Hello everyone, as in my pic attached theses are my phones partitions, the main thing i am after is to reduce my system partition from 2gb to 500mb or 800mb and to expand my data partition by the amount to free up?(also can i reduce the cache partition too?).
the only thing i can find is this but i cant seem to even get the first step to work so i wanted to know if anyone knows of how to do this or can point me in the right direction?

hi i needed help with apps to sd card i recently rooted my g1 to cm 4.2.14.1. i was reading that it does it automatically thru this mod if you have a partitioned sd card which i do but i notice everytime i download a new app my internal phone storage goes down. i was wondering if that was normal or if its only suppose to go down on the partition? im really noob to this who rooting process so please help!
Applications not only store information in the apk, but also other places, /data/data/ for instance.
Delete the partition then see how much space applications use if you want to compare the difference. It could also be browser cache and other things that store information on the phone memory.
Cyanmod rom will automatically do apps2sd if it see a new partition EXT2
You have to do that on your own.
The easiest way I found to do that is use amon_ra's recovery 1.2.3 instead of Cyans
It has an option in the recover screen to partition and add EXT2 .
Now im new to this I dont know how to increase the default of value of XXXmb in ext 2 .
So if some one can chime in and tell me in the simplest way how to change how big the ext2 partition is that would be great.
OP I hope I helped you if you need more help PM me.
Edit I figured it out.
Just use linux to partition ext2/3 and define how much space your sd2apps will use on ext2 partition.
I'm wondering if it's possible to create an ext3/4 partition on the SD-card and use it for files over 4gb. The main reason I want this is to play with Backtrack 5 for the ARM architecture. I'm guessing it should be as simple as partitioning my SD-card w/ a Fat32 partition as the first partition and then ext3/4 as my second and then adding a mount option into the fstab file. Just wanted to run it by anyone else that has already done it, or knows a better way.
PS. In case anyone else is interested, here's a thread with partial instructions on install Backtrack (if you're familiar with Linux, figuring out the rest shouldn't be difficult): http://forum.xda-developers.com/showthread.php?t=1074723&highlight=backtrack
Edit: Just found this: http://denniskuntz.com/blog/2011/05/11/backtrack-5-on-the-nook-color/ So, it seems it's possible. But, still have the question of can you have both a FAT32 and a ext2/3/4 partition on there and keep your nook functional as normal, but have a separate partition to run BT5 off of?
Hi everyone
I'm wondering if there's a way to resize /data partition to, let's say, 500 MB because 2 GB is way too much for me and I'd like to the use the extra space on IntSD partition, because I'm running out of space on it.
Do you have any suggestions? I know it has been done on ZTE Blade by its developers via TPT method.
Cheers.
I believe this is called making a "custom mtd". Try Google to see if there is a guide for your phone.
Does anyone out there know what causes 4EXT CWM and Amon Ra all (with custom tools) all to fail in regards to seeing a formatted cache partition on EXT-2.
I have DONE EVERYTHING I can possibly think of, from using Gpart in Ubuntu, to the phone itself. Many times in the past I have made it would just leave my 2 Gig cache partition empty because NOTHING works EVER!...
Did I miss something, can you even have 4 separate functional partitions with the Nexus 1 ?
The closest I have come to something really functional is with 4EXT, it seems to go through all the stages but when I check alignment I only get the first 2 partitions (fat-32 and EXT-1) EXT-2 says it is unformatted for some odd reason! This has been performed using a full card wipe on an external source. Even still everything is seems to go as planned until I check the card. With 4EXT I attempt to force a ext3 or 4 format and it restarts the recovery ! When I check A2SDGUI it says I only have 15 megabytes for cache.
I have used black rose and set it to 220/15/201 (dla5244), tried the latest versions of 4EXT and wasted many hours before posting...
CAN ANYONE HELP !!
Download SD Formatter from here, run the program and choose under Options:
FORMAT TYPE: FULL (OverWrite)
FORMAT SIZE ADJUSTMENT: ON
This will format your µSD (be sure to backup your important stuff). When finished, try to make an ext4 partition with 4EXT recovery. You only need one ext4 partition (so no 2nd) and no swap.
Thank you for the fast response but I have tried that. Except I want this phone to work optimally and I have figured everything else out so it is hard to settle for mediocrity. I mean I know that 1 SD-EXT partition works... Even 1 + fat32 and SWAP but I can NEVER have the phone identify the SD-EXT2 partition... no matter what... In partition magic (terrabyte bootit) and of course Gpart in Ubuntu all indicate that everything is great. Except the phone doesn't use the partition and like I was saying before the 4EXT shows it as unformatted after it's format. When I force a format on the partition the software reboots !?!... And if I leave it claiming it's unformatted even though we may think it is, QND's MIUI can only see 15 megabyte cache partition !
But then why not just go back to stock roms and one partition? To your point it's hard to step back and use something less inclined for performance when it should work ? no ?
