I bought new SD card i want to wipe my phone completely and install Darkys Rom. I formated my new SD card to ext2 in Ubuntu but my phone didn't recognize the file system. Then i used Clockwork to format my (external) SD card and what i did i formated my internal SD card. I'm completely failed. Can somebody give me step by step tutorial how to format external SD Card to ext2 or ext4. Also i would like to know if i will be able to copy data under windows when the phone is connected through USB.
Thank you
Sorry for my English
Hi! Please tell me why do you want to format your SD card to ext2 or ext4? There is no need for that. Just format it tu FAT and that's it. If you want to apply lagfix then do it under recovery with the lagfix option under advanced features.

I would like to have option to transfer bigger files than 4GB.

how do I format my external SD card to ext2? I have Samsung Captivate. I got Cygwin, since I use Windows. Does anyone know what commands to type in cygwin?
I want to put files larger than 4GB on my card as well.
I think this will be useful for a lot of people.
I found a thread http://android.modaco.com/content/h...an-i-bind-mount-e-g-system-sd-xxx-sdcard-xxx/
But I am a noob in Linux, and it would be GREAT to have step by step commands I would have to type in to format my external SD card, while its in the phone, etc
Possible problem I see is that the phone might not recognize external card if its ext2/3/4 . We might have to have small FAT32 partition on there as well? Or may be Froyo has that ability...
I'm looking into doing this myself, in my case so I can use symlinks to copy apps "data" folders (not the "data" partition, but the folders in /mnt/sdcard where apps put different things) onto the larger, external sdcard. It seems like it could be possible, just need to make sure the /etc/fstab file is updated properly, and of course make sure your kernel has the ext2 and/or ext4 modules loaded and running (which you probably will if you have a lagfix installed). I will play with this and post back my results here...
I have been looking for this myself for a while aswell, but on 4 different kernels and CWM v2.5 and CWM v3.0, I couldn't find any option on how to change the ext. SD to Ext4. If anyone knows how to then please post it here!

So, progress report...
Still no success in this matter, although I have learnt a bit today about Android's internal workings. After backing up my system with CWR, I first tried formatting my ext sd card with gparted on my computer. Bad choice... Even though no config files were stored in it as far as I could tell, Android "panicked" and decided to restore all my configs to default, severely crippling my system and making a lot of apps force close when I restarted the phone.
At that point I thought, since it is now broken, might as well play with it So the next thing I tried was formatting my internal sd card (only the vfat partition that gets mounted in /mnt/sdcard) to ext2, but this time using the "busybox mke2fs" command, on the terminal emulator on the phone. This seemed to be successful, and I could read and write to the new ext2 partition, although for some reason, I got the feeling that apps kept resetting their settings (not sure what caused this, didn't really looked into it much). So once that was up and running, I decided to modify the /etc/fstab file, like I would do in a normal linux environment, to automount this partition on boot, as ext2.
At this point I rebooted the phone, but hmm... Android converted the partition back to vfat. Not good. This leads me to believe there must be some kind of "recovery" commands run on startup, in case the system detects the partition is not the default file system, or something along the lines of that. At this point it got kinda late, so I decided to document my progress, restore (which thankfully left my phone the way it was at the beginning of the day) and call it a day.
So, things that I still need to find out:
1) How does the system convert the partition back to vfat on startup and how could I avoid it from doing it? Maybe by having a small vfat partition to fool it into thinking all is good and normal?
2) When I had my partition as ext2, I couldn't see it on my computer when connected via USB (I'm on a linux system so the fs being ext2 is not a problem). Wonder why...
3) If I had a small vfat partition, how would I go about mounting the ext2 partition on the same mount point after the system checks the vfat one? Maybe by binding it? Gotta look into that as well.
4) Finally, have to check why the apps couldn't maintain their settings after a certain amount of time (for example, if I opened terminal emulator and changed the colors, these would stay if I closed and opened the app again right away, but if I closed it for a while, say half an hour, and opened again, it would be back to default...)
I'm on a Galaxy S btw. If anyone has any insight on any of these matters, would be much appreciated!
Any progress? Would really like to use +4 GB files.

It is immpossible because of hardware limitations of the SD card And often if the file is big it just fail!

