I have a question that is more android-in-general than Nook specific. I am trying this out on my Nook first, as it is an unbrickable device, before tinkering with my target device (a phone). My phone also does not have Clockworkmod recovery support, so a bricked device would be fatal.
I am attempting to increase the memory available for installed apps. My phone has limited space, but a bunch of pre-installed junk that I thought I might be able to get rid of in order to make more space for more apps. Knowing that simply deleting these pre-installed apps from the /system folder does really nothing, I set about making and editing an image file from the /system partition, then reflashing this image back to phone. As I am trying this on the Nook first, here is what I did:
1. Adb into the Nook and dd the system partition to a system.img file on the sd card.
2. Copy the system.img file to my desktop and mount the image.
3. Edit the image, removing the LiveWallpapers.apk file (a hefty ~3M file), then save the result back out as a new system.img.
4. Copy the new system.img to the sd card, then adb back into the Nook and dd the system.img from the sd card back to the system partition.
Everything appeared to work fine. The Nook boots, runs fine, and the LiveWallpapers.apk file is nowhere to be seen. Problem is, there is no difference in the available memory on the device.
In retrospect, I suppose I should not have expected there to be a difference. I am under the impression that the system partition is a read-only partition, and that extra space on this partition is not available for installation of apps. I am guessing that in order to increase the memory available, I would need to resize the data partition.
So, ultimately, my question is whether or not this is correct. Do I need to resize the data partition in order to actually get more memory available for apps, or is there an easier way? If I would need to resize the partition, how would I go about doing this, and would I need to take this extra space away from the system partition (the extra memory would need to come from somewhere, I imagine). I would envision removing bloatware from the system partition, shrinking that partition as I would no longer need that much space, and giving that extra memory to the data partition. Bear in mind that I need to do all of this through adb as I will not have Clockworkmod recovery on my target device.
Alternatively, I could be out my gourd and none of this makes any sense. Feel free to let me know if this is the case.
Thanks!
You've got it right.
The Nook emmc has partitions for boot, rom, system, data, and media. Originally data was 1g and media (/emmc under CM7) was 5g, newer models have reversed this. Data is where apps and their data go.
There are threads here about repartitioning newer Nooks with lots of good discussion. It sounds like you are capable (or want to be capable) of creating a custom partition scheme; there's enough info there for you to do that.
Experimenting with an 8g SD card might be a good place to get familiar with the tools. The "size-agnostic" installer will use a pre-partitioned SD if it finds one IIRC.
Good luck!

