./parted /dev/block/mmcblk0 mkpart primary 3056MB 30.8GB
Should this not be:
Code:
~ # ./parted /dev/block/mmcblk0 mkpart primary 3056MB 31.3GB
I may not have understood this fully
Thanks surfrock66 for the original method; my method varies slightly and is as follows:
Code:
Download and unpack parted.rar via the

$ sudo adb push parted /
$ sudo adb shell

No, this is not necessarily true. You will need to use Parted to analyse the partitions and then make the relevant modifications. Again, do not try this unless you are willing to potentially brick your device.

Faied copy parted to //parted : read-only file system

In TWRP, you have to choose to mount your system as read/write, for me with TWRP 3.x it's an option right when TWRP starts. If you don't do that, you can't write to / and thus can't copy the file over.

I don't have that device, but the original post here should have everything you need to re-create the process for another device. You'll have to re-calculate the offsets based on what you find when you run the original partition query.

Any ideas of what ROMs would need this?
I'm interested of the cyanogenmod in my particular case.

CM14.1 fits on the Nexus 5 /system partition WITHOUT repartitioning.
I wanted to try this because I want to flash Stock Gapps (as opposed to Nano), hoping to get a Pixel-like experience as described in my previous post (http://forum.xda-developers.com/showpost.php?p=70145560&postcount=10). However, I had lots of crashes with Stock Gapps.
Instead, I now use CM14.1 with Nano Gapps.
If you want a more Pixel-like experience, that side-loading doesn't provide (no Google Now on the left side of the Homescreen, no Pixel-like animations on clicking the G Search Bar), I have resorted to installing the Pixel Launcher and Wallpaper APKs into /system.

Re-flashing a ROM will require you to re-do these steps.

[GUIDE] Increase your Nexus 4's system partition for more space!