Not true, read the rest of the thread before u post! Its not a hardware limitation, its because Android uses fat32 as filesystem.
hello everyone,
I just wanted to check to make sure that there is no solution for this 4gb limitation with Android yet? I too have been looking for something besides resizing files.
thanks

I have ext2 on my external 32GB SDCard, just formatted it on my PC and put it in the phone, working without any problems. I just watched a full length 720p movie with DTS sound on my phone without having to re-encode the mkv
I'm using CM7.1 on my phone which auto-mounts the SDCard even with ext2. It won't work on stock ROM, but any kernel that has ext2 support should be able to read ext2-formatted cards but they might not auto-mount the sdcard.
On my PC I had to install a ext2 file system driver (google ext2fsd) for Win7 to be able to read the card when attaching the phone to the PC.
Hi there,
Is there a way to make the add the internal SD card to the main memmory? So that there would not be an internal SD card anymore?
I do not mean swapping the moutpoints around so my External_SD becomes my primary and my internal my second....
I want to get rid of the internal one alltogether (adding it to main memory).
I figure that I'll have to format the storage in a certain way... would that do it?
Can someone tell me step by step what to do?
I do have CW-mod installed.
I did search the forum, but couldnt find anything conclusive. Just hints that it should be possible...
If there already is a thread where all this is explained, please point me to it, because I couldn't find it.
Thanks,
Pfeffa-rah
I don't think this is possible , never heard of someone who did it
I have no idea how to do that. My question is... why would you want to do that?
Having an internal_sd partition adds the benefit of having big app data (such as those in Gameloft games) sit in a very fast partition and still be called "sddata".
Also, it's mountable via PC so everything in there can still be backed up. So it's best of both worlds really.
This was discussed some time ago in this thread: http://forum.xda-developers.com/showthread.php?t=1013575
There were ideas on how to remount the cards at boot. I myself come to the conclusion that since more phones start to behave in this way, app developers will have to start dealing with it. It just sucks they are mostly slow on the uptake. My main problem was the Spotify cache location being hard coded so I resorted to hack the Spotify apk.
PS. salisbury_steak: What is it with people like you that every time someone has a question on how to do something, your immediate response is "But why would you want to do that?!".

That was actually an honest question.
I wanted to understand why he wanted to do it. (i.e. What would be the advantages of it.) There was no supposed sarcasm in there.
how about the ability to install 5x more applications?
Having that stupid 5gb partition as sd card and the real sd card as a sub folder is retarded...
My 32GB class 10 cars is a lot faster than the internal one.
The internal 5gb memory is MUCH TOO SMALL!!! Most apps don't allow you to store data on the external card. If you like me and many others install some games that download aditional data + a nav app that downloads maps for europe + some streaming music app like wimp that can cache music for offline play then you are ****ed with LG's setup.
The setup CM7 uses solves the main problem but effectively wastes the 5gb by mounting it at emmc where like 0,0001% of apps are able to access it.
So adding those otherwise wasted 5gb to the main memory would be great. But i have not seen any solution to that yet :-(
Thank you Gensplejs for explaining that to them. I had no idea how to reply to that since it seemed so obvious to me.
This thread was ment to be a question about how to do it and not to discuss the usefullness of it. That is where I lost the way in other threads...
So, thanks for your replys all (realy).
But now, back On-Topic:
How would I do it?
Sent from my LG-P990 using XDA Premium App
Please don't blame me if you tried it and you screwed up your phone.. It's your choice...
Well, I don't know if this would work, but this is how I would do it (accepting the fact that I'd loose almost 2GB of /data's free space):
1. Format your internal sd card to the same file system as your /data partition is (ext3 or ext4)
2. Copy every file from /data 1:1 to your sdcard (cp -R /data/* /sdcard)
3. I don't know when and where the partitions are mounted (maybe init.rc??)...anyways change the target there and let /data point to the internal sd card partition (so it is ensured that it is mounted automatically to the new location)
4. Reboot and keep your fingers crossed
I think i figured how to do it in theory. First we need some free space at our microsd to cp /data. Then we should repartition with fdisk /dev/block/mmcblk0p8 and p9 into one partition and change vold.fstab to mount only externalsd at /sdcard as we do when we swap partitions. In theory it should work but i cant test it right now or make a script since ve gone vacations and i dont have a pc to restore in case of error
I agree.. certain apps wont store to sdcard.. its better to use the whole 8gb as phone storage, and use external sdcard as default sdcard.
Sent from my LG-P990 using XDA App
What ive found till now is that sd swapping is easy. You can do it by tweaking only vold.fstab. But repatriationing is a pain in the ass. Looks like lg has "faulty" partitions or something and to do it you must mesh up with with almost half partitions.
I had to rebuilt boot lgdrm recovery data and sdcard to make em half work. So it probably isnt worth the trouble. Also I think init.rc is built on the boot. So just remounting internal sd to /data wont work either.
sectors is not space
it says 7996, so thats 8GB
i saw it in hurry. the brain sometimes belives whats he want to belive
sorry
New to XDA
Hello everybody,
I'm new to android and i'm trying to find out how to solve the problem posted in this thread.
I see you've got the awnser but i don't know how to do this.
I've been searching google and XDA for ever but i just can't find the awnser.
Could you make a step by step howto or point out to a post how to do this.
I mean converting your external sd to ext4 and change the mounting points.
I'm a complete nood, i didn't get adb to work on my pc, ext4 recovery is not for the p990 2x.
I've read something abbout changing fstap for swapping te mounting points for sdcard and emmc, witch is also ok for me, but formating to ext4... wel i frankly don't know how to do this.
I'm quite stuk on this.
The only partitioning experience i've got is Gparted in Ubuntu or repartitioning in Windows 7.
Thans in andvance!
Greetz,