I just wanted to re-iterate the importance of what you said here.
I have sent several people off to buy Nook Colors who were interested in developing for android, for this very reason.
Nothing else you can get your hands on ( to my knowledge ) is as safe of a dev-tool as the Nook Color, because of the first boot to sd-card.
It doesn't matter what you do to it, at the end of the day you'll have a working device unless you throw it down the stairs or something.
Bonus points for running an sd-install directly, because when you hose it you just reflash a new microsd card.
Can't reformat the card because windows only reads the boot partition? No problem - if you still have your Nook Color with it's stock software just boot it up and pop the microsd card in. The B & N software in the Nook Color will just format the card, without a care in the world for any existing partition schemes or whatnot.
You're on the right track for what you're trying to do, as the previous poster has pointed out, so just wanted to give you another vote of confidence letting you know you're doing all the right things for all the right reasons.
Thanks for the replies!
You know, I actually did the repartition of my Nook using the CWR zip file. I hadn't thought to go look through the original thread for the manual instructions. As you pointed out, I found the directions here:
http://forum.xda-developers.com/showpost.php?p=13971291&postcount=110
The only problem is that his instructions require that you boot from the SD card in order to manipulate your interal memory. This is fine and good on the Nook, but not possible with my phone. Any idea what would happen if I tried to repartition the internal memory while booting from the internal memory? Seems that this would not be possible....or at least wrought with peril. I think that my phone can boot into a fastboot mode, but have not tried that...anyone know if this would help?
Perhaps I am just playing with fire here and need to settle for cramped memory space on my phone. I am just too accustomed to my 5GB of available app space on my Nook.
Thanks again.
Well, after some more Googling, I think I might abandon the repartitioning bit. I think I am likely to brick my phone, even though I think I could do it manually on the Nook. In addition, it appears that many phones are set up so that the kernel resets the internal memory partitioning on boot....so I might also need to mess with the kernel to get this to stick. This is beyond my skill set and really not worth my turning my phone into a paperweight.
I thought of a bit of a workaround, however. As I can extract and edit the image of the system partition, I will simply install the apps that I will eventually want on my phone on my Nook instead, extract the apk's from the Nook, then insert them into the system image file from my phone. Reflashing the system image then puts these apps into the system partition instead of the data partition, effectively saving me hoards of space on my data partition. A bit laborious, but for several core apps that I know I will want and that are memory hogs, I think it will be worth it.
Anyone see any problem with this approach?
Hi mates,
When we are flashing a Custom Rom from the CWM, we are normally instructed by the Devs only to do few steps on CWM like “Wipe Data/Factory Data Reset, Wipe Cache etc.. which we simply follow, but most of the people don’t know, including me, what these options and many other options of CWM are really standing for.
When I googled, I could not find a thread which explains about these options in a single thread, so I would like to share with my friends about what I found the Common Options of the CWM here...
Obviously these are commonly applicable for all the devices which are having CWM, but I am always concern about my favorite Galaxy S II.
People who are completely new to Recovery and these options, I suggest them to read this thread first and give a thanks to it's author.
What Is Recovery & Download Mode?
The oder and segregation of the below items in the CWM menu may vary or some of them may be removed in different custom recoveries designed by respective Developer.
CLOCKWORKMODE BASED RECOVERY MENU
1) Reboot Menu :
reboot system now
This one is self-explanatory.
2) Install Menu :
choose zip from (internal/ external) sdcard /
Lets you install any zip file (with any name) from any location on your SD card. The file can be for a ROM, a kernel, an application, a theme or any mod as long as it is in recovery-flashable zip format.
apply /sdcard/update.zip
This one is essentially the same as the ‘apply update from sdcard’ option of the main menu. widely used option for installing a ROM that you have downloaded and copied to your SD card. Entering this option will bring up a screen that will allow you to browse your SD card for the zip file.
apply update from sdcard
This can be used for installation of any official or unofficial update, ROM, kernel, theme etc. that is in a zip format installable from recovery, as long as the file is named update.zip and it has been placed on the root of your SD card (i.e. not in any sub-folder). Selecting this option will bring up a rather annoying confirmation prompt but this has saved us on multiple occasions from a lot of trouble we would have been into due to accidental key presses.
toggle signature verification
Turns the signature verification on and off. When signature verification is on, you will not be able to install any custom ROMs that haven’t been signed by the developers (most custom ROMs aren’t signed). Switching it off skips the signature verification check and proceeds with the installation.
toggle script asserts
Seldom-used option for a vast majority of users. It simply turns script asserts on or off. If you don’t know about these (I don’t), it’s best not to change this option.
3) Wipe Menu
wipe data/factory reset
This option wipes all user data on the device as well as cache. Doing this will leave your phone in the state it was in when you bought it or when any custom ROM was first installed. It will also wipe any sd-ext partition that you might have setup. (see more about sd-ext below under partition)
wipe cache partition
This is a good practice to do this before flashing any ROM. The /cache partition just stores temporary files that are not critical to device operation and can be re-generated easily, this Wipes the cache partition of the device to clear all the data accumulated there over use. This is often used before installing a new ROM, app, kernel or any similar mod via recovery.
Wipe Dalvik Cache
Allows you to wipe the cache for the Dalvik virtual machine. The dalvik cache wipe is quite similar to cache wipe but it stores the post ran java applications. Since Android is JAVA based, it uses the same java virtual machine for compiling. The dalvik cache just stores post-compiled applications in order to speed up the system. Wiping this just forces the system to re-cache those application. It causes no problems but a slight hint of lag on first boot. This is required before most ROM installations and at other occasions too, for fixing some problems.
Wipe Battery Stats
Wipes the saved battery usage statistics and effectively recalibrates the battery. Useful in various scenarios when Android isn’t showing correct battery levels.
4) Nandroid menu
backup and restore Undoubtedly one of the most important features provided by a custom recovery, the backup and restore feature – also known as Nandroid backup – allows you to take a snapshot of your phone’s entire internal memory including all partitions, and save it on the SD card.
Backup
Takes a Nandroid backup, as explained above.
Restore
Lets you restore a previously taken backup. Entering this option presents you with a list of existing backups from the SD card that you can choose from for restoration.
