Custom MTD partitions

Hello world! I have no new information to provide, but if you're S-OFF and feeling brave THIS works on the Legend. I use CWM 3.0.1.9 and CM 7.0.2, I haven't tested it on any other versions.
I chose a 150MB system partition and a 20MB cache partition. I now have a 295MB data partition. Enjoy! ( echo "mtd 150 20" > /sdcard/mtdpartmap.txt )
Resources:
ClockworkMOD 2.1.0.7: http://www.mediafire.com/?l3c3kacbp8w0phm
ClockworkMOD 3.0.1.9: http://www.mediafire.com/?eldxgcsdb813zze
If this is in the wrong place, and I apologise if it is, I'll get it moved

Good idea
tnx

I'll be trying this out after my exam tomorrow since my Legend is only "sitting" around nowadays
Thanks for the info TGF!

Gonna try this myself too, will report back

Thank you dude !
Is it better than S2E ? In terms of speed I mean.

Err... It's probably slightly safer in the long run, as the internal memory in the Legend is designed for constant rewrites, whereas the SD card isn't (not in such small chunks anyway). Obviously changing the partition sizes like this is never safe though.
I don't think either is any faster, but this method saves you SD card, but carries the risk of completely bricking your phone.

You can't brick your phone with an S-OFF bootloader and a recovery lol
Working great, moved away from my customised sense to CM7.1, allocated 160/2 so data is 303.1MB now (CM bind mounts /data to it automagically)
Have 5.7MB free on /system with gapps on it
98.1MB free with all my apps installed back, none on SD, faster bootup and SD mount/unmount

You can brick it still, I can assure you. But yes, it is harder to do. ;-)

[Q] Convert SDCard to MainMem so External_SD becomes SDCard?

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,
JMG

check this
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.

[Q]How to remove built-in APPS in a ROM before installing?

Hope somebody can help me if possible...
I want to remove certain Apps that I don't want before I install certain ROM using CWM, because once installed I don't have a way to uninstall it.

Just open ur custom rom zip and go to system/app just delete app that u dont want to install.....
u can delete them after flashing ur rom just install root explorer and there go to system/app delete app that u dont want simple!

Deleting from Root Explorer after installing ROM is a better way.
I don't know why, but opening the zip package and deleting apps, and re-zipping the ROM again may cause the ROM to stuck at ANDROID logo.
Maybe its ROM signing zip issue?

Thanks for the quick reply...
But will it free up internal memory if I deleted them using the Root Explorer?
The reason why I want to remove them before installing so that I can save more internal memory on my phone.

Yes, because System apps are installed in Phone's internal memory.
Anyways don't delete apps which you're not sure about its behaviour. It may cause constant FC's and ROM will not be usable.

system apps are not installed in the internal memory they installed in /system partition and use the space of /system partition
deleting apk with root explorer will not uninstall the app completely the data of system app will remain in the /data partition and will consume space use system app remover to remove apps

just open it with winrar/7zip.. go to system - app - delete the apks you won't to install...

But where do you think, the /system partition is ? I mean located.

I agree, I agree, I agree and I agree all are different partitions with different capacity. But do you have any idea what I meant ?
I just simply meant its located in Phone's memory ie, internal. That's it.
I have made bold your reply, because that was only I needed.
And I guess, you're making me believe its not located in internal memory which we install apps on Phone. If yes, sorry for making my query ambiguous.

[Q] not enough space can help link2sd?

hello , my question is can i make 2. partition for link2sd?
i tryed this with 3-4gb and ext4 but when i linking apps all works fine but when i restart the phone all apps are away,
i fount it with root explorer but not more on phone. must i maby make format in fat32 is this the difference???
or give a another change to make more space i have 32gb sd cart , for nothing??? baldurs gate, assasins pirates, air supremazy or gta san andreas are great games thats i need some more space
thanks for any solution thats working and help my regarts to all (sry my bad english)

Link2sd do not working from Androids 4.1 to up.
Do not ask Why or If will ever be a patch like that, I will be glad to expand the storage on my phone too but not in this way.
The only solution at the moment is use Folder Mount App.

Yes, when you "mount" a folder you have a double data, the moved files are the real one, the other folder (where the data was before) are the ghost once (fake), folder mount do that because the system have to read to that file.
In the moment when you unpick the folder, from green to white, the ghost files disappears. Yes, it's a bit confusional but when you learn it will be easy to use.
Remember, when a folder are mounted in Folder Mount (green pick) if you delete the ghost files you will delete also the reals one, be careful.
Apps Analyzer check for Apps to move data from internal to external, just choose the destination (exc..make a folder Games) and yes, overwrite when asked, it will move the files, then they are mounted when is green.
If you have an app and Apps Analyzer do not recognize that app just do it manually, go to List of pairs, click Plus (+), browse to the folder which you want move to SD (obb or data), choose destination and name of the application, done.
Keep testing. you will understand and check always the Internal Storage, if you see it will never go up even if you have double data as the one in internal storage is the fake one.
Click thanx for me. XP

I'm using Link2sd with pac rom (cm based 4.4) without problems. Since the latest update it can even move data to the second partition, so it basically moves everything now. Perhaps you're on stock rom that does not support init.d scripts?

That is a good new but Pac Man rooms seems not stable yet and with few bugs.
Do you can mount the whole SD card as internal storage? or just the partition EXT4?

With the current Pac rom nightly I only have some camera problems, the rest seems really stable already.
Link2sd needs a second partition (which can be ext4, but also ext2/3 or even fat), so you can't use the whole sdcard.

when i used link2sd with nut 757 fw i can make linking apps (2.partition ext4)
but when i will install a new app say i dont have enough space but i have more than 3gb??? confused
help maybe a another rom, think thats work on ihackers 4.1 ?

Sorry I misunderstood. With the newest version it really moves everything connected to the app to the second partition and frees up the space in the system storage.

It's a common issue if this script, I had this many times before and this make huge problems as you "maybe" can fix it by wiping Dalvik Cache but if you do that all your saved apps data cache can be losted. So I will be glad if we will be able to mount a whole SD card instead of internal memory so we will get rid of this errors.

Do any KK Recoveries/Kernels support SD-Ext (Ext2, Ext3 or Ext4) ?

Hi All,
I've tried all the known Apps...
S2E = Not supported on anything newer than JellyBean (Android 4.1.2)
Link2SD = Corrupt, can't find partition... therefore doesn't work
Mounts2SD = Finds partition, says it works. Moves all the files... and then still says it has no space!!!!
Now all my Apps are moved, even though it's not working as says run out of space, despite having 2GB spare.... Now I can't even format that partition, as no Recovery see's it.... And so Android tells me I'm running OS in unstable mode. Format partition... (which I can't, unless I hack it...)
So, anyone know of a Recovery that supports SD-Ext ???
Thanks, Lister

No supported recovery or solution, solved by deleting and re-creating partition.