you can expand data partition , but there is a limitation of 1.75gb
Thanks davjan
Thanks davjan,
As far i can see it's indeed not worth it.
I wil have to go on and try to find out how to change the filesystem to ext4 and swap the internal and external sd.
That way i get more usable space instead of a big datastorage witch cannot contain program data.
But thanks for the quick reply.

what rom are you using? is your phone rooted?
swapping internal with internal sd is very easy
and most of the roms here on xda are ext4 , if you instal one of them they autoconvert to ext4

I you read the link provided you'll see that it makes what you want: grow internal filesystem = lower SDcard usable space. The only thing is that it doesn't seem possible is to use the whole space: system limitation. 75Markus tried high /system and /data values and phone didn't work.
See in his Mediafire Folder, 'Nvflash + guide for changing Partitions:
http://www.mediafire.com/75markus
Ext4 is now common with custom ROMs (in fact all of them).
You should search in sd-ext partition system, which was designed to artificially expand filesystem on older phones using an 'ext' partition. I didn't heard anybody using this on O2X.
If you use CyanogenMod based ROMs, your external card will be mounted ad /sdcard by default.
Switching internal and external SD
Thanks guy's,
I'll check it out.
I've been using cyanogenmod 7.1 stable with vorkkernel 20110208.
But that gave me batterydrains while using maps and nextvid ate the same time (while i'm driving).
Now i'm trying MIUI 1.11.11 with latest swift extreme.
But MIUI is very buggy so i'm thinking of going back to CM.
The only thing is that my phone won't boot with the latest vorkkernel.

You should mount /system from CWM before you install CronMod. CronMod mounts the ext partition of your SD Card as the new /data moving all the original /data files in there. Now certain applications like Google Play, Google Setting, etc needs to be in the internal memory to work properly. Otherwise they will give forced closes. With CronMod, you will not be able to move any apps to internal memory as your new internal memory is the ext partition of your SD Card. While using CronMod make sure to install only the necessary apps as installing more and more apps will make your phone more laggier. Also the maximum size of the ext partition should be 1 GB. Hope I Helped

Since the original /data partition is moved into the ext partition of the SD Card and the SD Card R/W speed is less than internal memory R/W speed, yes, it will lag. You can control this to a certain extent by using Class 8 or above SD Card and only installing the necessary apps. Don't forget more apps you install to ext partition, more laggier your phone becomes

There is a way to avoid lags (but with Class 8 or above) and that is RAM swap...on Play store there are great apps for this. Just type "Ram swap".