I got tired of installing amazing ROMs created by the talented folks here on XDA, but being held back on things like Google Apps because of the tiny /system partition we have on the Nexus 4. I looked around and found guides to increase the system space in the Nexus 5 and Nexus 7 2013, so I basically just adapted them to work on our beloved Nexus 4.
As always, do this at your OWN risk. I am not responsible for bricking your Nexus 4. I will simply list the process which I used to increase my Nexus 4's system partition (by taking a big ol' chunk from the cache partition). Remember, any sort of modification to your device of this caliber WILL void any warranty you might still have.
REQUIREMENTS:
parted (Uploaded to my Google Drive. If it downloads as a .txt, rename it to remove the extension and make it a plain file)
adb and fastboot, and preferably knowledge on how they work
Step 1: Install TWRP onto your Nexus 4 and reboot into it.
Step 2: Open up command prompt / terminal and check to see if your Nexus 4 is connected properly with "adb devices".
Step 3: Once you've confirmed that adb is fully working and your Nexus 4 is properly connected to your PC, download parted and use adb to push it to your Nexus 4 using the command:
Code:
adb push parted /
Step 4: Now enter the following command:
Code:
adb shell
and then the command:
Code:
chmod +x parted
This will enter adb shell and make the "parted" binary you pushed to your device earlier executable.
Step 5:
Now run the command
Code:
./parted /dev/block/mmcblk0 p
You should see a long list with a bunch of numbers and names in your terminal. These are the partitions on your device. parted will give you the partition number, the "start" and "end" of the partition, the size, and the name.
This is the partition layout on my device. It will probably be the same on your device, though the size of userdata may vary depending on whether you have the 8gb or 16gb Nexus 4.
Code:
~ # ./parted /dev/block/mmcblk0 p
Model: MMC 016G92 (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 524kB 67.6MB 67.1MB fat16 modem
2 67.6MB 68.2MB 524kB sbl1
3 68.2MB 68.7MB 524kB sbl2
4 68.7MB 70.8MB 2097kB sbl3
5 70.8MB 71.3MB 524kB tz
6 71.3MB 94.4MB 23.1MB boot
7 94.4MB 117MB 23.1MB recovery
8 117MB 118MB 799kB m9kefs1
9 118MB 119MB 799kB m9kefs2
10 119MB 120MB 799kB m9kefs3
11 120MB 121MB 524kB rpm
12 121MB 121MB 524kB aboot
13 121MB 122MB 524kB sbl2b
14 122MB 124MB 2097kB sbl3b
15 124MB 124MB 524kB abootb
16 124MB 125MB 524kB rpmb
17 125MB 125MB 524kB tzb
18 125MB 126MB 524kB metadata
19 126MB 143MB 16.8MB misc
20 143MB 159MB 16.8MB ext4 persist
21 159MB 1040MB 881MB ext2 system
22 1040MB 1627MB 587MB ext4 cache
23 1627MB 15.8GB 14.1GB ext4 userdata
24 15.8GB 15.8GB 524kB DDR
25 15.8GB 15.8GB 507kB grow
Step 6:
Now run the following three commands:
Code:
umount /data
umount /sdcard
umount /cache
Step 7: So, on my Nexus 4, the system partition is number 21, and cache is 22. We're kinda lucky in the fact that system and cache are right next to each other, meaning we don't have to touch any other partition.
You'll want to run these two next commands. These commands will essentially "remove" the two partitions.
Code:
./parted /dev/block/mmcblk0 rm 21
./parted /dev/block/mmcblk0 rm 22
Step 8: Now it is time to recreate these two partitions, however, when recreating them, we will make system bigger and the cache smaller. From the partitions list we got in Step 5, we can see that system starts at 159 and ends at 1040, while cache starts at 1040 and ends at 1627. The following two commands will rebuild /system starting at 159, but ending at 1590, while rebuilding cache at 1590, and ending at 1627. We are essentially stealing a large chunk from cache, since we don't really need that anymore on newer ROMs.
Code:
./parted /dev/block/mmcblk0 mkpart primary 159 1590
./parted /dev/block/mmcblk0 mkpart primary 1590 1627
Step 9: Now run this command:
Code:
./parted /dev/block/mmcblk0 p
This will bring up the partitions list, or table, again. This time, however, we'll see the new partitions where system and cache were, however, they have no names! The following two commands will name the two partitions again.
Code:
./parted /dev/block/mmcblk0 name 21 system
./parted /dev/block/mmcblk0 name 22 cache
Step 10: Great! Now the partitions should be named again! Now, we still have to format the partitions as ext4 so that we can actually use them. The following two commands will do that for you.
Code:
mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p21
mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p22
Step 11: At this point, feel free to run the command from Step 5 to take one more look at the partition table and make sure everything looks good. Now run the command
Code:
mount -a
and then type in
Code:
exit
.
Step 12: Now we are pretty much done. We've extended the system partition from approx. 881mb to 1431mb, which is a nice large chunk of memory. In the future, we could always mess with the partitions more to add even more space by stealing from userdata, but until we reach that point, I think we are pretty well set for now!
Now...
You'll want to reboot TWRP, and flash a new ROM. You can now use a much bigger Google Apps package, without any worries.
Do note, however, that flashing a ROM will "resize" system to be smaller, but this isn't a huge deal. After flashing a ROM, while still in TWRP, you'll want to go to Wipe > Advanced Wipe > check "system" then head to "Repair or Change File System", > then tap on "Resize File System." If you encounter any errors while trying to resize, try remounting system or rebooting TWRP. Afterwards, you should be able to flash your Google Apps package. I'm not sure if you need to repeat these steps after flashing things other than ROMs, but repeating this process within TWRP should work just as well.
I hope I helped y'all out and feel free to post if this guide worked for you or if you have any other comments!

Awesome! Thanks for letting me know. Glad it worked for you. :good:

thank you very much !

Thx !
Thx !

Great guide works perfectly.. has anyone tried to reverse the process and go back to stock to reflash a factory image?
I just tried it on my old Nexus 4, and after resettting the partitions, and reflashing the factory image, its just a permanent bootloop. I've cleared all the cache, tried a wipe from the stock recovery, tried flashing TWRP and wiping there.. nothing seems to work. Im not too worried, but it'd be nice if it could boot again.