Advanced Restore (new options are available separately to restore from external or internal SDcard in the latest CWM)
This option is similar to the Restore option but once a backup has been selected to be restored, this option allows you to choose what parts of it to restore. You can choose to restore the boot, system, data, cache and sd-ext partitions.
5) Storage menu
mounts and storage
Allows you to perform maintenance tasks on all the internal and external partitions of your android device
mount/unmount /system, /data, /cache, /sdcard, /emmc.
These options let you toggle between mounting or unmounting these respective partitions. Most users don’t need to change these options.
format system, data, cache, sdcard or sd-ext
These let you directly format any of these partitions. Take extreme care with this option as formatting any of these partitions will result in losing all data on them, especially the boot and system partitions. Formatting the system partition will remove your ROM and leave your phone without an operating system while wiping the boot partition may brick your phone unless you restore or flash another one before rebooting your device. See below more explanation about these partitions.
mount USB storage
Lets you enable USB mass storage mode for your SD card right from recovery so that you can connect it to your computer via USB and transfer any files to/from it without having to leave recovery.
6) Advanced
This section contains a few options most users will not require, Here are the options from this section:
Report Error
In case of errors, this feature can be used to save a log of recent ClockworkMod recovery operations on the SD card that you can later report from Android using ROM Manager.
Key Test
Lets you press any of the hardware keys to see if they are properly functioning, and to see their key codes.
Partition SD Card
This option gives you a no-frills way to partition your SD card properly for use with ROMs that support data2ext (a very handy hack for low internal memory devices that enables an /sd-ext partition on the SD card to be used as the internal user data storage i.e. as the /data partition). Once this option is selected, you will be given options to choose the sizes for the /sd-ext partition as well as an optional /swap partition on the SD card, and will then automatically format it for you, leaving the remaining space for normal SD card usage. This option will wipe all data from your SD card so use it with caution!
Fix Permissions
Fixes the file permissions for the internal memory partitions back to default. This is very useful as a fix for several errors and Force-Closes that start appearing after you or an application you installed and provided root access end up messing up the permissions of important files.
PARTITIONS :
The Android uses several partitions to organize files and folders on the device. Each of these partitions has a distinct role in the functionality of the device, but not many Android users know the significance of each partition and its contents. In this guide, we will take you on a tour of Android partitions, what they contain and what can be the possible consequences of modifying their content.
Let’s start with a list of standard internal memory partitions on Android phones and tablets. These are:
• /boot
• /system
• /recovery
• /data
• /cache
• /misc
In addition, there are the SD card partitions.
• /sdcard
• /sd-ext
Note that only /sdcard is found in all Android devices and the rest are present only in select devices. Let’s now take a look at the purpose and contents of each of these partitions.
/boot
This is the partition that enables the phone to boot, as the name suggests. It includes the bootloader and the kernel. Without this partition, the device will simply not be able to boot. Wiping this partition from recovery should only be done if absolutely required and once done, the device must NOT be rebooted before installing a new one, which can be done by installing a ROM that includes a /boot partition.
/system
This partition basically contains the entire operating system, other than the kernel and the bootloader. This includes the Android user interface as well as all the system applications that come pre-installed on the device. Wiping this partition will remove Android from the device without rendering it unbootable, and you will still be able to put the phone into recovery or bootloader mode to install a new ROM.
/recovery
The recovery partition can be considered as an alternative boot partition that lets you boot the device into a recovery console for performing advanced recovery and maintenance operations on it. We have already learnt about this partition and its contents above.
/data
Also called userdata, the data partition contains the user’s data – this is where your contacts, messages, settings and apps that you have installed go. Wiping this partition essentially performs a factory reset on your device, restoring it to the way it was when you first booted it, or the way it was after the last official or custom ROM installation. When you perform a wipe data/factory reset from recovery, it is this partition that you are wiping.
/cache
This is the partition where Android stores frequently accessed data and app components. Wiping the cache doesn’t effect your personal data but simply gets rid of the existing data there, which gets automatically rebuilt as you continue using the device.
/misc
This partition contains miscellaneous system settings in form of on/off switches. These settings may include CID (Carrier or Region ID), USB configuration and certain hardware settings etc. This is an important partition and if it is corrupt or missing, several of the device’s features will will not function normally.
/sdcard
This is not a partition on the internal memory of the device but rather the SD card. In terms of usage, this is your storage space to use as you see fit, to store your media, documents, ROMs etc. on it. Wiping it is perfectly safe as long as you backup all the data you require from it, to your computer first. Though several user-installed apps save their data and settings on the SD card and wiping this partition will make you lose all that data.
On devices with both an internal and an external SD card – devices like the Samsung Galaxy SII – the /sdcard partition is always used to refer to the internal SD card. For the external SD card – if present – an alternative partition is used, which differs from device to device. In case of Samsung Galaxy S series devices, it is /sdcard/External_sd while in many other devices, it is /sdcard2. Unlike /sdcard, no system or app data whatsoever is stored automatically on this external SD card and everything present on it has been added there by the user. You can safely wipe it after backing up any data from it that you need to save.
/sd-ext
This is not a standard Android partition, but has become popular in the custom ROM scene. It is basically an additional partition on your SD card that acts as the /data partition when used with certain ROMs that have special features called APP2SD+ or data2ext enabled. It is especially useful on devices with little internal memory allotted to the /data partition. Thus, users who want to install more programs than the internal memory allows can make this partition and use it with a custom ROM that supports this feature, to get additional storage for installing their apps. Wiping this partition is essentially the same as wiping the /data partition – you lose your contacts, SMS, market apps and settings.
Now whenever we install a ROM or mod that requires we to wipe certain partitions before the installation, we should be in a better position to know what we are losing and what not and thus, we’ll know what to backup and what not.