Yes, it's dangerous for your sdcard's life
Taken from CM12 thread as this started to become off-topic. The issue I'm trying to address is how to stuff a huge Lollipop ROM directly into internal storage, without creating a virtual slot, to increase system performance and have overall cleaner solution. Original inspiration: @Mentor.37's custom Safestrap for unused partitions, which has way too small /data for me unfortunately. (explanation)

Code for mounting the unused preinstall and webtop partitions to SD storage http://forum.xda-developers.com/showthread.php?p=59253593
Click to expand...
Click to collapse
This allows you to mount the partitions either as a new storage or to a specific directory only, in other words it does not merge the storages, just adds a mount point next to (or possibly if modified a bit on the top of) other storage. While this may be useful for taking some inherent load off /storage/sdcard0/ (i.e. mounting /dev/block/webtop to /storage/sdcard0/Downloads) for people not swapping their sdcards, it doesn't help in Septfox's intention of enlarging /data/.
I face the same problem as Septfox: I'd love to use the storage intended for running system for it, not virtually mounted storages created in the storage intended for storing media and support data. However, the outline of the storage is intended for way older and less robust system so even the /system/ is not quite enough (667 MB, which tightly fits CM12 with a small GApps package) and /data/ is also not enough for heavier use (3.22 GB). Therefore I would like to merge it with currently unused partitions: maybe join preinstall to system and webtop to data, making both big enough.
One alternative would be to mount the 1.4 GB webtop as /data/app, which currently makes about 2/5 of occupied space of my /data. Is this possible? At which point of system startup is the script in /system/etc/init.d executed (is it done by Safestrap or the ROM itself?), and at which point might the system first need to access /data/app that contains the APKs of user-installed apps? All the really needed stuff (compiled executables) is in the /data/dalvik-cache, right? Here I'm on a really thin ice, don't know much about Android's architecture, so sorry if this is a major bullsh*t - just throwing my idea in Technically what I'm talking about is such modification of the script:
Code:
#!/system/bin/sh
mount -o rw,remount /data # Not too sure about this
# - depending on whether /data is already rw or not.
# For that I would need to know when is the script
# executed. I'm almost sure this is not necessary
# though. In original script this was done to allow
# writing into /storage/.
mkdir /data/app
#mount -o ro,remount / - unnecessary, see above
#mount -t ext3 /dev/block/preinstall /storage/preinstall
# I don't see any use for small preinstall partition.
mount -t ext4 /dev/block/webtop /data/app
chmod 777 /data/app # not sure about this either,
# probably should be 771
Clean version:
Code:
#!/system/bin/sh
mount -o rw,remount /data # Unnecessary?
mkdir /data/app
mount -t ext4 /dev/block/webtop /data/app
chmod 777 /data/app # Possibly 771 instead.
Is that possible to run, or will it bootloop, what do you think?
Even better IMO would be to delete preinstall and webtop and shrink the Stock data down to maybe 200 MB so the original Stock system is still present, preventing the phone from bricking and accommodating Safestrap. The remaining space could be divided between Safe system (say 800 MB) and Safe data (over 4 GB). Are we able to do this somehow, maybe by customizing Safestrap a bit more? Or are partitions in /dev/block locked by bootloader? Also are all these and Internal storage located on the same physical chip, or are there two separate memories in the D4? Attached proposal of repartitioned layout Sizes taken from here and here.
Developers and experienced users, I would love to hear your opinion, mainly on whether repartitioning internal storage or at least mounting webtop to /data/app could work on D4. Thanks!
Addition to the original post:
I have a spare D4 with shattered screen and not working SIM slot that I bought for spare parts. Apart from GSM (or telephony altogether? I didn't try, as only option would be emergency call which I don't want to abuse, and we don't have CDMA networks here) it works fine though. I can try meddling with formatting/partitioning - it won't be too big deal if it gets bricked beyond possibility of SBF restore.

I don't think repartitioning is possible without high risk of hard bricking the device, and yes the locked bootloader does limit what can be done.