I know I am a NOOB BUT I also know that it seems like no one out there can offer CLOSURE on the matter. like "ohh that's because the N1 cannot identify a EXT2 partition" or "ohh... that's your SD card's fault it isn't aligned right etc."
I mean I can see others have had this problem and gave up, I don't want to give up unless it is a limitation of the hardware (?sd card?)
Another way to look at it is although beautiful and helpful for most... 4EXT should be focused on getting that to work, I would think... To your point everyone is confused and shouldn't have more than 2 partitions ? Doesn't seem right to me.
Anyways if you have any other ideas OR anyone else can think of a solution lets do it I want to invest time into this and make it work !!
Sincerely! !
Why should you have more than 2 partitions on your µSD? 1 fat32 for your pictures and videos and stuff, and if you don't have enough space for your apps, 1 ext4 for A2SD (maximum 1GB).
Swap is not necessary and in fact slows your system down. A thread about swap is somewere to be found here.
And why the 2GB cache partition? You already have a 15MB cache partition on your phone.. 220/15/201.
You really don't need more than 2 partitions on your µSD.
?
I am willing to accept that you are right that it isn't needed. But I am not using A2SD, I am using XPART. According to the guides I am read, the best way is with 3 or 4 partitions (Swap being the option). The Cache partition on the other hand makes sense because even with titanium backup I can see my 60 or so apps are storing a couple hundred megs in cache. So this way a dedicated partition for processing things once instead of multiple times would provide the fastest solution. Being that the n1 is not the top performer anymore (still my fave though ), any extra speed should help when I am using my phone day to day.
The QND MIUI mod by jbbandos has the following about XPART :
"You can use it with one FAT32 and one ext4 partition, as A2SD, which seems to be the more stable setup, but the recommended setup for speed is one FAT32, one large ext4 (for your data partition), one smaller ext4 (cache), and a swap partition. I'm not that much of a fan of a swap partition, as I am always afraid it will wear out the SD card precociously, but most people report it working well, and I prefer the single ext4 for stability, but YMMV. "
you can read more here :
http://forum.xda-developers.com/showthread.php?t=1084726
.......
Anyways that is what I want, and I will invest the time to get it. I believe that 4EXT is primarily in development to perform this function. But I have a problem, with the results. I realize that it may not be necessary but I would like to know the WHY as to why this doesn't work.
AS ALWAYS thank you for you help none the less..
Never used XPART, I didn't know they recommend this. I never used apps to ext scripts longer than a few days.
This is because I'd rather install 10 crappy apps less, than having a slower system. Then again, if I would use an apps to ext script, I would definitely go for stability .
Unfortunately I don't know what you could do now..
I found my previous QND build with XPROT using blackrose was good for like 7 months !!! I just wanted to update and get it working properly. I would HIGHLY recommend it as you phone sees like 1 gig of internal mem so all apps that have widgets are useful and don't need to go to SD. In my opinion it was more stable than stock !!! Honestly, great tool.
OH yeah and it is also much faster I have found !
Hello folks. Before going further I need to apologize. I really fighted to use Link2SD on my Galaxy tablet and I succeeded more or less. I thought that my tentative could be useful to others. So I posted this topic.
I worked a little more, and now I am convinced that I was wrong from the beginning.
The reality is that Apps2SD and Link2SD are obsolete utilities.
Forget creating a second volume on your external SD Card :
- Android/Samsung declare your SD Card as corrupted and always wants to reformat it.
- TWRP mounts the wrong partition and you have to manually unmout it and remount the good one
- The partitions need to be declared with a wrong type and this is really not clean
etc...
I suggest that you do not loose your time, forget Link2SD, and read this excellent topic:
https://www.xda-developers.com/divi...gles-fuse-replacement-will-reduce-io-overhead
My Galaxy tab A has only 11 Go available for the user. I bought a 128 Go external SD card to extend both /storage/emulated/0 and /data.
When you first install your SD Card, Android automatically mount this card as /storage/xxxx-xxxx.
This is a FAT volume extended on all your SD Card (128 GB for me).
This is fine for storing ebooks, music, video, and your backups.
But impossible for Link2SD to move your apps on this volume and put a symbolic link on the previous location, because FAT is not a UNIX file system. Link2SD (or Apps2SD) needs a second disk volume on partition 2 (/dev/block/mmcblk1p2) formatted with a UNIX file system (ext4 is fine).
Of course you need to have rooted your device. [A non rooted tablet is not better than a vulgar iPhone ]
To re-partition my SD Card I used ROEHSOFT PARTITION TOOL (SD-USB). (I tried unsuccessfully Aparted, it crashed every time I launch it). ROEHSOFT is convenient but tricky to be used by an advanced user :
- You cannot create a partition in a specific slot (for example /dev/block/mmcblk1p2): It automatically use first slot for the first partition you create, the second slot for the following partition, and so on.
- If you try to foul it, deleting a partition and recreating it in another empty space, it suddenly decides to reorganize your 4 slots. It really wants /dev/block/mmcblk1p1 to be the first partition on your SD Card, /dev/block/mmcblk1p2 the following, etc...