Thanks, will save later text in PDF and keep it on PC just to have one more tutorial about things
Awesome write up!! Brilliant!
As you are so knowledgeable about CWM, perhaps I can ask you a question?
When I do a backup, it says that no external SD card was found, so it skipped the external?
When I check under mounts, the only option for the external SD card is to UNmount.... This would suggest that the card is mounted, correct?
So how would I go about backing up the external card too?
Thanks!

Thank you for your appreciation,
I would like to express once again as I mentioned in the starting of the thread that this is only a humble effort of the undersigne that I searched for such information and combined at one place here....
As far as I know about your problem of SD card storage, this is a compatibility issiue which varries on one custom recovery to another, also one SD card to another. such issues are fixed by developers in their latest versions of recoveries.
I experienced once the same issue which was resolved when I changed my SD card.
And my current (touch) recovery of Redpill v1.3 allows me to Backup and restore from external SD card with all available options flowlessly.
Thanks

Of course it backs up all your installed apps and system data along with the ROM, but it do not back up the additional data which is downloaded and stored in User's partition of your SD card by the applications, such data will remain on your SD card untill you format it, available to support your apps when you return to the previous ROM.

Yes, but when I do format/wipe all, I guess then it deletes all that is on SD card as well, such as game files and music? If so, I'd rather just copy paste it on my PC, then after doing all wipes and formats, just copy back from PC

When you do normal wipes (data/ factory reset, cache, dalvik) before installing/restoring ROM, it won't touch any data which is saved in your SD Card normally, but it is more safer if you back such application data to you PC which normally find in a folder "Android/ Data /xxx" in the root of SDcard
Thanks for info.
I have read a lot on this but am still nor clear whether a wipe data/factory reset includes a full cache wipe. Most rom install instructions tell you to do both, but it seems a wipe cache is redundant if you factory reset.