Thanks for trying! What do you mean by changing type?
As I added here in the first post, I have a spare shattered but mostly working D4 I wouldn't be too sad to see bricked - I can try out more dangerous stuff if you point me in the right direction. I'd like to help testing different approaches to repartitioning if you have some potentially harmful ideas that you wouldn't try on your own phone.
Curious question aside: where is bootloader (and fastboot) stored? Is it sitting on some other small partition? Can we mount it to be read, or even to write there? What/where is that protection that keeps us from unlocking the bootloader?
Also, concerning mounting the free partitions to other system partitions: do you think it's possible to mount them as a folder in /data (whichever we use)? Does it matter what filesystem the partitions use? What part of boot-up runs the /system/etc/init.d/ scripts? Do you think attached proposals 2 or 3 are feasible? It would still have the stock system untouched for an emergency use and Safestrap storage, but its data would be shared with the safe system, with webtop mounted as /data/app or /data/data (1.4 GB should suffice I hope) which would leave us with nice 3.2 GB for the rest. Of course, preinstall's 600 MB for /system is hardly enough for CM12 with Pico version of PA GApps so the rest of used Google apps would inflate /data a bit - but still this is probably the best option we have now.
Actually, I find the stock /system/ to be adequate. Yea, it's a tight fit, but CM12+PA Micro Gapps slots in with 30-someodd megabytes to spare, and there shouldn't be any real need for additional space on top of that. Though, I suppose there could be trouble if CM starts including larger apps.
Init.d is done by the ROM itself, and has to be enabled at build time; CM12 actually has it shut off for whatever reason (Slimkat did as well, I would imagine CM11 also did). There's an app called "Universal Init.d" in the Store, but by the time it can get around to executing the scripts, it's obviously way too late to be screwing with vital partitions : \
Worth pointing out that Safestrap appears to have proper ADB access, you might be able to do something with partitions thataway. I don't know enough about partitions and mounting in Linux to take a jab at it. Woop, looks like that's already a no-go. Maybe the bootloader does a check or three to make sure the partitions are all in order, and throws a critical error if not.
If absolutely all else fails, there's still symlinking large apps into the newly-accessible partitions that can be done, either manually or with Link2SD/similar apps. It's a bit of a hassle, but an option nonetheless.
Well, stock /system is fine but I want to keep it untouched - mainly because I don't want to install CM12 as an update over stock JB, and also to keep myself from SBFing (at least in the long run) because of trivial issues. When this option is off the plate, the remaining partitions don't seem to offer enough space to run CM11 in a non-virtual slot (as Mentor.37 offers with his modified Safestrap with a "Safe" slot with 600M system and 1.4G for data).
Symlinking is an ugly solution - used it for a while, never liked it, mainly because symlinks broke once SD got unmounted or mounted as Mass Storage, with problems remounting afterwards.
Since we can modify the system freely, I'm sure that if necessary, we could make a neater solution than using an app to create symlinks after boot. Question how early in the boot process can we add some scripts (by flashing some zipped patch over the ROM) goes to more knowledgeable devs though...
first time I just used t option in fdisk to change partition type to whatever without changing size, the second time I resized some of them and every time after 1st reboot the M logo would appear for 1 second and from now on it would go straight into fastboot without M logo, so it seems that something in bootloader is verifying the layout or something and if is not good it would stop.
I don't think that it's possible to brick it for good, use rsd to recover

Thanks to @lucize for his trying, sadly it seems we can't repartition at all
@Mentor.37, is there a source to your customized SS 3.75 available? I'd like to try and mess around with it to put the Proposal 3 from my second post's attachment to work.
Could mounting and symlinking be done from Safestrap, or does the ROM do it itself? I have ideas of various cross-linking of folders on the partitions to kind of emulate repartitioning - but I'd have to try if it works and it would need to be done either before the system boot or shortly in the process. See attachment - that's a first draft I presume for this that the user keeps stock system only for keeping the phone bootable no matter what happens in other than stock slots, so stock data would be utilized only for root and safestrap, leaving most of its 3.2 GB free.

I believe that it's impossible because symlinking "works" after kernel is loaded and safetrap take place (is loaded) before a kernel is loaded....
If I'm not mistaken, symbolic linking is a filesystem thing, something like a shortcut only more complex (after all, it's completely transparent to anything accessing it). ADB probably has commands to make links, terminal emulators in Android definitely can. I think the problem you face is making sure the mountpoint, path, etc are exactly the same both in SS and Android.
Probably better to just do both the mounting and symlinking under Android, so you can be 100% sure that everything matches. We already know /cache/ is unused most of the time under LP, and can (probably) even be unmounted while booted if needbe; why not experiment with it, rather than going straight for the other more important partitions, until you're sure what you're thinking will work?
Edit: Wikipedia has a big ol' writeup on symlinks under various systems, looks like a fun read.