Thanks for your guide. It worked like a charm for my Nexus 4.
Just a small addition: To resize the system partition automatically I placed a script in /system/addon.d:
Code:
#!/sbin/sh
#
# /system/addon.d/10-resize-system.sh
#
. /tmp/backuptool.functions
case "$1" in
backup)
# Stub
;;
restore)
# Stub
;;
pre-backup)
# Stub
;;
post-backup)
# Stub
;;
pre-restore)
/sbin/resize2fs /dev/block/platform/msm_sdcc.1/by-name/system
;;
post-restore)
# Stub
;;
esac

If it doesn't work for you
Thanks for this great guide!
Decided to breath some new life into an old N4 in my family and now it's going (very) strong again with LineageOS 15.1. Still had to clear a bit over 100 MB with .gapps-config from Stock-OpenGapps, but that's no biggie. I always liked to start with the big package and then remove everything that I don't need from it.
Second issue gave me some headaches at first.
"Resize File System" in TWRP apparently worked and Gapps-Install went through (~100 MB free at the end), but boot would fail and crash back to recovery.
(I'm using the daily LOS-nightlies by Milaq and Stock-Package from OpenGapps, maybe it's no problem with other ROMs and/or Gapps-Packages.)
Turns out the fix in TWRP wasn't really working, nevermind what partition size it shows for /system afterwards. It's somehow corrupted and still has the original size -> most of the gapps stuff get's written to nirvana, thus the failing boot.
I found the solution over in the Nexus5-Thread:

Hello guys!
Try this:
1) Install ROM
2) Backup ROM
3) Enable "Use 'rm -rf' instead of formatting" in TWRP settings
4) Format /system
4.1) Unmount /system and use 'resize2fs -f /dev/block/mmcblk0p21' in terminal (TWRP)
5) Reboot TWRP
5.1) Uncheck "Use 'rm -rf' instead of formatting" in TWRP settings
6) Restore backup
7) Install Stock OpenGapps
8) Done!
The idea behind it is that ROM installation somehow corrupt /system partition thus any write operations above normal data region silently fail.

at step 4.1 I already changed the partition number to 21 for Nexus4. In the original post it says mmcblk0p25, because on the Nexus 5 that's /system.
Now it works.
In theory this procedure should also work for updating the ROM without losing data, but haven't tested it yet. (Maybe throw in a wipe of /system as step 0...?)
To be clear: This isn't the fault of the guide to resize system-partition.
Problem is (at least certain) ROMs resetting size of file system to original and then TWRP failing to fix that doing it the easy way as described in OP (-> bug in TWRP?).
EDIT:
Above procedure also works for an update without data loss. Only difference was I did a normal wipe of /system first, "step 0" so to say.
No idea if all this is still necessary with TWRP 3.2.3-0, I'm not willing to risk a full wipe at this point. ^^

i need this...can't even install the smallest gapps package after oreo.... word!! thanks!

Really wanted to thank-you for this!
Two questions:
1. When you printed the partitions, system (21) was ext2. When you recreated it after resizing, you created it as ext4. Was that intentional?
2. You also made the claim that modern ROMs don't need such a big cache partition (your new one was 37MB, I wasn't so brave). Can you justify that claim or provide some technical details? It's not that I don't believe you (I trusted you enough to do this on my device!), just merely curious as to why/how this would be.
Thanks!

Thanks for this great guide!
Decided to breath some new life into an old N4 in my family and now it's going (very) strong again with LineageOS 15.1. Still had to clear a bit over 100 MB with .gapps-config from Stock-OpenGapps, but that's no biggie. I always liked to start with the big package and then remove everything that I don't need from it.
Second issue gave me some headaches at first.
"Resize File System" in TWRP apparently worked and Gapps-Install went through (~100 MB free at the end), but boot would fail and crash back to recovery.