- You cannot create a partition at a specific offset inside an empty space.
After fighting with ROEHSOFT I finally won. I discovered too late that "fdisk" is part of BusyBox. If you know "fdisk" my advice is to use it instead of fighting with a software which pretends to be user friendly but is too limited.
OK, stop bla-bla and work.
1 - Dismount your SD Card : Parameters/Device Maintenance/Storage/Menu-Storage Parameter/Dismount
2 - Delete the only one partition
3 - For a misterious reason, my Android was not happy with his FAT volume on /dev/block/mmcblk1p1. Link2SD wants his UNIX volume on /dev/block/mmcblk1p2. So, if you use ROEHSOFT you need now to create a small dummy partition on /dev/block/mmcblk1p1. For me I created a 4 Go partition to be used by Linux Deploy. This partition needs to be declared as FAT32 (LBA) but should not be formatted as a FAT file system. EXT4 is a good choice.
4 - Create the second partition for Link2SD. I suggest not too much space for it, because you probably want a huge space for the third partion. This partition needs to be declared as FAT32 (LBA) but should be formatted with a UNIX file system. EXT4 is a good choice.
5 - Create the third partition to be used as SD extension for Android. This partition should be very large : you will store on it your music, your movies, your ebooks, and above all your backups. This partition needs to be declared as FAT32 (LBA). I formatted this partition as a EXFAT file system.
6 - Reboot. If you are lucky you will get two notifications : one saying that you have a corrupted memory card, and one saying that you are ready for media files. You will get those two notifications at each reboot.
8 - Recreate mounting scripts inside Lin2SD (or Apps2SD), and reboot.
7 - If you are a UNIX user just type "df -h" in a terminal to verify that the two partitions are mounted with correct sizes).
8 - You can look what Android think of your partitioning :
/Parameters/Device Maintenance/Storage/Menu:Storage Parameter/.
Do not try to mount the two first volumes and NEVER try to reformat them with Android. Those volumes are declared as corrupted but this is normal. Android does not expect to find a UNIX file system on a partition declared FAT32.
If one day, you forget this and ask to Android to reformat a corrupted partition you will have the terrible surprise that Android will not only erase your partition, but will erase everything and recreate one and only one big empty partition. (I guess that you keep all your backups on this SD Card, like me, so this is a really bad surprise).
Do not ask me why Android does not want his SD-Card on first partition. I have no idea. I guess that Android or Samsung reserve this partition for something else.
Do not ask why I had to declared all my partitions as FAT32 even if two of them are formatted as EXT4. I just realized that this configuration works well after fighting during a full day.
I hope that this topic will help some of you.
You really need the second partition on the SD? Or you can have only one ex4 partition that fills all the SD? (Remove the FAT and only have one ext4)

No, I tried but it doesn't work.
I found today a very interesting topic that I will try to master and hopefully wil, understand everything better :
https://www.xda-developers.com/divi...gles-fuse-replacement-will-reduce-io-overhead
Maybe I was wrong from the beginning : perhaps LinkSD and apps2SD are historic patch that are not useful anymore. Perhaps all the burden will be fixed easily just by not using those utilities anymore.
"sdcardfs" is something very new for me who is an old UNIX fellow. This seems to be a major improvement for Android.
I will update this topic when everything will be clear for me.
I didnt have this problem on android 6, but on android 7 . My phone wants to use ext4 as data partition and says its corrupted, link2sd detects this second partition normally, but my data partition fat 32 detected on phone settings and its says its ready but there is no option to mount it.
As far as i understand from this tutorial i need to make 1 fake ext4 partition say 1mb, then second partition ext4 for use with link2sd, and third partition fat32 for use as data storage ??
My phone is samsung j7 2016
So i did follow this , but now my phone wont detect fat32 and link2sd didnt detect 1 of other ext4 partitions
Looking for a definitive way to Root and use link2sd to have my SM-T580 use the SD as a primary parition for apps and data. Been researching and trying a dozen different methods already to no avail. Bonus if there's a way to roll it back easily. Am on the latest android release.
Thank you for all replies.

You're my saviour, thank you ! I've been fighting on the same issue for days and didn't think about that trick to declare an ext partition as FAT32 !
I know you probably won't see this, but I just wanted to tell you how much I appreciated this guide.
I have a Galaxy Tab S3 and every since going to a custom rom, I haven't been able to get this working which was such a pain with less than 23 gb of storage. The Rom improved my performance far too much for me to change back and every guide I attempted pointed me in the wrong direction but finally, I'm able to use my 120 gb SD card which has made my tablet worth using again.
To anyone who may attempt in the future,
I'm using Android 9 + Magisk. Using the Advanced type Mount script was the only way it get it functioning but I've had no issues with linking apps and no message regarding a corrupted SD card. It can take a few minutes on boot for everything to properly load in, but the apps all update and there's no performance/loading time issues.
Thanks again!