I guess then this could be implemented in some early booting stage of the system by some custom .zip being patched over, kind of the way Mentor.37's ramdisks are. Unfortunately I don't have nearly enough knowledge to do it.
What I hope could be done more easily is altering SS to maybe use not only shared cache but shared data as well - then webtop could be used for safe system, leaving more then enough space for it, and we still would have fairly usable 3.2 GB data for it. Maybe we could even assign preinstall as stock data? @Mentor.37, I'd really love to hear your opinion on this, or maybe even get your alternated safestrap's source so I could try it myself
Sorry guys, I'm dropping this. I tried CM12 in stock slot and it doesn't help the system as much as I hoped for, so there's no need for this from my side.
I also mistook the process of installing ROM in Stock. I thought I have to upgrade the stock system to the new ROM in order to keep Safestrap in it, but it turns out it's independent and when "wiping" stock /system it leaves the Safestrap there, so I can easily do a clean install of a new ROM in the stock slot

About that, could you compare the difference regarding performance between CM12 on the safe slot and CM12 on the stock slot?
I currently got it running on safe slot but I'm thinking about trying to install it to stock slot, now that I sold my Lapdock and don't need Weptop mode anymore.
But I only would do it if it increases the performance of the D4.

I don't really remember unfortunately, been running it from stock slot for a while now. Before it definitely was way more laggy than now, but that's also when CM12 for D4 was in a VERY early phase.
It definitely increases the performance, I'm just not sure how much. I don't see any reason why leave original system in stock slot though, so no reason to run CM from the safe slot. I don't like the idea of mounting the ext fs with system running from it from fat storage, it's bound to generate some unnecessary overhead.
In case of any major screw-up, sbf is your friend and AFAIK can't get messed up itself It's a good idea to have the factory cable available though, just in case it for whatever reason dies on you with low battery.
Ok, still good to know, thanks! What's sbf?
Well when I got my D4 a few months ago, I thought installing on the stock slot would be dangerous (in terms of bricking) and since I had the Lapdock, I wanted to keep the stock ROM.
But since then I've read that many users have CM12 running on stock slot, so now I want to do that, too. It's just so annoying when the whole phone freezes for half a minute or so and I think that's mostly due to the limited memory (although I have 170-300 MB free most of the time).
Do I have to consider anything special or different while installing than on an install on safe slot?

Same here, I suspect it's also connected with throttled data transfer requests of multiple apps at once, but the RAM is IMO the biggest factor. In Linux RAM is almost always full and the "free" space is occupied by cache (filesystem cache or whatever else app's cache) ready to be deleted - maybe the phone is stuttering when freeing the "free" space for other use.
Weird is that my brother with almost vanilla L 5.1 on Nexus 4 has system consuming about 100M less RAM than my CM12 - device-specific drivers maybe?

If you mean on stock slot, just remember that you need to have some system installed there even in order to boot into safestrap - delete old, install new and ONLY then reboot, otherwise you're facing sbf Learned the hard way It doesn't brick your phone (meaning you can unbrick it), but it's lengthy and annoying...
@sd_shadow: Thanks, now I know. Feels kinda stupid having asked one of the FAQ's - can't remember when that happened before.

Ah that's interesting, didn't know that about Linux before. Well I always imagined that when there's little memory left, the drive somehow gets slowed down because there would'nt be enough space for some temp files or executions. But I don't really have a clue.
On the other hand, different devices showing different and inconclusive results like that is something I already experienced many years ago. ^^

Yeah I know, I had read about it before. But you can't really miss all those hints everywhere, so I think the community takes good care of spreading that time-saving information.
Actually thanks for encouraging me, because last night I flashed CM12.1 and everything onto the stock slot! Today I installed and configured most of the things I needed (including int/ext storage swap) and I have to say, it really runs better! It might not be as smooth as with a more recent smartphone, but it's definitely snappier than CM12 on the safe slot was (now it's gone and will rest in peace^^). It may sometimes take a few seconds, but most of the time it's very fluid, a great, noticeable improvement.
Additionally, now that I don't have to household with the memory anymore, I installed all the apps that I had left out on the safe slot install and even installed a couple of huge games from the Play Store (NFS:MW, NBA Jam, Batman Dark Knight, Injustice) onto my microSD card and it still runs almost without any hick-ups! I haven't tested the games yet, though.
EDIT: It really seems to have something to do with the amount of memory left on /system. After all that installing I was down to ~ 200MB (which would've been normal on the safe slot) and the phone started lagging a little bit more. But after moving some games and apps to the SD I have more than 500MB 600MB - okay after deleting the cache it's 1,26GB - free on /system and the phone runs smoothly again.