I'm using TWRP 3.2.3-0 and it has this bug, too. After I followed your steps I was able to install Nitrogen OS and Open Gapps Micro in my phone without erros.
Thanks!

I believe that resize2fs step can be packaged as a flashable zip so we can batch flashing without manual intervention to it (i.e. manually resize fs on system after each rom flash) .

Maybe then more users would dare to use this solution and could calmly install gapps on Pie.
You have a lot of experience. What do you suggest?

Hi all. I only discovered this thread after independently figuring out the partitioning scheme (plain GPT) and process.
Sadly, even after this effort, it seems L-OS upgrades won't work unless L-OS devs modify their upgrade script to make use of resize2fs. Here's what happens as of package 2018-09-11:
L-OS runs backup procedure for all addons found in the existing /system/addon.d/
The above creates files (I guess) in /tmp
The /system is unmounted
The partition is overwritten with the image in the upgrade package
The script in addon.d/ are then run to restore the addons from /tmp
The problem is, the partition image in the upgrade package is for the old partition size, and therefore step 5 fails when the free space runs out. It seems the install or restore scripts don't detect this failure, and just exit without reporting an error, with 0B free space on /system.
I'm guessing the problem can be "solved" by formatting the system partition and installing LOS and all addons from scratch, but that's ridiculous. has anyone tried to raise this issue with devs? I'm about to report this in L-OS's JIRA, as I haven't seen any relevant report there.
EDIT: If anyone wants to track: https://jira.lineageos.org/browse/BUGBASH-2306

You may be able to fix that on your own by adding an add-on.d named 00-resize-system (so that's it's ran first) that just does "resize2fs /dev/block/.../system", with maybe an unmount before and a mount after. This way, LOS can just flash the full image when upgrading and the system is resized before the other addons.d scripts run.

Thanks for the tip, will give that a try. Any idea where I could find an "authoritative" docs/guide to those scripts? Just looked at the one supplied by open g-apps, and I don't really see the difference between the various commands that the script is supposed to handle (which is executed when?). Also what list_file() is supposed to provide.

You want to put the resize2fs call in the pre-restore section.
It should look like this:
Code:
pre-restore)
unmount /system
resize2fs /dev/block/platform/.../system
mount /system
;;
This includes unmounting and remounting /system which I think are needed, but YMMV. You'll need to fill in the full path to system under /dev.
There is no authoritative resource for backup scripts that I know of, but the gapps script is a good example.
P.S.: If you make it work, please post the script for others...

NOOK HD+ (Ovation) repit alternative - manually enlarge system partition

I didn't want to tax myself learning how repit works, so I used techniques that I've used for a long time on kindles.
will update if mistakes or improvements are needed. necessary binaries are in the attached zip.
THIS WILL WIPE YOUR SYSTEM PARTITION AND YOU NEED TO KNOW HOW TO GET TO RECOVERY IN SOME STEPS
THIS REMOVES THE FACTORY PARTITON , IF YOU EVER THINK YOU WILL GO BACK TO STOCK/STOCK RECOVERY BACK IT UP
remove factory partition and enlarge system
(I haven't tried this yet, but you could also remove
/system and /cache, leaving /factory alone and making a smaller /cache partition. Steps would be similar, but not exactly as below. /cache on Oreo is barely used, I think 100mb would suffice, giving 350mb additional for /system)
(these assume you have a folder called sdparted with the binaries in your current folder, otherwise just use the correct path))

[DEV][ Expand System Partition To 5GB - MediaPad M3 ]