Yes, you are right, I also understand the same, but the option for merely wiping cache is kept for using in some odd situations, like when we fingered to the ROM and got some error, then we got a no-wipe version of the existing ROM to reflash, such case we need only to wipe cache…. I have got an error recently on CWM when I reflashed my no-wipe Checkrom v6 without wiping anything, then I wiped only cache, problem solved…..
what ever may be the theory, do as the developers directed for their ROM…..NO RISK

Thanks for the thread, you can never know too much. On second thoughts, there's probably no danger of that.
What would be really good if you have the knowledge, is a detailed guide on CWM Edify scripting. I'm sure many people would find that useful, especially me. There doesn't seem to be a lot of good guides or information on the language, at least I can't find them yet. If you have any good links I'd definitely appreciate it as well.
Here's another bit of information, that answered a question I had....
In case anyone else has this question...
Here is the answer from:
http://android.stackexchange.com/qu...ter-no-sd-ext-found-skipping-backup-of-sd-ext
" This means you do not have an ext3/4 partition on your sdcard. This really ins't a big deal, this is like a legacy part of the nandroid backup process. CM doesn't "officially" support the sd-ext partition any more anyhow."
Hope it helps someone else... In the end, the answer is pretty straight forward.

Why? It's been stuck at 60.5mb used and 1.2GB free according to Diskinfo forever now. Ever since I restored Madvane's unrooted B180 backup & then flashed root with Magisk.
Why does it bother me? Because I have no idea what I'm talking about and I feel like maybe Cache is storing in the Data Partition where I install my apps...? Is it?
Also with 1.2GB free in the Cache parition & 1.2GB free in the System Partition, can I just partition those and make the Data partition bigger for more available Internal Storage for apps and stuff? I mean I have external storage as default location but so many files still get installed on internal and I'd like to expand that if I could alter these partitions.
Anybody done that before or can answer my questions? Thanks! Images attached
Anyone ?
I have not read of anyone here repartitioning internal storage. I don't think it's as simple as repartitioning a PC hard drive with a GUI tool.
Do you have any tools in mind to do this repartitioning? I think it would be a highly risky operation, so be sure to make full backups and note all the original settings of existing partitions before repartitioning.
You can Google threads on people repartitioning internal storage for other phones, but note the ones who ran into problems and bricked their phones.
I wouldn't mess with the partition sizes, personally.. in theory it works, but it can trigger some arcane safeguards added by oems.
Try wiping the cache partition in twrp..? Could have gotten bugged, which would throw an error and require reformatting
Is there any indication of a problem with the cache partition?
It's biggest usage would be to download an OTA file, so unless that's happening, I would expect cache partition to remain remain mostly empty as OP reported. Probably what's in there is TWRP or stock recovery logs - you can confirm with a root file manager.
Wiping the cache partition as suggested won't harm anything and it would be interesting to know what it's reported usage is after wipe and reboot.

I guess that was my question too. If there was any idication of an issue here. Seeing that free space I'd like to have it though.
On another note. There's no indication of anything being wrong with my Data partition but I formatted it to ext4 back when I bricked my phone in a hope it would fix something. But it seems fine. IDK what they default partition type was.
My data partition is ext4, which I believe is the stock default type.

I just tried it seems like a nice and easy way to tweak performance or battery.
I prefer kernel adiuator myself.. L Speed has too many generic settings which do next to nothing for actual performance, reminiscent of the many garbage tweak programs that have been out there for years. K.A. allowed for better control of the cpu governor settings, which allowed me to negate some of the impact of emui's 'battery optimization'. A little bit of entropy tweaking on top of that, and I no longer experience nearly the amount of choppiness
As I'm sure you all know, OnePlus 8 pro is a bit of a special case. We don't have twrp, so I can't partition that way, and we don't have parted in the terminal and I can't quite figure out how to install it. What I wanna do is add like 2gb to the system partition, does anyone know how?
Add 2gb for what exactly? You can't extend the partitions on the device itself. Normally you want the system partition as small as possible to free up more storage, but put simply if you want to extend the partition you would have to flash a system.img that has been extended.
This however would be pointless because having extra free space in the system partition does nothing as nothing writes to system outside of a software update.

Flashing extra stuff my dude, there's plenty of reasons to extend your partition, and that's an extremely roundabout way to do it
Like i mentioned earlier, theres parted and fdisk, I'm just looking for usage commands or syntax, not reasons not to do it.

Well you actually CAN extend system partition, my nexus 7 2013 and a lot of older devices have ways to do this. My nexus 7 2013 has 1.6gb of system partition so it can flash a11 ROMs.