I guess you're talking about /data, not /system (different partitions, /system is usually read-only and system is installed there with stuff you flash from safestrap, everything else goes to /data or /sdcard). Yup, when /data is becoming full, you're gonna experience some strange behavior.
/data is the first "Internal storage" in Storage settings, /system is not shown there, /sdcard is the second "Internal storage" and /sdcard-ext, or "SD card", is the actual microSD in default CM12 setup. I guess you have the last two switched though.
Hi All,
I have an LG L90 Device with a full Internal Memory. It has gotten to a point where I have to delete majority of my apps to get all my things syncing, but this is really becoming annoying to deal with now.
I do have a lot of apps (I guess 35+), but I never had an issue with Internal Memory becoming full in the past. I also have a 32 GB SD Card where I am saving all photos, videos, and music (though, I rely solely on Spotify now).
I had tried the Link2SD Method, but it isn't as effective for me, as the linked apps somehow stop responding and they just disappear on my phone, prompting me to reinstall.
I really want to fix this, as I love this phone, but just hate the fact that Lollipop will not let me automatically install all apps to the SD Card, and my Internal Memory is just full, restricting me from doing many things I would like to do with the phone.
I would love help here to fix these issues.
Hmm, Bump? Would love any possible help on fixing this issue...
Another thing I also wanted to bring up is that when I do link apps to my external SD card via LINK2SD those apps somehow become unlinked, I assume when the app updates they automatically go back to the internal memory? Not entirely sure...
me too
I think a lot of people have this issue with a "system data" checked on config =>storage, i just have install another time my lollipop 5.0.2, and right after install i checked and this system data was about 4,21 GB, i would be very happy if someone knows a way to delete, or give a way to make this ocupy less room.already did wipe cache, and nothing changed. Maybe flash a tiny rom that have all functions working on the phone, just to mention, already tried some, but always have to do an emergency flash with stock rom again. As my brother above, we waiting for some advice and tutorials !
Cheers all !
a program for Android like CCleaner would be great
would clean crap and uninstall unused APP residue
CCleaner APP might help you

Thanks for the suggestion, unfortunately I have tried identical apps such as Clean Master, and it just cleans up small megabits of junk files, I am trying to find a way to at least free up a gigabyte of storage which for some complex reason seems like a really daunting task...
What have you done recently and when did you notice internal storage is full? Also what rom?
For me when I installed a custom rom for the first time, I believe that I had something extra in /cache/backup/ that caused the full storage. I believe it was a twrp backup.
hi all..anyone has the same problem??? i'm so angry, this phone is always full!!! and link2sd doesn't work
Link2SD works if you follow the instructions and have a partition on external SD formatted as ext4 (fat32 won't work to move apps). Or go to Marshmallow and use adopted storage. In any case make sure you got a reliable SD and at least Class10 speed.

Yes, it's possible. I'm using it now with RR Marshmallow 6.0 1, TWRP 3.0.0 DarkBlue, Open Gapps and a 16GB Class10 SanDisk uSD.

WOW.. is there a guide? thanks
Simply insert the uSD and go to Storage and USB, tap the 3 dots menu and format it to use as internal storage. It will format the card and move all data from /sdcard to it and movable apps to it if you choose to. You won't access internal memory anymore.
Make sure you use a fast and reliable card. Also check the pros and cons first.

only a question: why You won't access internal memory anymore. ?
by file manager with root it will be impossibile to view internal memory? only sdcard ll be accessible?
Internal memory will be used to apps and apps data only, no user accessible files or folders. Of course you can use a file manager with root access to browse the files/folders, but all user files will be on uSD (it will become /sdcard).
PS: as I said, Marshmallow will format your uSD, so copy any file you may need first.
Oook thanks
all it works!!! now my girlfriend's phone has enough memory!!!! great thanks a lot!