Hello !
Here you will find the information needed to change the system partition from 2GB to 5GB - this operation is somewhat useful for installing any version of GApps on your device : Huawei MediaPad M3 8.4 Kirin version ( BTV-DL09; BTV-L0J; BTV-W09 )
Thanks to @accerian for his help, and you can also check out this tutorial for more information !
Download mkfs.ext4 and parted from here : https://forum.xda-developers.com/attachments/parted_gdisk_fdisk_mkfs-ext4-arm-zip.4494671/
Warning : the entire data partition will be deleted following this procedure, make sure you have backed up and saved it to a microsd card
Step I : extended system partition from about 2GB to 5GB ( example for a 32GB device, for 64GB devices the procedure is 99% similar, only one operation differs which will be specified at the appropriate time ) - also this example is for BTV-DL09 which is with LTE capabilities.
- extract "mkfs.ext4" and "parted" from previously download archive and put them into a new created tmp directory
- connect the device to the computer via the USB cable and bring the device into TWRP revovery with this command :
> adb reboot recovery
- copy the two executable files from the computer to the device :
> adb push tmp data/local
> adb shell
# cp -r data/local/tmp/mkfs.ext4 sbin/mkfs.ext4
# chmod 0777 sbin/mkfs.ext4
# cp -r data/local/tmp/parted sbin/parted
# chmod 0777 sbin/parted
- launch the "parted" function as follows :
# parted /dev/block/mmcblk0
- display all properties of all partitions : (I wrote what needs to be displayed as a command before pressing enter, so you just have to type "print" and press enter because (parted) is already displayed as promter ... be careful not to type (parted) twice in the following commands)
(parted) print
- go to line 43, which should be the same for all devices :
43 1174MB 3255MB 2080MB ext2 system msftdata
44 3255MB 3456MB 201MB ext4 cust msftdata
45 3456MB 3490MB 33.6MB ext4 version msftdata
46 3490MB 4127MB 638MB ext2 vendor msftdata
47 4127MB 4329MB 201MB ext4 product msftdata
48 4329MB 4333MB 4194kB hisitest2 msftdata
49 4333MB 31.3GB 26.9GB userdata msftdata
Click to expand...
Click to collapse
- if line 43 is not identical to this one here, please stop the process by writing quit and enter, I'm waiting for a private message with what is written on line 43 in the case of your device so that I can guide you correctly .
- assuming that all devices have the same system partition ( the same 43 line ) - approximately 2GB, we go to the next steps:
- access the Mount menu in TWRP and uncheck Data, and follow the steps below step by step :
(parted) rm 49
(parted) rm 48
(parted) rm 47
(parted) rm 46
(parted) rm 45
(parted) rm 44
(parted) rm 43
(parted) mkpart system ext2 1174 6501
(parted) name 43 system
(parted) set 43 msftdata on
(parted) mkpart cust ext4 6501 6702
(parted) name 44 cust
(parted) set 44 msftdata on
(parted) mkpart version ext4 6702 6736
(parted) name 45 version
(parted) set 45 msftdata on
(parted) mkpart vendor ext2 6736 7374
(parted) name 46 vendor
(parted) set 46 msftdata on
(parted) mkpart product ext4 7374 7575
(parted) name 47 product
(parted) set 47 msftdata on
(parted) mkpart hisitest 7575 7579
(parted) name 48 hisitest2
(parted) set 48 msftdata on
- for devices with 32GB :
(parted) mkpart userdata 7579 31.3GB
- for devices with 64GB :
(parted) mkpart userdata 7579 62.5GB
(parted) name 49 userdata
(parted) set 49 msftdata on
(parted) quit
Step II : activating partitions for reuse :
# mkfs.ext4 /dev/block/mmcblk0p43
# mkfs.ext4 /dev/block/mmcblk0p44
# mkfs.ext4 /dev/block/mmcblk0p45
# mkfs.ext4 /dev/block/mmcblk0p46
# mkfs.ext4 /dev/block/mmcblk0p47
# mkfs.ext4 /dev/block/mmcblk0p49
- go to TWRP -> Wipe -> Advanced Wipe -> select System -> Repair or Change File System -> Change File System -> EXT4 -> Swipe to Change
- go to TWRP -> Wipe -> Advanced Wipe -> select Vendor -> Repair or Change File System -> Change File System -> EXT4 -> Swipe to Change
- go to TWRP -> Wipe -> Format Data -> yes
- reboot device from TWRP to TWRP in order to use data again after formated !
- go to TWRP -> Wipe -> Advanced Wipe -> select Dalvik/ART Cache, Cache, Data, Internal Storage, System, Vendor -> Swipe to wipe
- copy the new updated of LOS 17.1 with system partition of 5GB into your device
- copy any GApps arm64 Android 10 to your device
- Install them like always, enjoy !
Mention :
- if your device is WiFi only, you may have fewer partitions .... the above instructions can be easily adapted from case to case !
The main idea is that we must first find out what position the system partition is in, in this case it was at position 43 which corresponds to /dev/block/mmcblk0p43 - then we need to delete all partitions from userdata to system, and recreate them in the same order !
To calculate the start and end position, it is again very easy : for example the system partition starts from the initial position 1174, which is the same as the end position of the previous partition 42 (42 1160MB 1174MB 14.7MB reserved3 msftdata), and the end position was incremented by 5327 in this case (almost 5GB), resulting in 6501. .. the next partition 44 (cust) will have the starting position 6501, and the end position will be incremented by 201 (i.e. 201MB) as shown on line 44 (44 3255MB 3456MB 201MB ext4 cust msftdata)
If really needed, a concrete example will be added here for WiFi only devices !

Thanks for this guide.

Thank you surdu_petru.
The internal storage size of BTV-L0J is 16GB, is the above procedure effective?
Is it possible to restore a partition size back to its original size? I sometimes use a dd command as a way to restore from LineageOS to stock ROM. So I need to restore it to its original size before using a dd command.
According to z3DD3r, who created a tool to resize the Nexus 5 system partition, it is recommended that after changing the partition size, TWRP should also be changed.
z3DD3r said:
Because TWRP includes size of system partition. This size should match the size of system partition on device. Otherwise bad things can happen...

Is there any problem without changing TWRP?
I am sorry for asking so many questions. I am cautious about changing the partition size because it is perilous.

If you still have 49 partitions, and partition 43 (system) shows that in the above tutorial then the procedure is identical, you just have to put a lower value of the user data partition in the last corresponding line of 16GB!
- for devices with 16GB:
(parted) mkpart userdata 7579 ?? GB

There is no need to change anything, neither TWRP nor the partition to the initial value ... the most important thing is to pay attention to the Start and End position of system partition to make the calculations as accurate as possible !
I can help you if you can send me a screenshot of what the command below displays on your device (from the system down to the last partition):
> adb shell
# parted /dev/block/mmcblk0 print

Thank you for your reply.
It is good news that if each partition has the same number it is effective.
I am currently not having trouble with the size of system partitions, so I will give it some more thought.

@surdu_petru - many thanks for this guide, I found it very clear and straightforward. I wasn't sure if you were wanting confirmation that these instructions work with other models of the tablet - if so, I can confirm it works perfectly with my (wifi only, 32GB) BTV-W09.

Thanks for confirmation. I'm not waiting especially confirmation, but it's always better if you can confirm. I'm here to help in case that something goes wrong.

I'm going for the 3rd time as the first I messed up. Second I did it right but I think I have to switch it up a little as I have the WIFI, and I can't do mkfs.ext4 after doing the parted commands. But I'll keep on it to see if all the partitions are exactly correct. I know 43 is the same as the directions said to make sure. 3rd times the charm. Good luck out there

Hey man, things are kinda messed up for me at the moment.
I've followed your steps however my cmd crashed for some reason during the process. Now I can't mount data to start the process again. Using the genuine EMUI Recovery offerd at startup doesn't work because the partitions are messed up and my own recovery points are inaccessible probably due to a currupted ext sd card (you can't make this up )
Do you have any tips on how to regain control? Or are all hopes lost?
I've tried using pro-team multi tool, however their database/website seems to be unavailable at the moment...
Edit: I have it fixed now, using a sd-card I did a force update to stock firmware, that fixed the storage. Had to restart the entire process starting with TWRP installation, device was still unlocked though. Don't be stupid like me and always check your recovery data before and not after you already messed things up
